fix(test): correct filename typo manualslop.toml -> manual_slop.toml in project switch

Tier 2's project-switch fix (commit 455c17ff) was correct but used
'manualslop.toml' (no underscore) instead of 'manual_slop.toml'. The
if Path(workspace_toml).exists() check was False, so the switch was
silently skipped — the subprocess stayed on whatever stale project a
prior test left, and the RAG engine used the wrong base_dir.

Fixing the filename makes the project switch actually fire. The test
now passes 4/4 runs in isolation (6-7s each). The RAG context block
appears in the discussion history as expected.

+### 8.5 The Python Type Promotion Mandate (added 2026-06-25)
+
+**C11/Odin/Jai semantics in a Python runtime.** This codebase is written in Python because of practical constraints (time, dependencies, LLM codegen ability), but the convention is to make Python behave as close to a statically-typed value-typed language as the runtime allows. **LLMs default to opaque types (`dict[str, Any]`, `Any`, `Optional[T]`, `hasattr()` polymorphism) because that's what idiomatic Python training data looks like. That defaults to mediocrity; this rule overrides it.**
+
+**The 7 banned patterns** (any of these in a non-boundary file is an anti-pattern; the audit scripts flag them):
+
+| Banned | Why | Use instead |
+|---|---|---|
+| `dict[str, Any]` (parameter or return) | Open-ended; hides the schema; invites `.get('any_key', default)` defensive checks | A typed dataclass (`@dataclass(frozen=True, slots=True)`) with explicit fields |
+| `Any` (parameter, return, or field) | Same problem; LLMs use it to avoid thinking about types | A specific typed dataclass or one of the concrete types in `src/type_aliases.py` |
+| `Optional[T]` (return) | `None` requires a runtime check; propagates through call sites | `Result[T]` (with errors as data) or a `NIL_T` sentinel (zero-initialized frozen dataclass) |
+| `hasattr(x, 'field')` for entity type dispatch | Runtime type check; defeats the type system | `isinstance(x, TypedDataclass)` against a typed Union, or refactor so the function takes a typed parameter (no dispatch needed) |
+| `getattr(x, 'field', default)` on a known-typed value | Same; the type system should guarantee the field exists | `x.field` direct access; if the field is nullable, the dataclass has `Optional[T]` as a field type (and the value is checked at construction, not at every read) |
+| `.get('field', default)` on a `dict[str, Any]` for a known field | Runtime type-dispatch branch | Direct attribute access on the typed dataclass |
+| `if 'field' in dict` checks | Same | Direct attribute access (the dataclass has a default value) |
+
+**The one exception (the boundary layer):** at the literal wire boundary (TOML parsing, JSON parsing, vendor SDK response parsing), the data is open-ended for the 100ns between parsing and `from_dict()` conversion. At that boundary:
+
+- The function that calls `tomllib.load()` or `json.loads()` may return `Metadata` (the typed fat struct — see §8.6).
+- Every consumer of that function IMMEDIATELY calls `SomeTypedDataclass.from_dict(metadata)` and uses the typed result.
+- The boundary is 2-3 functions per file (one per wire entry point).
+
+**No other code uses `Metadata` or `dict[str, Any]` or `Any`.** This is enforced by `scripts/audit_weak_types.py --strict` (existing) + the boundary-layer audit (planned in `conductor/tracks/cruft_elimination_20260627/spec.md`).
+
+### 8.6 The Boundary Layer (the wire schema)
+
+The codebase has ONE typed fat struct at the boundary: `Metadata` in `src/type_aliases.py`. It is `@dataclass(frozen=True, slots=True)` with explicit fields covering the TOML/JSON wire schema (paths, project, discussion, role, content, ts, source_tier, model, depends_on, document, script, args, etc.). It is used in exactly 2 places:
+1. TOML loaders (`tomllib.load()` → `Metadata.from_dict(...)` → typed config)
+2. JSON wire parsers (`json.loads()` → `Metadata.from_dict(...)` → typed request/response)
+
+After the boundary, every value is a typed componentized dataclass (`CommsLogEntry`, `HistoryMessage`, `FileItem`, `Ticket`, `ToolCall`, `ChatMessage`, `UsageStats`, `RAGChunk`, `SessionInsights`, `DiscussionSettings`, `CustomSlice`, `MMAUsageStats`, `ProviderPayload`, `UIPanelConfig`, `PathInfo`, `ToolDefinition`).
+
+**The componentized dataclasses exist for specific paths.** A function that handles ONE entity type takes that type's dataclass directly. A function that genuinely handles multiple entity types in ONE generalized path takes a Union: `def handle(x: CommsLogEntry | FileItem | HistoryMessage) -> None:` with `isinstance(x, CommsLogEntry)` dispatch. **NOT** `def handle(x: Metadata) -> None:` with `hasattr(x, 'tool_calls')` dispatch.
+
+**Why this matters:** the dispatcher functions in `src/app_controller.py` and `src/gui_2.py` had `if hasattr(...)` chains that contributed to the 4.01e+22 effective-codepaths metric (`Σ 2^branches(f)`). After this rule is enforced, those functions take typed parameters, the `hasattr` chains collapse to single `isinstance` checks or are eliminated entirely, and the metric drops by 4+ orders of magnitude.
+
+### 8.7 The "C11/Odin/Jai in Python" framing
+
+| C11/Odin/Jai concept | Python equivalent |
+|---|---|
+| Value type (`struct Foo { int x; string y; }`) | `@dataclass(frozen=True, slots=True) class Foo: x: int = 0; y: str = ""` |
+| Static type (`int`, `string`) | Type hint + mypy in CI |
+| No null | `Result[T]` (errors as data) or `NIL_T` sentinel (zero-initialized frozen dataclass) |
+| Direct field access (`foo.x`) | `foo.x` direct attribute access (not `foo.get('x', default)`) |
+| No dynamic dispatch (`if hasfield`) | Compile-time-typed function params (no `hasattr()` runtime dispatch) |
+| Explicit conversion at boundary (`parse_wire(bytes) -> Foo`) | `Foo.from_dict(wire_dict)` at the wire entry; internal code never sees the wire format |
+
+**If you find yourself writing `dict[str, Any]`, `Any`, `Optional[T]`, `hasattr()`, or `.get()` for type dispatch, stop and ask: "what typed dataclass should this be?"** The answer is usually in `src/type_aliases.py` (12 existing) or you need to add one.
+
 - **Latency and throughput are only the same thing in a sequential system.** For every performance requirement, identify which one it actually is before designing for it.
 - The compiler and language are tools, not magic: memory layout, access order, and the choice of what work to do at all are your job, not theirs — and they are roughly 90% of the problem. Know what the compiler can reasonably do with what you wrote, and don't delegate what it can't.

