Final report for the continuation session that started after the original 25-commit run closed. Covers:

Stats:
- 17 atomic continuation commits (db5ab0d9 -> 7d6dbbd3) plus 03056a4f for the closure summary itself
- 14 unique doc files modified
- 0 source files modified (continuation was docs-only)
- 11 source files read in full; ~20 outlined
- ~250 + lines, ~190 - lines across the doc edits

What was done (14 drift clusters with detailed before/after):
- guide_hot_reload.md: example registration + trigger_key claim
- guide_app_controller.md: filename typo + fictional hot_reload() method
- guide_gui_2.md: line 155 -> 285; reload() -> reload_all()
- guide_nerv_theme.md: 5 wrong hex values; render_nerv_fx fiction; [nerv] config fiction; 0.5 Hz -> 3.18 Hz; 1.5s pulse -> no decay
- guide_shaders_and_window.md: 3 fictional [nerv] config refs
- guide_command_palette.md: 11 -> 33 commands
- guide_mma.md: 5 algorithm drift points (has_cycle iterative, topological_sort Kahn's, tick no-promote, ConductorEngine.__init__ signature)
- guide_beads.md: dispatch line range
- guide_multi_agent_conductor.md: wholesale rewrite of pre-refactor architecture
- guide_tools.md: run_powershell signature (add patch_callback)
- guide_context_curation.md: FuzzyAnchor docstring (replace 'anchor_lines' with real field names)
- guide_simulations.md: CodeOutliner doc (add [ImGui Scope], return-type suffix, count guard)
- Readme.md: 3 line-level drift (45->46 MCP, 32->33 commands, shell_runner patch_callback)
- docs/Readme.md: file tree (24->27 guides with full alphabetical list)
- conductor/index.md: 23 -> 27 guides count

Drift patterns (6, refined from the 4 in the original handoff):
1. Thread counts
2. Line numbers
3. Removed-class claims
4. Schema fields
5. NEW: Architecture rotations (the most common in this continuation)
6. NEW: Hard-coded constants described as config keys

Bucket coverage status (final):
- A (theme) DONE
- B (logging) Partial - cost_tracker and log_pruner audited; no specific doc drift
- C (commands/palette) DONE
- D (file utilities) DONE - run_powershell + CodeOutliner + FuzzyAnchor
- E (runtime/imgui) DONE
- F (MMA orchestrator) DONE
- G (beads/vendor) Partial - beads_client read, vendor_state read, dispatch line ref fixed
- H/I done in original 25-commit run

Mixed-in user files caveat (49ac008a):
- 2 user-authored files swept in from the prior_session_sepia_20260610 track
- User aware and chose to leave the commit as-is
- Theme-track agent should treat those files as owned by that track

Verbiage lesson:
- 'fictional' is a value judgment, not a technical description
- Use 'predates the refactor' / 'stale' / 'no longer matches the source' instead
- Applied in 2 user-facing doc cleanups (guide_app_controller.md:59, guide_rag.md:322)

Recommendations for the theme-track agent:
- Read guide_themes.md:87 before touching the theme system
- Do NOT touch the guide_nerv_theme.md and guide_shaders_and_window.md updates from this session (re-verified against source)
- The theme_2.py:111 comment confirms the per-frame create-and-discard FX pattern
- Run all 4 audit scripts before committing any source code change
- The markdown_table.py spec is older than the source - check both
- The _lang_map reference in the older spec is a pre-refactor claim

Open follow-ups (none blocking):
- B/G finalization
- markdown_helper.py and markdown_table.py source verification (left for theme track)
- Test count verification (322 may drift)
- Doc freshness signal

 - Do not skip TDD - write failing tests before implementation
+- Do not use `@pytest.mark.skip` as an excuse to AVOID fixing the underlying bug. Skip markers are documentation of known failures; the failure must be addressed with priority in-session when feasible. See `conductor/workflow.md` "Skip-Marker Policy" for the full policy and review checklist.

 - Do not add comments to source code; documentation lives in `/docs`
-- Do not use `set_file_slice` for multi-line content; it's literal line replacement by design (see `conductor/edit_workflow.md`)
+- `set_file_slice` IS valid for multi-line content.

See `conductor/edit_workflow.md` for the full contract.
 - Do not use `git restore` while a user is mid-conversation without first confirming the desired state
 - HARD BAN: `git restore`, `git checkout -- <file>`, `git reset` are FORBIDDEN without explicit user permission in the same message. They destroyed user in-progress src/* edits twice in one session (2026-06-07). If you think you need one, ASK FIRST.
 - No giant edits: if your `manual-slop_edit_file` `new_string` exceeds ~20 lines, STOP and split it.
+- No diagnostic noise in production code. `sys.stderr.write(f"[XYZ_DIAG] ...")` lines added to `src/*.py` for debugging must be removed (not just left uncommitted) before the agent's work is "done." Diagnostic code that ships is technical debt. If you need to instrument for a one-time investigation, use a temporary file under `tests/artifacts/` or read the source with `get_file_slice` instead of polluting production.

+---
+
+## Process Anti-Patterns (Added 2026-06-09)
+
+These are the bad patterns the agents have been exhibiting that the user explicitly called out as dog-shit. The rules below are short. If you find yourself doing any of these, STOP and reread this section.
+
+### 1. The Deduction Loop (kill it)
+
+**Symptom:** Run test → fail → read log → form hypothesis → run again → fail differently → add diag → run again → fail again → loop. You end up running the same test 4+ times in one session, each run reading partial log output.
+
+**Rule:** You are allowed to run a failing test at most **2 times** in a single investigation. After the 2nd failure, STOP running the test. Read the relevant source code (`get_file_slice` or `py_get_skeleton`), predict the failure mode from the code, and instrument ALL the relevant state in one pass before the next run. If the test still fails after 1 instrumented run, report to the user — do not loop.
+
+**Worst case captured upfront.** Before running the test, ask: "what is the worst-case information I will need if this fails?" Add the diag for that, then run. The diag lines themselves are wasteful in production — see "No Diagnostic Noise in Production" below.
+
+### 2. The Report-Instead-of-Fix Pattern (kill it)
+
+**Symptom:** You can't fix the bug. You write a 200-line status report explaining why you can't fix it. The report contains "What I tried this session", "What I am NOT going to do", "What you can do", and "Files changed in this session (cumulative)." The report is a confession, not a fix.
+
+**Rule:** A status report is allowed only when:
+- You have actually tried the fix and it failed with evidence, OR
+- You are blocked on a decision the user must make.
+
+A status report is NOT allowed when:
+- You are avoiding a hard problem by writing prose about it.
+- The user asked for a fix and you have not yet tried.
+- The "what you can do" section is a list of options to defer to the user instead of picking the best one and doing it.
+
+A good status report is 5-10 sentences, not 200 lines.
+
+### 3. The Scope-Creep Track-Doc Pattern (kill it)
+
+**Symptom:** The user asks for a 1-line fix. You write a 5-phase "future track" spec with 140 lines of scope, audit findings, recommendations, and "out of scope" sections. The track doc is now larger than the fix it was meant to scope.
+
+**Rule:** If the user asks for a fix, your output is the fix. A track doc is only appropriate when the fix is multi-day work that requires a plan. If the fix is < 100 lines, it does not get a track. If the fix would touch more than 5 files, it MIGHT get a track — but ask first.
+
+### 4. The Inherited-Cruft Pattern (kill it)
+
+**Symptom:** The previous agent left a half-finished refactor in the working tree. The file is broken. You try to fix it and make it worse. You try again. You make it worse. The file stays broken for 3 days.
+
+**Rule:** If the file is already in a broken state from a previous session, the FIRST thing you do is ask the user: "this file is in a broken state from a previous agent. do you want me to (a) revert the working tree and start from a clean baseline, (b) finish the previous agent's intent, or (c) abandon the work entirely?" You do not start by "trying to fix" the broken file. The user's answer determines the work, not your assumption.
+
+### 5. No Diagnostic Noise in Production (kill it)
+
+**Symptom:** You add `sys.stderr.write(f"[RAG_DIAG] ...)")` to `src/rag_engine.py` and `src/app_controller.py` to debug a test failure. The diag lines help. You "revert everything" but leave the 4-8 diag lines in the working tree uncommitted. The next agent runs `git status`, sees the diag lines, and either commits them by accident or spends 10 minutes cleaning them up.
+
+**Rule:** Diagnostic stderr goes to a log file (`tests/artifacts/<test_name>.diag.log`) or to a temporary diagnostic script (`/tmp/diag_rag.py`), NOT to `src/*.py`. If you absolutely must instrument a production function for a single test run, the diag lines are part of the same atomic commit as the fix — they do not live uncommitted in the working tree. If you "revert everything," that means the diag lines are also reverted.
+
+### 6. The "I Am Not Going To Attempt Another Fix Without Your Direction" Surrender (kill it)
+
+**Symptom:** You've tried 3 things. None worked. You write: "I am not going to attempt another fix without your direction." Then you wait for the user to tell you what to do.
+
+**Rule:** This is correct ONLY if you have already done the things below:
+- Read the actual source code, not from memory
+- Predicted the failure mode from the code
+- Instrumented the relevant state in one pass
+- Run the test once with instrumentation
+- Captured the full output, not partial output
+
+If you have done all 5 and are still stuck, surrendering is fine. If you have not, you are surrendering too early. The user does not want to be your strategist; the user wants the agent to make progress.
+
+### 7. The Verbose-Commit-Message Pattern (kill it)
+
+**Symptom:** Your commit message is 50 lines. It contains the root cause analysis, the alternatives you considered, the side effects you considered, the cross-references, the "what this doesn't fix", the "what to verify", and a personal essay. The commit message is longer than the diff it describes.
+
+**Rule:** A commit message is a 1-3 sentence summary. The body is for non-obvious "why" details, not for re-stating what the diff shows. If your commit message is longer than 15 lines, you are writing a report, not a commit message. Save the report for `docs/reports/`.
+
+### 8. The "Isolated Pass" Verification Fallacy (kill it)
+
+**Symptom:** You run the test in isolation. It passes. You commit. The test fails in batch. You didn't notice because you never ran the batch.
+
+**Rule:** For any `live_gui` test or any test that depends on shared subprocess state, the **only verification that matters is the batch run**. A test that passes in isolation but fails in batch is failing — it's just that the failure is masked by isolation. Per the existing `Live_gui Test Fragility` rule in `conductor/workflow.md`: "Bisect failures by running the test both in the full suite and in isolation to distinguish 'test needs work' from 'real app bug'." If you only ever run in isolation, you cannot tell the difference.

+# `mma_tier_usage` Reset Fix — Implementation Plan
+
+> **For Tier 3 workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+>
+> **Scope is exactly 4 surgical edits in `src/app_controller.py` + 2 new regression tests. Do not refactor anything else. Do not add new tests beyond the 2 in this plan. Do not update docs. Do not file follow-up tracks. Execute exactly what is here, then stop.**
+
+**Goal:** Fix 3 pre-existing bugs in `src/app_controller.py` that surface during the test suite:
+- **FR1+FR2:** Restore the pre-`fe240db4` contract that `_flush_to_project` requires (every `mma_tier_usage[tier]` entry has a `model` key), and harden `_flush_to_project` so it does not crash if a future code path produces a partial entry.
+- **FR3:** Re-add the `self.context_preset_manager = ContextPresetManager()` init line that was lost in `72f8f466`. Without it, `save_context_preset` and `load_context_preset` crash.
+- **FR4:** Remove `persona_manager` from `_LAZY_MANAGER_DEFAULTS` in `__getattr__` (the comment is wrong; `__getattr__` returning None makes `hasattr()` return True, breaking `test_load_active_project_creates_persona_manager`).
+
+**Architecture:** Four surgical edits in `src/app_controller.py`. No new modules, no new helpers, no API changes.
+
+**Tech Stack:** Python 3.11+, pytest.
+
+**HARD CONSTRAINTS (from `AGENTS.md` and `conductor/edit_workflow.md`):**
+- **NEVER** use `git checkout -- <file>`, `git restore`, `git reset`, or any other form of pre-fix replay (including scratch reproduction scripts that simulate the pre-fix state). The user explicitly banned all of these. They destroyed user in-progress work twice. Step 3.1.4 is intentionally a no-op; the 3rd regression test's docstring explains the pre-fix failure mode in prose as a substitute.
+- **1-space indent, CRLF, type hints.** Per project conventions.

+  ```
+
+---
+
+## Phase 1: Apply FR1 (pre-populate `mma_tier_usage` on reset)
+
+Focus: Restore the pre-`fe240db4` shape of `mma_tier_usage` in `_handle_reset_session`.
+
+### Task 1.1: Read the current state of `_handle_reset_session`
+
+- [ ] **Step 1.1.1: Read the exact lines**
+  Use `manual-slop_get_file_slice` to read `src/app_controller.py:3407-3411`. Confirm the current shape is `{'Tier 1': {}, 'Tier 2': {}, 'Tier 3': {}, 'Tier 4': {}}` (empty dicts) on line 3409, with the comment `# Reset mma_tier_usage to pre-populated default (prior tests pollute it)` on line 3408.
+
+### Task 1.2: Apply the edit
+
+**Files:**
+- Modify: `src/app_controller.py:3409` (the empty-dict reset)
+
+- [ ] **Step 1.2.1: Replace the empty-dict reset with the pre-populated default**
+
+  Change FROM:
+  ```python
+  # Reset mma_tier_usage to pre-populated default (prior tests pollute it)
+  self.mma_tier_usage = {'Tier 1': {}, 'Tier 2': {}, 'Tier 3': {}, 'Tier 4': {}}
+  ```
+
+  Change TO:
+  ```python
+  # Reset mma_tier_usage to the same shape as __init__ (line 952-957). Prior
+  # tests pollute it; downstream consumers like _flush_to_project require
+  # every tier entry to have 'model' / 'provider' / 'tool_preset' keys. The
+  # pre-populated defaults (input=0, output=0, provider='gemini', model=
+  # tier default, tool_preset=None) restore the contract without retaining
+  # any polluted model names or token counts from a prior session.
+  self.mma_tier_usage = {
+   "Tier 1": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-3.1-pro-preview", "tool_preset": None},
+   "Tier 2": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-3-flash-preview", "tool_preset": None},
+   "Tier 3": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-2.5-flash-lite",  "tool_preset": None},
+   "Tier 4": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-2.5-flash-lite",  "tool_preset": None},
+  }
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact start_line and end_line of the block. Verify the slice boundaries with `manual-slop_get_file_slice` first.
+
+  **CRITICAL — 1-space indent.** The dict values (the per-tier dicts) use 1-space indent. The outer dict has no indent. Match the existing project convention exactly.
+
+  **CRITICAL — Do NOT use empty dicts.** Empty dicts cause the test to fail. The whole point of this fix is to pre-populate.
+

The empty-dict reset broke _flush_to_project at line 2639, which does d['model'] and raised KeyError. The crash then caused _do_project_switch's finally block to re-queue the switch infinitely, which is why test_context_sim_live saw the 'switching to: temp_livecontextsim (stale ui - ops disabled)' status for 60+ seconds. 1 file changed, ~10 lines." $h
+  ```
+

+
+## Phase 2: Apply FR2 (defensive `_flush_to_project`)
+
+Focus: Make `_flush_to_project` not crash if a future code path produces a partial `mma_tier_usage[tier]` entry.
+
+### Task 2.1: Read the current state of `_flush_to_project`
+
+- [ ] **Step 2.1.1: Read the exact line**
+  Use `manual-slop_get_file_slice` to read `src/app_controller.py:2638-2640`. Confirm line 2639 is:
+  ```python
+  mma_sec["tier_models"] = {t: {"model": d["model"], "provider": d.get("provider", "gemini"), "tool_preset": d.get("tool_preset")} for t, d in self.mma_tier_usage.items()}

+
+### Task 2.2: Apply the edit
+
+**Files:**
+- Modify: `src/app_controller.py:2639`
+
+- [ ] **Step 2.2.1: Replace `d["model"]` with `d.get("model")`**
+
+  Change FROM:
+  ```python
+  mma_sec["tier_models"] = {t: {"model": d["model"], "provider": d.get("provider", "gemini"), "tool_preset": d.get("tool_preset")} for t, d in self.mma_tier_usage.items()}
+  ```
+
+  Change TO:
+  ```python
+  mma_sec["tier_models"] = {t: {"model": d.get("model"), "provider": d.get("provider", "gemini"), "tool_preset": d.get("tool_preset")} for t, d in self.mma_tier_usage.items()}
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact start_line and end_line.
+
+  **CRITICAL — Do not change `d.get("provider", ...)` or `d.get("tool_preset")`.** Only `d["model"]` becomes `d.get("model")`.
+
+- [ ] **Step 2.2.2: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('src/app_controller.py').read()); print('OK')"
+  ```

+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "from src.app_controller import AppController; print('import OK')"
+  ```
+
+### Task 2.3: Commit FR2
+
+- [x] **Step 2.3.1: Commit the FR2 change** (commit 1919aa8a)
+  ```powershell
+  cd C:\projects\manual_slop; git add src/app_controller.py
+  git commit -m "fix(controller): _flush_to_project defensive against missing 'model' key"
+  $h = git log -1 --format='%H'
+  git notes add -m "Defense in depth. d['model'] is replaced with d.get('model') so a future code path that produces a partial mma_tier_usage[tier] dict (e.g. _handle_mma_state_update at line 484-497 does controller.mma_tier_usage[tier] = data) doesn't crash the project save. The other .get() calls (provider, tool_preset) were already defensive; this aligns the model lookup. 1 file changed, 1 line." $h
+  ```
+
+---
+
+## Phase 3: Apply FR3 (re-add `context_preset_manager` init)
+
+Focus: Restore the `self.context_preset_manager = ContextPresetManager()` init line that was lost in `72f8f466`.
+
+### Task 3.1: Read the current state of `__init__`
+
+- [ ] **Step 3.1.1: Read the exact lines around the insertion point**
+  Use `manual-slop_get_file_slice` to read `src/app_controller.py:1182-1186`. Confirm the current shape is:
+  ```python
+    })
+   self.perf_monitor            = performance_monitor.get_monitor()
+  ```
+
+### Task 3.2: Apply the edit
+
+**Files:**
+- Modify: `src/app_controller.py` (insert one line between line 1183 and 1185)
+
+- [ ] **Step 3.2.1: Insert the `context_preset_manager` init**
+
+  Change FROM:
+  ```python
+    })

+   self.context_preset_manager  = ContextPresetManager()
+   self.perf_monitor            = performance_monitor.get_monitor()
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact start_line and end_line of the 2-line block (the `})` close brace and the `self.perf_monitor` line). Replace with the 3-line block above.
+
+  **CRITICAL — Use exactly 1-space indent.** The `})` line has no indent (it's a closing brace at the module level). The new `self.context_preset_manager` line has 1 space. The `self.perf_monitor` line has 1 space. Match the surrounding style exactly.
+
+  **CRITICAL — Use the exact same spacing and double-space alignment** as the `c039fdbb` version: `self.context_preset_manager  = ContextPresetManager()` (2 spaces before the `=`). The 2-space alignment matches the `self.perf_monitor            = ...` and `self._perf_profiling_enabled = ...` lines around it.
+
+- [ ] **Step 3.2.2: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('src/app_controller.py').read()); print('OK')"
+  ```

+  cd C:\projects\manual_slop; uv run python -c "from src.app_controller import AppController; ctrl = AppController(); print('context_preset_manager:', type(ctrl.context_preset_manager).__name__)"
+  ```
+  Expected output: `context_preset_manager: ContextPresetManager`
+
+- [ ] **Step 3.2.4: Verify `hasattr` semantics on a bare AppController**
+  The bug we're fixing requires `context_preset_manager` to be set so `save_context_preset` and `load_context_preset` work. But we still want `__getattr__` to handle OTHER missing attrs. Verify with:
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "from src.app_controller import AppController; ctrl = AppController(); print('has context_preset_manager:', hasattr(ctrl, 'context_preset_manager'))"
+  ```
+  Expected: `has context_preset_manager: True`
+
+### Task 3.3: Commit FR3
+
+- [x] **Step 3.3.1: Commit the FR3 change** (commit bc4651d1)
+  ```powershell
+  cd C:\projects\manual_slop; git add src/app_controller.py
+  git commit -m "fix(controller): re-add self.context_preset_manager init (lost in 72f8f466)"
+  $h = git log -1 --format='%H'
+  git notes add -m "Re-adds the self.context_preset_manager = ContextPresetManager() line that was in c039fdbb but accidentally dropped during a hand-edited refactor of the _settable_fields block in 72f8f466. Without this init, save_context_preset and load_context_preset crash with AttributeError: 'NoneType' object has no attribute 'save_preset' (or 'load_all'). The ContextPresetManager import was already at the top of the file (line 41), so no new import is needed. 1 file changed, 1 line." $h
+  ```
+
+---
+
+## Phase 4: Apply FR4 (remove `persona_manager` from `_LAZY_MANAGER_DEFAULTS`)
+
+Focus: Make `hasattr(ctrl, "persona_manager")` return False for a fresh `AppController()` so the regression test `test_load_active_project_creates_persona_manager` passes.
+
+### Task 4.1: Read the current state of `_LAZY_MANAGER_DEFAULTS`
+
+- [ ] **Step 4.1.1: Read the exact lines**
+  Use `manual-slop_get_file_slice` to read `src/app_controller.py:1260-1281`. Confirm the current shape is:
+  ```python
+  _LAZY_MANAGER_DEFAULTS = {
+   "context_preset_manager",
+    "persona_manager",
+    "tool_preset_manager",
+    "preset_manager",
+    "vendor_state",
+    "perf_monitor",
+   }
+  ```
+
+### Task 4.2: Apply the edit
+
+**Files:**
+- Modify: `src/app_controller.py:1267` (the `"persona_manager"` line in `_LAZY_MANAGER_DEFAULTS`)
+
+- [ ] **Step 4.2.1: Remove `"persona_manager"` from the set**
+
+  Change FROM:
+  ```python
+  _LAZY_MANAGER_DEFAULTS = {
+   "context_preset_manager",
+    "persona_manager",
+    "tool_preset_manager",
+    "preset_manager",
+    "vendor_state",
+    "perf_monitor",
+   }
+  ```
+
+  Change TO:
+  ```python
+  _LAZY_MANAGER_DEFAULTS = {
+   "context_preset_manager",
+    "tool_preset_manager",
+    "preset_manager",
+    "vendor_state",
+    "perf_monitor",
+   }
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact start_line and end_line of the block.
+
+  **CRITICAL — Keep the other 5 names.** Only `"persona_manager"` is removed in this FR. The other 5 may have lazy-default callers that need verification in the batch run. Removing them is a follow-up.
+
+- [ ] **Step 4.2.2: Update the misleading comment above the set**
+
+  Change FROM:
+  ```python
+  # Manager attributes that are initialized by init_state() but are absent
+  # on a bare AppController() (which some tests construct). Return None
+  # for these so test code that references them without calling init_state
+  # does not crash. hasattr() still returns False for non-mocked access
+  # paths because callers wrap in try/except for AttributeError when they
+  # need to distinguish "lazy" from "absent".
+  ```
+
+  Change TO:
+  ```python
+  # Manager attributes that are initialized by init_state() but are absent
+  # on a bare AppController() (which some tests construct). Return None
+  # for these so test code that references them without calling init_state
+  # does not crash. NOTE: callers that need to distinguish "lazy" from
+  # "absent" must use try/except AttributeError explicitly; hasattr()
+  # returns True because __getattr__ returns None (a valid attribute
+  # value).
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact start_line and end_line of the comment block.
+
+- [ ] **Step 4.2.3: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('src/app_controller.py').read()); print('OK')"
+  ```
+
+- [ ] **Step 4.2.4: Verify the import is still valid**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "from src.app_controller import AppController; ctrl = AppController(); print('has persona_manager:', hasattr(ctrl, 'persona_manager'))"
+  ```
+  Expected: `has persona_manager: False`
+
+- [ ] **Step 4.2.5: Verify `_load_active_project` still sets `persona_manager`**
+  The fix only changes `__getattr__` behavior for missing attrs. After `_load_active_project()` is called, `persona_manager` should be a real `PersonaManager` instance.
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "from src.app_controller import AppController; ctrl = AppController(); ctrl.active_project_path = 'tests/artifacts/temp_livecontextsim.toml'; ctrl._load_active_project(); print('has persona_manager after load:', hasattr(ctrl, 'persona_manager')); print('type:', type(ctrl.persona_manager).__name__)"
+  ```
+  Expected: `has persona_manager after load: True` and `type: PersonaManager` (or similar — the test only requires `hasattr` to be True after `_load_active_project`).
+
+  If the actual `temp_livecontextsim.toml` file doesn't exist, that's OK — `_load_active_project` may log a warning but should still set `persona_manager`. If the test fails because the file doesn't exist, skip this verification step.
+
+### Task 4.3: Commit FR4
+
+- [x] **Step 4.3.1: Commit the FR4 change** (commit 4284ec6e)
+  ```powershell
+  cd C:\projects\manual_slop; git add src/app_controller.py
+  git commit -m "fix(controller): remove 'persona_manager' from _LAZY_MANAGER_DEFAULTS"
+  $h = git log -1 --format='%H'
+  git notes add -m "Removes 'persona_manager' from the _LAZY_MANAGER_DEFAULTS set in __getattr__. The original code returned None for these attrs, but the accompanying comment claimed hasattr() returns False (which is wrong — __getattr__ returning None makes hasattr() return True). The test test_load_active_project_creates_persona_manager asserts not hasattr(ctrl, 'persona_manager') for a fresh controller, which is the correct Python semantics. The other 5 names in the set are kept; they may have lazy-default callers that need verification in the batch run. 1 file changed, comment + 1 line." $h
+  ```
+

+
+## Phase 5: Add 4 regression tests
+
+Focus: Unit tests that prove the fixes prevent the original failures. Two for FR1+FR2 (post-reset flush), one for FR3 (context_preset_manager is callable), one for FR4 (persona_manager hasattr semantics).
+
+### Task 5.1: Write the regression tests
+
+**Files:**
+- Create: `tests/test_mma_tier_usage_reset_fix.py`

+  If you want extra confidence the test design is correct, READ the test, READ the bug location (lines 3409, 1183, 1267 in the current HEAD), and PREDICT the failure mode from the code. Do not run it against pre-fix state.

+## Phase 6: Run the full batch and verify
+
+Focus: The moment of truth. The 4 sim tests in `test_extended_sims.py` now pass, the 3 previously-failing tier-1 tests now pass, Tier-2 still passes, no new tier-3 failures.
+
+### Task 6.1: Verify the existing 3 tests in `test_reset_session_clears_mma_and_rag.py` still pass
+
+- [ ] **Step 6.1.1: Run the regression tests from `fe240db4`**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_reset_session_clears_mma_and_rag.py -v --timeout=60
+  ```
+  Expected: 3/3 pass (the `fe240db4` regressions are not broken by the new fix).
+
+### Task 6.2: Run the 3 previously-failing tier-1 tests + 4 sim tests
+
+- [ ] **Step 6.2.1: Run the 3 previously-failing tier-1 tests**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_context_presets_manager.py::test_app_controller_save_load tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror -v --timeout=60
+  ```
+  Expected: 3/3 pass.
+
+- [ ] **Step 6.2.2: Run the 4 sim tests**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_extended_sims.py -v --timeout=300
+  ```
+  Expected: 4/4 pass. **CRITICAL: This must be in batch mode** (i.e. as part of a larger run, not isolation). If the test is run in isolation, it may pass even without the fix because the io_pool is empty. Verify the run is the FULL pytest invocation of `test_extended_sims.py` (all 4 tests share a live_gui subprocess).
+
+### Task 6.3: Run the full batch
+
+- [ ] **Step 6.3.1: Run the full batched test suite**
+  ```powershell
+  cd C:\projects\manual_slop; uv run .\scripts\run_tests_batched.py 2>&1 | Tee-Object -FilePath "tests/artifacts/post_mma_reset_fix_batch_20260610.log" | Select-Object -Last 50
+  ```
+  Expected:
+  - tier-1: 5/5 batches pass
+  - tier-2: 5/5 batches pass
+  - tier-3: 0 NEW failures vs the `33d02bb1` baseline (i.e. the 4 sim tests now pass; the 3 `fe240db4` regression tests still pass)
+
+- [ ] **Step 6.3.2: If tier-3 has new failures, STOP and report**
+  **DO NOT** try to fix new failures in this track. This track's scope is the 4 FRs above. New failures are out of scope — document them in the git note and move on.
+
+### Task 6.4: Checkpoint commit
+
+- [x] **Step 6.4.1: Create the checkpoint commit** (commit 428aa189)
+  ```powershell
+  cd C:\projects\manual_slop; git add tests/artifacts/post_mma_reset_fix_batch_20260610.log
+  git commit -m "conductor(checkpoint): Checkpoint end of Phase 6 (4 FRs + 4 regression tests)"
+  $h = git log -1 --format='%H'
+  git notes add -m "Final batch run log. tier-1 5/5, tier-2 5/5, tier-3 [count] failures (should be 0 new vs 33d02bb1). The 4 sim tests in test_extended_sims.py now pass because FR1+FR2 fix the mma_tier_usage reset. The 3 previously-failing tier-1 tests now pass because FR3 re-adds the context_preset_manager init and FR4 removes persona_manager from _LAZY_MANAGER_DEFAULTS." $h
+  ```
+
+---
+
+## Final Verification
+
+- [x] All 5 commits in place (FR1, FR2, FR3, FR4, regression tests, checkpoint)
+- [x] `src/app_controller.py:3409` pre-populates `mma_tier_usage` with the full default shape
+- [x] `src/app_controller.py:2639` uses `d.get("model")` instead of `d["model"]`
+- [x] `src/app_controller.py:__init__` contains `self.context_preset_manager = ContextPresetManager()`
+- [x] `src/app_controller.py:1266-1275` does NOT contain `"persona_manager"` in `_LAZY_MANAGER_DEFAULTS`
+- [x] 4 new regression tests in `tests/test_mma_tier_usage_reset_fix.py` pass
+- [x] 3 existing tests in `tests/test_reset_session_clears_mma_and_rag.py` still pass
+- [x] 3 previously-failing tier-1 tests now pass:
+  - `tests/test_context_presets_manager.py::test_app_controller_save_load`
+  - `tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager`
+  - `tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror`
+- [x] 4 sim tests in `tests/test_extended_sims.py` pass (ISOLATED run; 4/4 in 222.08s)
+- [x] Targeted regression verification: 36/36 affected tests pass
+- [x] Tier-1 batch: 5/5 pass (2026-06-10 batch run)
+- [x] Tier-2 batch: 5/5 pass (2026-06-10 batch run)
+- [ ] Tier-3 batch: 0 new failures (FAILED in 2026-06-10 batch run; see Phase 2 below)
+
+## Phase 2: Fix live_gui sim test fragility
+
+The Phase 1 verification (isolated sim test run) was misleading. The full batch run revealed a SEPARATE failure in `test_extended_sims.py::test_context_sim_live` — `KeyError: 'paths'` at `simulation/sim_context.py:44`. This is a live_gui shared-subprocess state issue, not a regression of the FR1+FR2 fix.
+
+### Task 7.1: Diagnose the root cause
+
+- [ ] **Step 7.1.1: Read the duplicated loop in sim_context.py**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; print(ast.unparse(ast.parse(open('simulation/sim_context.py').read())))" | Select-String "for f in all_py"
+  ```
+  Confirm lines 32-37 and 41-47 are duplicate logic. The second loop is supposed to add MORE files but the first loop already added all of them.
+
+- [ ] **Step 7.1.2: Check what post_project does to empty/missing `paths`**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "
+from api_hook_client import ApiHookClient
+import json
+client = ApiHookClient()
+import time
+if not client.wait_for_server(timeout=5):
+    print('server not up; skip')
+else:
+    p = client.get_project()
+    print('project files before:', json.dumps(p.get('project', {}).get('files', {}), indent=2))
+  "
+  ```
+  Expected: in the live_gui subprocess, the project's `files` dict may not have a `paths` key after a fresh `setup()` (because the test setup at `simulation/sim_base.py:78-99` doesn't pre-populate `paths`).
+
+- [ ] **Step 7.1.3: Read sim_base.setup to understand initial state**
+  Use `manual-slop_get_file_slice` to read `simulation/sim_base.py:78-99`. Confirm `setup()` does NOT pre-populate `files['paths']` in the saved project.
+
+### Task 7.2: Apply the fix
+
+The fix is a 1-3 line change. Choose ONE of:
+
+**Option A: Make the test code defensive (test-only fix)**
+Modify `simulation/sim_context.py:44` to use `.setdefault('paths', [])`:
+```python
+for f in all_py:
+    if f not in proj['project']['files'].setdefault('paths', []):
+        proj['project']['files']['paths'].append(f)
+```
+Apply to BOTH loops (lines 33-35 and lines 43-45) for consistency.
+
+**Option B: Remove the redundant second loop (cleanup)**
+The second loop (lines 41-47) is identical to the first. Remove it. The first loop's `post_project` (line 37) already saves the project with all the files. The second loop+post is unnecessary.
+
+**Recommended:** Option A is the minimal, defensive fix that addresses the test fragility without restructuring. Option B is cleaner code but more change.
+
+- [ ] **Step 7.2.1: Apply the chosen fix to simulation/sim_context.py**
+
+- [ ] **Step 7.2.2: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('simulation/sim_context.py').read()); print('OK')"
+  ```
+
+- [ ] **Step 7.2.3: Verify import**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "from simulation.sim_context import ContextSimulation; print('import OK')"
+  ```
+
+### Task 7.3: Verify in batch
+
+- [ ] **Step 7.3.1: Run the 4 sim tests in isolation first (sanity)**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_extended_sims.py -v --timeout=300
+  ```
+  Expected: 4/4 pass in isolation.
+
+- [ ] **Step 7.3.2: Run the FULL batch to confirm (authoritative verification)**
+  ```powershell
+  cd C:\projects\manual_slop; uv run .\scripts\run_tests_batched.py 2>&1 | Tee-Object -FilePath "tests/artifacts/post_phase2_mma_reset_fix_batch_20260610.log" | Select-Object -Last 50
+  ```
+  Expected: tier-1 5/5, tier-2 5/5, tier-3 0 failures.
+
+### Task 7.4: Final checkpoint
+
+- [ ] **Step 7.4.1: Commit the fix**
+  ```powershell
+  cd C:\projects\manual_slop; git add simulation/sim_context.py
+  git commit -m "fix(sim): make test_context_sim_live defensive against missing files['paths'] in batch"
+  $h = git log -1 --format='%H'
+  git notes add -m "..." $h
+  ```
+
+- [ ] **Step 7.4.2: Checkpoint commit with full batch log**
+  ```powershell
+  cd C:\projects\manual_slop; git add -f tests/artifacts/post_phase2_mma_reset_fix_batch_20260610.log
+  git commit -m "conductor(checkpoint): Phase 2 complete - sim test fragility fixed"
+  $h = git log -1 --format='%H'
+  git notes add -m "..." $h
+  ```
+
+## Track Done

+- File follow-up tracks
+- Add scope

+# Track Specification: Fix `mma_tier_usage` reset breaking `_flush_to_project` + 2 pre-existing bugs (2026-06-10)
+
+## Overview
+
+This track fixes **3 distinct pre-existing bugs** in `src/app_controller.py` that surfaced during the 2026-06-10 batch run:
+
+1. **`mma_tier_usage` reset to empty dicts** (introduced in `fe240db4` 2026-06-09). `_handle_reset_session` zeroes the per-tier dicts to `{}`, but `_flush_to_project` does `d["model"]` and crashes with `KeyError`. This crashes the project save AND triggers an infinite re-switch loop in `_do_project_switch`'s finally block. Symptom: `test_context_sim_live` sees `ai_status = "error: 'model'"` (or "switching to: ... (stale ui - ops disabled)" in older runs) and times out at 60s.
+
+2. **`self.context_preset_manager` is never initialized in `__init__`** (accidentally lost in `72f8f466` 2026-06-10). The line `self.context_preset_manager = ContextPresetManager()` was in the codebase at `c039fdbb` (2026-06-09) and got dropped when `_settable_fields` block was hand-edited. `save_context_preset` and `load_context_preset` both dereference `self.context_preset_manager.save_preset(...)` and `self.context_preset_manager.load_all(...)` — both crash with `AttributeError: 'NoneType' object has no attribute 'save_preset'` (or `'load_all'`). Symptom: `tests/test_context_presets_manager.py::test_app_controller_save_load` and `tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror` fail in tier-1.
+
+3. **`__getattr__` short-circuits manager attributes to None, breaking `hasattr()`** (added 2026-06-08 in `c039fdbb`'s neighborhood). The `_LAZY_MANAGER_DEFAULTS` set in `AppController.__getattr__` (src/app_controller.py:1266-1275) returns `None` for `context_preset_manager`, `persona_manager`, `tool_preset_manager`, `preset_manager`, `vendor_state`, `perf_monitor`. The code comment claims "hasattr() still returns False for non-mocked access paths" but this is wrong — `__getattr__` returning None makes `hasattr()` return True. Symptom: `tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager` fails because it asserts `not hasattr(ctrl, "persona_manager")` for a fresh `AppController()`, but `__getattr__` returns None so `hasattr()` returns True.
+
+The mma_tier_usage fix was the original ask. The 2 additional bugs surfaced when the user ran the full batch to verify the original fix. Including all 3 in this track is in-scope: they are all in the same file (`src/app_controller.py`), all pre-existing (not introduced by my changes), all block the test suite from going green, and all are 1-3 line surgical fixes.
+
+## Bug 1 in detail: `mma_tier_usage` reset
+
+`_handle_reset_session` (src/app_controller.py:3358) was changed in commit `fe240db4` to reset `mma_tier_usage` to `{'Tier 1': {}, 'Tier 2': {}, 'Tier 3': {}, 'Tier 4': {}}` — empty dicts. The downstream consumer `_flush_to_project` (line 2639) does `d["model"]` and crashes with `KeyError: 'model'` when iterating over the per-tier dicts.
+
+This is the root cause of `test_context_sim_live` (and the 3 sibling sims) failing. The test sees the `ai_status` of `"error: 'model'"` (after the sim_context.py polling loop added an `"error" in s` check) because:
+
+1. The test clicks `btn_reset` → `_handle_reset_session` zeroes `mma_tier_usage` to empty dicts.
+2. The test clicks `btn_project_new_automated` → `_switch_project(path)` is called → sets `in_progress=True`, submits `_do_project_switch` to the io_pool, sets `ai_status = "switching to: ... (stale ui - ops disabled)"`.
+3. The test clicks `btn_project_save` → `_cb_project_save` calls `_flush_to_project()` on the main render thread → CRASHES with `KeyError: 'model'`. The exception is silently swallowed by `_process_pending_gui_tasks`'s try/except.
+4. **Concurrently** on the io_pool: `_do_project_switch` runs → calls `self._flush_to_project()` FIRST → CRASHES with the same `KeyError` → `finally` block runs → `in_progress=False` → `pending == active_project_path` is false (we never got to update `active_project_path`) → `_switch_project(pending)` is called recursively → resubmits → `in_progress=True` again → `_do_project_switch` crashes again → infinite re-switch loop.
+5. After 60+ seconds of the re-switch loop, eventually some other worker call reaches `_handle_md_only` (the test's actual target). It crashes the same way, but the `except Exception as e: self.ai_status = f"error: {e}"` in `_handle_md_only`'s worker (line 3560) catches it and sets `ai_status = "error: 'model'"`.
+6. Test polls `ai_status` and sees `"error: 'model'"`. The `"error" in s` branch in the sim polling loop (added to `sim_context.py` in the working tree) breaks early. The assertion fails with the message: `Expected 'md written' in status, got error: 'model'`.
+
+The fix restores the pre-`fe240db4` behavior of `_handle_reset_session`: pre-populate `mma_tier_usage` with the full default values (input, output, provider, model, tool_preset) so that downstream consumers like `_flush_to_project` don't crash on missing keys.
+
+The 3 regression tests in `tests/test_reset_session_clears_mma_and_rag.py` (added in the same `fe240db4` commit) check that the polluted `'model' = 'polluted'` value is cleared. They pass with the pre-populated defaults because `'gemini-3.1-pro-preview' != 'polluted'`. The goal of "no stale pollution" is preserved.
+
+## Bug 2 in detail: missing `context_preset_manager` init
+
+`git show c039fdbb:src/app_controller.py` shows the line was present at that commit:
+```python
+self.context_preset_manager  = ContextPresetManager()
+```
+right after the `_settable_fields` block and before `self.perf_monitor = ...`. `git show HEAD:src/app_controller.py` (after `72f8f466`) shows the line is gone. The diff between `c039fdbb` and `72f8f466` confirms it was the one line dropped:
+```
+-self.context_preset_manager  = ContextPresetManager()
+```
+during a hand-edited refactor of the `_settable_fields` block.
+
+The fix is to re-add the line at the same position in `__init__`.
+
+## Bug 3 in detail: `__getattr__` returns None for manager attrs
+
+The `__getattr__` at src/app_controller.py:1226-1281 has a `_LAZY_MANAGER_DEFAULTS` set (lines 1266-1275) that includes `persona_manager`, `context_preset_manager`, `tool_preset_manager`, `preset_manager`, `vendor_state`, `perf_monitor`. When the controller is constructed without calling `init_state()` (some tests do this), accessing these attributes goes through `__getattr__` which returns `None`.
+
+The comment on the set says:
+> "hasattr() still returns False for non-mocked access paths because callers wrap in try/except for AttributeError when they need to distinguish 'lazy' from 'absent'."
+
+This is **wrong**. `__getattr__` returning `None` makes `hasattr(obj, name)` return `True` (because `None` is a valid attribute value). The test `test_load_active_project_creates_persona_manager` is written correctly per Python semantics — it asserts that before `_load_active_project()` is called, the controller should not have `persona_manager`. But because `__getattr__` returns `None`, `hasattr(ctrl, "persona_manager")` is `True`, and the assertion fails.
+
+The fix: remove `persona_manager` (and the other lazily-managed attrs) from `_LAZY_MANAGER_DEFAULTS`, so `__getattr__` raises `AttributeError` for them. Callers that want the lazy default can use `getattr(ctrl, "persona_manager", None)`. The comment should also be removed or updated to reflect the actual Python semantics.
+
+`context_preset_manager` is also in this set, so removing it from `_LAZY_MANAGER_DEFAULTS` is necessary regardless (Bug 2's fix re-adds the init, so the lazy fallback is no longer needed for that one). For the other 5 names (`persona_manager`, `tool_preset_manager`, `preset_manager`, `vendor_state`, `perf_monitor`), the lazy fallback may or may not be load-bearing for other tests. The conservative fix is to remove `persona_manager` specifically (the one the test asserts on) and verify the other 5 don't have callers relying on the lazy default.
+
+Actually, looking at the test that's failing more carefully:
+- `test_load_active_project_creates_persona_manager` only asserts `not hasattr(ctrl, "persona_manager")` BEFORE `_load_active_project()`.
+- The test in the same file `test_switch_project_preserves_global_preset` (line 150) explicitly sets `ctrl.persona_manager = PersonaManager(...)` BEFORE calling `_refresh_from_project()`. This works fine because `setattr` doesn't go through `__getattr__`.
+- The test in the same file `test_load_context_preset_missing_raises_keyerror` (line 181) doesn't touch `persona_manager`.
+
+The minimal fix is to remove `persona_manager` from `_LAZY_MANAGER_DEFAULTS`. The other 5 names can stay (they have similar semantics; whether other tests depend on the lazy default needs to be verified in the batch run). The track will verify no regressions in the batch.
+
+## Current State Audit (as of `33d02bb1`)
+
+### Already Implemented (DO NOT re-implement)
+
+- `_handle_reset_session` (src/app_controller.py:3358) clears project state, MMA state, RAG state. Pre-populated `mma_tier_usage` defaults in `__init__` (line 952-957). 3 regression tests in `tests/test_reset_session_clears_mma_and_rag.py` verify the polluted state is cleared.
+- `simulation/sim_base.py` `setup()` (line 78-99) waits for the project switch to complete via `wait_for_project_switch(expected_path=..., timeout=30.0)`.
+- `simulation/sim_context.py` `run()` (line 17-30) waits for the project switch to complete again with `wait_for_project_switch(timeout=15.0)` before clicking `btn_md_only`. The polling loop also breaks early on `"error" in status` to surface terminal errors.
+- `src/api_hooks.py` exposes `/api/project_switch_status` (line 2493) and `/api/gui/state` (line 309). The latter is the fallback used by `get_project_switch_status` in `api_hook_client.py:362-384` when the dedicated endpoint is missing.
+- `src/app_controller.py:_switch_project` (line 2830) is non-blocking; submits `_do_project_switch` to `submit_io` (line 2303 → `_io_pool`).
+- `src/app_controller.py:_do_project_switch` (line 2789) is the async worker. Its `try`/`finally` structure (line 2792-2822) sets `in_progress = False` in the `finally` and recursively re-queues via `_switch_project(pending)` if `pending != active_project_path`. The recursion is the infinite loop when the worker fails before setting `active_project_path`.
+
+### Bugs
+
+**Bug 1: Empty `mma_tier_usage` reset.** `src/app_controller.py:3409` (introduced in commit `fe240db4`):
+
+```python
+# Reset mma_tier_usage to pre-populated default (prior tests pollute it)
+self.mma_tier_usage = {'Tier 1': {}, 'Tier 2': {}, 'Tier 3': {}, 'Tier 4': {}}
+```
+
+Comment says "pre-populated default" but the dicts are empty. `_flush_to_project` (line 2639) does:
+
+```python
+mma_sec["tier_models"] = {t: {"model": d["model"], "provider": d.get("provider", "gemini"), "tool_preset": d.get("tool_preset")} for t, d in self.mma_tier_usage.items()}
+```
+
+`d["model"]` raises `KeyError` when `d = {}`.
+
+**Bug 2: Missing `context_preset_manager` init.** `src/app_controller.py:__init__` does not set `self.context_preset_manager`. The line `self.context_preset_manager = ContextPresetManager()` was in the codebase at commit `c039fdbb` (2026-06-09) but was dropped during a hand-edited refactor in `72f8f466` (2026-06-10). `save_context_preset` and `load_context_preset` both dereference `self.context_preset_manager` which is `None` (via `__getattr__`'s `_LAZY_MANAGER_DEFAULTS` short-circuit, see Bug 3) — both crash with `AttributeError`.
+
+**Bug 3: `__getattr__` short-circuit breaks `hasattr()`.** `src/app_controller.py:1266-1281` has:
+
+```python
+_LAZY_MANAGER_DEFAULTS = {
+  "context_preset_manager",
+   "persona_manager",
+   "tool_preset_manager",
+   "preset_manager",
+   "vendor_state",
+   "perf_monitor",
+}
+if name in _LAZY_MANAGER_DEFAULTS:
+  return None
+```
+
+The accompanying comment claims `hasattr()` still returns False for these, which is **wrong** — `__getattr__` returning `None` makes `hasattr()` return `True`. Test `test_load_active_project_creates_persona_manager` asserts `not hasattr(ctrl, "persona_manager")` for a fresh controller and fails.
+
+### Gaps to Fill (This Track's Scope)
+
+- **Gap 1 (Bug 1): `_handle_reset_session` should pre-populate `mma_tier_usage` with the full default shape** (matching `__init__` at line 952-957), not empty dicts. This restores the pre-`fe240db4` contract that downstream consumers rely on.
+- **Gap 2 (Bug 1): `_flush_to_project` should be defensive** against missing `model` keys (use `.get("model", default)` instead of `["model"]`). Other code paths can produce partial `mma_tier_usage` entries (e.g. `_handle_mma_state_update` at line 484-497 does `controller.mma_tier_usage[tier] = data` with whatever data the caller sends). Defense in depth.
+- **Gap 3 (Bug 2): Re-add `self.context_preset_manager = ContextPresetManager()` in `__init__`** at the original position (after the `_settable_fields` block, before `self.perf_monitor = ...`).
+- **Gap 4 (Bug 3): Remove `persona_manager` from `_LAZY_MANAGER_DEFAULTS`** in `__getattr__`. The other 5 names stay (they may have lazy-default callers; verify in batch). Also fix or remove the misleading comment.
+
+## Goals
+
+1. **Goal A: `test_context_sim_live` passes in batch.** The sim tests in `tests/test_extended_sims.py` (4 of them) all pass. Specifically the test that was failing with `assert "md written" in status, f"Expected 'md written' in status, got {status}"` no longer times out.
+2. **Goal B: The 3 regression tests in `tests/test_reset_session_clears_mma_and_rag.py` still pass.** They check that polluted `tier_usage` data is cleared; pre-populated defaults are not pollution.
+3. **Goal C: `test_app_controller_save_load` passes.** Tier-1 test in `tests/test_context_presets_manager.py` that calls `controller.save_context_preset(preset)` and expects no crash.
+4. **Goal D: `test_load_context_preset_missing_raises_keyerror` passes.** Tier-1 test in `tests/test_project_switch_persona_preset.py` that calls `controller.load_context_preset("NonexistentPreset")` and expects `KeyError` (which requires `self.context_preset_manager.load_all` to be callable).
+5. **Goal E: `test_load_active_project_creates_persona_manager` passes.** Tier-1 test that asserts `not hasattr(ctrl, "persona_manager")` for a fresh controller.
+6. **Goal F: No new failures in tier-1, tier-2, or tier-3 batches.** Match the `33d02bb1` baseline or improve on it.
+
+### Non-Goals
+
+- Refactoring `_switch_project` or `_do_project_switch` to use a state machine.
+- Removing the `try/finally` recursive re-switch in `_do_project_switch` (that's a separate architectural concern; the contract is "if a switch fails, re-queue it", which is a valid design).
+- Modifying the 3 regression tests in `tests/test_reset_session_clears_mma_and_rag.py`.
+- Modifying `tests/test_context_presets_manager.py::test_app_controller_save_load`, `tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager`, or `tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror` (the test code is correct; the production code is wrong).
+- Modifying `simulation/sim_base.py` or `simulation/sim_context.py`.
+- Adding new audit scripts.
+- Updating `docs/`.
+- Filing follow-up tracks.
+- Any "while we're at it" refactors.
+
+## Functional Requirements
+
+### FR1. Pre-populate `mma_tier_usage` on reset
+
+**Where:** `src/app_controller.py:3409`
+
+**What:** Replace the empty-dict reset with the full pre-populated default (matching the shape in `__init__` at line 952-957). The full shape is:
+```python
+{
+  "Tier 1": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-3.1-pro-preview", "tool_preset": None},
+  "Tier 2": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-3-flash-preview", "tool_preset": None},
+  "Tier 3": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-2.5-flash-lite",  "tool_preset": None},
+  "Tier 4": {"input": 0, "output": 0, "provider": "gemini", "model": "gemini-2.5-flash-lite",  "tool_preset": None},
+}
+```
+
+**Why this shape:** It's the same shape `__init__` uses (line 952-957), so the controller's `mma_tier_usage` invariant is preserved across the reset boundary.
+
+**Acceptance:**
+- `tests/test_reset_session_clears_mma_and_rag.py::test_reset_session_clears_mma_tier_usage` still passes (the assertion `tier1.get('model') != 'polluted'` holds because `'gemini-3.1-pro-preview' != 'polluted'`).
+- `tests/test_reset_session_clears_mma_and_rag.py::test_reset_session_clears_mma_status` still passes (untouched by the change).
+- `tests/test_reset_session_clears_mma_and_rag.py::test_reset_session_clears_active_tier` still passes (untouched by the change).
+- `tests/test_extended_sims.py::test_context_sim_live` passes.
+- `tests/test_extended_sims.py::test_ai_settings_sim_live`, `test_tools_sim_live`, `test_execution_sim_live` pass.
+
+### FR2. Make `_flush_to_project` defensive against missing `model`
+
+**Where:** `src/app_controller.py:2639`
+
+**What:** Change `d["model"]` to `d.get("model")` (or `d.get("model", "")`). The rest of the dict comprehension already uses `.get()` for `provider` and `tool_preset`; `model` is the only one that does a hard `[]` lookup.
+
+**Why:** Defense in depth. Other code paths can produce partial `mma_tier_usage[tier]` dicts (e.g. `_handle_mma_state_update` at line 484-497 replaces the entry with whatever the caller sends). Even with FR1, future regressions that produce empty/partial dicts will not crash the project save.
+
+**Acceptance:**
+- `mma_sec["tier_models"]` is written successfully even if some tier's `mma_tier_usage[tier]` is missing the `model` key. The resulting TOML field would be `model = ""` (or the default value), not a crash.
+- No existing tests break.
+
+### FR3. Re-add `self.context_preset_manager = ContextPresetManager()` to `__init__`
+
+**Where:** `src/app_controller.py:__init__` — between line 1183 (end of `_settable_fields` block) and line 1185 (`self.perf_monitor = ...`)
+
+**What:** Insert the line `self.context_preset_manager = ContextPresetManager()` at the same position it occupied in commit `c039fdbb` (immediately before `self.perf_monitor            = performance_monitor.get_monitor()`).
+
+**Why:** `save_context_preset` (line 3019) and `load_context_preset` (line 3023) both dereference `self.context_preset_manager`. The init line was lost in `72f8f466`. Without it, both methods crash with `AttributeError: 'NoneType' object has no attribute 'save_preset'`.
+
+**Acceptance:**
+- `tests/test_context_presets_manager.py::test_app_controller_save_load` passes (it calls `controller.save_context_preset(preset)` and asserts the project is updated).
+- `tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror` passes (it calls `controller.load_context_preset("NonexistentPreset")` and expects `KeyError`; the KeyError can only be raised if `self.context_preset_manager.load_all(self.project)` is callable).
+- No existing tests break.
+
+### FR4. Remove `persona_manager` from `_LAZY_MANAGER_DEFAULTS` in `__getattr__`
+
+**Where:** `src/app_controller.py:1266-1275` (the `_LAZY_MANAGER_DEFAULTS` set)
+
+**What:** Remove the string `"persona_manager"` from the set. The other 5 names stay (verify in batch). Also fix or remove the misleading comment that says "hasattr() still returns False for non-mocked access paths because callers wrap in try/except for AttributeError when they need to distinguish 'lazy' from 'absent'" — this is incorrect.
+
+**Why:** `__getattr__` returning `None` makes `hasattr()` return `True`. The test `test_load_active_project_creates_persona_manager` asserts `not hasattr(ctrl, "persona_manager")` for a fresh controller, which is the correct Python-semantics check. The comment justifying the lazy default is wrong.
+
+**Acceptance:**
+- `tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager` passes (the assertion `not hasattr(ctrl, "persona_manager")` holds for a fresh controller).
+- After `_load_active_project()` is called, `hasattr(ctrl, "persona_manager")` is True and `ctrl.persona_manager` is a `PersonaManager` instance.
+- No existing tests break. (The 5 other names in `_LAZY_MANAGER_DEFAULTS` may have lazy-default callers — verify in the batch run.)
+
+## Non-Functional Requirements
+
+- **NFR1: 1 import, no new functions, ~10 line changes total.** Surgical. Two file edits in `src/app_controller.py`.
+- **NFR2: No regressions.** Tier-1 and tier-2 batch results must match the `33d02bb1` baseline.
+- **NFR3: 2 atomic commits.** One per FR. Not batched.
+- **NFR4: 1-space indent, CRLF, type hints.** Per project conventions.
+- **NFR5: 1 regression test added.** A unit test that proves `KeyError: 'model'` no longer occurs in the post-reset flush path. The test must NOT be a copy of the existing 3 tests in `tests/test_reset_session_clears_mma_and_rag.py`; it must be a NEW test that exercises the specific code path that was crashing.
+
+## Architecture Reference
+
+- **`src/app_controller.py:952-957`** — `mma_tier_usage` default shape in `__init__`. This is the shape FR1 must match.
+- **`src/app_controller.py:1183-1185`** — `__init__` end of `_settable_fields` block and start of `self.perf_monitor = ...`. FR3 inserts the missing `context_preset_manager` init between these.
+- **`src/app_controller.py:1266-1281`** — `_LAZY_MANAGER_DEFAULTS` set and its consumer in `__getattr__`. FR4.
+- **`src/app_controller.py:2639`** — `_flush_to_project` line that crashes. FR2.
+- **`src/app_controller.py:3019-3023`** — `save_context_preset` and `load_context_preset`. FR3 ensures these have a non-None `context_preset_manager` to dereference.
+- **`src/app_controller.py:3358-3409`** — `_handle_reset_session`. FR1.
+- **`src/app_controller.py:2789-2822`** — `_do_project_switch`. NOT changed in this track; the recursive re-switch is a valid design; the bug is the upstream `_flush_to_project` crash, not the re-switch.
+- **`src/app_controller.py:2830-2848`** — `_switch_project`. NOT changed.
+- **`tests/test_reset_session_clears_mma_and_rag.py`** — 3 regression tests from `fe240db4`. Must continue to pass.
+- **`tests/test_extended_sims.py`** — 4 sim tests that have been failing. FR1+FR2 unblock them.
+- **`tests/test_context_presets_manager.py::test_app_controller_save_load`** — tier-1 test that fails due to Bug 2. FR3 unblocks it.
+- **`tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager`** — tier-1 test that fails due to Bug 3. FR4 unblocks it.
+- **`tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror`** — tier-1 test that fails due to Bug 2. FR3 unblocks it.
+
+## Out of Scope
+
+- Refactoring `_switch_project` to use a state machine
+- Removing the recursive re-switch in `_do_project_switch`'s `finally`
+- Modifying the 3 tests in `tests/test_reset_session_clears_mma_and_rag.py`
+- Modifying `tests/test_context_presets_manager.py::test_app_controller_save_load`
+- Modifying `tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager`
+- Modifying `tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror`
+- Refactoring `simulation/sim_base.py` or `simulation/sim_context.py`
+- Removing the other 5 names (`context_preset_manager`, `tool_preset_manager`, `preset_manager`, `vendor_state`, `perf_monitor`) from `_LAZY_MANAGER_DEFAULTS` — only `persona_manager` is removed in FR4. Verify the others in the batch; if any of them break, file a follow-up.
+- Adding new audit scripts
+- Doc updates
+- Follow-up tracks
+- Any "while we're at it" refactors
+
+## Verification Criteria
+
+### Phase 1 (COMPLETE — verified 2026-06-10)
+
+1. ✅ `src/app_controller.py:3409` pre-populates `mma_tier_usage` with the full default shape (model, provider, tool_preset, input, output for all 4 tiers).
+2. ✅ `src/app_controller.py:2639` uses `d.get("model")` (or equivalent) instead of `d["model"]`.
+3. ✅ `src/app_controller.py:__init__` contains `self.context_preset_manager = ContextPresetManager()` between the `_settable_fields` block and `self.perf_monitor = ...`.
+4. ✅ `src/app_controller.py:1266-1275` does NOT contain `"persona_manager"` in `_LAZY_MANAGER_DEFAULTS`. The misleading comment is fixed or removed.
+5. ✅ A new unit test in `tests/test_mma_tier_usage_reset_fix.py` verifies the post-reset flush doesn't crash.
+6. ✅ `tests/test_reset_session_clears_mma_and_rag.py` (3 tests) still pass.
+11. ✅ `tests/test_context_presets_manager.py::test_app_controller_save_load` passes.
+12. ✅ `tests/test_project_switch_persona_preset.py::test_load_active_project_creates_persona_manager` passes.
+13. ✅ `tests/test_project_switch_persona_preset.py::test_load_context_preset_missing_raises_keyerror` passes.
+14. ✅ Tier-1 batch: 5/5 pass.
+15. ✅ Tier-2 batch: 5/5 pass.
+17. ✅ 4 atomic commits (one per FR).
+
+### Phase 2 (PENDING — to be completed)
+
+7. ❌ `tests/test_extended_sims.py::test_context_sim_live` passes in batch.
+8. ✅ `tests/test_extended_sims.py::test_ai_settings_sim_live` passes in batch.
+9. ✅ `tests/test_extended_sims.py::test_tools_sim_live` passes in batch.
+10. ✅ `tests/test_extended_sims.py::test_execution_sim_live` passes in batch.
+16. ❌ Tier-3 batch: 0 new failures vs `33d02bb1` baseline.
+
+### Phase 2 Diagnosis (2026-06-10 full batch run)
+
+The Phase 1 FRs fixed the original `KeyError: 'model'` from `_flush_to_project`. However, the full batch run (not the isolated test run) revealed a SEPARATE failure in the same test:
+
+```
+FAILED tests/test_extended_sims.py::test_context_sim_live
+KeyError: 'paths'
+simulation\sim_context.py:44: KeyError
+```
+
+The traceback shows the SECOND loop in `simulation/sim_context.py:41-47` (a redundant copy of the first loop) failing because `proj['project']['files']['paths']` is missing after the `post_project` round-trip. This loop is duplicated logic (the first loop at lines 32-37 already adds all `.py` files to `paths`; the second loop is supposed to add more, but the round-trip strips `paths`).
+
+**Differences from original failure (which FR1+FR2 fixed):**
+- Original (pre-fix): `KeyError: 'model'` from `_flush_to_project` at `src/app_controller.py:2639`
+- New (post-fix): `KeyError: 'paths'` from `simulation/sim_context.py:44` (in the test code, not production)
+
+**Root cause hypothesis:** The `post_project` hook strips empty/missing fields during the round-trip. In isolation, the first `post_project` succeeds and `paths` is preserved (probably because the first `proj` fetch already had a non-empty `paths` from prior session state). In batch, the live_gui subprocess state is different (different project setup path, prior tests' state has been cleared) and `paths` is empty/absent, so the re-fetch returns a project where `files['paths']` is missing entirely.
+
+**Verification path for Phase 2:**
+- Read the current `sim_context.py:run()` to understand the duplicated loop's intent
+- Either: (a) remove the redundant second loop, (b) make the test handle missing `paths` key with `.setdefault('paths', [])`, (c) fix `_flush_to_project` to preserve empty `paths` lists
+- Re-run the full batch to confirm all 4 sim tests pass
+- Update the verification log
+
+**Per AGENTS.md "Isolated-Pass Verification Fallacy":** the previous run that claimed "4/4 sim tests pass" was based on an isolated run. The full batch is the authoritative test. The track is NOT complete until Phase 2 verification passes.

+# RAG Phase 4 Sync Fix — Implementation Plan (2026-06-10)
+
+> **For Tier 3 workers:** Steps use checkbox (`- [ ]`) syntax. Scope is 1-2 line surgical fix. Do not refactor `_do_rag_sync` more than necessary.
+
+**Goal:** Fix `tests/test_rag_phase4_final_verify.py::test_phase4_final_verify` so `rag_status` reaches `'ready'` after the test configures RAG via the Hook API.
+
+**Tech Stack:** Python 3.11+, pytest.
+
+**HARD CONSTRAINTS:**
+- **NEVER** use `git checkout -- <file>`, `git restore`, `git reset` (AGENTS.md HARD BAN)
+- 1-space indent, CRLF, type hints
+- 1 atomic commit
+- No "while we're at it" refactors
+
+---
+
+## Phase 1: Diagnose and fix
+
+### Task 1.1: Diagnose the failure mode
+
+- [ ] **Step 1.1.1: Read the exact current code**
+  Use `manual-slop_py_get_skeleton` or `manual-slop_get_file_slice` on `src/app_controller.py:1463-1500` and `src/rag_engine.py:88-180`.
+
+- [ ] **Step 1.1.2: Add temporary diagnostic logging**
+  Add 1-line stderr prints in `_do_rag_sync` to see what's happening:
+  - After `if token != self._rag_sync_token: return`: print f"[RAG_DIAG] stale token {token} != current {self._rag_sync_token}, returning"
+  - Before `self._set_rag_status("initializing...")`: print f"[RAG_DIAG] running sync for token {token}"
+  - After setting status to "ready": print f"[RAG_DIAG] set status to 'ready' for token {token}"
+  - In the except branch: print the exception (the existing code already does this)
+
+  Use `manual-slop_edit_file` to add the diagnostic lines.
+
+- [ ] **Step 1.1.3: Run the failing test in isolation**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_rag_phase4_final_verify.py::test_phase4_final_verify -v --timeout=120 -s 2>&1 | Tee-Object -FilePath "tests/artifacts/rag_diag_20260610.log" | Select-Object -Last 80
+  ```
+  Expected: see the diagnostic output in stderr.
+
+- [ ] **Step 1.1.4: Read the diagnostic log and predict the failure mode**
+  Open `tests/artifacts/rag_diag_20260610.log` and look for `[RAG_DIAG]` lines. Determine:
+  - Did the worker for the latest token run?
+  - Did it set status to "ready" or did it error?
+  - Was there a race condition where multiple workers ran but the last one never completed?
+
+### Task 1.2: Apply the fix
+
+- [ ] **Step 1.2.1: Apply the fix in src/app_controller.py or src/rag_engine.py**
+  Based on Step 1.1.4's diagnosis, apply a 1-2 line fix. Most likely candidates:
+  - (a) Force the last worker to actually run by serializing them in the io_pool (not feasible without restructuring)
+  - (b) Use a `threading.Semaphore(1)` to ensure only ONE RAG sync runs at a time
+  - (c) Remove the coalescing complexity — each setter just runs sync directly
+  - (d) Fix the RAGEngine init to handle missing sentence-transformers gracefully (e.g., fall back to a mock provider)
+
+- [ ] **Step 1.2.2: Remove the diagnostic logging**
+  After the fix is verified, remove the `[RAG_DIAG]` lines from `src/app_controller.py`. (Diagnostic code does not ship in production per AGENTS.md.)
+
+- [ ] **Step 1.2.3: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('src/app_controller.py').read()); print('OK')"
+  ```
+
+- [ ] **Step 1.2.4: Verify import**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "from src.app_controller import AppController; print('import OK')"
+  ```
+
+### Task 1.3: Verify in isolation
+
+- [ ] **Step 1.3.1: Run the RAG test in isolation**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_rag_phase4_final_verify.py::test_phase4_final_verify -v --timeout=120
+  ```
+  Expected: 1/1 pass.
+
+### Task 1.4: Verify in batch
+
+- [ ] **Step 1.4.1: Run all 4 sim tests in isolation (regression check)**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_extended_sims.py -v --timeout=300
+  ```
+  Expected: 4/4 pass.
+
+- [ ] **Step 1.4.2: Run the full tier-3-live_gui batch (authoritative)**
+  ```powershell
+  cd C:\projects\manual_slop; uv run .\scripts\run_tests_batched.py 2>&1 | Tee-Object -FilePath "tests/artifacts/post_rag_fix_batch_20260610.log" | Select-Object -Last 50
+  ```
+  Expected: tier-1 5/5, tier-2 5/5, tier-3 either completes fully or only halts on a DIFFERENT (unrelated) pre-existing failure.
+
+### Task 1.5: Checkpoint commit
+
+- [ ] **Step 1.5.1: Commit the fix**
+  ```powershell
+  cd C:\projects\manual_slop; git add src/app_controller.py src/rag_engine.py
+  git commit -m "fix(rag): [describe the actual fix]"
+  $h = git log -1 --format='%H'
+  git notes add -m "..." $h
+  ```
+
+- [ ] **Step 1.5.2: Checkpoint commit with batch log**
+  ```powershell
+  cd C:\projects\manual_slop; git add -f tests/artifacts/post_rag_fix_batch_20260610.log
+  git commit -m "conductor(checkpoint): RAG phase 4 sync fix complete"
+  $h = git log -1 --format='%H'
+  git notes add -m "..." $h
+  ```
+
+---
+
+## Final Verification
+
+- [ ] `test_rag_phase4_final_verify.py::test_phase4_final_verify` passes in isolation
+- [ ] 4 sim tests in `test_extended_sims.py` pass in isolation (regression)
+- [ ] Full tier-3-live_gui batch: at least gets past `test_rag_phase4_final_verify`
+- [ ] 1 atomic commit + 1 checkpoint
+
+## Track Done

+After the fix and verification, the track is DONE.

+# RAG Phase 4 Sync Fix — Specification (2026-06-10)
+
+## Overview
+
+This track fixes a pre-existing RAG test failure that halted the `tier-3-live_gui` batch during the `mma_tier_usage_reset_fix_20260610` verification run on 2026-06-10.
+
+**The original bug (FIXED):** `tests/test_rag_phase4_final_verify.py::test_phase4_final_verify` failed with "RAG sync failed. Status: idle" because `_handle_reset_session` set `self.rag_config = None` and the `rag_*` setters check `if self.rag_config:` before doing anything — so the 4 setters fired by the test were all no-ops.
+
+**Fix:** reset `rag_config` to a fresh `RAGConfig()` default (not None) in `_handle_reset_session`, so the setters can mutate it and trigger the sync.
+
+**Status (post-fix):** RAG sync now reaches `'ready'`; the test fails on a SEPARATE downstream assertion (retrieval order — see "Residual issue" below).
+
+## Reproduction (already verified)
+
+```powershell
+cd C:\projects\manual_slop; uv run pytest tests/test_rag_phase4_final_verify.py::test_phase4_final_verify -v --timeout=120
+```
+
+**Result:** 1 failed in 57.39s — `AssertionError: RAG sync failed. Status: idle`
+
+## Suspected root cause
+
+Looking at `src/app_controller.py:1463-1500`:
+
+```python
+def _sync_rag_engine(self) -> None:
+    with self._rag_sync_lock:
+        self._rag_sync_token += 1
+        self._rag_sync_dirty = True
+        token = self._rag_sync_token
+    self.submit_io(lambda: self._do_rag_sync(token))
+
+def _do_rag_sync(self, token: int) -> None:
+    while True:
+        with self._rag_sync_lock:
+            if token != self._rag_sync_token:
+                return                              # ← BUG: returns silently
+            self._rag_sync_dirty = False
+        self._set_rag_status("initializing...")    # ← only sets after the check
+        ...
+```
+
+The coalescing logic is the prime suspect: if 5 setters are called in quick succession (`rag_collection_name`, `files`, `rag_enabled`, `rag_source`, `rag_emb_provider`), each increments the token and submits a worker. The 5 workers all run concurrently. The first worker checks `if token != self._rag_sync_token` — the token from the first call is now stale (token 1 vs current 5), so it returns without setting status. The second worker (token 2) also returns. The third worker (token 3) also returns. Only the LAST worker (token 5) actually proceeds and sets status.
+
+But the io_pool has limited concurrency (4 workers in startup_speedup_20260606, plus more in `_io_pool` for general use). With 5 setters fired in quick succession from the API, 5 workers are submitted. They all race. The LAST one to acquire `_rag_sync_lock` wins.
+
+This SHOULD work — only the worker with the latest token should set the status. But there's a subtle race: if worker for token 5 acquires the lock first, sees its own token, and proceeds. But what if all 5 workers start before any of them acquires the lock? Then the order of acquisition is non-deterministic.
+
+Looking more carefully: the first worker (token 1) runs, acquires lock, sees token=1 but current=5, returns. Now `self._rag_sync_dirty` is whatever it was BEFORE the first worker (let's say False, because no one has set it True yet — wait, but token 1's setter set `self._rag_sync_dirty = True` BEFORE submitting).
+
+Actually, let me re-read:
+```python
+def _sync_rag_engine(self) -> None:
+    with self._rag_sync_lock:
+        self._rag_sync_token += 1
+        self._rag_sync_dirty = True
+        token = self._rag_sync_token
+    self.submit_io(lambda: self._do_rag_sync(token))
+```
+
+So each setter:
+1. Acquires lock
+2. Increments token
+3. Sets dirty=True
+4. Releases lock
+5. Captures `token` (the new value)
+6. Submits worker with the captured `token`
+
+So worker 1 captures token=1, worker 5 captures token=5. All 5 workers are submitted.
+
+In `_do_rag_sync`:
+```python
+while True:
+    with self._rag_sync_lock:
+        if token != self._rag_sync_token:
+            return                              # stale, return
+        self._rag_sync_dirty = False
+    self._set_rag_status("initializing...")
+    # ... do work ...
+    with self._rag_sync_lock:
+        if not self._rag_sync_dirty:
+            return                              # no more setters, done
+        token = self._rag_sync_token
+        self._rag_sync_dirty = False
+```
+
+So worker 1 acquires lock, sees token (1) != self._rag_sync_token (5), returns immediately. Worker 2 same. Worker 3 same. Worker 4 same. Worker 5 acquires lock, sees token (5) == self._rag_sync_token (5), proceeds. Sets status to "initializing...". Does work. Then checks dirty; if no more setters, returns. Sets status to "ready".
+
+This SHOULD work. So why doesn't it?
+
+Possibility 1: The io_pool doesn't process the 5th worker. Maybe the io_pool is full with other work (the test sets a lot of other things, all going through submit_io).
+
+Possibility 2: The worker for token 5 crashes before setting status. The except branch sets status to "error: ...", not "ready". But the test shows "idle", not "error: ...".
+
+Possibility 3: The status is reset by something else. Looking at `_handle_reset_session`:
+```python
+self.rag_status = 'idle'
+```
+But the test doesn't call reset.
+
+Possibility 4: The test is checking the wrong state. The Hook API's `get_value` might be returning a cached value.
+
+Let me look at how `get_value` works in the API hooks.
+
+## Diagnostic plan
+
+1. Add a print or log line in `_do_rag_sync` to see if it's being called and with what token
+2. Add a print after `_set_rag_status` to see what status is being set
+3. Run the test and observe
+4. Once we know the actual failure mode, fix it
+
+## Goals
+
+1. The RAG phase 4 test passes in isolation
+2. The RAG phase 4 test passes in the full tier-3-live_gui batch (or at least doesn't halt it)
+3. No regression in the 4 sim tests in tests/test_extended_sims.py
+4. No regression in other RAG tests in tests/test_rag_*.py
+
+## Non-Goals
+
+- Refactoring `_do_rag_sync` (just fix the bug)
+- Changing the RAG test design
+- Adding new RAG features
+- Updating documentation
+- Filing follow-up tracks
+
+## Functional Requirements
+
+### FR1. RAG sync reaches 'ready' after configuration
+
+**Where:** `src/app_controller.py` (or `src/rag_engine.py` if the issue is in RAGEngine init)
+
+**What:** After the test sets `rag_enabled=True`, `rag_source='chroma'`, `rag_emb_provider='local'`, the `_do_rag_sync` worker must complete and set `rag_status='ready'` (or 'error: ...' with a clear message if it can't).
+
+**Why:** The RAG test polls for 'ready' and fails if it doesn't see it within 50s.
+
+**Acceptance:**
+- `test_rag_phase4_final_verify.py::test_phase4_final_verify` passes
+- 4 sim tests in `test_extended_sims.py` still pass
+
+## Non-Functional Requirements
+
+- NFR1: 1-2 line fix, surgical
+- NFR2: No new dependencies
+- NFR3: 1 atomic commit
+
+## Architecture Reference
+
+- `src/app_controller.py:1463-1500`: `_sync_rag_engine` + `_do_rag_sync` (the coalescing logic)
+- `src/app_controller.py:1848-1852`: rag_config initialization in project load
+- `src/rag_engine.py:22-53`: lazy imports (`_get_sentence_transformers`, etc.)
+- `src/rag_engine.py:88-108`: RAGEngine `__init__` + `_init_embedding_provider`
+- `tests/test_rag_phase4_final_verify.py`: the failing test
+
+## Out of Scope
+
+- Refactoring `_do_rag_sync` to a state machine
+- Adding observability/metrics to the RAG sync
+- Speeding up RAG startup
+- Adding new RAG embedding providers

+# set_value('ai_input') Audit
+
+## Current Status (as of 2026-06-09)
+**Test `tests/test_gui2_parity.py::test_gui2_set_value_hook_works` PASSES in isolation** (4.50s).
+
+Prior report (`rag_work_final_20260609_pm.md`, 2026-06-09) said it was a batch failure. This audit verifies the current state.
+
+## Endpoint code path
+
+### Routing map (src/app_controller.py:1052)
+```python
+self._settable_fields: Dict[str, str] = {
+    'ai_input':                          'ui_ai_input',
+    ...
+}
+```
+
+### Handler (src/app_controller.py:554-571)
+```python
+def _handle_set_value(controller: 'AppController', task: dict):
+    item = task.get("item")
+    value = task.get("value")
+    if item in controller._settable_fields:
+        attr_name = controller._settable_fields[item]
+        setattr(controller, attr_name, value)
+        ...
+```
+
+### Init state (src/app_controller.py:996)
+```python
+self.ui_ai_input: str = ""
+```
+
+### __getattr__ allowlist (src/app_controller.py:1239)
+`ui_ai_input` IS in `_UI_FLAG_DEFAULTS` (so `hasattr()` returns True).
+
+## Expected flow
+1. `client.set_value('ai_input', 'hello')` → POST /api/gui with `{"action": "set_value", "item": "ai_input", "value": "hello"}`
+2. Endpoint dispatches to `_handle_set_value` (via the action handler map at line 1190)
+3. `_handle_set_value` looks up `_settable_fields["ai_input"]` → `"ui_ai_input"`
+4. `setattr(controller, "ui_ai_input", "hello")` → `controller.ui_ai_input = "hello"`
+5. `client.get_value('ai_input')` → POST /api/gui with `{"action": "get_value", "item": "ai_input"}`
+6. Returns `controller.ui_ai_input` = `"hello"`
+
+## Actual flow (verified 2026-06-09)
+Test PASSES in isolation. Both `set_value` and `get_value` work correctly.
+
+## Prior failure (per rag_work_final_20260609_pm.md)
+The prior report (2026-06-09 PM) said:
+> `test_gui2_set_value_hook_works` batch failure — `set_value` hook returns `'queued'` but `get_value('ai_input')` returns `''` after 1.5s. Different code path from RAG, pre-existing, not investigated this session per the Deduction Loop rule (2-failure cap). Likely a `setattr` routing issue in `gui_2.py` (same class of bug as the earlier `_UI_FLAG_DEFAULTS` fix).
+
+The commit `bcdc26d0` ("fix(gui): correct __getattr__ to not silently return None for missing ui_ attrs") from the prior session likely fixed the underlying `__getattr__` issue. The test now passes in isolation.
+
+## Remaining risk: BATCH behavior
+The test passes in isolation but was reported as a BATCH failure. The batch-vs-isolation gap is the same pattern as the RAG test:
+- In isolation, the live_gui subprocess starts FRESH, controller state is clean.
+- In batch, state from prior tests may have left a different default for `ui_ai_input` (e.g., a prior test set it to a non-empty value, and the session-scoped fixture didn't reset between tests).
+
+## Recommendation
+1. Run the test in the live_gui tier-3 batch to confirm the batch-vs-isolation gap.
+2. If batch still fails, the fix is to add `controller.ui_ai_input = ""` to the `_handle_reset_session` method (which is called by `client.reset_session()` in the conftest fixture's `finally` block).
+3. Alternatively, the test may need to call `client.reset_session()` at the start to ensure a clean state.
+
+## Files affected

+- src/app_controller.py:1052 (`_settable_fields` map — already has `ai_input`)

+    self.submit_io(_task)
+```
+
+## Coalescing mechanism
+NONE. Every setter call immediately submits a fresh task to the io_pool. There is no debounce, no token check, no dirty flag.
+
+## Lock
+`self._rag_engine_lock` exists (line 1482) but only protects the assignment of `self.rag_engine = engine`. The construction of `RAGEngine(...)` runs WITHOUT the lock, so two tasks can be building engines simultaneously.
+
+## Race scenario
+1. Test fires `set_rag_collection_name("name_A")` → submit task T1 to io_pool
+2. Test fires `set_rag_enabled(True)` 50ms later → submit task T2 to io_pool
+3. T1 starts on io_pool thread #1, starts constructing `RAGEngine(self.rag_config, ...)` with collection_name="name_A"
+4. T2 starts on io_pool thread #2, starts constructing `RAGEngine(self.rag_config, ...)` with collection_name="name_B"
+5. T1 finishes first, acquires `_rag_engine_lock`, sets `self.rag_engine = engine_A` (collection_name="name_A")
+6. T2 finishes, acquires lock, sets `self.rag_engine = engine_B` (collection_name="name_B")  ← LAST WRITER WINS
+7. Test queries `self.rag_engine.vector_store.collection_name` → gets "name_B" (the most recent setter)
+8. But the engine was constructed with whatever the controller's rag_config was AT THE TIME of construction. If `_rebuild_rag_index` was called from T1 with files that exist at the time, but T2's engine_A already had different state...
+
+## Why this is non-deterministic
+- T1's engine may have indexed files using its config snapshot
+- T2's engine may have indexed DIFFERENT files using ITS config snapshot
+- Whichever finishes LAST is the one that survives
+- The test may have set `rag_collection_name=A` expecting that to be used; but T2 (which set `rag_enabled=True` later) wins the race, and engine_B has `collection_name=B` not A
+
+## Fix outline (for Phase 4)
+1. Add to `__init__`: `self._rag_sync_token: int = 0`, `self._rag_sync_dirty: bool = False`, `self._rag_sync_lock: threading.Lock`
+2. In `_sync_rag_engine`: increment token, set dirty=True, submit task with current token
+3. In the task: check if token is still current. If not, return early (a newer sync will pick up the changes). If yes, build the engine, check dirty again, if clean return, else loop to pick up new changes.
+
+## Files affected

+- src/app_controller.py:1037 area (AppController.__init__ state)

+# Track Specification: Test Infrastructure Hardening (2026-06-09)
+
+> **Status:** SPEC FOR APPROVAL. The user has asked for a single track to "kill the test regression nightmare" so the 4 upcoming tracks (qwen_llama_grok, data_oriented_error_handling, data_structure_strengthening, mcp_architecture_refactor) can land on a clean test bed.
+>
+> **Inheritance:** This track absorbs and supersedes:
+> - `docs/reports/test_infra_hardening_foundation_20260608.md` (foundation, 5 phases proposed)
+> - `docs/reports/batch_resilience_plan_20260608.md` (4 solutions; Solution A + C recommended)
+> - `docs/reports/rag_test_batch_failure_status_20260609_pm3.md` (filesystem hygiene findings #1-5)
+> - `docs/reports/rag_work_final_20260609_pm.md` (remaining failures: io_pool race, set_value hook)
+> - The implicit "fix test in batch" goal that has been chasing the Tier 2 for 4+ days
+
+---
+
+## Overview
+
+The test suite has accumulated 49+ live_gui tests that share a single session-scoped subprocess. Recent regression hunts have surfaced 3 distinct failure modes that keep re-emerging under different masks:
+
+1. **Subprocess state pollution** — the 4 sims in `test_extended_sims.py` mutate controller state (`current_provider`, `ui_*` attrs, MMA workflows, RAG sync); subsequent tests in the same batch read dirty state.
+2. **Filesystem hygiene** — the `live_gui` fixture creates `tests/artifacts/live_gui_workspace/` as a HARDCODED relative path; 6 test files re-derive the path independently; `RAGEngine.index_file` joins `base_dir + file_path` with `base_dir` possibly being a relative path, so indexing silently no-ops in batch (the root cause of the RAG test batch failure).
+3. **io_pool race in `_sync_rag_engine`** — multiple setters in quick succession submit parallel sync tasks, last-finished-wins, indexing is non-deterministic.
+
+Each of these has been "fixed" in isolation (RAG dim-mismatch recursion, CWD fallback, embedding provider error surface, ini_content str/bytes sentinel, indent on `_capture_workspace_profile`) but the underlying architectural problems remain. The Tier 2 keeps finding new symptoms.
+
+**This track kills the nightmare by fixing the three root causes with surgical, contained, testable changes that the 4 upcoming tracks need as a precondition.**
+
+---
+
+## Current State Audit (as of 2026-06-09)
+
+### Already Implemented (DO NOT re-implement)
+
+- ✅ `live_gui` fixture exists at `tests/conftest.py:282` (session-scoped)
+- ✅ Fixture kills subprocess on teardown (`tests/conftest.py:516-547`)
+- ✅ `/api/gui_health` endpoint surfaces degraded state (commit `1c565da7`)
+- ✅ Pre-flight `get_gui_health()` check in `test_full_live_workflow` (commit `51ecace4`)
+- ✅ `try/except` around `immapp.run` (commit `1c565da7`)
+- ✅ `_UI_FLAG_DEFAULTS` allowlist for `__getattr__` (commit `bcdc26d0`)
+- ✅ `_ini_capture_ready` defer-not-catch flag for `imgui.save_ini_settings_to_memory` (commit `d7487af4`)
+- ✅ `_capture_workspace_profile` indent fix (sub-track 1 of `live_gui_test_hardening_v2`, commit `26e0ced4`)
+- ✅ `ini_content` str/bytes contract test (`tests/test_workspace_profile_serialization.py`)
+- ✅ `LogPruner` busy-loop backoff (commit `ac08ee87`)
+- ✅ RAG dim-mismatch wipe (commit `64bc04a6`)
+- ✅ RAG `_validate_collection_dim` recursion fix (commit `644d88ab`)
+- ✅ RAG `index_file` CWD fallback (commit `eb8357ec`, uncommitted as of report; needs to be committed as defensive fix)
+- ✅ `sentence-transformers` available in dev env via `[local-rag]` extra (commit `a341d7a7`)
+- ✅ `_sync_rag_engine` surfaces embedding_provider init failure (commit `e62266e8`)
+- ✅ `test_required_test_dependencies.py` enforces test-time deps (commit `b801b11c`)
+- ✅ `isolate_workspace`, `reset_paths`, `reset_ai_client`, `vlogger` autouse fixtures
+- ✅ `audit_main_thread_imports.py` and `audit_weak_types.py` static CI gates
+- ✅ `check_test_toml_paths.py` audit script (CI gate for real-TOML references)
+- ✅ Batch tier-1 + tier-2 + tier-3 + tier-H + tier-P structure (`scripts/run_tests_batched.py`)
+
+### Gaps to Fill (This Track's Scope)
+
+#### Gap 1: `live_gui` subprocess scope + per-test dirty-state guard
+- **What exists:** Session-scoped `live_gui` fixture. Subprocess state survives across 49+ tests.
+- **What's missing:** When a test dies (IM_ASSERT, error result, etc.) the subprocess is degraded; subsequent tests in different files get dirty state. The pre-flight `get_gui_health()` check is file-local, not test-local, and only checks health, doesn't recover.
+- **Real symptom:** `test_rag_phase4_final_verify` passes in isolation, fails in batch. `test_gui2_set_value_hook_works` returns `''` instead of queued value. `test_rag_phase4_stress` non-deterministic indexing.
+
+#### Gap 2: Filesystem hygiene for `live_gui_workspace`
+- **What exists:** `tests/conftest.py:412` hardcodes `Path("tests/artifacts/live_gui_workspace")`. 6 test files re-derive the same path independently.
+- **What's missing:** The path is relative to CWD. When the test runner or prior tests shift CWD, all downstream path joins break. `RAGEngine.index_file` joins `base_dir + file_path`; when `base_dir` is relative and CWD has drifted, the file doesn't exist, indexing silently no-ops.
+- **Real symptom:** RAG test in batch finds 0 documents in collection. `chroma_test_final_verify` count=0. `chroma_db` collection count=0. `chroma_test_stress` count=0. Only `chroma_manual_slop` (the user's project, NOT a test) has 328 docs from a separate session.
+- **Files affected:**
+  - `tests/conftest.py:412` (HARDCODED)
+  - `tests/test_rag_phase4_final_verify.py:20`

+
+#### Gap 3: `_sync_rag_engine` io_pool race
+- **What exists:** `src/app_controller.py` `_sync_rag_engine` submits a sync task to `_io_pool` for each `set_value` that mutates `rag_config`. Multiple setters in quick succession → multiple parallel sync tasks → non-deterministic indexing.
+- **What's missing:** A coalescing/debounce pattern that serializes sync attempts within a short window (e.g., 100ms).
+- **Real symptom:** Test fires 5 setters (`rag_collection_name`, `files`, `rag_enabled`, `rag_source`, `rag_emb_provider`) in succession. Each submits a sync. The last one to *finish* wins, but indexing happens against whichever engine finished last. The test then asserts on the wrong engine's output.
+
+#### Gap 4: `set_value` hook test failure (pre-existing, separate code path)
+- **What exists:** `test_gui2_set_value_hook_works` line 41 — `set_value` returns `'queued'` but `get_value('ai_input')` returns `''` after 1.5s.
+- **What's missing:** A `setattr` routing issue in `gui_2.py` similar to the earlier `_UI_FLAG_DEFAULTS` fix. The test's input doesn't actually reach the controller.
+- **Real symptom:** Test fails in batch; same class of bug as the `_UI_FLAG_DEFAULTS` allowlist bug (commit `bcdc26d0`).
+
+#### Gap 5: Tests assert against dirty subprocess state from prior tests
+- **What exists:** Test isolation is implicit (assumes clean state from prior fixture). When a prior test's `set_value` calls pollute the controller, subsequent tests fail in ways unrelated to their code.
+- **What's missing:** A `_reset_controller_state` hook that the `live_gui` fixture exposes, so each test can opt-in to a clean baseline.
+
+---
+
+## Goals
+
+1. **Goal A: Per-test subprocess resilience.** Make the `live_gui` fixture recover from a degraded subprocess BEFORE each test (not just before each file). When the subprocess dies mid-test, the next test gets a fresh one.
+2. **Goal B: Path hygiene for the live_gui workspace.** Refactor `tests/conftest.py:live_gui` to use `tmp_path_factory.mktemp("live_gui_workspace")` and expose the path as a separate fixture. Update all dependent test files to consume the fixture instead of hardcoding the path.
+3. **Goal C: Eliminate `_sync_rag_engine` race.** Add a coalescing/debounce pattern so 5 setters in 100ms produce 1 sync, not 5 parallel syncs.
+4. **Goal D: Fix `set_value` hook routing.** Find the `__setattr__` bug that causes `set_value('ai_input', ...)` to not actually mutate the controller's `ai_input` state, and fix it the same way `_UI_FLAG_DEFAULTS` was fixed.
+5. **Goal E: Test files assert against fresh state.** Add a `_reset_controller_state` fixture that any test can opt into via autouse-on-marker (`@pytest.mark.clean_baseline`).
+6. **Goal F: Verify all 4 upcoming tracks have a clean test bed.** Run the full tier-1 + tier-2 + tier-3 batch and document which tests pass in batch vs. isolation. The 4 upcoming tracks (qwen_llama_grok, data_oriented_error_handling, data_structure_strengthening, mcp_architecture_refactor) start with a known green baseline.
+
+### Non-Goals (Out of Scope)
+
+- ❌ Refactoring the `live_gui` fixture to per-file scope (Solution A in `batch_resilience_plan_20260608.md`). Solution D (autouse health check + respawn) is the surgical alternative; per-file is too coarse.
+- ❌ Refactoring `src/rag_engine.py` to a chunk-based data structure (that's the `chunkification_optimization_20260608_PLACEHOLDER` track).
+- ❌ Migrating `live_gui` tests to mock-based tests (preserves the integration value).
+- ❌ Adding CI infrastructure (this repo has no CI; manual batch runs are the verification).
+- ❌ Fixing the 7 mock_app tests in `test_z_negative_flows.py` (separate code path; deferred).
+- ❌ Fixing the 5 MMA pipeline tests that don't reach "tracks" state (separate code path; deferred).
+- ❌ Fixing the `auto_switch_sim` test (separate code path; deferred).
+- ❌ Doing the `code_path_audit_20260607` work (post-4-tracks; the audit is the post-condition).
+
+---
+
+## Functional Requirements
+
+### FR1. Per-test subprocess health check + respawn
+
+**Where:** `tests/conftest.py:282` (the `live_gui` fixture)
+
+**What:** Add an autouse fixture that runs AFTER `live_gui` and BEFORE each test that uses it. The fixture:
+1. Calls `client.get_gui_health()` with a 1s timeout.
+2. If health is "degraded" OR the response is None OR the call raises, calls `_respawn_subprocess()`.
+3. After respawn (or if health was already OK), verifies the subprocess is alive via the existing `kill_process_tree` machinery.
+
+**API:**
+```python
+@pytest.fixture(autouse=True)
+def _check_live_gui_health(request, live_gui):
+    if "live_gui" in request.fixturenames:
+        handle, _ = live_gui
+        handle.ensure_alive()  # does the health check + respawn
+    yield
+```
+
+**Tests required:**
+- `test_live_gui_respawn_after_kill`: kill the subprocess via the handle, run a no-op test that uses `live_gui`, assert the subprocess is alive at test end.
+- `test_live_gui_health_check_fast_path`: when the subprocess is alive, the health check is <100ms.
+- `test_live_gui_no_respawn_on_clean`: when the subprocess is alive AND `get_gui_health()` returns OK, no respawn happens (verify via a `respawn_count` counter on the handle).
+
+### FR2. Expose `live_gui_workspace` as a separate fixture
+
+**Where:** `tests/conftest.py:282` (the `live_gui` fixture), plus 6 test files
+
+**What:**
+1. Change `live_gui` to create the workspace via `tmp_path_factory.mktemp("live_gui_workspace")` instead of `Path("tests/artifacts/live_gui_workspace")`.
+2. Add a new fixture `live_gui_workspace` that yields the absolute path to the workspace.
+3. The `live_gui` fixture uses `chdir` (or sets the subprocess CWD) to the absolute path; the subprocess inherits the correct CWD.
+4. Update 6 test files to accept `live_gui_workspace` as a fixture parameter and use the absolute path instead of the hardcoded one.
+
+**Tests required:**
+- `test_live_gui_workspace_is_absolute`: assert the workspace path is absolute.
+- `test_live_gui_workspace_unique_per_session`: assert two consecutive sessions get different workspace dirs (per-session `mktemp` returns unique dirs).
+- `test_live_gui_workspace_passed_to_test`: parametrize a test with `live_gui_workspace`, assert the test can create files in it.
+
+**Files to update:**
+- `tests/conftest.py:412` — replace `Path("tests/artifacts/live_gui_workspace")` with `tmp_path_factory.mktemp("live_gui_workspace")`
+- `tests/test_rag_phase4_final_verify.py:20` — accept `live_gui_workspace` fixture
+- `tests/test_rag_phase4_stress.py:21` — accept `live_gui_workspace` fixture
+- `tests/test_saved_presets_sim.py:14, 121` — accept `live_gui_workspace` fixture
+- `tests/test_tool_presets_sim.py:13` — accept `live_gui_workspace` fixture
+- `tests/test_visual_sim_gui_ux.py:79` — accept `live_gui_workspace` fixture
+
+### FR3. Coalesce `_sync_rag_engine` calls
+
+**Where:** `src/app_controller.py:_sync_rag_engine` (or the setter that triggers it)
+
+**What:** Replace the immediate-submit pattern with a debounce/coalesce pattern. Multiple setters within a 100ms window produce ONE sync, run on the next idle moment.
+
+**Approach:** Add a `_rag_sync_token: Optional[int]` and a `_rag_sync_dirty: bool` flag. When a setter mutates `rag_config`, increment the token and set dirty. A background "sync dispatcher" task (or a deferred submit) reads the token, builds the engine once, sets the engine, and clears the flag. If a new setter comes in while a sync is running, increment the token, set dirty, the running sync sees the new token and re-runs once.
+
+**Tests required:**
+- `test_sync_rag_engine_coalesces_five_setters`: fire 5 setters in 50ms, assert only 1 `RAGEngine()` is constructed.
+- `test_sync_rag_engine_rerun_on_token_change`: while a sync is running, fire a setter; assert the sync sees the new token and re-runs once.
+- `test_sync_rag_engine_idempotent_no_changes`: if no setters fire, no sync runs.
+
+### FR4. Fix `set_value` hook routing for `ai_input`
+
+**Where:** `src/gui_2.py:__setattr__` (or `src/app_controller.py:_handle_set_value`)
+
+**What:** Investigate the `__setattr__` / `__setstate__` chain. The test (`tests/test_gui2_set_value_hook_works`) calls `client.set_value('ai_input', 'hello')`, which posts to `/api/gui/set_value`, which calls `controller.<some_method>`. The method either doesn't actually mutate `ai_input` or routes the value to a different attribute (similar to how `_UI_FLAG_DEFAULTS` was incorrectly returning `None`).
+
+**Likely root cause:** Either:
+- The `__setattr__` allowlist only includes certain `ui_` attrs, and `ai_input` is not on it, so the assignment is silently dropped.
+- The `/api/gui/set_value` endpoint has a `field != 'ai_input'` branch that doesn't call the setter.
+
+**Tests required:**
+- `test_set_value_hook_ai_input`: assert that after `set_value('ai_input', 'hello')` and a 0.5s wait, `get_value('ai_input')` returns `'hello'`.
+- `test_set_value_hook_temperature`: same for `temperature`.
+- `test_set_value_hook_persists`: same for `model_name`.
+
+**Diagnostic test (write first):** A test that introspects the controller's `__dict__` and the API hook's parameter-to-handler mapping to find the missing branch.
+
+### FR5. Optional clean-baseline marker
+
+**Where:** `tests/conftest.py` (new fixture), test files that want it
+
+**What:** Add a `@pytest.mark.clean_baseline` marker. An autouse fixture detects the marker and calls a `_reset_controller_state` method on the controller before the test starts. The reset clears: `ai_input`, `ai_status`, `ai_response`, `current_provider`, `current_model`, `rag_config`, `files`, `mma_streams`, `mma_epic_input`, `mma_proposed_tracks`, plus any field set by a prior test.
+
+**API:**
+```python
+@pytest.fixture(autouse=True)
+def _clean_baseline(request, live_gui):
+    if request.node.get_closest_marker("clean_baseline"):
+        handle, _ = live_gui
+        handle.client.reset_session()  # existing endpoint, plus extended reset
+    yield
+```
+
+**Tests required:**
+- `test_clean_baseline_resets_ai_input`: set `ai_input='polluted'`, mark test with `clean_baseline`, assert `ai_input` is `''` at test start.
+- `test_clean_baseline_resets_rag_config`: same for `rag_config`.
+
+### FR6. Verify the 4 upcoming tracks have a clean test bed
+
+**Where:** `scripts/run_tests_batched.py` (no changes); verification in this track's final phase
+
+**What:** Run the full tier-1 + tier-2 + tier-3 batch and document which tests pass. Produce a "test bed health report" as a markdown file in `docs/reports/test_bed_health_20260609.md`. The report lists:
+- Tier-1 unit tests: all pass (already verified in `rag_work_final_20260609_pm.md`)
+- Tier-2 mock_app tests: all pass
+- Tier-3 live_gui tests: pass/fail per file, with the failure mode
+- A "before" / "after" diff so the user can see the impact
+
+---
+
+## Non-Functional Requirements
+
+- **NFR1: Per-test overhead < 200ms.** The autouse `_check_live_gui_health` fixture must add <200ms to each test that uses `live_gui`. The 49 live_gui tests × 200ms = 9.8s additional batch time. Acceptable.
+- **NFR2: No regressions in tier-1 / tier-2.** All unit tests and mock_app tests must continue to pass. The fixture change is additive, not destructive.
+- **NFR3: Backward compat for tests that don't opt in.** Tests that don't use `live_gui` are unaffected. Tests that use `live_gui` but don't opt into `clean_baseline` continue to work (they just don't get a reset).
+- **NFR4: No hardcoded paths to C:/projects/manual_slop or ./tests/artifacts/ in production code.** The track's filesystem-hygiene fix is *enforced* by the existing `scripts/check_test_toml_paths.py` audit (extended to also catch `Path("tests/artifacts/")` and `Path("C:/projects/")` in test files).
+- **NFR5: 1-space indentation.** All Python code in this track uses 1-space indentation per `conductor/product-guidelines.md`.
+- **NFR6: CRLF line endings on Windows.** All Python files in this track use CRLF.
+
+---
+
+## Architecture Reference
+
+This track touches the following subsystems (see linked deep-dive guides):
+
+- **Test infrastructure:** `tests/conftest.py`, `scripts/run_tests_batched.py`. See [docs/guide_testing.md](../docs/guide_testing.md) §"7 conftest fixtures" and §"Puppeteer pattern".
+- **AppController state delegation:** `src/app_controller.py` (166KB). See [docs/guide_app_controller.md](../docs/guide_app_controller.md) §"_predefined_callbacks / _gettable_fields Hook API registries" and [docs/guide_state_lifecycle.md](../docs/guide_state_lifecycle.md) §"State Delegation (__getattr__/__setattr__)".
+- **RAG engine:** `src/rag_engine.py`. See [docs/guide_rag.md](../docs/guide_rag.md) §"RAGEngine lifecycle" and §"Sync to controller".
+- **Hook API:** `src/api_hooks.py` + `src/api_hook_client.py`. See [docs/guide_api_hooks.md](../docs/guide_api_hooks.md) §"/api/gui/set_value" and §"Remote Confirmation Protocol".
+- **io_pool:** `src/app_controller.py:_io_pool`. See [docs/guide_architecture.md](../docs/guide_architecture.md) §"Thread domains".
+
+### Key design constraints inherited
+
+- **Defer-not-catch pattern:** `imgui.*` calls before ImGui is ready crash at the C level (0xc0000005). The `_check_live_gui_health` fixture must NOT touch ImGui directly. It uses the existing Hook API (`/api/gui_health`, `/api/status`) which runs in the hook server thread, not the render thread.
+- **Session-scoped fixture:** `live_gui` is session-scoped by design. Per-file or per-test scoping would break cross-test state (e.g., `test_full_live_workflow` expects a fresh `live_gui`, but `test_rag_phase4_stress` depends on the same subprocess the prior 4 sims used). The autouse respawn is the surgical solution.
+- **tmp_path_factory scope:** `tmp_path_factory.mktemp()` is session-scoped (per the pytest docs). Per-test `tmp_path` is a different fixture. The `live_gui_workspace` fixture must use `tmp_path_factory` to be consistent with the session-scoped `live_gui`.
+
+### Key prior decisions to respect
+
+- The `_UI_FLAG_DEFAULTS` allowlist was a HARD-CODED set. The new `set_value` hook fix should follow the same allowlist pattern (consistency with the existing fix) OR use a class-level attribute that derives from `__init__` annotations (the better fix, but the user has not asked for the better fix; this track stays surgical).
+- The existing `run_tests_batched.py` tier structure (tier-1 unit, tier-2 mock_app, tier-3 live_gui, tier-H headless, tier-P perf) is NOT to be restructured. The track works WITH the existing tier structure.
+- The `audit_main_thread_imports.py` and `audit_weak_types.py` static CI gates are the project's enforcement mechanism. The new `Path("tests/artifacts/")` and `Path("C:/projects/")` patterns are added to `check_test_toml_paths.py` (extended) as a third gate.
+
+---
+
+## Out of Scope
+
+The following are explicitly NOT part of this track. They are mentioned so the user knows they are deferred, not forgotten:
+
+1. **Per-file `live_gui` fixture scope (Solution A from `batch_resilience_plan_20260608.md`):** Not needed if the per-test autouse respawn works. May revisit if the per-test respawn has too much overhead.
+2. **Refactoring `live_gui` fixture to a class-based handle with respawn (Solution B):** Same — only do if per-test respawn is insufficient.
+3. **MMA pipeline tests that don't reach "tracks" state:** 3 tests fail in this pattern (`test_mma_concurrent_tracks_execution`, `test_mma_step_mode_approval_flow`, `test_mma_complete_lifecycle`). These are MMA-engine-state-transition bugs, not test-isolation bugs. Out of scope.
+4. **Negative-flows tests (`test_z_negative_flows.py`):** 3 tests fail in this pattern. They exercise the mock provider's error path. Pre-existing, separate code path. Out of scope.
+5. **`test_auto_switch_sim`:** Workspace auto-switch logic not applying Tier 3 profile. Pre-existing, separate code path. Out of scope.
+6. **`test_prior_session_no_pop_imbalance`:** Already addressed in `live_gui_test_hardening_v2` (commit `26e0ced4`). Verify it still passes.
+7. **`code_path_audit_20260607`:** Post-4-tracks audit. This track unblocks the 4 tracks; the audit runs after.
+8. **`chunkification_optimization_20260608_PLACEHOLDER`:** The comms.log chunkification. Out of scope; the user has not approved it.
+9. **`manual_ux_validation_20260608_PLACEHOLDER`:** The ASCII-sketch workflow. Out of scope; the user has not approved it.
+10. **CI infrastructure:** No CI in this repo. Manual batch runs are the verification.
+
+---
+
+## Verification Criteria
+
+This track is "done" when ALL of the following are true:
+
+1. ✅ All tier-1 unit tests pass in batch (no regression).
+2. ✅ All tier-2 mock_app tests pass in batch (no regression).
+3. ✅ The 6 test files that hardcoded `Path("tests/artifacts/live_gui_workspace")` now use the `live_gui_workspace` fixture.
+4. ✅ `test_rag_phase4_final_verify.py::test_phase4_final_verify` passes in BATCH (after 4 sims) — the primary symptom the user wanted fixed.
+5. ✅ `test_rag_phase4_stress.py` passes in batch OR has a documented reason for the residual flakiness (acceptable per `rag_work_final_20260609_pm.md`'s "out of scope" decision IF the io_pool race fix in FR3 lands).
+6. ✅ `test_gui2_set_value_hook_works` passes in batch.
+7. ✅ The autouse `_check_live_gui_health` fixture is in place; a new test (`test_live_gui_respawn_after_kill`) verifies it.
+8. ✅ The `_sync_rag_engine` coalescing fix is in place; a new test (`test_sync_rag_engine_coalesces_five_setters`) verifies it.
+9. ✅ A `docs/reports/test_bed_health_20260609.md` report is committed, listing pass/fail per test file with the failure mode for any residual failures.
+10. ✅ `scripts/check_test_toml_paths.py` is extended to flag `Path("tests/artifacts/")` and `Path("C:/projects/")` in test files; the audit passes.
+

+
+## Risk Assessment
+
+| Risk | Likelihood | Impact | Mitigation |
+|---|---|---|---|
+| Per-test respawn adds too much overhead (>200ms × 49 tests = 10s) | Medium | Low | Verify with the NFR1 measurement; if exceeded, fall back to per-batch respawn |
+| Per-test respawn breaks cross-test state dependencies | Medium | High | Add a `--no-respawn` pytest flag for tests that need cross-test state; audit the 49 live_gui tests for state dependencies before Phase 1 |
+| `tmp_path_factory.mktemp` changes the workspace path, breaking the on-disk chroma DB persistence assumption | High | Low | Clear `.slop_cache/` dirs at session start; OR add a `live_gui_workspace_persist` opt-in |
+| `_sync_rag_engine` coalescing breaks the existing RAG test that DEPENDS on multiple parallel syncs (unlikely) | Low | Medium | Write the FR3 tests to verify both "5 setters → 1 sync" AND "single setter → single sync" still work |
+| `set_value` hook fix changes behavior for existing tests that assert on the OLD (broken) behavior | Low | High | Run the full tier-3 batch in Phase 3 and verify no regressions |
+| The `tmp_path_factory.mktemp` refactor corrupts `tests/conftest.py` (the previous attempt at this refactor DID corrupt it; commit was reverted per `rag_test_batch_failure_status_20260609_pm3.md`) | High | High | Use `git stash` before each edit; if edit fails, `git stash pop` and try again with `manual-slop_set_file_slice` (which is the recommended surgical tool per `conductor/edit_workflow.md`) |
+
+---
+
+## Phases (summary)
+
+This spec is the entry point. The plan (`plan.md`) breaks these into TDD-ready tasks.
+
+| Phase | Scope | Effort |
+|---|---|---|

+## Approval Required
+
+This spec requires user approval before the plan is written. Per the conductor workflow:
+
+> The spec is the agent's design intent — it explains WHY, not just WHAT.
+> A plan for an unapproved spec is wasted effort.
+
+The user has asked for a track to "kill the test regression nightmare." This spec defines what "kill" means: 5 surgical fixes (FR1-FR5) + a verification report (FR6) that produces a clean test bed for the 4 upcoming tracks. If the user wants more aggressive scope (e.g., refactoring `live_gui` to per-file scope), revise the spec before approving.

+# Workspace Path Finalize — Implementation Plan
+
+> **For Tier 3 workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+>
+> **This is the LAST track on this issue. Do not add scope. Do not refactor anything else. Do not add new tests beyond the 2 in this plan. Do not update docs. Do not file follow-up tracks. Execute exactly what is here, then stop.**
+
+**Goal:** Replace `tmp_path_factory.mktemp("live_gui_workspace")` in `tests/conftest.py` with a per-run timestamped folder under `tests/artifacts/`. Each `uv run pytest` invocation gets its own folder. All live_gui tests in that invocation share it (per-test pollution is intentional and exposes fragility).
+
+**Architecture:** Module-level constants in conftest.py compute the workspace path once at import time. The `live_gui` fixture uses those constants. The `live_gui_workspace` fixture (which already exists) returns the same path via the handle. No env vars, no CLI args, no runner changes.
+
+**Tech Stack:** Python 3.11+, pytest, pathlib.
+
+---
+
+## Pre-Phase 0: Checkpoint
+
+- [ ] **Step 0.1: Pre-edit checkpoint**
+  ```powershell
+  cd C:\projects\manual_slop; git add . && git commit -m "wip: pre-workspace-path-finalize" --allow-empty
+  ```
+
+---
+
+## Phase 1: Apply the 1-line conftest change
+
+Focus: Add module-level constants + change 2 lines in conftest.py.
+
+### Task 1.1: Add the `datetime` import
+
+**Files:**
+- Modify: `tests/conftest.py` (imports section, near the top)
+
+- [ ] **Step 1.1.1: Read the current imports section**
+  Use `manual-slop_get_file_slice` to read `tests/conftest.py:1-30` and see the existing import block.
+
+- [ ] **Step 1.1.2: Add `from datetime import datetime` to the imports**
+  Use `manual-slop_set_file_slice` to insert the import. The exact placement (alphabetical order, or grouped with stdlib imports) depends on what's currently there. Match the existing style.
+
+  **CRITICAL — verify via `ast.parse` after the edit:**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('tests/conftest.py').read()); print('OK')"
+  ```
+
+### Task 1.2: Add module-level constants
+
+**Files:**
+- Modify: `tests/conftest.py` (module-level, after imports, before the first fixture or constant)
+
+- [ ] **Step 1.2.1: Find a good location**
+  Read `tests/conftest.py:1-50` with `manual-slop_get_file_slice`. Find a place after imports and before the first fixture/class definition.
+
+- [ ] **Step 1.2.2: Add the constants**
+  Insert:
+  ```python
+  _RUN_ID = datetime.now().strftime("%Y%m%d_%H%M%S")
+  _RUN_WORKSPACE = Path(f"tests/artifacts/live_gui_workspace_{_RUN_ID}")
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact start_line and end_line of the insertion point.
+
+  **CRITICAL — 1-space indent.** These are top-level statements, no indent. Use exactly the snippet above.
+
+- [ ] **Step 1.2.3: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('tests/conftest.py').read()); print('OK')"
+  ```
+
+### Task 1.3: Change the `live_gui` fixture signature
+
+**Files:**
+- Modify: `tests/conftest.py:453` (the `def live_gui(...)` line)
+
+- [ ] **Step 1.3.1: Read the exact line**
+  Use `manual-slop_get_file_slice` to read `tests/conftest.py:453` and get the exact text.
+
+- [ ] **Step 1.3.2: Remove `tmp_path_factory` from the parameter list**
+  Change:
+  ```python
+  def live_gui(request, tmp_path_factory) -> Generator["_LiveGuiHandle", None, None]:
+  ```
+  to:
+  ```python
+  def live_gui(request) -> Generator["_LiveGuiHandle", None, None]:
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact line.
+
+- [ ] **Step 1.3.3: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('tests/conftest.py').read()); print('OK')"
+  ```
+
+### Task 1.4: Replace the workspace creation
+
+**Files:**
+- Modify: `tests/conftest.py:465` (the `temp_workspace = ...` line)
+
+- [ ] **Step 1.4.1: Read the exact line**
+  Use `manual-slop_get_file_slice` to read `tests/conftest.py:464-466` and get the exact text.
+
+- [ ] **Step 1.4.2: Replace the workspace creation**
+  Change:
+  ```python
+  temp_workspace = tmp_path_factory.mktemp("live_gui_workspace")
+  ```
+  to:
+  ```python
+  temp_workspace = _RUN_WORKSPACE
+  ```
+
+  Use `manual-slop_set_file_slice` with the exact line.
+
+- [ ] **Step 1.4.3: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('tests/conftest.py').read()); print('OK')"
+  ```
+
+### Task 1.5: Run a smoke test
+
+- [ ] **Step 1.5.1: Run a single live_gui test to verify the fixture works**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_gui_startup_smoke.py -v --timeout=30
+  ```
+  Expected: PASS.
+
+- [ ] **Step 1.5.2: Verify the workspace folder was created**
+  ```powershell
+  cd C:\projects\manual_slop; ls tests/artifacts/ | Where-Object { $_.Name -like "live_gui_workspace_*" }
+  ```
+  Expected: a folder like `live_gui_workspace_20260609_HHMMSS` exists.
+
+- [ ] **Step 1.5.3: Verify the subprocess CWD is the new workspace**
+  Run `tests/test_gui_startup_smoke.py` with `-s` to see prints, OR add a temporary `print(handle.workspace)` in the test to verify.
+
+  Expected: handle.workspace is `C:\projects\manual_slop\tests\artifacts\live_gui_workspace_<timestamp>`.
+
+### Phase 1 commit
+
+- [ ] **Step 1.C.1: Commit the conftest change**
+  ```powershell
+  cd C:\projects\manual_slop; git add tests/conftest.py
+  git commit -m "fix(test): per-run workspace under tests/artifacts/ (replaces tmp_path_factory)"
+  $h = git log -1 --format='%H'
+  git notes add -m "Replaces tmp_path_factory.mktemp with _RUN_WORKSPACE, a module-level constant computed once at conftest import time. Each pytest invocation gets tests/artifacts/live_gui_workspace_<YYYYMMDD_HHMMSS>/. All live_gui tests in that invocation share the workspace (per-test pollution is intentional). The workspace is gitignored via tests/artifacts/. 1 import + 2 line changes in conftest.py." $h
+  ```
+
+---
+
+## Phase 2: Add 2 verification tests
+
+Focus: 2 small tests that prove the workspace is at the right path and is gitignored.
+
+### Task 2.1: Write the 2 verification tests
+
+**Files:**
+- Create: `tests/test_workspace_path_finalize.py`
+
+- [ ] **Step 2.1.1: Write the test file**
+  Create `tests/test_workspace_path_finalize.py` with the following content:
+  ```python
+  """Tests for the per-run workspace path (workspace_path_finalize_20260609)."""
+  import subprocess
+  from pathlib import Path
+
+
+  def test_live_gui_workspace_is_under_tests_artifacts(live_gui_workspace: Path) -> None:
+   """The live_gui_workspace fixture returns a path under tests/artifacts/."""
+   s = str(live_gui_workspace).replace("\\", "/")
+   assert s.startswith("tests/artifacts/live_gui_workspace_"), f"Expected tests/artifacts/live_gui_workspace_*, got {s}"
+
+
+  def test_live_gui_workspace_is_gitignored(live_gui_workspace: Path) -> None:
+   """The live_gui_workspace path is gitignored (via tests/artifacts/ in .gitignore)."""
+   result = subprocess.run(
+    ["git", "check-ignore", str(live_gui_workspace)],
+    capture_output=True, text=True, cwd="."
+   )
+   assert result.returncode == 0, f"Workspace {live_gui_workspace} is not gitignored. git check-ignore output: {result.stdout!r} {result.stderr!r}"
+  ```
+
+  **CRITICAL — 1-space indent for all function bodies.** The file-level content has no indent. The `def` lines have no indent. The function body lines have exactly 1 space.
+
+- [ ] **Step 2.1.2: Verify syntax**
+  ```powershell
+  cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('tests/test_workspace_path_finalize.py').read()); print('OK')"
+  ```
+
+- [ ] **Step 2.1.3: Run the 2 tests**
+  ```powershell
+  cd C:\projects\manual_slop; uv run pytest tests/test_workspace_path_finalize.py -v --timeout=30
+  ```
+  Expected: 2/2 pass.
+
+### Phase 2 commit
+
+- [ ] **Step 2.C.1: Commit the verification tests**
+  ```powershell
+  cd C:\projects\manual_slop; git add tests/test_workspace_path_finalize.py
+  git commit -m "test(workspace): verify per-run workspace path and gitignore status"
+  $h = git log -1 --format='%H'
+  git notes add -m "2 tests: test_live_gui_workspace_is_under_tests_artifacts (asserts the path starts with tests/artifacts/live_gui_workspace_) and test_live_gui_workspace_is_gitignored (asserts git check-ignore returns 0 for the workspace path). Both pass with the new _RUN_WORKSPACE constant." $h
+  ```
+
+---
+
+## Phase 3: Run the full batch and verify
+
+Focus: The moment of truth. tier-1 5/5, tier-2 5/5, tier-3 0 new failures. The 4 sim tests in `test_extended_sims.py` now pass.
+
+### Task 3.1: Run the full batch
+
+- [ ] **Step 3.1.1: Run the full batched test suite**
+  ```powershell
+  cd C:\projects\manual_slop; uv run .\scripts\run_tests_batched.py 2>&1 | Tee-Object -FilePath "tests/artifacts/post_finalize_batch_20260609.log" | Select-Object -Last 50
+  ```
+
+  Expected:
+  - tier-1: 5/5 batches pass
+  - tier-2: 5/5 batches pass
+  - tier-3: 0 NEW failures vs the `fe240db4` baseline
+  - The 4 sim tests in `tests/test_extended_sims.py` PASS (they were failing at the `fe240db4` baseline due to the workspace path mismatch)
+
+- [ ] **Step 3.1.2: If tier-3 has new failures, STOP and report**
+  **DO NOT** try to fix new failures in this track. This track's scope is ONLY the workspace path. New failures are out of scope — document them in the git note and move on.
+
+- [ ] **Step 3.1.3: Verify the new workspace folder exists in tests/artifacts/**
+  ```powershell
+  cd C:\projects\manual_slop; ls tests/artifacts/ | Where-Object { $_.Name -like "live_gui_workspace_*" }
+  ```
+  Expected: a fresh folder for this run.
+
+- [ ] **Step 3.1.4: Verify the old %TEMP% workspace is NOT being used**
+  ```powershell
+  cd C:\projects\manual_slop; ls $env:TEMP | Where-Object { $_.Name -like "pytest-of-*" }
+  ```
+  Expected: nothing (or only stale folders from prior runs before this change). The conftest no longer creates new ones in %TEMP%.
+
+### Task 3.2: Commit the batch log
+
+- [ ] **Step 3.2.1: Commit the batch log**

+## Final Verification
+
+- [ ] All 3 commits in place
+- [ ] `tests/conftest.py` no longer uses `tmp_path_factory` in the `live_gui` fixture
+- [ ] `tests/artifacts/live_gui_workspace_<timestamp>/` exists after a pytest run
+- [ ] `.gitignore` already has `tests/artifacts/` (no change needed)
+- [ ] 2 verification tests pass
+- [ ] Full batch: tier-1 5/5, tier-2 5/5, tier-3 [count] failures (should match or improve on `fe240db4` baseline)
+- [ ] The 4 sim tests in `tests/test_extended_sims.py` pass in batch

+## Track Done
+
+After the 3 commits and the full batch verification, the track is DONE. **Do not:**
+- File follow-up tracks
+- Add scope
+- Refactor anything else
+- Update docs
+- Add more tests
+
+**Do:**
+- Report the final state to the user
+- Mark the track as complete in `conductor/tracks.md`
+- Move on to the 4 upcoming tracks (qwen_llama_grok, data_oriented_error_handling, data_structure_strengthening, mcp_architecture_refactor)
+
+---
+
+## Execution Constraints
+
+- **1-space indent, CRLF, type hints.** Per project conventions.
+- **1-line edits via `manual-slop_set_file_slice`.** Per `conductor/edit_workflow.md`. The previous attempt at a conftest refactor was reverted due to corruption — use the recommended surgical tool.
+- **Verify syntax with `ast.parse` after each edit.**
+- **No diagnostic noise in production.** No `print()` statements added to conftest.py for debugging.
+- **Per-task atomic commits.** Not batched.
+- **No "while we're at it" refactors.** This is the LAST track on this issue. Stay in scope.

+# Track Specification: Workspace Path Per-Run (2026-06-09)
+
+## Overview
+
+Conftest creates `tests/artifacts/live_gui_workspace_<timestamp>/` once per pytest invocation. No env vars, no CLI args, no runner changes. The conftest is the source of truth for the workspace path.
+
+**Per-test pollution is intentional** — it exposes fragility, which is the whole point of the test infrastructure hardening track.
+
+**Per-run isolation** — each `uv run pytest` invocation gets a new timestamped folder, so state doesn't leak across runs.
+
+**Why this design:**
+- No env vars (anti-pattern, hidden global state)
+- No CLI args (conftest is the right place for test infrastructure)
+- No runner changes (`run_tests_batched.py` already works)
+- Path is in the project tree under `tests/artifacts/` (gitignored, inspectable, where the sims expect it)
+- `tests/artifacts/` is already gitignored — no repo pollution
+
+## Current State Audit (as of fe240db4)
+
+### Bug
+`tests/conftest.py:453-465`:
+```python
+@pytest.fixture(scope="session")
+def live_gui(request, tmp_path_factory) -> Generator["_LiveGuiHandle", None, None]:
+    ...
+    temp_workspace = tmp_path_factory.mktemp("live_gui_workspace")
+```
+
+This puts the workspace at `C:\Users\<user>\AppData\Local\Temp\pytest-of-<user>\pytest-N\live_gui_workspace0`. That's:
+1. Not in the project tree (user can't find it)
+2. Per-pytest-invocation (re-rolled each run, which is fine), but with an opaque name
+3. Different location from what the sims in `simulation/sim_base.py` expect (`tests/artifacts/...`)
+
+### The fix
+Replace `tmp_path_factory.mktemp("live_gui_workspace")` with a deterministic per-run folder under `tests/artifacts/`:
+```python
+from datetime import datetime
+_run_id = datetime.now().strftime("%Y%m%d_%H%M%S")
+temp_workspace = Path(f"tests/artifacts/live_gui_workspace_{_run_id}")
+```
+
+This:
+- Creates `tests/artifacts/live_gui_workspace_20260609_201530/` on the user's CWD (project root)
+- Each `uv run pytest` invocation gets a new folder (timestamp is per-second granularity)
+- All 49 live_gui tests in that invocation share the workspace
+- The folder is in `tests/artifacts/` (already gitignored, see `git check-ignore tests/artifacts`)
+- The sims' `os.path.abspath("tests/artifacts/temp_*.toml")` resolves to the project tree, which matches
+
+### What to KEEP from Phase 3
+- `tests/test_live_gui_workspace_fixture.py` — the test file that verifies the `live_gui_workspace` fixture
+- The 5 test files updated in `006bb114` to use the fixture instead of hardcoded paths
+- The `_LiveGuiHandle` class with `__iter__`/`__getitem__` backward compat
+- The `_check_live_gui_health` autouse fixture
+- The `clean_baseline` marker
+- The 3-task fix at `fe240db4` (MMA + RAG state reset)
+
+### What to REVERT
+- `tests/conftest.py:465`: change `tmp_path_factory.mktemp("live_gui_workspace")` back to a stable path under `tests/artifacts/`
+
+### What to ADD
+- A `_run_id` module-level constant in conftest.py (computed once at import time)
+- The `live_gui_workspace` fixture already exists; just verify it returns the new path
+
+## Goals
+
+1. **Goal A: Workspace at `tests/artifacts/live_gui_workspace_<timestamp>/`.** Conftest creates the folder, all live_gui tests share it for the duration of the run.
+2. **Goal B: Sim tests pass in full batch.** `tests/test_extended_sims.py` 4 sims pass in tier-3.
+3. **Goal C: Per-run isolation.** Each `uv run pytest` invocation gets a new folder. State from a prior run doesn't pollute.
+4. **Goal D: Inspectable from project tree.** The user can `ls tests/artifacts/live_gui_workspace_*/` to see what the GUI subprocess is working with.
+
+### Non-Goals
+
+- ❌ Per-test isolation. The whole point is per-test pollution = exposed fragility.
+- ❌ Env vars. The user explicitly rejected them.
+- ❌ CLI args. Conftest is the right place.
+- ❌ Runner changes. `run_tests_batched.py` is fine as-is.
+- ❌ Refactoring `simulation/sim_base.py`. It already uses `tests/artifacts/` paths.
+- ❌ New audit scripts.
+- ❌ New tests beyond the 2 verification tests.
+- ❌ Doc updates.
+- ❌ Follow-up tracks.
+
+## Functional Requirements
+
+### FR1. Conftest creates per-run workspace
+
+**Where:** `tests/conftest.py:453-465`
+
+**What:** Change ONE line:
+```python
+# BEFORE (line 453)
+def live_gui(request, tmp_path_factory) -> Generator["_LiveGuiHandle", None, None]:
+    ...
+    temp_workspace = tmp_path_factory.mktemp("live_gui_workspace")
+
+# AFTER
+_RUN_ID = datetime.now().strftime("%Y%m%d_%H%M%S")
+_RUN_WORKSPACE = Path(f"tests/artifacts/live_gui_workspace_{_RUN_ID}")
+
+def live_gui(request) -> Generator["_LiveGuiHandle", None, None]:
+    ...
+    temp_workspace = _RUN_WORKSPACE
+```
+
+Add `from datetime import datetime` to the imports at the top of conftest.py.
+
+### FR2. `live_gui_workspace` fixture returns the new path
+
+**Where:** `tests/conftest.py:673-677` (the existing `live_gui_workspace` fixture)
+
+**What:** The fixture already exists and returns `handle.workspace`. The `handle.workspace` is set in `_LiveGuiHandle.__init__` from `temp_workspace`. So once FR1 is applied, the fixture returns the new path automatically.
+
+Verify with a new test:
+```python
+def test_live_gui_workspace_is_under_tests_artifacts(live_gui_workspace):
+    assert str(live_gui_workspace).replace("\\", "/").startswith("tests/artifacts/live_gui_workspace_")
+```
+
+### FR3. Workspace is gitignored
+
+**Where:** `.gitignore` (already has `tests/artifacts/`)
+
+Verify with a new test:
+```python
+def test_live_gui_workspace_is_gitignored(live_gui_workspace):
+    import subprocess
+    result = subprocess.run(
+        ["git", "check-ignore", str(live_gui_workspace)],
+        capture_output=True, text=True, cwd="."
+    )
+    assert result.returncode == 0, f"Workspace {live_gui_workspace} is not gitignored"
+```
+
+## Non-Functional Requirements
+
+- **NFR1: 1 import + 1 line change.** Add `from datetime import datetime`. Change line 465.
+- **NFR2: No regressions.** Tier-1 and tier-2 batch results must match the `fe240db4` baseline.
+- **NFR3: 1 commit.** Atomic. Not batched.
+- **NFR4: 1-space indent, CRLF, type hints.** Per project conventions.
+
+## Architecture Reference
+
+- **`tests/conftest.py:453-540`** — the `live_gui` session-scoped fixture. Only lines 465 + 453 + the import change.
+- **`tests/conftest.py:673-677`** — the `live_gui_workspace` fixture. No change needed; it returns `handle.workspace` which is the new path.
+- **`scripts/run_tests_batched.py`** — no change.
+- **`simulation/sim_base.py:80-91`** — no change. `os.path.abspath("tests/artifacts/temp_*.toml")` resolves to the project tree, which works.
+- **`.gitignore`** — already has `tests/artifacts/`. No change.
+
+## Out of Scope
+
+- Per-test isolation
+- Env vars
+- CLI args
+- Runner changes
+- Sim refactoring
+- New audit scripts
+- Doc updates
+- Follow-up tracks
+- Any "while we're at it" refactors
+
+## Verification Criteria
+
+1. ✅ `tests/conftest.py:453` no longer takes `tmp_path_factory` parameter
+2. ✅ `tests/conftest.py:465` (or equivalent) reads `_RUN_WORKSPACE` (the timestamped path)
+3. ✅ `tests/artifacts/live_gui_workspace_<timestamp>/` exists after a pytest run
+4. ✅ 2 new verification tests pass
+5. ✅ Full batch: tier-1 5/5, tier-2 5/5, tier-3 0 new failures (or matches `fe240db4` baseline + the 4 sim tests now pass)
+6. ✅ The 4 sim tests in `tests/test_extended_sims.py` pass in batch
+7. ✅ 1 atomic commit
+
+## Execution Plan
+
+This is a 1-commit, 4-step change. No phases. No agent handoffs.
+
+### Step 1: Pre-edit checkpoint
+```powershell
+cd C:\projects\manual_slop; git add . && git commit -m "wip: pre-workspace-path-finalize" --allow-empty
+```
+
+### Step 2: Apply the changes
+Use `manual-slop_set_file_slice` (the recommended surgical tool per `conductor/edit_workflow.md`):
+
+1. Add `from datetime import datetime` to the imports section of `tests/conftest.py`
+2. Add the module-level constants near the top of conftest.py (after imports):
+   ```python
+   _RUN_ID = datetime.now().strftime("%Y%m%d_%H%M%S")
+   _RUN_WORKSPACE = Path(f"tests/artifacts/live_gui_workspace_{_RUN_ID}")
+   ```
+3. Change `tests/conftest.py:453` from `def live_gui(request, tmp_path_factory)` to `def live_gui(request)`
+4. Change `tests/conftest.py:465` from `temp_workspace = tmp_path_factory.mktemp("live_gui_workspace")` to `temp_workspace = _RUN_WORKSPACE`
+
+Verify syntax after each edit:
+```powershell
+cd C:\projects\manual_slop; uv run python -c "import ast; ast.parse(open('tests/conftest.py').read()); print('OK')"
+```
+
+### Step 3: Add 2 verification tests
+Create `tests/test_workspace_path_finalize.py` with the 2 tests in FR2 and FR3.
+
+### Step 4: Run the 2 new tests
+```powershell
+cd C:\projects\manual_slop; uv run pytest tests/test_workspace_path_finalize.py -v --timeout=30
+```
+Expect: 2/2 pass.
+
+### Step 5: Run the full batch
+```powershell
+cd C:\projects\manual_slop; uv run .\scripts\run_tests_batched.py 2>&1 | Tee-Object -FilePath "tests/artifacts/post_finalize_batch_20260609.log" | Select-Object -Last 30
+```
+Expect: tier-1 5/5, tier-2 5/5, tier-3 0 new failures (or 4 sim tests now pass + 1 RAG test now passes).
+
+### Step 6: Commit
+```powershell
+cd C:\projects\manual_slop; git add tests/conftest.py tests/test_workspace_path_finalize.py tests/artifacts/post_finalize_batch_20260609.log
+git commit -m "fix(test): per-run workspace under tests/artifacts/ (no env vars, no tmp_path)"
+$h = git log -1 --format='%H'
+git notes add -m "Replaces tmp_path_factory.mktemp with a per-run timestamped folder under tests/artifacts/. Each pytest invocation gets a new folder; all live_gui tests in that invocation share it (per-test pollution is intentional and exposes fragility, per the test_infrastructure_hardening_20260609 spec). Workspace is gitignored via tests/artifacts/. Sims in simulation/sim_base.py use os.path.abspath('tests/artifacts/...') which resolves correctly from the project root." $h
+```
+
+## Risk Assessment
+
+| Risk | Likelihood | Impact | Mitigation |
+|---|---|---|---|
+| 4-line edit corrupts conftest | Low | High | Use `manual-slop_set_file_slice`; verify syntax with `ast.parse` after each edit; pre-edit checkpoint |
+| `_RUN_ID` collides if two pytest invocations start in the same second | Very low | Low | Acceptable — second-precision is enough for human-driven runs; for CI, add a uuid suffix if needed (out of scope) |
+| Stale workspaces accumulate in `tests/artifacts/` | Medium | Low | They're gitignored; the user can `rm -rf tests/artifacts/live_gui_workspace_*` when needed; out of scope for this track |
+
+## See Also
+
+- **User feedback:** Per-test pollution is intentional. Per-run isolation is the goal. No env vars. No CLI args. Conftest is the source of truth.
+- **Pre-Phase 3 baseline:** `tests/conftest.py` had the workspace at `Path("tests/artifacts/live_gui_workspace")` (no timestamp). Sims worked.
+- **The phantom bug:** CWD drift was already fixed by `os.path.abspath` in `RAGEngine.index_file` (commit `eb8357ec`).
+- **The 3-task fix that mattered:** `fe240db4` (MMA + RAG state reset).
+- **What NOT to do:** `tmp_path_factory` (per-pytest-invocation, opaque, in %TEMP%). Env vars (hidden global state). CLI args (wrong abstraction layer).

+# Chroma Cache Path Styleguide
+
+## The Rule
+
+The ChromaDB persistent vector cache lives at:
+
+```
+<project_root>/tests/artifacts/.slop_cache/chroma_<collection_name>/
+```
+
+**NOT** at the per-run `tests/artifacts/live_gui_workspace_<timestamp>/` subdir.
+
+Tests that interact with RAG **MUST** pre-clean the cache to avoid persistent state from prior tests in the batched run.
+
+## Why This Rule Exists
+
+The chroma cache path is auto-derived from `RAGEngine._init_vector_store()` (`src/rag_engine.py:108-125`):
+
+```python
+db_path = os.path.abspath(os.path.join(
+    self.base_dir, ".slop_cache", f"chroma_{vs_config.collection_name}"
+))
+```
+
+`self.base_dir` is computed as `Path(active_project_path).parent`. **The trailing-slash bug**: when the test config produces a project path ending in `/` (e.g., from `os.path.join` with a trailing `/`), `Path(p).parent` returns the directory ONE LEVEL HIGHER than expected. So the chroma cache lands at `tests/artifacts/.slop_cache/` (the parent of the per-run `live_gui_workspace_<timestamp>/` subdir) instead of inside the per-run subdir.
+
+This was the dominant cause of `tier-3-live_gui` failures in the 2026-06-08 to 2026-06-10 window. A prior batched run with a different embedding provider (e.g., Gemini 3072-dim vs local 384-dim) leaves a corrupt collection on disk. The next test's `search()` raises `chromadb.errors.InvalidDimensionError: Collection expecting embedding with dimension of X, got Y`, the AI request never reaches `'done'` status, and the live_gui test polls timeout at 50×0.5s = 25s.
+
+## The Pre-Cleanup Pattern
+
+RAG tests should wipe the chroma cache BEFORE pushing RAG config. The pattern is in `tests/test_rag_phase4_final_verify.py`:
+
+```python
+from pathlib import Path
+import shutil
+
+def test_phase4_final_verify(live_gui):
+    # Wipe any stale chroma from prior batched runs
+    cache = Path("tests/artifacts/.slop_cache/chroma_test_final_verify")
+    if cache.exists():
+        shutil.rmtree(cache, ignore_errors=True)
+    # ... rest of test
+```
+
+`ignore_errors=True` is required because:
+- On Windows, the chroma client may still hold file handles; `rmtree` may fail with `WinError 32` (sharing violation).
+- If a parallel xdist worker is mid-write, the rmtree can race; `ignore_errors` lets the next worker's write retry.
+
+The `_validate_collection_dim()` mechanism in `RAGEngine` (`src/rag_engine.py:127-213`) also auto-recovers by wiping the dim-mismatched collection (see [docs/guide_rag.md](../docs/guide_rag.md#dimension-mismatch-protection)). But pre-cleaning is faster and avoids the stderr warning.
+
+## Anti-Patterns
+
+❌ **Assuming the cache is per-run:**
+```python
+def test_rag(live_gui, live_gui_workspace):
+    # WRONG: live_gui_workspace is a per-run subdir, but the chroma
+    # cache is at tests/artifacts/.slop_cache/, NOT under live_gui_workspace
+    cache = live_gui_workspace / ".slop_cache" / "chroma_test"
+    if cache.exists():
+        shutil.rmtree(cache)  # Doesn't find the actual cache
+```
+
+❌ **Not pre-cleaning at all:**
+```python
+def test_rag(live_gui):
+    # WRONG: no pre-cleanup. If a prior batched run with a different
+    # embedding provider is on disk, this test will hit dim-mismatch
+    client = ApiHookClient()
+    client.push_event("set_value", {"field": "rag_enabled", "value": True})
+    # ... eventually hangs polling for 'done' status
+```
+
+❌ **Asserting on the FIRST retrieved chunk:**
+```python
+assert "Manual Slop RAG is great" in entry.get("content")
+# WRONG: in batched context, the chroma ordering may rank a .py
+# file first instead of the .txt file. Either file's content
+# proves RAG worked; the assertion must accept either.
+```
+
+## When in Doubt
+
+If a RAG test is flaky in batched runs but passes in isolation, the chroma cache is the #1 suspect. The test's actual chroma path is `Path("tests/artifacts/.slop_cache") / f"chroma_{collection_name}"`. Wipe it before the test starts.

+# Config I/O State Ownership
+
+**Rule:** The `AppController` is the single source of truth for the
+in-memory config (`self.config`) and the only authorized caller of
+the file I/O primitives in `src/models.py`.
+
+## Why
+
+1. **The controller owns the in-memory state.** If other modules
+   write to `config.toml` directly, the controller's `self.config`
+   silently drifts from disk. Tests can corrupt the user's TOML
+   files; users lose data without warning.
+2. **Test isolation breaks.** When `models.save_config(...)` is
+   called from anywhere in `src/`, tests cannot intercept the
+   write without patching the I/O primitive. The test then
+   couples to the file format, not the controller's behavior.
+3. **Path resolution can't be enforced.** The controller respects
+   `SLOP_CONFIG` env var at call time. Direct calls to
+   `models.save_config` would only respect it if the path is
+   re-resolved (which it is in `_save_config_to_disk`, but only
+   because someone remembered).
+
+## What is Forbidden in `src/`
+
+- `models.load_config(...)` (legacy public function)
+- `models.save_config(...)` (legacy public function)
+- `models._load_config_from_disk(...)` (private I/O primitive)
+- `models._save_config_to_disk(...)` (private I/O primitive)
+
+The only allowed call sites are inside `AppController` itself
+(`load_config()` and `save_config()` methods).
+
+## The Public API
+
+```python
+# In AppController:
+def load_config(self) -> Dict[str, Any]:
+    """Re-read the global config.toml from disk and update self.config."""
+    self.config = models._load_config_from_disk()
+    return self.config
+
+def save_config(self) -> None:
+    """Flush self.config to disk."""
+    models._save_config_to_disk(self.config)
+```
+
+Callers (including `gui_2.py`, `commands.py`, etc.) go through
+the controller:
+
+```python
+# In App class methods (gui_2.py): __getattr__ delegates to controller
+self.save_config()      # -> controller.save_config()
+app.save_config()       # -> controller.save_config() (via __getattr__)
+app.load_config()       # -> controller.load_config() (via __getattr__)
+
+# In AppController:
+self.save_config()      # direct
+self.load_config()      # direct
+```
+
+## Test Patterns
+
+Tests should mock the **controller methods**, not the I/O primitives:
+
+```python
+# CORRECT: route through the controller
+with patch('src.app_controller.AppController.load_config',
+           return_value={'ai': {...}, 'projects': {...}}):
+    app = App()  # controller's load_config returns the mock
+
+with patch('src.app_controller.AppController.save_config'):
+    app._save_paths()  # controller's save_config is a no-op
+    app.save_config.assert_called_once()  # verify the call
+
+# WRONG: patch the I/O primitive
+with patch('src.models._save_config_to_disk'):  # bypasses the controller
+    app._save_paths()  # still hits the I/O primitive if production bypasses
+```
+
+The `mock_app` and `app_instance` fixtures in `tests/conftest.py`
+follow the correct pattern: they patch
+`AppController.load_config` and `AppController.save_config` to
+prevent real I/O and to provide a default config.
+

+# Test Workspace Paths — Hard Rule
+
+## TL;DR
+
+Test workspaces live in the project tree under `tests/artifacts/`. Conftest creates them. No env vars. No CLI args. No `tmp_path_factory`. No `%TEMP%`. No runner changes. **The user must be able to find every test workspace by looking in `tests/artifacts/`.**
+
+## The Rule
+
+When creating a test workspace, fixture, or scratch directory for any test infrastructure:
+
+```python
+# CORRECT — conftest creates the path
+from datetime import datetime
+_RUN_ID = datetime.now().strftime("%Y%m%d_%H%M%S")
+_RUN_WORKSPACE = Path(f"tests/artifacts/live_gui_workspace_{_RUN_ID}")
+
+@pytest.fixture(scope="session")
+def live_gui(request):
+    temp_workspace = _RUN_WORKSPACE
+    ...
+```
+
+```python
+# WRONG — env vars
+import os
+WORKSPACE = os.environ.get("LIVE_GUI_WORKSPACE", "tests/artifacts/live_gui_workspace")
+
+# WRONG — CLI args
+def pytest_addoption(parser):
+    parser.addoption("--workspace", action="store", default="tests/artifacts/live_gui_workspace")
+
+# WRONG — tmp_path_factory (lives in %TEMP%, not in project tree)
+def live_gui(request, tmp_path_factory):
+    temp_workspace = tmp_path_factory.mktemp("live_gui_workspace")
+    # Creates: C:\Users\<user>\AppData\Local\Temp\pytest-of-<user>\pytest-N\live_gui_workspace0
+    # User CANNOT FIND THIS from the project tree.
+```
+
+## Why This Rule Exists
+
+This rule was added 2026-06-09 after a 4-day agent churn on workspace paths. The chain of decisions:
+
+1. Original conftest: `temp_workspace = Path("tests/artifacts/live_gui_workspace")`. Sims worked. User could find the workspace. **This was correct.**
+
+2. Phase 3 of test_infrastructure_hardening_20260609: agent changed it to `tmp_path_factory.mktemp("live_gui_workspace")`. The user did not catch this for 2 days. It moved the workspace to `%TEMP%/pytest-of-<user>/...` which:
+   - The user cannot find from the project tree
+   - The sims (which compute `os.path.abspath("tests/artifacts/...")` from the project root) could not find the workspace either
+   - Caused `test_extended_sims.py::test_context_sim_live` to fail with "stale ui - ops disabled" because the sim's project path didn't match the controller's active_project_path
+   - The agent then spent 2 more days trying to fix the sim timing, the MMA state, the RAG state, the watchdog — none of which were the actual cause
+
+3. The user caught the regression. Their feedback: "we should be using a folder in `./tests/`" — i.e., the project tree, not the system temp dir.
+
+4. The agent tried `Path("tests/artifacts/live_gui_workspace")` (no timestamp). That solved the sim issue but was per-session, not per-run. Per-test pollution is desirable (it exposes fragility), so per-run isolation is what we want.
+
+5. The user pushed back on adding CLI args: "have conftest make it, conftest is the right place." The agent then tried env vars as an indirection layer.
+
+6. The user rejected env vars: "env vars are hidden global state, pass it to conftest directly." Conftest is the source of truth.
+
+7. Final solution: conftest creates a per-run timestamped folder under `tests/artifacts/`. One source of truth. No indirection. The user must be able to find every test workspace by looking in `tests/artifacts/`.
+
+## Forbidden Patterns (Hard Bans)
+
+### 1. `tmp_path_factory` for test infrastructure workspaces
+
+`tmp_path_factory` is for pytest's own test isolation (e.g., when a unit test needs a temp dir to write a file). It is **NOT** for test infrastructure workspaces (e.g., the `live_gui` subprocess's CWD). Why:
+
+- `tmp_path_factory` lives in `%TEMP%/pytest-of-<user>/...` — outside the project tree
+- The user cannot find the workspace by looking in the project tree
+- Any code that uses `os.path.abspath("tests/artifacts/...")` from the project root cannot find the workspace
+- The 4 sim tests in `simulation/sim_base.py` are exactly such code
+
+**Use `tmp_path` or `tmp_path_factory` ONLY for:**
+- Unit tests that need a temp file/dir
+- Test data fixtures that don't outlive the test
+- Any case where the path is consumed only by the test itself, not by a subprocess
+
+**Do NOT use for:**
+- The `live_gui` subprocess CWD
+- Any workspace that a long-running subprocess (GUI, server) operates on
+- Any path that other code computes via `os.path.abspath("tests/...")` from the project root
+
+### 2. Environment variables for test paths
+
+Env vars are hidden global state. The user has explicitly banned them. They are also a host for the "I'll just check the env var" anti-pattern, which is what bad coders do.
+
+**Do NOT use `os.environ` for:**
+- Test workspace paths
+- Test configuration that could be a conftest constant
+- Anything that the conftest can compute itself
+
+### 3. CLI args for test paths
+
+The conftest is the right place. CLI args add a layer of indirection between the runner and the test, and they require the runner to be modified to pass them. The user has explicitly rejected this.
+
+**Do NOT add `--workspace=PATH` or similar CLI args.** If you need a path, compute it in conftest.
+
+## The Correct Pattern
+
+```python
+# tests/conftest.py
+
+from datetime import datetime
+from pathlib import Path
+
+# Module-level constants, computed once at conftest import time.
+# Per-pytest-invocation isolation: each `uv run pytest` gets a new folder.
+# Per-test pollution is INTENTIONAL (exposes fragility).
+_RUN_ID = datetime.now().strftime("%Y%m%d_%H%M%S")
+_RUN_WORKSPACE = Path(f"tests/artifacts/live_gui_workspace_{_RUN_ID}")
+
+@pytest.fixture(scope="session")
+def live_gui(request) -> Generator["_LiveGuiHandle", None, None]:
+    temp_workspace = _RUN_WORKSPACE
+    # ... use temp_workspace
+```
+
+## What Lives in `tests/artifacts/`
+
+Everything test-related that needs to be on disk:
+
+- `tests/artifacts/live_gui_workspace_<timestamp>/` — per-run live_gui workspace (this rule)
+- `tests/artifacts/manualslop_layout_default.ini` — read-only default layout
+- `tests/artifacts/*.log` — test logs
+- `tests/artifacts/post_*_batch_*.log` — batch run logs
+
+All of these are gitignored via the existing `tests/artifacts/` entry in `.gitignore`.
+
+## Verification
+
+```bash
+# The workspace must be in the project tree:
+$ ls tests/artifacts/ | grep live_gui_workspace
+live_gui_workspace_20260609_201530
+
+# It must be gitignored:
+$ git check-ignore tests/artifacts/live_gui_workspace_20260609_201530
+tests/artifacts/live_gui_workspace_20260609_201530
+```
+
+## Audit
+
+`scripts/check_test_toml_paths.py` already flags `Path("C:/projects/")` and other hardcoded paths. Add a check for `tmp_path_factory.mktemp` and `os.environ.get.*WORKSPACE` in production-style conftest changes. (This is a follow-up task, not a hard requirement.)

 # Manual Slop Edit Tool Workflow
 
 ## The Problem
+
 The `manual-slop_edit_file` tool requires **exact string matches** (character-for-character). Whitespace differences cause failures. The Python file uses **1-space indentation**.
 
 ## The Rules
 
 ### 1. ALWAYS Use Small, Incremental Edits
+
 **WRONG:** Replace large blocks (50+ lines)
 **RIGHT:** Replace 3-10 lines at a time, verify, repeat
 
 ### 2. Verify Before Editing

-`set_file_slice` does literal line replacement by design. It does not reindent, does not normalize EOL, does not parse decorators. Use it for surgical line-level edits (3-10 lines). If you need to insert or replace a multi-method block, use `manual-slop_edit_file` with verified exact-text old_string/new_string, or use `py_add_def` / `py_update_definition` for class/method-level work.
+The previous rule ("Do not use set_file_slice for multi-line content") was wrong. `set_file_slice` does literal line replacement by design and is the right tool for 3-10 line surgical edits.
+
+**When to use which tool:**
+
+- **`set_file_slice`** for surgical 3-10 line edits where you know the exact line range. Verify the line range with `get_file_slice` first. The `start_line` and `end_line` are 1-indexed and inclusive. The new content must reproduce the line count exactly (or be a precise replacement of the same N lines).
+- **`manual-slop_edit_file`** for exact-string replacement when you don't know the line range, or when the edit has a unique anchor string.
+- **`py_update_definition`** for whole-function replacement (AST-detected).
+- **`py_add_def`** for adding a new method/class to a class.
+- **`py_remove_def`** for removing a method/class.
+
+**The contract-change check (mandatory for any edit that changes a public interface):**
+
+Before any edit, search the codebase for callers of the function/symbol/yield shape you're changing. If your edit changes:
+- A function signature (add/remove/rename a parameter)
+- A return type or yield shape (e.g. `yield process, gui_script` → `yield process, gui_script, workspace_path`)
+- A class hierarchy (add/remove a base class, change a method's name)
+- A module-level function name (rename)
+- A public attribute name
+
+...you MUST update ALL callers in the same atomic commit. Use `py_find_usages` to locate them. If you change a contract and don't update callers, you have broken the codebase.
+
+**The whitespace-and-EOL rule (mandatory for set_file_slice):**
+
+The `new_content` must preserve:
+- The file's line ending convention (CRLF on Windows, LF on Linux — pick from the surrounding file, not from your text editor's default)
+- The indentation of the surrounding code (1 space per level, per `conductor/code_styleguides/python.md` §1)
+- The number of lines replaced (`start_line`..`end_line` must equal `len(new_content.splitlines())`)
+
+If you mismatch any of these, the file will fail to parse. Run `py_check_syntax` and a real `import` after every `set_file_slice`.
+
+### 9. No Diagnostic Noise in Production Code (Added 2026-06-09)
+
+`sys.stderr.write(f"[XYZ_DIAG] ...")` lines added to `src/*.py` for debugging are technical debt the moment they ship. If you need to instrument for a one-time investigation:
+
+- Write the diag output to a log file: `tests/artifacts/<test_name>.diag.log`
+- Or to a standalone diagnostic script under `/tmp/diag_<name>.py` that imports the production module and exercises it
+- Or read the production source with `get_file_slice` and reason about it directly
+
+Do NOT add diag lines to `src/*.py` "temporarily." If you must add them for a single test run, they are part of the same atomic commit as the fix — they do not live uncommitted in the working tree. If you "revert everything," that means the diag lines are also reverted.

 - [Recently Shipped: Live-GUI Test Hardening v2](./tracks/live_gui_test_hardening_v2_20260605/) — All 4 originally-failing live_gui tests now pass. Root cause was bad indentation in `src/gui_2.py:607` (`_capture_workspace_profile` was being parsed as nested inside `_apply_snapshot`); user fixed the indent. The `test_prior_session_no_pop_imbalance` test was refactored to call narrow `render_prior_session_view` (50+ mocks -> 20, runtime 5.79s -> 0.08s).
 - [Recently Shipped: Live-GUI Fragility Fixes v1](./tracks/regression_fixes_20260605/) — str/bytes sentinel fix (`ini=b""` -> `ini=""`) in `_capture_workspace_profile`; +1 new regression unit test (`tests/test_workspace_profile_serialization.py`). Did not unblock the live_gui tests due to deeper sync bug.
 - [Recently Shipped: Multi-Theme TOML System](./tracks/multi_themes_20260604/) — 8 new theme files, public API (`load_themes_from_disk`, `get_syntax_palette_for_theme`, `apply_syntax_palette`), color-callable convention. See [../docs/guide_themes.md](../docs/guide_themes.md) for the authoring guide.
 - [Recently Shipped: Test Regression Fixes (post multi-themes ship)](./tracks/regression_fixes_20260605/) — 11 of 21 failing tests fixed, root cause of remaining live_gui C-level crash identified (`_ini_capture_ready` defer-not-catch pattern).

+## Testing Requirements
+
+These are the process standards the project's test infrastructure enforces. For the full implementation contract (fixture names, anti-patterns, audit scripts), see [docs/guide_testing.md §Structural Testing Contract](../docs/guide_testing.md) and the per-styleguide audit scripts in [code_styleguides/](code_styleguides/).
+
+- **Structural Testing Contract:** Ban on arbitrary core mocking with `unittest.mock.patch` (unless explicitly authorized for a specific boundary test). All integration and end-to-end testing must use the `live_gui` fixture to interact with a real instance of the application via the Hook API. Bypassing the hook server to directly mutate GUI state in tests is prohibited. All test-generated artifacts (logs, temporary workspaces, mock outputs) MUST be written to `tests/artifacts/` or `tests/logs/` (gitignored).
+- **Isolated-Pass Verification Fallacy (Added 2026-06-10):** A test that "passes when run after test X but fails in isolation" is a **fragile test, not a fragile fixture**. The flip side is also true: a test that "passes in isolation but fails in batch" is failing — its failure is masked by isolation. The only verification that matters for `live_gui` tests (or any test that depends on shared subprocess state) is the **batch run** in the suite the test will ship in. Do NOT commit a fix that has only been verified in isolation. The 4-day test-hell saga of 2026-06-06 to 2026-06-10 was the result of agents committing fixes after isolated passes; the bisect required both directions and was only caught at the suite-level batch green on 2026-06-10. See [docs/reports/test_infrastructure_hardening_batch_green_20260610.md](../docs/reports/test_infrastructure_hardening_batch_green_20260610.md) for the full incident.
+- **Audit Scripts as CI Gates:** The 4 audit scripts (`check_test_toml_paths.py`, `audit_main_thread_imports.py`, `audit_weak_types.py`, `audit_no_models_config_io.py`) enforce the conventions above. They run as pre-commit/CI gates and exit non-zero on regression. New conventions must be paired with a new audit script per [conductor/workflow.md §Audit Script Policy](workflow.md).
+- **Skip Markers Are Documentation, Not Avoidance:** `@pytest.mark.skip(reason=...)` is a record of a known failure, not an escape from fixing the underlying bug. Skip markers are valid for opt-in integration tests (require external resources, env-var-gated) or features behind a feature flag. They are NOT valid for pre-existing failing tests, tests the agent doesn't understand, or racy assertions the agent doesn't want to debug. When you add a skip, document the underlying issue in `reason=` and commit with a follow-up note. See [conductor/workflow.md §Skip-Marker Policy](workflow.md).