+## The OBLITERATE Principle (Result Migration Anti-Pattern)
+
+**Added 2026-06-27** (from `result_migration_cruft_removal_20260620`).
+
+When a function is migrated from `Optional[T]` / `raise` to `Result[T]`:
+
+- **NO pass-throughs.** Do NOT keep a legacy wrapper like `def _x(): return _x_result(...).data`. The wrapper is dead code the moment the migration lands.
+- **NO backward compat.** Do NOT keep the old return type alongside the new one. Pick one (the new `Result[T]`), and delete the other.
+- **In-site callers rewritten in the same atomic commit.** Every caller of the migrated function must be updated to use `result.ok` / `result.errors` / `result.data` directly. No deprecation period. No "we'll fix it later."
+- **The dead code dies.** Legacy `def _x_result_to_x(...)` shims, `_x_result()` passthrough helpers, and conditional return-type guards must be deleted in the same commit that introduces `Result[T]`. Leaving them creates two equivalent APIs that future agents must disambiguate.
+
+### The wrong pattern (pass-through that should be obliterated)
+
+```python
+# BEFORE (the legacy):
+def do_thing() -> Optional[str]:
+    result = do_thing_result()
+    if not result.ok: return None
+    return result.data
+
+# AFTER (the new):
+def do_thing_result() -> Result[str]:
+    ...
+```
+
+The `do_thing` function must be **deleted**, not kept as a wrapper. Keep only one entry point: `do_thing_result()`.
+
+### The right pattern (single canonical entry point)
+
+```python
+# After OBLITERATE: only do_thing_result exists
+def do_thing_result() -> Result[str]:
+    ...
+```
+
+Callers are rewritten:
+```python
+# BEFORE:
+result = do_thing()
+if result is None: handle_failure()
+
+# AFTER:
+result = do_thing_result()
+if not result.ok: handle_failure(result.errors)
+```
+
+### Why this rule
+
+The `result_migration_cruft_removal_20260620` track ended with 9 legacy wrappers across 4 files (`mcp_client`, `ai_client`, `rag_engine`, `gui_2`). The wrappers were dead code that added visual noise, broke `mypy --strict`, and required every new caller to decide which path to use. Removing them required `Phase 9: LEGACY_WRAPPER_OBLITERATION` as an explicit step — that step should never have been necessary. **Don't ship pass-through wrappers in the first place.**