+# TODO: Fix test_full_live_workflow race condition
+
+**Report:** `docs/reports/test_full_live_workflow_root_cause_20260608.md`
+**Failure reproducibility:** 100% in tier-3 batch, 0% in isolation
+**Status:** Tasks 1+2 SHIPPED (commit `6ecb31ea`); Tasks 3-7 remaining
+
+## Tasks (simple, ordered by ROI)
+
+### 1. [HIGH] Add deterministic signal endpoint ✅ SHIPPED (commit 6ecb31ea)
+- **What:** Add `GET /api/project_switch_status` returning `{"in_progress": bool, "path": str | null, "error": str | null}`.
+- **Where:** `src/api_hooks.py` (new handler) + `src/app_controller.py` (track `_project_switch_in_progress` + `_project_switch_error` state).
+- **Why:** Polling the project dict is fragile (returns stale state from prior tests). Polling a purpose-built signal is deterministic.
+- **Pattern:** See `src/api_hooks.py:336-363` (`/api/warmup_wait`) for the existing pattern of "block until condition, return final state".
+- **Acceptance:** Test polls `/api/project_switch_status` until `in_progress == False` and `path == expected` and `error is None`. Times out after 30s with clear error.
+- **Note on test fix:** The 2nd unit test (`test_get_project_switch_status_default_is_idle`) was originally written without mocking `_make_request`, so it leaked through to the live `live_gui` session and got the real `active_project_path` back. Fixed in same commit by adding `patch.object(client, "_make_request")` mock. The live test (`test_live_project_switch_status_endpoint_idle`) was also loosened: `path` can be `None` or `str` (a project may be loaded at session start).
+
+### 2. [HIGH] Reset project state in `_handle_reset_session` ✅ SHIPPED (commit 6ecb31ea) + REGRESSION FIXED (commit e0a3eb8c)
+- **What:** Add `self.project = {}; self.project_paths = []` at the start of `_handle_reset_session`. Do NOT clear `self.active_project_path`.
+- **Where:** `src/app_controller.py:3244-3296`.
+- **Why:** The session-scoped `live_gui` fixture shares the controller across 48 tests. Prior tests leave stale project state. The reset handler currently clears AI session but not project state.
+- **Acceptance:** After `client.click("btn_reset")` followed by the new project-creation click, the test sees a clean project state regardless of which tests ran before it in the tier-3 batch.
+- **Implementation note (commit 6ecb31ea):** Mirrors `__init__` default-project branch: creates a fresh `project_manager.default_project(reset_name)`, sets `active_project_path = ""`, `project_paths = []`, reinitializes workspace manager. 3 unit tests pass.
+- **Regression (discovered in commit 6ecb31ea, fixed in commit e0a3eb8c):** Setting `self.active_project_path = ""` caused `test_context_sim_live` to fail. Root cause: `_do_project_switch` calls `_flush_to_project()` which writes to `self.active_project_path` (raises `OSError` on empty path), and the `finally` block's `_switch_project(pending)` re-submitted the failed switch in an infinite loop. Status stuck at "switching to: ..." for 5+ seconds. Fix: keep `self.active_project_path` as-is. Only replace `self.project` (fresh default) and clear `self.project_paths`. The stale state is solved by replacing the project dict. Also removed the `WorkspaceManager(project_root=None)` reinit (not needed for the bug). 3 unit tests + 16 related regression tests pass. `test_full_live_workflow` passes in 10.19s in isolation.
+
+### 3. [MED] Replace `os.path.abspath("tests/artifacts/temp_project.toml")` with fixture-provided path
+- **What:** Have the `live_gui` fixture provide `temp_project_path` (str) derived from its own `temp_workspace` directory.
+- **Where:** `tests/conftest.py` (live_gui fixture) + `tests/test_live_workflow.py:50`.
+- **Why:** cwd-relative path is fragile; fixture-relative path is stable.
+- **Acceptance:** Test does `temp_project_path = live_gui_temp_project_path` (or accesses it as a fixture attribute). No more `os.path.abspath("tests/artifacts/...")`.
+
+### 4. [MED] Replace 10×1s blind poll with condition-based wait ✅ SHIPPED (commits a6605d98 + b6972c31)
+- **What:** Use the new `/api/project_switch_status` endpoint with `client.wait_for_project_switch(expected_path, timeout)`.
+- **Where:** `tests/test_live_workflow.py` + new `ApiHookClient.wait_for_project_switch` method.
+- **Why:** Blind polling of derived state is fragile; condition-based wait is deterministic and surfaces the failure reason immediately.
+- **Pattern:** See `src/api_hook_client.py:wait_for_server` (existing pattern in the same client).
+- **Acceptance:** Test fails fast (within 30s) with a clear `error` message from the API instead of timing out at 10s with "Project failed to activate". 7 unit tests for the new helper (mocked _make_request) all pass.
+- **Known issue (still open):** Test STILL fails in tier-3-live_gui batch (passes in 10.24s in isolation). The wait helper reports `in_progress: True, path: temp_project.toml` for the full 30s timeout. Investigation found:
+  - Added pre-wait (`client.wait_for_project_switch` at start) so the test waits for any prior switch to complete
+  - Added `_handle_reset_session` to also clear `_project_switch_in_progress`/`_project_switch_pending_path`/`_project_switch_error` so a hung switch doesn't block the next session
+  - The new switch is submitted to io_pool but the `_do_project_switch` background thread is **still hanging in the batch context** for 30+ seconds. The thread is not blocked on a lock or I/O — it's just not being scheduled (likely io_pool saturation from prior sims' long-running discussion turn workers)
+  - This is a deeper issue: `test_extended_sims.py` sims each submit AI discussion turns that spawn multiple io_pool jobs. The sims don't wait for these to complete. The next test inherits a saturated pool.
+  - **Recommended fix:** Mark `test_full_live_workflow` with `@pytest.mark.skipif(ENV_BATCH)` or run it in a separate subprocess. The test is fundamentally fragile to session-scoped state pollution and the io_pool saturation from prior sims.
+
+### 5. [LOW] Add defensive state assertions ✅ SHIPPED (commit b6972c31)
+- **What:** Before waiting for activation, verify the file was created (5s poll, then assert).
+- **Where:** `tests/test_live_workflow.py:55-65`.
+- **Why:** Catches the case where the click was dropped or the handler crashed before writing the file.
+- **Acceptance:** If the file doesn't exist within 5s, the test fails immediately with "temp_project.toml not created within 5s of click". (The `client.get_events()` check is not implemented; the file existence check is the primary signal.)
+- **Verified:** Defensive check passes in both isolation and batch (file IS created). The batch failure is downstream of this check (in `_do_project_switch` background thread).
+
+### 6. [LOW] Add `pytest.mark.live` to pyproject.toml markers
+- **What:** Append `"live: marks tests as live visualization tests (not in CI by default)"` to `[tool.pytest.ini_options].markers`.
+- **Where:** `pyproject.toml`.
+- **Why:** Silences the `PytestUnknownMarkWarning: Unknown pytest.mark.live` warnings emitted by `test_visual_mma.py`, `test_visual_sim_gui_ux.py`. The mark already exists; pyproject just doesn't know about it.
+- **Acceptance:** `uv run pytest tests/ 2>&1 | grep -i UnknownMark` returns 0 lines.
+
+### 7. [LOW] Add `tests/.test_durations.json` recording in CI / dev convenience
+- **What:** Add a dev-mode shortcut to record durations once the fix lands (e.g. `python scripts/run_tests_batched.py --durations`).
+- **Where:** `scripts/run_tests_batched.py` already has `--durations` flag; just need a one-time run + commit.
+- **Why:** The categorizer uses `.test_durations.json` for `speed` auto-inference. Currently all files default to MEDIUM speed.
+- **Acceptance:** `tests/.test_durations.json` exists, has timing data for all 295+ tests. (Not strictly needed for the live_workflow fix.)
+
+## Order of work
+
+1, 2, 3, 4 are tightly coupled (all about making the test deterministic and isolated). Do them in one PR.
+
+5 is a defensive complement. Add with 1-4.
+
+6, 7 are unrelated cleanup. Do in a separate small commit.
+
+## Estimated time
+
+- Tasks 1, 2, 3, 4, 5: 2-3 hours (mostly test + 1 endpoint + 1 reset path)
+- Tasks 6, 7: 5-10 minutes each
+
+## Verification
+
+After fix:
+- `uv run python scripts/run_tests_batched.py --tiers 3 --no-xdist --no-color` shows `<<< tier-3-live_gui PASS`
+- `uv run pytest tests/test_live_workflow.py` still PASSes in isolation
+- `uv run pytest tests/test_live_workflow.py tests/test_extended_sims.py tests/test_command_palette_sim.py` (siblings) PASSes
+- Failure message on real regression is clear and actionable (e.g. "click was not dispatched within 5s" or "/api/project_switch_status returned error: file not found")

+# TODO: Fix test_full_live_workflow — ImGui IM_ASSERT root cause + batch resilience
+
+**Report:** `docs/reports/test_full_live_workflow_imgui_assert_20260608.md` (v2, supersedes v1)
+**Predecessor:** `conductor/todos/TODO_test_full_live_workflow.md` (Tasks 1, 2, 4, 5, 6 SHIPPED; Tasks 3, 7 remaining and still relevant)
+**Status:** NEW. No tasks started. Awaiting user direction on which solution to implement first.
+**Failure reproducibility:** 100% in tier-3 batch (5+ live_gui tests, ~200s total), 0% in isolation
+
+---
+
+## The Real Root Cause (per v2 report)
+
+The test's `_do_project_switch` runs in ~8-10ms — it is NOT slow. The test fails because:
+
+1. Some `render_*` function has an ImGui scope mismatch (`begin()` without matching `end()`)
+2. After 4 sims have rendered their panels, the cumulative state triggers an `IM_ASSERT((0) && "Missing End()")` from imgui.cpp:11662 in window 'MainDockSpace' at frame ~71.5s into GUI lifetime
+3. The `RuntimeError` from `immapp.run` propagates up through `app.run()` and `main()`
+4. The exception causes the controller's `_io_pool` to shut down (likely via `ThreadPoolExecutor.__del__` during GC, or via the `app.shutdown()` path if `immapp.run` internally caught and returned)
+5. The hook server thread keeps running (it's a separate `ThreadingHTTPServer` in `src/api_hooks.py`)
+6. The test's `btn_project_new_automated` click hits the click handler, which calls `submit_io(self._do_project_switch, path)`, which throws `RuntimeError: cannot schedule new futures after shutdown`
+7. The test's `wait_for_project_switch` polls `/api/project_switch_status` 1200+ times in 120s and times out
+
+The `_do_project_switch` is a symptom, not the cause.
+
+---
+
+## Tasks (ordered by dependency)
+
+### 1. [HIGH] Run `scripts/check_imgui_scopes.py` to identify the scope mismatch
+
+- **What:** Invoke the existing audit script against `src/gui_2.py` and any other ImGui-rendering files. Look for `begin()` calls without a matching `end()` in the same scope.
+- **Where:** `scripts/check_imgui_scopes.py` (existing), `src/gui_2.py` (90+ render functions).
+- **Why:** This is the real fix. The script exists for exactly this purpose but hasn't been run against the recent render additions.
+- **Pattern:** Per `conductor/workflow.md`: "Mandatory ImGui Verification: All changes to the GUI (gui_2.py) MUST be verified using the custom AST linter (scripts/check_imgui_scopes.py) to ensure all ImGui scopes (begin/end, push/pop) are properly matched."
+- **Acceptance:** Audit output identifies the specific `render_*` function and line number(s) with the unbalanced scope. Documented in the report.
+- **Effort:** 1-2 hours (audit run + manual triage of findings).
+- **Risk:** Medium. Findings may be in render paths that are only exercised by specific sim combinations. Need careful triage.
+
+### 2. [HIGH] Fix the identified ImGui scope mismatch
+
+- **What:** Once Task 1 identifies the function, add the missing `end()` (or remove the spurious `begin()`).
+- **Where:** TBD by Task 1. Likely in a `render_*` function called from `_gui_func` → `_render_main_interface` → some panel.
+- **Why:** This is the actual bug. All other tasks are workarounds.
+- **Acceptance:**
+  - `IM_ASSERT` no longer fires in any test batch combination
+  - All existing tests still pass (no regression)
+  - `test_full_live_workflow` passes in tier-3 batch (the goal)
+- **Effort:** 1-4 hours depending on what Task 1 finds.
+- **Risk:** Medium. A wrong fix could break other tests. May need to add defer-not-catch pattern (per `conductor/workflow.md` known pitfall) for the offending render path.
+- **Depends on:** Task 1.
+
+### 3. [MED] Wrap `immapp.run` in `try/except RuntimeError` in `gui_2.py:618`
+
+- **What:** Catch the IM_ASSERT (or any `RuntimeError` from `immapp.run`), log it, and return gracefully so the process doesn't die.
+- **Where:** `src/gui_2.py:618`.
+- **Why:** Per user: "the wrap might be worth it if that properly lets us handle the assert." A proper wrap logs the assert, marks the GUI as degraded, and lets the hook server keep serving (so tests can complete their work). It is NOT a silent swallow — the error is logged at ERROR level and exposed via a new endpoint.
+- **Acceptance:**
+  - When IM_ASSERT fires, the subprocess stays alive
+  - The `_io_pool` is NOT shut down by the exception (or is re-created lazily — see Task 5)
+  - A new `/api/gui_health` endpoint returns `{"degraded": true, "last_assert": "..."}` so tests can detect the state
+  - The log includes the full assert message + stack trace at ERROR level
+- **Effort:** 1-2 hours. The wrap is simple. The endpoint + logging is straightforward.
+- **Risk:** Low. The wrap is a band-aid, but it properly handles the failure (logs it, surfaces it) rather than swallowing silently.
+- **Depends on:** None. Can be done in parallel with Tasks 1+2. Belongs in the same PR as the fix or as a separate hardening PR.
+
+### 4. [MED] Add batch-level test isolation (kill+restart sloppy.py per file)
+
+- **What:** Modify `scripts/run_tests_batched.py` to kill the `live_gui` subprocess at the end of each test file (or at the start of a new one), so a failing test file doesn't poison subsequent test files.
+- **Where:** `scripts/run_tests_batched.py` (existing batch runner).
+- **Why:** Per user: "I also don't want a batch to be too fragile where I can't restart the app and continue with the next test file if it fails. Just has to note that the new file didn't get to deal with a dirty state."
+- **Pattern:** A failing batch should not block subsequent batches. The user wants to be able to run a batch, see it fail, run the next batch, and have it start clean.
+- **Acceptance:**
+  - When a test file fails, the runner logs a clear "batch N failed; next batch will restart the app" message
+  - The next batch's `live_gui` fixture spawns a fresh `sloppy.py` subprocess (or detects the old one is dead and spawns a new one)
+  - No "dirty state" from a prior failed batch leaks into the next batch
+  - The batch runner continues to the next batch automatically (no user intervention needed)
+- **Effort:** 2-4 hours. Requires understanding the current batch runner's lifecycle and modifying the `live_gui` fixture to handle "previous subprocess died, start a new one".
+- **Risk:** Low. The conftest's `live_gui` fixture is already session-scoped — making it per-file-scoped (or function-scoped with batch-aware session reuse) is a small change.
+- **Depends on:** None. Can be done in parallel with the other tasks.
+
+### 5. [LOW] Make `submit_io` recover from a shut-down pool
+
+- **What:** In `submit_io`, if `self._io_pool` is shut down, recreate it lazily.
+- **Where:** `src/app_controller.py:2257-2284` (current `submit_io` body).
+- **Why:** Defense in depth. If the GUI crashes and shuts down the pool, the test can still submit work after the wrap (Task 3) catches the exception. Without this, the controller is permanently dead.
+- **Acceptance:**
+  - After a GUI crash + `immapp.run` recovery, `submit_io` works again
+  - No new threading issues (the recreated pool has the same semantics)
+  - Inflight counter (`_io_pool_inflight`) is reset
+- **Effort:** 30 minutes.
+- **Risk:** Low. Standard lazy-recreation pattern. The pool was already designed to be replaceable.
+- **Depends on:** None.
+
+### 6. [LOW] Add `/api/gui_health` endpoint with degraded-state info
+
+- **What:** New endpoint returning `{"healthy": bool, "degraded_reason": str | null, "last_assert": str | null, "io_pool_alive": bool}`.
+- **Where:** `src/api_hooks.py` (add new `elif` branch) + `src/app_controller.py` (add `self._gui_degraded_reason` and `self._last_imgui_assert` state).
+- **Why:** Per Task 3, the wrap logs the assert. The endpoint exposes the state to tests so they can detect a degraded GUI and fail with a clear message ("GUI is degraded due to IM_ASSERT; skipping test") rather than a confusing timeout.
+- **Acceptance:**
+  - Endpoint returns 200 with the health dict
+  - Tests can call `client.get_gui_health()` and check `healthy == False` to detect a degraded GUI
+  - `tests/test_live_workflow.py` checks the health before starting and fails fast with a clear message if degraded
+- **Effort:** 1-2 hours.
+- **Risk:** Low. Read-only endpoint.
+- **Depends on:** Task 3.

+
+## Tasks Inherited from Predecessor TODO (still relevant)
+
+These are from `conductor/todos/TODO_test_full_live_workflow.md` and were marked as not yet shipped:
+
+### 7. [MED] Replace `os.path.abspath("tests/artifacts/temp_project.toml")` with fixture-provided path
+
+- **What:** Have the `live_gui` fixture provide `temp_project_path` (str) derived from its own `temp_workspace` directory.
+- **Where:** `tests/conftest.py` (live_gui fixture) + `tests/test_live_workflow.py:79`.
+- **Why:** cwd-relative path is fragile; fixture-relative path is stable. Per the v1 report's Cause 1.
+- **Acceptance:** Test does `temp_project_path = live_gui_temp_project_path` (or accesses it as a fixture attribute). No more `os.path.abspath("tests/artifacts/...")`.
+- **Effort:** 30 minutes.
+- **Risk:** Low.
+
+### 8. [LOW] Add `tests/.test_durations.json` recording in CI / dev convenience
+
+- **What:** Add a dev-mode shortcut to record durations once the fix lands (e.g. `python scripts/run_tests_batched.py --durations`).
+- **Where:** `scripts/run_tests_batched.py` (already has `--durations` flag; just need a one-time run + commit).
+- **Why:** The categorizer uses `.test_durations.json` for `speed` auto-inference. Currently all files default to MEDIUM speed.
+- **Acceptance:** `tests/.test_durations.json` exists, has timing data for all 295+ tests.
+- **Effort:** 5 minutes (run + commit).
+- **Risk:** Low.
+
+### 9. [HIGH] Ensure required test deps are in [dependency-groups].dev + conftest gate
+
+**STATUS: SHIPPED 2026-06-09 (commit a341d7a7)**
+
+- **What:** Add session-start gate in `tests/conftest.py` that fails fast with a clear, actionable error if a required test dep is missing. Move `sentence-transformers` from `[project.optional-dependencies].local-rag` to `[dependency-groups].dev` so a normal `uv sync` pulls it in.
+- **Where:** `tests/conftest.py` (added `pytest_configure` + `_check_required_test_dependencies`), `pyproject.toml:34-41` (added dep to dev), `tests/test_required_test_dependencies.py` (new TDD test).
+- **Why:** The RAG batch failure was environment-dependent. The test required `sentence-transformers` unconditionally (sets `rag_emb_provider='local'`), but the dep was in optional extras so a fresh `uv sync` (no `--extra`) left the test env without it. The failure mode was a confusing 80s batch failure with no clear fix. The gate prevents future incidents of this class.
+- **Acceptance:**
+  - `uv sync` (no extras) installs the dep
+  - `uv run pytest` at session start runs `_check_required_test_dependencies` via `pytest_configure`
+  - If a required dep is missing, the session fails with: "Required test dependencies are missing from the venv: ... Fix: uv sync --extra local-rag"
+  - 22 unit tests pass (gate test + RAG status tests + io_pool + warmup + gui_health)
+  - 4 sims pass (no conftest regression)
+- **Effort:** DONE.
+- **Risk:** Low. The dep is in dev so the gate is a no-op for normal `uv run pytest` usage. The gate is a HARD fail (not a soft skip) per the user's "no skip markers" constraint.
+
+---
+
+## Order of Work (recommended)
+
+1. **Tasks 1 + 2 first** — find and fix the ImGui scope mismatch. This is the real fix. If successful, Tasks 3, 4, 5, 6 may be unnecessary (or become hardening improvements rather than bug fixes).
+2. **Task 3 in parallel** — wrap `immapp.run` so the assert doesn't kill the process. Even if Task 2 succeeds, the wrap is a good safety net for future scope bugs.
+3. **Task 4** — batch-level isolation. Independent of the ImGui fix; improves robustness for ALL tests.
+4. **Tasks 5, 6** — defense in depth. Only valuable if Tasks 1+2 don't fully fix the issue OR as ongoing hardening.
+5. **Tasks 7, 8** — unrelated cleanup. Do in a separate small commit/PR.
+
+## Estimated Time
+
+- Tasks 1+2: 2-6 hours (real fix, may require investigation)
+- Task 3: 1-2 hours (band-aid, but proper one)
+- Task 4: 2-4 hours (batch resilience)
+- Tasks 5+6: 1-2 hours combined (defense in depth)
+- Tasks 7+8: 30 minutes combined (cleanup)
+- **Total: 6-14 hours**
+
+## Verification
+
+After fix:
+- `uv run python scripts/run_tests_batched.py --tiers 3 --no-xdist --no-color` shows `<<< tier-3-live_gui PASS`
+- `uv run pytest tests/test_live_workflow.py` still PASSes in isolation
+- `uv run pytest tests/test_live_workflow.py tests/test_extended_sims.py` (siblings) PASSes
+- A failing batch does NOT prevent the next batch from running with a clean state
+- Failure message on real regression is clear and actionable (e.g. "GUI degraded: IM_ASSERT(Missing End()) in render_X; skipping test")

+This file tracks all major tracks for the project. Each track has its own detailed plan in its respective folder (or in `../archive/<track_name>/` for completed tracks).
+
+**Structure:**
+- **Active Tracks (Current Queue):** In-flight and unblocked work the implementer can pick up today.
+- **Phase 0 - 9 (Chronological):** The full project history in chronological order. Each phase has three sub-sections: **Active** (work in progress), **Completed** (work shipped but track not yet archived), **Archived** (track folder moved to `archive/`).

-   *Goal: Resolve five long-standing UI issues:
-   - Phase 1: GFM markdown table rendering (pre-processor into `src/markdown_table.py`, wire into `MarkdownRenderer.render`).
-   - Phase 2: Widen the `Keep Pairs` numeric input next to `Truncate` in the discussion panel (`gui_2.py:3829`, width 80 -> 140, switch to `drag_int`).
-   - Phase 3: Fix `Refresh Registry` button in Log Management — currently instantiates `LogRegistry` without calling `load_registry()` so the displayed table never reflects on-disk state (`gui_2.py:1675`).
-   - Phase 4: Add `Vendor State` tab to Operations Hub — at-a-glance provider/model, context-window utilization, cache hit rate, last error class, vendor quota (new `src/vendor_state.py` aggregator + `controller.vendor_quota` field + `ai_client` wire-up).
-   - Phase 5: Files & Media > Files directory-grouped tree (re-use `aggregate.group_files_by_dir`, mirror `render_context_files_table` collapsible-node style).*

-   *Goal: Reduce sloppy.py startup time. Main Thread Purity Invariant. 9 phases, 57 tasks. 44 TDD tests added (all passing). 7 main thread purity tests enforce invariant for 6 refactored files.*
-   *Final measured: import src.ai_client 161ms (was 1800ms; 91% reduction / 1638ms saved). import src.gui_2 341ms (was 1770ms; 81% reduction / 1429ms saved). Total ~3067ms saved on the 2 big files. 62 audit violations remain (was 63 after Sub-track 2 partial; was 67 baseline) - all 6 refactored files contribute 0 new violations.*
-   *Sub-track 1 (Phase 6 full completion) at 253e1798: 15 ad-hoc threading.Thread() call sites migrated to self.submit_io(...); ZERO new threading.Thread() in src/; only 5 domain-specific exempt sites remain (HookServer HTTP/WS, asyncio loop, WorkerPool, CPU monitor).*
-   *Sub-track 3 (Hook API warmup endpoints) at 8fea8fe9: GET /api/warmup_status and GET /api/warmup_wait?timeout=N. 7 tests (5 unit + 2 live_gui). All pass.*
-   *Sub-track 4 (GUI status indicator) at f3d071e0: render_warmup_status_indicator() + _on_warmup_complete_callback() + App._post_init registration. 6 tests (5 unit + 1 live_gui). All pass.*
-   *Conftest atexit fix at 8957c9a5: registers a non-blocking pool shutdown via atexit. Fixes the run_tests_batched.py hang between batches (ThreadPoolExecutor.__del__ was blocking on shutdown(wait=True) for stuck warmup jobs).*
-   *Sub-track 2 (audit violations) PARTIAL at ae3b433e: 1 of 63 violations fixed (tomli_w in src/models.py). 62 remain (pydantic in models.py; tree_sitter in file_cache.py; websockets/cost_tracker/session_logger in api_hooks.py; 48 in app_controller.py + gui_2.py; 4 in sloppy.py). These are large refactors (especially gui_2.py with 24 violations and app_controller.py with 24) that exceed the scope of a single sub-track; addressed as future work.*
-   *3 post-shipping bugfix commits: 8c4791d0 (real bug: _ensure_gemini_client UnboundLocalError + test_discussion_compression deepseek mock adaptation); 88fc42bb (spec convention: 7 sites in src/ai_client.py use _require_warmed('google.genai') + .types parent lookup instead of leaf); 52ea2693 (conftest: use AppController.wait_for_warmup(timeout=60.0) instead of direct import google.genai — user-corrected jank workaround).*

Hybrid classification: auto-infer from filename + AST fixture scan, hand-curated `tests/test_categories.toml` overrides for cross-cutting and ambiguous files. Opt-in per-test order control via `[[files.X.test_order]]` sub-tables, gated on a conftest-loaded pytest plugin (no-op without entries). Priority: B (process isolation) > A (subsystem diagnostic) > C (speed). 4 phases: library+dry-run, shadow run, switch default, cleanup.*
-   *Goal: Reduce `sloppy.py` startup time by ~2000-2400ms. **Main Thread Purity Invariant**: main thread (entering `immapp.run()`) never imports a module heavier than `imgui_bundle` + lean `gui_2` skeleton. **No-prefetch rule**: heavy SDKs (`google.genai` 955ms, `anthropic` 430ms, `openai` 445ms, `fastapi` 470ms) are lazy-only — paid once on first use, on the asyncio thread, not in the background. **No-new-threads rule**: all background work goes through `AppController._io_pool` (4-thread `ThreadPoolExecutor`, named `controller-io-N`); zero new `threading.Thread(...)` calls in `src/`. **Enforcement**: static `scripts/audit_main_thread_imports.py` CI gate + runtime `tests/test_main_thread_purity.py` (`sys.addaudithook` test). 9 phases, 57 tasks. Target: `import src.ai_client` < 50ms (from ~1800ms), `import src.gui_2` < 500ms (from ~3000ms), `live_gui.wait_for_server(timeout=15)` no longer times out.*
 
-0d. [ ] **Track: Qwen, Llama & Grok Vendor Integration + Capability Matrix** `[track-created: 7c1d597e]`
+Tracks 1 - 29 of the original Phase 4 archive (preserved with original numbers for cross-reference continuity):
-   *Link: [./tracks/qwen_llama_grok_integration_20260606/](./tracks/qwen_llama_grok_integration_20260606/), Spec: [./tracks/qwen_llama_grok_integration_20260606/spec.md](./tracks/qwen_llama_grok_integration_20260606/spec.md), Plan: [./tracks/qwen_llama_grok_integration_20260606/plan.md](./tracks/qwen_llama_grok_integration_20260606/plan.md) (to be authored by writing-plans skill)*
-   *Goal: Add first-class support for Qwen (DashScope native SDK), Llama (Ollama local + OpenRouter cloud + custom URL), and Grok (xAI OpenAI-compatible). Introduce a **Vendor Capability Matrix** (7 v1 capabilities: vision, tool_calling, caching, streaming, model_discovery, context_window, cost_tracking; audio and server-side code_execution deferred) declared per-(vendor, model) in `src/vendor_capabilities.py`. GUI reads the matrix to enable/disable 9 UI elements (screenshot button, tools toggle, cache panel, stream progress, fetch models, token budget, cost panel) instead of hard-coding per-vendor branches. Extract a shared `send_openai_compatible()` helper in `src/openai_compatible.py` that operates on a normalized request/response data structure; each `_send_<vendor>()` is a thin boundary adapter (data-oriented design per Fleury/Acton/Lottes). Refactor `_send_minimax()` to use the helper (~250 lines → ~50). **Out of scope** (separate follow-up track): Anthropic/Gemini/DeepSeek migration to the matrix. 6 phases: matrix+helper, Qwen, Grok+Llama, MiniMax refactor, UX adaptation, docs+archive.*
-
-0e. [ ] **Track: Data-Oriented Error Handling (Fleury Pattern)** `[track-created: 494f68f9]`
-   *Link: [./tracks/data_oriented_error_handling_20260606/](./tracks/data_oriented_error_handling_20260606/), Spec: [./tracks/data_oriented_error_handling_20260606/spec.md](./tracks/data_oriented_error_handling_20260606/spec.md), Plan: [./tracks/data_oriented_error_handling_20260606/plan.md](./tracks/data_oriented_error_handling_20260606/plan.md) (to be authored by writing-plans skill)*
-   *Goal: Introduce Ryan Fleury's "errors are just cases" framework as a project convention. New `src/result_types.py` (ErrorKind enum, ErrorInfo dataclass, `Result[T]` with data + side-channel errors list, NilPath + NilRAGState sentinel singletons) and new `conductor/code_styleguides/error_handling.md` canonical reference. Refactor `src/mcp_client.py` ((p, err) tuples → Result; 30+ `assert p is not None` → nil-sentinel paths), `src/ai_client.py` (ProviderError exception → ErrorInfo dataclass; `_send_<vendor>()` → `_send_<vendor>_result()` returning `Result[str]`; `send()` marked `@deprecated`; new `send_result()` public API), and `src/rag_engine.py` (RAGEngine methods → Result returns). Update `conductor/product-guidelines.md` + `workflow.md` + `docs/guide_*.md` so the convention is documented and future plans can incrementally migrate the remaining `src/` files. **Blocked by** startup_speedup, test_batching_refactor, and qwen_llama_grok tracks. 5 phases: foundation+styleguide, mcp_client refactor, ai_client refactor (highest risk; ProviderError removal), rag_engine refactor, deprecation+docs+archive.*
-   *Follow-up: [./tracks/public_api_migration_20260606/](./tracks/public_api_migration_20260606/) (planned; not yet specced) — removes the deprecated `ai_client.send()` and migrates all callers.*
-
-0f. [ ] **Track: Data Structure Strengthening (Type Aliases + NamedTuples)** `[track-created: ed42a97a]`
-   *Link: [./tracks/data_structure_strengthening_20260606/](./tracks/data_structure_strengthening_20260606/), Spec: [./tracks/data_structure_strengthening_20260606/spec.md](./tracks/data_structure_strengthening_20260606/spec.md), Plan: [./tracks/data_structure_strengthening_20260606/plan.md](./tracks/data_structure_strengthening_20260606/plan.md) (to be authored by writing-plans skill)*
-   *Goal: Improve AI-readability by naming 430 currently-anonymous `dict[str, Any]` / `list[dict[...]]` / `Tuple[...]` types. New `src/type_aliases.py` with 10 `TypeAlias` definitions (`Metadata`, `CommsLogEntry`, `CommsLog`, `HistoryMessage`, `History`, `FileItem`, `FileItems`, `ToolDefinition`, `ToolCall`, `CommsLogCallback`) and 1 `NamedTuple` (`FileItemsDiff`). Mechanical replacement of 345 weak sites across 6 high-traffic files: `src/ai_client.py` (139), `src/app_controller.py` (86), `src/models.py` (51), `src/api_hook_client.py` (32), `src/project_manager.py` (20), `src/aggregate.py` (17). Add `--strict` mode to the existing `scripts/audit_weak_types.py` (committed in 84fd9ac9; found the 430 sites) so it becomes a permanent CI gate that fails when new weak types are introduced. Generate `scripts/audit_weak_types.baseline.json` with the post-refactor count. 2 phases: aliases + 6-file replacement + audit baseline; NamedTuples + docs + archive. **Data-grounded**: the audit script is the source of truth; the count drops from 430 to ~60 (86% reduction) in the 6 high-traffic files. **Honest about what's missing**: 23 lower-impact files remain; TypedDict/dataclass migration is deferred to a follow-up track. 2-3 days work, 1-2 phases, low risk.*

-0g. [ ] **Track: MCP Architecture Refactor (Sub-MCP Extraction)** `[track-created: 2720a894]`
-   *Link: [./tracks/mcp_architecture_refactor_20260606/](./tracks/mcp_architecture_refactor_20260606/), Spec: [./tracks/mcp_architecture_refactor_20260606/spec.md](./tracks/mcp_architecture_refactor_20260606/spec.md), Plan: [./tracks/mcp_architecture_refactor_20260606/plan.md](./tracks/mcp_architecture_refactor_20260606/plan.md) (to be authored by writing-plans skill)*
-   *Goal: Split the 2,205-line monolithic `src/mcp_client.py` (45 module-level functions) into a slim controller + 6 native sub-MCPs + 1 external sub-MCP. Naming convention `mcp_<type>.py` for native MCPs: `mcp_file_io.py` (9 tools), `mcp_python.py` (14), `mcp_c.py` (5), `mcp_cpp.py` (5), `mcp_web.py` (2), `mcp_analysis.py` (2). The existing `ExternalMCPManager` is extracted to `mcp_external.py` (class name preserved). New `MCPController` class in `src/mcp_client.py` holds the 3-layer security model (extracted to `src/mcp_client_security.py`), the `ALL_SUB_MCPS` registration list, and the inverted-dict dispatch lookup. New `src/mcp_client_legacy.py` re-exports all 45+ old symbols for backward compat (the 4 existing test files + `src/app_controller.py:61` continue to work). Each sub-MCP's `invoke()` returns `Result[str, ErrorInfo]` (Fleury pattern). Path parameters use the `Metadata` family aliases. **Blocked by** `data_oriented_error_handling_20260606` (for `Result`/`ErrorInfo`) and `data_structure_strengthening_20260606` (for `Metadata` aliases). 7 phases: foundation (security + controller), move-to-legacy, extract File I/O, extract Python, extract C/C++/Web/Analysis, extract External, dispatch update + docs + archive. **Out of scope** (per user): a per-MCP DSL (APL/K/Cosy-inspired) for compact tool calls — deferred to `mcp_dsl_20260606` follow-up. JSON-only for now.*

-0b. [x] **Track: rag_phase4_stress_test_flake_20260606** — fixed 16412ad5
-   *Status: 2026-06-06 — Surfaced during post-v2 verification. Resolved: real bug, NOT a test flake. Root cause: ChromaDB collection dimension mismatch across test runs. The persistent on-disk collection (`tests/artifacts/live_gui_workspace/.slop_cache/chroma_test_stress/`) was created by a previous run with Gemini embeddings (3072-dim); the current run uses local SentenceTransformers (384-dim). `index_file()` upserts silently corrupt the collection, then `search()` fails with `Collection expecting embedding with dimension of 3072, got 384` and the AI request never reaches 'done' status, timing out the 50*0.5s = 25s poll loop. Fix: `RAGEngine._init_vector_store` now calls `_validate_collection_dim` which inspects the first existing vector's dim, compares to the current provider's output, and recreates the collection on mismatch (with a stderr warning). Regression tests added: `test_rag_collection_dim_mismatch_recreates_collection` and `test_rag_collection_dim_match_preserves_collection` in `tests/test_rag_engine.py`. This also fixes a real user-facing bug: switching embedding providers in the GUI previously caused silent corruption. Commit 16412ad5.*
-0a. [ ] **Track: prior_session_test_harden_20260605** [superseded by live_gui_test_hardening_v2_20260605]
-   *Status: 2026-06-05 — Surfaced during live_gui_fragility_fixes_20260605 execution. `test_prior_session_no_pop_imbalance::test_no_extraneous_pop_when_prior_session_renders` is more under-mocked than expected. Completed as part of live_gui_test_hardening_v2_20260605: test refactored to call narrow render_prior_session_view (50+ mocks -> 20, runtime 5.79s -> 0.08s). Commit 26e0ced4.*

+   *Goal: Resolve five long-standing UI issues:
+   - Phase 1: GFM markdown table rendering (pre-processor into `src/markdown_table.py`, wire into `MarkdownRenderer.render`).
+   - Phase 2: Widen the `Keep Pairs` numeric input next to `Truncate` in the discussion panel (`gui_2.py:3829`, width 80 -> 140, switch to `drag_int`).
+   - Phase 3: Fix `Refresh Registry` button in Log Management — currently instantiates `LogRegistry` without calling `load_registry()` so the displayed table never reflects on-disk state (`gui_2.py:1675`).
+   - Phase 4: Add `Vendor State` tab to Operations Hub — at-a-glance provider/model, context-window utilization, cache hit rate, last error class, vendor quota (new `src/vendor_state.py` aggregator + `controller.vendor_quota` field + `ai_client` wire-up).
+   - Phase 5: Files & Media > Files directory-grouped tree (re-use `aggregate.group_files_by_dir`, mirror `render_context_files_table` collapsible-node style).*

Catches "works on my machine" failures. Added `clean_install` marker to `pyproject.toml`. Created `tests/test_clean_install.py` (114 lines, uses `urllib.request` from stdlib per tech-stack.md dependency minimalism rule - deviation from plan). Skipped by default.

   *Goal: Resolve the 3 remaining live_gui failures (269/272 → 271/272 plus 1 new regression unit test). 1-line src fix in `_capture_workspace_profile` (change `ini=b""` to `ini=""` to satisfy `WorkspaceProfile.ini_content: str` contract that `tomli_w` enforces); the `b""` sentinel was a regression from `d7487af4` that caused `save_workspace_profile` to raise `TypeError`, profile never saved, `load_workspace_profile` became a no-op. 1 new unit test (`tests/test_workspace_profile_serialization.py`) encoding the str/bytes contract. `test_prior_session_no_pop_imbalance` is **deferred to a separate follow-up track** — the test was more under-mocked than the spec assumed; fixing imscope.window tuple-return only revealed the next un-mocked dependency (imgui.begin returning bool where 2-tuple expected at line 4496). `render_main_interface` is a kitchen-sink function requiring 50+ mocks; a follow-up track will either add the missing mocks or refactor the test to exercise a narrow prior-session render path. Change 4 (doc hardening of defer-not-catch sections) deferred to track end; not done due to scope focus.*

The App class had _capture_workspace_profile being parsed as nested inside _apply_snapshot due to indentation. Once fixed, 3 tests (test_auto_switch_sim, test_workspace_profiles_restoration, test_undo_redo_lifecycle) immediately passed. App/Controller state sync is already correctly handled by __getattr__/__setattr__ at lines 478-487.*

-*Failing tests:*
+---
-- `test_auto_switch_sim` (still fails from v1) - **Deeper bug: App/Controller state sync**. The test does `set_value('ui_separate_tier1', True)` which goes to `controller.ui_separate_tier1`, but the save reads from `app.ui_separate_tier1`. Two different objects; the saved profile has the wrong value. Same root cause for `show_windows['Diagnostics']`.
+
-- `test_workspace_profiles_restoration` (still fails from v1) - same App/Controller sync bug.
+## Phase 6+ (Active Sprint): Performance, Vendor Coverage, Error Handling, MCP Refactor (2026-06-06+)
-- `test_prior_session_no_pop_imbalance` (deferred from v1) - `render_main_interface` is a kitchen-sink function requiring 50+ mocks; needs refactor or extensive mock additions.
+
-- `test_undo_redo_lifecycle` (NEW regression) - undo restores `temperature` correctly but `ai_input` is empty string instead of "Initial Input". Snapshot mechanism probably doesn't include `ai_input` field.
+*Initialized: 2026-06-06 — the current major sprint. Four foundational tracks launched in this sprint, plus one follow-up. **As of 2026-06-10: 3 recently completed (startup_speedup, test_batching_refactor, test_infrastructure_hardening); 4 in plan state (qwen, error_handling, data_structure, mcp_arch).** The 4 in-plan tracks are now unblocked (the upstream test_infrastructure_hardening track is shipped).*

+
+*Goal: Add first-class support for Qwen (DashScope native SDK), Llama (Ollama local + OpenRouter cloud + custom URL), and Grok (xAI OpenAI-compatible). Introduce a **Vendor Capability Matrix** (7 v1 capabilities: vision, tool_calling, caching, streaming, model_discovery, context_window, cost_tracking; audio and server-side code_execution deferred) declared per-(vendor, model) in `src/vendor_capabilities.py`. GUI reads the matrix to enable/disable 9 UI elements (screenshot button, tools toggle, cache panel, stream progress, fetch models, token budget, cost panel) instead of hard-coding per-vendor branches. Extract a shared `send_openai_compatible()` helper in `src/openai_compatible.py` that operates on a normalized request/response data structure; each `_send_<vendor>()` is a thin boundary adapter (data-oriented design per Fleury/Acton/Lottes). Refactor `_send_minimax()` to use the helper (~250 lines → ~50). **Out of scope** (separate follow-up track): Anthropic/Gemini/DeepSeek migration to the matrix. 6 phases: matrix+helper, Qwen, Grok+Llama, MiniMax refactor, UX adaptation, docs+archive. **Now blocked by** test_infrastructure_hardening_20260609 (was: none).*

+
+*Goal: Introduce Ryan Fleury's "errors are just cases" framework as a project convention. New `src/result_types.py` (ErrorKind enum, ErrorInfo dataclass, `Result[T]` with data + side-channel errors list, NilPath + NilRAGState sentinel singletons) and new `conductor/code_styleguides/error_handling.md` canonical reference. Refactor `src/mcp_client.py` ((p, err) tuples → Result; 30+ `assert p is not None` → nil-sentinel paths), `src/ai_client.py` (ProviderError exception → ErrorInfo dataclass; `_send_<vendor>()` → `_send_<vendor>_result()` returning `Result[str]`; `send()` marked `@deprecated`; new `send_result()` public API), and `src/rag_engine.py` (RAGEngine methods → Result returns). Update `conductor/product-guidelines.md` + `workflow.md` + `docs/guide_*.md` so the convention is documented and future plans can incrementally migrate the remaining `src/` files. **Blocked by** startup_speedup, test_batching_refactor, test_infrastructure_hardening_20260609, and qwen_llama_grok tracks. 5 phases: foundation+styleguide, mcp_client refactor, ai_client refactor (highest risk; ProviderError removal), rag_engine refactor, deprecation+docs+archive.*
+*Follow-up: **`public_api_migration_20260606`** (planned; not yet specced; no directory yet) — removes the deprecated `ai_client.send()` and migrates all callers. Detailed in the parent track's spec §12.1.*
+
+#### Track: Data Structure Strengthening (Type Aliases + NamedTuples) `[track-created: ed42a97a]`
+*Link: [./tracks/data_structure_strengthening_20260606/](./tracks/data_structure_strengthening_20260606/), Spec: [./tracks/data_structure_strengthening_20260606/spec.md](./tracks/data_structure_strengthening_20260606/spec.md), Plan: [./tracks/data_structure_strengthening_20260606/plan.md](./tracks/data_structure_strengthening_20260606/plan.md) (to be authored by writing-plans skill)*
+
+*Goal: Improve AI-readability by naming 430 currently-anonymous `dict[str, Any]` / `list[dict[...]]` / `Tuple[...]` types. New `src/type_aliases.py` with 10 `TypeAlias` definitions (`Metadata`, `CommsLogEntry`, `CommsLog`, `HistoryMessage`, `History`, `FileItem`, `FileItems`, `ToolDefinition`, `ToolCall`, `CommsLogCallback`) and 1 `NamedTuple` (`FileItemsDiff`). Mechanical replacement of 345 weak sites across 6 high-traffic files: `src/ai_client.py` (139), `src/app_controller.py` (86), `src/models.py` (51), `src/api_hook_client.py` (32), `src/project_manager.py` (20), `src/aggregate.py` (17). Add `--strict` mode to the existing `scripts/audit_weak_types.py` (committed in 84fd9ac9; found the 430 sites) so it becomes a permanent CI gate that fails when new weak types are introduced. Generate `scripts/audit_weak_types.baseline.json` with the post-refactor count. 2 phases: aliases + 6-file replacement + audit baseline; NamedTuples + docs + archive. **Data-grounded**: the audit script is the source of truth; the count drops from 430 to ~60 (86% reduction) in the 6 high-traffic files. **Honest about what's missing**: 23 lower-impact files remain; TypedDict/dataclass migration is deferred to a follow-up track. 2-3 days work, 1-2 phases, low risk. **Now blocked by** test_infrastructure_hardening_20260609 (was: none).*
+
+#### Track: MCP Architecture Refactor (Sub-MCP Extraction) `[track-created: 2720a894]`
+*Link: [./tracks/mcp_architecture_refactor_20260606/](./tracks/mcp_architecture_refactor_20260606/), Spec: [./tracks/mcp_architecture_refactor_20260606/spec.md](./tracks/mcp_architecture_refactor_20260606/spec.md), Plan: [./tracks/mcp_architecture_refactor_20260606/plan.md](./tracks/mcp_architecture_refactor_20260606/plan.md) (to be authored by writing-plans skill)*
+
+*Goal: Split the 2,205-line monolithic `src/mcp_client.py` (45 module-level functions) into a slim controller + 6 native sub-MCPs + 1 external sub-MCP. Naming convention `mcp_<type>.py` for native MCPs: `mcp_file_io.py` (9 tools), `mcp_python.py` (14), `mcp_c.py` (5), `mcp_cpp.py` (5), `mcp_web.py` (2), `mcp_analysis.py` (2). The existing `ExternalMCPManager` is extracted to `mcp_external.py` (class name preserved). New `MCPController` class in `src/mcp_client.py` holds the 3-layer security model (extracted to `src/mcp_client_security.py`), the `ALL_SUB_MCPS` registration list, and the inverted-dict dispatch lookup. New `src/mcp_client_legacy.py` re-exports all 45+ old symbols for backward compat (the 4 existing test files + `src/app_controller.py:61` continue to work). Each sub-MCP's `invoke()` returns `Result[str, ErrorInfo]` (Fleury pattern). Path parameters use the `Metadata` family aliases. **Blocked by** test_infrastructure_hardening_20260609, `data_oriented_error_handling_20260606` (for `Result`/`ErrorInfo`), and `data_structure_strengthening_20260606` (for `Metadata` aliases). 7 phases: foundation (security + controller), move-to-legacy, extract File I/O, extract Python, extract C/C++/Web/Analysis, extract External, dispatch update + docs + archive. **Out of scope** (per user): a per-MCP DSL (APL/K/Cosy-inspired) for compact tool calls — deferred to `mcp_dsl_20260606` follow-up. JSON-only for now.*

+#### Track: RAG Phase 4 Stress Test Fix `[x] — fixed 16412ad5`
+*Status: 2026-06-06 — Surfaced during post-v2 verification. Resolved: real bug, NOT a test flake. Root cause: ChromaDB collection dimension mismatch across test runs. The persistent on-disk collection (`tests/artifacts/live_gui_workspace/.slop_cache/chroma_test_stress/`) was created by a previous run with Gemini embeddings (3072-dim); the current run uses local SentenceTransformers (384-dim). `index_file()` upserts silently corrupt the collection, then `search()` fails with `Collection expecting embedding with dimension of 3072, got 384` and the AI request never reaches 'done' status, timing out the 50*0.5s = 25s poll loop. Fix: `RAGEngine._init_vector_store` now calls `_validate_collection_dim` which inspects the first existing vector's dim, compares to the current provider's output, and recreates the collection on mismatch (with a stderr warning). Regression tests added: `test_rag_collection_dim_mismatch_recreates_collection` and `test_rag_collection_dim_match_preserves_collection` in `tests/test_rag_engine.py`. This also fixes a real user-facing bug: switching embedding providers in the GUI previously caused silent corruption. Commit 16412ad5.*
+
+#### Track: Prior Session Test Harden (20260605) `[superseded by live_gui_test_hardening_v2_20260605]`
+*Status: 2026-05-05 — Surfaced during live_gui_fragility_fixes_20260605 execution. `test_prior_session_no_pop_imbalance::test_no_extraneous_pop_when_prior_session_renders` is more under-mocked than expected. Completed as part of live_gui_test_hardening_v2_20260605: test refactored to call narrow render_prior_session_view (50+ mocks -> 20, runtime 5.79s -> 0.08s). Commit 26e0ced4.*

+*Goal: Promote the ASCII-sketch UX ideation workflow (`docs/reports/ascii_sketch_ux_workflow_20260608.md`, 340 lines) to a real track. Resolves 5 open questions (vocabulary preference, comparison policy, storage location, tooling, frequency), then executes the workflow on the first target: the per-entry rendering of the Discussion Hub at `src/gui_2.py:3770 render_discussion_entry`. The 23-op matrix A1-A7 in `docs/guide_discussions.md` is the source of truth; the SSDL digest (`docs/reports/computational_shapes_ssdl_digest_20260608.md`, 504 lines) informs the *internal refactoring* decisions. Complements the broader 20260302 track. 4 phases, 21 tasks, TDD-style for Phase 3. User-confirmed worth doing.*
+*Status: Active; Phase 1 (5 open questions to the user) is the current phase.*

+#### Track: Chunkification Optimization (NEW 2026-06-08, CONTINGENCY)

+*Goal: Contingency document only. Activates ONLY when a hard constraint surfaces that no existing Python package can solve AND the target is hot enough to justify the C11 build cost. Per user (verbatim): "only worth it if I reach a hard constraint that I cannot solve with an existing python package." The 2 cited candidates (markdown parsing into aggregate markdown, context snapshot processing) are NOT currently bottlenecks per `src/aggregate.py:380-454` (pure-Python string concat, zero third-party markdown deps in `pyproject.toml:6-27`) and `src/history.py:1-141` (bounded ~500KB at 100-snapshot capacity, debounced). First fix if they become bottlenecks: add `markdown-it-py` OR switch to `pickle`/`msgspec` — NOT C11. The shape when activated: subprocess-launch C11 binary with request/response blob wire format (NOT stateful C extension). The SSDL digest's Technique 5 "Assume-away (Xar)" in §2.2 + "Xar-style chunked arrays" recommendation in §5.2 pre-support this track.*
+*Status: Deferred. Promotes to active track when (if) the first hard constraint surfaces.*

+*Goal: Build `src/code_path_audit.py` — a static-analysis tool that audits the 3 major actions (AI message lifecycle, discussion save/load, GUI startup) for expensive operations, redundant calls, and pipelining candidates. Output: custom postfix `.dsl` data + markdown + Mermaid + prefix tree text under `docs/reports/code_path_audit/<date>/`. The follow-up `pipeline_pruning_20260607` consumes the `.dsl` files; the markdown + tree are for human review. MMA worker spawn is **cold per user**. **Timing (revised 2026-06-08):** the audit must run *after* the 4 foundational tracks ship (`qwen_llama_grok`, `data_oriented_error_handling`, `data_structure_strengthening`, `mcp_architecture_refactor`); pre-4-tracks code is too stale to ground optimization decisions.*

+*Plan to be authored when data_oriented_error_handling_20260606 is complete; not started yet.*
+*Goal: Remove the deprecated `ai_client.send()` and migrate all callers to `send_result()`. Affects `src/app_controller.py:290` and `:3559`, `src/multi_agent_conductor.py:591`, `src/orchestrator_pm.py:86`, `src/conductor_tech_lead.py:68` (4 production call sites in `src/`), and ~50+ test files.

+   *Goal: Remove 30 confirmed-unused one-off scripts from `scripts/` (56 → 26 files, 54% reduction). 5 atomic per-category commits; no new CI gate; follow-up `unused_scripts_audit_20260607` recorded. All non-GUI test batches still pass; 2 audit scripts (main_thread_imports, weak_types) report no new violations.*

+   *Goal: Build `scripts/audit_license_cve.py` — single audit script that checks third-party deps (pyproject.toml + uv.lock transitive) for license compliance + known CVEs + version-pinning + SPDX source-headers. Tilde-pin all deps, delete requirements.txt, regenerate uv.lock (gitignored per project policy), add --strict mode + baseline file (CI gate). Policy: ALLOW (permissive + weak copyleft + public domain), BLOCK (GPL, AGPL, SSPL, BSL, Commons Clause, Elastic, unknown). Track is scope-limited to third-party deps; the project's own LICENSE and SPDX headers are explicitly OUT of scope (the user reserves all rights to the repo). 28 unit + integration tests passing; --strict mode wired as CI gate; baseline file committed at scripts/audit_license_cve.baseline.json. 4 atomic commits: audit script + initial report, tilde-pin + lock regen + delete requirements.txt, --strict + baseline, tracks.md update.*

+## Notes
+
+**Archive link convention:** `./archive/...` paths in this file resolve to `conductor/archive/...` (this file is at `conductor/tracks.md`). The 71 archive links in this file are all valid as of 2026-06-08.
+
+**Status legend:**
+- `[ ]` not started
+- `[~]` in progress
+- `[x]` completed (track may still be in `tracks/` or may have been moved to `archive/`)
+- `~~**...**~~` struck-through (renamed/replaced/superseded)
+
+**Naming convention:** Each track's `spec.md` and `plan.md` (where present) follow the project's standard format: `spec.md` for design intent (the "why"), `plan.md` for executable tasks (the "how"). See `conductor/tracks/data_oriented_error_handling_20260606/` for the canonical example.
+
+**Editing this file:** When you mark a track as `[x]` and move its folder to `archive/`, also move it to the appropriate Archived sub-section. When you start a new track, create the folder under `tracks/` first, then add the entry to the Active Tracks table at the top. The git-blame sort order (`0a`, `0b`, `0c`...) is no longer used; this file is now organized by phase + dependency.

+# Track Closeout Report: test_batching_refactor_20260606
+
+**Status:** SHIPPED 2026-06-08
+**Final state:** 4/4 phases complete (1 phase skipped with documented rationale)
+**Adapted from plan:** yes (3 deviations, all documented)
+
+---
+
+## What Shipped
+
+### New library modules (in `tests/`)
+- `tests/categorizer.py` — `CategoryRecord` + `FixtureClass` + `Speed` enums, AST-based auto-inference, TOML registry merge. **NO regex** (per user "FUCK REGEX" policy + prereq spec).
+- `tests/batcher.py` — `Batch` dataclass + `plan(records, options) → list[Batch]`. 6-tier isolation: opt-in / unit / mock_app / live_gui / headless / performance.
+- `tests/pytest_collection_order.py` — Conftest-loaded pytest plugin. Opt-in per-test order from registry; no-op when no entries.
+
+### Test files
+- `tests/test_categorizer.py` — 13 tests, all passing.
+- `tests/test_batcher.py` — 5 tests, all passing.
+- `tests/test_pytest_collection_order.py` — 2 tests, all passing.
+- `tests/test_categories.toml` — 5 hand-curated cross-cutting entries (arch_boundary_phase1/2/3, tier4_interceptor, tier4_patch_generation). Empty otherwise.
+
+### CLI orchestrator (in `scripts/`)
+- `scripts/run_tests_batched.py` — Replaces the alphabetical 4-at-a-time batcher. Features:
+  - `sys.path.insert` from script-relative `_PROJECT_ROOT` so paths resolve regardless of cwd
+  - `_HAS_XDIST` import-time detection; falls back gracefully when xdist missing
+  - `--tiers`, `--include-opt-in`, `--no-xdist`, `--plan`, `--audit`, `--strict`, `--durations`, `--no-color`
+  - Live output streaming via `subprocess.Popen` (no buffer)
+  - ANSI color (cyan `>>>`/`<<<`, green PASS, red FAIL) with Windows VT enable
+  - Output filter (LogPruner noise, WinError spam, xdist scheduling queue)
+  - Per-line colorization for both xdist (`[gwN] ... STATUS tests/...`) and non-xdist (`tests/... STATUS [P%]`) formats
+  - **Defensive failure detection**: scans captured output for `FAILED ` / `stopping after ` markers because `proc.returncode` is sometimes 0 even with a real test failure (commit `488ae044`)
+  - Dynamic-width SUMMARY table with TOTAL row (computed from actual data, not hardcoded)
+
+### Conftest integration
+- `tests/conftest.py:25` — Added `pytest_plugins = ["pytest_collection_order"]` (1 line; rest of conftest untouched)
+
+### Docs
+- `docs/guide_testing.md` — Added "Batched Run (Categorized)" subsection in Running Tests.
+
+### Cleanup
+- Old `scripts/run_tests_batched.py.legacy` deleted (commit `50f26f0d`)
+- `tests/.test_durations.json` added to `.gitignore` (commit `ac7e638b`)
+
+### Track artifacts
+- Archived to `conductor/tracks/archive_completed_tracks_20260603/test_batching_refactor_20260606/`
+- `conductor/tracks.md` updated to mark entry as `[x]` completed with phase SHAs

+
+## Adaptations from Plan
+
+| Plan | Actual | Why |
+|------|--------|-----|
+| Library in `scripts/` | Library in `tests/` | User directive ("put the test categorizer in ./tests, stop putting shit in scripts") |
+| `import re` for live_gui detection | AST scan via `ast.parse` + `ast.walk` | User "FUCK REGEX" policy + prereq spec §7 + AGENTS.md ban on `re` in production scripts |
+| Phase 2 = CI shadow run workflow | Phase 2 = manual plan-vs-actual spot-check | No CI infrastructure exists in repo |
+| Hardcoded column widths (38/10/6/8) | Dynamic widths computed from data | User feedback: "are you hardcoding the width?" |
+| `proc.returncode` for batch status | Output scan fallback for `FAILED ` / `stopping after ` | `proc.returncode` is 0 even on real failures (e.g. tier-3) — added defensive check |
+| `subprocess.run(capture_output=True)` (buffered) | `subprocess.Popen` + line streaming | User: "I don't see a live gui when the tests are running? nvm I do" — needed per-test visibility |
+| Filter all noise (including scheduling, test paths) | Filter only LogPruner/WinError/xdist queue | User: "HOw tf did we get to this point where now we just want to omit info?" |
+
+---
+
+## Verification Criteria (from metadata.json)
+
+| Criterion | Status | Evidence |

+| 20/20 new tests pass | ✓ | All three test files: 20 passed in <0.3s |
+| `categorize_all` returns 277+ records | ✓ | Returns 301 records on the actual repo (no exceptions) |
+| All 14 `*_sim.py` in ONE tier-3 batch | ✓ | `pytest_collection_order` + AST scan finds 48 live_gui users (broader than just `*_sim.py`), all in tier-3-live_gui single batch |
+| Opt-in tests skip silently without env var | ✓ | `--include-opt-in not set` shown for `tier-0-opt_in-clean_install` and `tier-0-opt_in-docker_build` |
+| `--audit --strict` exits 0 | ✓ | No cross-cutting auto-classified files (zero STRICT violations) |
+| `pytest_collection_order` is no-op when no `[[test_order]]` entries | ✓ | Test `test_no_op_without_registry` passes |
+| >80% coverage on new code | Partial | Tests are coarse-grained (small target surface). Not measured explicitly; the functions are short and tested. |

+
+## Known Follow-up Issues (out of scope for this track)
+
+### 1. `test_full_live_workflow::test_full_live_workflow` FAILED
+- **Tier-3 batch correctly reports FAIL** (commits `5c6eb620`, `488ae044`)
+- Failure: `AssertionError: Project failed to activate` after 10-iteration poll on `client.get_project()` for new project name
+- Test does: `client.click("btn_project_new_automated", user_data=temp_project_path)` then polls for `'temp_project'` to appear in `client.get_project()` response
+- **Likely root causes to investigate (separate track):**
+  - Button ID `btn_project_new_automated` may have been renamed/removed
+  - Project activation callback not firing within the 10s window
+  - Test artifact `temp_project.toml` path issue (the test does `os.path.abspath("tests/artifacts/temp_project.toml")` from cwd — depends on cwd)
+  - `_default_windows` mismatch (recent multi-theme refactor changed defaults)
+- The test was previously failing per `tracks.md` line 162 ("Pre-existing test failures (unrelated)"): `test_api_generate_blocked_while_stale` (ui_global_preset_name AttributeError) and `test_rag_large_codebase_verification_sim` (RAG retrieval)
+- **Now passes**: `test_api_generate_blocked_while_stale` PASSED in 0.62s when run in isolation (was a flake, now fixed by the recent `_default_windows` changes)
+- **Newly surfaced**: `test_full_live_workflow` is now the remaining known failure
+
+### 2. `PytestUnknownMarkWarning: Unknown pytest.mark.live`
+- Tests use `@pytest.mark.live` (test_visual_mma.py:5, test_visual_sim_gui_ux.py:7,59)
+- pyproject.toml `[tool.pytest.ini_options] markers` does not register `live`
+- Warnings emitted every tier-3 run
+- Fix: add `"live: marks tests as live visualization tests"` to `pyproject.toml` markers list
+
+### 3. `LogPruner` race on Windows
+- Logs `Error removing ... : [WinError 32] The process cannot access the file because it is being used by another process: 'apihooks.log'`
+- Tests launch live_gui fixture which writes to `apihooks.log`; LogPruner tries to delete old session directories while the new test is still using the log
+- Mostly cosmetic but pollutes output
+- Root cause: LogPruner and live_gui teardown don't coordinate file locks
+- **Batcher filters these lines from output** (commits `5c6eb620`); the actual race is a separate concern
+
+### 4. Conftest.py indentation drift
+- `tests/conftest.py` uses 4-space indentation throughout (out of project standard 1-space)
+- Out of scope for this track; refactoring would require touching 545+ lines
+- Documented in `conductor/edit_workflow.md` as a known issue
+
+### 5. State file format drift
+- `state.toml` has duplicate `[meta] status` lines (an earlier `set_file_slice` inserted without removing the original)
+- Phase task descriptions reference the OLD `scripts/` location for the library (plan was written before user moved it to `tests/`)
+- Tracked here; state file is archived, won't be auto-parsed by future agents
+
+### 6. User's TOML files commit pollution
+- Throughout the track, `config.toml`, `project.toml`, `project_history.toml`, and `manualslop_layout.ini` got pulled into commits because they had unstaged changes that were inadvertently included by `git add`/`git add -A` calls
+- The user said "I'm too tired to correct this shit" — explicit acknowledgement, not fixed
+- Future agents should `git status` before each commit and explicitly add only the relevant files
+
+### 7. Tier 1 + Tier 2 not all runnable in <120s
+- Full tier-1 (216 unit tests) takes ~89s
+- Full tier-2 (31 mock_app tests) takes ~28s
+- Full tier-3 (48 live_gui tests) takes ~178s
+- Total: ~295s for default `--tiers 1,2,3,H`
+- Per `conductor/workflow.md` TDD protocol, this exceeds the 120s tool timeout — but the runner buffers output correctly so partial results are visible; the final SUMMARY is what matters
+- Acceptable for a developer-ergonomics tool, not a blocker
+
+---
+
+## Follow-up Track Recommendation
+
+`fix_live_workflow_test_20260608` (or similar):
+- **Owner:** Tier 2 Tech Lead
+- **Priority:** Medium (one known failure; doesn't block other tracks)
+- **Scope:** Root-cause `test_full_live_workflow` project activation timeout; fix or quarantine with skipif
+- **Also include:** Add `live` to pytest markers; coordinate LogPruner + live_gui teardown
+- **Blocked by:** None
+- **Estimated phases:** 1-2 phases (investigation + fix-or-skip)

+# Track: Chunkification Optimization (C11 Pipeline Contingency)
+
+**Status:** Placeholder / contingency (do not start without a hard constraint)
+**Initialized:** 2026-06-08
+**Owner:** Tier 2 Tech Lead
+**Priority:** DEFERRED (no current bottleneck)
+
+> **The one-paragraph summary.** This is a *contingency document*, not an active track. It activates only when a hard constraint surfaces that no existing Python package can solve, AND the target is hot enough that the C11 build cost is justified. Per user (verbatim): *"only worth it if I reach a hard constraint that I cannot solve with an existing python package. Then I could make a custom pipelien to deal with the hot data set witha custom cpython extension."* The 2 cited candidates (markdown parsing into aggregate markdown, context snapshot processing) are **not currently bottlenecks** per `src/aggregate.py:380-454` (current implementation is pure-Python string concat, zero third-party markdown deps in `pyproject.toml:6-27`) and `src/history.py:1-141` (snapshot deep copy is bounded ~500KB at 100-snapshot capacity, debounced in `gui_2.py:1140-1170`).
+>
+> **The activation plan** is the substantive content of this doc — what to build *if/when* the hard constraint surfaces. The shape is a request-blob → C11 pipeline → response-blob subprocess, NOT a stateful CPython C extension. This is the v2 framing from `docs/reports/c11_python_interop_assessment_20260608.md` Part 3, §3.5-3.12.
+
+---
+
+## 1. Why this is a contingency, not a track
+
+### 1.1 The two target use cases are not currently bottlenecks
+
+**Markdown parsing into aggregate markdown:**
+- `src/aggregate.py:380-454` (`build_markdown_from_items`) builds markdown by **pure-Python string concatenation** (`f"### \`{original}\`\n\n\`\`\`{suffix}\n{skeleton}\n\`\`\""` and `"\n\n---\n\n".join(sections)`)
+- `pyproject.toml:6-27` has **zero third-party markdown dependencies** (`mistune`, `markdown-it-py`, `commonmark-py`, `markdown` are all NOT in deps)
+- `src/summarize.py:7-219` `_summarise_markdown` only extracts headings; doesn't parse body
+- **First fix if this becomes a bottleneck:** add `markdown-it-py` to `pyproject.toml`. ~1 line change, ~10x speedup over pure-Python regex parsing. NOT C11.
+
+**Context snapshot processing:**
+- `src/history.py:1-141` `UISnapshot` is a 13-field dataclass. 100-snapshot default capacity. ~500KB max payload
+- `HistoryManager` snapshot capture is debounced at render frame (`gui_2.py:1140-1170`), not per-frame
+- `to_dict()` / `from_dict()` deep-copies are the only meaningful work
+- **First fix if this becomes a bottleneck:** switch from `to_dict`/`from_dict` to `pickle` (5-10x faster) or `msgspec` (10-20x faster). NOT C11.
+
+### 1.2 The threshold is "hard constraint that no existing Python package can solve"
+
+Per user, the C11 path is justified ONLY when profiling demonstrates a real bottleneck AND the existing-Python-package fix has been tried and doesn't work. **This has not happened yet.**
+
+---
+
+## 2. The activation plan (what to build when the constraint surfaces)
+
+### 2.1 Wire format (the contract)
+
+The Python side builds a request envelope; the C11 side reads it, runs ops, writes a response. The wire format is the ONLY contract; both sides agree on it.
+
+**v1 (text, debuggable):**
+```
+# request.txt
+op parse_md
+op summarise_python
+op mask_symbols @sym1 def @sym2 sig
+op build_section tier=3
+input file src/foo.py
+input file src/bar.py
+format markdown_v3
+end
+```
+
+**v2 (binary, fast):**
+```
+[1 byte: format version]
+[1 byte: op_count]
+[for each op: op_id | param_count | params]
+[for each input: byte_len | path | content]
+```
+
+**Recommended:** start with text v1, switch to binary v2 if profiling shows parse cost matters. A reasonable middle path: **text envelope + binary payloads** (you can `cat` the envelope to debug; the heavy bytes move binary).
+
+### 2.2 The C11 pipeline API
+
+Single entry point. Standalone binary. No Python awareness.
+
+```c
+// chunks_module.c (hypothetical)
+typedef Struct_(PipelineResponse) {
+    U8* bytes;
+    U8  len;
+    U4  exit_code;   // 0 = success
+    Str8 error_msg;  // optional
+};
+
+IA_ PipelineResponse pipeline_run(Slice request);
+```
+
+The C side:
+1. Parses the request envelope
+2. Loads input files (or accepts inline blobs)
+3. Runs each op in order
+4. Collects output into response blob
+5. Returns exit code + response
+
+### 2.3 The Python wrapper
+
+```python
+# Python side (hypothetical)
+import subprocess
+import json
+
+def run_pipeline(request: str) -> str:
+    """Shell out to the C pipeline; return parsed response."""
+    proc = subprocess.run(
+        ["./manual_slop_pipeline"],  # the C binary
+        input=request,
+        capture_output=True,
+        text=True,
+        timeout=30,
+    )
+    if proc.returncode != 0:
+        raise PipelineError(proc.stderr)
+    return proc.stdout
+```
+
+**Subprocess model is recommended for v1:**
+- Zero FFI surface (no ctypes, no PyTypeObject, no refcount discipline)
+- Trivially testable from the shell
+- Total process isolation (C crash doesn't take down Python)
+- ~10-20ms startup tax per call (acceptable for batch ops, not for per-frame hot loops)
+- Easy to swap implementations (rewrite the binary, keep wire format)
+
+**Move to in-process FFI only if subprocess startup is the new bottleneck.** The wire format doesn't change.
+
+### 2.4 The chunkification (Reece's Xar pattern in duffle.h style)
+
+The chunk-array lives *inside* the C pipeline as a private implementation detail. Python never sees it.
+
+```c
+// chunks_module.c (hypothetical, duffle.h style)
+typedef Struct_(ChunkArray) {
+    Slice  chunks;        // { Chunk* ptr; U8 len; }
+    U4     chunk_size;    // power-of-2
+    U4     element_size;
+    U8     total_used;
+    FArena backing_arena;
+};
+
+IA_ U8 chunka_push(ChunkArray* ca, U8 element) {
+    U4 chunk_idx = ca->total_used >> log2_of(ca->chunk_size);
+    if (chunk_idx >= ca->chunks.len) {
+        Chunk* new_chunk = farena_push_type(& ca->backing_arena, Chunk, .alignment=64);
+        ca->chunks.ptr[ca->chunks.len] = new_chunk;
+        ca->chunks.len += 1;
+    }
+    U4 offset = ca->total_used & (ca->chunk_size - 1);
+    U8* dst = (U8*)&ca->chunks.ptr[chunk_idx][offset * ca->element_size];
+    dst[0] = element;
+    ca->total_used += 1;
+    return ca->total_used - 1;
+}
+
+IA_ U8 chunka_at(ChunkArray* ca, U8 i) {
+    U4 chunk_idx = i >> log2_of(ca->chunk_size);
+    U4 offset    = i & (ca->chunk_size - 1);
+    return ((U8*)ca->chunks.ptr[chunk_idx])[offset * ca->element_size];
+}
+```
+
+This is Reece's Xar pattern (8-byte header, power-of-2 chunks, bitwise divmod) written in the user's duffle.h style. ~200 lines of C for the chunk-array + ops.
+
+### 2.5 Build + deploy
+
+- **Build:** `clang -O3 -std=c23 -shared chunks_module.c -o libchunks.so` (or .dll on Windows)
+- **Distribution:** ship the binary alongside the Python wheel. uv + pyproject.toml can reference a `[tool.uv.scripts]` entry that builds the C binary as part of `uv sync`
+- **Test:** `tests/test_chunka_c11.py` — TDD-style, write Python tests first, then write the C, verify
+- **Subprocess invocation:** `subprocess.run([sysconfig.get_path("scripts") + "/manual_slop_pipeline"], ...)`
+
+### 2.6 The decision tree (when activated)
+
+```
+Is the target code path actually a bottleneck in profiling?
+├── No  → Don't activate. Re-evaluate next quarter.
+│
+└── Yes → Is the bottleneck solvable with existing Python packages?
+    ├── Yes (e.g., switch to_dict/from_dict to pickle) → Apply that fix.
+    │         Cost: hours. Don't reach for C11.
+    │
+    └── No (existing packages aren't fast enough) → Activate this track:
+              1. Define wire format (text v1, binary v2)
+              2. Write C11 pipeline binary in duffle.h style
+              3. Write Python wrapper (subprocess.run)
+              4. Profile: confirm C11 path is faster than Python baseline
+              5. If not faster, throw away C11 code and try different Python package
+```
+
+---
+
+## 3. Activation criteria (the 4 questions to revisit)
+
+These are the design decisions to make *when* (not before) the user hits a real bottleneck:
+
+1. **Which target?** Is it markdown parsing, snapshot processing, log aggregation, RAG indexing, or something else? Each has different op shapes.
+2. **Subprocess or in-process FFI?** Start with subprocess. Move to in-process only if startup cost is the new bottleneck.
+3. **Text or binary wire format?** Text v1 (debuggable). Binary v2 (fast). Envelope-text + payload-binary middle ground.
+4. **One pipeline binary or many?** One binary with op registry (simpler to build/test/deploy). Many binaries (more modular, harder to coordinate). Recommend one binary.
+
+---
+
+## 4. What this track does NOT produce (today)
+
+- No C code
+- No Python wrapper
+- No build configuration
+- No tests
+- No profiling
+- No activation
+
+This track produces only this contingency document. It is **not** in the active queue. It does not appear in `conductor/tracks.md` "Active Tracks" table. It appears in the "Future / Contingency" section as a *reference*, not a *commitment*.
+
+---
+
+## 5. What this track IS
+
+- A clear, pre-defined activation plan so when a hard constraint surfaces, the implementation work is already scoped
+- An honest record that the current bottlenecks are not yet hard constraints
+- A reference for the user's "what would C11 interop look like?" question, answered with the request/response pipeline model
+- A reminder that "default action is don't" — the existing Python tooling should be tried first
+
+---

+- `docs/reports/computational_shapes_ssdl_digest_20260608.md` — the **SSDL digest** (the theoretical foundation for this track; see §5.2 "Xar-style chunked arrays" + Technique 5 "Assume-away (Xar)" in §2.2 for the explicit pre-supports of this pattern; "Assume as much as possible" lens in §4 is the threshold-shift rationale — if the cost of being wrong is low, assume; if high, use a different structure)

+- `src/history.py:1-141` — the current snapshot hot path (NOT a bottleneck today)
+- `pyproject.toml:6-27` — current zero-markdown-deps state
+
+### 6.1 The SSDL alignment (why the chunkification is the *correct* shape, when activated)
+
+The SSDL digest's §2.2 enumerates 5 defusing techniques. The chunkification pattern is Technique 5 ("Assume-away (Xar)"). The digest's §5.2 explicitly recommends "Replace `realloc`-style growable buffers with Xar-like chunked arrays for chat history, log buffers, and the comms log" — which is *exactly* this track's target.
+
+The §5.1 "low-cost, high-value" recommendations include the "Add generational handles to the `TrackDAG` and `Ticket` system" pattern. If the chunkification track activates for `comms.log`, the *adjacent* ticket-storage refactor (per the digest's §5.2 "Refactor MMA ticket storage toward an ECS shape") becomes a natural follow-up.
+
+**The SSDL digest pre-supports this track.** When the activation criteria are met, the theoretical foundation is already in place. The implementation work is *applying* the SSDL's Technique 5 + the user's duffle.h style to a specific target.
+
+---
+
+*End of contingency. Status: DEFERRED. Promote to active track when (if) the first hard constraint surfaces.*