+- `scripts/audit_imports.py --strict` — flags local imports (§17.9a) + `_PREFIX` aliasing (§17.9b) in all `src/*.py`; reads `scripts/audit_imports_whitelist.toml` for warmed-imports/hot-reload exceptions (use `--no-whitelist` to audit all files; `--show-whitelist` to inspect current whitelist)
+- The new `boundary_layer` audit (planned in `conductor/tracks/cruft_elimination_20260627/spec.md`) — documents every `Metadata` usage with justification
+- Pre-commit: every commit MUST pass all four audits above
+
+### 17.9 Banned: Local imports + aliasing-for-naming-convenience + repeated `from_dict()` (Added 2026-06-27)
+
+**LLMs default to local imports with `as _PREFIX` aliasing.** This is the "I don't want to repeat the long name" pattern. It's banned. Local imports add overhead; aliasing hides intent; repeated `.from_dict()` calls in the same expression are wasteful.
+
+**17.9a — Banned: Local imports inside functions**
+
+```python
+# BANNED:
+def calculate_total(app):
+    from src.type_aliases import MMAUsageStats as _MMA   # ← local import; defeats static analysis
+    return sum(_MMA.from_dict(u).model for u in app.mma_tier_usage.values())
+
+# CORRECT:
+# Add the import at the top of the module:
+#   from src.type_aliases import MMAUsageStats
+
+def calculate_total(app):
+    return sum(u.model for u in app.mma_tier_usage.values())
+```
+
+**Why:** local imports:
+- Add per-call import overhead (cached after first call, but still pollutes the namespace).
+- Defeat static analysis (ruff/mypy can't see what's imported where).
+- Hide dependencies (a reader has to scroll to find what's actually used).
+- Encourage the aliasing anti-pattern (see 17.9b).
+
+**Three exceptions** (in order of preference; all require explicit justification):
+
+1. **`try/except ImportError:` blocks for optional dependencies** — the canonical "optional dependency" pattern. Detected structurally: the import must be a direct child of a `Try` whose handlers all catch `ImportError`.
+2. **Vendor SDK warmup imports** — heavyweight SDKs (imgui_bundle, google.genai, chromadb) deferred to first use so the GUI can render immediately. Detected by per-file whitelist entry in `scripts/audit_imports_whitelist.toml` with a `reason` field documenting the warmup pattern.
+3. **Hot-reload re-imports** — module references swapped by `HotReloader` at runtime; the late import is the hot-reload boundary. Detected by per-file whitelist entry with a `reason` field documenting the hot-reload pattern.
+
+**The whitelist mechanism** (per-file entries with rationale): `scripts/audit_imports_whitelist.toml` lists files whose local imports are intentional. The audit script reads the whitelist at startup; whitelisted files get a single `WHITELISTED` annotation per file (so the user knows the script saw the violations but is not flagging them) instead of N strict `LOCAL_IMPORT` findings. Use `--no-whitelist` to audit ALL files; `--show-whitelist` to inspect the current whitelist.
+
+**To add a file to the whitelist:** append a `[whitelist."<relative_path>"]` entry with a `reason` string. The reason is mandatory and must explain WHY the local imports are intentional (warmed SDK, hot-reload, circular-dep avoidance, etc.). Per-line whitelist entries are not supported because the patterns are too dense (e.g., gui_2.py has 68 LOCAL_IMPORT sites — all hot-reload).
+
+**17.9b — Banned: `import X as _X` aliasing-for-naming-convenience**
+
+```python
+# BANNED:
+from src.type_aliases import MMAUsageStats as _MMA
+from src.openai_schemas import ToolCall as _TC
+from src.models import FileItem as _FI
+
+# CORRECT:
+from src.type_aliases import MMAUsageStats
+from src.openai_schemas import ToolCall
+from src.models import FileItem
+```
+
+**Why:** `_PREFIX` aliasing is "I don't want to repeat the long name, so I'll shorten it." But the long name IS the documentation — `MMAUsageStats` tells you what it is; `_MMA` is opaque. The "long name" is rarely actually long enough to justify aliasing. If you find yourself aliasing to shorten, the real problem is the function is too long — extract.
+
+**17.9c — Banned: Repeated `.from_dict()` calls in the same expression**
+
+```python
+# BANNED:
+from src.type_aliases import MMAUsageStats as _MMA
+total_cost = sum(cost_tracker.estimate_cost(
+    _MMA.from_dict(u).model or 'unknown',
+    _MMA.from_dict(u).input,
+    _MMA.from_dict(u).output,
+) for u in app.mma_tier_usage.values())
+
+# CORRECT:
+total_cost = sum(cost_tracker.estimate_cost(
+    stats.model or 'unknown',
+    stats.input,
+    stats.output,
+) for stats in (
+    MMAUsageStats.from_dict(u) if isinstance(u, dict) else u
+    for u in app.mma_tier_usage.values()
+))
+```
+
+**Why:** repeated `.from_dict()` calls:
+- Waste work (parse the same dict multiple times).
+- Indicate a broken design (the variable's type isn't right).
+- Should be cached in a local variable OR the type should be promoted at the boundary so `from_dict()` isn't called at the consumer site at all.
+
+The CORRECT pattern (preferred): promote the type at the boundary. After `cruft_elimination_20260627`, `app.mma_tier_usage` is typed `dict[str, MMAUsageStats]` (the boundary does `from_dict()` ONCE). The consumer iterates `stats.model`, `stats.input`, `stats.output` directly. No `from_dict()` at the consumer site.