+# Track: Code Path & Data Pipeline Audit
+
+**Status:** Spec approved 2026-06-07; revised 2026-06-08 with post-4-tracks timing and 5-source framing
+**Initialized:** 2026-06-07
+**Owner:** Tier 2 Tech Lead
+**Priority:** Medium (foundational; enables follow-up pruning track)
+
+> **Revision note (2026-06-08).** The user specified that this audit should run *after* the 4 foundational tracks complete (`qwen_llama_grok_integration_20260606`, `data_oriented_error_handling_20260606`, `data_structure_strengthening_20260606`, `mcp_architecture_refactor_20260606`). The 4 tracks will significantly reshape `src/ai_client.py`, `src/mcp_client.py`, `src/app_controller.py`, and `src/type_aliases.py` — running the audit on the pre-refactor code would produce a report that's stale on day 1. The post-4-tracks timing ensures the audit grounds optimization decisions for the *resulting* architecture, not the pre-refactor one. See §"Timing" below.
+
+---
+
+## Overview
+
+Build `src/code_path_audit.py` — a data-oriented static-analysis tool that audits the 3 major actions (AI message lifecycle, discussion save/load, GUI startup) for expensive operations, redundant calls, and pipelining candidates. The output (custom postfix `.dsl` data + markdown + Mermaid + prefix tree text) is the artifact that informs pipeline-pruning decisions; the actual code changes are a follow-up track (`pipeline_pruning_20260607`).
+
+Per the user's framing: "anything that can even remotely smell as an expensive bulk action or major action that takes more than 10-40 microseconds." The audit focuses on **expensive** operations (file I/O, network, AST parsing, big loops, anything that smells like a bulk action) inside the 3 actions — not on every state mutation. The cost model is heuristic, calibrated by a runtime-profiling follow-up (`pipeline_runtime_profiling_20260607`) that catches the cases static analysis can't resolve (C-extension cost, import cost, JIT effects, decorator-driven dispatch).
+
+The MMA worker spawn action is **out of scope** for this track (per user: "keeping that cold for a while until I like the main ux loop with ai in a discussion fully dogfooded").
+
+## Timing (post-4-tracks)
+
+This track is intentionally **deferred** until *after* the 4 foundational tracks ship:
+
+1. `qwen_llama_grok_integration_20260606` — adds 3 vendors (`_send_qwen`, `_send_llama`, `_send_grok`) and refactors `_send_minimax` to use the shared `send_openai_compatible()` helper. Modifies `src/ai_client.py`, `src/openai_compatible.py` (new), `src/vendor_capabilities.py` (new).
+2. `data_oriented_error_handling_20260606` — refactors `ai_client._send_<vendor>` to return `Result[str]`, modifies `mcp_client.py` (30+ sites), `rag_engine.py` (Result returns).
+3. `data_structure_strengthening_20260606` — adds `src/type_aliases.py` with 10 TypeAliases, replaces 345 weak-type sites across 6 files.
+4. `mcp_architecture_refactor_20260606` — splits `src/mcp_client.py` (2,205 lines → 6 sub-MCPs + 1 external), adds `src/mcp_client_legacy.py` for backward compat.
+
+Running the audit on the **pre-refactor** `src/` would produce a report that's stale on day 1. The post-4-tracks timing ensures:
+- The audit's data grounds optimization decisions for the *resulting* architecture (post-Fleury-style "effective codepaths" and "ECS archetype tables" if the 4 tracks are implemented with the data-oriented philosophy).
+- The `pipeline_pruning_20260607` follow-up has the *right* candidates to optimize — the 4 tracks will move the expensive ops around, and pruning the wrong ones wastes work.
+- The runtime-profiling follow-up (`pipeline_runtime_profiling_20260607`) measures the *new* code paths, not the old ones.
+
+**Pre-flight check (verifies the 4-tracks baseline before this track starts):** confirm that all 4 tracks are marked `[x]` completed in `conductor/tracks.md`. If any of the 4 are still `[~]` in-progress, this track is blocked — the audit would catch the in-progress state as drift.
+
+## Analytical Framing (5-source lens)
+
+The 5 sources loaded into context for the post-4-tracks audit collectively reframe *what* to look for in the 3 actions. The audit's static cost model and pipeline-pruning recommendations should be informed by:
+
+| Source | Lens the audit inherits |
+|---|---|
+| [Ryan Fleury, "A Taxonomy of Computation Shapes"](https://www.dgtlgrove.com/p/a-taxonomy-of-computation-shapes) (Feb 2023) | The 6 shapes: instruction, codepath, wide codepath, codecycle, wide codecycle, codecycle graph. The audit's `trace_action` is a codepath visualization; the `redundancy` (call_count > 1) field detects **wide codepaths** that could be split into parallel sub-codepaths. |
+| [Ryan Fleury, "The Codepath Combinatoric Explosion"](https://www.dgtlgrove.com/p/the-codepath-combinatoric-explosion) (Apr 2023) | The "effective codepath" concept. The audit's `pipelining_candidates` field detects codepaths that *could be defused* (multiple real codepaths collapsed into 1 effective codepath via nil sentinels, generational handles, or immediate-mode APIs). The `redundancy` field is the *first indicator* of defusing opportunities. |
+| [Casey Muratori, "The Big OOPs: Anatomy of a Thirty-Five-Year Mistake" (BSC 2025)](https://youtu.be/wo84LFzx5nI) | The 35-year-historical indictment of compile-time domain hierarchies. The audit's per-function `state_mutations` index reveals whether a function is in the *system* pattern (mutates component-like data, not entity state) or the *entity-hierarchy* pattern (mutates a single object's identity, where the cost compounds per type). Functions in the latter pattern are the *highest-priority* refactor targets — they may need to be split into components + systems. |
+| [Andrew Reece, "Assuming as Much as Possible" (BSC 2025)](https://www.youtube.com/watch?v=i-h95QIGchY) | The "assume as much as possible" engineering discipline. The audit's `expensive_ops` index, for any function that calls a general-purpose primitive (e.g., `json.dumps`, `Path.read_text`, `ast.parse`), should ask: **"can this caller assume a smaller input domain and use a specialized primitive instead?"** A function that calls `json.dumps` 50 times per action with 1KB payloads each may be replaceable by a function that calls a domain-specific serializer once with a 50KB payload. |
+| User's chunk-ideation archive (May 2026) | The "fixed-size slices" + "ECS archetype tables" pattern. The audit's per-function calls that operate on lists/arrays should be flagged if they: (a) don't have a chunk-aware variant, (b) are in a hot path, (c) the data shape is uniform enough to chunk. Functions that match all 3 are the **prime candidates** for `pipeline_pruning_20260607` — chunkification is a known pattern with bounded risk. |
+
+**Concrete audit-time heuristics** that emerge from this framing:
+
+- **Effective-codepath count:** when a function has 3+ branches that all do roughly the same thing with different inputs, the audit should report "this is N real codepaths behaving as 1 effective codepath — could be defused with a nil sentinel or generational handle." The runtime-profiling follow-up measures the actual savings.
+- **Entity-hierarchy fingerprint:** when a function's `state_mutations` list has > 3 writes to a single `self.X` with a `type` discriminator, the audit should report "this function is operating on entity-hierarchy state; consider ECS split into components + systems." A *concrete Manual Slop example* the audit should catch: any function that does `if self.active_ticket.kind == TicketKind.X:` and then mutates multiple fields.
+- **Assumed-too-much detector:** when a function calls `ast.parse` (or any `tree_sitter.*`) on a file that *could be assumed* to be already-parsed (because the file is in the context composition and the `aggregate.py` pipeline has already done it), the audit should report "this is re-parsing data that was already parsed upstream; consider memoizing or threading the parsed AST through." This is the "assume as much as possible" pattern at the data-passing level.
+- **Chunkification candidates:** when a function loops over a `list[dict]` with a known uniform shape (heuristic: all dicts have the same key set), the audit should report "consider chunkifying — uniform data, hot path, no chunk awareness." The user has explicit code (`docs/ideation/ed_chunk_data_structures_20260523.md`) for the chunk pattern, so the audit's optimization candidates can cite it.
+
+These heuristics are *guidance for the audit's report interpretation* — they don't change the audit's static cost model (which is data-grounded in the existing `EXENSIVE_THRESHOLD` + per-class weights). They shape how the Tier 2 Tech Lead and the user interpret the report.
+
+## Current State Audit (as of `ca781543`)
+
+`src/` has 61 `.py` files (27,447 total lines; 23,845 code lines). The call graph is non-trivial; per-action traversal is what makes the analysis tractable.
+
+### Already Implemented (DO NOT re-implement; KEEP / build on)
+
+1. **`src/mcp_client.py:934-992` — `derive_code_path(target, max_depth=5)`.** A single-symbol recursive call tracer with text output. Doesn't render multi-action graphs, doesn't track mutations, doesn't measure cost. The new tool is the multi-action + mutation + cost version of this primitive. **Build on this:** lift the AST traversal logic and `trace()` recursion pattern into `code_path_audit.py`.
+2. **`scripts/audit_main_thread_imports.py`** — static CI gate for import-time purity. Different concern (startup-time import cost), but its AST-walking pattern is the model for `code_path_audit.py`'s implementation.
+3. **`src/performance_monitor.py`** — runtime profiling with `monitor.scope("name")` and per-component hit counts + latencies. Used at runtime; the follow-up `pipeline_runtime_profiling_20260607` track will use it to calibrate the heuristic cost model.
+4. **`conductor/archive/code_path_analysis_20260507/`** — prior manual audit + `PIPELINE_ANALYSIS.md` + Mermaid diagrams for the major pipelines. Manual effort, no reusable tool. New track is the data-grounded successor.
+5. **`conductor/archive/ai_interaction_call_graph_20260507/`** — sequence diagram for the AI loop. New track supersedes this for the 3 actions in scope.
+6. **SDM docstrings** (`[C: ...]` / `[M: ...]` tags in `src/*.py` docstrings) — pre-computed caller/mutation info. The new audit tool will be a more rigorous version of what SDM already documents ad-hoc.
+
+### Gaps to Fill (this track's scope)
+
+- A static call-graph builder for all of `src/` (multi-action, depth-configurable, machine-readable output).
+- A state-mutation index per function (5 mutation kinds: `attr_write`, `container_mutate`, `file_write`, `ipc_emit`, `global_write`).
+- An expensive-ops index (7 cost classes, with a heuristic data-size estimate).
+- A per-action traversal API (`trace_action(action, max_depth=10) -> ActionProfile`).
+- An output suite: custom postfix `.dsl` data files + markdown summaries + Mermaid per-action call graphs + prefix-tree text view.
+- A CLI (`python -m src.code_path_audit --action <name>`) and an MCP tool (`code_path_audit(action_name, max_depth)`).
+- The actual audit run on the 3 actions, with the report committed to `docs/reports/code_path_audit/2026-06-07/`.
+
+## Goals
+
+1. **Produce a queryable artifact.** The custom postfix `.dsl` output is the source of truth; markdown + Mermaid + prefix-tree text are for human review. Re-run after any `src/` change to see drift.
+2. **Surface the top-N optimization candidates per action.** The `summary.md` ranks candidates by potential data-transform load reduction. This is what the user will use to decide which pruning/optimization work to do next.
+3. **Data-grounded design.** The audit's data structure is the spec; the heuristics and the threshold are module-level constants tunable from one place.
+4. **Reusable across actions.** The `trace_action` API takes any `Action` (entry point + description). Adding a 4th action (e.g., MMA worker spawn, when it's no longer cold) is one `Action(...)` declaration.
+5. **Surface calibration gaps clearly.** When the static heuristic can't resolve a call (C-extension, decorator-driven dispatch, `getattr` magic), the report flags it as "unresolved" so the runtime-profiling follow-up targets it.
+
+## Non-Goals
+
+- Not implementing the actual code optimizations — that's `pipeline_pruning_20260607`.
+- Not profiling runtime costs — that's `pipeline_runtime_profiling_20260607`.
+- Not analyzing the MMA worker spawn action (cold per user).
+- Not analyzing `simulation/*` or `tests/*` directories.
+- Not analyzing actions beyond the 3 in scope.
+- Not resolving C-extension call costs statically.
+- Not resolving decorator-driven call dispatch statically (e.g., `@property`, `@imscope`).
+- Not providing real microsecond measurements — the cost is heuristic (calibrated later).
+
+## Architecture
+
+`src/code_path_audit.py` — single new module, no new dependencies. Exposes both an MCP tool surface (for agents) and a CLI (`python -m src.code_path_audit ...`).

+
+### Cost Model (heuristic, calibrated by the runtime-profiling follow-up)
+
+| Pattern | Cost class | Default weight | Data size source |
+|---------|-----------|----------------|------------------|
+| `open()`, `Path.read_*`, `Path.write_*`, `*.write_text` | `file_io` | 100 | file size from `Path.stat()` when resolvable, else `None` |
+| `requests.*`, `urllib.*`, `websockets.*`, `client.send` (with httpx-like signatures) | `network` | 500 | payload size from param literal/typed hint |
+| `ast.parse`, `ast.walk`, `tree_sitter.*` | `ast_parse` | 200 | source bytes from the path arg |
+| `json.dump`, `json.load`, `tomli_w.dump`, `tomllib.load` | `json_io` | 150 | container length if param is a list/dict |
+| `pickle.dump`, `pickle.load` | `pickle` | 300 | container length |
+| `copy.deepcopy` | `deep_copy` | 200 | container length |
+| Any call inside the body of a `for` / `while` loop | `loop_amplified` | caller_weight × loop_bound_estimate | loop bound = `range(...)` literal/arg, else 1 |
+
+**Expense threshold:** `EXPENSIVE_THRESHOLD = 40_000` (module-level constant). Any `ExpensiveOp.weight > EXPENSIVE_THRESHOLD` is flagged "expensive" in the per-action report. The 40,000 default matches the user's stated 10-40μs range; the runtime-profiling follow-up will calibrate it.
+
+**Unresolved calls:** when the AST walker cannot resolve a callee (e.g., attribute access on `self.X` where `X` is set dynamically; `getattr`; decorator-wrapped method dispatch), the call goes into `unresolved_calls` with a `"unresolved"` cost class and weight 0. The report's caveats section notes these; the runtime-profiling follow-up measures them.
+
+### Out of the static analysis
+
+- C-extension call costs (imgui-bundle, tree-sitter native) — runtime profiling only.
+- Decorator-driven dispatch (e.g., `@property`, `@imscope`) — runtime profiling only.
+- Import cost at module load time — covered by the existing `scripts/audit_main_thread_imports.py`.
+- `eval` / `exec` calls — flagged as unresolved, not analyzed.
+
+## Per-Action Design
+
+For each of the 3 actions, the audit is invoked with one or more entry points and a depth limit (default 10). The audit produces an `ActionProfile` that the report renders.
+
+| Action | Entry points | Expected high-cost ops the audit should surface |
+|--------|--------------|------------------------------------------------|
+| **AI message lifecycle** | `src.app_controller.AppController.process_user_request`, `src.ai_client.AIClient.send`, `src.aggregate.build_file_items`, `src.summarize._summarise_*` | Per-context-file AST parse in `build_file_items`; AI network call; history append + comms log append + session_logger file write; sub-agent summarization (network + AST, loop-amplified over context files) |
+| **Discussion save/load** | `src.project_manager.save_project`, `src.project_manager.load_project`, `src.history.HistoryManager.save_snapshot`, `src.models.parse_history_entries` | `tomli_w.dump` / `tomllib.load` on project TOML; `json.dump` on comms log (loop-amplified per entry); history file read/write; AST parse on schema validation |
+| **GUI startup** | `sloppy.main` → `gui_2.App.__init__`, `src.app_controller.AppController.__init__`, `src.paths._resolve_*` | `tomllib.load` on config.toml; AST parses for tool registration; file stat on log paths; `sloppy.py` first-frame import chain (covered by the existing `scripts/audit_main_thread_imports.py`) |
+
+The user can extend with more actions later (e.g., MMA worker spawn when it's no longer cold). Each action is one `Action(...)` declaration + a `trace_action()` call.
+
+## Output Format
+
+CLI:
+```bash
+uv run python -m src.code_path_audit --action ai_message_lifecycle [--depth N] [--dsl] [--tree] [--markdown] [--mermaid]
+```
+
+MCP tool (for agents):
+```python
+code_path_audit(action_name: str, max_depth: int = 10) -> dict
+```
+
+Generated artifacts (all under `docs/reports/code_path_audit/<YYYY-MM-DD>/`):
+
+| File | Format | Purpose |
+|------|--------|---------|
+| `call_graph.dsl` | Custom postfix DSL | Full call graph (all of `src/`); machine-readable, parses in ~30 lines |
+| `expensive_ops.dsl` | Custom postfix DSL | Expensive ops index (per-file, per-function) |
+| `state_mutations.dsl` | Custom postfix DSL | State mutations index (per function) |
+| `actions/<action>.dsl` | Custom postfix DSL | Per-action profile (machine-readable) |
+| `actions/<action>.tree` | Prefix tree (text) | Per-action human-readable tree (for human review) |
+| `actions/<action>.md` | Markdown | Per-action summary + table (for code review) |
+| `actions/<action>.mmd` | Mermaid | Per-action call graph (visual) |
+| `summary.md` | Markdown | Top-level cross-action summary + ranked optimization candidates |
+| `optimization_candidates.md` | Markdown | Ranked list with: candidate, current cost, proposed reduction, effort, priority |
+
+The two follow-up tracks consume the .dsl files; the markdown + tree are for human review.
+
+**The custom DSL is postfix (RPN) with length-prefixed lists** — no brackets, no braces, no commas, no colons. Each "word" is a tagged constructor that consumes a known number of args from the stack (e.g., `fn` consumes 3, `exp-op` consumes 5, `mut` consumes 3, `N list` consumes N items). Whitespace-tokenized. Strings are bare atoms when they have no whitespace; quoted only when needed. `nil` for null. `\` for line comments. The DSL is deliberately NOT strict Forth — it's a custom postfix format tailored to the audit's record shapes (function, call, mutation, expensive op, pair, list).
+
+Example of a single FunctionNode record:
+
+```text
+\ FunctionNode: fqname file line fn
+"src.ai_client.AIClient.send" "src/ai_client.py" 100 fn
+"build_file_items" call
+"process_response" call
+"self.history" attr_write 110 mut
+"open" file_io 100 120 exp-op
+```
+
+**The prefix tree renderer** is a separate human-readable view of the same data — top-down, `├─`/`└─`/`│` box-drawing, scannable. Generated by a recursive walker. Inlined in the markdown reports (optionally produced as `actions/<action>.tree` for tooling).
+
+**Why custom postfix DSL (not JSON, not s-expressions, not strict Forth):**
+- **Not JSON** (JSON is ill-performant: quoting, escaping, hash table allocation, no streaming).
+- **Not s-expressions** (the bracket version drifts back toward s-exprs; the user wanted postfix specifically).
+- **Not strict Forth** (the user wants a format ideal for call-graph recording, not a Turing-complete Forth program).
+- **Postfix** (per user: "I want a post-fix heiarchy"): stack-based, no delimiters to count.
+- **Length-prefixed lists** (standard postfix solution for nesting): `N list` consumes N items, unambiguous.
+- **Trivial parser** (~30 lines: split + walk + evaluate tagged words against a known arity table).
+- **Compact**: ~30-40% fewer characters than JSON for the same data.
+- **Streamable**: no need to parse the whole file to find a record; you can scan for tags.
+- **Extensible**: add new metric types by adding new tagged words (`metric(name value sample_size)`, `histogram(buckets)`, etc.).
+
+## Verification (TDD per `conductor/workflow.md`)
+
+Unit tests in `tests/test_code_path_audit.py`:
+
+- `CallGraph.add_edge` + `transitive_callees` correctness on a synthetic 5-node graph.
+- `ExpensiveOpIndex` detects each of the 7 cost classes on synthetic source.
+- `StateMutationIndex` detects each of the 5 mutation kinds on synthetic source.
+- `trace_action` produces an `ActionProfile` for a synthetic action whose expected cost is computable by hand.
+- Custom postfix `.dsl` output round-trips (parse_dsl(to_dsl(profile)) == in-memory structure).
+- Prefix tree renderer produces well-formed box-drawing output for the 3 per-action reports.
+- Markdown output is well-formed (header per section, table per category).

+## Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| Heuristic cost model is imprecise; reported "expensive" ops aren't actually expensive at runtime. | Medium | Medium (false positives dilute the report) | `EXPENSIVE_THRESHOLD` is a module-level constant; the runtime-profiling follow-up calibrates it. |
+| AST walking misses dynamic patterns (eval, getattr, decorator-driven dispatch). | Medium | Medium (under-estimates some calls) | Document the limitations in the report's caveats section; the runtime-profiling follow-up catches these. |
+| Mermaid diagrams exceed renderable size for deep actions. | Medium | Low (visualization only) | Default `max_depth=5` for `--mermaid`; full graph available as `.dsl`. |
+| The 3 actions' entry points are not exactly the functions the user has in mind. | Medium | Low (the report is the artifact; user can re-run with different entry points) | Document the chosen entry points in the report; CLI/MCP tool accepts any fully-qualified function name. |
+| Report is too large to review (thousands of expensive ops). | Low | Medium | Per-action scoping; default `--depth 5`; ranked optimization candidates in `summary.md` make the top-N obvious. |
+| Existing `derive_code_path` is the de-facto call-graph tool and the new one is redundant. | Low | Low (the new one is a strict superset) | `derive_code_path` stays as a thin wrapper around `code_path_audit.trace_action` for backward compat, OR gets a `@deprecated` shim. |
+| The 3 actions are not actually the user's top 3 (user might have meant a different 3). | Low | Low (the tool is generic; re-run with different actions is one CLI call) | CLI accepts any `Action`; user can re-run. |
+
+## Coordination with Pending Tracks
+
+This track has **no blockers** and **no conflicts**. It can ship independently of the 5 active planned tracks. **It enables** future refactors:
+
+| Pending track | Could use this analysis for... |
+|----------------|--------------------------------|
+| `qwen_llama_grok_integration_20260606` | Identifying redundant OpenAI-compatible request paths in `_send_*` functions |
+| `data_oriented_error_handling_20260606` | Showing the call paths the new `Result[T]` return values will thread through |
+| `data_structure_strengthening_20260606` | Pinpointing hot functions where the new type aliases matter most |
+| `mcp_architecture_refactor_20260606` | Identifying which sub-MCPs have the most expensive operations (file_io vs network vs ast) |
+| `test_batching_refactor_20260606` | Confirming which tests trigger the most expensive paths (to optimize test selection) |
+
+This track's analysis is **read-only** — it doesn't modify `src/`, doesn't change the public API, doesn't add tests to the existing test suite. The only new files are `src/code_path_audit.py` (the tool), `tests/test_code_path_audit.py` (the tests), and the report under `docs/reports/code_path_audit/2026-06-07/`.
+
+## Follow-up
+
+- **`pipeline_runtime_profiling_20260607`** (the user-requested follow-up; NOT in this track): adds a runtime profiling harness using the existing `src/performance_monitor.py` + a per-action test fixture. Measures real costs for the 3 actions. Calibrates the heuristic cost model (`EXPENSIVE_THRESHOLD` + per-class weights). Catches "things that aren't easy to resolve statically" — import cost, JIT effects, GC pauses, C-extension call cost (imgui-bundle, tree-sitter native), decorator-driven dispatch. Output: `scripts/runtime_profiler.py` + updated `code_path_audit.py` cost model.
+- **`pipeline_pruning_20260607`** (the second follow-up; NOT in this track): implements the high-priority optimization candidates surfaced by this track's report. Will be scoped AFTER this track ships, since the report itself defines what to prune.
+
+## Out of Scope
+
+- **MMA worker spawn action** (deferred per user — keeping MMA cold until the 1:1 discussion UX is dogfooded in a few projects).
+- **Implementing the optimization fixes** (deferred to `pipeline_pruning_20260607`).
+- **Runtime profiling** (deferred to `pipeline_runtime_profiling_20260607` per the user's explicit ask).
+- **Other major actions** beyond AI message, save/load, GUI startup.
+- **C-extension call costs** (deferred to runtime profiling).
+- **Decorator-driven call dispatch** (deferred to runtime profiling).
+- **`simulation/*` and `tests/*` directories** (analysis is `src/`-only for this track; can be extended later).
+- **Modifying `src/`** (read-only analysis).

+- **`conductor/tracks/nagent_review_20260608/report.md` §15** (Pitfalls #2 and #4, "provider-specific history in process globals" and "AI client is a stateful singleton") — the audit's `state_mutations` index will surface both of these in the post-4-tracks `src/ai_client.py`; the optimization candidates should specifically address them.
+- **`docs/transcripts/wo84LFzx5nI_big_oops_casemuratori.txt`** — full transcript of Casey Muratori's "The Big OOPs" talk, loaded 2026-06-08 for context. The historical genealogy (Stroustrup, Kay, Simula, Hoare) grounds the audit's "entity-hierarchy fingerprint" heuristic (above). Specifically, Hoare's 1966 "Record Handling" paper introduced discriminated unions — which Simula kept (as `inspect`) but C++ removed. The audit's `actions/ai_message_lifecycle.tree` should be checked for `if/else` chains that *would be* a discriminated union if `Result[T]` were threaded through.
+- **`docs/transcripts/i-h95QIGchY_assuming_as_much_as_possible_andrewreece.txt`** — full transcript of Andrew Reece's "Assuming as Much as Possible" talk, loaded 2026-06-08 for context. Reece's "Xar" data structure (8-byte header, power-of-2 chunks, bitwise divmod, no `realloc` copy) is the *exemplar* for the chunkification-candidate heuristic. The `summary.md` of the audit's report should note the Xar pattern as a possible optimization target for any function in the hot path that does append-heavy work on a list of uniform items.
+- **`docs/ideation/ed_chunk_data_structures_20260523.md`** — user's chunk-based-data-structure ideation (May 2026). The 5-image archive is the source of the "chunkification candidates" heuristic. Specifically, the user notes: *"if my chunk size is 1,000 elements, but I only have 5 elements to store, aren't I wasting a massive amount of memory?"* — the audit should distinguish *real* chunkification candidates (uniform data, hot path, large N) from *false* chunkification candidates (small N, low frequency, polymorphic data).
+- **`docs/reports/computational_shapes_ssdl_digest_20260608.md`** — the SSDL digest synthesizing the 4-source computational-shapes thinking. The audit's `actions/<action>.tree` and `actions/<action>.mmd` outputs *are* computational-shape visualizations; the SSDL vocabulary (6 primitives + 7 modifiers) is the conceptual model the audit's tree renderer should follow.

+## Hard Rules (enforced in the 3 refactored files)
+
+These are non-negotiable in `src/mcp_client.py`, `src/ai_client.py`, and `src/rag_engine.py`:
+
+- **`Optional[T]` return types are FORBIDDEN** in the 3 refactored files. Use `Result[T]` (with `NIL_T` singleton if needed) instead. Rationale: `Optional[T]` is the sum type `Union[T, None]` that Fleury's framework replaces. Mixing the two patterns reintroduces the bifurcation the convention is designed to remove.
+- **Function return types must be `Result[T]` for any function that can fail at runtime.** A function that can't fail (e.g., `get_name() -> str`) doesn't need a `Result`. The classification is "can this return a different value under different runtime conditions?" If yes, `Result`. If no, plain return type.
+- **Catch SDK exceptions at the boundary only.** Inside the 3 refactored files, the only place an exception is caught is at the SDK call site (e.g., `_send_<vendor>_result()` wrapping the SDK call). Internal `try/except` is reserved for converting `OSError`, `PermissionError`, and similar I/O exceptions to `ErrorInfo` at the mcp_client tool boundary.
+
+The verification script `scripts/audit_optional_in_3_files.py` (added by this track, see Plan Task 1.6) enforces the `Optional[X]` rule by failing CI if any new `Optional[X]` appears in the 3 refactored files.

 **2. Placeholder scan:** No "TBD", "TODO", "implement later", "add appropriate error handling", "Similar to Task N" in the plan. The 8 providers' refactor in Task 3.4 has the same body pattern as the generic example; the implementer copies it for each provider (no need to write 8 copies of the same boilerplate in the plan; the pattern is explicit enough).

+#### 3.1.1 3rd-Party Validation (independent corroboration)
+
+The "errors are data, not control flow" thesis is independently supported by two other practitioners in the data-oriented / C-style community:
+
+- **Timothy Lottes (@NOTimothyLottes), 2026-06-07** — [X thread]. "Error codes, many APIs get these so wrong. For example aliasing the same code with multiple meaning so the user has zero idea what actually went wrong and what needs fixing." Lottes's pattern: a force-no-inline `ERROR[__line__]: _code_` exit point where the exit code IS the source line number. Errors are zero-cost at init time; "all my error checks are init time (low cost) and only fail just results in this common Err() with printed {line, code} exit path." This track's `Result` dataclass is the Python analog: an `ErrorInfo` with a `source` field and an optional `location: int` (future enhancement) carries the same diagnostic information Lottes's exit code does.
+
+  **Lottes's anti-pattern warning, applied to `ErrorKind`:** "aliasing the same code with multiple meaning" — each `ErrorKind` value has exactly one meaning. Adding a new kind for a new failure mode is preferred over overloading an existing one. The 11 enum values (`NETWORK`, `AUTH`, `QUOTA`, `RATE_LIMIT`, `BALANCE`, `PERMISSION`, `NOT_FOUND`, `INVALID_INPUT`, `NOT_READY`, `UNKNOWN`, `CONFIG`, `INTERNAL`) are the canonical set; if a new failure mode doesn't fit, add a new value, don't overload `UNKNOWN`.
+
+- **Valigo (@valigotech), "Exceptions are horrifying", 2026-06-07** — YouTube, 14 min. Exceptions "mess with control flow in very weird ways"; the caller can no longer read top-to-bottom and predict what happens. TypeScript's failure to express "this throws" is what motivated the Effect library (a Rust-style `Result<T, E>` port). "Modern languages without legacy baggage move away from exceptions — Rust, Jai, Zig, Odin." JavaScript's worst abuse: throwing a `Promise` for Suspense. "Every time you open a website, you see like six different spinners all over the place."
+
+  **Valigo's anti-pattern warning, applied to this codebase:** `ErrorInfo` is a value, never a thrown object. Do not raise it; do not yield it from a generator; do not pass it as a side-effect return; do not use it as a `Promise` rejection value. It is a data value, period. The Hook API's `/api/ask` Remote Confirmation Protocol (a long-running challenge/response) is conceptually similar to Suspense but is **not** an exception mechanism — it returns a JSON object with a `request_id` and a status, not a thrown value. Future code that adds new cross-thread communication patterns must not smuggle exception-like control flow under the guise of a "request."

+rg "_send_(gemini|anthropic|deepseek|minimax|gemini_cli|qwen|llama|grok)\(" src/ -n # direct callers of private _send_<vendor>() — should be 0 post-qwen-track

+
+The follow-up `public_api_migration_20260606` track uses these as its starting baseline. The `no_new_optional_in_3_files` verification criterion is "the count does not grow during this track" — verified by re-running the grep at Phase 2, 3, 4, 5 checkpoints.

The per-provider history globals (`_anthropic_history`, `_deepseek_history`, `_minimax_history` at `ai_client.py:123-132`) are the **specific pattern** that the `ErrorKind.PROVIDER_HISTORY_DIVERGED_FROM_UI` new error kind (added 2026-06-08) is designed to surface. Per `guide_ai_client.md §"State"`, the per-provider-lock pattern is the established convention.
-- `docs/guide_mcp_client.md` — current MCP client architecture; will be updated in Phase 5.
+- `docs/guide_mcp_client.md` — current MCP client architecture; will be updated in Phase 5. Per the 2026-06-08 docs refresh, `guide_mcp_client.md` documents the 3-layer security model (Allowlist Construction → Path Validation → Resolution Gate) that the mcp_client refactor must preserve. The new `Result` return type must not weaken the 3 layers.
-- `conductor/product-guidelines.md` "Modular Controller Pattern" — the convention this track extends (Data-Oriented Error Handling is a new top-level convention in the same family).
+- `docs/guide_state_lifecycle.md` — added 2026-06-08. The 3 per-thread + 7-lock pattern documented in §4 ("State Synchronization Across Threads") is what the `ai_client` refactor's state-delegation regression tests must exercise.
-- `conductor/tracks/qwen_llama_grok_integration_20260606/` — the previous track that introduced the "data-oriented" framing; this track extends that philosophy to error handling.
+- `docs/guide_discussions.md` — added 2026-06-08. The 23-operation matrix (A1-A7 + B1-B11 + C1-C5) is the *user-facing* source of truth for what the per-entry edit operations do. The provider-history-divergence issue (Pitfall #4 from the nagent_review) is exactly that: user edits `disc_entries[i].content` via A1, but `ai_client._<provider>_history` is not updated. The follow-up `public_api_migration_20260606` is the natural moment to fix this.
+- `docs/guide_context_aggregation.md` — added 2026-06-08. The `aggregate.py:109 build_discussion_section` consumes the `disc_entries` list. If the entries are edited via A1, the section regenerates correctly. If the provider history is *not* updated, the next LLM call still sees the old history. The `Result` pattern from this track is the natural carrier for the "diverged" signal.
+- `conductor/tracks/qwen_llama_grok_integration_20260606/` — the previous track that introduced the "data-oriented" framing; this track extends that philosophy to error handling. The qwen track's `send_openai_compatible()` helper is *expected* to return `Result` from day 1 (per the coordination note in the qwen spec §3.1) — this is a real concrete dependency.
+- `conductor/tracks/mcp_architecture_refactor_20260606/` — the next major track (after this one). Each sub-MCP's `invoke()` returns `Result[str, ErrorInfo]` per the mcp spec; this track defines the `Result` type that the mcp refactor uses. Coordination: this track ships *before* the mcp refactor can ship Phase 4 (extract Python) onward.
+- `conductor/tracks/nagent_review_20260608/report.md` — added 2026-06-08. §15 Pitfalls #2 and #4 (per-provider history globals, stateful singleton) and Pitfall #9 (sub-conversations) inform this track's risk register. Pitfall #4 specifically motivates the new `ErrorKind.PROVIDER_HISTORY_DIVERGED_FROM_UI` kind.
+- `conductor/tracks/nagent_review_20260608/nagent_takeaways_20260608.md` — added 2026-06-08. §9 ("Edit-the-input, not the output") describes the same provider-history-divergence problem; the `Result` pattern + the new error kind are the data-oriented solution.
 - `conductor/tracks/test_batching_refactor_20260606/` — the previous track that established the "tier-based" pattern; this track uses the same convention format (spec + metadata + state + plan).

Per the 2026-06-08 docs refresh, the FileItem schema (9 fields + `__post_init__` normalizer) is documented in `docs/guide_context_aggregation.md §"The FileItem Schema (Full)"`.
+- `docs/guide_context_aggregation.md` — added 2026-06-08. The `aggregate.py:142 build_file_items` function consumes the `FileItem` list; the `FileItems: TypeAlias` is the consumer-side type.
+- `docs/guide_discussions.md` — added 2026-06-08. The entry dict shape (the `HistoryMessage` alias) is documented here. The shape has at least 7 fields (`{role, content, collapsed, ts, thinking_segments?, usage?, read_mode?}`) plus optional extras. The alias docstring notes the dict is *open* — extra keys are allowed.
+- `docs/guide_state_lifecycle.md` — added 2026-06-08. The `App.__getattr__`/`__setattr__` state delegation (per `gui_2.py:666-675`) and the `UISnapshot` capture (`gui_2.py:735-789`) are the *correctness* the alias-typed code must preserve; aliases are TYPE-LEVEL ONLY and don't change runtime behavior.
+- `conductor/code_styleguides/error_handling.md` (created in the data_oriented_error_handling_20260606 track) — the convention for `Result` types; the new type-aliases convention lives alongside. The two conventions are *complementary*: aliases name the *data* (`T` in `Result[T]`); `Result` wraps the *control flow*. See §3.5 of the spec.
 - `conductor/product-guidelines.md` "Data-Oriented Error Handling" — the convention this track extends (Data Structure Strengthening is a new top-level convention in the same family).
-- `conductor/tracks/data_oriented_error_handling_20260606/` — the previous track that established the convention format; this track uses the same pattern.
+- `conductor/tracks/data_oriented_error_handling_20260606/` — the previous track that established the convention format; this track uses the same pattern. The new `ProviderHistoryMessage` alias (added 2026-06-08) is the *concrete manifestation* of nagent_review Pitfall #4 (provider-history divergence) — the user's edits to the `HistoryMessage` (UI layer) are a different layer from the `ProviderHistoryMessage` (SDK layer), and conflating them perpetuates the bug.
+- `conductor/tracks/mcp_architecture_refactor_20260606/` — the parallel major track. `mcp_client.py` is currently listed as "UNCHANGED (only 9 weak sites; below the threshold)" in the module layout, but the refactor will touch it heavily; the audit script should be re-run after the mcp refactor lands, and a follow-up type-aliases pass on mcp_client.py is the natural next target.
+- `conductor/tracks/nagent_review_20260608/report.md` — added 2026-06-08. §6 (per-file memory) and §15 Pitfall #4 (provider history divergence) directly motivate the `HistoryMessage` vs `ProviderHistoryMessage` split in §3.1 of this spec.
+- `conductor/tracks/nagent_review_20260608/nagent_takeaways_20260608.md` — added 2026-06-08. §9 (edit-the-input, not the output) describes the bug the new alias split addresses.

+# Track Specification: Test-Era Docs Sync (2026-06-10)
+
+## Overview
+End-state cleanup and full docs sync following the 4-day test-hell saga (regression_fixes → test_infrastructure_hardening → mma_tier_usage_reset_fix → rag_phase4_sync_fix → workspace_path_finalize). Goal: the next Tier 2 agent engaging `qwen_llama_grok_integration_20260606` has pristine, drift-free docs to read.
+
+## Current State Audit (as of 2026-06-10, baseline `f93dac7d`)
+
+### Code deltas since 2026-06-02 docs refresh
+- `src/app_controller.py` — 4 mma_tier_usage/flush_to_project/LazyManager bug fixes
+- `src/rag_engine.py` — rag_config reset, _validate_collection_dim (dim-mismatch recursion), embedding init error status, CWD fallback in index_file
+- `src/gui_2.py` — __getattr__ fix (silent-None bug from bcdc26d0), warmup infrastructure
+- `src/ai_client.py` — _require_warmed lazy-loading refactor (8 commits)
+- `src/api_hooks.py` — /api/warmup_status, /api/warmup_wait, /api/warmup_canaries, /api/startup_timeline endpoints
+- `src/workspace_manager.py` — WorkspaceProfile ini_content str-vs-bytes contract
+- `src/simulation/sim_context.py` — defensive setdefault('paths', [])
+- `tests/conftest.py` — _LiveGuiHandle, _check_live_gui_health, live_gui_workspace, _reset_clean_baseline, xdist O_EXCL mutex, watchdog 600s/900s
+- `pyproject.toml` — clean_baseline marker, watchdog timeout
+- `scripts/` — audit_main_thread_imports.py, audit_weak_types.py, run_tests_batched.py (tier-based)
+
+### Already done (no action)
+- `docs/guide_testing.md` was updated 6/9 5:03 PM (commit `cb525519`) — covers _LiveGuiHandle + live_gui_workspace + clean_baseline marker
+- `docs/reports/test_bed_health_20260609.md` and `docs/reports/test_infrastructure_hardening_batch_green_20260610.md` are committed
+- `conductor/code_styleguides/workspace_paths.md` was added 6/9
+- 3 of 6 lessons are already in `AGENTS.md` Process Anti-Patterns
+
+### Gaps to fill (this track's scope)
+**20 critical, 21 moderate, 12 minor drift items** across 11 doc files (full inventory in track plan §"Audit Findings").
+
+**End-state cleanup:**
+- 4 track folders in `conductor/tracks/` need archiving: test_infrastructure_hardening_20260609, mma_tier_usage_reset_fix_20260610, rag_phase4_sync_fix_20260610, workspace_path_finalize_20260609
+- 1 `conductor/archive/` directory needs to be created (does not exist on disk)
+- 4 `state.toml` files need `status`/`last_updated` updates
+- 4 `metadata.json` files need `status: spec` → `status: shipped`
+- `conductor/tracks.md` row 1 needs to move from Active to Archived
+- `conductor/index.md` "Recently Shipped" needs new entry
+
+**Lessons capture:**
+- Lesson 5 (chroma cache path) → new `conductor/code_styleguides/chroma_cache.md`
+- Lessons 1, 2, 3, 6 → additions to `conductor/product-guidelines.md` and `conductor/workflow.md`
+
+## Goals
+1. All 11 doc files with drift fixed to match current `src/` behavior
+2. All 4 test-hell lineage tracks properly archived with consistent state
+3. 4 lessons placed in durable locations (1 new styleguide + 2 file additions)
+4. `tracks.md` + `index.md` reflect the new archive reality
+5. All audit scripts still report 0 regressions
+6. Total time: ~90-120 min
+
+## Functional Requirements
+- Doc edits must be grounded in `git diff` against baseline `f93dac7d`
+- Doc edits must use `manual-slop_edit_file` for surgical precision (no native `edit`)
+- Each doc file gets at most 1 atomic commit (multiple drift items in one commit per file)
+- `conductor/tracks.md` row 1 must move to a "Late June 2026: Test Infrastructure Hardening" archived section
+- `conductor/archive/` must be created (the 71 archive links in tracks.md have never been populated)
+
+## Non-Functional Requirements
+- No new audit violations (existing audit scripts must still report 0)
+- No scope creep: only the 11 drift files + 4 tracks + lessons files are in scope
+- All changes must follow the project's 1-space indentation for any Python touched (none expected)
+- Each commit message ≤ 15 lines (per AGENTS.md "Verbose-Commit-Message" rule)
+
+## Architecture Reference
+- `docs/guide_architecture.md` — Threading model, event system, AI client multi-provider
+- `docs/guide_app_controller.md` — Controller state, managers, Hook API
+- `docs/guide_rag.md` — RAG engine, vector store, embedding providers
+- `docs/guide_gui_2.md` — App class, render functions, hot reload
+- `docs/guide_testing.md` — Conftest fixtures, live_gui pattern, audit scripts
+- `docs/Readme.md` — Docs index (30 guides)
+
+## Out of Scope
+- Other "Active" tracks (manual_ux_validation_20260608, ui_polish_five_issues, gencpp_dogfood_feedback_20260510, etc.) — these are not test-hell lineage
+- Migrating any source code
+- Creating new audit scripts
+- `qwen_llama_grok` planning — separate session
+- Code-path audit (already on the backlog)

+# License & CVE Audit Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build `scripts/audit_license_cve.py` — a single audit script that checks third-party deps (in `pyproject.toml` + `uv.lock` transitive tree) for license compliance + known CVEs + version-pinning + SPDX source-headers. Then tilde-pin all deps, delete `requirements.txt`, regenerate `uv.lock`, add `--strict` mode + baseline file (CI gate). One script, one CI gate, one report.
+
+**Architecture:** Single audit script in `scripts/`. No new pip deps in the project (pure stdlib: `importlib.metadata`, `tomllib`, `pathlib`; subprocess call to `pip-audit` is an optional dev tool). TDD pattern: each check function has a unit test with a synthetic fixture, then the real implementation, then commit. The 4 commits per the spec: (1) audit script + initial report, (2) tilde-pin + lock regen + delete requirements.txt, (3) --strict mode + baseline file, (4) tracks.md update.
+
+**Tech Stack:** Python 3.11+, `importlib.metadata` (stdlib), `tomllib` (stdlib), `pathlib` (stdlib), `re` (stdlib), `subprocess` (stdlib, for `pip-audit`), `pytest` (already a dev dep). No new pip deps in the project.

+
+- [ ] **Step 1.6.6: Conductor - User Manual Verification (per workflow.md)**
+
+Ask the user to confirm the initial report is correct before proceeding to Phase 2 (the cleanup).
+
+---
+
+## Phase 2: Tilde-pin + lock regen + delete requirements.txt (Commit 2)
+
+**Files:** `pyproject.toml`, `uv.lock`, `requirements.txt` (delete).
+
+This phase is one commit. The cleanup is mechanical: read `uv.lock` to discover current versions, rewrite `pyproject.toml` with `~X.Y.Z` for every dep, regenerate the lock, delete the redundant file.
+
+- [ ] **Step 2.1: Read `uv.lock` to discover current versions of all direct deps**
+
+```bash
+uv run python -c "
+import tomllib
+import re
+# Parse pyproject.toml for direct dep names
+with open('pyproject.toml', 'rb') as f:
+  pyproject = tomllib.load(f)
+direct_deps = []
+for dep in pyproject.get('project', {}).get('dependencies', []):
+  name = re.split(r'[<>=!~;\\[ ]', dep, maxsplit=1)[0].strip()
+  direct_deps.append(name)
+# Parse uv.lock for current versions
+import tomllib as t
+with open('uv.lock', 'rb') as f:
+  lock = t.load(f)
+for pkg in lock.get('package', []):
+  if pkg['name'] in direct_deps:
+  print(f\"{pkg['name']}=={pkg['version']}\")
+"
+```
+
+Expected output: a list of `name==version` lines for all 14 direct deps.
+
+- [ ] **Step 2.2: Rewrite `pyproject.toml` with `~X.Y.Z` for every dep**
+
+For each dep, replace the existing version specifier with `~X.Y.Z` where X.Y.Z is the version from `uv.lock`. Example:
+
+```toml
+# Before
+"imgui-bundle",
+"pyopengl>=3.1.10",
+
+# After
+"imgui-bundle~=1.0.0",
+"pyopengl~=3.1.10",
+```
+
+(The exact version per dep is read from the previous step's output. The implementer does this edit by hand or with a Python script that reads `uv.lock` and rewrites `pyproject.toml`.)
+
+- [ ] **Step 2.3: Regenerate `uv.lock`**
+
+Run: `uv lock`
+Expected: updates `uv.lock` to reflect the new `pyproject.toml` bounds.
+
+- [ ] **Step 2.4: Delete `requirements.txt`**
+
+Run: `Remove-Item -LiteralPath requirements.txt -Force`
+Expected: file is gone; `uv.lock` is the canonical lock.
+
+- [ ] **Step 2.5: Re-run the audit to confirm pin violations are gone**
+
+Run: `uv run python -m scripts.audit_license_cve --report-dir docs/reports/license_cve_audit --date 2026-06-07`
+Expected: license + pin violations may still exist (if any deps are GPL/unknown), but no PIN_MISSING violations. The new `final.md` is written.
+
+- [ ] **Step 2.6: Commit Phase 2 (Commit 2)**
+
+```bash
+git add pyproject.toml uv.lock
+git commit -m "chore(deps): tilde-pin all deps; delete requirements.txt
+
+Every direct dep in pyproject.toml now has a ~X.Y.Z bound
+(patch-only). The 7 unconstrained deps (imgui-bundle,
+anthropic, google-genai, openai, fastapi, mcp, uvicorn)
+get explicit tilde bounds discovered from uv.lock. The 6
+>=X.Y.Z deps are normalized to tilde-style. tomli-w gets
+its first bound.
+
+uv.lock is regenerated. requirements.txt is deleted (was
+redundant with uv.lock; the uv project uses uv.lock as
+the canonical lock file).
+
+Re-running the audit confirms no PIN_MISSING violations.
+License and CVE checks still find their respective issues
+(if any); those are handled by the policy in Phase 1's
+script and (in the future) by Phase 3's --strict gate."

+- [ ] **Step 3.3: Run the tests**
+
+Run: `uv run pytest tests/test_audit_license_cve.py -q 2>&1 | Select-Object -Last 5`
+Expected: PASS. (~29 tests now pass — 27 from Phase 1 + 2 strict/baseline tests.)
+
+- [ ] **Step 3.4: Verify the gate end-to-end**
+
+Run: `uv run python -m scripts.audit_license_cve --strict --report-dir docs/reports/license_cve_audit --date 2026-06-07; echo "exit: $?"`
+Expected: exit 0 (current violations == baseline). If a new violation appears in the future, exit 1 (gate fails).
+
+- [ ] **Step 3.5: Commit Phase 3 (Commit 3)**
+
+```bash
+git add scripts/audit_license_cve.baseline.json scripts/audit_license_cve.py tests/test_audit_license_cve.py

+# Track: License & CVE Audit (Dependency Compliance)
+
+**Status:** Spec approved 2026-06-07
+**Initialized:** 2026-06-07
+**Owner:** Tier 2 Tech Lead
+**Priority:** High (compliance + security; CI gate)
+
+---
+
+## Overview
+
+Build `scripts/audit_license_cve.py` — a single audit script that checks third-party dependencies (in `pyproject.toml` + `uv.lock` transitive tree) for: (1) license compliance against the project's policy, (2) known CVEs (via `pip-audit` subprocess), and (3) version-pinning (every direct dep must have a `~X.Y.Z` bound). The script also scans source-file license headers (`SPDX-License-Identifier`) in `src/**/*.py` and `scripts/**/*.py`. Then apply the fixes: tilde-pin all direct deps, delete `requirements.txt` (redundant with `uv.lock`), regenerate `uv.lock`, add `--strict` mode + baseline file (CI gate). One script, one CI gate, one report.
+
+The track is **scope-limited to third-party dependencies**. The project's own LICENSE file and SPDX/Copyright headers are explicitly OUT OF SCOPE — the user reserves all rights to the repo and has not picked a project license yet. The audit reports third-party state only; it does not assert or imply a project license, and it does not create a `LICENSE` file.
+
+## Current State Audit (as of `9796fe27`)
+
+- `pyproject.toml` has 14 direct deps with **mixed pinning**:
+  - 7 unconstrained: `"imgui-bundle"`, `"anthropic"`, `"google-genai"`, `"openai"`, `"fastapi"`, `"mcp"`, `"uvicorn"`
+  - 6 with `>=X.Y.Z`: `"pyopengl>=3.1.10"`, `"tree-sitter>=0.25.2"`, `"tree-sitter-python>=0.25.0"`, `"tree-sitter-c>=0.23.2"`, `"tree-sitter-cpp>=0.23.2"`, `"psutil>=7.2.2"`, `"chromadb>=1.5.8"`
+  - `"tomli-w"`, `"pytest-timeout>=2.4.0"`
+- `uv.lock` exists; `requirements.txt` exists (duplicates lock — will be removed)
+- No `LICENSE` file in repo root (user's chosen posture: all rights reserved; the audit reports this as informational, not a violation)
+- No source-file `SPDX-License-Identifier` headers in `src/**/*.py` or `scripts/**/*.py` (informational note; not a violation — the user hasn't picked a project license yet)
+- No `vendor/`, `third_party/`, or vendored C/C++ in the repo tree (the scan is defensive for the future)
+- 0 existing license/CVE audit tools in `scripts/`
+- The 3 existing audit scripts (`audit_main_thread_imports.py`, `audit_weak_types.py`, `check_test_toml_paths.py`) follow the project pattern of `scripts/audit_<name>.py` + `scripts/audit_<name>.baseline.json` + `--strict` mode for CI gates (per `conductor/workflow.md` "Audit Script Policy"). The new track follows the same pattern.
+
+### Already Implemented (DO NOT re-implement; KEEP / build on)
+
+1. **The 3 existing audit scripts** in `scripts/`. They define the project pattern for audit + CI gate. The new `scripts/audit_license_cve.py` follows the same shape.
+2. **`uv.lock`** — the canonical lock file for the project. The audit reads it for transitive resolution.
+3. **`importlib.metadata`** (Python 3.11+ stdlib) — gives `License` and `License-Expression` per installed distribution. No new pip dep needed for the license check.
+4. **`tomllib`** (Python 3.11+ stdlib) — parses `pyproject.toml`. No new pip dep needed for the pin check.
+5. **`pip-audit`** (PyPA tool) — invoked as a subprocess for the CVE check. `pip-audit` itself is NOT a project dep; it's installed via `uv tool install pip-audit` or `uvx pip-audit` if the user wants the CVE check. The script detects missing `pip-audit` and logs a warning; license + pin checks still run.
+
+### Gaps to Fill (this track's scope)
+
+- `scripts/audit_license_cve.py` (~300 lines, 3 internal checks + `--strict` + `--dump-baseline`)
+- `scripts/audit_license_cve.baseline.json` (zero-violation post-cleanup state for `--strict` mode)
+- `docs/reports/license_cve_audit/2026-06-07/initial.md` and `final.md` (the human-readable reports)
+- Updates to `pyproject.toml` (tilde-pin every direct dep)
+- Updated `uv.lock` (regenerated)
+- Deletion of `requirements.txt`
+- `tests/test_audit_license_cve.py` (TDD unit tests)
+
+## Goals
+
+1. **Single audit script** that runs all four checks (license + CVE + pin + source-header) and emits a unified report.
+2. **CI gate** via `--strict` mode + baseline file. Mirrors the 3 existing audit scripts. Fails on any new violation OR any new CVE.
+3. **Tilde-pin every direct dep** in `pyproject.toml` (`~X.Y.Z` = `>=X.Y.Z,<X.(Y+1).0`).
+4. **Delete `requirements.txt`** (duplicates `uv.lock`; redundant in a `uv` project).
+5. **Re-run `uv lock`** to refresh the lock file with the new bounds.
+6. **Document the non-OSI / restricted-source category** in the policy table of the script (so future contributors understand why these licenses are blocked).
+7. **Preserve the user's "all rights reserved" posture** — no `LICENSE` file is created; no project-level SPDX headers are added.
+
+## Non-Goals
+
+- The project's own `LICENSE` file (user's decision; not creating one).
+- The project's own `SPDX-License-Identifier` / `Copyright` headers (user's decision; not adding or modifying).
+- Any recommendation on what license the user should pick for the project.
+- Patching CVEs in transitive deps (the track REPORTS; the user decides whether to wait for upstream or replace).
+- Auto-bumping versions to address CVEs (manual decision; the track reports, the user acts).
+- Modifying any third-party code already in the repo (none currently; the scan is defensive for the future).
+- License/header updates to vendored C/C++ (none currently vendored; the scan is defensive).
+- The local-rag optional dependency group (`sentence-transformers`); covered by the same audit but pinning happens in the same `pyproject.toml` edit.
+
+## Architecture
+
+**`scripts/audit_license_cve.py`** — single audit script, ~300 lines. No new pip dep required (stdlib + subprocess to `pip-audit`).
+
+### Public API (CLI)
+
+```bash
+uv run python scripts/audit_license_cve.py [--src src] [--scripts scripts] \
+    [--report-dir docs/reports/license_cve_audit] [--date YYYY-MM-DD] \
+    [--strict] [--dump-baseline]
+```
+
+- **Default mode:** informational. Prints violations to stdout (line-per-violation format). Writes markdown report to `<report-dir>/<date>/initial.md` or `final.md`.
+- **`--strict` mode:** exits non-zero if violations > baseline. For CI.
+- **`--dump-baseline`:** writes the current violation set as the new baseline. For intentional changes (e.g., a new dep is added; the user accepts its license).
+
+### Internal structure (3 checks + 1 scan)
+
+```python
+def check_licenses() -> list[Violation]: ...     # iterates dist.metadata; classifies
+def check_cves() -> list[Violation]: ...          # subprocess pip-audit; parses JSON
+def check_pins() -> list[Violation]: ...          # tomllib parse; flag missing/loose pins
+def check_source_headers() -> list[Violation]: ... # pathlib rglob; SPDX regex
+
+def main():
+    violations = []
+    for check in (check_licenses, check_cves, check_pins, check_source_headers):
+        violations.extend(check())
+    for v in violations:
+        print(v.format_stdout())     # parseable line-per-violation
+    write_markdown_report(violations)
+    if args.strict and len(violations) > len(load_baseline()):
+        sys.exit(1)
+    if args.dump_baseline:
+        dump_baseline(violations)
+```
+
+### Cost model (the 4 checks)
+
+| Check | Mechanism | New deps? |
+|-------|-----------|-----------|
+| **License** | `importlib.metadata.distribution(name).metadata.get("License")` + `License-Expression` (Python 3.11+ stdlib). For each direct + transitive dep, classify the license string against the policy table. Unknown / unparseable / missing → violation. | None (stdlib) |
+| **CVE** | Subprocess call to `pip-audit --format=json --strict` (a `uv tool install pip-audit` dev tool; the project itself doesn't depend on it). If `pip-audit` isn't installed, log a warning + skip the CVE check; license + pin still run. Air-gapped CI: CVE check returns no results (not a failure). | None in `pyproject.toml`; `pip-audit` is an optional dev tool. |
+| **Version pin** | `tomllib.load(pyproject.toml)` (stdlib). For each entry in `[project].dependencies`, check the version specifier. Flags: (a) no specifier at all, (b) no lower bound. Accepts any lower bound as a soft check (the user's choice is tilde, but the script doesn't enforce tilde specifically — it enforces "has a lower bound"). | None (stdlib) |
+| **Source header** | `pathlib.Path(src_dir).rglob("*.py")`, read first 20 lines of each, regex-look for `SPDX-License-Identifier:` (case-insensitive). If present and in the blocklist → violation. If no SPDX → no violation (informational note). | None (stdlib) |
+
+## License Policy (encoded in the script)
+
+### Allowlist (permissive or weak copyleft, import-safe in Python)
+
+- **Permissive:** MIT, BSD (2-clause + 3-clause), Apache 2.0, ISC, Unlicense, Zlib, Python-2.0, 0BSD, PSF-2.0
+- **Weak copyleft (import-safe in Python):** LGPL (2.1, 3.0), MPL-2.0
+- **Public domain:** CC0, Unlicense, WTFPL
+
+(The script's allowlist is the canonical source of truth for the per-license table; see `scripts/audit_license_cve.py` for the current list. New licenses can be added by editing that table; no spec change needed.)
+
+### Blocklist (non-permissive / restricted-source)
+
+The blocklist is for licenses that are **non-OSI** or that impose **restrictions beyond standard copyleft terms** (permissive or copyleft). The unifying technical property: the license restricts how downstream users can use the software in ways that standard open-source licenses do not.
+
+| License | Specific restriction |
+|---------|---------------------|
+| **GPL** (any version) | Strong copyleft; viral licensing; downstream users must release derivative works under GPL |
+| **AGPL** (any version) | Network copyleft; downstream SaaS users must release source under AGPL |
+| **SSPL** (MongoDB, 2018) | "If you offer the software as a service, you must release the entire stack under SSPL" — broad service-provider trigger |
+| **BSL / BUSL** (Business Source License) | Source-available with a delayed open-source conversion; competitive-use restriction during the delay |
+| **Commons Clause** | Addendum to an open-source license; adds "you may not sell the software" — targets SaaS reselling |
+| **Elastic License v2** (Elastic NV, 2021) | "You may not offer the software as a managed service that competes with Elastic" |
+| **Unknown / unparseable** (e.g., `UNKNOWN`, `Custom`, `see AUTHORS`) | Not classifiable; flagged for manual review; never auto-pass |
+| **Missing license metadata** | Catches packaging bugs |
+
+### Decision rule (in the script)
+
+```
+if license in BLOCKLIST: violation
+elif license in ALLOWLIST: pass
+else:  # unknown / unparseable / unclassified
+    violation (flag for manual review; never auto-pass)
+```
+
+The two lists are explicit, not heuristic. Adding a new license to either list is a one-line code change. The script's `--help` references the policy table for transparency.
+
+## Output Format
+
+### Stdout (line-per-violation, parseable)
+
+```
+LICENSE_VIOLATION pkg=foo license="GPL-3.0" via=bar==2.0
+CVE_FOUND pkg=baz cve_id=CVE-2024-12345 severity=high fix_versions=">=1.2.3"
+PIN_MISSING pkg=qux (no version specifier in pyproject.toml)
+SPDX_VIOLATION file=src/some_module.py license="GPL-3.0"
+```
+
+Each line is a stable parseable format; CI can grep for `VIOLATION|FOUND|MISSING` and `exit 1` on any match.
+
+### Markdown report (in `docs/reports/license_cve_audit/<YYYY-MM-DD>/`)
+
+- `initial.md` — the discovered violations (committed in Phase 1)
+- `final.md` — the post-cleanup state (committed in Phase 2, after tilde-pinning + lock regen)
+
+Structure:
+
+```markdown
+# License & CVE Audit — 2026-06-07
+
+## Top-level summary
+
+- License violations: 0
+- CVEs found: 0
+- Pinning issues: 0
+- SPDX violations in src/ or scripts/: 0
+
+## Notes
+
+- No `LICENSE` file in repo root — informational, not a violation. The project's own license posture is the user's call (currently all rights reserved).
+- No source-file `SPDX-License-Identifier` headers — informational, not a violation. The project's own copyright headers are the user's call.
+- pip-audit not installed → CVE check skipped. Install via `uv tool install pip-audit` to enable.
+
+## Per-violation table
+
+| Type | Package | License / CVE / Pin | Via |
+|------|---------|---------------------|-----|
+| ... | ... | ... | ... |
+```
+
+### Baseline file (`scripts/audit_license_cve.baseline.json`)
+
+Internal state for `--strict` mode. JSON because it matches the existing convention (`scripts/audit_weak_types.baseline.json`). Not the user-facing report; not in the output surface. Format:
+
+```json
+{
+  "schema_version": 1,
+  "baseline_violations": [],
+  "baseline_date": "2026-06-07",
+  "notes": "Zero-violation state after the tilde-pinning + lock regen in this track."
+}
+```
+
+`--strict` mode loads this file and fails CI if `len(current_violations) > len(baseline_violations)`. The user's intentional changes (e.g., adding a new dep with an acceptable license) are recorded by re-running with `--dump-baseline`.
+
+## Commit Structure (4 atomic commits, in order)
+
+```
+1. chore(audit): add license_cve audit script + initial report
+   - scripts/audit_license_cve.py (initial version, informational mode)
+   - docs/reports/license_cve_audit/2026-06-07/initial.md (the discovered violations)
+2. chore(deps): tilde-pin all deps; delete requirements.txt
+   - pyproject.toml (every direct dep gets ~X.Y.Z or stays as >=X.Y.Z)
+   - uv.lock (regenerated)
+   - requirements.txt (deleted; was redundant with lock)
+3. chore(audit): add --strict mode + baseline file (CI gate)
+   - scripts/audit_license_cve.py (extends with --strict + baseline diff)
+   - scripts/audit_license_cve.baseline.json (zero-violation post-cleanup state)
+4. conductor(tracks): mark License CVE Audit track complete
+   - tracks.md update
+```
+
+Each commit message includes a `git notes add -m "..."` summary per `conductor/workflow.md`.
+
+## Verification (TDD per `conductor/workflow.md`)
+
+Unit tests in `tests/test_audit_license_cve.py`:
+
+- License classifier: a known fixture package list with various licenses → correct classification (blocklist + allowlist + unknown).
+- Blocklist enforcement: each entry (GPL, AGPL, SSPL, BSL, BUSL, Commons Clause, Elastic v2, unknown, missing) → correctly flagged.
+- Allowlist enforcement: each entry (MIT, BSD, Apache 2.0, ISC, Unlicense, Zlib, Python-2.0, LGPL, MPL-2.0, CC0, WTFPL) → correctly passes.
+- Pin check: synthetic `pyproject.toml` with mixed pinning (no bound, `>=X.Y`, `~X.Y.Z`, exact) → correct flags.
+- Source header check: synthetic `.py` with `SPDX-License-Identifier: GPL-3.0` → flagged; with no SPDX → no violation.
+- `--strict` mode: violations > baseline → exit 1; violations == baseline → exit 0; new violation (delta > 0) → exit 1.
+- `--dump-baseline`: writes a baseline file matching the current violation set.
+
+## Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| Some packages' license metadata is missing or unparseable in `importlib.metadata` | High | Medium (false positives on unknown) | The policy treats `UNKNOWN` as violation → manual review catches the right answer; the report's notes section lists the unknowns explicitly |
+| `pip-audit` not installed in CI | Medium | Low (CVE check is a no-op) | Script detects missing `pip-audit` and logs a warning; license + pin checks still run |
+| Air-gapped CI can't reach OSV / PyPI advisory DBs | Medium | Low (CVE check returns no results) | Document; a follow-up could add offline CVE support, not in this track |
+| Pinning decisions are subjective (some deps deserve looser bounds than others) | Medium | Low (initial pass is conservative) | The pin check accepts any lower bound as a soft check; the user can loosen specific deps via the baseline file |
+| The baseline file becomes a "shadow ledger" — needs maintenance when intentional changes are made | Medium | Low (intentional) | Document the update workflow in the script's `--help`; `--dump-baseline` regenerates the baseline after an intentional change |
+| The project's own LICENSE absence might confuse a future contributor who doesn't know the user's posture | Low | Low | The report's notes section explicitly calls this out: "no LICENSE in repo root — informational, not a violation; project's own license is the user's call (currently all rights reserved)" |
+| A dep is added with a license that doesn't match the script's allowlist/blocklist (e.g., a new "BSL 2.0" variant) | Low | Low | The script's default rule (unknown = violation) catches it; the report's notes section surfaces it for review; one-line add to the appropriate list |
+
+## Follow-up
+
+- `air_gapped_cve_check_20260607` (NOT in this track): add offline CVE support for air-gapped CI environments that can't reach OSV / PyPI. The CVE check would ship a snapshot of the advisory DBs (or use a local mirror).
+- `cve_auto_remediation_20260607` (NOT in this track): when a CVE is found, auto-bump the dep to the fix version (within the pin range) and re-run the audit. Out of scope here; this track REPORTS, the user DECIDES.
+
+## Coordination with Pending Tracks
+
+This track has **no blockers** and **no conflicts** with the 5 active planned tracks. It modifies:
+
+- `pyproject.toml` (version pins; could affect resolution for any future track that depends on something)
+- `uv.lock` (regenerated; the lock file changes)
+- `requirements.txt` (deleted; was redundant with lock)
+- New: `scripts/audit_license_cve.py`, `scripts/audit_license_cve.baseline.json`, `docs/reports/license_cve_audit/2026-06-07/`
+
+It does NOT modify `src/`, `tests/`, or any of the 5 planned tracks' files. The deleted `requirements.txt` is a separate file from the 5 planned tracks' scope. Can ship independently and in parallel with the 5 planned tracks.
+
+The tilde-pinning in this track is a STRENGTHENING of the dep contract, not a loosening — it doesn't break any existing test or any other track's plan.
+
+## Out of Scope
+
+- The project's own `LICENSE` file (user's decision; the track will not create one).
+- The project's own `SPDX-License-Identifier` / `Copyright` headers in `src/` (user's decision; the track will not add or modify).
+- Any recommendation on what license the user should pick for the project.
+- Patching CVEs in transitive deps (the track REPORTS; the user decides whether to wait for upstream or replace).
+- Auto-bumping versions to address CVEs (manual decision; the track reports, the user acts).
+- Modifying any third-party code already in the repo (none currently; the scan is defensive for the future).
+- License/header updates to vendored C/C++ (none currently vendored; the scan is defensive).
+- The local-rag optional dependency group (`sentence-transformers`); covered by the same audit but pinning happens in the same `pyproject.toml` edit.
+
+## See Also
+
+- `conductor/workflow.md` "Audit Script Policy" — the convention this track follows.
+- `scripts/audit_main_thread_imports.py`, `scripts/audit_weak_types.py`, `scripts/check_test_toml_paths.py` — the 3 existing audit scripts; the new track follows the same shape.
+- `scripts/audit_weak_types.baseline.json` — the baseline file pattern (the new `scripts/audit_license_cve.baseline.json` mirrors this).
+- [OSI Approved Licenses](https://opensource.org/licenses/) — the de facto list of "open source" licenses; the script's policy is consistent with this list (with the addition of LGPL / MPL-2.0 in transitive deps for Python import-safety).
+- `pip-audit` (PyPA) — the CVE-checking tool invoked as a subprocess. Optional; the script handles its absence gracefully.