 ## The 5 Decision Patterns
 
-### 1. Use `Metadata` for any dict-shaped record
+### 1. Use `Metadata` ONLY at the wire boundary (TOML/JSON parse)
+
+**UPDATED 2026-06-25 (the C11/Odin/Jai-in-Python mandate).** `Metadata` is the typed fat struct at the wire boundary. It is `@dataclass(frozen=True, slots=True)` with explicit fields covering the TOML/JSON wire schema (paths, project, discussion, role, content, ts, source_tier, model, depends_on, document, script, args, etc.).
 
 ```python
-def parse_metadata(raw: str) -> Metadata:
- return json.loads(raw)
+# CORRECT — at the literal wire boundary:
+def _parse_toml_config(raw: str) -> Metadata:
+ return Metadata.from_dict(tomllib.loads(raw))
 
-def save_metadata(name: str, data: Metadata) -> None:
- ...
+# CORRECT — consumer at the boundary, converts immediately:
+def _load_project_context(raw_toml: Metadata) -> ProjectContext:
+ return ProjectContext.from_dict(raw_toml)
+
+# WRONG — using Metadata as a lazy-typing escape hatch:
+def process_event(self, event: Metadata) -> None:
+ if hasattr(event, 'tool_calls'):
+  ...   # ← BAD: this is the laziest possible typing
 ```
 
-The alias is `dict[str, Any]` at runtime; the name documents the semantic role.
+`Metadata` is **NOT** `TypeAlias = dict[str, Any]`. It is a typed fat struct. The boundary is 2-3 functions per file. Every consumer IMMEDIATELY converts to a componentized dataclass via `from_dict()`.
+
+**Anti-pattern (banned):** `Metadata: TypeAlias = dict[str, Any]` (the lazy-typing escape hatch). LLMs default to this because it's idiomatic Python. This codebase does NOT do idiomatic Python. See `data_oriented_design.md` §8.5.

-The underlying type is still `dict[str, Any]`; the alias name is the documentation.
+**Updated 2026-06-27** — `Metadata` is itself a `@dataclass(frozen=True, slots=True)` with 36 explicit fields covering the wire schema. It is NOT a `TypeAlias = dict[str, Any]` anymore. The aliases below (e.g., `CommsLogEntry`, `HistoryMessage`) point to their own per-aggregate dataclasses, not to `Metadata`. The original "names for shapes" pattern has been promoted to the structural level (per §2.5).

Do **NOT** share one mega-dataclass across multiple concepts.
 
 **Why:** the per-aggregate dataclass is the "names for shapes" pattern extended to the structural level. Each concept gets its own type, its own fields, its own `to_dict()` / `from_dict()` round-trip. Consumers use direct field access (`entry.ts`, `t.depends_on`, `chunk.document`) which compiles to a single C-level field read with 0 branches.
 
-**When NOT to promote:** when the shape is genuinely unknown at type level (TOML project config, generic JSON parsing at a wire boundary, polymorphic log dumping). These are **collapsed codepaths** and they keep `Metadata: TypeAlias = dict[str, Any]` as the catch-all.
+**When NOT to promote:** when the shape is genuinely unknown at type level and the fields are heterogeneous (e.g., log entries from 5 different vendors with mutually-exclusive keys).

Do NOT use `dict[str, Any]` directly anywhere; `Metadata` is the typed replacement.