+# Implementation Plan: Manual UX Validation — ASCII-Sketch Workflow (manual_ux_validation_20260608)
+
+> **Test debt note (per the prior track pattern):** This track is **inherently visual + interactive** and is partly manual. The implementation phase (Phase 3) is TDD-friendly — `gui_2.py:3770 render_discussion_entry` has TDD-testable behavior (A1-A7 operations). The design phase (Phase 2) is not TDD — it's ASCII-sketch iteration with the user. The workflow definition phase (Phase 1) is *asking the user 5 questions* — not TDD either.
+>
+> **The phases are NOT equal-effort.** Phase 1 is ~5 min (5 questions). Phase 2 is ~30-60 min (1-3 ASCII-sketch rounds with the user). Phase 3 is the bulk: 1-3 hours of TDD implementation. Phase 4 is ~15 min (docs + next-targets).
+
+---
+
+## Phase 1: Resolve the 5 Open Questions (~5 min)
+
+Focus: get the user's answers to the workflow's 5 open questions (per `docs/reports/ascii_sketch_ux_workflow_20260608.md` §7). Without these answers, Phase 2 cannot start (we don't know which vocabulary, which comparison policy, etc.).
+
+- [ ] **Task 1.1**: Initialize MMA Environment `activate_skill mma-orchestrator`
+- [ ] **Task 1.2**: Pose the 5 open questions to the user (one at a time, with the proposed defaults in `spec.md` §2.1-2.5)
+    - **WHERE**: this conversation (Tier-1 → user → Tier-1 round-trip)
+    - **WHAT**: 5 questions about vocabulary, comparison policy, storage, tooling, frequency
+    - **HOW**: one question per turn; multiple-choice where possible; the spec's defaults are pre-staged so the user can just say "use defaults" for all 5
+    - **SAFETY**: don't lock in a default without explicit user approval. Even if the user says "use defaults," record the choice in the decision log.
+- [ ] **Task 1.3**: Write `decisions.md` capturing the 5 answers
+    - **WHERE**: `conductor/tracks/manual_ux_validation_20260608/decisions.md`
+    - **WHAT**: 5 sections (Q1-Q5) with the user's answer, the rationale, and any caveats
+    - **HOW**: section per question; quote the user verbatim where the answer is non-obvious
+- [ ] **Task 1.4**: Conductor - User Manual Verification "Phase 1: 5 Open Questions Resolved" (Protocol in workflow.md)
+    - Ask the user to confirm the decisions.md captures the answers correctly
+    - Commit decisions.md with git note summarizing the 5 answers
+
+---
+
+## Phase 2: Execute the Workflow on the First Target (~30-60 min)
+
+Focus: produce the locked design contract for the Discussion Hub per-entry panel (`gui_2.py:3770`). The output is `designs/discussion_hub_per_entry_v1.md` (per the spec's Phase 2 deliverable).
+
+- [ ] **Task 2.1**: Establish the boundary (per the spec's §3.2)
+    - **WHERE**: this conversation
+    - **WHAT**: confirm the boundary: inside = one entry, header + body + footer, all 7 A-ops; outside = discussion selector (B6) + discussion-level controls (B1-B11) + thinking-trace widget
+    - **HOW**: post the spec's §3.2 boundary as a checklist; user confirms or adjusts
+    - **SAFETY**: boundary disagreements are normal; if the user wants a different boundary, update the spec's §3.2 *first*, then proceed
+- [ ] **Task 2.2**: Audit the current implementation (so the first draft is grounded)
+    - **WHERE**: `src/gui_2.py:3770 render_discussion_entry` (100+ lines)
+    - **WHAT**: list every widget, every state read, every state write, every interaction
+    - **HOW**: read the function in full; produce a 1-page summary "what the current per-entry panel does" (no judgments, just facts)
+- [ ] **Task 2.3**: ASCII sketch (round 1, Tier-1 first draft)
+    - **WHERE**: this conversation
+    - **WHAT**: first ASCII sketch of the redesigned panel (using the user's chosen vocabulary from Q1)
+    - **HOW**: follow the workflow's Step 3 (per `docs/reports/ascii_sketch_ux_workflow_20260608.md` §1 Step 3); the sketch is *what the panel will look like after the redesign*, not the current state
+    - **SAFETY**: don't try to make it perfect. First drafts are for the user to react to.
+- [ ] **Task 2.4**: User critique → Tier-1 revision (round 2, 3 if needed)
+    - **WHERE**: this conversation
+    - **WHAT**: the user critiques; the Tier-1 revises
+    - **HOW**: 1 round = 1 revision from Tier-1, 1 critique from the user; the workflow caps at 3 rounds before falling back to `MiniMax understand_image`
+- [ ] **Task 2.5**: Lock the design (when the user says "that's it")
+    - **WHERE**: `conductor/tracks/manual_ux_validation_20260608/designs/discussion_hub_per_entry_v1.md`
+    - **WHAT**: 3 parts: (1) the ASCII sketch (the visual); (2) the interaction list (click/hover/drag/keyboard → effect); (3) the state list (collapsed/expanded, edit/read, populated/empty, conditions that trigger them)
+    - **HOW**: copy the locked ASCII into the design doc; enumerate the interactions explicitly (don't say "click does X" without listing what X is); enumerate the states
+- [ ] **Task 2.6**: Conductor - User Manual Verification "Phase 2: Design Contract Locked" (Protocol in workflow.md)
+    - Ask the user to confirm the design contract in `designs/discussion_hub_per_entry_v1.md` is final
+    - Commit the design doc with git note summarizing the locked design + the SSDL principles applied (if any) per spec §2.6
+
+---
+
+## Phase 3: Implement the Design (~1-3 hours, TDD)
+
+Focus: implement the locked design in `src/gui_2.py:3770` per the contract. TDD-style: write tests for the A1-A7 operations, watch them fail, implement, watch them pass.
+
+- [ ] **Task 3.1**: Add the `live_gui` test fixture baseline check
+    - **WHERE**: `tests/conftest.py` (or the appropriate test file)
+    - **WHAT**: verify the existing `live_gui` fixture works (per `docs/guide_testing.md`); the new tests will use it
+    - **HOW**: `uv run pytest tests/test_gui_discussion_entry_smoke.py -k smoke` (or whatever pre-existing smoke test exists)
+    - **SAFETY**: if the live_gui fixture is broken, fix that FIRST before writing new tests (per the pre-flight check pattern in `conductor/workflow.md`)
+- [ ] **Task 3.2**: Write failing tests for A1 (collapse/expand)
+    - **WHERE**: `tests/test_render_discussion_entry_collapse.py` (new)
+    - **WHAT**: test that `gui_2.py:3770 render_discussion_entry` correctly toggles the `entry["collapsed"]` flag when the +/- button is clicked; test that the body is hidden when collapsed and visible when expanded
+    - **HOW**: use `live_gui` fixture + Hook API; render the discussion hub; click the +/- button; assert the body is/isn't visible
+    - **SAFETY**: handle the "defer-not-catch" pattern for `imgui.save_ini_settings_to_memory` per `conductor/workflow.md`'s 2026-06-05 pitfall; use the `_ini_capture_ready` flag
+- [ ] **Task 3.3**: Write failing tests for A2 (edit/read toggle)
+    - **WHERE**: `tests/test_render_discussion_entry_edit_toggle.py` (new)
+    - **WHAT**: test that the [Edit]/[Read] button correctly toggles `entry["read_mode"]`; test that the body shows an `input_text_multiline` when in edit mode, plain text when in read mode
+- [ ] **Task 3.4**: Write failing tests for A3 (role change via combo)
+    - **WHERE**: `tests/test_render_discussion_entry_role.py` (new)
+    - **WHAT**: test that the role combo correctly changes `entry["role"]` when a new role is selected from `app.disc_roles`; test that the role-tinted background updates
+- [ ] **Task 3.5**: Write failing tests for A4 + A5 (insert before / insert after)
+    - **WHERE**: `tests/test_render_discussion_entry_insert.py` (new)
+    - **WHAT**: test that clicking [Ins] creates a new entry above/below; test that the new entry has the default role + empty content
+- [ ] **Task 3.6**: Write failing tests for A6 (delete)
+    - **WHERE**: `tests/test_render_discussion_entry_delete.py` (new)
+    - **WHAT**: test that clicking [Del] removes the entry from `app.disc_entries`; test that the HistoryManager (per `docs/guide_state_lifecycle.md`) captures the deletion in the undo stack
+- [ ] **Task 3.7**: Write failing tests for A7 (branch)
+    - **WHERE**: `tests/test_render_discussion_entry_branch.py` (new)
+    - **WHAT**: test that clicking [Branch] calls `project_manager.branch_discussion` with the current entry as the branch point; test that a new take is created
+- [ ] **Task 3.8**: Run the full A1-A7 test suite; confirm all 7 fail (Red phase)
+    - **WHERE**: shell
+    - **WHAT**: `uv run pytest tests/test_render_discussion_entry_*.py -v`
+    - **HOW**: expect 7 failures (or skips) for the new tests; the old code doesn't match the new design
+    - **SAFETY**: if any test passes for the wrong reason, investigate before proceeding
+- [ ] **Task 3.9**: Implement the redesign in `gui_2.py:3770`
+    - **WHERE**: `src/gui_2.py:3770 render_discussion_entry` (modify; ~100+ lines → ~150-200 lines depending on design)
+    - **WHAT**: implement the locked design from `designs/discussion_hub_per_entry_v1.md`
+    - **HOW**: follow the locked sketch literally; every widget, every state, every interaction should match the contract; if the implementation diverges, update the contract first
+    - **SAFETY**: keep the per-entry thinking-trace widget in its own function (it's already separated per `docs/guide_discussions.md`); don't refactor what isn't in scope
+- [ ] **Task 3.10**: Run the A1-A7 tests; confirm all 7 pass (Green phase)
+    - **WHERE**: shell
+    - **WHAT**: `uv run pytest tests/test_render_discussion_entry_*.py -v`
+    - **HOW**: expect 7 passes; if any fails, debug and fix (do NOT mark task complete with failing tests; do NOT add `@pytest.mark.skip` without explicit user approval)
+- [ ] **Task 3.11**: Run the full test suite to confirm no regressions
+    - **WHERE**: shell
+    - **WHAT**: `uv run pytest tests/ --timeout=60` (small batches of 4 max per workflow.md; the live_gui tests are sensitive)
+    - **HOW**: batch as: (a) unit tests for gui_2.py; (b) live_gui tests; (c) any test that imports the discussion system; run each batch separately
+    - **SAFETY**: per the workflow.md "do not run the full suite" rule; use targeted batches
+- [ ] **Task 3.12**: Verify with `MiniMax understand_image` (per Q2 decision from Phase 1)
+    - **WHERE**: shell + `MiniMax understand_image` tool
+    - **WHAT**: render the actual GUI; take a screenshot of the redesigned per-entry panel; compare the screenshot to the locked ASCII sketch
+    - **HOW**: if Q2 = "always", this is mandatory; if "only on mismatch", this is conditional on Tier-3 reporting a mismatch
+    - **SAFETY**: if the screenshot reveals deltas from the sketch, update the sketch to match the actual implementation (the sketch is a contract, not a wish; if reality differs, fix the sketch first, then the code)
+- [ ] **Task 3.13**: Atomic commit per task pattern
+    - **WHERE**: git
+    - **WHAT**: commit each test file separately (per workflow.md "atomic per-task commits")
+    - **HOW**: `git add tests/test_render_discussion_entry_*.py; git commit -m "test(gui): failing tests for A1-A7 operations on render_discussion_entry"` (one commit per test file or one commit per group of 2 related tests; not a single big commit)
+- [ ] **Task 3.14**: Final commit for the implementation
+    - **WHERE**: git
+    - **WHAT**: commit the modified `src/gui_2.py:3770` + the design doc
+    - **HOW**: `git add src/gui_2.py conductor/tracks/manual_ux_validation_20260608/designs/; git commit -m "feat(gui): implement Discussion Hub per-entry panel redesign per locked ASCII contract"`
+- [ ] **Task 3.15**: Attach git notes per the workflow.md protocol
+    - **WHERE**: git
+    - **WHAT**: for the implementation commit, attach a git note summarizing the 7 A-ops, the 1-3 design rounds, the test count, the MiniMax verification result, and the SSDL principles applied (if any)
+- [ ] **Task 3.16**: Conductor - User Manual Verification "Phase 3: Implementation Complete" (Protocol in workflow.md)
+    - Ask the user to confirm the implementation matches the locked design
+    - Update `state.toml` to mark all Phase 3 tasks complete with the commit SHAs
+
+---
+
+## Phase 4: Document the Pattern + Identify Next Targets (~15 min)
+
+Focus: capture the workflow learnings, update the workflow report with the answered Q1-Q5, and propose the next 5-7 targets.
+
+- [ ] **Task 4.1**: Update `docs/reports/ascii_sketch_ux_workflow_20260608.md`
+    - **WHERE**: the workflow report
+    - **WHAT**: §7 "Open questions for the user" → "Resolved Q1-Q5 (per `decisions.md` of this track)"
+    - **HOW**: replace §7 with the 5 answers; cite `decisions.md`; keep the alternatives in the section as historical record
+- [ ] **Task 4.2**: Write `next_targets.md` (5-7 candidate panels)
+    - **WHERE**: `conductor/tracks/manual_ux_validation_20260608/next_targets.md`
+    - **WHAT**: list 5-7 panels that would benefit from the workflow, in priority order
+    - **HOW**: each entry is: (a) panel name + file:line; (b) why it's a good candidate; (c) estimated design effort; (d) the user-facing operation matrix or A-op equivalent; (e) any SSDL defusing opportunities
+    - **CANDIDATES** (from the workflow report's §1):
+        1. Context Panel file row (`gui_2.py` Files & Media → Files)
+        2. Discussion-level controls (B1-B11) — `gui_2.py:4239 render_discussion_entry_controls`
+        3. MMA spawn-approval modal — `gui_2.py:5163+`
+        4. Vendor State tab (post-Vendor-Capability-Matrix ship) — `gui_2.py` Operations Hub
+        5. Persona editor modal
+        6. Keep Pairs widget (per the UI Polish Phase 2 work) — `gui_2.py:3829`
+        7. Truncate/Compress/Save discussion panel (per the UI Polish Phase 2 work)
+- [ ] **Task 4.3**: Commit the docs + next-targets
+    - **WHERE**: git
+    - **WHAT**: commit the workflow update + next_targets.md
+    - **HOW**: separate commits for clarity
+- [ ] **Task 4.4**: Update `conductor/tracks.md` to mark this track as complete
+    - **WHERE**: `conductor/tracks.md`
+    - **WHAT**: move the track from the "Active" / "Backlog" section to the "Recently Archived" section; add a brief summary
+    - **HOW**: the track is shipped but not yet archived; archive when the user says so or when the next track is specced
+- [ ] **Task 4.5**: Conductor - User Manual Verification "Phase 4: Pattern Documented" (Protocol in workflow.md)
+    - Ask the user to confirm the docs + next_targets capture the work
+    - This is the final user-verification checkpoint for the entire track

+# Track Specification: Manual UX Validation — ASCII-Sketch Workflow (manual_ux_validation_20260608)
+
+**Status:** Active (proposed 2026-06-08)
+**Initialized:** 2026-06-08
+**Owner:** Tier 2 Tech Lead
+**Priority:** Medium (UX improvement; not blocking any other track)
+**Type:** Workflow + first-target redesign
+
+> **Why a new track when manual_ux_validation_20260302 already exists?** The 2026-03-02 track (`conductor/tracks/manual_ux_validation_20260302/`) is a *general* UX review track: slow-mode simulation, layout iteration, animation tuning, popup behavior. It's broad and undifferentiated. This new track is **focused** — it promotes a specific workflow (the ASCII-sketch ideation flow from `docs/reports/ascii_sketch_ux_workflow_20260608.md`) to a real track with a concrete first target (the Discussion Hub per-entry panel at `gui_2.py:3770`). The two tracks complement each other: 20260302 is the broad review; 20260608 is the focused workflow. This new track can reference the older track's "Slow-Mode Observation Harness" as a prerequisite if needed.
+
+---
+
+## 1. Overview
+
+This track establishes a **text-side UX ideation workflow** for Manual Slop GUI changes, using ASCII sketches as the shared visual language between the user and the conductor/agent. The motivation is asymmetry: the user can describe what they want a panel to look like, but the agent can only verify the result via `MiniMax understand_image` on a rendered screenshot — and that path is slow + indirect. ASCII is the *direct* medium: both sides can sketch, critique, and converge in 1-3 rounds, all within a text session.
+
+The workflow is defined in `docs/reports/ascii_sketch_ux_workflow_20260608.md` (340 lines). This track's job is to:
+1. **Resolve the 5 open questions** in the workflow report (vocabulary preference, comparison policy, storage location, tooling, frequency)
+2. **Execute the workflow on the first target** — the per-entry rendering of the Discussion Hub at `src/gui_2.py:3770 render_discussion_entry`
+3. **Lock the design contract** for the first target (ASCII sketch + interaction list + state list)
+4. **Implement the design** as a real change to `src/gui_2.py:3770`, verified by rendering the actual GUI + `MiniMax understand_image` comparison
+5. **Document the pattern** so the workflow can be applied to the next ~6 candidate targets
+
+### 1.1 What this track produces
+
+| Artifact | Purpose |
+|---|---|
+| `spec.md` | This file — track design and scoping. |
+| `plan.md` | 4 phases, 8-12 tasks, TDD-style with 2-5 minute granularity. |
+| `metadata.json` | Structured metadata + verification criteria. |
+| `state.toml` | Per-task tracking + any user-corrections. |
+| `designs/discussion_hub_per_entry_v1.md` | Locked design contract for the first target. |
+| `src/gui_2.py:3770` (modified) | Implemented redesign per the locked design. |
+| `tests/test_render_discussion_entry_*.py` (new) | TDD tests for the implementation. |
+
+### 1.2 Non-Goals
+
+- **Not** replacing ImGui or the existing pixel-based design tools. ASCII is an *addition* alongside the existing design process.
+- **Not** applying the workflow to all ~20 GUI panels in one go. One target (Discussion Hub per-entry), one design, one implementation. The next target is a follow-up track.
+- **Not** a general UX review (that's the 20260302 track). This is the *focused* track for the ASCII-sketch workflow specifically.
+- **Not** changing any non-GUI code. The App/Controller separation per `docs/guide_state_lifecycle.md` keeps this track confined to `src/gui_2.py` and the render-only layer.
+
+---
+
+## 2. The 5 Open Questions (must be resolved before Phase 2)
+
+Per `docs/reports/ascii_sketch_ux_workflow_20260608.md` §1.4 and §5, the workflow has 5 open questions. These are *user decisions*, not Tier-2 decisions. They need to be answered before Phase 2 (executing the workflow on the first target).
+
+### 2.1 Q1: Vocabulary preference
+
+The §2 vocabulary in the report proposes:
+- `[I]` for button, `===>` for flow, `o==>` for conditional flow, `[B]` for begin, `[M]` for modal, `[S]` for screen, `[Q]` for queue, `[N]` for nothing, `--` for separator
+
+Alternatives:
+- **Box-drawing characters** (`┌─┐│└─┘`) — more ASCII-art look, but harder to type in some terminals
+- **Markdown tables** — better for tabular data
+- **Hybrid** — ASCII boxes for layout, tables for tabular content
+- **The proposed vocabulary** as-is
+
+**Default if user doesn't pick:** the proposed vocabulary (it's well-defined, copy-pasteable, works in any terminal).
+
+### 2.2 Q2: Comparison policy (when to verify with MiniMax understand_image)
+
+- **Always** — every locked design gets a screenshot comparison. Slow but thorough.
+- **Proportional** — only when the design uses color or non-ASCII content. Otherwise trust the ASCII.
+- **Only on mismatch** — implementing Tier-3 reports a mismatch; only then verify. Fast but can miss visual bugs.
+- **Never** — trust the implementation. Fastest, but the workflow's main verification step is missing.
+
+**Default if user doesn't pick:** only-on-mismatch (the implementing Tier-3 reports success or flags deltas; conductor decides whether to verify).
+
+### 2.3 Q3: Storage location (where the locked designs live)
+
+- **Track's `spec.md` as an appendix** — keeps designs co-located with the track that produced them
+- **`conductor/designs/`** — central location, designs persist beyond their track's lifetime
+- **`docs/designs/`** — public-designs location, visible in the docs tree
+- **Inline in the conductor/agent session** — the sketch lives in the conversation only
+
+**Default if user doesn't pick:** track's `spec.md` as an appendix (co-located is simplest; can be promoted later).
+
+### 2.4 Q4: Tooling (automation)
+
+- **Manual** — the workflow is purely text; no tooling
+- **Scaffold renderer** — a Python script that turns ASCII into a real ImGui panel scaffold (rough first pass)
+- **ASCII-vs-screenshot diff** — an automated `MiniMax understand_image` call that compares the locked ASCII to a rendered screenshot
+- **Diffable text designs** — design files are version-controlled; conductor diffs previous vs current
+
+**Default if user doesn't pick:** manual (no tooling for v1; revisit if the workflow gets used 3+ times and the manual steps become rote).
+
+### 2.5 Q5: Frequency (when to use the workflow)
+
+- **Every panel change** — overhead ~10 min per change, maximum design rigor
+- **Only new panels** — no overhead for existing panels, but no redesign opportunity
+- **Only on request** — user explicitly says "use the workflow on X"
+- **On track boundary** — every new track that touches `gui_2.py` triggers a workflow round
+
+**Default if user doesn't pick:** only-on-request (the user decides when the workflow earns its overhead).
+
+---
+
+## 2.6 SSDL cross-reference: a different vocabulary for a different purpose
+
+**Important distinction.** The ASCII-sketch workflow report (`docs/reports/ascii_sketch_ux_workflow_20260608.md`) uses a **GUI ASCII vocabulary** — for sketching ImGui panels (buttons, combos, separators, layouts). The SSDL digest (`docs/reports/computational_shapes_ssdl_digest_20260608.md`) uses a **computational shapes vocabulary** — for sketching data flow, control flow, and parallelism in code (codepaths, codecycles, branches, merges, nil sentinels, generational handles).
+
+**They are two different vocabularies for two different purposes.** Conflating them is a likely failure mode:
+- The GUI ASCII vocabulary (the workflow's) is about *what the user sees* (panel layout, widget inventory, state, interactions)
+- The SSDL vocabulary is about *what the code does* (effective codepaths, defusing techniques, data flow)
+
+**When to use which:**
+- **GUI ASCII** for designing the panel (Phase 2 deliverable: `designs/discussion_hub_per_entry_v1.md`)
+- **SSDL** for designing the panel's *internal logic* — the Python code that backs the panel. If the redesign simplifies the per-entry panel by pushing branches into subsystems (per the SSDL digest's §6 "meta-skill"), the SSDL is the right sketch vocabulary for that.
+
+**Concrete example for the first target:** the current `gui_2.py:3770` has an `entry.get("collapsed", False)` check that runs every render frame. This is a branch in user code. Per the SSDL digest's §2.2 "Technique 1: Nil sentinel", a `[N]` defusing approach would push this branch into a subsystem: `entry_view = entry_view_for(entry)` (always returns a valid view, with the collapsed state baked in). The user's render code is then a single straight-line codepath. The SSDL sketch for this internal change looks different from the GUI ASCII sketch for the visible panel.
+
+**Both vocabularies are useful for this track.** Phase 2 produces the GUI ASCII (the design contract for the implementing Tier-3); Phase 3 may produce SSDL sketches as documentation of the internal refactoring decisions.
+
+---
+
+## 3. The First Target: Discussion Hub Per-Entry Panel
+
+### 3.1 Why this target
+
+The per-entry rendering of the Discussion Hub is the **highest-value redesign candidate** because:
+
+1. **It is the user-facing surface that gets interacted with most.** Every AI message and every user message is rendered through this panel. The user looks at it on every turn.
+2. **The user has strong opinions here.** Per the nagent_review track (commit `9cc51ca9`), the user flagged the editable-discussion verdict (PARITY / DIFFERENT FOCUS) and the 3 rounds of corrections indicate the user thinks carefully about this surface.
+3. **The 23-op matrix is the source of truth.** `docs/guide_discussions.md` enumerates the full A1-A7 (per-entry) + B1-B11 (discussion-level) + C1-C5 (undo/redo) operation matrix. The current `gui_2.py:3770 render_discussion_entry` implements a subset. The redesign should explicitly cover the full A1-A7 matrix.
+4. **ImGui layout maps cleanly to ASCII.** Per-entry is a 1-column layout with header + body + footer. Standard ImGui grammar; ASCII captures it well.
+5. **The current implementation is 100+ lines and has accreted state.** Refactoring it benefits from a design contract (not just "preserve existing behavior").
+6. **The SSDL digest's "domain vs systems" lens (§3) and defusing techniques (§2.2) can guide the internal refactoring.** The current `gui_2.py:3770` has 4-5 branches (collapsed, read_mode, role change, ins/del, branch) that all do roughly the same thing with different inputs — exactly the pattern the SSDL digest flags as a "wide codepath" / "effective codepath" candidate. The redesign can either preserve all 4-5 branches *as visible UI affordances* (a 1-N mapping that's correct for UX) OR defuse 1-2 of them (e.g., collapse `collapsed` and `read_mode` into a single `view_state` enum). The user decides.
+
+### 3.2 The boundary for the first target
+
+- **Inside:** one entry, header controls + body + footer, all 7 A-operations (A1 collapse, A2 edit/read toggle, A3 role change, A4 insert before, A5 insert after, A6 delete, A7 branch)
+- **Outside:** the discussion selector (B6) above; the discussion-level controls (B1-B11) below; the per-entry thinking-trace widget (separate, already in its own render function)
+- **State:** expanded, edit mode, AI role, has thinking segments, has timestamp + token usage
+- **Interactions:** click +/- to collapse, click [Edit]/[Read] to toggle mode, click combo to change role, click Ins/Del/Branch buttons
+- **Theme:** default (NERV is opt-in; baseline first)
+
+### 3.3 The expected ASCII sketch (first draft, for the user's critique)
+
+See `plan.md` Phase 2 Task 2.3 for the first draft. The user will critique; we converge in 1-3 rounds.
+
+### 3.4 The design contract (after lock)
+
+Once the user says "that's it," the locked design is captured in `conductor/tracks/manual_ux_validation_20260608/designs/discussion_hub_per_entry_v1.md` with 3 parts:
+1. **The ASCII sketch** (the visual)
+2. **The interaction list** (click/hover/drag/keyboard → effect)
+3. **The state list** (collapsed/expanded, edit/read, populated/empty, conditions that trigger them)
+
+This becomes the implementation contract for `src/gui_2.py:3770`.
+
+---
+
+## 4. The 4 Phases (overview)
+
+| Phase | Name | Deliverable |
+|---|---|---|
+| 1 | Resolve the 5 Open Questions | `decisions.md` capturing the user's choices |
+| 2 | Execute Workflow on First Target | `designs/discussion_hub_per_entry_v1.md` (locked design contract) |
+| 3 | Implement the Design | `src/gui_2.py:3770` modified per the contract; TDD tests pass |
+| 4 | Document the Pattern | Update `docs/reports/ascii_sketch_ux_workflow_20260608.md` with the answered Q1-Q5; add 5-7 next-target candidates to a `next_targets.md` |
+
+The full plan with 2-5 minute TDD steps is in `plan.md`.
+
+---
+
+## 5. Architectural Reference
+
+- **ASCII-sketch workflow report:** `docs/reports/ascii_sketch_ux_workflow_20260608.md` (340 lines; the workflow's design + 5 open questions)
+- **SSDL digest (computational shapes vocabulary):** `docs/reports/computational_shapes_ssdl_digest_20260608.md` (504 lines; 6 primitives + 7 modifiers + 5 defusing techniques + "domain vs systems" lens; a different vocabulary for the *internal logic* of the redesigned panel — see §2.6 for the GUI-ASCII vs SSDL distinction)
+- **Discussion system source of truth:** `docs/guide_discussions.md` (353 lines; 23-op matrix A1-A7 + B1-B11 + C1-C5)
+- **Discussion system state lifecycle:** `docs/guide_state_lifecycle.md` (375 lines; UISnapshot + HistoryManager + 4-thread access pattern)
+- **GUI App class + hot-reload:** `docs/guide_gui_2.md` (477 lines; module-level render functions for state-preserving hot-reload)
+- **Current implementation:** `src/gui_2.py:3770 render_discussion_entry` (100+ lines; the file to be modified)
+- **Existing UX review track (complementary):** `conductor/tracks/manual_ux_validation_20260302/` (general UX review; slow-mode sim + layout iteration + animation tuning + popup behavior)
+
+### 5.1 What this track inherits from manual_ux_validation_20260302
+
+- The "Slow-Mode Observation Harness" (`simulation/ux_observation_sim.py`) is a useful *verification* tool: after implementing the design, run the slow-mode sim to watch the redesigned entry panel in action
+- The "Auto-Close Popups" idea is a related UX concern; if the redesigned entry panel introduces new popups, those should be subject to the 20260302 auto-close policy
+- The "Layout Finalization" work in 20260302 is a precedent: the user has approved the practice of "rapidly apply changes requested by the user and re-render"
+
+### 5.2 What this track does NOT do from manual_ux_validation_20260302
+
+- The general layout/structure iteration (Tabs vs Panels vs Collapsing Headers) is the 20260302 track's domain
+- Animation tuning (blinking frequencies, color vectors) is the 20260302 track's domain
+- This track is *focused* on the ASCII-sketch workflow + first target; the 20260302 track is the broad review

+
+## 7. Scope Boundaries
+
+### In Scope
+
+- Resolve the 5 open questions (Phase 1)
+- Lock a design contract for the Discussion Hub per-entry panel (Phase 2)
+- Implement the design in `src/gui_2.py:3770` (Phase 3)
+- Add TDD tests (Phase 3)
+- Document the pattern; propose the next 5-7 targets (Phase 4)
+
+### Out of Scope
+
+- Applying the workflow to all GUI panels (that's a follow-up track per panel)
+- Changing the underlying Discussion data model (that's `data_structure_strengthening_20260606` + the public_api_migration_20260606 follow-up)
+- Changing the per-entry thinking-trace widget (separate render function; not in scope for the first target)
+- Animation tuning (general UX review; 20260302 track)
+- Popup auto-close (general UX review; 20260302 track)
+
+### Known Trade-offs (called out in the workflow report)
+
+- **ASCII is a proxy, not a substitute.** Some ImGui features (custom shaders, NERV CRT effects, multi-viewport layouts) don't translate. The workflow falls back to `MiniMax understand_image` for those cases.
+- **The workflow is not faster than just editing `gui_2.py` directly.** It adds ~10 min overhead per panel. The value is *design rigor* (the user can critique the sketch before code is written), not speed. The user decides when the overhead is worth it (Q5).
+- **The first target may not be the highest-value redesign candidate.** It's a *good* candidate (high interaction, user has opinions, source of truth is documented), but the user may prefer a different first target. The 7 candidates in `docs/reports/ascii_sketch_ux_workflow_20260608.md` §1 are all valid alternatives.

 ### 3.3 The 3-Layer Security Model
 
+**Important (added 2026-06-08):** the 3-layer security model (Allowlist Construction → Path Validation → Resolution Gate, per `docs/guide_mcp_client.md`) is not just refactored — it is the **contract** between `MCPController` and the sub-MCPs. Sub-MCPs receive a *pre-validated* `pathlib.Path` from `_resolve_and_check` and trust it. They do *not* re-validate. This is the security invariant that the refactor must preserve: the 3 layers run *before* the sub-MCP's `invoke()` is called, and the sub-MCP treats the path as already-allowed.
+
+Concrete consequences:
+- `_resolve_and_check` is called by `MCPController.dispatch` *before* the sub-MCP's `invoke()`. The sub-MCP sees a `Result[Path]` and the `data` field is either a real `Path` (allowed) or a `NilPath` (denied).
+- Sub-MCPs that take a `path: str` parameter call `_resolve_and_check` themselves in their `invoke()` (or, if the path is already validated, they skip it). The current `src/mcp_client.py:_resolve_and_check` is moved to `src/mcp_client_security.py` unchanged.
+- The 3-layer pattern is *not* weakened by the refactor. The `_is_allowed` check (Layer 1) still uses `_ALLOWED_BASE_DIRS`; the resolution (Layer 3) still uses `Path.resolve()`. The refactor is a *structural* change, not a *security* change.

The update should add a §"Sub-MCP Architecture" section describing the new layout, link the `SubMCP.list_tool_schemas()` pattern to `docs/guide_mcp_client.md §"3-Layer Security Model"`, and cross-link `docs/guide_context_aggregation.md` (the new pipeline guide, which `mcp_file_io.py` consumers use) and `docs/guide_state_lifecycle.md` (which documents the `App.__getattr__`/`__setattr__` state delegation that sub-MCPs must respect).

+
+## 5.5 Opencode-stable swap (non-destructive development + quality-gated rollout)
+
+**Why this section exists.** The current `scripts/mcp_server.py` (and the `mcp_client.dispatch` it wraps) is consumed by **opencode clients** via the MCP protocol. opencode is the AI agent tool that uses Manual Slop's tool surface. The new sub-MCP architecture MUST be developed in a way that does not break opencode's existing usage during development, AND the actual swap (the new dispatch becoming the default in `sloppy.py`'s controller) MUST be gated on a stability verification.
+
+**Non-destructive development principle.** Throughout Phases 1-6, the existing `mcp_client.py` continues to work exactly as it does today. The new sub-MCPs, the new controller, the new security module are all added AS NEW FILES (or alongside the existing code in `mcp_client.py`). The legacy code path remains the default. opencode clients see zero behavioral change during Phases 1-6.
+
+**The swap mechanism.** `sloppy.py` (the entry point) and `app_controller.py` (the controller init) introduce a single configuration flag:
+
+```python
+# In sloppy.py / app_controller.py
+MCP_USE_NEW_DISPATCH: bool = False  # default during Phases 1-6; flipped to True after Phase 7 verification
+```
+
+When `MCP_USE_NEW_DISPATCH=False` (default during development):
+- The legacy shim is the dispatch path (Phase 2's behavior; preserved as the safe default)
+- All existing opencode workflows work unchanged
+- The new sub-MCPs exist but are NOT in the dispatch path; they can be developed and unit-tested in isolation
+
+When `MCP_USE_NEW_DISPATCH=True` (Phase 7's flip, gated on verification):
+- The new controller (`MCPController`) is the dispatch path
+- The legacy shim is still present (for any direct imports) but no longer called by the entry point
+- opencode clients connect via the MCP server, which now uses the new dispatch
+- All 45+ tools must work identically via the new path (verified by the opencode stability check)
+
+**The verification (opencode stability check).** Before Phase 7 flips the default to `MCP_USE_NEW_DISPATCH=True`:
+
+1. **Unit tests pass**: the per-sub-MCP unit tests + the controller tests + the legacy-shim regression tests all pass.
+2. **Existing test files pass unchanged**: `test_mcp_client_beads.py`, `test_mcp_config.py`, `test_mcp_perf_tool.py`, `test_mcp_ts_integration.py` pass without modification (they use the legacy shim, which delegates correctly).
+3. **Opencode integration test**: a manual or automated test where opencode connects to the MCP server (using `MCP_USE_NEW_DISPATCH=True`), lists the available tools, and invokes 5-10 representative tools (e.g., `read_file`, `list_directory`, `py_get_skeleton`, `py_find_usages`, `web_search`, `derive_code_path`). The results must match the expected outputs.
+4. **Soak test**: the opencode integration test runs cleanly for 5+ consecutive sessions over 1+ day without regressions, errors, or performance degradation.
+
+**When the verification passes, the track ships with `MCP_USE_NEW_DISPATCH=True` as the default in `sloppy.py`.** When it doesn't (e.g., a sub-MCP has a regression, or a new sub-MCP's tool doesn't work via opencode), the default stays `False` until the issues are resolved.
+
+**The flag is the boundary.** It is the single point where the new system becomes the default. During Phases 1-6, the flag is `False` and opencode sees no change. After Phase 7, the flag is `True` (gated on verification). Future tracks can extend either path without re-architecting.
+
+## 5.6 Compatibility surface preserved during development
+
+To make the non-destructive development principle concrete, here is the public surface that MUST keep working throughout the track (i.e., across all 7 phases):
+
+| Consumer | What it uses | How it keeps working |
+|----------|--------------|----------------------|
+| `scripts/mcp_server.py` | `mcp_client.dispatch("tool_name", args)` and `mcp_client.async_dispatch(...)` | These functions exist in the legacy shim throughout Phases 1-6; in Phase 7 they delegate to the new controller (when the flag is True) or stay as-is (when the flag is False). |
+| `src/app_controller.py:61` | `mcp_client.py_get_symbol_info(...)` (a direct function call) | This function is in `mcp_client_legacy.py` and re-exported from `mcp_client.py` from Phase 2 onward. Unchanged for opencode. |
+| opencode (via MCP protocol) | The 45+ tool names; the JSON tool-call format; the response shape | The legacy shim preserves all 45+ tool names + signatures + return shapes (string). opencode sees no change until the flag is flipped in Phase 7. |
+| The 4 existing test files | `mcp_client.<func_name>(...)` and the dispatch result | Legacy shim re-exports; tests pass unchanged. |

The Phase 7 update for this track should add a §"Sub-MCP Architecture" section.
+- `docs/guide_context_aggregation.md` — added 2026-06-08. The `aggregate.py:142 build_file_items` function consumes the `FileItem` list and is the *upstream* consumer of `mcp_file_io.py`. The sub-MCP refactor must preserve the `FileItem` schema documented in §"The FileItem Schema (Full)".

The `App.__getattr__`/`__setattr__` state delegation (per `gui_2.py:666-675`) and the `UISnapshot` capture/restore are the *correctness* the sub-MCP refactor must preserve; sub-MCP tools are called from the `App` instance and any state mutation must go through the Controller.

+- **Domain tags:** APP = Application domain, MT = Meta-Tooling domain, BOTH.
+
+---
+
+| # | nagent Principle (verbatim summary) | nagent Mechanism | Manual Slop Equivalent | Verdict | Domain | Action |
+|---|---|---|---|---|---|---|
+| 1 | Durable work, disposable workers. The agent is not the thing; the data is the thing. | `bin/nagent` 700-line single-file loop, conversation is a text file | MMA workers are real subprocesses with Context Amnesia; **Application AI is long-lived by design** | **PARTIAL** | BOTH | Future-track: stateless `LLMClient` class (§15.4) |
+| 2 | Text in, text out. File in, text out is the smallest useful primitive. | `bin/nagent-llm-text` + `bin/helpers/nagent_llm.py` (4 providers) | `src/ai_client.py:send(...) -> str` (5 providers) | **PARITY** | BOTH | None |
+| 3 | Conversations are editable state. The conversation file is not chat history; it is working state. | `bin/nagent` exposes `--save/load/edit/summarize`; text files are user-editable (vim/cat/diff/cp the raw transcript) | Discussion Takes + branching + per-entry edit (A1-A7 in report §3) + discussion-level CRUD (B1-B11) + role management (B5) + UI snapshot undo/redo (C1-C5) | **PARITY (DIFFERENT FOCUS)** — Manual Slop edits abstracted typed entries (`disc_entries` is a `list[dict]` with role + content + ts + thinking_segments + usage). Both have comprehensive editing; Manual Slop's is more granular at the entry layer, nagent's is deeper at the raw-transcript layer. | APP | Future-track: optional raw-transcript persistence per Take (Candidate 10) |
+| 4 | Visible output protocol. Teach the model an output format; use a visible, parseable protocol. | `TAG_PATTERNS` regex list; `parse_response` strict; `MAX_FORMAT_RETRIES = 3` | Provider-native function calling (Gemini, Anthropic, etc.) | **ARCHITECTURAL DIFFERENCE** — Application's choice is correct (parallel tool calls, JSON mode) | BOTH | Future-track: intent-based DSL for Meta-Tooling calls |
+| 5 | The loop. Append, call, parse, act, append, repeat. | `bin/nagent:run_agent_loop()` 50 lines, single `while True` | Three parallel loops: `ai_client._send_*` (LLM), `ConductorEngine.run` (MMA), `WorkflowSimulator.run_discussion_turn_async` (App) | **PARITY** | BOTH | (Low priority) Future-track: extract a single `src/llm_loop.py:run_loop` |
+| 6 | Per-file memory. Each file gets its own persistent local memory. | `file_id_for_path` (st_dev:st_ino); `conversations/file-index-{pid}.json`; `nagent-file-edit` per-file subprocess | `FileItem` (path + view_mode + ast_mask + custom_slices); `ContextPreset` (saved set of FileItems); Structural File Editor | **PARITY (DIFFERENT KIND)** — Manual Slop's is *curation memory* (rich); nagent's is *conversation log memory* (plain text). Both real, both per-file, different optimization. | APP | Future-track: thin "last-investigation" log per file (Meta-Tooling-friendly) |
+| 7 | Repository history as data. Turn git history into editing context. | `git_file_history` + `summarize_new_file_commits` + `coedited_file_rows` + `format_file_history` | `_reread_file_items` (mtime-based, diff injection); git-linked discussion tracking in GUI; **no historical-context injection** | **PARTIAL** — diff injection is similar; historical-context injection is missing | APP | Future-track: `src/git_history.py` mirroring nagent's `file_edit_history_and_summary_block` |
+| 8 | Historical coupling & artifact neighborhoods. Files that change together are hints. | `coedited_file_rows` labels high/medium/low co-edit rate; guidance text "Use these files as hints. Do not edit unless the user request or evidence requires it." | None (closest: `py_get_hierarchy` is structural not historical) | **GAP** | APP | Future-track: `py_coedited_files` + `ts_c_coedited_files` MCP tools |
+| 9 | Disposable sub-conversations. Exploration creates noise; spawn disposable workers. | `<nagent-conversation>` tag spawns `nagent --invocation delegated` as subprocess; isolated conversation file; recursive token rollup | MMA Tier 3/4 workers (real subprocesses); **1:1 main discussion has no sub-conversation mechanism** | **PARITY for MMA; GAP for 1:1 discussions** | APP (and MT) | **USER-FLAGGED WANT**: Future-track `src/sub_conversation.py:SubConversationRunner` for 1:1 investigations |
+| 10 | Controlled writes. A loop that writes files needs explicit boundaries. Not a sandbox; just conventions. | `validate_write_path`: main mode → tmpdir only; file-edit mode → target or segments; rejected writes append `<nagent-write-result status="error">` | `mcp_client._is_allowed` (3-layer: allowlist + path validation + resolution gate); `run_powershell` requires GUI modal approval; PowerShell-only by default; 60s timeout + `taskkill` cleanup; optional Tier 4 QA | **PARITY+ (Manual Slop stronger)** — 3-layer security + HITL + sandbox is dramatically stricter than nagent's tmpdir check | APP (and MT) | None — current design is right |
+| 11 | Large files as explicit artifacts. Split, edit segments, patch. | `nagent-file-split` (11 langs, regex + line counts + brace/JSON/XML depth); `nagent-file-patch` (strict hash validation); `nagent-file-summarize` (per-segment + retry); 32 KB default; index.json with `source_path`, `sourcesha256`, `segments[]` | `aggregate.py:build_file_items` + `py_get_skeleton` (tree-sitter) + `ts_c_*_get_skeleton` (tree-sitter); `set_file_slice` / `edit_file` (mtime validation, not hash); `run_subagent_summarization` (in-process, no retry); `RAGEngine._chunk_code` (mtime-based, ChromaDB) | **PARITY (DIFFERENT MECHANISM)** — both have the insight; nagent uses per-language scoring functions + subprocess isolation + hash validation; Manual Slop uses tree-sitter + in-process + mtime validation | BOTH | Future-track: explicit `src/split_lib.py` + `src/patch_lib.py` mirroring nagent's design, with hash validation |
+| 12 | Tool discovery. Tool capability should be explicit data. | `collect_bin_tool_descriptions` runs each `bin/* --description`; auto-builds "Available tools:" block for initial context | None (45 tools in `mcp_client.py:dispatch` if/elif chain) | **GAP** — nagent's pattern is genuinely better; current dispatch is fine but not extensible | BOTH (especially MT) | Future-track: subsumed by `mcp_architecture_refactor_20260606` (sub-MCPs as self-describing modules) |
+| 13 | Differences from frameworks. The reframing table: memory→editable artifact, agent→temporary transformation function, context→explicit input data. | The philosophical frame | The applicable reframings: editable UI state, curated per-file memory, git history as data | **N/A** | BOTH | (Lens, not action) |
+| 14 | Build your own. 12-step buildable list. | The reference | Manual Slop has all 12, in different files, at different scale | **PARITY** | BOTH | (Checklist) |

+
+See `report.md §15` for full details. Quick reference:
+
+| # | Pitfall | Domain | Future-track | User flag? |
+|---|---|---|---|---|
+| 1 | No structured output protocol in Application AI (opaque function calling) | BOTH | Intent-based DSL for Meta-Tooling | Implicit ("intent based DSL to help with discovery") |
+| 2 | Provider-specific history in process globals (`_anthropic_history`, `_deepseek_history`, etc.) | APP | Stateless `LLMClient` class | No |
+| 3 | RAG is not "history as data" (fuzzy, not auditable) | APP | RAG pre-staging sub-conversation | **Yes** ("Would be cool to have a sub agent maybe prepare a rag chunks before I use them in a run") |
+| 4 | AI client is a stateful singleton with module-level globals (2,685-line file) | APP | Stateless `LLMClient` class (same as #2) | No |
+| 5 | No non-MMA disposable sub-conversations | APP (and MT) | `src/sub_conversation.py:SubConversationRunner` | **Yes** ("I probably want to add that for just 1:1 discussions where I use a sub-agent manually for specific points") |
+| 6 | Hard-coded tool discovery (45-tool if/elif chain) | BOTH | Subsumed by `mcp_architecture_refactor_20260606` | Implicit ("intent based DSL to help with discovery") |
+
+### Pitfalls removed by user-corrections
+
+- **(removed)** "Conversation state is buried in module-level globals" — overstated. Manual Slop has editable UI state (Takes, UISnapshot, ContextPreset); the lack of editable raw transcripts is a *different* design choice, not a gap. See `report.md §3`.
+- **(removed)** "No per-file memory" — overstated. Manual Slop *does* have per-file memory in the curation dimension (FileItem + ContextPreset + Fuzzy Anchors); what's missing is nagent's conversation-log dimension, which is a *different* optimization. See `report.md §6`.
+
+---
+
+## Future-track candidates — priority list
+
+Ordered by user signal + implementation cost:
+
+1. **`src/sub_conversation.py:SubConversationRunner`** — user-flagged as a want. Extract MMA's `mma_exec.py` pattern into a reusable App-callable class. Useful for 1:1 investigations. **High priority.** (Pitfall #5)
+
+2. **RAG pre-staging via sub-conversation** — user-flagged as a want. A sub-agent pre-builds the RAG index for a planned run; the chunks become the discussion's starting memory. **High priority.** (Pitfall #3)
+
+3. **Stateless `LLMClient` class** — would unify Pitfall #2 and #4. Backwards-compatible with `ai_client.send()`. ~2-3 phases of careful refactor. **Medium priority.**
+
+4. **Intent-based DSL for Meta-Tooling tool calls** — user-noted as a want ("no where near that ideation yet"). **Low priority, research spike.**
+
+5. **Self-describing MCP tools (nagent §12 pattern)** — subsumed by `mcp_architecture_refactor_20260606`. **Low priority on its own.**
+
+6. **`src/git_history.py` for nagent §7 pattern** — historical context injection. **Medium priority, but only after #1-#2 are done.**
+
+7. **Per-file conversation log (nagent §6 conversation dimension)** — Meta-Tooling-friendly addition. **Low priority.**
+
+8. **`py_coedited_files` / `ts_c_coedited_files` MCP tools (nagent §8)** — small, contained. **Low priority.**
+
+9. **Explicit `src/split_lib.py` + `src/patch_lib.py` (nagent §11)** — only needed if very-large-file scenarios emerge. **Defer until needed.**
+
+10. **Optional raw-transcript persistence per Take (nagent §3 conversation dimension)** — niche. **Low priority.**

+**Date:** 2026-06-08
+**Source:** nagent v1.0.0 deep-dive review (see `report.md`)
+
+This document is the bridge from "what nagent teaches us" to "what Manual Slop should do about it." Each candidate is a *future* conductor track (not this one). The candidates are *not* committed — they emerge from the analysis but each is a separate scoping exercise.
+
+**For an actionable, code-grounded read of these candidates** (with the "what to do today, not just the future track" framing), see `nagent_takeaways_20260608.md` — it maps each candidate to specific patterns, design constraints, and small UX wins that don't need a new track.
+
+---
+
+## Decision-making framework
+
+For each candidate:
+
+- **Why it matters** — what pitfall or capability gap does it address?
+- **What it would do** — concrete description
+- **Where it would live** — Application or Meta-Tooling
+- **Dependency on existing tracks** — is anything already on the board?
+- **Effort estimate** — small / medium / large
+- **User signal** — has the user expressed want/don't-want/neutral?
+- **Recommended priority** — high / medium / low
+
+The candidates are listed in priority order, which factors user signal heaviest (the user is the product owner for the Application; the analysis is just a reference).
+
+---
+
+## Candidate 1: `src/sub_conversation.py:SubConversationRunner`
+
+**User signal:** **EXPLICIT WANT** ("I probably want to add that for just 1:1 discussions where I use a sub-agent manually for specific points.")
+
+**Why it matters.** nagent's §9 pattern (disposable sub-conversations via `<nagent-conversation>`) is the cleanest way to handle "investigate this without polluting the main discussion." Manual Slop has it for MMA (`mma_exec.py` is a real subprocess) but not for 1:1 discussions. The user is asking for this.

+**What it would do.** A `SubConversationRunner` class that the App can call during a 1:1 discussion:
+- `await runner.spawn(prompt: str, *, allowed_tools: list[str] = None, system_prompt: str = None) -> SubConversationResult`
+- The runner spawns a fresh Python process (reusing the MMA pattern: `mma_exec.py` template with `--invocation user`, `--parent-conversation <active_discussion_id>`, isolated `~/.manual_slop/sub_conversations/<name>`)
+- The sub-process runs to completion (or times out)
+- Result returns: a concise artifact (the sub-agent's `<response>` block) + token usage + exit code
+- The App inserts the result into the active discussion as a "User" role entry (so the parent LLM sees it on the next turn)
+- Cleanup: sub-conversation folder is auto-archived after 7 days (consistent with `log_pruner.py`)
+
+**Where it lives.** Application. Possibly Meta-Tooling too (the `scripts/` directory could use the same primitive).
+
+**Depends on.** None directly. Could leverage MMA's `mma_exec.py` as a starting template. The `public_api_migration_20260606` follow-up track is unrelated.
+
+**Effort.** **Medium.** 2-3 phases: (1) extract reusable subprocess skeleton from MMA, (2) add 1:1-specific context injection, (3) add GUI controls ("Investigate…" button, optional command-palette command).
+
+**Recommended priority.** **HIGH** — user-flagged.
+
+---
+
+## Candidate 2: RAG pre-staging via sub-conversation
+
+**User signal:** **EXPLICIT WANT** ("Would be cool to have a sub agent maybe prepare a rag chunks before I use them in a run.")
+
+**Why it matters.** Manual Slop's RAG (`src/rag_engine.py`) indexes files on the fly at discussion start. For large projects, indexing can take 30+ seconds (per `tests/test_rag_phase4_stress.py`). The user wants a "prep" workflow: before starting a long discussion, fire off a sub-conversation that pre-indexes everything, so the discussion starts instantly.
+
+This is also consistent with nagent's "data preparation is an explicit, visible step" philosophy (§1, §7). The RAG chunks are artifacts; preparing them is a transformation; the transformation can be a sub-conversation.
+
+**What it would do.** A "Pre-stage RAG" command in the GUI (or in `commands.py`):
+- Spawns a sub-conversation with the prompt: "Index all files in [project] for RAG. Use the index_file tool on every file in the context. Report top-K queries at the end."
+- The sub-conversation runs `rag_engine.index_file()` on each tracked file (uses the same `ChromaDB` backend, with mtime-based invalidation)
+- Returns a concise summary: "Indexed N files. Top-K for 'execution clutch': [file1, file2, file3]."
+- The main discussion starts with the index already warm; `RAGEngine.search()` is fast
+
+**Where it lives.** Application. The sub-conversation runner is the same primitive as Candidate 1; the staging logic is `RAGEngine` integration.
+
+**Depends on.** Candidate 1 (sub-conversation runner). Could be done as a feature within Candidate 1's track.
+
+**Effort.** **Small to medium.** The sub-conversation runner is the heavy lift (Candidate 1). The RAG-staging prompt is ~30 lines.
+
+**Recommended priority.** **HIGH** — user-flagged; cheap given Candidate 1.
+
+---
+
+## Candidate 3: Stateless `LLMClient` class
+
+**Why it matters.** `src/ai_client.py` is 2,685 lines of stateful singleton with module-level globals for every provider's history. nagent's `bin/helpers/nagent_llm.py` is 300 lines of stateless dispatch. A refactor toward a stateless `LLMClient(provider, model, conversation)` class would:
+
+- Make `ai_client` parseable (no implicit state to track)
+- Make tests deterministic (each test gets a fresh client)
+- Enable conversation save/load (the `Conversation` object is the transcript)
+- Enable provider switching without losing history
+
+This is a *big* refactor but a high-leverage one. Pitfalls #2 and #4 are both solved.
+
+**What it would do.** A new `src/llm_client.py`:
+```python
+@dataclass
+class Conversation:
+    messages: list[Message]  # role + content + tool_calls + tool_results
+    metadata: dict
+    def to_dict(self) -> dict: ...
+    def from_dict(data: dict) -> Conversation: ...
+    def save(path: Path) -> None: ...
+    def load(path: Path) -> Conversation: ...
+
+class LLMClient:
+    def __init__(self, provider: str, model: str, api_key: str = None): ...
+    def send(self, conversation: Conversation, *, tools: list[Tool] = None) -> Conversation: ...
+    def stream_send(self, conversation: Conversation, *, tools: list[Tool] = None) -> Iterator[Event]: ...
+```
+
+Backwards-compat: `ai_client.send(...)` becomes a thin wrapper that constructs a default `Conversation` from the current state and calls the new class.
+
+**Where it lives.** Application (the AI client is the Application's main AI entry point).
+
+**Depends on.** The `data_oriented_error_handling_20260606` track is independent but related — both push toward the data-oriented principles. The `public_api_migration_20260606` follow-up track would benefit from the new `Conversation` class.
+
+**Effort.** **Large.** 3-5 phases: (1) introduce `Conversation` dataclass, (2) per-provider `LLMClient.send`, (3) migration of existing `ai_client.send` callers, (4) deprecate module-level globals, (5) remove. ~2000+ lines of refactor.
+
+**Recommended priority.** **MEDIUM.** High value, but the existing stateful singleton works. Defer until a concrete Application need forces it (e.g., the user wanting to save/replay conversations).
+
+---
+
+## Candidate 4: Intent-based DSL for Meta-Tooling tool calls
+
+**User signal:** **EXPLICIT WANT** ("The tool use is kinda upfront, I want to add an intent based dsl to help with 'discovery' or combinatorics but no where near that ideation yet.")
+
+**Why it matters.** nagent's §4 regex-tag protocol is more debuggable than Manual Slop's function-calling. The Meta-Tooling (the external agents that build the Application) could benefit from a more compact, inspectable tool-call format. The existing JSON function-calling format forces the user to read verbose `{"name": "...", "args": {...}}` blobs.
+
+**What it would do.** An intent-based DSL that the Meta-Tooling can use in its own work. Examples (per the user's "discovery" or "combinatorics" hint):
+- `<read src/foo.py:MyClass.method>` — intent: read this symbol
+- `<search "execution clutch">` — intent: semantic search the workspace
+- `<edit src/foo.py:42-50:new code>` — intent: surgical line-range edit
+- `<test tests/test_foo.py::test_bar>` — intent: run a specific test
+- `<discover what calls X>` — intent: dependency trace
+
+These are read by the external agent (Gemini CLI, OpenCode), not by Manual Slop's Application AI. The Application's function-calling format stays the same (correct for its domain).
+
+**Where it lives.** Meta-Tooling. Documented in `docs/`; taught via the conductor convention; the external agent emits the DSL, the bridge script (`cli_tool_bridge.py`) translates to actual `mcp_client.py` tool calls.
+
+**Depends on.** None directly. The `mcp_architecture_refactor_20260606` may produce tools that are easier to call via DSL (atomic, composable).
+
+**Effort.** **Research spike, not implementation.** The user said "no where near that ideation yet." This is a design exercise, not a code change.
+
+**Recommended priority.** **LOW** — user explicitly deferred.
+
+---
+
+## Candidate 5: Self-describing MCP tools (nagent §12 pattern)
+
+**Why it matters.** Manual Slop's 45 MCP tools are dispatched by a flat if/elif in `mcp_client.py:dispatch`. Adding a tool requires edits in 4 places (dispatch, security allowlist, capability declaration, tests). nagent's `--description` self-describing executable pattern is more extensible: drop an executable, it auto-appears.
+
+**What it would do.** Each sub-MCP (or each tool) emits a `--description` block on `--help`. The `dispatch` function introspects via `mcp_client.get_tool_schemas()` and includes the descriptions in the AI's initial context automatically.
+
+**Where it lives.** Application (the dispatch layer). The Meta-Tooling already has self-describing (via `claude_tool_bridge.py`); this is the Application-side equivalent.
+
+**Depends on.** The `mcp_architecture_refactor_20260606` is the natural place — the sub-MCPs would each be self-describing modules.
+
+**Effort.** **Medium** (subsumed by mcp_architecture_refactor_20260606). Not a separate track.
+
+**Recommended priority.** **LOW** — subsumed.
+
+---
+
+## Candidate 6: `src/git_history.py` (nagent §7 pattern)
+
+**Why it matters.** Manual Slop's `_reread_file_items` does current-content diff injection. nagent's `file_edit_history_and_summary_block` does *historical* content injection: `git log --follow <file>` per file, LLM-summarized, plus co-edit neighborhood. For "explain this file" questions, the LLM is meeting the file fresh — git history would give it crucial context (who touched it last, why, what's nearby).
+
+**What it would do.** A `src/git_history.py:file_edit_history_and_summary_block(file_path, repo_root, provider, model, config_path, previous_initial_context=None) -> str` that:
+- Calls `git log --follow --max-count=50 --date=short --format=...` per file
+- Counts co-edited files per commit
+- LLM-summarizes new commits (with cache for unchanged history)
+- Renders a `{file-history}` block with editors, step-by-step, co-edited files, summarized commits
+- Called from `aggregate.py:run` at discussion start, after the file is added to context
+
+**Where it lives.** Application (it's part of the AI's initial context).
+
+**Depends on.** None directly. The `data_oriented_error_handling_20260606` is independent. The `rag_engine.py` already has a `sourcesha256` field and mtime-based invalidation — the same pattern.
+
+**Effort.** **Medium.** 2 phases: (1) git history + co-edit, (2) LLM summarization with cache. ~300-500 lines.
+
+**Recommended priority.** **MEDIUM** — high value, but only after Candidates 1-2 are done.
+
+---
+
+## Candidate 7: Per-file conversation log (nagent §6 conversation dimension)
+
+**Why it matters.** Manual Slop's per-file memory is the *curation* kind. nagent's is the *conversation log* kind. The user has the curation already; the conversation log is missing. The user's correction made this clear: the two are *different optimizations*, not equivalent.
+
+**What it would do.** A thin `~/.manual_slop/per_file/<file_id>.md` per file (file_id by `st_dev:st_ino` for stability across renames, like nagent). Updated each time a discussion references the file. Format:
+```markdown
+# src/foo.py (file_id: 12345:67890)
+Last referenced: 2026-06-08T12:34:56 (Discussion: "refactor auth")
+
+## 2026-06-08T12:34:56 - "how does the validation work?"
+AI response: ...
+(User) followup: "what about edge cases?"
+
+## 2026-06-05T... - "explain the parser"
+AI response: ...
+```
+
+When the user opens a new discussion with the file in context, the per-file log is injected as a `{per-file-history}` block.
+
+**Where it lives.** Application (the per-file log is the App's memory). The Meta-Tooling doesn't need this — sub-agent invocations are already short-lived.
+
+**Depends on.** None. Could be added in a small follow-up to Candidate 3 (the `Conversation` object becomes the per-file log).
+
+**Effort.** **Small** if done as a thin layer on top of the `Conversation` class. **Medium** if done before Candidate 3 (no `Conversation` object to leverage).
+
+**Recommended priority.** **LOW** — niche, niche feature.
+
+---
+
+## Candidate 8: `py_coedited_files` / `ts_c_coedited_files` MCP tools (nagent §8)
+
+**Why it matters.** nagent's `coedited_file_rows` produces a "files that historically co-edit with this file" table. Manual Slop has `py_get_hierarchy` (subclass scan) but no historical co-edit tool. Useful for "if I edit this file, what should I also look at?".
+
+**What it would do.** Two new MCP tools:
+- `py_coedited_files(path: str) -> list[{path, commits_together, likelihood}]` — runs `git log --follow <path>`, counts files in each commit, labels high/medium/low
+- `ts_c_coedited_files(path: str) -> list[{path, commits_together, likelihood}]` — same, for C/C++
+
+Returns a table. Used in the initial context as `{file-neighborhood}`.
+
+**Where it lives.** Application (initial context injection).
+
+**Depends on.** None. Small, contained.
+
+**Effort.** **Small.** ~200 lines + tests. The git-log is already in `aggregate.py`; this is a new tool that uses the same primitives.
+
+**Recommended priority.** **LOW** — small but niche. Worth bundling with Candidate 6 if that gets done.
+
+---
+
+## Candidate 9: Explicit `src/split_lib.py` + `src/patch_lib.py` (nagent §11)
+
+**Why it matters.** Manual Slop doesn't have an explicit split/patch pipeline. For very large files (>50 KB), the current `aggregate.py` + tree-sitter approach works for *reading* (skeleton, summary) but not for *patching* (no explicit segment/hash model).
+
+**What it would do.** Mirror nagent's design:
+- `src/split_lib.py` — per-language natural splitters, `index.json` with `source_path`, `sourcesha256`, `segments[]`
+- `src/patch_lib.py` — strict `validate_index` (hash check), `make_unified_patch`, `apply_segment_patches`
+- `src/summarize_lib.py` — per-segment LLM call + retry-with-smaller-prompt
+
+**Where it lives.** Application (the AI is the consumer). The Meta-Tooling already has nagent if it wants this.
+
+**Depends on.** None. Self-contained.
+
+**Effort.** **Medium.** 2 phases: split/patch, then summarize. ~500 lines.
+
+**Recommended priority.** **DEFER UNTIL NEEDED.** No current 1:1 use case requires explicit split/patch. If a future file is genuinely too large for tree-sitter to handle inline, this becomes Candidate #2-priority.
+
+---
+
+## Candidate 10: Optional raw-transcript persistence per Take (nagent §3 conversation dimension)
+
+**Why it matters.** nagent's "edit the conversation file" pattern is foreign to Manual Slop because the App stores abstracted entries (`disc_entries`), not raw transcripts. The user-edit feature in the GUI does edit individual entries, but the underlying log of `function_call` / `tool_result` blocks is implicit.
+
+**What it would do.** Optionally, when a take is snapshotted to TOML (`project_manager.save_project`), also persist the raw transcript to a sibling file `discussions/<take_name>/transcript.jsonl`. The GUI gets a "View Raw Transcript" button. Optional "Edit Raw Transcript" mode that re-parses and re-aggregates.
+
+**Where it lives.** Application. Optional — user can toggle per-project.
+
+**Depends on.** None. Could be a small follow-up to Candidate 3 (`Conversation` class).
+
+**Effort.** **Small.** ~150 lines + tests. Persist the existing `comms.log` in a structured way.
+
+**Recommended priority.** **LOW** — niche feature, opt-in only.
+
+---
+
+## Summary table
+
+| # | Candidate | User signal | Priority | Effort | Domain |
+|---|---|---|---|---|---|
+| 1 | `SubConversationRunner` (1:1 sub-convos) | **Explicit want** | **HIGH** | Medium | App + MT |
+| 2 | RAG pre-staging via sub-conversation | **Explicit want** | **HIGH** | Small (depends on #1) | App |
+| 3 | Stateless `LLMClient` class | (none) | Medium | Large | App |
+| 4 | Intent-based DSL for Meta-Tooling | Explicit but deferred | Low | Research | MT |
+| 5 | Self-describing MCP tools | Implicit | Low (subsumed) | Medium | BOTH |
+| 6 | `src/git_history.py` (nagent §7) | (none) | Medium | Medium | App |
+| 7 | Per-file conversation log | (none) | Low | Small | App |
+| 8 | `py_/ts_c_coedited_files` tools | (none) | Low (bundle with #6) | Small | App |
+| 9 | Explicit `split_lib.py` / `patch_lib.py` | (none) | Defer until needed | Medium | App |
+| 10 | Raw-transcript persistence per Take | (none) | Low | Small | App |
+
+---
+
+## Recommended next steps
+
+1. **Spec and build Candidate 1 first** — it's the highest-priority user-flagged want, and Candidates 2 builds on it.
+2. **Combine Candidate 2 with Candidate 1's track** — same primitive, different prompt.
+3. **Hold Candidates 3-10 for future scoping** — each is a separate conductor track when the corresponding need surfaces.
+
+The current `nagent_review_20260608` track itself produces no code; it's the reference. Candidates 1 and 2 will be the first *implementation* tracks informed by it.

+# nagent: Actionable Takeaways for Manual Slop
+
+**Track:** `nagent_review_20260608`
+**Date:** 2026-06-08
+**Companion to:** `report.md` (deep-dive comparison), `comparison_table.md` (flat reference), `decisions.md` (10 future-track candidates)
+**Author:** Tier 2 Tech Lead
+**Read this if:** you're planning a future track, designing a UX change, or wondering "what should we actually do with nagent's ideas?"
+
+> **What this document is.** The deep-dive in `report.md` maps nagent's 14 principles 1:1 to Manual Slop's existing features and finds six pitfalls. That's the *diagnosis*. This document is the *prescription* — 10 concrete patterns nagent uses that we can borrow, with each one grounded in actual code we've read and an explicit "what to do" path.
+>
+> **What this document is not.** It is not a critique of Manual Slop, not a recommendation to rewrite anything, and not a "framework migration" plan. nagent is a 4,000-line reference; Manual Slop is 13,000+ lines of production code with a GUI, real persistence, real HITL. The right reaction to nagent is *steal the patterns that fit our domain*, not adopt the whole system.

+> **Domain filter.** Every takeaway below is tagged **Application**, **Meta-Tooling**, or **Both** — per `docs/guide_meta_boundary.md`. nagent lives in the Meta-Tooling domain by default. Some patterns transfer cleanly to the Application; some only make sense for the agents that build the Application. Don't apply a "Both" pattern without checking the domain.
+
+---
+
+## 0. The 30-second version
+
+If you only read 3 things, read these:
+
+1. **Make state visible at the right layer** (§1) — nagent puts state in files you can `cat`. Manual Slop already does this for *editable* state (`disc_entries`, `ContextPreset`, `FileItem`, project TOML) but the *provider-side* history still lives in process globals. *Steal the visibility, not the file abstraction.*
+
+2. **Make the protocol readable in the conversation log** (§2) — nagent's conversation is plain text with `<nagent-shell>...</nagent-shell>` tags you can grep. Manual Slop's comms log is JSON-L with provider-native function-call blobs. *Add a "what the model actually said" projection layer.*
+
+3. **Make sub-agents a first-class primitive for the Application, not just MMA** (§3) — nagent has one sub-conversation mechanism, used everywhere. Manual Slop has sub-agents for MMA workers but not for 1:1 discussions. *The user explicitly wants this — it's the highest-priority future track.*
+
+The other 7 patterns are below. Each is grounded in code, not vibes.
+
+---
+
+## 1. State visibility — files for the things that matter, processes for the things that don't
+
+**nagent's pattern.** Every piece of state that *survives* lives in a file under `~/.nagent/`:
+- `conversations/<conversation_name>` — the conversation transcript
+- `conversations/file-index-{pid}.json` — file_id → conversation map
+- `splits/<slug>-<uuid>/index.json` — large-file split metadata
+- `splits/<slug>-<uuid>/<slug>-0001.<ext>` — segment files
+- `splits/<slug>-<uuid>/<slug>.patch` — unified diff patch
+
+The state that *doesn't survive* is the running process: LLM call result, current turn, parse state. The boundary is sharp: anything the user might want to inspect, diff, copy, or back up is a file.
+
+**Manual Slop today.** Already does this for the *editable* surface:
+- `manual_slop.toml` (project) — `discussion.discussions[<take_name>].history` (`app_controller.py:3236`)
+- `conductor/tracks/<id>/{spec,plan,state.toml,metadata.json}` — track state
+- `personas.toml` (global + project) — persona config
+- `tool_presets.toml` — tool weights
+- `logs/sessions/<session_id>/comms.log` — JSON-L of every LLM call (`app_controller.py:379`)
+
+What *isn't* in files:
+- `ai_client._anthropic_history`, `_deepseek_history`, `_minimax_history` — 3 per-provider lists in process globals (`ai_client.py:123-132`)
+- The current `disc_entries[i]["content"]` AI response *before* the user flushes the discussion to TOML
+- The current `files` / `context_files` / `screenshots` until the next `_flush_to_project`
+
+**Actionable idea.** Add a **"Live State Inspector"** panel in the GUI that shows *all* the state that's currently in process — provider history lengths, current discussion entry count, the actual bytes that haven't been flushed yet, the `ai_client` module globals being read. This is a UX change, not an architecture change. It costs ~200 lines (a panel that reads from `app_controller._get_state_for_inspector()` and renders a tree).
+
+**Domain:** Both. The Application benefits from "what is the AI actually remembering right now?"; the Meta-Tooling benefits from "did my edit actually flow through to the right state?"
+
+**Effort:** Small. *Not* a new track — this can be a one-day add-on once the inspector is specced.
+
+**Cross-references:** Decision candidate #3 (Stateless LLMClient) becomes more attractive once the inspector exists, because you'd have a UI to verify the stateless refactor preserves behavior.
+
+---
+
+## 2. A readable conversation log — text the user can grep, not just JSON-L
+
+**nagent's pattern.** The conversation file is plain text. Every action appears as a tag:
+```
+<nagent-shell>python3 -m unittest discover -s tests -v</nagent-shell>
+<nagent-shell-result>
+exit_code: 0
+stdout: ...
+</nagent-shell-result>
+<nagent-response>All 12 tests pass.</nagent-response>
+```
+
+The user can `grep -n "exit_code: [^0]" ~/.nagent/conversations/latest-*` to find all failed shell runs. The user can `git diff` the conversation file. The user can `cp` it to a teammate. The protocol is *the storage format*, not a side channel.
+
+**Manual Slop today.** `comms.log` is JSON-L with provider-native function-call blobs. To find "did the model call `read_file` with the right path?" you need to load JSON, navigate to the right `function_call` entry, know the provider's schema, and dig out the args. The `function_call` itself is opaque — you can't `grep` for it without understanding the provider's wrapping.
+
+The `app.disc_entries` GUI display *is* the readable projection — when you look at a discussion in the GUI, you see the user/AI turns. But:
+1. The view is in the GUI only; the underlying `comms.log` is JSON-L.
+2. The thinking trace, tool calls, and tool results are flattened into the entry's `content` field via `thinking_parser.py`. You see the *result* but not the *call* unless you open the read mode.
+3. There's no per-tool-call "View raw" button in the comms log panel (per `docs/guide_gui_2.md`).
+
+**Actionable idea — option A (small, UI-only).** Add a **"Reveal Raw"** toggle on the comms log panel that, when on, shows the JSON-L entry *next to* the rendered view, with the JSON pretty-printed. The user can copy either the rendered text or the raw JSON. ~100 lines.
+
+**Actionable idea — option B (medium, behavioral).** Project the conversation log into a sibling markdown file as it's written. Every `comms.log` entry gets a corresponding `<session_id>.md` line that says "model called `read_file('src/foo.py')` at <ts>." The user can `cat`, `grep`, or `tail -f` this file. The GUI reads from the same source of truth (the markdown) instead of from the JSON-L. ~300 lines + a streaming write hook in `ai_client`.
+
+**Domain:** Both. Option A is UI work in the Application. Option B benefits the Meta-Tooling more — an external agent that needs to understand what the Application AI did can read the markdown without parsing JSON-L.
+
+**Effort:** A is small. B is medium. **Pick A first**; the user-correction in `report.md §3` shows the user is already on top of editable-discussion nuance, so a small UX win here validates the larger bet.
+
+**Cross-references:** Decision candidate #6 (git-history injection) — the markdown projection is the same kind of "explicit data artifact for the AI's input/output" pattern, just for the comms log instead of git history.
+
+---
+
+## 3. Sub-agents as a first-class primitive for 1:1 discussions
+
+**nagent's pattern.** The `<nagent-conversation>` tag in `bin/nagent:execute_agent(...)` is the *only* sub-agent mechanism. Used everywhere: investigation, research, large-output work, debugging. The child is a fresh process with `Invocation = "delegated"`, an isolated conversation file, and a `<nagent-conversation-result>` tag returned to the parent with the child's exit code + output + stderr + token totals.
+
+**Manual Slop today.** Sub-agents exist for MMA:
+- `scripts/mma_exec.py` — Tier 3/4 worker subprocess
+- `src/multi_agent_conductor.py:run_worker_lifecycle` — worker lifecycle
+- `src/dag_engine.py` — ticket DAG and per-ticket worker pool
+
+But for 1:1 discussions (`simulation/workflow_sim.py:WorkflowSimulator.run_discussion_turn_async`), there's no sub-agent primitive. The user types a prompt, the AI responds, the loop continues. If the user wants the AI to "investigate this file" or "look up this API," the answer has to come from the same conversation.
+
+**Why it matters.** The MMA pattern is *already* the prototype. `mma_exec.py` is a real subprocess with Context Amnesia and a clean prompt boundary. The only thing missing is a way to invoke it from the 1:1 chat loop without going through the full MMA tier system.
+
+**Actionable idea.** Build `src/sub_conversation.py:SubConversationRunner` (Decision candidate #1, already specced in `decisions.md`):
+```python
+class SubConversationRunner:
+    async def spawn(
+        self,
+        prompt: str,
+        *,
+        allowed_tools: list[str] | None = None,
+        system_prompt: str | None = None,
+        timeout_s: int = 120,
+    ) -> SubConversationResult:
+        # Reuse mma_exec.py as the subprocess template
+        # Return the child's <nagent-response> content + token usage
+        ...
+```
+
+Wire it into the GUI as a new "Investigate…" button on the message panel (`gui_2.py:4513+`). The button opens a small modal: "Ask a sub-agent: ___ [Investigate]". The sub-agent runs, the result is inserted as a "User" role entry in the current discussion, and the next LLM call sees it.
+
+**Domain:** Application. (The Meta-Tooling could use the same primitive from `scripts/`, but the win is in the App.)
+
+**Effort:** Medium. 2-3 phases. **HIGH priority** because the user explicitly wants it.
+
+**Cross-references:** Decision candidate #2 (RAG pre-staging) is the natural second use of this primitive — a sub-conversation that pre-builds the RAG index before a long discussion.
+
+---
+
+## 4. File-identity over file-path — a stable `st_dev:st_ino` is rename-safe
+
+**nagent's pattern.** `nagent_file_edit_lib.py:file_id_for_path(path) -> "{st_dev}:{st_ino}"`. The per-file conversation index keys by inode, not by path. Rename the file in place (same inode) → same conversation. Move the file across dirs (same inode) → same conversation. This is the right primitive for "memory attached to the artifact, not the path."
+
+**Manual Slop today.** `models.FileItem.path: str` — path-keyed. `project.discussion.discussions[<take>].context_snapshot` is a list of `FileItem.to_dict()` dicts, indexed by position in the list. Rename the file in your editor → `FileItem.path` is stale, `aggregate.py:build_file_items` re-reads the old path, may fail. The curation memory *survives* the rename (it's keyed by name in the project TOML) but the file lookup at render time does not.
+
+**Actionable idea — small (additive).** Add a `file_id: str` field to `FileItem` populated at load time via `os.stat(path).st_dev:st_ino`. Use it as the lookup key in the `context_snapshot` list. On file-read failure, attempt a fuzzy match: same basename in the same directory tree, or same `file_id` under a new path. ~150 lines + a migration for existing project TOML files (path-only becomes path + file_id).
+
+**Actionable idea — bigger (architectural).** If you do this, also rethink the `ContextPreset` storage. The current schema is a flat list of `FileItem` dicts. nagent's analog is a per-file `IndexEntry { file_id, path, last_seen, conversation, last_summary }`. A path rename in nagent updates `path` in the index but leaves `file_id` stable; in Manual Slop a path rename would orphan the entire `FileItem`.
+
+**Domain:** Application. (The Meta-Tooling would benefit from a stable file_id when navigating references across many files in a long session.)
+
+**Effort:** Small (additive) or medium (architectural). The additive path is the right starting point; the architectural rewrite is overkill for a feature that already works for 95% of cases.
+
+**Cross-references:** Decision candidate #7 (per-file conversation log) — `file_id` is the prerequisite for this candidate.
+
+---
+
+## 5. One loop, one file — make the agent's brain visible by default
+
+**nagent's pattern.** `bin/nagent:run_agent_loop` is ~50 lines. `main()` reads CLI args, sets up the conversation file, calls `run_agent_loop`, exits. The conversation file accumulates over the entire session. The "agent" *is* the file plus a transient process.
+
+**Manual Slop today.** Three parallel loops, each in a different file:
+- `src/ai_client.py:_send_<provider>` (per-provider, ~100-200 lines each × 5 providers) — the LLM-call loop
+- `src/multi_agent_conductor.py:ConductorEngine.run` — the MMA loop
+- `simulation/workflow_sim.py:WorkflowSimulator.run_discussion_turn_async` — the 1:1 chat loop
+
+Each loop has the same shape (build prompt → call LLM → parse response → dispatch tools → repeat) but the data structures differ. A reader has to hold three mental models.
+
+**Actionable idea — UX win, not architecture change.** Surface the *unified loop shape* in the diagnostics panel. The diagnostics panel already exists (`gui_2.py` §"Diagnostics Hub" per the Readme). Add a section "Loop Inspector" that shows, for each of the three loops:
+- Last N iterations of: input tokens, output tokens, tool calls made, tool results, parse failures
+- Color-coded: same shape across all three loops, different data sources
+- "View raw" drill-down to the actual function call
+
+This is *not* a refactor. It's making the existing three loops legible. ~200 lines.
+
+**Actionable idea — bigger refactor.** Extract a `src/llm_loop.py:run_loop(conversation, provider, tool_dispatch, parse_response, ...)` that's called by all three. This is Decision candidate #5.5 (not in `decisions.md`; would be a new candidate). Effort: large. Value: real but the current separation is readable.
+
+**Domain:** Both. The UX win is in the Application. The refactor is neutral but helps the Meta-Tooling when agents need to reason about the loop.
+
+**Effort:** UX win is small. Refactor is large. **Do the UX win first.**
+
+**Cross-references:** Decision candidate #3 (Stateless LLMClient) — the refactor becomes more attractive if a unified loop exposes the data flow more clearly.
+
+---
+
+## 6. Visible retry on protocol failure — turn errors into conversation data
+
+**nagent's pattern.** `bin/nagent:run_agent_loop` has `MAX_FORMAT_RETRIES = 3`. On a parse failure:
+```python
+append_to_conversation(
+    conversation_file,
+    f"<agent-response>\n{llm_output}\n</agent-response>\n"
+    f"<system>Invalid nagent response format: {parse_error}. "
+    f"Respond only with valid nagent tags.</system>",
+)
+```
+
+The bad output is *appended to the conversation* with a `<system>` correction. The next call sees its own previous failure and the correction message. The user can `grep` the conversation for `<system>` to find every retry.
+
+**Manual Slop today.** `_send_<provider>` loops internally; on a tool-call parse failure it... retries. But the failure isn't visible in `comms.log` as a first-class entry — it's swallowed by the loop. The `tier4_qa` interceptor (per `docs/guide_ai_client.md` §"Tier 4 QA") catches *errors from tool execution* and forwards them to a cheap sub-agent for a 20-word summary, but parse failures don't go through this path.
+
+**Actionable idea — small, high value.** Add a `parse_failures` counter and a "Last 5 parse failures" section to the diagnostics panel. The counter increments on each `parse_response` failure; the section shows the model output, the error message, and the time. ~50 lines. The user gets to see *what* the model is getting wrong — useful for prompt engineering.
+
+**Actionable idea — medium, prompt-quality win.** When a parse failure happens, append a "self-correction" entry to `disc_entries` as a `role: "System"` entry. The next AI call sees the correction in the visible discussion history. The user can see the corrections and can edit them. ~150 lines.
+
+**Domain:** Both. The diagnostics panel is Application UX. The self-correction entry is neutral — useful for any agent that reads `disc_entries`.
+
+**Effort:** Small for option 1. Medium for option 2. **Do option 1 first.**
+
+**Cross-references:** nagent §5 "The loop" — the retry visibility is a load-bearing part of nagent's debuggability claim.
+
+---
+
+## 7. "Inspect this file" / "Read this URL" as *prompts*, not function calls
+
+**nagent's pattern.** `<nagent-read path="..."/>` is a self-closing tag. The model emits it; the parser matches; `execute_read` runs. The model doesn't need to know the function-call schema for the LLM SDK — it just needs to emit text containing a tag.
+
+**Manual Slop today.** `read_file(path)` is a function call. The model has to know the function signature, format the JSON, embed it in the right `tool_use` block. The training data for "emit a `<nagent-read>` tag" is zero; the training data for "emit a `read_file` tool call" is high. *Function calling wins on capability and on training*; *tag protocols win on debuggability*.
+
+**Actionable idea — both, but in different places.** This is the *one* place where the existing reports lean toward "different mechanism, both right." Don't replace the Application's function calling. But for the Meta-Tooling, document a *Meta-Tooling DSL* in `conductor/code_styleguides/` for use by external agents when they need to invoke Manual Slop's tools via the bridge script. The DSL would look like:
+```
+<ms-tool name="read_file" path="src/foo.py" />
+<ms-tool name="py_get_skeleton" path="src/foo.py" symbol="MyClass" />
+```
+
+The bridge script (`scripts/mma_exec.py` or whatever the Meta-Tooling bridge is) translates these to the underlying function calls. The external agent's prompt training data does *not* need to know the function-calling JSON schema for every Manual Slop tool — it just needs to know the DSL.
+
+**This is Decision candidate #4 (intent-based DSL) from `decisions.md`** — but reframed: it's not a Meta-Tooling-*side* DSL, it's a *bridge* DSL. The Application's function-calling stays.
+
+**Domain:** Meta-Tooling. The Application doesn't need this.
+
+**Effort:** Research spike, per the user's own assessment: "no where near that ideation yet." Document the design space; don't build it.
+
+**Cross-references:** Decision candidate #4. Also nagent §12 (tool discovery) — the DSL would be the bridge-side analog of `--description` self-describing executables.
+
+---
+
+## 8. Self-describing tools — let the tool tell the agent what it does
+
+**nagent's pattern.** `nagent_cli.py:exit_on_description(description)` is called at the top of every executable:
+```python
+def exit_on_description(description: str) -> None:
+    if "--description" in sys.argv:
+        print(description)
+        raise SystemExit(0)
+```
+
+`nagent_cli.py:collect_bin_tool_descriptions(bin_dir)` runs each tool in `bin/` with `--description`, captures stdout, concatenates. The startup prompt includes the concatenated descriptions automatically. *Adding a new tool is: drop a script, write a description.* The system auto-discovers.
+
+**Manual Slop today.** `src/mcp_client.py:dispatch(...)` is a flat if/elif chain with 45+ branches. Adding a tool requires:
+1. Edit `dispatch()` to add the branch
+2. Update the security allowlist in `_resolve_and_check` (if filesystem access)
+3. Update the AI capability declaration in `get_tool_schemas()`
+4. Add tests
+
+**Actionable idea — defer to `mcp_architecture_refactor_20260606`.** This is already on the board as Decision candidate #5 (subsumed). The "sub-MCP" extraction that the refactor proposes is *exactly* the right scope for the self-describing pattern — each sub-MCP is a self-contained module with its own tool registry, and `collect_tool_descriptions` becomes a method on the sub-MCP class.
+
+**Don't** try to add this incrementally. The dispatch chain is large enough that half-measures (e.g. a per-tool decorator that auto-registers but still requires a manual allowlist edit) are net-negative. Wait for the refactor.
+
+**Domain:** Both. (Largely Application — the dispatch is in `mcp_client.py`. But the pattern would also be useful for the Meta-Tooling's `scripts/` directory.)
+
+**Effort:** Subsumed by `mcp_architecture_refactor_20260606`.
+
+**Cross-references:** Decision candidate #5. Already documented.
+
+---
+
+## 9. Edit-the-input, not the output — make the prompt the artifact
+
+**nagent's claim (verbatim from README).** *"Don't edit the output artifacts. Edit the prompt."* If the LLM gives a bad answer, the fix is in the prompt or the inputs — not by hand-patching the output. The conversation file *contains* the prompt. Editing the conversation is editing the prompt for the next turn.
+
+**Manual Slop today.** The user can edit any `disc_entries[i]["content"]` directly via the `[Edit]` mode in the GUI (per `report.md §3 A1`). But the edited entry goes into the *abstracted entry list*, not into the *raw provider history*. The next LLM call sees:
+- The full `disc_entries` rendered as markdown (with the user's edits)
+- BUT the `ai_client._anthropic_history` (and siblings) is the *raw* provider-side list, with the *original* AI response and the *original* function calls
+
+So the user edits the *projection* but not the *source*. If the user corrects an AI response that included a bad tool call, the *display* shows the correction but the *provider's next call* will replay the original bad tool call as a "previous tool result" in the history. The two diverge.
+
+**This is subtle but important.** nagent avoids this entirely because the conversation file *is* the prompt — there's no separate "raw provider history" to keep in sync.
+
+**Actionable idea — small, surgical.** When the user edits an entry's `content` in `[Edit]` mode, *also* rewrite the corresponding `ai_client._<provider>_history[i]["content"]` to match. The user sees one source of truth; the provider sees the same source of truth. ~100 lines + a careful test for Anthropic's content-block semantics (it has multiple content blocks per message, not a single string).
+
+**Actionable idea — bigger, the right architecture.** Stop maintaining two histories. Make `disc_entries` the *only* history. `ai_client._<provider>_history` becomes a *projection* of `disc_entries`, rebuilt on each send(). This is part of Decision candidate #3 (Stateless LLMClient) — the `Conversation` object becomes the single source of truth.
+
+**Domain:** Both. The edit-the-projection fix is Application UX. The single-history architecture is Application + (benefiting) Meta-Tooling.
+
+**Effort:** Small for option 1, large for option 2. **Option 1 is the right starting point** — it's a known issue with a known fix, and the user-correction in `report.md §3` shows the user is on top of editable-discussion nuance.
+
+**Cross-references:** Decision candidate #3 (Stateless LLMClient). Also nagent §3 (conversations are editable state) — the philosophy is "one editable source of truth," and Manual Slop currently has two.
+
+---
+
+## 10. Sub-agents return a *concise artifact*, not a full transcript
+
+**nagent's pattern.** `<nagent-conversation-result conversation="..." tokens_in="..." tokens_out="...">` contains only the child's `<nagent-response>` body + exit code + stderr. The parent's conversation is *not* polluted with the child's intermediate reads, shell calls, or retries. The parent gets a *distilled* result.
+
+**Manual Slop today (MMA path).** `multi_agent_conductor.py` returns the worker's final response to the parent (the `ConductorEngine`). The worker's intermediate steps are logged to `comms.log` but not propagated. So MMA *does* follow the nagent pattern for sub-agent outputs. *This is good.*
+
+**Manual Slop today (1:1 chat, no sub-agents).** No equivalent. The user can't ask a sub-agent and get a distilled answer. The whole point of the user-flagged Decision candidate #1 is to add this — and the implementation should follow nagent's pattern: the sub-agent returns a *string artifact*, not its full conversation log.
+
+**Actionable idea — design constraint on the upcoming track.** When implementing Decision candidate #1 (SubConversationRunner), specify the return type as `SubConversationResult { artifact: str, tokens_in: int, tokens_out: int, exit_code: int, errors: list[str] }`. Do *not* return the child's full conversation. The parent's `disc_entries` gets one new "User" entry containing `artifact`. The child's full transcript is persisted to `~/.manual_slop/sub_conversations/<uuid>.jsonl` for debugging but is not in the parent's visible discussion.
+
+**Domain:** Application (this is the design constraint for candidate #1).
+
+**Effort:** Zero net new effort — this is a design constraint, not a feature. Bake it into the spec for candidate #1.
+
+**Cross-references:** Decision candidate #1. nagent §9 (sub-conversations). The `MAX_FORMAT_RETRIES = 3` retry budget in nagent also informs the design — the sub-agent should be allowed to retry internally, but its final artifact to the parent should be a single string.
+
+---
+
+## Cross-cutting observations (not patterns, but framing)
+
+### A. nagent's "files are the system" is the same philosophy as Manual Slop's project TOML + conductor tracks
+
+The *philosophy* of nagent — that data lives in files you can `cat`, `git diff`, and `cp` — is already present in Manual Slop:
+- `manual_slop.toml` is the project's source of truth
+- `conductor/tracks/<id>/state.toml` is the track's state
+- `personas.toml`, `tool_presets.toml`, `context_presets.toml` are all TOML
+- The Hook API exposes this state via `POST /api/project` for external automation
+
+What's *not* yet at that level: the AI's working state (the in-flight `disc_entries`, the provider history globals). Closing this gap is the theme of Decision candidates #3, #7, and #10.
+
+### B. nagent is small because it has no GUI. Don't be jealous of the size.
+
+nagent: ~4,000 lines. Manual Slop: 13,000+ lines of production code + 5,000+ lines of MCP tools + a 5,000-line GUI. The size difference is the GUI, the persistence, the test harness, the HITL dialogs, and the Hook API. None of those are reducible by adopting nagent's patterns; they're features Manual Slop users want and use. The right comparison is "nagent's *patterns* vs Manual Slop's *implementation*," not "which codebase is smaller."
+
+### C. The user-corrections shaped the takeaways
+
+Three user-corrections during the deep-dive review directly influenced which patterns made this list:
+- **"Editable discussions are more comprehensive than the first draft said"** → made takeaway #1, #2, #9 (visibility, log readability, single-history) all about *respecting* what Manual Slop already has rather than suggesting it lacks.
+- **"MMA is fine; 1:1 sub-agents are the gap"** → made takeaway #3 (sub-agents for 1:1) the highest-priority actionable item, with #10 (sub-agent return type) as the design constraint.
+- **"Personas are config bundling, RAG is opt-in, tool discovery is deferred"** → kept those three out of the "must steal" list. They're in the future-track `decisions.md` but not in *this* document.
+
+The takeaways are *user-shaped* as well as nagent-shaped. If the user had a different correction in any of those areas, the takeaway list would shift.
+
+---
+
+## Recommended reading order for a future implementer
+
+If you're about to build one of the future tracks, read in this order:
+
+1. **Track 1 — Sub-conversation runner (Application):** Read this entire document, especially §3 and §10. Then read `decisions.md` candidate #1. Then read `src/multi_agent_conductor.py:run_worker_lifecycle` and `scripts/mma_exec.py` for the template.
+
+2. **Track 2 — RAG pre-staging (Application):** Read this entire document, especially §3 (the parent). Then read `decisions.md` candidate #2. Then read `src/rag_engine.py:index_file` and `docs/guide_rag.md`.

+## Final note: this is a *reference* track
+
+This document does not commit any of the 10 takeaways to implementation. Each is a *candidate* — a design space, not a decision. The user (the product owner) and the Tier 2 Tech Lead will scope each into a real conductor track when the corresponding need surfaces. The fact that these patterns are *all grounded in code I've read* (nagent + Manual Slop) is the value of this document; the patterns themselves are *raw material for future work*, not commitments.

+# Mike Acton's nagent: A Deep-Dive Analysis vs Manual Slop
+
+**Track:** `nagent_review_20260608`
+**Date:** 2026-06-08 (revised with user corrections same day)
+**Author:** Tier 2 Tech Lead (with significant user review on §3 and §6)
+**Companion to:** `spec.md` (the track wrapper)
+
+> **Important reading note.** This report applies the **Application vs Meta-Tooling distinction** (per `docs/guide_meta_boundary.md`) as the lens for every comparison. nagent is a Meta-Tooling reference; Manual Slop's Application AI is a *different kind of thing*. Where they share patterns (MMA workers, the tool-call loop, the 3-layer security model), the report says so. Where they don't, the report says so. The report deliberately avoids "nagent is better" / "Manual Slop is better" framings.
+>
+> **Revision note.** The first draft overstated gaps in Manual Slop's "editable discussion" and "per-file memory" features. The user caught this and pointed at the actual files (`FileItem`, `ContextPreset`, `aggregate.py`, `project_manager.branch_discussion`, `HistoryManager`). The corrections are now folded in. Specific corrections: §3 (verdict changed from PARTIAL to **PARITY (DIFFERENT FOCUS)**); §6 (verdict changed from DOMAIN MISMATCH to **MANUAL SLOP IS STRONGER IN THE CURATION DIMENSION**); §9 (verdict now notes the MMA vs 1:1 distinction explicitly per the user).
+
+---
+
+## 0. Reading guide
+
+- **Sections 1-14** map 1:1 to nagent's 14 principles. Each has: nagent's claim, nagent's implementation, Manual Slop's equivalent, a verdict, and a domain tag.
+- **Section 15** extracts the 6 actionable pitfalls and maps each to a future-track candidate.
+- **Section 16** is the recommended reading path for engineers who haven't read nagent.
+
+If you only have 10 minutes, read §3 (Conversations), §6 (Per-File Memory), §9 (Sub-Conversations), §10 (Controlled Writes), and §15 (the pitfalls list).
+
+---
+
+## 1. Durable work, disposable workers
+
+**nagent's claim.** A Python process is a *worker*; the files are the *system*. Workers come and go; data stays. **"The agent is not the thing; the data is the thing."**
+
+**nagent's implementation.** `bin/nagent` is a 700-line single-file loop. It reads `~/.nagent/conversations/<conversation_name>` (a plain text file) for the current conversation, appends to it after every action, and exits. The user types `nagent "investigate this"`. The CLI is a shell. The state is a file.
+
+**Manual Slop's equivalent.** Manual Slop has two parallel systems:
+
+1. **MMA workers are real subprocesses.** `multi_agent_conductor._spawn_worker` runs `mma_exec.py` via `subprocess.Popen` (per `docs/guide_multi_agent_conductor.md` §"Token Firewalling"). Each Tier 3 worker is a fresh Python process with **Context Amnesia** — `ai_client.reset_session()` at the start of `run_worker_lifecycle`. The subprocess is the disposable worker; the artifacts (track state, ticket results) are the system.
+
+2. **The Application AI is *not* a disposable worker.** `gui_2.py:App` is a long-lived Qt/ImGui process. The user types a prompt, hits Enter, gets a response, *keeps the process running for hours*. The `app_state` dataclass is the long-lived worker. This is *intentional* for the Application domain: persona-driven conversations, snapshot-based undo, cross-discussion state — all require a long-running process.
+
+**Verdict.** **PARTIAL** — nagent's pattern lives in the Meta-Tooling + MMA, but the Application deliberately has long-lived workers. The two coexist because they serve different needs: MMA is fire-and-forget per ticket; App is an interactive partner.
+
+**Domain tag:** Both. MMA has it; App doesn't need it. *Future-track candidate: a stateless conversation-file pattern for the App (see §15.4).*
+
+---
+
+## 2. Text in, text out
+
+**nagent's claim.** The smallest useful primitive is: file in, text out. `nagent-llm-text --file question.txt` reads a file, calls the LLM, prints plain text or JSON. Everything else in nagent is orchestration around this.
+
+**nagent's implementation.** `bin/helpers/nagent_llm.py` (300 lines) provides `generate_text(message, provider, model) -> str` for 4 providers (openai, anthropic, google, cursor). Token accounting via provider usage metadata (with character-count fallback at 1 token per 4 chars). Provider churn is isolated in this file.
+
+**Manual Slop's equivalent.** `src/ai_client.py:send(...) -> str` is the parallel. 5 providers (gemini, anthropic, deepseek, minimax, gemini_cli). Same `provider, model, usage` shape. Manual Slop wraps the string in a larger `(md_content, user_message, base_dir, file_items, ..., rag_engine) -> str` because the Application's text-in/text-out also needs tool calls, RAG injection, tier attribution, and patch-mode. But the *primitive* is the same.
+
+**Verdict.** **PARITY.** nagent and Manual Slop both use text-in/text-out at the bottom. The Application's `send()` is a *strict superset* of nagent's `nagent-llm-text`, with provider churn still isolated to a single module.
+
+**Domain tag:** Both. Meta-Tooling uses the same primitive via `mma_exec.py`'s `ai_client.send`.
+
+---
+
+## 3. Conversations are editable state
+
+**nagent's claim.** The conversation file is not chat history. It is working state. Memory goes stale; therefore let people save, load, summarize, edit, branch, trim, copy, diff, version, and rewrite conversations. **"The conversation does not own its memory. The user does."**
+
+**nagent's implementation.**
+- `bin/nagent` exposes `--save-conversation <name>`, `--load-conversation <name>`, `--summarize`, `--edit-conversation <prompt>`. The latter **automates** one path: archive current file, run file-edit on the archive, load the result.
+- Conversations are plain text files. The user can `cat`, `vim`, `git diff`, or `cp` them with no special tooling. The `<nagent-response>` body and `<nagent-shell-result>` body are just text in the file.
+- The first draft of this section understated Manual Slop's editing capability. The corrected picture is below.
+
+**Manual Slop's equivalent (corrected, with the full operation matrix).** Manual Slop's discussion editing lives at **three nested layers**, each with its own operations. The full enumeration:
+
+**Layer A — Per-entry operations on `app.disc_entries: list[dict]`** (the discussion's typed message list). The renderer is `src/gui_2.py:3770 render_discussion_entry(...)`. Per entry, the user can:
+
+| # | Operation | GUI control | Source code | What it does |
+|---|---|---|---|---|
+| A1 | **Edit content in place** | `imgui.input_text_multiline` on the entry body | `gui_2.py:3841` | The entry's `content` field is a fully editable multi-line text input. The user can rewrite an AI's response, fix a typo in their own prompt, paste in code from another source, etc. |
+| A2 | **Toggle read/edit mode** | `[Edit]` / `[Read]` button | `gui_2.py:3799` | When in `[Read]` mode, the content is rendered as Markdown with syntax highlighting (`render_discussion_entry_read_mode` at `gui_2.py:3855`). When in `[Edit]` mode, the multi-line text input is shown. |
+| A3 | **Toggle collapsed/expanded** | `+/-` button per entry | `gui_2.py:3789` | Collapsed entries show a 60-char preview (line 3822-3824). Expanded entries show full content. |
+| A4 | **Change role** | Combo box from `app.disc_roles` | `gui_2.py:3793-3796` | The entry's `role` field is editable. The list `app.disc_roles` is itself user-managed (see B5). |
+| A5 | **Insert entry before this one** | `Ins` button | `gui_2.py:3813` | `app.disc_entries.insert(index, {"role": "User", "content": "", "collapsed": True, "ts": project_manager.now_ts()})` |
+| A6 | **Delete this entry** | `Del` button | `gui_2.py:3815-3816` | `if entry in app.disc_entries: app.disc_entries.remove(entry)`. The membership check matters — ImGui can re-render stale state, so the check guards against double-delete. |
+| A7 | **Branch at this entry** | `Branch` button | `gui_2.py:3821` → `app._branch_discussion(index)` → `app_controller._branch_discussion:3503` → `project_manager.branch_discussion:429` | Creates a new Take named `<base>_take_<n>` and copies the history up to and including `index` into the new Take. The user is then switched to the new Take. |
+
+The entry dict shape itself is open: `{"role": str, "content": str, "collapsed": bool, "ts": str, ...}` plus optional `thinking_segments` (for AI entries with `<thinking>` blocks, parsed by `src/thinking_parser.py`) and `usage` (for token accounting: input/output/cache). The user can also set per-entry `read_mode` (a render-time flag, not persisted).
+
+**Layer B — Discussion-level operations** (the Take / discussion set). These are the second-tier controls, rendered at `src/gui_2.py:4239 render_discussion_entry_controls(...)` and the discussion selector at `gui_2.py:4330 render_discussion_selector(...)`:
+
+| # | Operation | GUI control | Source code | What it does |
+|---|---|---|---|---|
+| B1 | **Append new entry** | `+ Entry` button | `gui_2.py:4240` | `app.disc_entries.append({...})` with the default role from `app.disc_roles[0]`. |
+| B2 | **Collapse all / Expand all** | `-All` / `+All` buttons | `gui_2.py:4242-4246` | Bulk-set `collapsed` flag on every entry. |
+| B3 | **Clear all** | `Clear All` button | `gui_2.py:4248` | `app.disc_entries.clear()`. |
+| B4 | **Save (flush to project TOML)** | `Save` button | `gui_2.py:4250` | `app._flush_to_project(); app._flush_to_config(); app.save_config()`. |
+| B5 | **Add/remove roles** | `Add` / `X` buttons under "Roles" | `gui_2.py:4317-4328` | `app.disc_roles.append(r)` / `app.disc_roles.pop(i)`. The role list is **user-managed at runtime** — they can add `"Context"`, `"Tool"`, `"Vendor API"`, or any custom role and assign it to any entry. |
+| B6 | **Switch active discussion** | Discussion combo + Take tabs | `gui_2.py:4197, 4344, 4354` | `app._switch_discussion(name)`. The Takes group by base name (`name.split("_take_")[0]`) and render as nested tabs. |
+| B7 | **Rename / Delete discussion** | `Rename` / `Delete` buttons | `gui_2.py:4291, 4293` | `app._rename_discussion(...)` / `app._delete_discussion(...)`. Cannot delete the last discussion (guarded at `app_controller.py:3543`). |
+| B8 | **Promote Take to top-level** | `Promote` button in takes panel | `gui_2.py:4364` | `project_manager.promote_take(app.project, app.active_discussion, new_name)` — renames a Take (e.g. `T0_take_2`) to a fresh top-level discussion name. |
+| B9 | **Per-role filter** | `ui_focus_agent` selector (system-wide) | `gui_2.py:4230-4234` | `display_entries = [e for e in app.disc_entries if e.get("role") == persona_name or e.get("role") == "User"]`. The filter follows the MMA persona focus. |
+| B10 | **Truncate to N pairs** | `Truncate` button + `drag_int` | `gui_2.py:4254-4260` | `truncate_entries(app.disc_entries, app.ui_disc_truncate_pairs)` keeps the last `N` User/AI pairs (per `gui_2.py:175 truncate_entries(...)`). |
+| B11 | **Compress (AI summarization)** | `Compress` button | `gui_2.py:4252` → `app_controller._handle_compress_discussion:3357` | Calls `ai_client.run_discussion_compression(disc_text)` and replaces the discussion with the LLM's compressed version. |
+
+**Layer C — UI snapshot history (undo/redo).** The `HistoryManager` (`src/history.py:71`, `max_capacity=100`) and `UISnapshot` (`history.py:8-63`) provide Ctrl+Z / Ctrl+Y across the entire UI state — including `disc_entries`:
+
+| # | Operation | Source code | What it does |
+|---|---|---|---|
+| C1 | **Take snapshot** | `gui_2.py:735 _take_snapshot` → `history.UISnapshot(...)` | `copy.deepcopy(self.disc_entries)` — a deep copy of the full entry list is captured. The snapshot also captures `ai_input`, `temperature`, `top_p`, `max_tokens`, `auto_add_history`, `files`, `context_files`, `screenshots`, all system prompts. |
+| C2 | **Apply snapshot (undo/redo)** | `gui_2.py:754 _apply_snapshot` | Restores `self.disc_entries = snapshot.disc_entries` (and all the other fields). |
+| C3 | **Change detection triggers snapshot** | `gui_2.py:1160, 1166-1167` | `if len(current.disc_entries) != len(self._last_ui_snapshot.disc_entries) or ...` — disc_entries content change pushes a new snapshot. |
+| C4 | **Capacity-evict oldest** | `history.py:80-90 push()` | When the undo stack exceeds 100, the oldest is popped from the front. |
+| C5 | **Jump to specific state** | `history.py:129 jump_to_undo(index, current_state, ...)` | Allows time-traveling to any past snapshot, not just the most recent. |
+
+**Summary of editability.** Manual Slop provides:
+- **Per-entry content edit** (A1, A2) — the AI's response text is fully editable in the GUI
+- **Per-entry insert at any position** (A5) — the user can drop a new entry *between* two existing entries, not just append
+- **Per-entry delete at any position** (A6)
+- **Per-entry role change** (A4) — the user can re-label any entry as User, AI, Tool, Context, or any custom role
+- **Per-entry branch** (A7) — creates a Take at any entry, not just at the end
+- **Per-entry collapse/expand** (A3) — visual organization
+- **Per-discussion full CRUD** (B1, B6, B7, B8) — append, switch, rename, delete, promote
+- **Per-role set management** (B5) — the role list itself is user-editable
+- **Bulk operations** (B2, B3, B10) — collapse/expand all, clear, truncate
+- **AI-assisted compression** (B11) — summarize the whole discussion
+- **Undo/redo across all of the above** (C1-C5) — Ctrl+Z / Ctrl+Y / jump-to-state
+
+**What Manual Slop does NOT have.** The user cannot edit the **provider-side raw transcript** — the bytes inside the `ai_client._anthropic_history`, `ai_client._gemini_chat._history`, etc. process globals. These are reset on `ai_client.reset_session()`. nagent's "edit the conversation file" pattern operates at *this* layer, not the entry abstraction. The comms log (`comms.log`) is JSON-L and append-only, not user-editable from the GUI (it can be edited on disk in a text editor, but that's a different workflow).
+
+**Verdict.** **PARITY (DIFFERENT FOCUS).** Both systems support comprehensive editing of the conversation-as-data. The difference is *what counts as "the conversation"*:
+- nagent's "conversation" = the raw transcript text file (the bytes the LLM produced)
+- Manual Slop's "conversation" = a typed entry list with role + content + metadata + optional thinking segments
+
+Manual Slop's editing is **more granular and more pervasive** (per-entry content edit, per-entry insert/delete, per-entry role-change, per-entry branch, with undo/redo). nagent's editing is **deeper at the raw transcript layer** (edit the actual AI response text before it's been abstracted into a typed entry). Both are real; both are deliberate.
+
+**Domain tag:** Application. The Application's typed-entry abstraction is intentional — the user thinks in "discussions" not "transcripts." The user can opt-in to the raw-transcript layer by editing `comms.log` on disk or by reading the TOML `discussions/<take_name>/history` field directly.
+
+*Future-track candidate: optionally persist the raw transcript as a sibling file under each take (Candidate 10 in `decisions.md`), enabling the nagent-style "edit the actual AI response" workflow for users who want it.*
+
+---
+
+## 4. Visible output protocol
+
+**nagent's claim.** Free-form model output is hard to execute. Use a visible protocol: `<nagent-read>`, `<nagent-file-read>`, `<nagent-shell>`, `<nagent-write>`, etc. The startup prompt lists the only tags the model may emit. The parser is strict: recognized tags and whitespace. Nothing else. **"If you cannot read the protocol, you cannot debug the system."**
+
+**nagent's implementation.** `bin/nagent:TAG_PATTERNS` is a list of `(tag_type, compiled_regex)` tuples. `parse_response()` returns `None, error` if any non-whitespace text is found outside a known tag. The error message is appended to the conversation and the model is asked to retry (up to `MAX_FORMAT_RETRIES = 3`).
+
+**Manual Slop's equivalent.** Manual Slop's Application AI uses **provider-native function calling** (Gemini `genai.types.FunctionDeclaration`, Anthropic `tool_use` blocks, etc.). This is *opaque*: the protocol is encoded in JSON the provider parses. The user cannot read a `function_call` from the comms log and reason about it without knowing the provider's schema.
+
+The two approaches are **structurally different**:
+
+| Aspect | nagent regex tags | Manual Slop function calling |
+|---|---|---|
+| Visibility | Plain text, inspectable in the conversation file | JSON blobs in provider-specific format |
+| Per-provider portability | Same tags work across all 4 providers | Each provider has its own schema; mcp_client's 45 tools have 5 different per-provider formats |
+| Provider capability ceiling | Whatever the model can emit as text | Native parallel tool calls, structured outputs, JSON-mode constraints |
+| Debuggability | "Why didn't the model read the file?" → grep the conversation for the tag | "Why didn't the model call read_file?" → inspect the JSON response |
+
+**Verdict.** **ARCHITECTURAL DIFFERENCE** — both are correct for their domain. The Application *wants* parallel tool calls, JSON-mode constraints, and provider-side caching. The Meta-Tooling *might want* nagent's regex tags for explicit debuggability.
+
+**Domain tag:** Both. The Application's choice is right (modern providers all support function calling with parallel execution — see `docs/guide_ai_client.md` §"Async Tool Execution"). The Meta-Tooling *could* adopt nagent's regex-tag protocol for its own work — for example, by using `<read src/foo.py>` instead of a tool-call JSON. This is explicitly the difference between the "Application's internal AI" and the "Meta-Tooling that builds the Application" in `docs/guide_meta_boundary.md`.
+
+*Future-track candidate: a Meta-Tooling-side DSL for compact tool calls (per the existing `docs/reports/PLANNING_DIGEST_20260606.md` reference to "an intent-based DSL" for "discovery" or "combinatorics").*
+
+---
+
+## 5. The loop (append, call, parse, act, append, repeat)
+
+**nagent's claim.** "Agent behavior" is mostly: append, call, parse, act, append, repeat. Heavier systems add infrastructure around the same steps.
+
+**nagent's implementation.** `bin/nagent:run_agent_loop` is a `while True` loop:
+1. Append user prompt to conversation file
+2. Send conversation file to LLM (via `nagent-llm-text --json`)
+3. Append response to conversation file
+4. If response contains action tags: run those actions, append results, continue loop
+5. If response contains `<nagent-response>`: print and stop
+
+**Manual Slop's equivalent.** Manual Slop has *three* parallel "loops":
+
+1. **`src/ai_client.py:_send_<provider>`** — the per-provider tool-call loop. Up to `MAX_TOOL_ROUNDS + 2 = 12` iterations. Each round: call provider, parse function calls, dispatch, append tool results. Same shape as nagent.
+
+2. **`src/multi_agent_conductor.py:ConductorEngine.run`** — the MMA loop. Per ticket: `ai_client.reset_session()` (Context Amnesia), build prompt, `loop.run_in_executor(None, run_worker_lifecycle, ...)`. Different scope (per ticket, not per user turn).
+
+3. **`simulation/workflow_sim.py:WorkflowSimulator.run_discussion_turn_async`** — the 1:1 chat loop. Per user turn: build markdown, send, wait, append response. Different scope (per user turn, in the App).
+
+All three have the same "append, call, parse, act, repeat" shape. They differ in *what gets appended* (per-provider history vs track state vs `disc_entries`).
+
+**Verdict.** **PARITY.** The loop is the universal pattern. Manual Slop's three loops are at different layers (LLM, MMA, App). The lack of a *single* "the loop" file is a real cost — nagent's `run_agent_loop` is 50 lines, easy to reason about. Manual Slop's loops are 100-300 lines each, scattered.
+
+*Future-track candidate: a single `src/llm_loop.py:run_loop(...)` function that all three callers use, with the dispatch and parse layers injected. (Not a high-priority refactor; the current separation is readable.)*
+
+**Domain tag:** Both.
+
+---
+
+## 6. Per-file memory (curation, not conversation log)
+
+**nagent's claim.** One conversation grows too large. Attach memory to artifacts. Work keeps coming back to the same files; give each file its own persistent local memory. **"When work orbits one artifact, store memory on that identity."**
+
+**nagent's implementation.** `bin/helpers/nagent_file_edit_lib.py` provides:
+- `file_id_for_path(path) -> "{st_dev}:{st_ino}"` — a stable file identity across renames (the inode is preserved).
+- `file_index_path(root, pid) -> conversations/file-index-{pid}.json` — a JSON registry of `{file_id: {path, conversation}}`.
+- `resolve_file_edit_conversation(root, pid, file_path) -> (name, resolved, file_id)` — gets or creates a per-file conversation.
+- `nagent-file-edit --file src/foo.py "add validation"` — spawns a new nagent process with `--file_edit src/foo.py`, which loads the file's *previous* conversation as the initial context. After edits, the new file is appended to the same conversation.
+
+The result: a per-file conversation log keyed by inode. Rename with same inode = same conversation. Pure path-based: nope, you'd collide across two repos on the same machine.
+
+**Manual Slop's equivalent (corrected per user).** The first draft of this report marked this section as "DOMAIN MISMATCH" — claiming Manual Slop has no per-file memory. **This was wrong.**
+
+Manual Slop *does* have a per-file memory concept. It's just **a different kind of memory**. Where nagent's per-file memory is a *conversation log* (what the LLM said about this file last time), Manual Slop's is a *curation config* (how to present this file in the AI's context window). The two are complementary, not equivalent.
+
+The Manual Slop per-file memory:
+
+```python
+# src/models.py:510
+@dataclass
+class FileItem:
+    path:               str                # the artifact identity (path-keyed, no inode)
+    auto_aggregate:     bool = True       # include in auto-aggregation?
+    force_full:         bool = False      # bypass aggregation with full content?
+    view_mode:          str = 'full'      # full / skeleton / summary / sig / def / agg
+    selected:           bool = False      # for batch operations
+    ast_signatures:     bool = False      # only signatures
+    ast_definitions:    bool = False      # only definitions
+    ast_mask:           dict[str, str]    # per-symbol mask (from Structural File Editor)
+    custom_slices:      list[dict]        # Fuzzy Anchor slices with tag+comment
+    injected_at:        Optional[float]   # timestamp
+```
+
+Plus the **ContextPreset** (`src/models.py:909`): a *named, persisted set* of `FileItem`s, stored in the project's `manual_slop.toml`. Load a preset → restore the same per-file curation state. This is the per-file memory that survives across discussions.
+
+The user pointed at this directly: *"we have the context composition we can directly control what's in memory at the start of a discussion."* That's the right framing. `aggregate.py:run` builds the initial markdown from `self.context_files` (the active preset's FileItems) + `aggregate.run(flat, aggregation_strategy=...)`. The user controls the per-file memory at discussion start.
+
+What's *missing* is nagent's specific pattern: **a per-file conversation log keyed by inode.** Manual Slop does not have a "last investigation of this file" concept stored as a file. The closest analog is *commit history* (the discussion itself is git-linked, per `docs/guide_gui_2.md` §"Discussions Sub-Menu" "Git Commit Tracking"). But that's discussion-scoped, not file-scoped.
+
+**Verdict.** **MANUAL SLOP IS STRONGER IN THE CURATION DIMENSION; nagent IS STRONGER IN THE CONVERSATION-LOG DIMENSION.** Both have a real per-file memory concept. Manual Slop's is "how do I render this file next time the AI sees it" (rich, with 9 fields, AST-aware); nagent's is "what did the LLM say about this file last time" (plain text, with stable inode identity). The two are not equivalent; they're different optimizations for different needs.
+
+**Domain tag:** Application (for the curation config). The user-correction explicitly said: *"we have the context composition we can directly control what's in memory at the start of a discussion."* That confirms this is a real Application feature, not a gap.
+
+*Future-track candidate: extending the per-file memory with a thin "last-investigation" log per file. A `~/.manual_slop/per_file/<file_id>.md` (file_id by inode, like nagent) that records the last time a discussion referenced this file, the questions asked, and the answers received. This is a Meta-Tooling-friendly addition because it's a plain file.*
+
+---
+
+## 7. Repository history as data
+
+**nagent's claim.** A repo is not only the current tree. History is data too. Transform git history into editing context for a target file. Not vague "retrieval." Explicit transformation of historical artifacts into working input.
+
+**nagent's implementation.** `bin/nagent:file_edit_history_and_summary_block(file_edit_path, ...)`:
+- `git_file_history(repo_root, rel_path)` — `git log --follow --max-count=50` per file
+- `summarize_new_file_commits(...)` — LLM call to one-line-summarize new commits
+- `coedited_file_rows(repo_root, rel_path, commits)` — counts files in the same commits; labels high/medium/low co-edit rate
+- `format_file_history(...)` — produces a `{file-history}` block with editors, step-by-step, co-edited files, summarized commits
+
+**Manual Slop's equivalent (partial).** Manual Slop's `_reread_file_items` (in `ai_client.py`) does mtime-based *current* content re-reading with diff injection as `[SYSTEM: FILES UPDATED]`. It does *not* do git history injection.
+
+The closest things Manual Slop has:
+- **Git commit-linked discussion tracking** in the GUI: each discussion has a "Update Commit" button that stamps `git rev-parse HEAD` (per `docs/guide_gui_2.md` §"Discussions Sub-Menu").
+- **`src/dag_engine.py`** tracks ticket-to-git-commit relationships, but for *MMA* workers, not for the AI's context.
+
+**Verdict.** **PARTIAL.** Manual Slop has current-content diff injection (the easy half) but lacks historical-context injection (the harder half). nagent's `summarize_new_file_commits` would be a useful addition to the Manual Slop AI's context — especially for "explain what this file does" questions where the LLM is meeting the file fresh.
+
+**Domain tag:** Application. *Future-track candidate: a `src/git_history.py` module that mirrors nagent's `file_edit_history_and_summary_block` and is invoked at discussion start (after `aggregate.py`).*
+
+---
+
+## 8. Historical coupling & artifact neighborhoods
+
+**nagent's claim.** A file lives in a neighborhood of related artifacts. Files that change together in git history are hints: tests, headers, config, paired implementation. High co-edit rate means "look here maybe." Not "edit everything."
+
+**nagent's implementation.** `coedited_file_rows(repo_root, rel_path, commits)`:
+- Counts files in the same commits as the target
+- Labels: high (>=50% co-edit), medium (>=20%), low
+- Renders a `| file | commits together | P(other file changed | target file changed) |` table
+- Guidance text: "Use these files as hints. Before editing, inspect high-likelihood co-edited files when the requested change may affect interfaces, tests, config, or paired code. Do not edit them unless the user request or evidence requires it."
+
+**Manual Slop's equivalent.** None. Manual Slop has `py_get_hierarchy` (subclass scan) and `ts_c_*_get_*` AST tools, but **no tool that returns "files that historically co-edit with this file."** The closest is `derive_code_path` (call-graph trace), which is structural not historical.
+
+**Verdict.** **GAP.** This is a real missing tool. nagent's framing — "hints, not commands" — is exactly the right level for a co-edit suggestion. A 50-line tool (`py_coedit_files(path) -> list[(path, count, likelihood)]`) would fill the gap.
+
+**Domain tag:** Application. *Future-track candidate: a `py_coedited_files` MCP tool + `ts_c_coedited_files` for C/C++.*
+
+---
+
+## 9. Disposable sub-conversations
+
+**nagent's claim.** Exploration creates noise. Spawn disposable workers. Sub-conversations are temporary nagent processes with isolated conversations. Their lifetime does not matter. The artifact they return matters.
+
+**nagent's implementation.** `<nagent-conversation>` tag in the main loop's response:
+- Parent appends `<nagent-conversation prompt="...">` to its conversation
+- Parent spawns `nagent --invocation delegated --parent-conversation <name> --json` as a subprocess
+- Child's `--json` output is parsed, rolled up into the parent's `recursive_input_tokens` / `recursive_output_tokens`
+- Child has its own conversation file; no shared context except the explicit prompt
+- Parent gets a concise artifact: the child's `<nagent-response>` content, plus token usage
+
+**Manual Slop's equivalent (corrected per user).** The first draft of this report claimed **PARITY (stronger in some ways)**. The user corrected this:
+
+> *"I don't know if I have disposable sub-conversations, I don't really have them for non-mma runs. I probably want to add that for just 1:1 discussions where I use a sub-agent manually for specific points."*
+
+So the actual picture is:
+
+| Layer | Sub-conversation support |
+|---|---|
+| **MMA Tier 3 / Tier 4** | **Yes.** `mma_exec.py` spawns a real subprocess per ticket with Context Amnesia. `ai_client.reset_session()` at start of `run_worker_lifecycle`. The Ticket output is the "distilled artifact" returned to the parent (`ConductorEngine`). Per the docs: *"Tier 3 worker is a fresh subprocess with a clean context window, receiving only the prompt and the relevant context slice."* |
+| **1:1 main discussion** | **No.** The Application's chat loop has no sub-conversation mechanism. The user types a prompt, the AI responds, the loop continues. There's no way to "ask a sub-agent to investigate X and bring back the answer." |
+
+The user is correct: this is a gap. The MMA pattern is the prototype. A future track could extract `MMA's run_worker_lifecycle` into a reusable `app.spawn_sub_conversation(prompt, allowed_tools=...)` method that the App can call from `pre_tool_callback` or from a new "investigate this" command.
+
+**Verdict.** **PARITY for MMA; GAP for 1:1 discussions.** The MMA pattern is strong. The 1:1 chat has no equivalent. The user explicitly flagged this as a want.
+
+**Domain tag:** Application (and possibly Meta-Tooling). *Future-track candidate: a `src/sub_conversation.py:SubConversationRunner` that the App can call to spawn disposable sub-agents on-demand during 1:1 discussions. Per the user: useful for "specific points" within a longer conversation.*
+
+---
+
+## 10. Controlled writes
+
+**nagent's claim.** A loop that writes files needs explicit boundaries. nagent is a reference implementation with conventions, **not a sandbox**. Shell runs with your permissions. Structured writes are checked. That is not a security boundary. Do not pretend it is.
+
+**nagent's implementation.**
+- `validate_write_path(path, file_edit_path, ...)` — in main mode: path must be in `/tmp`, `/var/tmp`, or `$TMPDIR`. In file-edit mode: path must be the target file (or one of its split segments).
+- Rejected writes append `<nagent-write-result status="error">` to the conversation.
+- `<nagent-shell>` runs whatever the LLM wrote, with the user's permissions, in the user's working directory. **There is no shell sandbox.** This is explicit.
+
+**Manual Slop's equivalent.** Manual Slop has a *much* stronger security model:
+
+| nagent | Manual Slop |
+|---|---|
+| `validate_write_path`: in main mode, path must be in `/tmp`, `/var/tmp`, or `$TMPDIR` | `mcp_client._is_allowed`: in main mode, path must be in the allowlist (constructed from `file_items` + `extra_base_dirs`); history.toml and `*_history.toml` are *always* blocked |
+| `execute_write` writes the file directly | `set_file_slice` / `edit_file` / `py_update_definition` route through AST or string-match for validation |
+| `<nagent-shell>` runs the user's full shell, full permissions, no approval | `run_powershell(script, base_dir, qa_callback=...)` requires GUI modal approval (Execution Clutch), 60s timeout, `taskkill` cleanup, optional Tier 4 QA on failure |
+| No per-tool allowlist | 3-layer security: `configure` (allowlist) → `_is_allowed` (path validation) → `_resolve_and_check` (resolution + symlink resolution) |
+| No sandbox at all | PowerShell-only (no bash/cmd) by default; can be enabled in `[mcp_env.toml]` |
+
+**Verdict.** **PARITY (STRONGER on Manual Slop's side).** Manual Slop's HITL-required shell execution + 3-layer allowlist is *dramatically* more secure than nagent's tmpdir check. The user explicitly chooses "less safety but more flexibility" with nagent, and "more safety but more friction" with Manual Slop.
+
+**Domain tag:** Both. The Application needs Manual Slop's strict model. The Meta-Tooling could legitimately use nagent's looser model *because the human is in the loop* (the bridge script pops a GUI dialog).
+
+---
+
+## 11. Large files as explicit artifacts (split/patch)
+
+**nagent's claim.** Big files exceed context. Split them. Do not pretend they fit. The split is a *data structure* with `index.json` and segment files; the patch is a unified diff; the source hash validates that nothing changed.
+
+**nagent's implementation.**
+
+The 4-file pipeline:
+1. **`nagent-file-split <file> --output <dir> --split <type> [--summarize] [--refresh INDEX] [--target-bytes 32768] [--natural]`**:
+   - `EXTENSION_MAP` covers 11 languages (txt, md, cpp, py, xml, js, ts, json, yaml, go, rs, java)
+   - Per-language `SCORE_BY_TYPE` (no tree-sitter; regex + line-counting + brace/JSON/XML depth counters)
+   - `py_score` rewards blank lines followed by `def`/`class`/`async def`
+   - `cpp_score` uses `brace_depth` to find closing braces at depth 0
+   - `json_score` uses `json_depth` to find closing `}`/`]` at depth 0
+   - Writes `index.json` with `source_path`, `sourcesha256`, `source_size_bytes`, `source_line_count`, `split_type`, `target_bytes`, `natural`, `created_at`, `segment_count`, `segments[]`
+   - Each segment is a separate file with `name-0001.py`, `name-0002.py`, etc.
+   - `--summarize` flag spawns `nagent-file-summarize` per-segment subprocess
+2. **User edits the segment files** (in place, via vim, etc.)
+3. **`nagent-file-patch <index> [--patch PATH] [--dry-run] [--force]`**:
+   - `validate_index(index, require_hash_match=not force)` — **strict** hash check; rejects if source changed
+   - `merge_segments(segments) -> str` — concatenates segment contents in order
+   - `make_unified_patch(source, original, updated)` — `difflib.unified_diff`
+   - Writes the patch file; if `apply=True` and `changed=True`, writes the source
+4. **`nagent-file-summarize <file> [--limit-word-count N] [--output DIR] [--json]`**:
+   - Files > 64 KB cascade to `nagent-file-split --summarize` first
+   - `summarize_content` retries up to `SUMMARY_MAX_ATTEMPTS = 2` if the LLM overshoots the word limit
+   - `combined_summary_from_index` glues per-segment summaries into one
+
+**Manual Slop's equivalent (different mechanism, same insight).** Manual Slop has all the *parts* of nagent's split/patch/summarize, but they live in different files and use different mechanisms:
+
+| nagent | Manual Slop |
+|---|---|
+| `nagent-file-split` with per-language `SCORE_BY_TYPE` (regex + line counts + brace/JSON/XML depth) | `aggregate.py:build_file_items()` + `py_get_skeleton` (tree-sitter) + `ts_c_*_get_skeleton` (tree-sitter) + `outline_tool.py` |
+| `index.json` with `source_path`, `sourcesha256`, `segments[]` | No explicit `index.json`. The "split" is implicit in `_reread_file_items` (mtime-based, not hash-based) and the `py_get_skeleton` tool returns the structural view on demand. |
+| `nagent-file-patch` with strict `validate_index` (hash check) | `set_file_slice` / `edit_file` with `result of file.read_text()` pre-write validation. No hash-based pre-validation. |
+| `nagent-file-summarize` with per-segment LLM call + retry | `run_subagent_summarization(file_path, content, is_code, outline) -> str` (in-process LLM call) |
+| Combined `combined_summary_from_index` | No equivalent; `aggregate.build_markdown_no_history` builds a single markdown per call |
+| `nagent-file-summarize` cascades to `nagent-file-split --summarize` for > 64 KB | `RAGEngine._chunk_code` cascades to chunking for Python (mtime-based invalidation, ChromaDB persistence) |
+
+**Crucial difference: Manual Slop uses tree-sitter, nagent does not.** nagent's per-language scoring functions are *all regex-based* (`cpp_score` looks for closing braces at depth 0; `py_score` looks for blank lines followed by `def`/`class` keywords; no AST parsing). Manual Slop's `py_get_skeleton` and `ts_c_*_get_skeleton` use the tree-sitter library for actual AST traversal.
+
+This is a trade-off. Tree-sitter is more accurate but requires a native dependency. nagent's approach works on any Python install with no compiled extensions. For the Application domain, tree-sitter is already a dependency (`file_cache.py`); for the Meta-Tooling, nagent's regex approach has appeal.
+
+**Verdict.** **PARITY (DIFFERENT MECHANISM).** Both have the "split / patch / summarize as explicit data artifacts" insight. nagent uses subprocesses + per-language scoring + hash validation. Manual Slop uses tree-sitter + in-process calls + mtime validation. The key safety property — *"the patch operation validates the source hasn't changed"* — is done by nagent via SHA-256; Manual Slop does it implicitly by re-reading the file and string-matching. Manual Slop could adopt the explicit hash approach for stronger guarantees.
+
+**Domain tag:** Both. *Future-track candidate: an explicit `src/split_lib.py` + `src/patch_lib.py` mirroring nagent's design, used by the Application for very-large-file scenarios (e.g., a 200KB legacy C file where skeleton + sig + def aggregation isn't enough).*
+
+---
+
+## 12. Tool discovery (self-describing executables)
+
+**nagent's claim.** Tool capability should be explicit data too. No central registry. Tools describe themselves.
+
+**nagent's implementation.** `bin/helpers/nagent_cli.py:collect_bin_tool_descriptions(bin_dir)`:
+- Iterates every executable in `bin/`
+- Runs each with `--description` (10s timeout per)
+- Captures stdout, parses it
+- Concatenates into a single "Available tools:\n\n<description 1>\n\n<description 2>\n..." block
+- Inserts this block into the initial context
+
+Each tool's `__main__` starts with:
+```python
+def exit_on_description(description: str) -> None:
+    if "--description" in sys.argv:
+        print(description)
+        raise SystemExit(0)
+```
+
+So `nagent-file-split --description` prints "Split a large file into structure-aware segments..." and exits 0. The main `nagent` loop calls `collect_bin_tool_descriptions` once at startup.
+
+**Manual Slop's equivalent.** None. The 45 MCP tools in `src/mcp_client.py` are dispatched by a flat if/elif chain in `dispatch()`:
+```python
+def dispatch(tool_name, tool_input):
+    if tool_name.startswith("bd_"):
+        return _dispatch_beads(tool_name, tool_input)
+    if tool_name == "read_file":
+        return _read_file(tool_input["path"])
+    if tool_name == "py_get_skeleton":
+        return _py_get_skeleton(tool_input["path"])
+    # ... 45+ branches ...
+    return f"ERROR: unknown tool: {tool_name}"
+```
+
+Adding a new tool requires:
+1. Edit `dispatch()` to add the branch
+2. Update the security allowlist in `_resolve_and_check` (if filesystem access)
+3. Update the AI capability declaration in `get_tool_schemas()`
+4. Add tests
+
+nagent's approach: drop an executable in `bin/`, implement `exit_on_description`, done. The tool is auto-discovered.
+
+The user (per the pushback): *"The tool use is kinda upfront, I want to add an intent based dsl to help with 'discovery' or combinatorics but no where near that ideation yet."* — so this is a known want, but low priority.
+
+**Verdict.** **GAP (Application).** nagent's pattern is genuinely better here, but Manual Slop has 45 tools in production and a migration would be a big refactor. The win is real (extensibility) but the cost is also real (rewrite the dispatch layer).
+
+**Domain tag:** Both. For the Meta-Tooling (the `scripts/` directory), nagent's pattern is more aligned with the external-agent usage model. For the Application, the existing `dispatch` if/elif is fine.
+
+*Future-track candidate: a `mcp_architecture_refactor_20260606` (already on the board) would benefit from nagent's pattern. The "sub-MCP" extraction the planned refactor proposes is exactly the right scope for this — each sub-MCP could be its own self-describing module.*
+
+---
+
+## 13. Differences from frameworks
+
+nagent's philosophical frame: framework-style systems hide state in object graphs and long-lived agent abstractions; nagent keeps everything as explicit files. The reframing table at the end of the nagent README is excellent:
+
+| Common term | nagent framing |
+|---|---|
+| memory | editable artifact |
+| retrieval | preserved work / historical context |
+| agent | temporary transformation function |
+| context | explicit input data |
+
+This report's §2-§12 have been showing where Manual Slop *agrees* with nagent's reframings and where it *deliberately diverges*.
+
+**Verdict.** The reframing is useful. The application can pick and choose which reframings to adopt per layer.
+
+**Domain tag:** Both. This is the philosophical lens for the whole report.
+
+---
+
+## 14. Build your own
+
+nagent's last section: *"The minimal system is not mystical. Small loop over explicit state."* The list of 12 buildable steps: `generate_text(file) -> str`, growing conversation document, initial context with the contract, output format + parser, handlers that append results to state, loop after actions, visible retry on malformed output, child loops for delegation, per-artifact memory, repository history → context blocks, split/index/patch for large files, save/load/edit/summarize for memory maintenance.
+
+**Verdict.** Manual Slop *has* all 12 of these. Just in different files, with different names, and at a different scale.
+
+**Domain tag:** Both. The 12-step list is a useful checklist for any future LLM-application track.
+
+---
+
+## 15. The 6 Pitfalls (Revised from 8, after User Corrections)
+
+The first draft of this report had 8 pitfalls. The user-corrections on §3 and §6 collapsed 2 of them. The remaining 6:
+
+### Pitfall 1: No structured output protocol in the Application AI
+
+The Application uses opaque provider-native function calling. The user can read the conversation, but cannot read a `tool_call` from the comms log without knowing the provider's schema. nagent's regex-tag protocol is more debuggable for the Meta-Tooling. **Decision: not a problem for the Application (provider-native is the right choice). Worth borrowing for the Meta-Tooling.** **Domain tag:** Both. *Future-track candidate: an intent-based DSL for Meta-Tooling agent calls.*
+
+### Pitfall 2: Provider-specific history is in process globals
+
+`src/ai_client.py` has `_anthropic_history`, `_deepseek_history`, `_minimax_history` — 3 separate per-provider history lists, each with their own lock. Switching providers mid-session loses history. nagent's "single conversation file" model is provider-agnostic.
+
+**Concrete change:** A future refactor toward a stateless `LLMClient` class with an explicit `Conversation` object (the transcript as a `list[Message]`) would let:
+- Users save/load/replay conversations
+- Provider switching doesn't lose history
+- Tier 4 QA and Tier 3 workers share a common conversation format
+
+**Domain tag:** Application. *Future-track candidate: a `src/conversation.py:Conversation` dataclass + `src/llm_client.py:LLMClient` stateless wrapper around the 5 providers.*
+
+### Pitfall 3: RAG is not "history as data"
+
+Manual Slop's RAG (`src/rag_engine.py`) is fuzzy and not auditable. nagent's git-history-driven context is exact and inspectable. RAG is useful but should be **additive**, not a replacement. The Application's `_reread_file_items` mtime-based diff injection is the "history as data" mechanism Manual Slop already has.
+
+**The user's clarification:** *"RAG is an optional thing, doesn't have to be used. Would be cool to have a sub agent maybe prepare a rag chunks before I use them in a run."*
+
+**Decision:** RAG stays. The user wants a *staging* workflow: a sub-agent prepares RAG chunks before a run, the chunks become the discussion's starting memory. This is consistent with the nagent-inspired sub-conversation pattern (§9).
+
+**Domain tag:** Application. *Future-track candidate: a "RAG pre-staging" sub-conversation runner that pre-builds the index for a planned run.*
+
+### Pitfall 4: The AI client is a stateful singleton with module-level globals
+
+2,685-line `src/ai_client.py`. The module is the abstraction layer. To import it for testing, you trigger 5 provider SDKs' lazy imports. The unit tests are the only way to know what state is in flight.
+
+This is the *opposite* of nagent's "files are the system; the process is a worker." nagent's `run_agent_loop` is 50 lines, stateless, testable. A future refactor toward a stateless `LLMClient` class would make `ai_client` parseable, testable, and saveable.
+
+**Domain tag:** Application. *Future-track candidate: a `src/llm_client.py:LLMClient` class with explicit `Conversation`, `Provider`, `History` objects. Backwards-compatible with the current `ai_client.send()` API.*
+
+### Pitfall 5: No non-MMA disposable sub-conversations
+
+The MMA pattern is strong. The 1:1 chat has no equivalent. The user *explicitly* flagged this as a want: *"I probably want to add that for just 1:1 discussions where I use a sub-agent manually for specific points."*
+
+**Decision:** Design `src/sub_conversation.py:SubConversationRunner` that the App can call to spawn disposable sub-agents on-demand during 1:1 discussions. Reuse MMA's subprocess pattern (`mma_exec.py` as the template). The sub-agent returns a concise artifact to the parent (nagent's pattern). Useful for "investigate this file" / "summarize this concept" / "look up this API" commands.
+
+**Domain tag:** Application. *Future-track candidate: a `src/sub_conversation.py` + a GUI "Investigate…" button on the message panel.*
+
+### Pitfall 6: Hard-coded tool discovery
+
+The 45 MCP tools in `mcp_client.py:dispatch` are in a flat if/elif chain. nagent's `--description` self-describing executable pattern is more extensible.
+
+**The user's position:** *"The tool use is kinda upfront, I want to add an intent based dsl to help with 'discovery' or combinatorics but no where near that ideation yet."*
+
+**Decision:** Low priority. The `mcp_architecture_refactor_20260606` (already on the board) is the natural place to address this — sub-MCPs as self-describing modules.
+
+**Domain tag:** Both. *Future-track candidate: subsumed by mcp_architecture_refactor_20260606.*
+
+### Pitfalls removed by user-corrections
+
+- **(removed)** Pitfall about "Conversation state is buried in module-level globals" — overstated. Manual Slop has editable UI state (Takes, UISnapshot, ContextPreset); it lacks editable *raw transcripts*, but that's a *different* design choice, not a gap. (See §3.)
+- **(removed)** Pitfall about "per-file memory" — overstated. Manual Slop *does* have per-file memory in the curation dimension; what's missing is nagent's conversation-log dimension, which is a different optimization. (See §6.)
+

+## 16. Recommended reading path for engineers
+
+If you haven't read nagent, here's the priority:
+
+1. **The README's first 3 sections** ("What It Looks Like", "Durable Work", "Text In Text Out") — the philosophy in 5 minutes.
+2. **`bin/nagent:run_agent_loop()`** — the actual loop, 50 lines.
+3. **`bin/helpers/nagent_file_split_lib.py:SCORE_BY_TYPE`** — the per-language scoring; shows what "structure-aware" can mean without tree-sitter.
+4. **`bin/helpers/nagent_file_patch_lib.py:validate_index`** — the strict hash check; the safety property of nagent's split/patch workflow.
+5. **`bin/helpers/nagent_file_summarize_lib.py:summarize_content`** — the retry-with-smaller-prompt pattern.
+6. **`bin/helpers/nagent_cli.py:collect_bin_tool_descriptions`** — the tool-discovery pattern; 30 lines.
+
+The README's 14 sections can be skimmed in 15 minutes if you have the context this report provides. Read in order 1-5 above for the implementation depth.

+# Track: Mike Acton's nagent — Deep Dive on LLM Agent Architecture
+
+**Status:** Active (spec approved 2026-06-08; revised 2026-06-08 with user-corrections)
+**Initialized:** 2026-06-08
+**Owner:** Tier 2 Tech Lead
+**Priority:** Medium (architectural; informs future Application+Meta-Tooling decisions but is not a code refactor)
+
+> **Revision note (2026-06-08):** This spec was revised based on direct user corrections after the first draft. Earlier versions overstated gaps in Manual Slop's "editable discussion" and "per-file memory" features; the corrections are folded into §2 and §4 below. Read the **report.md** for the actual analysis; this spec.md is the wrapper.
+
+---
+
+## 1. Overview
+
+This track documents a deep-dive analysis of Mike Acton's [`macton/nagent`](https://github.com/macton/nagent) reference implementation ("nagent" = "not-an-agent") and its implications for how Manual Slop should think about LLM-driven workflows.
+
+nagent is a 14-section, ~1,500-line Python reference that operationalizes the philosophy **"the agent is not the thing; the data is the thing."** It provides a concrete, minimal counterpoint to the standard "agent framework" model. Its central claim: **durable work matters more than durable processes; explicit artifacts beat opaque state.**
+
+The companion doc ([report.md](./report.md)) is the deep-dive analysis itself — a 14-section comparison against Manual Slop's actual implementation, written for engineers (not marketing). This spec.md is the conductor/track wrapper: the design intent, the relationship to the Application vs Meta-Tooling split, the planned follow-up tracks, and the out-of-scope notes.
+
+### 1.1 What this track produces
+
+| Artifact | Purpose |
+|---|---|
+| `spec.md` | This file — the track design and scoping. |
+| `report.md` | The 14-section deep-dive analysis. The primary deliverable. |
+| `comparison_table.md` | A flat side-by-side table (one row per nagent principle) for quick reference. |
+| `decisions.md` | Future-track candidates extracted from the analysis (each becomes a follow-up track if approved). |
+
+### 1.2 Non-Goals
+
+- **Not** rewriting Manual Slop to use nagent. The architectures serve different domains (see §2).
+- **Not** replacing any existing track. This is a *reference* track — it informs future tracks but doesn't compete with them.
+- **Not** a comparison of "framework vs framework." nagent is a 1,500-line reference; Manual Slop is 13,000+ lines of production code with a real GUI, real persistence, real HITL. The comparison is *philosophical*, not "which is better."
+
+---
+
+## 2. The Application / Meta-Tooling Distinction (load-bearing context)
+
+Per `docs/guide_meta_boundary.md`, Manual Slop lives in two distinct architectural domains. **This distinction is critical for understanding the nagent comparison:**
+
+| Domain | Lives at | AI / HITL Model | Tooling |
+|---|---|---|---|
+| **The Application** (`manual_slop`) | `gui_2.py`, `ai_client.py`, `multi_agent_conductor.py`, `dag_engine.py` | A local GUI for orchestrating AI. The "Application AI" is a long-lived assistant that the user talks to over many turns. Strict HITL: every destructive action requires a GUI modal approval. | `manual_slop.toml [agent.tools]` — strict allowlist |
+| **The Meta-Tooling** (us) | `scripts/mma_exec.py`, `conductor/`, `.agents/skills/`, the MCP tools in `mcp_client.py` when used by external agents | External agents (Gemini CLI, OpenCode, Claude Code) that *build* the Application. Each invocation is a fresh sub-agent. Token-firewalled. | Full mcp_client.py toolset, including mutation tools |
+
+**nagent lives in the Meta-Tooling domain.** nagent is a reference for how *external* agents (the ones reading this conversation, the ones writing the code) should structure their own work.
+
+**Manual Slop's Application AI does not — and should not — look like nagent.** The Application AI is a chatty, conversational, persona-driven, RAG-augmented, curation-rich assistant with a real GUI. It's a *different kind of thing*. Conflating the two is exactly the kind of "feature bleed" `guide_meta_boundary.md` warns against.
+
+Every recommendation in `report.md` is qualified with which domain it applies to. The Application is the production code the user cares about; the Meta-Tooling is what we (the agents) use to build it.
+
+---
+
+## 3. Summary of the 14-Section Comparison
+
+The full table is in `comparison_table.md`. Verdict summary:
+
+| nagent Principle | Manual Slop Equivalent | Verdict |
+|---|---|---|
+| 1. Durable work, disposable workers | AppState snapshots + history branching (Takes); MMA workers are real subprocesses | **PARTIAL** — different domains; MMA has it, App doesn't need it |
+| 2. Text in, text out | `ai_client.send()` returns `str`; `mcp_client.dispatch` returns `str` | **PARITY** |
+| 3. Conversations are editable state | Discussion takes + branching + edit-in-place + UISnapshot history; `ContextPreset` for per-file view-mode memory | **PARITY (DIFFERENT FOCUS)** — Manual Slop has this; focuses on *editable UI state* (per Take) and *editable per-file curation* (per FileItem), not editable conversation logs |
+| 4. Visible output protocol | Uses provider-native function calling; the protocol is opaque to humans | **ARCHITECTURAL DIFFERENCE** — Application-side; correct trade-off |
+| 5. The loop (append, call, parse, act, repeat) | `ai_client._send_*` tool-call loop, MMA `ConductorEngine.run`, `WorkflowSimulator.run_discussion_turn_async` | **PARITY** — but the loop is in multiple files, not as a single small function |
+| 6. Per-file memory (curation, not conversation log) | `FileItem` (path + view_mode + ast_mask + custom_slices); `ContextPreset` (saved set of FileItems); Fuzzy Anchor slices | **MANUAL SLOP IS STRONGER IN THE CURATION DIMENSION**; nagent's "file-edit conversation" pattern (one conversation log per file) is not present |
+| 7. Repository history as data | `_reread_file_items` mtime-based diff injection; `git_commit_file_patch` per-file history summaries; no explicit "neighborhood" computation | **PARITY (PARTIAL)** — diff injection is similar; the "neighborhood" computation is missing |
+| 8. Historical coupling & artifact neighborhoods | n/a (no equivalent) | **GAP** — could be added as a new tool |
+| 9. Disposable sub-conversations | MMA `mma_exec.py` Tier 3 workers are real subprocesses; **non-MMA 1:1 discussions do NOT have disposable sub-conversations yet** (per user) | **GAP (Application) — useful for 1:1 discussions; **PARITY for MMA** |
+| 10. Controlled writes | MCP 3-layer security + Execution Clutch + Allowlist Construction + Path Validation + Resolution Gate | **PARITY (STRONGER)** — Manual Slop's 3-layer is more thorough than nagent's tmpdir check |
+| 11. Large files as explicit artifacts (split/patch) | `nagent-file-split`/`nagent-file-patch`/`nagent-file-summarize` with `index.json` + segment files + source hash validation; 32 KB target size; per-language natural splitters (no tree-sitter) | **PARITY (DIFFERENT MECHANISM)** — both have the insight; nagent uses per-language scoring functions + subprocess isolation, Manual Slop uses tree-sitter + in-process `summarize.py` |
+| 12. Tool discovery (self-describing executables) | Hard-coded `dispatch` if/elif chain in `mcp_client.py` | **GAP (Application) — could be added; useful for the Meta-Tooling domain** |
+| 13. Differences from frameworks | The philosophical frame | n/a |
+| 14. Build your own | The reference's "minimal" claim is wrong for the Application | n/a for Application |
+
+The full 14-row analysis with 6 (revised from 8) specific Manual Slop pitfalls is in `report.md`.
+
+---
+
+## 4. The Revised 6 Pitfalls (corrected)
+
+Earlier versions of this list contained two errors that user-corrections caught:
+
+- **REMOVED** pitfall #3 (per "Conversation state is buried in module-level globals" was over-stated) — Manual Slop has *some* editable-state infrastructure (`HistoryManager` with UISnapshot, discussion Takes/branching, `ContextPreset` save/load) but the actual *raw conversation transcript* is in `ai_client._provider_specific_history` globals. The truth is: **Manual Slop has editable UI state, not editable conversation transcripts.** That distinction is now captured honestly in §3 of the report.
+
+- **REVISED** pitfall #6 (per "Per-file memory") — Manual Slop *does* have a per-file memory concept (`FileItem` + `ContextPreset` + `custom_slices` + `ast_mask`), but it's *curation memory*, not nagent's *conversation-log memory*. Manual Slop's concept is *richer in the curation dimension* but *absent in the conversation-log dimension*. That's a useful distinction.
+
+The remaining 6 pitfalls, after corrections:
+
+1. **No structured output protocol** in the Application AI (uses opaque function calling; nagent's regex tag protocol is the alternative for the Meta-Tooling). **Domain: Application can stay opaque; Meta-Tooling should learn.**
+2. **Provider-specific history is in process globals** (5 separate per-provider lists with their own locks; switching providers mid-session loses history). **Domain: Application. Future-track candidate.**
+3. **RAG is not "history as data"** — RAG retrieval is fuzzy and not auditable. nagent's git-history-driven context is exact and inspectable. RAG is useful but should be additive, not a replacement. **Domain: Application. Coexists with nagent-style history.**
+4. **The AI client is a stateful singleton with module-level globals** (2,685-line `ai_client.py` is unparseable without state). A future refactor toward a stateless `LLMClient` class with explicit `Conversation` objects would let the App save/load/replay conversations as files. **Domain: Application. Future-track candidate.**
+5. **No non-MMA disposable sub-conversations** — only MMA workers are real subprocesses; the user explicitly noted that 1:1 discussions don't have sub-agents. nagent's `<nagent-conversation>` pattern (a sub-agent for bounded investigation) would be valuable for the Application. **Domain: Application. Future-track candidate (user-flagged as a want).**
+6. **Hard-coded tool discovery** — the 45 MCP tools are in a flat if/elif chain in `dispatch`. nagent's `--description` self-describing executables pattern is more extensible. **Domain: both. Low priority.**
+
+Plus 2 domain-domain recommendations that are not pitfalls per se:
+
+- **Personas are config bundling** (per user: "just bundles preparatory cruft — vendor/model, tools/permissions, and system prompts"). The user noted that you can *completely opt out* by just using AI settings directly. **Domain: Application. Keep as-is; not a pitfall.**
+- **RAG is opt-in** (per user: "doesn't have to be used"). Worth considering: a sub-agent that *prepares RAG chunks* before a run. **Domain: Application. Future-track candidate.**
+

+### Related Tracks
+
+- `data_oriented_error_handling_20260606` — Already cites Acton by name. The `Result[T]` + `ErrorInfo` data model from this track is consistent with nagent's "data, not control flow" stance.
+- `qwen_llama_grok_integration_20260606` — The "OpenAI-compatible shared helper" pattern is exactly nagent's "thin boundary adapter on a normalized data structure" approach.
+- `mcp_architecture_refactor_20260606` — Already blocked by `data_oriented_error_handling_20260606`. The sub-MCP extraction (planned) will benefit from nagent's "small helper per concept" decomposition pattern.
+- `data_structure_strengthening_20260606` — The type-alias work is consistent with nagent's "make the data shape explicit" stance. The audit script + NamedTuple work parallels nagent's split-index / patch-artifact approach.
+

+
+- Mike Acton, "Data-Oriented Design and C++" (cppCon 2014) — The original DOD talk that nagent operationalizes
+- Ryan Fleury, "The Easiest Way To Handle Errors Is To Not Have Them" — Companion framework; same "errors as data" thesis
+- Timothy Lottes (@NOTimothyLottes) — Cited in the `data_oriented_error_handling` review; same "error codes are data" stance

+
+## 8. Scope Boundaries
+
+### In Scope
+
+- The 14-section nagent philosophy
+- The 6 (revised) concrete pitfalls in Manual Slop
+- Mapping each pitfall to a future-track candidate (in `decisions.md`)
+- Application vs Meta-Tooling domain classification for every recommendation
+- The philosophical grounding for existing Manual Slop conventions (data-oriented, thread-disciplined, GUI-decoupled)
+
+### Out of Scope
+
+- **Implementation work.** This is a reference/analysis track. No code is being changed.
+- **Replacing nagent in the Meta-Tooling.** The Meta-Tooling is whatever the external agent (Gemini CLI, OpenCode) is. nagent is a *reference example*, not a competitor. It's worth reading for ideas, not adopting wholesale.
+- **Building a new "data-oriented" track for Manual Slop.** The `data_oriented_error_handling_20260606` track already covers the data-vs-control-flow axis. This track is the *philosophical foundation* for that work; the implementation track is separate.
+- **Comparing nagent to other LLM agent frameworks (LangChain, AutoGen, CrewAI, etc.).** nagent is a specific small reference; those are different scales. This track is about nagent specifically.
+
+### Known Trade-offs (called out in the report)
+
+- **Manual Slop's personas are a feature, not a bug, in the Application domain.** A user-facing chatty assistant benefits from "persona = named configuration that the user can save and recall." nagent's "data, not personality" stance is correct for sub-agent invocations but wrong for long-lived assistant sessions. (Per user: personas are config bundling; the user can opt out by using AI settings directly.)
+- **Manual Slop's RAG is a feature, not a bug, in the Application domain.** RAG enables semantic search across large codebases. nagent's "git history → summaries" is exact but doesn't help when the user asks "how does the execution clutch work" and the relevant information is in `guide_architecture.md` (a doc, not source). RAG is opt-in.
+- **Manual Slop's GUI is a feature, not a bug, for its domain.** It enables the rich persona, curation, RAG, and snapshot UX. nagent explicitly has no GUI; the Application explicitly has a GUI. They serve different needs.
+- **The "1,500-line reference" vs "13,000-line production" comparison is not fair.** nagent is a teaching example. Manual Slop is a working tool. The right comparison is "nagent's principles vs Manual Slop's implementation," not "which codebase is better."
+
+---
+
+## 9. Verification Criteria
+
+This is a reference/analysis track. The verification is:
+
+- [ ] `report.md` exists and covers all 14 nagent principles with a Manual Slop assessment for each
+- [ ] `comparison_table.md` exists as a flat side-by-side reference
+- [ ] `decisions.md` exists with future-track candidates (each is a separate conductor track to be specced independently)
+- [ ] Every "Manual Slop could learn from nagent here" recommendation is tagged with the domain (Application / Meta-Tooling / Both)
+- [ ] No code is being modified by this track
+- [ ] The companion doc is read by ≥1 person who is planning a future track (the report.md file is referenced by the relevant future-track specs)
+- [ ] (Post-correction) The report's verdicts on nagent §3 (Conversations are editable state) and §6 (Per-File Memory) are *corrected* per user feedback — the first draft overstated gaps
+
+---
+
+## 10. Status
+
+**Approved 2026-06-08 (initial); revised 2026-06-08 with user corrections.** Ready for human review of `report.md`.
+
+After human review of `report.md`, the `decisions.md` candidates will be evaluated:
+- High-priority items (e.g., stateless `LLMClient` class, non-MMA sub-conversations, RAG pre-staging) → new conductor tracks
+- Medium-priority items (e.g., self-describing MCP tools, conversation file persistence) → research spikes
+- Low-priority items → deferred until a specific Application need surfaces
+
+The current `data_oriented_error_handling_20260606` track and the future `mcp_architecture_refactor_20260606` track are already philosophically aligned with nagent's principles; this track is the *explicit* reference to that alignment.

+# Track: Prior-Session Sepia Tint
+
+**Status:** Active (planning)
+**Initialized:** 2026-06-10
+**Owner:** Tier 2 Tech Lead
+**Priority:** C (UI polish; no functional blocker; complements `multi_themes_20260604` and the 2026-06-05 prior-session work)
+**Parent track (none).** Sibling: `multi_themes_20260604` (added TOML theme loading + per-theme syntax palette mapping).
+**Design doc:** [docs/superpowers/specs/2026-06-10-prior-session-sepia-design.md](../../docs/superpowers/specs/2026-06-10-prior-session-sepia-design.md)
+
+---
+
+## 1. Problem Statement
+
+When a user enters Historical Replay mode (a.k.a. "prior session" view), the current implementation
+uses `theme.get_color("bubble_vendor")` as the background tint at three call sites
+(`src/gui_2.py:1028`, `:3960`, plus the "HISTORICAL VIEW" banners at `:5142` and `:5440`).
+This is **not a dedicated prior-session color slot** — it is a semantic overload of the
+"Vendor API" role's bubble color. Authors of new themes cannot tune the prior-session
+feel without changing the Vendor API bubble.
+
+Beyond the missing dedicated slot, there is no **content-level color grading**: text, markdown,
+and code blocks inside prior-session views render at full saturation in the active palette.
+The "I'm looking at a past session" cue is carried only by the bg tint, not by the content.
+
+**Pre-existing related bug** (surfaced by the user during brainstorming): code blocks rendered
+by `imgui_color_text_edit` (`src/markdown_helper.py:328-340`, `src/gui_2.py:4773-4780`) are **not
+tonemap-aware**. Their colors are loaded from the library's hardcoded palettes (`dark`, `light`,
+`mariana`, `retro_blue`) and never passed through `theme._tone_map()`. The user has called this
+"disappointing" because it defeats the primary purpose of the tonemapper: allowing a light
+theme to be usable on a bright monitor without searing the user's retinas.
+
+### 1.1 Goals (in scope)
+
+- **G1** — Add three new theme slots, per-palette: `prior_session_bg`, `prior_session_tint`, and
+  a per-palette float `prior_session_amount`. Defaults baked into `ThemePalette`
+  (`src/theme_models.py`) and the hardcoded fallback dict (`src/theme_2.py:184-201`).
+- **G2** — Add a runtime state dict `_prior_session_amount: dict[str, float]` in `src/theme_2.py`
+  mirroring `_brightness/_contrast/_gamma` exactly. Expose
+  `get_prior_session_amount(palette) / set_prior_session_amount(palette, val) /
+  reset_prior_session(palette)`.
+- **G3** — Add the pure-function helper `apply_prior_tint(rgba, palette_name)` in
+  `src/theme_2.py`. All math uses **float** (not int) end-to-end per user requirement.
+- **G4** — Replace the 2 hardcoded `bubble_vendor` tint sites in `src/gui_2.py` (lines 1028, 3960)
+  with the new `prior_session_bg` slot, and wrap content-rendering color calls with
+  `apply_prior_tint(...)` at 4 prior-session sites (the 2 "HISTORICAL VIEW" banners plus
+  the comms/tool-log render functions that consume prior-session caches). Audit list in §4.1.
+- **G5** — Add a new "Prior Session Sepia (Per-Palette)" section in the Theme Settings panel
+  (`src/gui_2.py:5007+`) with a single `slider_float` 0.0–1.0 and a "Reset" button. Mirrors
+  the existing Tone Mapping section's behavior: per-palette state, persisted to config, snaps
+  to per-palette default on theme switch.
+- **G6** — Add TOML keys to all 8 existing `themes/*.toml` files with sensible per-theme defaults.
+
+### 1.1.1 Honest constraint: code-block tonemap-awareness is NOT in scope
+
+During spec self-review, the user and I verified the upstream `imgui_bundle 1.92.5` API:
+`TextEditor.get_palette() -> PaletteId` and `TextEditor.set_palette(PaletteId) -> None` where
+`PaletteId` is an enum with 4 hardcoded values (`dark`, `light`, `mariana`, `retro_blue`).
+**There is no `Palette` struct with mutable per-color slots** in this API surface.
+
+The user had hoped this track could fix the pre-existing "code blocks are not tonemap-aware"
+bug. The honest answer is: **the upstream library does not expose a per-instance color
+override API**, so we cannot apply `_tone_map` or `apply_prior_tint` to code-block syntax
+token colors. The same constraint already forced the `multi_themes_20260604` track to ship
+a `syntax_palette` field (one of 4 enums) rather than custom token colors.
+
+What IS tonemap-aware in code blocks today: the bg, selection highlight, current-line fill,
+and line number bg, because those use **ImGui style colors** which go through `get_color()`
+and therefore through `_tone_map`. The four hardcoded syntax token colors
+(`default`/`keyword`/`number`/`string`/`comment`/etc.) are NOT tonemap-aware and CANNOT
+be made so without forking `imgui_bundle`.
+
+This track does NOT fix that. **Out of scope** (see §1.2 N6 and §9 N1). The user should
+not be promised a fix that the API doesn't support.
+
+### 1.2 Non-Goals (out of scope)
+
+- **N1** — Per-language syntax color customization beyond the existing 4 built-in palettes
+  (`dark`, `light`, `mariana`, `retro_blue`). Upstream `imgui_color_text_edit` limitation;
+  deferred per the `multi_themes_20260604` track.
+- **N2** — A "film grain" or "vignette" post-effect to enhance the nostalgic feel. Pure
+  color-grading is sufficient for the "obvious prior session" cue. If the user wants more
+  later, that is a follow-up track.
+- **N3** — Changing the prior-session default to per-theme *config* keys (e.g., users
+  overriding the default per-theme via `config.toml`). The slider value is saved as
+  per-palette state in the same way as brightness/contrast/gamma; the TOML key is the
+  *factory default*, not a user-tweakable value.
+- **N4** — Applying the sepia transform to the **whole window** at scope (iii) of the
+  brainstorming. The user chose scope (ii) ("data + chrome inside prior-session views"),
+  with fallback to (iii) only if (ii) looks bad in manual review. Phase 3 includes a
+  manual smoke test that escalates to (iii) only if needed.
+- **N5** — Moving `_prior_session_amount` into the same config dict as the existing
+  brightness/contrast/gamma state. Use the same persistence mechanism (config flush +
+  `app.save_config()`) but a separate dict so the "per-palette" semantics are explicit.
+
+### 1.3 Design constraint (HARD — from user)
+
+> "Make sure that all math you do is not integer based. I want to have as much accuracy
+> as possible for smooth calculations."
+
+Applied to:
+- `apply_prior_tint(rgba, palette) -> tuple[float, float, float, float]` — float math
+  throughout (desaturation, lerp, alpha pass-through).
+- The slider is `imgui.slider_float`, not `slider_int`. Range 0.0–1.0 inclusive.
+- The `_prior_session_amount` dict stores `float`, not `Decimal` or `int`. Default 0.3.
+- TOML key `prior_session_amount` is a `float`, not an int. Round-trip through
+  `tomllib`/`tomli_w` preserves the float type.
+- `theme_2._tone_map()` is already float; the new transform composes on top of it.
+- `apply_color_grades_to_editor_palette` iterates `Palette` color slots as float
+  quadruples (RGBA in 0.0–1.0).
+
+The only place integer 0-255 RGB appears is the TOML theme files (existing convention).
+That is the input boundary; the math happens entirely in float.
+
+---
+
+## 2. Current State Audit (as of commit `9f895117`)
+
+### 2.1 Already Implemented (DO NOT re-implement)
+
+- **TOML theme loading**: `src/theme_2.py:load_themes_from_disk()` (line 339),
+  `_TOML_PALETTES` / `_TOML_SEMANTIC_CACHE` / `_TOML_COLOUR_CACHE` (lines 64-67),
+  `get_color()` (line 153) which resolves through TOML → dataclass → fallback dict.
+- **ThemePalette dataclass**: `src/theme_models.py:ThemePalette` (line ~86) with
+  `bubble_vendor: tuple[int, int, int] = (65, 55, 30)`. Schema validator at line 119.
+- **Per-palette tonemap state**: `_brightness/_contrast/_gamma: dict[str, float]`
+  (`src/theme_2.py:75-77`), `_get_tm()` accessor (line 84), `set_brightness/contrast/gamma`
+  (lines 91-93), `reset_tone_mapping(palette)` (line 95).
+- **Tonemap UI section**: `src/gui_2.py:5007-5023` — "Tone Mapping (Per-Palette)" header,
+  3 sliders + reset button. Each slider calls `theme.set_X(curr_palette, val)` then
+  `app._flush_to_config(); app.save_config()`.
+- **Prior session state**: `AppController.is_viewing_prior_session: bool` (line 982),
+  `prior_session_entries` (line 983), `cb_exit_prior_session()` (line 2105).
+  `App.is_viewing_prior_session` is exposed via the App→Controller delegate.
+- **Prior session render sites (6 audit-ready call sites)**:
+  - `src/gui_2.py:1027-1028` — `App._gui_func` window_bg wrap.
+  - `src/gui_2.py:3959-3961` — `render_prior_session_view` (dedicated prior view).
+  - `src/gui_2.py:4087-4193` — `render_comms_history_panel` consumes
+    `_comms_log_cache` which is replaced with `prior_session_entries` at line 1560
+    when `is_viewing_prior_session` is True.
+  - `src/gui_2.py:4591+` — `render_tool_calls_panel` consumes `_tool_log_cache`
+    similarly replaced at line 1568.
+  - `src/gui_2.py:5140-5145` — `render_mma_dashboard` "HISTORICAL VIEW" banner.
+  - `src/gui_2.py:5438-5442` — `render_tier_stream_panel` "HISTORICAL VIEW" banner.
+- **TextEditor render sites (2)**:
+  - `src/markdown_helper.py:328-340` — per-code-block editor, `editor.set_palette(p_id)`.
+  - `src/gui_2.py:4773-4780` — text viewer TextEditor.
+- **Syntax palette mapping**: `src/theme_2.py:350-367` `get_syntax_palette_for_theme` and
+  `apply_syntax_palette` use the upstream `ed.TextEditor.PaletteId` enum (4 values).
+  `apply_syntax_palette` is called from `apply()` (line 220, line 278) and on
+  `MarkdownRenderer.__init__` (line 90-91).
+- **8 existing themes**: `themes/10x_dark.toml`, `themes/binks.toml`,
+  `themes/gruvbox_dark.toml`, `themes/monokai.toml`, `themes/moss.toml`,
+  `themes/nord_dark.toml`, `themes/solarized_dark.toml`, `themes/solarized_light.toml`.
+  Each defines a `bubble_vendor` line; none has prior-session slots.
+- **Test infrastructure**: `tests/conftest.py` `live_gui`, `isolate_workspace`,
+  `reset_paths`, `reset_ai_client` fixtures. Puppeteer pattern documented in
+  `docs/guide_simulations.md`.
+
+### 2.2 Gaps to Fill (This Track's Scope)
+
+- **Gap A** — No dedicated prior-session theme slots. The bg is a reuse of `bubble_vendor`.
+- **Gap B** — No content-level color grading. Text/markdown in prior views stays at full
+  palette saturation.
+- **Gap C** — No per-palette runtime control over the prior-session amount. Authors can't
+  tune it without recompiling.
+- **Gap D** — Code blocks (`TextEditor`) are not tonemap-aware (pre-existing). The
+  tonemap slider does not affect syntax-highlighted code. **NOT in scope for this track**
+  — see §1.1.1: the upstream `imgui_bundle 1.92.5` API does not expose per-instance color
+  override for `TextEditor.PaletteId` (the only API is the 4-value enum). Fixing this
+  requires forking the library or writing a custom syntax highlighter, which is a
+  separate track.
+- **Gap E** — No `apply_prior_tint` helper exists. Any future "color grade any
+  ThemeColor" feature would reimplement this from scratch.
+
+---
+
+## 3. Approach: Per-render explicit transform (A1)
+
+The brainstorming design doc (`docs/superpowers/specs/2026-06-10-prior-session-sepia-design.md`)
+records the full rationale. Summary:
+
+- The view layer composes the color transform. `theme.get_color(name)` continues to return
+  the tonemap-graded but non-prior-tinted color. A new `apply_prior_tint(rgba, palette)`
+  helper applies the sepia blend on top. Prior-session render sites wrap their
+  `theme.get_color(...)` calls with `apply_prior_tint(...)` (one-line wrap, ~6 sites).
+- The TextEditor palette fix uses a parallel `apply_color_grades_to_editor_palette(editor,
+  palette_name)` helper that **mutates the per-instance `Palette` struct in-place** and
+  re-applies it via `editor.set_palette(palette_struct)`. This is the only known way to
+  per-instance override the upstream library's hardcoded palette.
+- The per-palette `_prior_session_amount` dict mirrors the existing tonemap dicts
+  (`_brightness`, `_contrast`, `_gamma`) exactly. The same persistence mechanism
+  (`app._flush_to_config(); app.save_config()`) applies.
+
+### 3.1 Why not the alternatives
+
+- **A2 (transparent via `get_color`)** — would auto-apply sepia when
+  `is_viewing_prior_session` is True. Rejected: violates the data-oriented principle
+  ("the view composes"); risks accidentally tinting status indicators that must stay
+  saturated (e.g., the red error dot in `is_thinking`).
+- **A3 (context manager scope)** — would require a `with prior_session_view():`
+  wrapper at every prior-session site. Rejected: more boilerplate than A1 with no
+  benefit.
+
+### 3.2 Float-only math contract
+
+The transform is `result = lerp(desaturate(input), tint_color, amount)`.
+
+- `desaturate(rgba)` — float math: `luma = 0.2126*r + 0.7152*g + 0.0722*b` (BT.709),
+  `return (luma, luma, luma, a)`. All in 0.0–1.0.
+- `lerp(a, b, t)` — float: `a + (b - a) * t` for each channel. The result is in 0.0–1.0.
+- `apply_prior_tint(rgba, palette)` — `return lerp(desaturate(rgba), get_prior_tint(palette),
+  get_prior_session_amount(palette))`. Alpha passed through unchanged.
+- `apply_color_grades_to_editor_palette(editor, palette_name)` — iterates the
+  `Palette` struct's color slots (RGBA float quadruples), calls
+  `_tone_map(slot, palette_name)` first, then conditionally `apply_prior_tint(slot,
+  palette_name)`. Sets the modified `Palette` back via `editor.set_palette(palette)`.
+
+The user can confirm the per-palette amount via `imgui.slider_float("##prior_amt",
+theme.get_prior_session_amount(curr_p), 0.0, 1.0, "%.2f")` with `0.0 <= amount <= 1.0`.
+Default 0.3 (subtle, per user choice).
+
+---
+
+## 4. Functional Requirements
+
+### 4.1 Theme model additions
+
+`src/theme_models.py:ThemePalette` gains 3 fields:
+
+```python
+prior_session_bg:      tuple[int, int, int] = (60, 50, 35)    # dark default
+prior_session_tint:    tuple[int, int, int] = (112, 66, 20)   # classic sepia
+prior_session_amount:  float                = 0.3              # subtle
+```
+
+`src/theme_models.py:ThemeFile.from_dict()` and `to_dict()` (lines 137-157) round-trip
+the new fields. The validator at line 119 enforces `0.0 <= prior_session_amount <= 1.0`
+and 3-tuple RGB bounds.
+
+`src/theme_2.py:184-201` fallback dict gains the 3 keys with the same defaults.
+
+### 4.2 Theme module additions
+
+`src/theme_2.py` gains, in order, after the existing tonemap state (~line 95):
+
+```python
+_prior_session_amount: dict[str, float] = {}
+
+def _get_psa(palette: str, default: float) -> float:
+    return _prior_session_amount.get(palette, default)
+
+def get_prior_session_amount(palette: str) -> float:
+    return _get_psa(palette, 0.3)
+
+def set_prior_session_amount(palette: str, val: float) -> None:
+    val = max(0.0, min(1.0, float(val)))  # clamp + cast
+    _prior_session_amount[palette] = val
+
+def reset_prior_session(palette: str) -> None:
+    _prior_session_amount.pop(palette, None)
+```
+
+### 4.3 Transform helpers
+
+`src/theme_2.py` gains, after the tonemap helpers (~line 110):
+
+```python
+def _desaturate(rgba: tuple[float, float, float, float]) -> tuple[float, float, float, float]:
+    """Convert to grayscale using BT.709 luma. All float math."""
+    r, g, b, a = rgba
+    luma = 0.2126 * r + 0.7152 * g + 0.0722 * b
+    return (luma, luma, luma, a)
+
+def _lerp_rgba(
+    a: tuple[float, float, float, float],
+    b: tuple[float, float, float, float],
+    t: float,
+) -> tuple[float, float, float, float]:
+    """Linear interpolation. All float math; t in [0.0, 1.0]."""
+    t = max(0.0, min(1.0, t))
+    return (
+        a[0] + (b[0] - a[0]) * t,
+        a[1] + (b[1] - a[1]) * t,
+        a[2] + (b[2] - a[2]) * t,
+        a[3] + (b[3] - a[3]) * t,
+    )
+
+def apply_prior_tint(
+    rgba: tuple[float, float, float, float],
+    palette_name: str,
+) -> tuple[float, float, float, float]:
+    """Apply the per-palette prior-session sepia blend to a color.
+
+    result = lerp(desaturate(input), get_prior_tint(palette), get_prior_session_amount(palette))
+    No-op at amount=0.0; pure tint at amount=1.0.
+    """
+    amount = get_prior_session_amount(palette_name)
+    if amount <= 0.0:
+        return rgba
+    tint_rgb = get_color("prior_session_tint")
+    tint = (tint_rgb.x, tint_rgb.y, tint_rgb.z, rgba[3])
+    return _lerp_rgba(_desaturate(rgba), tint, amount)
+
+### 4.4 Call-site wraps in `src/gui_2.py`
+
+The 6 prior-session-affected sites get the following surgical edits:
+
+| Line | Current | New |
+|---|---|---|
+| 1027-1028 | `with imscope.style_color(imgui.Col_.window_bg, theme.get_color("bubble_vendor")):` | `with imscope.style_color(imgui.Col_.window_bg, theme.get_color("prior_session_bg")):` |
+| 3960-3961 | `with imscope.style_color(imgui.Col_.child_bg, theme.get_color("bubble_vendor")):` | `with imscope.style_color(imgui.Col_.child_bg, theme.get_color("prior_session_bg")):` |
+| 5142 | `c = theme.get_color("status_warning") if theme.is_nerv_active() else theme.get_color("status_warning")`<br>`imgui.text_colored(c, "HISTORICAL VIEW - READ ONLY")` | wrap with `apply_prior_tint` per the call-site pattern in §4.3 |
+| 5440 | Same pattern as 5142 | Same |
+| `_render_comms_history_panel` (`4087-4193`) | Comms entries that iterate `log_to_render` (line 4115) | When `app.is_viewing_prior_session` is True, wrap each `theme.get_color()` call (for row text, role badge, etc.) with `apply_prior_tint` |
+| `render_tool_calls_panel` (`4591+`) | Same | Same |
+
+A small helper pair is added to `src/theme_2.py` (next to `apply_prior_tint`) to convert
+`imgui.ImVec4` ↔ float tuple, so the wrap is one expression per call site:
+
+```python
+def _imvec4_to_rgba(v: imgui.ImVec4) -> tuple[float, float, float, float]:
+    return (float(v.x), float(v.y), float(v.z), float(v.w))
+
+def _rgba_to_imvec4(rgba: tuple[float, float, float, float]) -> imgui.ImVec4:
+    return imgui.ImVec4(*rgba)
+```
+
+Call-site pattern (e.g., the line 5142 banner):
+
+```python
+c_raw = theme.get_color("status_warning")
+if app.is_viewing_prior_session:
+    c = _rgba_to_imvec4(apply_prior_tint(_imvec4_to_rgba(c_raw), theme.get_current_palette()))
+else:
+    c = c_raw
+imgui.text_colored(c, "HISTORICAL VIEW - READ ONLY")
+```
+
+### 4.5 Theme Settings panel UI
+
+`src/gui_2.py:5007+` gains a new section after the "Reset Tone Mapping" button:
+
+```python
+imgui.separator()
+imgui.text("Prior Session Sepia (Per-Palette)")
+curr_p = theme.get_current_palette()
+ch_p, p = imgui.slider_float("##ps_amount", theme.get_prior_session_amount(curr_p), 0.0, 1.0, "%.2f")
+if ch_p:
+    theme.set_prior_session_amount(curr_p, p)
+    app._flush_to_config()
+    app.save_config()
+if imgui.button("Reset Prior Session Sepia"):
+    theme.reset_prior_session(curr_p)
+    app._flush_to_config()
+    app.save_config()
+```
+
+Persistence: `_prior_session_amount` is saved to `[theme] prior_session_amount` in
+`config.toml` keyed by palette, mirroring the existing brightness/contrast/gamma keys.
+`load_from_config()` (`src/theme_2.py:319-335`) reads it back on startup.
+
+### 4.7 Theme TOML files
+
+All 8 `themes/*.toml` files gain the 3 new keys. Defaults:
+
+| Theme | prior_session_bg | prior_session_tint | prior_session_amount |
+|---|---:|---:|---:|
+| 10x_dark | (60, 50, 35) | (112, 66, 20) | 0.3 |
+| binks | (235, 220, 190) | (140, 80, 30) | 0.3 |
+| gruvbox_dark | (60, 50, 35) | (112, 66, 20) | 0.3 |
+| monokai | (60, 50, 35) | (112, 66, 20) | 0.3 |
+| moss | (60, 50, 35) | (112, 66, 20) | 0.3 |
+| nord_dark | (60, 50, 35) | (112, 66, 20) | 0.3 |
+| solarized_dark | (60, 50, 35) | (112, 66, 20) | 0.3 |
+| solarized_light | (235, 220, 190) | (140, 80, 30) | 0.3 |
+
+The light themes use a cream bg (235, 220, 190) so the bg is distinct from the
+text-bg and from the Vendor API bubble. The sepia tint on light themes is slightly
+warmer (140, 80, 30) to maintain visible contrast on a light background.
+
+---
+
+## 5. Non-Functional Requirements
+
+- **Performance** — `apply_prior_tint` is a pure function: 3 multiplies + 3 lerps + alpha
+  pass-through per call, all float. At ~6 prior-session call sites × ~10 calls per frame
+  in a 60Hz render, total CPU cost is <50µs/frame. Negligible. (`apply_color_grades_to_editor_palette`
+  is NOT in this track — see §1.1.1.)
+- **Thread safety** — all new module-level state in `theme_2.py` is keyed by `palette: str`
+  and accessed in the render thread (the only thread that calls these helpers). No new
+  threads introduced.
+- **Float precision** — All math is float. No integer truncation, no `int(0.5 * 255)`.
+  Output is `tuple[float, float, float, float]` consumed by `imgui.ImVec4` (which is
+  already float-based). The TOML round-trip for `prior_session_amount: float` is
+  tested in `tests/test_prior_session_toml.py`.
+- **Backward compatibility** — Themes missing the new keys fall back to the defaults in
+  `src/theme_2.py:184-201`. Existing user themes (if any) continue to work; the new
+  keys are optional with sensible defaults.
+- **Hot reload** — Adding a new theme key is not a hot-reload concern (themes are
+  loaded at startup). The new `_prior_session_amount` runtime state is not hot-reloaded
+  (same as the existing tonemap state).
+
+---
+
+## 6. Architecture Reference
+
+- `docs/guide_architecture.md` — Threading model (the helpers run on the render thread).
+- `docs/guide_themes.md` — Theme TOML schema, fallback dict, palette resolution.
+- `docs/guide_testing.md` — `live_gui` fixture, Puppeteer pattern, structural testing
+  contract, audit-script policy.
+- `docs/guide_app_controller.md` — `AppController._settable_fields` /
+  `_gettable_fields` registries (we add `prior_session_amount` to `_settable_fields`
+  if the user wants to inspect/override via the Hook API; otherwise it lives in
+  `theme_2` only).
+- `docs/superpowers/specs/2026-06-10-prior-session-sepia-design.md` — Brainstorm
+  design doc with full rationale for the A1 approach.
+- `conductor/tracks/multi_themes_20260604/spec.md` — Sibling track that established
+  the TOML theme loading and per-theme syntax palette mapping pattern.
+- `conductor/tracks/prior_session_test_harden_20260605/` — Predecessor that
+  refactored `test_prior_session_no_pop_imbalance` to call the narrow
+  `render_prior_session_view` (now a more testable function thanks to that work).
+
+---
+
+## 7. Phases
+
+The track is small enough to ship in 3-4 phases over ~2 days. The TDD Red→Green→Refactor
+discipline applies per the project workflow. Atomic per-task commits. Git notes attached
+to each commit.
+
+### Phase 1: Theme model + state + helpers (Day 1, ~3 hours)
+
+- [ ] T1.1 (Red): `tests/test_prior_session_amount.py` — `get/set/reset_prior_session_amount`
+  with per-palette dict semantics; default 0.3 when key absent; reset removes the key;
+  set clamps to [0.0, 1.0].
+- [ ] T1.2 (Green): add `_prior_session_amount` dict + accessors to `src/theme_2.py`.
+- [ ] T1.3 (Red): `tests/test_prior_session_tint.py` — `apply_prior_tint` math:
+  - At amount=0.0, returns input unchanged.
+  - At amount=1.0, returns pure sepia tint (modulated by input alpha).
+  - Monotonic: amount=0.5 is between amount=0.0 and amount=1.0 outputs (in luma).
+  - All values in [0.0, 1.0] for any input.
+  - Alpha is preserved exactly.
+- [ ] T1.4 (Green): add `_desaturate`, `_lerp_rgba`, `apply_prior_tint` to `src/theme_2.py`.
+  All math is float.
+- [ ] T1.5 (Red): `tests/test_prior_session_toml.py` — round-trip a theme TOML with the
+  3 new keys; verify defaults when keys are missing; verify validation rejects
+  `prior_session_amount < 0.0` or `> 1.0` or non-3-tuple RGB.
+- [ ] T1.6 (Green): add the 3 fields to `ThemePalette` (`src/theme_models.py`); update
+  `from_dict` / `to_dict` / `validator`; add the 3 keys to the fallback dict
+  (`src/theme_2.py:184-201`).
+- [ ] T1.7: Add the 3 keys to all 8 `themes/*.toml` files.
+- [ ] T1.8: Run `scripts/audit_weak_types.py` and `scripts/check_test_toml_paths.py`;
+  confirm no regressions.
+- [ ] T1.9: Commit + git note.
+
+### Phase 2: Call-site wraps (Day 1-2, ~4 hours)
+
+- [ ] T2.1 (Red): `tests/test_prior_session_render.py` — unit test for the helper
+  `_imvec4_to_rgba` / `_rgba_to_imvec4` round-trip.
+- [ ] T2.2 (Green): add the 2 helpers to `src/theme_2.py` (next to `apply_prior_tint`).
+- [ ] T2.3: Refactor `src/gui_2.py:1027-1028` and `:3960-3961` to use
+  `theme.get_color("prior_session_bg")` (replacing `bubble_vendor`).
+- [ ] T2.4: Wrap the 4 "HISTORICAL VIEW" + `_render_comms_history_panel` + `_render_tool_calls_panel`
+  call sites with `apply_prior_tint`. All edits are 1-3 lines per site.
+- [ ] T2.5 (DROPPED): `tests/test_code_block_tonemap.py` — **not applicable.** The helper
+  was dropped per §1.1.1. The test is also dropped.
+- [ ] T2.6 (DROPPED): `apply_color_grades_to_editor_palette` — **not implemented.**
+  See §1.1.1.
+- [ ] T2.7 (DROPPED): TextEditor wrap into markdown_helper.py and gui_2.py — **not done.**
+  See §1.1.1.
+- [ ] T2.8: Commit + git note.
+
+### Phase 3: Theme panel UI + persistence (Day 2, ~2 hours)
+
+- [ ] T3.1: Add the "Prior Session Sepia (Per-Palette)" section to
+  `src/gui_2.py:5007+` per §4.6. Mirrors the existing Tone Mapping section.
+- [ ] T3.2: Wire `app._flush_to_config(); app.save_config()` on change.
+- [ ] T3.3: Update `src/theme_2.py:save_to_config()` (line 301-317) to persist
+  `_prior_session_amount` under `[theme.prior_session_amount.<palette>]` (a nested
+  table mirroring the existing `[theme.tone_mapping.<palette>]` structure on line 312).
+  Example resulting TOML:
+
+  ```toml
+  [theme]
+  palette = "10x Dark"
+
+  [theme.prior_session_amount]
+  "10x Dark" = 0.3
+  ```
+
+  `load_from_config()` (line 319-335) reads it back the same way `_brightness` is
+  read on line 333.
+- [ ] T3.4: Update `src/theme_2.py:load_from_config()` (line 319-335) to read it back.
+- [ ] T3.5 (Red): `tests/test_prior_session_persistence.py` — slider change →
+  `app._flush_to_config(); app.save_config()` → restart (or call `load_from_config`)
+  → state restored.
+- [ ] T3.6 (Green): implement persistence in save/load.
+- [ ] T3.7: Commit + git note.
+
+### Phase 4: Verify + checkpoint (Day 2, ~2 hours)
+
+- [ ] T4.1: Run the full `live_gui` test batch (per the existing
+  `live_gui_test_hardening_20260605` guidance — batch, not isolation). Confirm
+  no regressions in the 273+ existing tests.
+- [ ] T4.2: Run the new tests in `tests/test_prior_session_*.py` and
+  `tests/test_code_block_tonemap.py`. All pass.
+- [ ] T4.3: Manual smoke:
+  - Launch `uv run sloppy.py --enable-test-hooks`.
+  - Open Theme Settings. Find the new "Prior Session Sepia" section. Verify slider
+    snaps to the per-palette default (0.3).
+  - Enter a prior session (`Session Analysis → Open Prior Session`). Verify the
+    "HISTORICAL VIEW" banner is tinted, the prior discussion entries are tinted
+    (subtle sepia), and code blocks within them are also tinted.
+  - Adjust the slider to 0.0 → 1.0. Verify the tint amount scales smoothly (no
+    integer stepping artifacts).
+  - Switch themes (e.g., from `10x Dark` to `Solarized Light`). Verify the slider
+    snaps to the new palette's default.
+  - Quit and restart. Verify the slider value persists.
+  - If the prior-session chrome (banners, button labels) does NOT look "obviously
+    old" at amount=0.3, escalate to scope (iii) per brainstorming Q3 (b) — wrap
+    the entire `_gui_func` window bg with the prior-session tint instead of just
+    the prior-session views. Capture before/after screenshots in
+    `docs/reports/prior_session_sepia_<date>/`.
+- [ ] T4.4: Phase checkpoint commit + git note with full verification report.
+- [ ] T4.5: Update `conductor/tracks.md` with the new track entry (or remove
+  the entry if archival). Add `docs/superpowers/specs/2026-06-10-prior-session-sepia-design.md`
+  to the planning-digest index (no digest exists yet for 2026-06-10; if one is
+  authored later, this spec should be referenced).
+
+---
+
+## 8. Verification Criteria
+
+The track is complete when:
+
+- [ ] All 3 new theme slots (`prior_session_bg`, `prior_session_tint`,
+      `prior_session_amount`) are present in `ThemePalette`, the fallback dict,
+      and all 8 `themes/*.toml` files.
+- [ ] `_prior_session_amount` per-palette dict is implemented with get/set/reset
+      accessors, persists to `config.toml`, restores on next launch.
+- [ ] `apply_prior_tint` passes the math contract: identity at 0.0, pure tint at 1.0,
+      monotonic, alpha-preserved, all-float output, all values in [0.0, 1.0].
+- [ ] All 6 prior-session render sites in `src/gui_2.py` use `prior_session_bg` (not
+      `bubble_vendor`) and content is sepia-tinted via `apply_prior_tint`.
+- [ ] Theme Settings panel has a working "Prior Session Sepia (Per-Palette)" section
+      with a 0.0–1.0 slider and a Reset button.
+- [ ] All new tests pass: `tests/test_prior_session_amount.py`,
+      `tests/test_prior_session_tint.py`, `tests/test_prior_session_toml.py`,
+      `tests/test_prior_session_render.py`,
+      `tests/test_prior_session_persistence.py`. (`tests/test_code_block_tonemap.py`
+      is NOT created — the code-block fix is out of scope per §1.1.1.)
+- [ ] No regressions in the 273+ existing `live_gui` tests (batch-verified per
+      `workflow.md` "Isolated-Pass Verification Fallacy" rule).
+- [ ] Manual smoke confirms the prior-session look is "obviously old" at the
+      default 0.3 amount.
+- [ ] **HONEST DISCLOSURE in the final track report**: the pre-existing "code
+      blocks are not tonemap-aware" bug is NOT fixed by this track. The
+      reason (upstream API constraint) is documented in §1.1.1 and §9.
+- [ ] No diagnostic noise (`sys.stderr.write("[XYZ_DIAG] ...")`) in production
+      code. All instrumentation goes to `tests/artifacts/` log files.
+- [ ] `git restore` / `git checkout --` / `git reset` are NOT used without
+      explicit user permission (HARD BAN per AGENTS.md).
+
+---
+
+## 9. Out of Scope (Definitively)
+
+- **N1** — Per-language syntax color customization beyond the 4 built-in palettes.
+  Upstream limitation; deferred.
+- **N2** — Film grain / vignette / scanline post-effect. Pure color-grading only.
+- **N3** — Per-theme user overrides via `config.toml` (the TOML key is the factory
+  default; the slider is the user-tweakable value).
+- **N4** — Process-isolation of the `apply_prior_tint` helper (it's pure; no need).
+- **N5** — Reorganizing the existing `_brightness/_contrast/_gamma` state into a
+  single dict (out of scope; follow the existing pattern).
+- **N6** — **Code-block tonemap-awareness.** The `imgui_bundle` 1.92.5 API
+  exposes `TextEditor.get_palette() -> PaletteId` (the 4-value enum: `dark`,
+  `light`, `mariana`, `retro_blue`) and `set_palette(PaletteId)`. There is
+  **no `Palette` struct with mutable per-color slots**. Per-instance
+  tonemap/sepia overrides on code-block syntax tokens are NOT possible
+  without forking the library. The pre-existing "code blocks not
+  tonemap-aware" behavior persists. Same constraint as the
+  `multi_themes_20260604` track, which shipped a per-theme `syntax_palette`
+  enum field rather than custom token colors.
+- **N7** — Adding a `prior_session_indicator` color slot to the existing
+  `app_controller.py:1142` Hook API registry. The indicator is binary (on/off);
+  the new color is consumed by render code, not the Hook API.

+> **Coordination with `data_oriented_error_handling_20260606`.** This track is *upstream* of the Fleury-pattern `Result[T]` refactor. The shared helper should return `Result[NormalizedResponse, ErrorInfo]` from day 1 (rather than `NormalizedResponse` and raise `ProviderError` on failure), so the subsequent data_oriented_error_handling track is a small mechanical pass over the new code rather than a second migration. Per nagent_review Pitfall #4 (provider history divergence), the helper is also a natural place to add an `ErrorKind.PROVIDER_HISTORY_DIVERGED_FROM_UI` error case. **Concrete change in code:** `def send_openai_compatible(...) -> Result[NormalizedResponse, ErrorInfo]`. The `Result` type is imported from the new `src/result_types.py` (created by the data_oriented_error_handling track); for this track, the helper can stub it locally as a `Tuple[NormalizedResponse, Optional[ErrorInfo]]` and the data_oriented_error_handling track does the mechanical conversion.

 - **Adding a new OpenAI-compatible vendor** = 50 lines of glue (client init + capability declaration + history storage), not 300 lines of duplicated logic.
 - **Anthropic/Gemini/DeepKeep** stay per-vendor code paths; the data-oriented refactor doesn't apply to them because their unique APIs are not OpenAI-compatible-shaped.

UI elements that depend on capabilities should be *visible/enabled/disabled/hidden* based on the matrix value, but the *behavior* they invoke is unchanged. Concretely:

+- `docs/guide_ai_client.md` — current `ai_client.py` architecture; will be updated in Phase 6 to document the matrix and the shared helper. Specifically: the per-provider history globals (`_anthropic_history`, `_deepseek_history`, `_minimax_history`) documented at lines 123-132 are the **state-management shape** that the new 3 vendors should follow in Phase 2/3. (Per `guide_state_lifecycle.md §4`, the per-provider lock pattern is the established convention.)
-- `docs/guide_models.md` — current PROVIDERS constant and provider metadata; will be updated in Phase 6.
+- `docs/guide_models.md` — current PROVIDERS constant and provider metadata; will be updated in Phase 6. Per `docs/guide_models.md §"Data Models"`, the FileItem schema (line 510) is the model layer the capability matrix composes with, not replaces.

The new provider adapters' "build file items" stage should compose with `aggregate.build_file_items()` and the 7 `view_mode` values, not introduce a parallel aggregation path.

+# Test Batching — Post-Refactor Polish Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Polish the test batching orchestrator and live_gui fixture AFTER `test_batching_refactor_20260606` ships. Deliver: (1) shared `_extract_failed_files` library used by both the legacy and new orchestrators, (2) per-file failure list in the new orchestrator's SUMMARY, (3) `live_gui` subprocess window foregrounding, (4) `focus_test_panel` helper wired into 3 starter sims, (5) `tests/artifacts/` scratch cleanup.
+
+**Architecture:** New `scripts/test_failure_parser.py` module (str-ops-only FAILED-line parser, no regex). New module-level functions in `tests/conftest.py` (lazy-import `win32gui`, `ApiHookClient`). Surgical edits to the post-refactor `scripts/run_tests_batched.py:_run_batch` to wire the parser into the SUMMARY. No new files in `src/`.
+
+**Tech Stack:** Python 3.11+ (stdlib `subprocess`, `os`, `sys`, `time`). `pywin32` (already a project dep; used lazily). `ApiHookClient` (existing).
+
+**Blocked by:** `test_batching_refactor_20260606` (must be SHIPPED — this plan reads from the new orchestrator's `_run_batch` and the legacy's `_extract_failed_files`).
+
+**Parent track:** None. **Child tracks:** None.
+
+---
+
+## Constraints (re-stated from the user's standing rules)
+
+- **Do NOT use the native `edit` tool on `.py` files.** It destroys 1-space indentation. Use `manual-slop_edit_file` (exact match), `manual-slop_set_file_slice` (single-line surgical only), or `manual-slop_py_update_definition` (function rewrites).
+- **Do NOT use `git restore`, `git checkout -- <file>`, or `git reset` without explicit user permission in the same message.** HARD BAN.
+- **Do NOT commit `config.toml`, `project.toml`, `project_history.toml`, or repo-root `manualslop_layout.ini`.** These are the user's. Stage and commit only the files listed in each task.
+- **Do NOT add `re` (regex) to the failure parser.** Use `str.startswith`, `str.find`, `str.split`, `str.replace`. Verify with `grep -n "import re\|from re" scripts/test_failure_parser.py` returning empty after Phase 1.
+- **1-space indentation for all Python code.** 2-space for class bodies. 0 leading spaces for module-level. CRLF line endings on Windows.
+- **Do NOT add inline comments to source code.** Docstrings are fine; `#` comments are not.
+- **Type hints required** for all new functions.
+
+---
+
+## Phase 1: Shared `_extract_failed_files` library
+
+Focus: Extract the FAILED-line parser to a shared module that both the legacy and new orchestrators can import. Str-ops-only contract, no regex, with comprehensive unit tests.
+
+**Files:**
+- Create: `scripts/test_failure_parser.py` (~35 lines)
+- Create: `tests/test_test_failure_parser.py` (~120 lines; 11 unit tests)
+- Modify: `scripts/run_tests_batched.py` (the post-refactor new orchestrator; if the legacy is still present and has a local copy, also update it)
+
+### Task 1.1: Red — add 11 unit tests for the shared parser
+
+**Files:** Create `tests/test_test_failure_parser.py`.
+
+- [ ] **Step 1: Write the failing test file**
+
+```python
+"""
+Unit tests for the FAILED-line parser in scripts/test_failure_parser.py.
+Shared by both the legacy run_tests_batched.py and the new orchestrator.
+Str-ops-only contract; no regex.

+
+```python
+"""
+Shared FAILED-line parser for pytest output.
+
+Used by both scripts/run_tests_batched.py (the legacy and the new
+post-refactor orchestrator). Str-ops-only by design: no regex import
+per AGENTS.md standing ban across the codebase.
+
+Contract:
+  - Input: full captured stdout+stderr from a pytest invocation.
+  - Lines that begin with the literal 7-character prefix "FAILED "
+    (note the trailing space) are parsed for the test ID.
+  - The test ID portion ends at the first " - " (space-dash-space)
+    separator that introduces the error message.
+  - If the test ID contains "::", the file path is everything before
+    the first "::". Otherwise the test ID IS the file path.
+  - Backslashes are normalized to forward slashes (Windows safety).
+  - A leading "tests/" prefix is stripped so returned strings match
+    the bare filenames in the test file list.
+  - Returns the unique file paths in first-occurrence order.
+
+Lines that merely contain the substring "failed" (e.g. the
+"1 failed, 2 passed" summary footer) are NOT parsed.

+
+### Task 1.3: Wire the shared parser into the post-refactor orchestrator
+
+**Files:** Modify `scripts/run_tests_batched.py` (the new orchestrator from the refactor's Phase 3).
+
+This task assumes the refactor's Phase 3 is SHIPPED. The new orchestrator's `_run_batch` is at the section documented in the refactor's plan.md around line 1295-1308:
+```python
+def _run_batch(b: Batch, durations: dict[str, float]) -> tuple[int, float, dict[str, float]]:
+ if b.skip_reason:
+  return 0, 0.0, {}
+ cmd = ["uv", "run", "pytest", "-v", "--durations=0"] + b.pytest_args + [str(f) for f in b.files]
+ print(f"\n>>> Running {b.label} ({len(b.files)} files)")
+ t0 = time.monotonic()
+ proc = subprocess.run(cmd, capture_output=True, text=True)
+ elapsed = time.monotonic() - t0
+ new_durs = _parse_durations_from_pytest_output(proc.stdout)
+ print(proc.stdout[-2000:] if proc.returncode != 0 else f"<<< {b.label} PASS in {elapsed:.1f}s")
+ if proc.returncode != 0:
+  print(f"<<< {b.label} FAIL (exit {proc.returncode}) in {elapsed:.1f}s")
+ print(proc.stderr[-1000:])
+ return proc.returncode, elapsed, new_durs
+```
+
+- [ ] **Step 1: Add the import at the top of the new orchestrator**
+
+Read the current top of `scripts/run_tests_batched.py` (post-refactor) to identify the import block. Add:
+
+```python
+from scripts.test_failure_parser import extract_failed_files
+```
+
+- [ ] **Step 2: Refactor `_run_batch` to capture and surface per-file failure lists**
+
+Replace `_run_batch` with a version that:
+- Returns a `tuple[int, float, dict[str, float], list[str]]` (4-tuple; the 4th element is the per-file failure list)
+- On `returncode != 0`, calls `extract_failed_files(proc.stdout + "\n" + proc.stderr)` to get the actual failed files
+- On `subprocess.TimeoutExpired` (raised when the batch exceeds `--timeout` if the caller wraps with a timeout), fall back to all files in the batch with a `(timeout)` annotation
+- Returns `[]` for skipped batches or successful runs
+
+```python
+def _run_batch(
+ b: Batch,
+ durations: dict[str, float],
+ timeout: int | None = None,
+) -> tuple[int, float, dict[str, float], list[tuple[str, str]]]:
+ if b.skip_reason:
+  return 0, 0.0, {}, []
+ cmd = ["uv", "run", "pytest", "-v", "--durations=0"] + b.pytest_args + [str(f) for f in b.files]
+ print(f"\n>>> Running {b.label} ({len(b.files)} files)")
+ t0 = time.monotonic()
+ failed: list[tuple[str, str]] = []
+ try:
+  proc = subprocess.run(
+   cmd,
+   capture_output=True,
+   text=True,
+   timeout=timeout,
+  )
+  elapsed = time.monotonic() - t0
+  new_durs = _parse_durations_from_pytest_output(proc.stdout)
+  if proc.returncode == 0:
+   print(f"<<< {b.label} PASS in {elapsed:.1f}s")
+  else:
+   actual: list[str] = extract_failed_files(proc.stdout + "\n" + proc.stderr)
+   if actual:
+    for f in actual:
+     failed.append((f, ""))
+    print(f"<<< {b.label} FAIL (exit {proc.returncode}) in {elapsed:.1f}s; {len(actual)} actually-failed file(s)")
+   else:
+    for f in b.files:
+     failed.append((str(f), "(no FAILED lines; treating as batch failure)"))
+    print(f"<<< {b.label} FAIL (exit {proc.returncode}) in {elapsed:.1f}s; no FAILED lines found, listing whole batch")
+  return proc.returncode, elapsed, new_durs, failed
+ except subprocess.TimeoutExpired:
+  elapsed = time.monotonic() - t0
+  for f in b.files:
+   failed.append((str(f), "(timeout)"))
+  print(f"<<< {b.label} TIMED OUT after {elapsed:.1f}s (limit {timeout}s)")
+  return 1, elapsed, {}, failed
+```
+
+- [ ] **Step 3: Update `_print_summary` to display the per-file failure list**
+
+The refactor's `_print_summary` takes `results: list[tuple[Batch, int, float]]` (3-tuple). Update to 4-tuple and add the per-file listing:
+
+```python
+def _print_summary(results: list[tuple[Batch, int, float, list[tuple[str, str]]]]) -> int:
+ print("\n" + "=" * 60)
+ print("SUMMARY")
+ print("=" * 60)
+ worst: int = 0
+ any_failed: bool = False
+ for b, code, elapsed, failed in results:
+  if b.skip_reason:
+   status: str = "SKIPPED"
+  elif code == 0:
+   status = "PASS"
+  else:
+   status = "FAIL"
+   any_failed = True
+  worst = max(worst, code)
+  n: int = len(b.files)
+  print(f"[{b.tier}] {b.label:40s} {status:8s} {n} files {elapsed:6.1f}s")
+  for f, note in failed:
+   suffix: str = f"  {note}" if note else ""
+   print(f"   - {f}{suffix}")
+ return 1 if any_failed else worst
+```
+
+- [ ] **Step 4: Update the `main()` callsite to thread the 4-tuple through**
+
+Find the loop in `main()` that calls `_run_batch` and accumulates results. Change the tuple unpacking from 3-tuple to 4-tuple and pass the `failed` list to `_print_summary`.
+
+Before:
+```python
+for b in batches:
+ code, elapsed, new_durs = _run_batch(b, merged_durations)
+ results.append((b, code, elapsed))
+```
+
+After:
+```python
+timeout_arg: int | None = options.timeout
+for b in batches:
+ code, elapsed, new_durs, failed = _run_batch(b, merged_durations, timeout=timeout_arg)
+ results.append((b, code, elapsed, failed))
+```
+
+Also add a `--timeout` argument to the `argparse.ArgumentParser` in `main()` (the refactor's spec doesn't have one; default 600s = 10 minutes per batch):
+
+```python
+p.add_argument("--timeout", type=int, default=600, help="seconds per batch (default: 600)")
+```
+
+- [ ] **Step 5: Verify the script still parses and the new tests pass**
+
+Run: `uv run pytest tests/test_test_failure_parser.py -v`
+Expected: 11/11 PASS.
+
+Run: `uv run python scripts/run_tests_batched.py --plan --tiers 1 2>&1 | head -20`
+Expected: prints tier-1 batches (no execution; just plan output).
+
+- [ ] **Step 6: Run a small tier-1 batch end-to-end to confirm the new path works**
+
+Run: `uv run python scripts/run_tests_batched.py --tiers 1 --no-xdist 2>&1 | tail -30`
+Expected: runs the unit tier; SUMMARY table printed; if any tests fail, the per-file failure list is shown under the failing tier.
+
+- [ ] **Step 7: Commit the integration**
+
+```powershell
+git add scripts/run_tests_batched.py
+git commit -m "feat(orchestrator): wire shared failure parser into _run_batch; per-file SUMMARY"
+```
+
+### Task 1.4: Conductor — User Manual Verification (Phase 1)

+
+  Run: `uv run pytest tests/test_test_failure_parser.py -v`
+  Expected: 11/11 PASS.
+
+- [ ] **Step 2: Run a small tier with a deliberate failure to confirm end-to-end**
+
+  Create a temporary failing test:
+  ```python
+  # tests/test_zzz_fake_failure.py
+  def test_zzz_fake_failure():
+      assert False, "intentional failure"
+  ```
+
+  Run: `uv run python scripts/run_tests_batched.py --tiers 1 --no-xdist 2>&1 | tail -30`
+  Expected: SUMMARY shows the tier failed, the per-file listing shows `test_zzz_fake_failure.py`. Then delete the temp file.
+
+  If the run fails: capture the output to a log file and spawn a Tier 4 QA agent. Do not attempt more than 2 fix cycles; if still failing, report and stop.
+
+- [ ] **Step 3: PAUSE and present verification result**
+
+  > "Phase 1 verification: 11/11 unit tests pass; end-to-end run on tier 1 with a deliberate failure shows the file in the per-file listing. Ready to commit Phase 1 checkpoint and move to Phase 2? (yes / changes needed)"

+- [ ] **Step 4: Create the Phase 1 checkpoint**
+
+  Capture the most recent commit hash. Attach a git note. Update `plan.md` Phase 1 status to `[x]` and append the hash.
+

+Insert one line right after the Popen block (after `proc` is assigned, before any subsequent `wait` / `health` check):
+
+```python
+_foreground_subprocess_window(proc.pid)
+```
+
+Anchor the edit on a unique surrounding context (e.g. the line right after Popen completes — typically a `print` line about spawning, or a `health check` call). Use `manual-slop_edit_file` with the exact `old_string`/`new_string`.

+```
+
+### Task 3.3: Conductor — User Manual Verification (Phase 3)
+
+- [ ] **Step 1: Run the 3 modified sim tests**
+
+  Run: `uv run pytest tests/test_command_palette_sim.py tests/test_workflow_sim.py tests/test_undo_redo_sim.py -v`
+  Expected: all pass.
+
+- [ ] **Step 2: PAUSE and present verification result**
+
+  > "Phase 3 verification: 3 sim tests pass with focus_test_panel calls. The helper is exported and idempotent. Ready to commit Phase 3 checkpoint and move to Phase 4? (yes / changes needed)"
+
+- [ ] **Step 3: Create the Phase 3 checkpoint**
+
+  Capture the most recent commit hash. Attach a git note. Update `plan.md` Phase 3 status to `[x]` and append the hash.
+
+---
+
+## Phase 4: `tests/artifacts/` Scratch Cleanup
+
+Focus: Verify the candidate scratch files have NO references in the codebase, then delete them. Single atomic commit.
+
+**Files:** Delete only; no modifications.
+
+### Task 4.1: Verify and delete scratch files
+
+- [ ] **Step 1: Build the candidate list and verify each is unreferenced**
+
+  The candidate list (per spec §4.4 FR-19):
+  - `test_parser.py`, `test_patterns.py`, `test_regex.py`
+  - `verify_layout.py`, `check_cwd.py`, `check_cwd_uv.py`, `exists.py`, `fix_stale_names.py`, `fix_conftest_layout.py`
+  - `fake_test_output.txt`
+  - `agents_skip_msg.txt`, `commit_layout_diag_msg.txt`, `configpath_msg.txt`, `context_presets_msg.txt`, `hooks_dictkey_msg.txt`, `reset_layout_msg.txt`, `st2a_prompt.txt`, `st2a_task.toml`, `st2g_msg.txt`, `st2g_msg2.txt`, `st2g_msg3.txt`, `stale_test_msg.txt`, `synthesis_crash_msg.txt`, `warmup_fix_msg.txt`, `workflow_skip_msg.txt`
+  - `task1.toml`, `task1.txt`, `task2.toml`, `task2_1.txt`, `task3.toml`, `task3_1.txt`, `task4.toml`, `task_1_1.txt`
+  - `temp_config.toml`, `temp_data.txt`, `temp_liveaisettingssim.toml`, `temp_livecontextsim.toml`, `temp_liveexecutionsim.toml`, `temp_livetoolssim.toml`, `temp_notes.txt`, `temp_project.toml`, `temp_settings.toml`, `temp_simproject.toml`
+  - `test_001.md`
+
+  For each candidate, run a grep across `tests/`, `scripts/`, `src/`, `docs/`:
+  ```powershell
+  rg "<filename>" tests/ scripts/ src/ docs/
+  ```
+  Expected: zero matches. If any match is found, PRESERVE that file (do NOT delete) and note in the commit message.
+
+  Also confirm each file is gitignored (or untracked):
+  ```powershell
+  git check-ignore -v tests/artifacts/test_parser.py
+  ```
+  Expected: prints a `.gitignore` rule for each. If any file is TRACKED, do NOT delete it without explicit user permission (HARD BAN on `git restore`/`git checkout --`).
+
+- [ ] **Step 2: Delete the verified files**
+
+  Use a single PowerShell command:
+  ```powershell
+  Remove-Item tests/artifacts/test_parser.py, tests/artifacts/test_patterns.py, tests/artifacts/test_regex.py, tests/artifacts/verify_layout.py, tests/artifacts/fake_test_output.txt, tests/artifacts/check_cwd.py, tests/artifacts/check_cwd_uv.py, tests/artifacts/exists.py, tests/artifacts/fix_stale_names.py, tests/artifacts/fix_conftest_layout.py, tests/artifacts/agents_skip_msg.txt, tests/artifacts/commit_layout_diag_msg.txt, tests/artifacts/configpath_msg.txt, tests/artifacts/context_presets_msg.txt, tests/artifacts/hooks_dictkey_msg.txt, tests/artifacts/reset_layout_msg.txt, tests/artifacts/st2a_prompt.txt, tests/artifacts/st2a_task.toml, tests/artifacts/st2g_msg.txt, tests/artifacts/st2g_msg2.txt, tests/artifacts/st2g_msg3.txt, tests/artifacts/stale_test_msg.txt, tests/artifacts/synthesis_crash_msg.txt, tests/artifacts/task1.toml, tests/artifacts/task1.txt, tests/artifacts/task2.toml, tests/artifacts/task2_1.txt, tests/artifacts/task3.toml, tests/artifacts/task3_1.txt, tests/artifacts/task4.toml, tests/artifacts/temp_config.toml, tests/artifacts/temp_data.txt, tests/artifacts/temp_liveaisettingssim.toml, tests/artifacts/temp_livecontextsim.toml, tests/artifacts/temp_liveexecutionsim.toml, tests/artifacts/temp_livetoolssim.toml, tests/artifacts/temp_notes.txt, tests/artifacts/temp_project.toml, tests/artifacts/temp_settings.toml, tests/artifacts/temp_simproject.toml, tests/artifacts/test_001.md, tests/artifacts/warmup_fix_msg.txt, tests/artifacts/workflow_skip_msg.txt, tests/artifacts/task_1_1.txt
+  ```
+
+  If `Remove-Item` fails because a file doesn't exist (already deleted or never existed), it's a no-op — that's fine.
+
+- [ ] **Step 3: Verify the directory still has the preserved files**
+
+  ```powershell
+  Get-ChildItem tests/artifacts
+  ```
+  Expected: only the preserved entries (`.gitignore`, `manualslop_layout_default.ini`, runtime state directories, referenced TOML files). No scratch files.
+
+- [ ] **Step 4: Commit the cleanup**
+
+  ```powershell
+  git add -A tests/artifacts
+  git status   # confirm no tracked files inside tests/artifacts were deleted
+  git commit -m "chore(artifacts): remove ~45 scratch files from tests/artifacts/"
+  ```
+
+  If the commit shows 0 changed files (everything was gitignored and deletion doesn't affect git), that's acceptable — the deletion is recorded in the working tree, not the git history.
+
+### Task 4.2: Conductor — User Manual Verification (Phase 4)
+
+- [ ] **Step 1: PAUSE and present the cleanup result**
+
+  > "Phase 4 complete. tests/artifacts/ now contains only the preserved files. Listing: <list>. Ready to commit Phase 4 checkpoint and finalize? (yes / changes needed)"
+
+- [ ] **Step 2: Create the Phase 4 checkpoint**
+
+  Capture the most recent commit hash (or note that the commit was empty). Attach a git note. Update `plan.md` Phase 4 status to `[x]` and append the hash (or "no SHA; gitignored delete" if no commit SHA).
+
+---
+
+## Phase 5: Track Finalization (Verification + Status Update)
+
+Focus: Re-run the full test suite (5 batches, 298 files) to confirm no regressions. Update `conductor/tracks.md`. Commit the plan update.
+
+### Task 5.1: Full suite regression run
+
+- [ ] **Step 1: Run the full test suite via the new orchestrator (or legacy, whichever is current default)**
+
+  If the refactor's Phase 3 is shipped, run:
+  ```powershell
+  uv run python scripts/run_tests_batched.py --tiers 1,2,3
+  ```
+  Otherwise, run the legacy:
+  ```powershell
+  uv run python scripts/run_tests_batched.py --batch-size 64
+  ```
+
+  Expected: all batches 1-4 pass; batch 5 (or tier 3 for the new orchestrator) may have failures. The per-file failure list now shows the actual files.
+
+- [ ] **Step 2: PAUSE and present the regression result**
+
+  > "Phase 5 verification: full suite run; per-file failure list verified. No regressions in batches 1-4. The track's verification criteria are all met. Ready to mark the track complete? (yes / changes needed)"
+
+### Task 5.2: Update `conductor/tracks.md`
+
+- [ ] **Step 1: Add a "Phase 9" chore-track entry for this track**
+
+  Format (mirroring existing entries):
+
+  ```markdown
+  - [x] **Track: Test Batching — Post-Refactor Polish** `[checkpoint: <sha>]`

+# Track Specification: Test Batching — Post-Refactor Polish
+
+**Status:** Active (spec authored 2026-06-08)
+**Initialized:** 2026-06-08
+**Owner:** Tier 2 Tech Lead
+**Priority:** Medium (developer ergonomics + observability; not a regression blocker)
+**Blocked by:** `test_batching_refactor_20260606` (must be SHIPPED before this track begins; the new orchestrator from the refactor is the target of the polish)
+**Blocks:** None
+
+---
+
+## 1. Problem Statement
+
+`test_batching_refactor_20260606` will replace the current `scripts/run_tests_batched.py` with a tier-based orchestrator that:
+- Uses `subprocess.run(cmd, capture_output=True, text=True)` to invoke each batch's pytest
+- On failure, prints the last 2000 chars of stdout (the new spec/plan, Phase 3 Task 3.1, line 1304: `print(proc.stdout[-2000:] if proc.returncode != 0 else ...)`)
+- Has no mechanism to surface the **actual failed file paths** to the user
+
+This is a regression in failure visibility vs. the current script (which lists every file in a failed batch — bad, but at least explicit). The new script will print a tail of pytest output that the user must manually scan for `FAILED ` lines.
+
+Three concrete improvements are deferred from the refactor to this track:
+
+1. **Per-file FAILED-line extraction** in the new orchestrator. When a tier batch fails, the script's summary should list the specific test files pytest reported as failed (parsed via str ops only, no regex per `AGENTS.md` standing ban). Same contract the current legacy script's `_extract_failed_files` (when fixed) will provide.
+2. **`live_gui` subprocess window foregrounding.** When the `live_gui` fixture spawns `sloppy.py`, the OS window must be raised to the foreground so the user watching the test can see the activity. Tier 3 (consolidated `live_gui`, 14+ `*_sim.py` files in one pytest invocation) amplifies this: without foregrounding, the user sees a hidden window for 30-60s while the tier runs.
+3. **`focus_test_panel(name)` test helper.** Live_gui tests should signal which panel they're exercising. The helper uses the existing `ApiHookClient.set_value` to toggle `show_windows[name] = True` and is called from individual `*_sim.py` test setup. The refactor's Tier 3 consolidation makes this signal-critical: the user needs to see WHICH panel is being driven, not just that something is happening.
+
+A fourth improvement is housekeeping: ~45 scratch files in `tests/artifacts/` from prior sessions (regex experimentation, layout baking debugging, sub-track task notes). These are gitignored but clutter the directory. Safe deletion is non-trivial (some files may be referenced by other tests or fixtures) so it's deferred to this track where it can be done carefully with verification.
+
+---
+
+## 2. Current State Audit (as of `2db14361 TEST LAYOUT`)
+
+### Already Implemented (DO NOT re-implement)
+
+| What | Where | Status |
+|---|---|---|
+| `App._diag_layout_state()` method | `src/gui_2.py:507-544` | Committed `818537b3`. Logs `[GUI] show_windows entries: N`, `[GUI] layout file: <path> (<bytes>)`, `[GUI] WARNING: layout has N stale window name(s)...` |
+| `manualslop_layout_default.ini` (user's preferred 2-column layout) | `tests/artifacts/manualslop_layout_default.ini` (2,699 bytes) | Whitelisted in `.gitignore` line 17. Confirmed loaded by `_diag_layout_state` log. |
+| `tests/conftest.py:418-421` copies the layout artifact into the test workspace | `tests/conftest.py:418-421` | Replaces the prior "do NOT copy" block from `7a4f71e7` |
+| `_default_windows` updated for 12-window visible-by-default set | `src/app_controller.py:1832-1855` | MMA Dashboard=False, Log Management=True, Diagnostics=True |
+| `_STALE_WINDOW_NAMES` set | `src/gui_2.py:530-533` | 10 names (Theme removed; was incorrectly flagged as stale) |
+| Skip markers from `e09e6823` resolved | `8d58d7fc` (warmup races), `a36aad50` (gui_events_v2), `91b34ae8` (live_gui_filedialog), `ff523f7e` (project_switch_persona) | 3 of 5 fixed in subsequent commits; 2 in `8d58d7fc` |
+| `RUN_MMA_INTEGRATION` env-var gate on `test_mma_step_mode_sim.py` | `tests/test_mma_step_mode_sim.py:24-27` | Appropriate opt-in integration gate, not a broken test |
+| `scripts/cleanup_orphaned_processes.py` | Committed `5e1867bb` | Manages stale subprocesses; preserves MCP servers |
+| `_extract_failed_files` (in legacy `run_tests_batched.py`, if Phase 0 ships) | `scripts/run_tests_batched.py:30-50` (post-Phase-0) | Str-ops-only FAILED-line parser; 11 unit tests in `tests/test_run_tests_batched.py` |
+
+### Gaps to Fill (This Track's Scope)
+
+| Gap | Severity | Where the fix lands |
+|---|---|---|
+| New orchestrator's `subprocess.run(capture_output=True)` only prints stdout tail on failure — no per-file failure list | **High** | New `scripts/run_tests_batched.py` (post-refactor) — the `_run_batch` helper around line 1296-1308 of the refactor's plan |
+| `live_gui` fixture doesn't bring sloppy.py's window to front | **Medium** | `tests/conftest.py:live_gui` fixture |
+| `live_gui` tests have no per-test focus signal | **Medium** | `tests/conftest.py` (new helper) + per-test callsites in 14+ `*_sim.py` files |
+| `tests/artifacts/` has ~45 scratch files from prior sessions | **Low** | `tests/artifacts/*.py`, `tests/artifacts/*.txt`, `tests/artifacts/*.toml` (verify references first) |
+| The `_extract_failed_files` from Phase 0 of the refactor (if shipped) lives in the LEGACY script that gets renamed to `.legacy` in Phase 3, then deleted in Phase 4 | **Critical** | The function needs to be lifted to a shared location (e.g., `scripts/test_failure_parser.py`) so both legacy and new orchestrator use the same code |
+
+---
+
+## 3. Goals
+
+1. **Per-file FAILED-line extraction in the new orchestrator.** When any tier batch fails, the summary lists the specific test files pytest reported as failed (via str ops only, no regex). On timeout, fall back to listing the whole batch with `(timeout)` annotation.
+2. **Lift `_extract_failed_files` to a shared library.** The function lives in `scripts/test_failure_parser.py` (or similar); both the legacy script and the new orchestrator import it. No code duplication.
+3. **`live_gui` subprocess window foregrounding.** When the fixture spawns `sloppy.py`, find the child window by PID and call `ShowWindow` + `SetForegroundWindow`. No-op on non-Windows or when pywin32 is unavailable. Wrapped in `try/except`; never raises.
+4. **`focus_test_panel(name)` helper.** New module-level function in `tests/conftest.py` that uses the existing `ApiHookClient.set_value` to toggle `show_windows[name] = True`. Returns True/False (False if hook server unreachable).
+5. **Wire `focus_test_panel` into at least 3 starter `*_sim.py` tests** so the pattern is established for the refactor's consolidated Tier 3.
+6. **Clean up `tests/artifacts/` scratch files** (with verification of non-reference first).
+
+---
+
+## 4. Functional Requirements
+
+### 4.1 Shared `_extract_failed_files` library
+
+**FR-1.** Create `scripts/test_failure_parser.py` containing the `_extract_failed_files(output: str) -> list[str]` function. Str-ops-only (no `re` import per `AGENTS.md`).
+
+**FR-2.** The function SHALL:
+- Accept the full captured stdout+stderr from a pytest invocation
+- Parse lines beginning with the literal 7-character prefix `FAILED ` (note trailing space)
+- Extract the test ID, ending at the first ` - ` (space-dash-space) separator
+- If the test ID contains `::`, take the file path portion (before the first `::`)
+- Normalize backslashes to forward slashes (Windows path safety)
+- Strip a leading `tests/` prefix to return the bare filename
+- Deduplicate (preserve first-occurrence order)
+
+**FR-3.** Update the legacy `scripts/run_tests_batched.py` to import `_extract_failed_files` from the new shared module (if it was implemented locally in the refactor's Phase 0; otherwise add it there for the first time).
+
+**FR-4.** Update the new orchestrator (post-refactor) to call `_extract_failed_files` on the captured stdout/stderr in `_run_batch` when `returncode != 0`. Use the returned list to populate the SUMMARY table's per-file failure list.
+
+**FR-5.** Add 11+ unit tests in `tests/test_test_failure_parser.py` covering the contract from FR-2 (same set as the original 11 tests for the legacy script, ported to the new module).
+
+### 4.2 New Orchestrator Per-File Failure List
+
+**FR-6.** In the new `scripts/run_tests_batched.py:_run_batch` (post-refactor), on non-zero exit:
+- Call `_extract_failed_files(proc.stdout + proc.stderr)` (combined)
+- If the returned list is non-empty, add those files to the per-tier failure list
+- If the returned list is empty (rare; collection errors, plugin crashes), add the whole batch's files with a `(no FAILED lines; treating as batch failure)` annotation
+
+**FR-7.** On `subprocess.TimeoutExpired` (the batch exceeded `--timeout`): fall back to `failed_files.extend(batch)` with `(timeout)` annotation (per-file accuracy impossible on timeout — same as legacy).
+
+**FR-8.** The SUMMARY table (new orchestrator's `_print_summary`) SHALL include a per-file failure listing when any tier failed:
+```
+[TIER 3] live_gui              FAIL   14/14  47.2s
+   - tests/test_foo.py
+   - tests/test_bar.py
+```
+
+**FR-9.** The orchestrator's worst-case exit code SHALL be 1 if any tier has a per-file failure list, 0 if all tiers passed or were skipped.
+
+### 4.3 Live_Gui Window Foregrounding (`tests/conftest.py`)
+
+**FR-10.** Add module-level function `_foreground_subprocess_window(pid: int, attempts: int = 3, delay_s: float = 0.5) -> None` to `tests/conftest.py`.
+
+**FR-11.** The function SHALL:
+- No-op immediately on `os.name != "nt"`
+- Try-except `import win32gui, win32con`; no-op on `ImportError`
+- Loop `attempts` times: `win32gui.EnumWindows` to find a top-level visible window whose owning PID matches `pid`; on match, call `win32gui.ShowWindow(hwnd, win32con.SW_SHOWNORMAL)` then `win32gui.SetForegroundWindow(hwnd)`
+- Sleep `delay_s` between attempts (the subprocess may take 1-2s to create its window)
+- Wrap the whole body in `try/except Exception`; log a `[Fixture] WARNING: ...` line and return on any error; NEVER raise into the test fixture
+
+**FR-12.** Wire the helper into the `live_gui` fixture: insert one line `_foreground_subprocess_window(proc.pid)` immediately after the `subprocess.Popen(...)` call returns.
+
+**FR-13.** Add 3 unit tests in `tests/test_live_gui_foregrounding.py` asserting: helper exists and is callable; helper is no-op on invalid PIDs; helper is no-op when `win32gui`/`win32con` import fails (monkeypatched).
+
+### 4.4 `focus_test_panel` Helper
+
+**FR-14.** Add module-level function `focus_test_panel(panel_name: str, host: str = "127.0.0.1", port: int = 8999) -> bool` to `tests/conftest.py`.
+
+**FR-15.** The function SHALL:
+- Try-except `from src.api_hook_client import ApiHookClient`; return False on `ImportError`
+- Instantiate `ApiHookClient(host=host, port=port)`
+- Call `client.wait_for_server(timeout=0.5)`; return False if the server is not reachable
+- Call `client.set_value(f'show_windows["{panel_name}"]', True)`
+- Wrap the whole body in `try/except Exception`; log a `[focus_test_panel] ...` line and return False on any error
+- Return True on success
+
+**FR-16.** The function is OPTIONAL for tests: tests that don't call it get existing behavior. Tests that call it signal intent. The function's return value is informational (caller may choose to skip on False).
+
+**FR-17.** Wire `focus_test_panel` into at least 3 starter `*_sim.py` files (one-line addition in test setup, immediately after `client.wait_for_server(...)`):
+- `tests/test_command_palette_sim.py`: `focus_test_panel("Command Palette")`
+- `tests/test_workflow_sim.py`: `focus_test_panel("Discussion Hub")`
+- `tests/test_undo_redo_sim.py`: `focus_test_panel("Discussion Hub")`
+
+### 4.5 `tests/artifacts/` Scratch Cleanup
+
+**FR-18.** Verify each candidate scratch file is NOT referenced by any test or fixture (use `rg "<filename_without_ext>" tests/ scripts/ src/ docs/` and confirm zero matches).
+
+**FR-19.** For files with zero references, delete them. The candidate list (from prior session's report + my own audit of `tests/artifacts/`):
+- `test_parser.py`, `test_patterns.py`, `test_regex.py` (regex experimentation)
+- `verify_layout.py`, `check_cwd.py`, `check_cwd_uv.py`, `exists.py`, `fix_stale_names.py`, `fix_conftest_layout.py` (layout + cwd debugging)
+- `fake_test_output.txt` (sample data for parser testing)
+- `agents_skip_msg.txt`, `commit_layout_diag_msg.txt`, `configpath_msg.txt`, `context_presets_msg.txt`, `hooks_dictkey_msg.txt`, `reset_layout_msg.txt`, `st2a_prompt.txt`, `st2a_task.toml`, `st2g_msg.txt` (3 copies), `stale_test_msg.txt`, `synthesis_crash_msg.txt`, `warmup_fix_msg.txt`, `workflow_skip_msg.txt` (agent scratch messages)
+- `task1.toml`–`task4.toml`, `task1.txt`–`task_3_1.txt` (task notes)
+- `temp_config.toml`, `temp_data.txt`, `temp_live*.toml`, `temp_notes.txt`, `temp_project.toml`, `temp_settings.toml`, `temp_simproject.toml` (temp scratch)
+- `test_001.md` (25KB scratch markdown)
+
+**FR-20.** The following SHALL be PRESERVED:
+- `tests/artifacts/manualslop_layout_default.ini` (whitelisted in `.gitignore`)
+- `tests/artifacts/manual_slop.toml`, `repro_project.toml`, `test_snapshot_project.toml` (referenced by fixtures)
+- `tests/artifacts/live_gui_workspace/`, `repro_workspace/`, `temp_workspace/`, `gui_ux_sim/`, `test_isolated_project/`, `test_link_workspace/`, `conductor/`, `.slop_cache/` (runtime state)
+- `tests/artifacts/.gitignore` (in-place gitignore for the subdirectory)
+
+---
+
+## 5. Non-Functional Requirements
+
+**NFR-1.** 1-space indentation throughout all Python changes (per `conductor/product-guidelines.md`).
+**NFR-2.** CRLF line endings on Windows for all changed `.py` files.
+**NFR-3.** No inline comments in production code (per `AGENTS.md`).
+**NFR-4.** No `re` (regex) module imports in the failure parser. Verify with `grep -n "import re\|from re" scripts/test_failure_parser.py` returning empty after the change.
+**NFR-5.** No new external dependencies. No `pyproject.toml` change.
+**NFR-6.** Type hints required for all new functions and the modified `run_batch` signature in the new orchestrator.
+**NFR-7.** The window-foregrounding helper SHALL NOT call `SetForegroundWindow` more than 3 times per session (Windows throttles repeated foreground-stealing attempts).
+**NFR-8.** All commits are atomic per-task (per `conductor/workflow.md` "Definition of Done").
+
+---
+
+## 6. Architecture Reference
+
+- **`docs/guide_architecture.md` "Thread domains"** — the live_gui fixture runs in the pytest process (foreground); sloppy.py runs in a subprocess. The fixture → subprocess communication is over the Hook API (`127.0.0.1:8999`). Window-foregrounding uses a separate channel (Windows OS API; `win32gui`).
+- **`docs/guide_testing.md` "live_gui fixture"** — the session-scoped fixture's lifecycle.
+- **`docs/guide_api_hooks.md` "ApiHookClient.set_value"** — the existing mechanism for toggling `show_windows[name]`. The new `focus_test_panel` helper uses this.
+- **`docs/guide_simulations.md` "Puppeteer pattern"** — existing pattern for live_gui tests; the new `focus_test_panel` is a small variant of the same shape.
+- **`conductor/tracks/test_batching_refactor_20260606/spec.md` §3.3 "Six Tiers"** — Tier 3 (live_gui) is the upstream system this track polishes. The new orchestrator's `_run_batch` is the integration point for the per-file failure list.
+- **`conductor/tracks/startup_speedup_20260606/state.toml` §`conftest_warmup_wait`** — the fixture's existing warmup-blocking wait runs at conftest load time, before the live_gui fixture executes. The new window-foregrounding code runs AFTER the subprocess spawns (not at load time) and is therefore orthogonal.
+- **`AGENTS.md` "Critical Anti-Patterns"** — re-affirms the standing ban on `re` (regex) module imports in the codebase. The user has threatened a 10-page report if they see regex.

+
+## 7. Coordination with `test_batching_refactor_20260606`
+
+| Refactor phase | What this track does after it ships |
+|---|---|
+| **Phase 1** (Library + dry-run) | Nothing; legacy script unchanged. |
+| **Phase 2** (Shadow run) | Nothing; shadow run still uses legacy + new in parallel. |
+| **Phase 3** (Switch default, rename legacy to `.legacy`) | The legacy's `_extract_failed_files` (if implemented in refactor's Phase 0) is moved to `scripts/test_failure_parser.py` so the new orchestrator can use it without forking. The new orchestrator's `_run_batch` is updated to call the shared parser. |
+| **Phase 4** (Cleanup, delete legacy) | The legacy is deleted; `scripts/test_failure_parser.py` is the sole home of the FAILED-line parser. |
+
+### 7.1 Open question for the refactor (recorded, not fixed here)
+
+The refactor's `scripts/test_categorizer.py::auto_classify()` rule #2 uses **regex** in the spec (`AGENTS.md` ban conflict):
+> `\(live_gui\)\s*[:,)]` regex match in source
+
+The user has confirmed they will instruct the implementing agent to convert this to AST-based detection (`ast.parse` → walk `FunctionDef` for `live_gui` in args). This is **the refactor's responsibility**, not this post-refactor track's.
+
+---
+
+## 8. Out of Scope
+
+- **The test batching refactor itself** — owned by `test_batching_refactor_20260606`.
+- **Auto-classification regex → AST conversion** — the user will instruct the agent directly; not part of this track.
+- **Tracked `manualslop_layout.ini` at repo root** — requires explicit user permission per the user's HARD BAN on `git restore`/`git checkout --`. The conftest no longer copies it to the test workspace (regression fixed in `7a4f71e7`).
+- **User's TOML files** (`config.toml`, `project.toml`, `project_history.toml`) — explicitly excluded per the user's standing constraint.
+- **New audit scripts** — none introduced. The existing audit set is sufficient.
+- **The skip markers from `e09e6823`** — 3 fixed in subsequent commits, 2 in `8d58d7fc`. No skip markers remain that this track needs to address.
+- **The `__getattr__` cheat audit work** — separate track referenced in `conductor/reports/AUDIT_ARCHITECTURAL_CHEATS_20260607.md`.
+- **Performance baseline** — the refactor's `--durations` feature records runtimes. Generating that file is a Phase 1 task of the refactor, not this track.
+
+---
+
+## 9. Verification Criteria
+
+This track is "done" when **all** of the following are true:
+
+- [ ] `scripts/test_failure_parser.py` exists and exports `_extract_failed_files` (no `re` import; verify with `grep -n "import re\|from re" scripts/test_failure_parser.py` returning empty).
+- [ ] 11+ unit tests in `tests/test_test_failure_parser.py` all pass.
+- [ ] The legacy `scripts/run_tests_batched.py` (if not yet deleted by the refactor) imports `_extract_failed_files` from the new module.
+- [ ] The new `scripts/run_tests_batched.py` (post-refactor) `_run_batch` calls `_extract_failed_files` on captured output and includes the per-file failure list in the SUMMARY table.
+- [ ] `tests/conftest.py:_foreground_subprocess_window` exists; 3 unit tests pass; the live_gui fixture calls it after `subprocess.Popen(...)`.
+- [ ] `tests/conftest.py:focus_test_panel` exists; 3+ `*_sim.py` tests call it in setup.
+- [ ] The scratch files from FR-19 are deleted; the directory only contains the preserved files/directories from FR-20.
+- [ ] The existing test suite still passes for batches 1-4 (no regressions).
+- [ ] Batch 5's timeout (test_z_negative_flows) is reported as exactly 1 failed file, not all 42.
+- [ ] All commits are atomic per-task with descriptive messages.
+- [ ] No commits include the user's TOML files.
+- [ ] No commits include `manualslop_layout.ini` at the repo root.

+# Unused Scripts Cleanup Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Remove 30 confirmed-unused scripts from `scripts/` via 5 atomic per-category commits, shrinking the directory from 56 → 26 files (54% reduction).
+
+**Architecture:** Hard deletes via `git rm`. Each deletion category is one phase → one commit. The git log is the restore path; per-category commits give surgical rollback granularity. The "test" for each phase is the existing test suite (4-at-a-time batches per `conductor/workflow.md` Phase Completion protocol). No new code, no new tests, no new CI gate.
+
+**Tech Stack:** PowerShell (Windows), git, pytest, `uv run` (per project convention).
+
+---
+
+## Phase 0: Pre-deletion baseline
+
+**Files:** `conductor/tracks/unused_scripts_cleanup_20260607/state.toml` (create).
+
+- [ ] **Step 0.0: Create `state.toml`**
+
+The `state.toml` is the implementer's "where am I in this track" source of truth. Write `conductor/tracks/unused_scripts_cleanup_20260607/state.toml` with the initial structure (per `conductor/workflow.md` "State.toml Template"):
+
+```toml
+# Track state for unused_scripts_cleanup_20260607
+# Updated by Tier 2 Tech Lead as tasks complete
+
+[meta]

+
+[verification]
+scripts_count_baseline = 56
+scripts_count_target = 26
+tests_passing_at_baseline = true
+```
+
+- [ ] **Step 0.0a: Update `state.toml` after each phase**
+
+After each of Phase 1-5 lands, update `state.toml`:
+- Set the phase's `status = "completed"` and `checkpointsha = "<the commit SHA>"`.
+- Bump `[meta].current_phase` to the next phase number.
+- Update `[meta].last_updated` to the current date.
+- Commit the `state.toml` change with message: `conductor(plan): mark phase N complete [short-sha]`.
+
+(Step 6 of `conductor/workflow.md` Task Workflow.)
+
+- [ ] **Step 0.1: Capture baseline test state**
+
+Run: `git log -1 --format="%H"` (record: `___________`)
+Run: `(Get-ChildItem -LiteralPath scripts -File).Count` (record: `___________`, expect 56)
+
+- [ ] **Step 0.2: Re-verify the 30 deletions have no external references**
+
+Run the following to confirm the audit is still valid (the project has not gained new references to any of the 30 files since the spec was written):
+
+```powershell
+$files = @(
+  "audit_indentation.py","check_hints_v2.py","correct_indentation.py","extract_symbols.py",
+  "fix_gaps.py","fix_indent.py","fix_indent_ast.py","fix_indent_v3.py","standardize_indent.py",
+  "type_hint_scanner.py",
+  "apply_startup_timeline.py","apply_type_hints.py","gut_oop_final.py","restore_regions_final.py",
+  "transform_render_methods.py","transform_render_methods_safe.py",
+  "audit_entropy.py","comprehensive_entropy_audit.py","focused_entropy_audit.py","code_stats.py",
+  "migrate_cruft.ps1","profile_baseline.py","repro_history.py","sdm_injector.py","sdm_mapper.py",
+  "update_paths.py",
+  "scan_all_hints.py","tool_call.bat","tool_call.cmd","tool_discovery.py"
+)
+$bad = @()
+foreach ($f in $files) {
+  $hits = git grep -lF "scripts/$f" -- ':!scripts/'"$f" 2>$null
+  if ($hits) { $bad += "$f -> $hits" }
+}
+if ($bad) { $bad | ForEach-Object { Write-Host $_ }; exit 1 } else { Write-Host "OK: 0 external references" }
+```
+
+Expected output: `OK: 0 external references`. Exit code 0.
+
+If any file shows hits, STOP and report to the Tier 2 Tech Lead. The spec is stale.
+
+- [ ] **Step 0.3: Confirm `slice_tools.py` and `validate_types.ps1` still exist (they are KEEPS)**
+
+```powershell
+Test-Path scripts/slice_tools.py
+Test-Path scripts/validate_types.ps1
+```
+
+Expected: both `True`.
+
+- [ ] **Step 0.4: Stage nothing, do not commit. Move to Phase 1.**
+
+---
+
+## Phase 1: Remove one-shot indent fixers (10 files, 1 commit)
+
+**Files:** `git rm` 10 files in `scripts/`.
+
+- [ ] **Step 1.1: `git rm` the 10 files**
+
+```bash
+git rm scripts/audit_indentation.py scripts/check_hints_v2.py scripts/correct_indentation.py scripts/extract_symbols.py scripts/fix_gaps.py scripts/fix_indent.py scripts/fix_indent_ast.py scripts/fix_indent_v3.py scripts/standardize_indent.py scripts/type_hint_scanner.py
+```
+
+- [ ] **Step 1.2: Run a quick test sanity check (one batch, ~30s)**
+
+Run: `uv run pytest tests/test_main_thread_purity.py tests/test_mcp_client_whitelist_enforcement.py -q 2>&1 | Select-Object -Last 20`
+
+Expected: tests pass (these tests import a few scripts modules; if they fail to import, something else was referencing the removed files — STOP and report).
+
+- [ ] **Step 1.3: Commit**
+
+```bash
+git commit -m "chore(scripts): remove one-shot indentation fixers
+
+The 1-space indentation convention is now enforced project-wide
+(per fix_indentation_1space_20260516). These 10 scripts are
+overlapping one-shot fixers and auditors from that era; their
+purpose has been served.
+
+Removed (10 files, ~30 KB):
+- audit_indentation.py (4.6 KB) - indentation auditor
+- check_hints_v2.py (1.0 KB) - crude regex hint checker
+- correct_indentation.py (6.4 KB) - one-shot corrector

+# Track: Unused Scripts Cleanup
+
+**Status:** Spec approved 2026-06-07
+**Initialized:** 2026-06-07
+**Owner:** Tier 2 Tech Lead
+**Priority:** Low (chore; cleanup, not feature)
+
+---
+
+## Overview
+
+Remove 30 confirmed-unused scripts from `scripts/` so the directory contains only active MMA/MCP/CI/test infrastructure, kept-by-utility tools, or infrastructure referenced by a planned future track. Net effect: `scripts/` shrinks from 56 → 26 files (54% reduction).
+
+All deletions are **hard deletes** via 5 atomic per-category commits. The git log is the restore path; per-category commits give surgical rollback granularity (each commit is one logical category that stands or falls together). No new CI gate is added in this track; a follow-up `unused_scripts_audit_20260607` is recorded in §Follow-up.
+
+## Current State Audit (as of `a88c748d`)
+
+`scripts/` currently has 56 files in five functional buckets. The audit below is data-grounded: a project-wide grep confirms the "keep" reasons (live references in active code, docs, CI, or planned tracks) and the absence of references for the 30 "remove" files.
+
+### Already Implemented (KEEP — DO NOT touch, 26 files)
+
+1. **CI audit gates (3 files, 17.7 KB total).**
+   - `audit_main_thread_imports.py` — CI gate from `startup_speedup_20260606` (T1.4, commit `6f9a3af2`); referenced by `conductor/workflow.md:584`, `tests/test_main_thread_purity.py:12`, and 4 active planned tracks.
+   - `audit_weak_types.py` — CI gate from `data_structure_strengthening_20260606` (commit `84fd9ac9`); will gain `--strict` mode in that track.
+   - `check_test_toml_paths.py` — CI gate from `test_consolidation_20260606` (commit `1660114b`).
+
+2. **MMA infrastructure (5 files, 34.7 KB total).**
+   - `mma_exec.py` — referenced 100+ times in `workflow.md`, `tracks.md`, all 5 active planned tracks, `AGENTS.md`. The MMA bridge.
+   - `mma.ps1` — PowerShell wrapper for `mma_exec.py`.
+   - `claude_mma_exec.py` (10 KB) — alternative MMA bridge; documented in `docs/Readme.md:18` and `docs/guide_meta_boundary.md` as a Meta-Tooling inter-domain bridge.
+   - `claude_tool_bridge.py` (3.8 KB), `cli_tool_bridge.py` (6.5 KB) — inter-domain bridges per `docs/guide_meta_boundary.md`. Active in `tests/test_cli_tool_bridge.py` and `tests/test_cli_tool_bridge_mapping.py`.
+
+3. **MCP infrastructure (3 files, 13.4 KB total).**
+   - `mcp_server.py` (3.2 KB) — referenced in `opencode.json:27` as an MCP server entry.
+   - `mock_mcp_server.py` (1.6 KB) — referenced by `tests/test_cli_tool_bridge_mapping.py` and other bridge tests.
+   - `py_struct_tools.py` (8.6 KB) — shared AST/regex logic for `src/mcp_client.py` dispatch; created in `conductor/archive/python_structural_mcp_tools_20260513/plan.md:4` (commit `d044ccb2`).
+
+4. **Test runner (1 file).** `run_tests_batched.py` (1.3 KB) — the test runner being upgraded by `test_batching_refactor_20260606`.
+
+5. **ImGui linter (1 file).** `check_imgui_scopes.py` (3.5 KB) — mandatory per `conductor/product-guidelines.md:26`; referenced by 4 archived plans and the workflow.
+
+6. **Audit / scaffolding (4 files).**
+   - `audit_gui2_imports.py` (3.7 KB) — startup_speedup T1.2 (commit `6f9a3af2`).
+   - `benchmark_imports.py` (7.3 KB) — startup_speedup T1.1 (commit `2adf3274`).
+   - `run_subagent.ps1` (3.2 KB) — active MMA sub-agent invocation.
+   - `__init__.py` (0 bytes) — empty package marker.
+
+7. **Tool-call bridge (4 files, ≈ 2.8 MB total — dominated by the compiled binary).**
+   - `tool_call.cpp` (1.5 KB, source), `tool_call.exe` (2.8 MB, compiled binary), `tool_call.py` (1.6 KB, Python bridge), `tool_call.ps1` (123 B, PowerShell wrapper) — used by the inter-domain tool-call system referenced in `docs/guide_meta_boundary.md`. The `tool_call.bat` and `tool_call.cmd` aliases are being removed in this track (see §"Gaps to Fill", commit 5).
+
+8. **Docker (3 files).** `docker_build.sh` (164 B), `docker_push.ps1` (1.5 KB), `docker_run.sh` (141 B) — referenced by `docs/superpowers/plans/2026-06-02-docker-web-frontend.md` (planned track).
+
+9. **Borderline utility (2 files, KEEP per review).**
+   - `slice_tools.py` (2.4 KB) — general-purpose CLI primitive: `get_slice` / `set_slice` / `get_def`. Standalone alternative to `mcp_client`'s file_slice tools; could be used in future AST-driven refactor scripts.
+   - `validate_types.ps1` (671 B) — plausible ad-hoc `ruff` + `mypy` runner on 5 core files. No current consumer, but small and plausibly useful.
+
+### Gaps to Fill (this track's scope — 30 file deletions)
+
+These 30 files are confirmed one-off tools from past tracks; their purpose has been served and no current code, doc, or CI references them. Grouped by deletion commit:
+
+| Commit | File | Size | Origin / why it's a one-off |
+|--------|------|------|------------------------------|
+| 1 | `audit_indentation.py` | 4.6 KB | 1-space indentation is now enforced project-wide (track `fix_indentation_1space_20260516`). Only referenced in that archived plan. |
+| 1 | `check_hints_v2.py` | 1.0 KB | Crude regex-based hint checker on 4 hardcoded files. Superseded by `scan_all_hints.py` (now also being removed). |

+
+**Total deletions:** 30 files, ~115 KB. **Net scripts/ count after track:** 26 files.
+
+## Goals
+
+- Remove the 30 confirmed-unused scripts from `scripts/` so the directory is a curated home for active infrastructure.
+- Maintain project invariants: all 5 per-category commits are atomic; the test suite passes after each commit; the kept `slice_tools.py` and `validate_types.ps1` remain importable and functional.
+- Document the per-file rationale in the spec so a future re-evaluation is fast.
+
+## Functional Requirements
+
+- **F1.** Each of the 30 deletions is committed in the correct category group (1 of 5 atomic commits per §Commit Structure).
+- **F2.** Each commit message includes a brief summary of why these scripts are being removed (per `conductor/workflow.md` step 9 commit message format).
+- **F3.** A `git notes add -m "..."` is attached to each commit per `conductor/workflow.md` steps 10.1-10.3, summarizing the deletion rationale and listing the removed files.
+- **F4.** The `state.toml` for this track (created by the Tier 2 implementer) reflects all 5 commit SHAs and advances `current_phase` to "complete" after the final commit.
+- **F5.** `tracks.md` is updated to add the track entry in the appropriate section (chronological, under whatever phase corresponds to 2026-06-07).
+
+## Non-Functional Requirements
+
+- **NFR1 (Per-category atomicity).** 5 atomic commits, not 30 individual file commits. Each commit's diff is reviewable in isolation; rollback is per-category.
+- **NFR2 (No CI gate in this track).** The follow-up `unused_scripts_audit_20260607` will add `scripts/audit_unused_scripts.py --strict` if desired. Not in scope here.
+- **NFR3 (No documentation changes).** The audit confirms no doc references any of the 30 files by name; no doc churn is required.
+- **NFR4 (No code style application).** N/A — this is deletion only; no new code.
+- **NFR5 (No new tests required).** The existing test suite is the regression net; if no test breaks after the 30 deletions, the track is verifiably safe.
+
+## Commit Structure
+
+5 atomic commits, in order:
+
+```
+1. chore(scripts): remove one-shot indentation fixers
+   (10 files)
+2. chore(scripts): remove one-shot transform scripts
+   (6 files)
+3. chore(scripts): remove superseded entropy and code-stat audits
+   (4 files)
+4. chore(scripts): remove one-shot migrators and repros
+   (6 files)
+5. chore(scripts): remove tool_call aliases and legacy tool discovery
+   (4 files; scan_all_hints.py + tool_call.bat + tool_call.cmd + tool_discovery.py)
+```
+
+Each commit message also gets a `git notes add -m "..."` summary per `conductor/workflow.md` (per-task commit + git note + state.toml pattern).
+
+## Architecture Reference
+
+- `docs/guide_meta_boundary.md` — explains the inter-domain bridge pattern (why `claude_mma_exec.py`, `cli_tool_bridge.py`, `claude_tool_bridge.py`, `mcp_server.py` are kept).
+- `docs/guide_architecture.md` — explains the MMA/MCP infrastructure layer that the kept scripts support.
+- `conductor/workflow.md` "Task Workflow" — per-task commit + git note + state.toml pattern (applied to this track).
+- `conductor/workflow.md` "Audit Script Policy" — the audit-script + styleguide pair; the future `unused_scripts_audit_20260607` follow-up will follow this pattern.
+- `conductor/archive/cull_unused_symbols_20260507/` — prior similar cleanup (src/ symbols, 27 removed) for format reference.
+
+## Out of Scope
+
+- **Active infrastructure (26 KEEPS listed in §"Already Implemented").** Do not touch.
+- **Docker scripts (3 files).** Kept; referenced by the planned Docker track.
+- **`__init__.py`.** Kept (package marker).
+- **`slice_tools.py` and `validate_types.ps1`.** Kept (borderline utility, per the per-file review).
+- **`conductor/archive/`, `tests/artifacts/`, `.claude/commands/`, `.gemini/`, `opencode.json`, `docs/`.** Different domains; not in scope.
+- **Follow-up `unused_scripts_audit_20260607`.** Recorded in §Follow-up, NOT done in this track.
+- **Re-evaluating the kept-among-borderline files.** `slice_tools.py` and `validate_types.ps1` are kept as-is.
+
+## Follow-up
+
+- **`unused_scripts_audit_20260607`** (planned, NOT in this track): adds `scripts/audit_unused_scripts.py` with `--strict` mode and a baseline file. Mirrors the `scripts/audit_weak_types.py` / `data_structure_strengthening_20260606` pattern. Catches "new unused script was added" before it lands.
+
+  **Rationale for deferral:** (1) the project has 3 audit scripts already; adding a 4th is a maintenance commitment; (2) the cleanup is small enough that one-time adjudication is more appropriate than permanent enforcement right now; (3) the audit script itself would be in `scripts/` — adding a self-policing layer to a directory that just shrank is overkill for one track.
+
+  **Trigger to start this follow-up:** when `scripts/` grows back to 35+ files (the post-cleanup count is 26; +9 = 35 is a soft signal that one-off tools are accumulating again).
+
+## Coordination with Pending Tracks
+
+This track has **no blockers** and **no conflicts**. It can ship independently of, and in parallel with, the 5 active planned tracks:
+
+| Pending track | Effect on `scripts/` | Conflict? |
+|---------------|----------------------|-----------|
+| `test_batching_refactor_20260606` | +3 (`test_categorizer`, `test_batcher`, `pytest_collection_order`) | None (additive) |
+| `qwen_llama_grok_integration_20260606` | 0 (all in `src/`) | None |
+| `data_oriented_error_handling_20260606` | 0 (all in `src/`) | None |
+| `data_structure_strengthening_20260606` | +1 (`generate_type_registry.py`) | None |
+| `mcp_architecture_refactor_20260606` | 0 (all in `src/`) | None |
+
+After all 5 planned tracks + this track ship, `scripts/` will have 30 files (26 from this cleanup + 3 from test batching + 1 from data structure strengthening). All under active maintenance.
+
+## Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| A removed script was being invoked by hand by the user (not in any code path the grep caught). | Low | Low (one-time re-invocation fails) | `git log -- scripts/<file>` is one click; per-category commits make rollback surgical. |
+| The user re-evaluates and decides one of the 30 has utility. | Low | Low (work to restore) | The per-file rationale in §"Gaps to Fill" documents the why; per-category commits can be reverted in one step. |
+| An LLM sub-agent reaches for one of the removed scripts during an MMA task. | Very low | Low (the LLM's tool list comes from `mcp_client`, not `scripts/`) | None needed; the MMA Tier 3 prompt seeds the sub-agent with the project layout, which no longer lists the removed scripts after the commits land. |
+| A test file imports one of the 30 (e.g., `from scripts.scan_all_hints import ...`) that the audit missed. | Very low (audit was comprehensive) | Medium (test failure) | Full test suite in 4-at-a-time batches per `workflow.md` Phase Completion protocol; rollback the affected commit if it fails. |

 ## Known Pitfalls (2026-06-05)
 
+### HARD BAN: `git checkout -- <file>`, `git restore`, `git reset` (Added 2026-06-10)
+
+**Per AGENTS.md (Critical Anti-Patterns):** These three commands are FORBIDDEN without explicit user permission in the same message. They destroyed user in-progress `src/*` edits twice in one session (2026-06-07). If you think you need one, ASK FIRST.
+
+The intent of "look at what the file looked like at commit X" is non-destructive inspection. The CORRECT way:
+
+```bash
+# WRONG: overwrites the working tree
+git checkout HEAD~1 -- src/foo.py
+
+# RIGHT: prints to stdout, leaves working tree alone
+git show HEAD~1:src/foo.py
+```
+
+`git checkout -- <file>` and `git restore` are particularly dangerous because:
+- They overwrite uncommitted changes silently
+- They overwrite previously-committed state in the working tree if the user has already committed and then re-edited
+- The user doesn't see the loss until they notice missing changes
+
+If you genuinely need to revert (e.g., the working tree is broken from a previous agent), use `git stash` first to capture the in-progress state, ASK THE USER, then proceed.
+
+This was the actual cause of the 2026-06-10 `mma_tier_usage_reset_fix` regression: an agent used `git checkout --` to "peek at baseline", which overwrote the just-committed FR1+FR2 fixes. Recovery was via re-applying the fixes with `edit_file` (option B chosen by the user). Don't repeat this.

 ### Defer-Not-Catch Pattern for Native Crashes
 
 `imgui-bundle` (and similar native extension libraries) expose C-level functions that can crash the Python process with a Windows access violation (`0xc0000005`) or a SIGSEGV on Linux. **These crashes are not catchable from Python** — `try/except Exception` does not intercept native access violations, only Python exceptions.
@@ -426,6 +449,33 @@ In particular, watch for:
 
 `live_gui` is a session-scoped fixture. All tests in a session share the same `sloppy.py` subprocess. A test that "passes when run after test X but fails in isolation" is a **fragile test, not a fragile fixture**. The fixture is session-scoped by design; the test must explicitly wait-for-ready, reset state via Hook API, and verify preconditions via `get_value`/`wait_for_event` rather than assuming a "clean" ImGui state from a prior test. See [../docs/guide_testing.md](../docs/guide_testing.md#authoring-robust-live_gui-tests-dont-assume-clean-state) for the 5-rule authoring contract with anti-pattern vs pattern code examples. Bisect failures by running the test both in the full suite and in isolation to distinguish "test needs work" from "real app bug".
 
+#### Anti-Pattern: `push_event` + `time.sleep(N)` + `assert` is a guaranteed race (Added 2026-06-10)
+
+The pattern `push_event(...)` → `time.sleep(N)` → `assert` is a guaranteed race condition in batched runs. The first time you write this, the test passes in isolation because the sleep happens to be long enough. Then it lands in the batched run, the subprocess is busier, the sleep is no longer long enough, and the assert fires before the GUI render loop has processed the event.
+
+**Fix:** Replace `time.sleep(N)` with a poll loop on `get_value` or `wait_for_event`. The poll doubles as a wait-for-ready AND a correctness assertion.
+
+```python
+# WRONG: race condition
+def test_open_modal(live_gui):
+    client.push_event("custom_callback", {"callback": "_toggle_settings", "args": []})
+    time.sleep(1)  # hope the modal opened
+    assert some_cached_value["settings_open"] is True  # may be stale
+
+# RIGHT: poll-until-state-visible
+def test_open_modal(live_gui):
+    client.push_event("custom_callback", {"callback": "_toggle_settings", "args": []})
+    assert client.get_value("show_settings_modal"), "settings modal did not open"
+```
+
+This pattern surfaced 5+ times in the 2026-06-10 batch-green wave (test_reset_session_clears_mma_and_rag, test_visual_mma, test_visual_sim_gui_ux, test_gui_ux_event_routing, test_z_negative_flows). The fix is always the same: replace `time.sleep` with a poll loop bounded by a retry timeout (typically 5-20 iterations × 0.5s).
+
+#### Async Setters Need Poll-For-State (Added 2026-06-10)
+
+`mma_state_update` and `rag_*` setters operate asynchronously via the `_pending_gui_tasks` queue (`src/app_controller.py:_pending_gui_tasks_lock` and the dispatch logic in `src/gui_2.py:_process_pending_gui_tasks`). The setter returns before the GUI render loop processes the task. Asserting immediately after a setter call is a race.
+
+**Fix:** Poll via `get_value` with a bounded retry loop, not a single `time.sleep`. The setters that need this treatment include (but are not limited to): `mma_state_update`, `rag_enabled`, `rag_source`, `rag_emb_provider`, `rag_chunk_size`, `rag_chunk_overlap`, and any other `set_value` that targets a `_pending_gui_tasks`-dispatched field. See [../docs/guide_testing.md §MMA and RAG State in `reset_session()`](../docs/guide_testing.md) for the full state-bucket list.

 **Prevention:** When reorganizing a class body, run the AST check above immediately after the edit. This catches the issue in <1 second vs. finding it via failing live_gui tests minutes later.
 
+### Isolated-Pass Verification Fallacy (Added 2026-06-09)
+
+A test that "passes when run after test X but fails in isolation" is a **fragile test, not a fragile fixture**. The flip side is also true: a test that "passes in isolation but fails in batch" is failing — its failure is masked by isolation. The only verification that matters for `live_gui` tests (or any test that depends on shared subprocess state) is the **batch run** in the suite the test will ship in.
+
+**Rule:** For any `live_gui` test or any test that depends on shared subprocess state, do NOT commit a fix that you have only verified in isolation. The fix must pass in the batched run that includes the tests that share the subprocess. Run the batch first. If the test fails in batch, your fix is incomplete. Per the existing `Live_gui Test Fragility (Authoring-Side)` rule above, the bisect requires both directions. If you only run in isolation, you cannot tell "test needs work" from "real app bug."
+
+### Process Anti-Patterns (Added 2026-06-09)
+
+These are the bad patterns the agents have been exhibiting that the user explicitly called out. The rules below are short. If you find yourself doing any of these, STOP and reread this section.
+
+For the full rationale on each, see `AGENTS.md` "Process Anti-Patterns." The summary rules:
+
+1. **The Deduction Loop (kill it).** You are allowed to run a failing test at most **2 times** in a single investigation. After the 2nd failure, STOP running the test. Read the code, predict the failure mode, instrument all relevant state in one pass, then run once more. If that fails, report to the user — do not loop.
+2. **The Report-Instead-of-Fix Pattern (kill it).** A 200-line status report is a confession, not a fix. A good status report is 5-10 sentences. Status reports are allowed only when you have actually tried the fix and it failed with evidence, OR you are blocked on a decision the user must make.
+3. **The Scope-Creep Track-Doc Pattern (kill it).** If the user asks for a fix, your output is the fix. A track doc is only appropriate when the fix is multi-day work. If the fix is < 100 lines, it does not get a track. If it would touch more than 5 files, it MIGHT get a track — but ask first.
+4. **The Inherited-Cruft Pattern (kill it).** If the file is already broken from a previous session, the FIRST thing you do is ask the user: "this file is in a broken state from a previous agent. do you want me to (a) revert the working tree and start from a clean baseline, (b) finish the previous agent's intent, or (c) abandon the work entirely?"
+5. **No Diagnostic Noise in Production (kill it).** Diag stderr goes to a log file or a /tmp script, not `src/*.py`. If you must add diag lines to production code, they are part of the same atomic commit as the fix — they do not live uncommitted in the working tree.
+6. **The "I Am Not Going To Attempt Another Fix" Surrender (kill it).** This is correct ONLY if you have already done: read the source, predicted the failure, instrumented state, run once, captured full output. Otherwise you are surrendering too early.
+7. **The Verbose-Commit-Message Pattern (kill it).** A commit message is 1-3 sentences. If it's longer than 15 lines, it's a report, not a commit message. Save the report for `docs/reports/`.
+8. **The Isolated-Pass Verification Fallacy (kill it).** A test that passes in isolation but fails in batch is failing. Verify in batch, not isolation, for any test that touches shared subprocess state.
+9. **The Workspace-Path Drift Pattern (kill it, added 2026-06-09).** Test workspaces live in the project tree under `tests/artifacts/`. Conftest creates them. **Never** use `tmp_path_factory.mktemp` for test infrastructure workspaces (it lives in `%TEMP%` and the user cannot find it). **Never** use env vars for test paths (hidden global state). **Never** add CLI args for test paths (conftest is the right place). The pattern: module-level constant in conftest that computes `Path(f"tests/artifacts/<workspace>_<timestamp>")` at import time. See `conductor/code_styleguides/workspace_paths.md` for the full rule and the 4-day agent churn that led to it.

+## Skip-Marker Policy: Documentation, Not Avoidance
+
+`@pytest.mark.skip(reason=...)` is **documentation of a known failure**, not a way to avoid fixing the underlying bug. Skip markers are useful for:
+
+- **Opt-in integration tests** that require external resources (a real API key, a live provider, a specific env var). Use `@pytest.mark.skipif(...)` with an env-var gate so the test runs when the resource is available and skips by default.
+- **Tests for features that don't exist yet** (planned but not implemented).
+- **Tests for features behind a feature flag** that's currently off.
+
+Skip markers are NOT useful for:
+
+- **Pre-existing failing tests** (a test that "used to pass" or "was supposed to pass but the underlying code regressed"). The underlying code/test should be fixed in-session.
+- **Tests that the agent doesn't understand** ("I don't know how to fix this, so I'll skip it"). Escalate to a Tier 4 QA agent for analysis, or ask the user.
+- **Tests with racy assertions that the agent doesn't want to debug** (e.g., a `time.sleep(0.5)` would fix it). Fix the race, don't skip.
+
+**When you add a skip marker, you MUST also:**
+1. Document the underlying issue in the `reason=` string (one or two sentences).
+2. State what the fix would be (file:line or a one-line description).
+3. Commit the skip with a follow-up note in the commit body that records the underlying issue, so the next agent (or future self after compaction) can find it via `git log --oneline --grep "skip"`.
+
+**When the underlying issue is fixable in-session, FIX IT INSTEAD of adding a skip marker.** Limited context is not an excuse: the agent may not know whether the fix is "important" or "easy" until it tries. A skip marker that never gets revisited is a silent test-suite rot.
+
+**Review checklist before adding a skip marker:**
+- [ ] Is this a known-bad infrastructure issue (env-var gated)? Use `@pytest.mark.skipif` instead.
+- [ ] Is this a feature not yet implemented? If so, the feature should be a TODO, not a skip.
+- [ ] Can the test be fixed in < 30 minutes of investigation? If yes, fix it.
+- [ ] If the fix is too large, is the underlying issue tracked elsewhere (a conductor track, a TODO in the code)?

+## Module-Level Imports
+
+> **Important:** The 5 provider SDKs are **NOT** imported at module level. `import google.genai`, `import anthropic`, `import openai`, and `import fastapi` are heavy (~430-955ms each on cold load) and are now obtained via `src.module_loader._require_warmed("google.genai")` and similar calls, after the `WarmupManager` has loaded them in the background. The module-level globals you see in the State section (`_gemini_client`, `_anthropic_client`, etc.) are typed as `Optional` because they're populated by `_require_warmed()` on first use, not at import time.
+
+This change was part of the 2026-06-06 `startup_speedup_20260606` track. Before: `import src.ai_client` took ~1800ms. After: ~161ms. The remaining cost is the bare module skeleton.

+2. **Did the warmup block the first frame?** — `get_startup_timeline()` returns the 3 phase breakdowns (AppController init, GUI bundle setup, first render) plus the critical gap between warmup completion and first frame paint.
+
+**Client methods** in `ApiHookClient` (`src/api_hook_client.py:312-348`):
+
+| Method | Endpoint | Purpose |
+|---|---|---|
+| `get_warmup_status()` | `GET /api/warmup_status` | Returns `{pending, completed, failed}` |
+| `get_warmup_wait(timeout=30.0)` | `GET /api/warmup_wait?timeout=N` | Server-side blocking wait |
+| `get_warmup_canaries()` | `GET /api/warmup_canaries` | Per-module import timing |
+| `get_startup_timeline()` | `GET /api/startup_timeline` | Phase breakdown dict |
+
+**External script pattern:** A test or script that needs the app fully ready should call `client.get_warmup_wait(timeout=60)` before any other API call. This replaces the old `time.sleep(N)` race-condition pattern. See `tests/test_api_hooks_warmup.py` for usage examples.

-Initializes the controller. Key state:
+> **Important:** The `__init__` does NOT create manager objects, does NOT register hooks, and does NOT start the HookServer. The previous documentation in this section **predated the controller refactor** and described an architecture that was never actually implemented (an `AppState` dataclass, an `enable_test_hooks` parameter, a `register_hooks` method, and manager objects that don't exist on the controller).
 
-```python
+Initializes the controller. Real state created here:
-class AppController:
-    def __init__(self, enable_test_hooks: bool = False):
-        # 1. Path resolution (src/paths.py)
-        self.paths = PathManager()
 
-        # 2. State container
+The actual `__init__` (`src/app_controller.py:778-1212`) does the following:
-        self.app_state = AppState()
 
-        # 3. Subsystem managers
+1. **Startup timeline anchors** — Captures `_init_start_ts` for the `startup_timeline()` diagnostics. Other timeline anchors are filled in lazily as events occur.
-        self.presets = PresetManager(self.paths)
+2. **Locks** — Creates **11** thread-safety locks (`_send_thread_lock`, `_disc_entries_lock`, `_pending_*_lock` for comms/tool_calls/history/gui_tasks/dialog/api_event_queue, `_rag_engine_lock`, `_rag_sync_lock`, `_project_switch_lock`) plus 5 non-lock state fields for the RAG-sync coalescing and project-switch state machine (`_rag_sync_token`/`_rag_sync_dirty`, `_project_switch_in_progress`/`_pending_path`/`_error`).
-        self.personas = PersonaManager(self.paths)
+3. **GUI health state** — `_gui_degraded_reason` and `_last_imgui_assert` (set when `immapp.run` raises `RuntimeError`; see [guide_gui_2.md](guide_gui_2.md#startup-architecture-lazy-imports-profiler-refresh-rate)).
-        self.context_presets = ContextPresetManager(self.paths)
+4. **Shared io_pool** — `make_io_pool()` creates an **8-thread** `ThreadPoolExecutor` named `controller-io-N` (per `IO_POOL_MAX_WORKERS = 8` in `src/io_pool.py:20`; bumped 4→8 in commit `4a338486` on 2026-06-06). This is the SOLE background pool for all async work (no `threading.Thread()` calls anywhere else in `src/`). The module docstring at `src/io_pool.py:1-15` also documents the SIGINT-handler fix that replaced the original atexit approach.
-        self.tool_presets = ToolPresetManager(self.paths)
+5. **Warmup manager** — `WarmupManager(self._io_pool, log_to_stderr=log_to_stderr)` with an on-complete callback to stamp `warmup_done_ts`. `defer_warmup=True` defers the actual `start_warmup()` call until the first frame is painted (the desktop GUI pattern; headless mode starts immediately). The `log_to_stderr` parameter honors `SLOP_WARMUP_DEBUG` env var.

+2. `src/api_hooks.py:HookHandler.do_GET` / `do_POST` reads from these registries to expose App methods as `/api/gui` `custom_callback` actions.
+3. The `sloppy.py` CLI parses `--enable-test-hooks` and passes it to `HookServer` (a separate class, not the controller).

 ## Hot Reload
 
-The controller can hot-reload Python modules while preserving state. This is critical for GUI iteration:
+Hot reload is wired in `src/gui_2.py` rather than on the controller. The actual mechanism:
 
-```python
+- **Registration** (`src/gui_2.py:282-287`): `App.__init__` registers `src.gui_2` with `HotReloader`, listing the App attributes (`state_keys`) to snapshot before reload and the App wrapper methods (`delegation_targets`) that the delegation pattern swaps atomically.
-def hot_reload(self, module_name: str) -> None:
+- **Trigger** (`src/gui_2.py:540-544`): `App._trigger_hot_reload()` calls `HotReloader.reload_all(self)` and stores `HotReloader.last_error` on `self._hot_reload_error` for visual error feedback.
-    """Reload a module and re-apply its render functions to the app."""
+- **Keyboard binding** (`src/gui_2.py:5340-5346`): the `Ctrl+Alt+R` shortcut is hard-coded in the source — there is no `config.toml` key for it.
-    from src.hot_reload import HotReloader
-    reloader = HotReloader(self.app)
-    reloader.reload(module_name)
-```
 
-`gui_2.py` registers all its render functions with the reloader at startup. On reload, the reloader swaps the function references without losing app state.
+`HotReloader` is a stateless class (classmethods only); it has no constructor and no `self.app` field. See **[docs/guide_hot_reload.md](guide_hot_reload.md)** for the full mechanism.

+- The `_toggle_window(app, "<window name>")` calls are case-sensitive against the keys of `app.show_windows` (the per-window visibility dict on the App).
+- The category column is editorial — the registry stores no category; the title is what's actually searched in the palette.

+
+## Overview
+
+`src/aggregate.py` (518 lines) is the **context composition pipeline** — the single function that turns a project's `files` + `screenshots` + `history` config into the final markdown string the AI sees. It is called by:
+
+- `src/ai_client.py:_send_anthropic`, `_send_deepseek`, `_send_gemini`, `_send_gemini_cli`, `_send_minimax` (every provider)
+- `src/app_controller.py:AppController._do_generate` (the main send path)
+- `src/app_controller.py:AppController._cb_start_track`, `AppController._process_event_queue`, `AppController._start_track_logic` (MMA paths)
+- `src/gui_2.py:App.run`, `App.main`, `App._render_snapshot_tab` (the GUI and the prior-session replay)
+- `simulation/sim_base.py:run_sim` and 6 other simulation entry points
+
+This is one of the most-touched modules in the project. After the nagent_review, this pipeline is recognized as **Manual Slop's strongest curation dimension** (vs nagent's conversation-log dimension). See `conductor/tracks/nagent_review_20260608/report.md §6` and `decisions.md` candidate #7 for the related future-track.
+
+> **Domain classification.** The pipeline is **Application**-domain. The MMA sub-agents consume it but the pipeline itself does not call into Meta-Tooling code. See `guide_meta_boundary.md`.

+```
+
+The **output** is a markdown file at `{output_dir}/{namespace}_{NNN}.md` where `NNN` is a zero-padded increment. The pipeline does not *send* the markdown — that's the AI client's job. The pipeline *produces* the markdown.
+
+The **return value** is `(markdown: str, output_file: Path, file_items: list[dict])`. The file_items list is reused by callers that want to inspect the read state without re-reading from disk.
+
+---
+
+## The Three Aggregation Strategies
+
+`aggregation_strategy: str` selects how files are rendered. The values:
+
+| Strategy | File rendering | History rendering | Tier 3 handling | Use case |
+|---|---|---|---|---|
+| `auto` | If `summary_only` is True → summary; else → full | Standard | Standard | Default. Reads `config.project.summary_only`. |
+| `summarize` | Always `summarize.build_summary_markdown(file_items)` (compact multi-file view) | Standard | Standard | Token-budget-constrained runs. |
+| `full` | Always `_build_files_section_from_items(file_items)` (full content) | Standard | Standard | Debugging; when you want the AI to see everything. |
+
+**Implementation:** `aggregate.py:330-346 build_markdown_from_items`. The three-way dispatch is at lines 335-339:
+
+```python
+if   aggregation_strategy == "summarize": parts.append("## Files (Summary)\n\n" + summarize.build_summary_markdown(file_items))
+elif aggregation_strategy == "full":      parts.append("## Files\n\n"           + _build_files_section_from_items(file_items))
+else: # auto
+    if summary_only: parts.append("## Files (Summary)\n\n" + summarize.build_summary_markdown(file_items))
+    else:            parts.append("## Files\n\n"           + _build_files_section_from_items(file_items))
+```
+
+The `auto` strategy is the *only* one that respects `config.project.summary_only`; the other two are explicit overrides. Personas can also set `aggregation_strategy` (per `guide_personas.md`), and a persona-set strategy overrides the config-level setting.
+
+---
+
+## View Modes — The Per-File Transform
+
+`view_mode: str` is the per-file content transform. The value is set on the `FileItem` (or the legacy dict-shaped config entry) and determines how the file's bytes are rendered into the markdown.
+
+| View mode | Behavior | Source |
+|---|---|---|
+| `full` | Raw `path.read_text(encoding="utf-8")` content. | `aggregate.py:205` |
+| `summary` | `summarize.summarise_file(path, content)` — heuristic summary from `src/summarize.py`. | `aggregate.py:210` |
+| `skeleton` | For `.py`: `ASTParser("python").get_skeleton(content)` (tree-sitter). For `.c`/`.h`: `mcp_client.ts_c_get_skeleton`. For `.cpp`/`.hpp`: `mcp_client.ts_cpp_get_skeleton`. Other → summary. | `aggregate.py:211-220` |
+| `outline` | For `.py`: `ASTParser("python").get_code_outline(content)`. For C/C++: `mcp_client.ts_c*_get_code_outline`. Other → summary. | `aggregate.py:221-230` |
+| `masked` | For each `{symbol: mode}` in `ast_mask`, fetch `def` or `sig` via `mcp_client.py/ts_*_get_definition/signature`. Concatenate. | `aggregate.py:231-249` |
+| `none` | Literal string `"(context excluded)"` — the file is in the file_items list but contributes no content. | `aggregate.py:250` |
+| `custom` | Render only the `custom_slices` from the FileItem. Each slice is a `{start_line, end_line, tag, comment}` dict. Lines outside the slices are excluded. | `aggregate.py:251-266` |
+
+**The default view mode** is `full`. The persona can override via `Persona.aggregation_strategy`; the FileItem can override via `FileItem.view_mode` or `FileItem.force_full` (which forces `full` regardless of the FileItem's own setting).
+
+**Errors are graceful.** A `FileNotFoundError` produces `f"ERROR: file not found: {path}"` content with `error: True` and `mtime: 0.0`. A `view_mode` that throws produces `f"ERROR in {view_mode} view mode for {path}:\n{traceback.format_exc()}"`. Errors do not halt the pipeline.
+
+---
+
+## The FileItem Schema (Full)
+
+`src/models.py:510-559 FileItem` is the **per-file curation memory** that nagent_review identified as Manual Slop's strongest dimension. The dataclass has 9 mutable fields + a `__post_init__` normalizer:
+
+```python
+@dataclass
+class FileItem:
+    path:            str                # the artifact identity (path-keyed, no inode)
+    auto_aggregate:  bool = True       # include in auto-aggregation? (skip in build_*_from_items if False)
+    force_full:      bool = False      # bypass view_mode; force raw content
+    view_mode:       str = 'full'      # one of: full, summary, skeleton, outline, masked, custom, none
+    selected:        bool = False      # for batch operations (the Context Panel multi-select)
+    ast_signatures:  bool = False      # include only signatures (skeleton-equivalent shortcut)
+    ast_definitions: bool = False      # include only definitions (skeleton-equivalent shortcut)
+    ast_mask:        dict[str, str]    # per-symbol mask: {symbol_path: 'def'|'sig'|'hide'} (from Structural File Editor)
+    custom_slices:   list[dict]        # Fuzzy Anchor slices: {start_line, end_line, tag, comment, ...}
+    injected_at:     Optional[float]   # timestamp of last injection
+```
+
+The 9 fields are *all* serialized by `to_dict()` and *all* deserialized by `from_dict()` (with `.get(..., default)` for forward compatibility). The dataclass is round-trip-safe through TOML.
+
+`__post_init__` normalizes `custom_slices`: each slice dict gets `tag=None` and `comment=None` defaults added so downstream code can `.get("tag")` safely.
+
+### The Custom Slice Schema
+
+A `custom_slices` entry is `{start_line, end_line, tag, comment, ...}` (plus Fuzzy Anchor metadata). The full schema is in `src/fuzzy_anchor.py:FuzzyAnchor.create_slice`:
+
+```python
+{
+    "start_line":  int,        # 1-based original line
+    "end_line":    int,        # 1-based original line (inclusive)
+    "tag":         str|None,   # human label, defaults to None
+    "comment":     str|None,   # human comment, defaults to None
+    "content_hash": str,       # SHA-256 of the slice content (for Fuzzy Anchor stability)
+    "anchor_lines": [str, ...],# surrounding context for re-resolution
+    # plus the original positioning metadata
+}
+```
+
+When `view_mode == 'custom'`, the `aggregate.py:251-264` block renders each slice as:
+
+```markdown
+---
+[Slice: <tag>] (<comment>)
+Lines <start>-<end>:
+<content>
+```
+
+Multiple slices in a file are joined with `\n\n`.
+
+---
+
+## The ContextPreset Schema
+
+`src/models.py:909-937 ContextPreset` is a *named, persisted set* of `FileItem`s — a reusable "context composition":
+
+```python
+@dataclass
+class ContextPreset:
+    name:        str                                  # the preset name (used as TOML key)
+    files:       list[ContextFileEntry] = field(default_factory=list)
+    screenshots: list[str] = field(default_factory=list)
+    description: str = ""
+```
+
+`ContextFileEntry` is a `FileItem` (or a string path that's promoted to a `FileItem` on load). The `description` is a human-readable label for the preset list.
+
+`ContextPresetManager` (in `src/context_presets.py`, 30 lines) handles CRUD:
+- `save_preset(preset: ContextPreset)` writes to `manual_slop.toml` or a project TOML
+- `load_all() -> dict[str, ContextPreset]` reads all presets
+- `delete_preset(name: str)` removes a preset
+- `apply_preset(name: str)` switches the active context composition to the named preset
+
+`reload_context_presets()` (in `app_controller.py`) is called when the project TOML changes; it validates that all files in the preset still exist and warns the user about any that don't.
+
+**Scope:** ContextPresets can be **Global** (in `<user_config>/manual_slop.toml`) or **Project-specific** (in the project's `manual_slop.toml`). Project presets override global presets of the same name. This is the same scope-inheritance pattern as Personas, Presets, and Workspace Profiles.
+
+---
+
+## The Discussion History Section
+
+`aggregate.py:109 build_discussion_section(history)` is the section that includes the prior conversation:
+
+```python
+def build_discussion_section(history: list[Any]) -> str:
+    sections = []
+    for i, entry in enumerate(history, start=1):
+        if isinstance(entry, dict):
+            role    = entry.get("role", "Unknown")
+            content = entry.get("content", "").strip()
+            text    = f"{role}: {content}"
+        else:
+            text = str(entry).strip()
+        sections.append(f"### Discussion Excerpt {i}\n\n{text}")
+    return "\n\n---\n\n".join(sections)
+```
+
+The section handles *both* legacy `list[str]` (e.g. `["User: ...", "AI: ..."]`) and the new `list[dict]` shape (`[{"role": ..., "content": ...}, ...]`). The dict shape is what's persisted by `_flush_disc_entries_to_project` (per `app_controller.py:3225-3240`) and what's stored in the new format.
+
+The section is named **`## Discussion History`** and is placed at the *end* of the markdown (after files, screenshots, beads). This is deliberate: the cache-hit-friendly static prefix is at the top, the dynamic history is at the bottom. See `guide_architecture.md §"Cache Strategy"`.
+
+---
+
+## Cache Strategy
+
+The pipeline is structured to maximize provider cache hits. The static prefix (Files + Screenshots + Beads) is the same across all turns of a discussion; only the Discussion History changes. The provider's cache key is the prefix; the history is appended.
+
+`build_markdown_no_history` (`aggregate.py:348-353`) is the explicit "static-only" builder used by `_do_generate` *before* adding the history. The full builder is `build_markdown_from_items` which adds the history if non-empty. This split allows the AI client to:
+
+1. Send the static prefix once.
+2. Append the history to the next send without re-sending the prefix.
+3. Re-use the cached prefix on the third send (if the files haven't changed).
+
+The cache strategy is documented in detail in `guide_ai_client.md §"Caching Strategy"` and `guide_architecture.md §"Cache Hit Strategy"`.
+
+---
+
+## The Tier-3 Variant
+
+`aggregate.py:364-454 build_tier3_context` is the **MMA worker context** — a different layout for sub-agent invocations. The differences from the standard pipeline:
+
+1. **Focus files** (passed as `focus_files: list[str]`) are rendered as **full content** regardless of their `view_mode`. A file is a focus file if its `entry`, name, or path matches one of the focus paths.
+2. **Slices are resolved via FuzzyAnchor.** If a file has `custom_slices` and the file content has been modified since the slice was created, the FuzzyAnchor re-resolves the line ranges. This is critical for sub-agents receiving slices that may be stale.
+3. **Section header is `## Files (Tier 3 - Focused)`.** Distinct from the standard `## Files` so the worker (and its tools) can recognize its own context.
+4. **The `is_focus` check is multi-level.** Entry match, name match, path match, and substring match. Sub-agents with looser file-matching needs can pass a focus set that's just a list of basenames.
+
+The Tier 3 build skips the `summarize.build_summary_markdown` path entirely; every file is rendered with `_build_files_section_from_items`-style formatting (or the AST skeleton for non-focus Python files, or the AST signature/outline for C/C++).
+
+The Tier 3 build is called from `multi_agent_conductor.py:run_worker_lifecycle` via `aggregate.run(config, aggregation_strategy=tier_strategy)`.
+
+---
+
+## The Bypass — `force_full`
+
+`FileItem.force_full = True` short-circuits the `view_mode` selection:
+
+```python
+if force_full: view_mode = "full"
+```
+
+This is set at the `FileItem` level (not the strategy level). Use case: the user has set a global "skeleton" view mode for the project but wants one specific file to always be inlined in full. The force is per-file and overrides both the FileItem's own `view_mode` and any strategy-level override.
+
+For Tier 3, `force_full` is treated as a *focus flag*:
+
+```python
+if is_focus or tier == 3 or force_full:
+    # full content, no skeleton
+```
+
+So a `force_full=True` file in a Tier 3 worker context is treated as a focus file and rendered in full.
+
+---
+
+## Auto-Aggregate Skip
+
+`FileItem.auto_aggregate = False` causes the file to be *included in the file_items list* but *excluded from the rendered markdown*:
+
+```python
+for item in file_items:
+    if not item.get("auto_aggregate", True): continue
+    # ... build section
+```
+
+Use case: the file is in the `files` list for the AI's *awareness* (e.g. "you can read it via `read_file`") but should not be inlined. The file's `mtime` and `view_mode` are still tracked; the file is *omitted* from the rendered markdown.
+
+This is distinct from `view_mode == "none"`:
+- `auto_aggregate = False` → file is not in the rendered markdown at all (no `### File` header)
+- `view_mode = "none"` → file is in the rendered markdown as `### File (excluded)` with a `"(context excluded)"` body
+
+The two are useful for different scenarios. `auto_aggregate = False` is for "the AI knows the file exists, can read it on demand." `view_mode = "none"` is for "the AI knows we deliberately excluded this content."
+
+---
+
+## Screenshots
+
+`aggregate.py:126-140 build_screenshots_section` renders the screenshots list as a `## Screenshots` markdown section. Each screenshot is rendered as `![name](path)` (markdown image syntax). Path resolution uses `resolve_paths` (same as for files), so wildcards and absolute paths work.
+
+**Screenshots are placed *after* Files and *before* Beads and Discussion History.** This is a deliberate ordering: the AI sees the project's files first (the static content), then the screenshots (the visual context), then the beads status (if applicable), then the discussion history (the dynamic content).
+
+---
+
+## Beads Mode
+
+When `execution_mode == "beads"` (set in `config.project.execution_mode`), the pipeline appends a `## Beads Mode: Progress Track` section between Screenshots and Discussion History. The section is built by `aggregate.py:309-328 build_beads_section`:
+
+- Lists all *completed* beads as a comma-separated list
+- Lists all *active* beads as bullet points with title, id, and description
+
+`build_beads_section` returns an empty string if the project is not a Beads project (`client.is_initialized()` is False) or if there are no beads. The caller (`build_markdown_from_items`) checks the truthiness before appending.
+
+See `guide_beads.md` for the full Beads integration.
+
+---
+
+## Output File Numbering
+
+`find_next_increment(output_dir, namespace)` (`aggregate.py:36-44`) scans `output_dir` for files matching `^{namespace}_(\d+)\.md$` and returns `max_num + 1`. The output filename is `{namespace}_{NNN:03d}.md` (zero-padded to 3 digits). The increment starts at 1 and grows monotonically.
+
+The increment is the *artifact identity* for the conversation. Each turn produces a new file. The current implementation does *not* delete old files; the `LogPruner` (per `guide_architecture.md`) handles cleanup separately.
+
+---
+
+## Pipeline Callers
+
+`aggregate.run` is called from many places. The most important:
+
+| Caller | Purpose |
+|---|---|
+| `src/ai_client.py:_send_anthropic` | Build the markdown for an Anthropic send. |
+| `src/ai_client.py:_send_gemini` | Build the markdown for a Gemini send. |
+| `src/ai_client.py:_send_deepseek` | Build the markdown for a DeepSeek send. |
+| `src/ai_client.py:_send_gemini_cli` | Build the markdown for a Gemini CLI send. |
+| `src/ai_client.py:_send_minimax` | Build the markdown for a MiniMax send. |
+| `src/app_controller.py:AppController._do_generate` | The main 1:1 send path. |
+| `src/app_controller.py:AppController._cb_start_track` | Start a new MMA track. |
+| `src/app_controller.py:AppController._process_event_queue` | Process a queued event (e.g. send, switch discussion). |
+| `src/multi_agent_conductor.py:run_worker_lifecycle` | Spawn a Tier 3 worker (with Tier 3 context). |
+| `src/gui_2.py:App.run` | The main GUI loop. |
+| `src/gui_2.py:App._render_snapshot_tab` | Render a prior-session replay snapshot. |
+| `simulation/sim_base.py:run_sim` | Run a simulation. |
+
+The aggregation strategy is set per-call:
+- The main `_do_generate` uses `config.project.aggregation_strategy` (which is the persona-set strategy if a persona is active).
+- MMA worker contexts use the worker's `aggregation_strategy` from the ticket config.
+- The simulation uses a fixed `auto`.
+
+---
+
+## Public API Surface
+
+The public API of `aggregate.py` is:
+
+| Function | Signature | Purpose |
+|---|---|---|
+| `find_next_increment` | `(output_dir: Path, namespace: str) -> int` | Next file number for output. |
+| `resolve_paths` | `(base_dir: Path, entry: str) -> list[Path]` | Expand globs and absolute paths. Blacklist `history.toml` and `*_history.toml`. |
+| `group_files_by_dir` | `(files: list[Any]) -> dict[str, list[Any]]` | Group FileItems by relative directory path (used by the Context Panel UI). |
+| `compute_file_stats` | `(abs_path: str) -> dict[str, int]` | Line count + AST element count for Python files. |
+| `build_file_items` | `(base_dir, files) -> list[dict]` | Read + view-mode transform per file. The most-called function. |
+| `build_discussion_section` | `(history) -> str` | Render the `## Discussion History` markdown. |
+| `build_screenshots_section` | `(base_dir, screenshots) -> str` | Render the `## Screenshots` markdown. |
+| `build_beads_section` | `(base_dir) -> str` | Render the `## Beads Mode: Progress Track` markdown. |
+| `build_markdown_from_items` | `(file_items, screenshot_base_dir, screenshots, history, summary_only, aggregation_strategy, execution_mode, base_dir) -> str` | Compose all sections. The "compose" function. |
+| `build_markdown_no_history` | `(file_items, screenshot_base_dir, screenshots, summary_only, aggregation_strategy) -> str` | Compose without history (for stable caching). |
+| `build_discussion_text` | `(history) -> str` | Just the history section, for callers that want to append to a pre-built static prefix. |
+| `build_tier3_context` | `(file_items, screenshot_base_dir, screenshots, history, focus_files) -> str` | Tier 3 worker context. |
+| `build_markdown` | `(base_dir, files, screenshot_base_dir, screenshots, history, summary_only, execution_mode) -> str` | Convenience: read files + compose. |
+| `run` | `(config, aggregation_strategy) -> tuple[str, Path, list[dict]]` | The full pipeline. |
+| `main` | `() -> None` | CLI entry point. Loads config, calls `run`, prints output path. |
+
+**Performance:** the entire pipeline is O(N) in the number of files, with the per-file AST work being the most expensive step. `build_tier3_context` includes `with get_monitor().scope("build_tier3_context")` (and similar for `build_file_items` and `build_markdown_no_history`) for performance monitoring. The monitor is documented in `guide_architecture.md §"Performance"`.
+
+---
+
+## Performance Considerations
+
+The `view_mode` selection has a meaningful performance impact:
+
+| view_mode | Per-file cost | When to use |
+|---|---|---|
+| `full` | 1 file read + string concat | Small files, files the user is actively editing. |
+| `summary` | 1 file read + 1 heuristic call to `summarize.summarise_file` | Large files where structural info is enough. |
+| `skeleton` | 1 file read + 1 tree-sitter parse + skeleton build | Python/C/C++ files where the structure matters more than the content. |
+| `outline` | 1 file read + 1 tree-sitter parse + outline build | When the AI only needs the public API surface. |
+| `masked` | 1 file read + N `mcp_client.py/ts_*_get_*` calls (one per masked symbol) | When the user has explicitly marked symbols as "def" or "sig". |
+| `none` | 1 file read (still reads the bytes, just discards) | When the user wants the file in the list but not in the rendered markdown. |
+| `custom` | 1 file read + line slicing per slice | When the user has explicitly created Fuzzy Anchor slices. |
+
+The `force_full = True` and `auto_aggregate = False` flags skip *some* of the work:
+- `force_full = True` skips the view-mode dispatch and goes straight to raw content.
+- `auto_aggregate = False` skips the view-mode dispatch entirely and skips the markdown section build.
+
+For very large codebases (1000+ files), the bottleneck is the tree-sitter parsing for `skeleton` / `outline` / `masked` modes. The Tier 3 builder uses `ASTParser("python")` lazily (`if not parser: parser = ASTParser("python")`) so the tree-sitter grammar is loaded only once per pipeline call.
+
+---

+# Discussions: Takes, Branching, and Per-Entry Editing
+
+[Top](../Readme.md) | [App Controller](guide_app_controller.md) | [GUI Main](guide_gui_2.md) | [Models](guide_models.md)
+
+---
+
+## Overview
+
+A **Discussion** is Manual Slop's first-class unit of conversation. Every prompt the user types, every AI response, every tool result, every per-entry edit lives in a Discussion. Discussions are persisted to the project's TOML as a typed list of entries; they can be branched into multiple **Takes**, switched between, renamed, deleted, and (most importantly) **edited at the entry level** by the user in the GUI.
+
+The discussion system is one of the *most-edited* surfaces in Manual Slop. The user can:
+
+- **Edit any entry's text** in place (full multi-line edit, not just inline)
+- **Insert new entries** at any position
+- **Delete any entry** by position
+- **Change the role** of any entry
+- **Branch** at any entry to create a new Take
+- **Undo/redo** every edit (Ctrl+Z / Ctrl+Y)
+- **Promote** a Take to a top-level discussion
+
+This is a *deliberate* design choice. Manual Slop treats the discussion as user-editable working state, not as opaque chat history. The full operation matrix and the rationale are in `conductor/tracks/nagent_review_20260608/report.md §3`; this guide covers the *implementation*.
+
+> **Domain classification.** The discussion system is purely **Application**-domain. It owns no Meta-Tooling concerns; it does not call into `scripts/mma_exec.py`; it is consumed by the GUI and the headless controller, and projected to the AI client. See `guide_meta_boundary.md` for the Application vs Meta-Tooling split.
+
+---
+
+## Data Model
+
+### The Entry Dict
+
+The smallest unit of a discussion is the **entry**, a `dict[str, Any]` with this shape (`src/models.py:parse_history_entries` builds it; `src/gui_2.py:render_discussion_entry` reads it):
+
+| Field | Type | Source | Purpose |
+|---|---|---|---|
+| `role` | `str` | `parse_history_entries` | The speaker. Defaults to one of `["User", "AI", "Vendor API", "System"]` (set in `models.py:208`), but `disc_roles` is user-editable so this can be any string. |
+| `content` | `str` | user input / LLM response | The entry's text. Fully editable in the GUI. |
+| `collapsed` | `bool` | GUI render state | Whether the entry is collapsed to a 60-char preview. Defaults `True`. |
+| `ts` | `str` | `project_manager.now_ts()` | ISO timestamp, prefixed with `@` in the persisted form. |
+| `thinking_segments` | `list[dict]` | `src/thinking_parser.py` | AI entries with `<thinking>` blocks have the blocks parsed out into collapsible segments. |
+| `usage` | `dict` | `ai_client.send()` | Token accounting: `{"input_tokens": N, "output_tokens": N, "cache_read_input_tokens": N}`. |
+| `read_mode` | `bool` | GUI render state | If `True`, render as Markdown; if `False` (default), render as editable text input. |
+
+An entry dict is *open*: extra keys are allowed and ignored by the renderer. This is intentional — the user can add custom metadata via the Hook API or by editing the project TOML directly.
+
+### The Discussion Dict
+
+A **Discussion** is a `dict[str, Any]` under `project.discussion.discussions[<name>]`:
+
+```python
+{
+    "history":              [str, ...]   # legacy: list of "Role: content" strings
+                                   #      OR
+                                   # list of entry dicts (new format)
+    "git_commit":           str,         # git SHA at the time the discussion was last updated
+    "last_updated":         str,         # ISO timestamp
+    "context_snapshot":     [dict, ...], # list of FileItem.to_dict() at send time
+    "sent_markdown":        str,         # the actual markdown sent to the AI on the last send
+    "sent_system_prompt":   str,         # the system prompt that was active at send time
+}
+```
+
+The `project_manager.default_discussion()` factory returns a fresh dict with empty `history` and the standard keys. `app_controller._switch_discussion` reads the dict, parses `history` via `models.parse_history_entries(history_strings, self.disc_roles)`, and writes the live `disc_entries` list.
+
+### The Take Naming Convention
+
+Takes are encoded in the discussion name. A Take's name has the shape `<base>_take_<n>`. Example: a discussion named `refactor_auth` can have takes `refactor_auth_take_1`, `refactor_auth_take_2`, etc. The `_get_discussion_names` accessor groups by base name (`name.split("_take_")[0]`) so the GUI can render them as nested tabs.
+
+The `_branch_discussion(index)` method (in `app_controller.py:3503`) generates a unique Take name by incrementing `<base>_take_<counter>` until it finds an unused name, then calls `project_manager.branch_discussion(self.project, self.active_discussion, new_name, index)`.
+
+---
+
+## Per-Entry Operations (the A1-A7 matrix)
+
+This is the operation set the user has *per individual entry*. Renderer: `src/gui_2.py:3770 render_discussion_entry(app, entry, index)`.
+
+| # | Operation | GUI control | Source code | What it does |
+|---|---|---|---|---|
+| A1 | **Edit content in place** | `imgui.input_text_multiline` on the entry body | `gui_2.py:3841` | `entry["content"]` is a fully editable multi-line text input. The user can rewrite an AI's response, fix a typo in their own prompt, paste in code from another source, etc. |
+| A2 | **Toggle read/edit mode** | `[Edit]` / `[Read]` button | `gui_2.py:3799` | When in `[Read]` mode, the content is rendered as Markdown with syntax highlighting (`render_discussion_entry_read_mode` at `gui_2.py:3855`). When in `[Edit]` mode, the multi-line text input is shown. |
+| A3 | **Toggle collapsed/expanded** | `+/-` button per entry | `gui_2.py:3789` | Collapsed entries show a 60-char preview (line 3822-3824). Expanded entries show full content. |
+| A4 | **Change role** | Combo box from `app.disc_roles` | `gui_2.py:3793-3796` | The entry's `role` field is editable. The list `app.disc_roles` is itself user-managed (see §"Role Management" below). |
+| A5 | **Insert entry before this one** | `Ins` button | `gui_2.py:3813` | `app.disc_entries.insert(index, {"role": "User", "content": "", "collapsed": True, "ts": project_manager.now_ts()})` |
+| A6 | **Delete this entry** | `Del` button | `gui_2.py:3815-3816` | `if entry in app.disc_entries: app.disc_entries.remove(entry)`. The membership check matters — ImGui can re-render stale state, so the check guards against double-delete. |
+| A7 | **Branch at this entry** | `Branch` button | `gui_2.py:3821` → `app._branch_discussion(index)` → `app_controller._branch_discussion:3503` → `project_manager.branch_discussion:429` | Creates a new Take named `<base>_take_<n>` and copies the history up to and including `index` into the new Take. The user is then switched to the new Take. |
+
+**Why this matrix is load-bearing.** Every entry is independently editable. There is no "edit the whole discussion as one operation." This is the design difference vs. most chat UIs: when an AI's response is wrong, the user can *fix the response text* without losing the entry's role, timestamp, usage accounting, or thinking segments. The AI on the *next* turn sees the corrected response (because the entry's `content` is the source for `build_discussion_section` in `aggregate.py:109`).
+
+---
+
+## Discussion-Level Operations (the B1-B11 matrix)
+
+These are the second-tier controls, rendered at `src/gui_2.py:4239 render_discussion_entry_controls(...)` and the discussion selector at `gui_2.py:4330 render_discussion_selector(...)`.
+
+| # | Operation | GUI control | Source code | What it does |
+|---|---|---|---|---|
+| B1 | **Append new entry** | `+ Entry` button | `gui_2.py:4240` | `app.disc_entries.append({...})` with the default role from `app.disc_roles[0]`. |
+| B2 | **Collapse all / Expand all** | `-All` / `+All` buttons | `gui_2.py:4242-4246` | Bulk-set `collapsed` flag on every entry. |
+| B3 | **Clear all** | `Clear All` button | `gui_2.py:4248` | `app.disc_entries.clear()`. Note: this clears the *current* take, not all takes. |
+| B4 | **Save (flush to project TOML)** | `Save` button | `gui_2.py:4250` | `app._flush_to_project(); app._flush_to_config(); app.save_config()`. |
+| B5 | **Add/remove roles** | `Add` / `X` buttons under "Roles" | `gui_2.py:4317-4328` | `app.disc_roles.append(r)` / `app.disc_roles.pop(i)`. |
+| B6 | **Switch active discussion** | Discussion combo + Take tabs | `gui_2.py:4197, 4344, 4354` | `app._switch_discussion(name)`. Takes group by base name and render as nested tabs. |
+| B7 | **Rename / Delete discussion** | `Rename` / `Delete` buttons | `gui_2.py:4291, 4293` | `app._rename_discussion(...)` / `app._delete_discussion(...)`. Cannot delete the last discussion (guarded at `app_controller.py:3543`). |
+| B8 | **Promote Take to top-level** | `Promote` button in takes panel | `gui_2.py:4364` | `project_manager.promote_take(app.project, app.active_discussion, new_name)` — renames a Take (e.g. `T0_take_2`) to a fresh top-level discussion name. |
+| B9 | **Per-role filter** | `ui_focus_agent` selector (system-wide) | `gui_2.py:4230-4234` | `display_entries = [e for e in app.disc_entries if e.get("role") == persona_name or e.get("role") == "User"]`. The filter follows the MMA persona focus. |
+| B10 | **Truncate to N pairs** | `Truncate` button + `drag_int` | `gui_2.py:4254-4260` | `truncate_entries(app.disc_entries, app.ui_disc_truncate_pairs)` keeps the last `N` User/AI pairs (per `gui_2.py:175 truncate_entries(...)`). |
+| B11 | **Compress (AI summarization)** | `Compress` button | `gui_2.py:4252` → `app_controller._handle_compress_discussion:3357` | Calls `ai_client.run_discussion_compression(disc_text)` and replaces the discussion with the LLM's compressed version. |
+
+---
+
+## Role Management
+
+`app.disc_roles: list[str]` is the master list of valid role strings. It's:
+
+- **Populated from** `models.parse_history_entries`'s default `["User", "AI", "Vendor API", "System"]` (`models.py:208`)
+- **Persisted as** `manual_slop.toml [discussion].disc_roles` (or a project TOML equivalent)
+- **Loaded by** `app_controller.init_state` from the project dict
+
+The user can add or remove roles at runtime via `gui_2.py:4317-4328 render_discussion_roles`. The `Add` button takes `app.ui_disc_new_role_input`, strips it, and appends if not already present. The `X` button pops by index.
+
+A role can be any string — Manual Slop doesn't enforce a vocabulary. Typical custom roles include `Context`, `Tool`, `CodeBlock`, `Error`, `Warning`, or per-project names like `Architect` vs `Implementer`.
+
+The **default role** for new entries is `app.disc_roles[0] if app.disc_roles else "User"`. If the role list is empty, the system falls back to `"User"`. This is intentionally permissive — empty role list is never an error.
+
+---
+
+## Take Lifecycle
+
+### Branch
+
+`app_controller._branch_discussion(index)` (`app_controller.py:3503-3519`):
+
+1. Flush current `disc_entries` to project TOML via `_flush_disc_entries_to_project` (so we don't lose unsaved edits).
+2. Compute the base name: `self.active_discussion.split("_take_")[0]`.
+3. Generate a unique take name: `<base>_take_<counter>` incremented until unused.
+4. Call `project_manager.branch_discussion(self.project, self.active_discussion, new_name, index)`.
+5. Switch the active discussion to the new take via `_switch_discussion(new_name)`.
+
+`project_manager.branch_discussion` (`project_manager.py:429`) does the actual copy:
+- Reads the source discussion
+- Creates a fresh discussion dict with `default_discussion()`
+- Copies the source's `git_commit` (so the new take is anchored to the same code state)
+- Copies `source_disc["history"][:message_index + 1]` — i.e. **all entries up to and including `index`**
+- Sets the new take as active
+
+**Why "up to and including"?** Branching at entry N means "the future starts from entry N's state." The user is saying "from here, what if I had asked a different follow-up?" The AI sees entries 0..N as the prior conversation; entries N+1..end are discarded (in this take — they're still in the parent take, accessible via the Take tabs).
+
+### Promote
+
+`project_manager.promote_take` (`project_manager.py:447`):
+
+- Renames a take to a fresh top-level name
+- Updates the `active` pointer if the renamed take was active
+- Use case: a Take that turned out to be the "real" conversation gets renamed away from the `_take_<n>` suffix to become a first-class discussion
+
+### Switch
+
+`app_controller._switch_discussion(name)` (`app_controller.py:3199`):
+
+1. Flush the current `disc_entries` to the project TOML.
+2. Look up the new discussion in `self.project["discussion"]["discussions"]`.
+3. Set `self.active_discussion = name` and `self._track_discussion_active = False`.
+4. **Atomically** (under `_disc_entries_lock`) replace `self.disc_entries[:] = models.parse_history_entries(disc_data.get("history", []), self.disc_roles)`.
+5. Restore the context snapshot from `disc_data["context_snapshot"]` if present.
+6. Update `ai_status = f"discussion: {name}"`.
+
+The atomic slice-replacement is critical: a renderer that reads `self.disc_entries` mid-update would see a half-empty list. The lock ensures the renderer only sees the old list (before) or the new list (after), never an in-between state.
+
+### Rename / Delete
+
+`_rename_discussion(old, new)` (`app_controller.py:3521`):
+
+- `discussions[new_name] = discussions.pop(old_name)` — atomically swaps the key
+- Updates `active_discussion` and the `active` pointer if the renamed discussion was active
+- Rejects the rename if `new_name` is already in use (`ai_status = f"discussion '{new_name}' already exists"`)
+
+`_delete_discussion(name)` (`app_controller.py:3537`):
+
+- Refuses to delete the last remaining discussion (guarded at line 3543)
+- Removes the discussion from the dict
+- If the deleted discussion was active, switches to the first remaining sorted-by-name discussion
+
+---
+
+## Per-Role Filter (the MMA Link)
+
+`gui_2.py:4227-4237 render_discussion_entries` filters the entry list when `app.ui_focus_agent` is set:
+
+```python
+if app.ui_focus_agent:
+    tier_usage = app.mma_tier_usage.get(app.ui_focus_agent)
+    if tier_usage:
+        persona_name = tier_usage.get("persona")
+        if persona_name:
+            display_entries = [e for e in app.disc_entries
+                              if e.get("role") == persona_name or e.get("role") == "User"]
+```
+
+When the user clicks "Focus on Tier 3 Worker A" in the MMA dashboard, the Discussion Hub filters to only show entries whose `role` matches the focused worker's persona name plus User entries. This is a *read-only* filter — the underlying `disc_entries` is unchanged. The `app._render_message_panel` (or whoever sent the entries) is unaffected.
+
+---
+
+## Persistence
+
+### `app._flush_to_project` (called from B4 Save, and from `_switch_discussion`)
+
+`gui_2.py:1046-1047` and `app_controller.py:2558`:
+
+```python
+app._flush_to_project()       # serializes self.project to <project_root>/<project_name>.toml
+app._flush_to_config()         # serializes self.config to <user_config>/config.toml
+app.save_config()              # write config.toml to disk
+```
+
+`_flush_to_project` calls `project_manager.save_project(self.project, self.active_project_path)`, which serializes the full project dict (including all discussions) to the project TOML.
+
+### `_flush_disc_entries_to_project` (called from `_switch_discussion` and `_branch_discussion`)
+
+`app_controller.py:3225-3240`:
+
+```python
+def _flush_disc_entries_to_project(self) -> None:
+    history_strings = [project_manager.entry_to_str(e) for e in self.disc_entries]
+    if self.active_track and self._track_discussion_active:
+        project_manager.save_track_history(self.active_track.id, history_strings, self.active_project_root)
+        return
+    disc_sec = self.project.setdefault("discussion", {})
+    discussions = disc_sec.setdefault("discussions", {})
+    disc_data = discussions.setdefault(self.active_discussion, project_manager.default_discussion())
+    disc_data["history"] = history_strings
+    disc_data["last_updated"] = project_manager.now_ts()
+    disc_data["context_snapshot"] = [f.to_dict() if hasattr(f, "to_dict") else {"path": str(f)} for f in self.context_files]
+    disc_data["sent_markdown"] = getattr(self, "discussion_sent_markdown", "")
+    disc_data["sent_system_prompt"] = getattr(self, "discussion_sent_system_prompt", "")
+```
+
+**Two paths:**
+- If a track discussion is active (`self.active_track and self._track_discussion_active`): persist to `conductor/tracks/<id>/track_history` via `save_track_history`.
+- Otherwise: persist to the project's `discussion.discussions[<active>]` dict.
+
+`entry_to_str(e)` converts an entry dict to a `Role: content` string for the legacy `history` field. `parse_history_entries` (in `models.py:196`) reverses the conversion when loading.
+
+**The `context_snapshot`** is the FileItem list at send time. Restoring a discussion restores the file list (per `_switch_discussion:3218-3222`). This is *the* mechanism for "I sent this discussion with these files in context; if I switch away and back, the files come back."
+
+### When is the save triggered?
+
+- **Explicit:** B4 `Save` button.
+- **Implicit (and risky):** `_switch_discussion` and `_branch_discussion` both flush *before* switching. **But** the per-entry edit operations (A1-A7) do *not* flush on their own. The user is expected to either Save explicitly or rely on the next `_switch_discussion` / `_branch_discussion` to flush.
+
+This is a known design tension. See the "Known Limitations" section below.
+
+---
+
+## Threading & Locking
+
+`self._disc_entries_lock: threading.Lock` is a `threading.Lock` owned by `app_controller`. It is acquired in:
+
+- `_switch_discussion` (`app_controller.py:3214-3215`) — to atomically replace `disc_entries[:]`
+- `app._process_pending_gui_tasks` (called from render loop) — to read entries safely while a background thread appends an AI response
+- `truncate_entries` (via the panel-level `Truncate` button) — to atomically replace `disc_entries` with the truncated list
+- `gui_2.py:4060, 4223-4224` — the AI response callback appends a new entry under the lock
+- `gui_2.py:4359` (in `render_discussion_selector` when track-discussion is toggled) — flushes under the lock
+
+**Invariant:** the lock is *never* held across a render call. The lock is acquired, `disc_entries[:] = ...` is done, the lock is released. The ImGui renderer reads `disc_entries` lock-free; it sees either the old list or the new list but never a half-updated one.
+
+**Cross-thread append pattern** (the AI response callback at `gui_2.py:4060`):
+
+```python
+with app._disc_entries_lock:
+    app.disc_entries.append({"role": "user", "content": prompt, "collapsed": False, "ts": project_manager.now_ts()})
+```
+
+The background thread (e.g. `_bg_task`) appends; the render thread reads. The lock is the *only* synchronization primitive — there is no event loop, no message queue, no signal. The render thread polls at frame rate (60 FPS nominal); if the background thread appends between frames, the next frame sees the new entry.
+
+---
+
+## Undo/Redo Integration
+
+The discussion system is integrated with `HistoryManager` + `UISnapshot` for full undo/redo. See `guide_state_lifecycle.md` for the full architecture. The relevant details for discussions:
+
+- `UISnapshot.disc_entries: list[dict]` (`src/history.py:19`) captures the full entry list via `copy.deepcopy(self.disc_entries)` (`gui_2.py:748`).
+- The change-detection logic at `gui_2.py:1160, 1166-1167` checks if `disc_entries` length or last-entry content changed; if so, a new snapshot is pushed to the undo stack.
+- `Ctrl+Z` restores the previous `disc_entries` via `gui_2.py:754 _apply_snapshot`.
+
+**Per-edit granularity.** A snapshot is pushed *per render frame* that detects a change. The 100-snapshot cap means you can rewind up to ~100 edits. For a 5-second window of rapid typing, that's a lot. For long sessions with infrequent edits, the history can span hours.
+
+---
+
+## Reset (Destroying the Discussion)
+
+`app_controller._handle_reset_session` (`app_controller.py:3286-3356`) is the **nuclear** reset:
+
+- `self.disc_entries.clear()` — empties the current take
+- `for d_name in discussions: discussions[d_name]["history"] = []` — empties ALL takes and ALL discussions
+- Resets `discussion_sent_markdown` and `discussion_sent_system_prompt` to `""`
+- Resets the entire project dict to `default_project(...)` — this is a *new* empty project, not the user's saved one
+
+**The reset is intentionally aggressive.** The 2026-06-08 `_handle_reset_session` regression (documented in the comments at `app_controller.py:3307-3312`) was caused by an early version that *also* cleared `self.active_project_path`, leading to an infinite re-switch loop. The fix is to leave `active_project_path` alone.
+
+**What reset does NOT touch:**
+- `self.project` is replaced, but the user's *saved* project TOML on disk is untouched. Switching projects after reset reloads from disk.
+- `app.history` (the `HistoryManager`) is not cleared. The undo stack survives a reset — Ctrl+Z after a reset can restore the pre-reset discussion state. This may be a bug or a feature depending on user expectation.
+- `self.active_project_path` is preserved.
+
+---
+
+## Hook API Surface
+
+The discussion system is exposed to the Hook API via two endpoints (per `guide_tools.md`):
+
+| Method | Endpoint | Behavior |
+|---|---|---|
+| `GET /api/session` | Direct read | `{"session": {"entries": [...]}}` from `app.disc_entries` |
+| `POST /api/session` | `{"session": {"entries": [...]}}` | `{"status": "updated"}` — sets `app.disc_entries` |
+
+The POST endpoint allows external automation to *replace* the entire discussion. Per-entry inserts/deletes are not currently exposed via the Hook API (only full-replacement). This is a known gap.
+
+`api_hook_client.py` exposes `get_session()` and `set_session(entries)` as the Python-side wrappers.
+
+---
+
+## Tests
+
+- `tests/test_discussion_takes.py` — `TestDiscussionTakes` covers `branch_discussion` (creates a new Take) and `promote_take` (renames a Take to top-level).
+- `tests/test_gui_discussion_tabs.py` — `test_discussion_tabs_rendered` covers the discussion selector and Take tabs.
+- `tests/test_discussion_takes_gui.py` — `test_render_discussion_tabs` and `test_switching_discussion_via_tabs` cover the GUI flow.
+- `tests/test_history.py` — `test_undo_redo`, `test_jump_to_undo`, `test_max_capacity`, `test_redo_cleared_on_push`, `test_push_state` cover the undo/redo integration.
+- `tests/test_history_manager.py` — `TestHistoryManager` covers `snapshot_roundtrip`, `push_and_undo`, `push_clears_redo_stack`, `undo_and_redo`, `undo_no_history_returns_none`, `redo_no_history_returns_none`, `get_history_returns_descriptions`, `jump_to_undo`.
+- `tests/test_session_logger_reset.py` — `test_reset_session` covers the reset path.
+- `tests/test_gui_fast_render.py` — `test_render_discussion_panel_fast` covers the render path.
+- `tests/test_gui_phase4.py` — `test_track_discussion_toggle` covers the track-discussion toggle.
+- `tests/test_gui_symbol_navigation.py` — `test_render_discussion_panel_symbol_lookup` covers the `@Symbol` lookup integration.
+
+---
+
+## Known Limitations
+
+1. **Per-edit save is implicit.** The per-entry edit operations (A1-A7) do not flush to TOML on every edit. The save happens on the next `_switch_discussion`, `_branch_discussion`, or explicit B4 Save. A crash between edit and save loses the edit. Fix: hook the change-detection logic in `gui_2.py:1160, 1166-1167` to also call `_flush_disc_entries_to_project` after a debounce.
+2. **Provider-side history diverges from `disc_entries`.** When the user edits an entry's `content` via A1, the *displayed* text is corrected but the *provider-side* `ai_client._anthropic_history` (and siblings) still contains the original. The next LLM call may replay the original tool results. This is Pitfall #4 in `conductor/tracks/nagent_review_20260608/report.md` and the corresponding Decision candidate #3 (Stateless LLMClient).
+3. **Hook API is full-replacement only.** No per-entry insert/delete via the API. The user could `POST /api/session` with a new list, but partial edits require the full list.
+4. **Truncate is destructive.** The `Truncate` button (B10) is not undoable as a single operation — it's a list replacement, so the undo stack pushes the new (truncated) list, not the pre-truncate list. Actually, it *is* pushed (per the change-detection logic), so Ctrl+Z restores the pre-truncate list. Confirmed working in `tests/test_history.py`.

+> **Critical (bcdc26d0):** The current code includes the `hasattr(self.controller, name)` guard in `__getattr__`. The previous version (without this guard) was a silent-None bug: any uninitialized `ui_` attribute on the App would have called `getattr(self.controller, name)` → raised `AttributeError` from Python → the ImGui code would catch that and return `None` → the GUI would render blanks silently instead of crashing. The `hasattr` guard makes the `AttributeError` propagate correctly so the bug surfaces during development. The fix is in `src/gui_2.py:688-693`.
+
 **Why this matters:**
 - The `Controller` is the single source of truth for settable state (e.g. `ui_ai_input`, `ui_separate_tier1`, `show_windows`, `temperature`).
 - The `App` is a thin view layer that delegates reads (`__getattr__`) and writes (`__setattr__`) to the Controller.

This bit the project in 2026-06-05 during a cleanup commit: `_capture_workspace_profile` was being parsed as nested inside `_apply_snapshot` due to a 1-space indentation drift, breaking 3 live_gui tests (test_auto_switch_sim, test_workspace_profiles_restoration, test_undo_redo_lifecycle).

+### Startup Architecture (Lazy Imports, Profiler, Refresh Rate)
 
+The 2026-06-06 `startup_speedup_20260606` track restructured `gui_2.py` for ~2400ms faster startup. The key components:
 
+**`_LazyModule` proxies** (`np`, `filedialog`, `Tk`, `win32gui`, `win32con`): Defer `import numpy`, `import tkinter.filedialog`, `import tkinter`, `import win32gui`, `import win32con` until first attribute access. The first `gui_2` import drops from ~1770ms to ~341ms.
+
+**`_FiledialogStub`**: No-op fallback for tkinter-less environments (e.g., headless CI). Sets `available = False` so the GUI can detect and skip file dialogs gracefully.
+
+**`startup_profiler` + `render_warmup_status_indicator(app)`**: `AppController(defer_warmup=True)` defers heavy SDK warmup (google.genai, anthropic, openai, fastapi) to a background thread. `startup_profiler.phase(name)` wraps each init phase and reports per-phase duration. `render_warmup_status_indicator` is called per-frame during the warmup window to show a progress indicator in the UI. The warmup completes asynchronously; `_on_warmup_complete_callback` is invoked when done. See [guide_architecture.md](guide_architecture.md#warmup-architecture) for the full mechanism.
+
+**Native refresh rate detection** (`_detect_refresh_rate_win32`): The old implementation used a PowerShell/WMI subprocess (~350ms blocking). The new implementation uses `ctypes.windll.user32.EnumDisplaySettingsW` directly (~0.3ms, 1000x faster). Used by the ImGui IO setup to set the display refresh rate.
+
+**`immapp.run` error handling**: `immapp.run` is wrapped in try/except catching `RuntimeError` from native ImGui bundle assertions. On native crash, `_gui_degraded_reason` and `_last_imgui_assert` are set on the controller, and the GUI enters a degraded mode (rendering a static error panel instead of the live UI). This prevents the Python process from being killed by an uncatchable Windows access violation (`0xc0000005`).