+## Core Value (Added 2026-06-25)
+
+**C11/Odin/Jai semantics in a Python runtime.** This codebase is written in Python because of practical constraints (time, dependencies, LLM codegen ability), but the convention is to make Python behave as close to a statically-typed value-typed language as the runtime allows.
+
+**LLMs default to opaque types (`dict[str, Any]`, `Any`, `Optional[T]`, `hasattr()` polymorphism) because that's what idiomatic Python training data looks like. That defaults to mediocrity. This rule overrides it.**
+
+The canonical mandate is in `conductor/code_styleguides/data_oriented_design.md` §8.5 (The Python Type Promotion Mandate). The banned patterns are in `conductor/code_styleguides/python.md` §17 (LLM Default Anti-Patterns). The enforcement audits are:
+- `scripts/audit_weak_types.py --strict`
+- `scripts/audit_optional_in_3_files.py --strict` (extended to all `src/*.py`)
+- The boundary-layer audit (planned in `conductor/tracks/cruft_elimination_20260627/spec.md`)
+
+**Every section of this document, every styleguide in `conductor/code_styleguides/`, and every deep-dive guide in `docs/guide_*.md` MUST be read through the lens of this Core Value.** If a section suggests `dict[str, Any]`, `Any`, `Optional[T]`, or `hasattr()` for entity dispatch in non-boundary code, that's an anti-pattern; flag it and ask.
+
 ## Documentation Style
 
 - **Strict & In-Depth:** Documentation must follow an old-school, highly detailed technical breakdown style (similar to VEFontCache-Odin). Focus on architectural design, state management, algorithmic details, and structural formats rather than just surface-level usage.

 5. `conductor/tracks/tier2_leak_prevention_20260620/spec.md` — the prior leak incident + 3-layer defense (DO NOT REPEAT IT)
-6. `conductor/code_styleguides/data_oriented_design.md` — canonical DOD reference

+## MANDATORY: The Banned Patterns (DO NOT INTRODUCE — added 2026-06-27)
+
+From `conductor/code_styleguides/python.md` §17. The Tier 2 prompt and all Tier 3 worker tasks MUST NOT introduce these patterns in non-boundary code:
+
+- **`dict[str, Any]` parameter/return/field types** — use typed `@dataclass(frozen=True, slots=True)` with explicit fields
+- **`Any` types** — use the concrete typed dataclass
+- **`Optional[T]` returns** — use `Result[T]` + `NIL_T` sentinels (per `error_handling.md`)
+- **`hasattr()` for entity type dispatch** — use typed Union or per-entity function; the type system guarantees the entity type
+- **Local imports inside functions** — top-of-module imports only (per `python.md` §3)
+- **`import X as _PREFIX` aliasing** — use the original name; the long name IS the documentation
+- **Repeated `.from_dict()` calls in the same expression** — cache the result or promote the type at the boundary
+- **`.get('field', default)` on a `dict[str, Any]` for a known field** — direct attribute access on the typed dataclass
+- **`if 'field' in dict` checks** — direct attribute access
+
+**The ONE exception:** the literal wire boundary (TOML/JSON parse functions) may use `dict[str, Any]` + `Metadata.from_dict(...)`. This is the only place the banned patterns are allowed.
+
+If a track proposes lifting entities into `dict[str, Any]` or `Any`, REJECT and rewrite.

You can grab artifacts, code, or files from old commits via `git show <sha>:<path> > <new-path>` or `git checkout <sha> -- <path>` (note: `git checkout <sha>` for FILE extraction is allowed; `git checkout <branch>` to switch is BANNED). But you CANNOT reset the branch HEAD to an old commit and pretend the wrong work never happened. The wrong work is part of history now; the fix is a follow-up commit that supersedes it. **NEVER use `git revert`, `git reset --hard`, or `git reset --soft`** to "undo" a bad commit — always go FORWARD with a corrective commit.
+- `git stash*` (any form: `git stash`, `git stash pop`, `git stash apply`, `git stash drop`, `git stash clear`) - per AGENTS.md hard ban (added 2026-06-27); stashing throws away the user's in-progress edits silently. If you think you need a stash, you don't - use a NEW BRANCH or a WORKTREE instead. The 2026-06-27 `cruft_elimination_20260627` track was corrupted by Tier 2 using `git stash` and losing the user's in-progress files.
 - File access outside the Tier 2 clone - the OS blocks it. **NEVER USE APPDATA** for any read, write, or shell command; the `*AppData\\*` bash deny rule will halt the run if you try.

+### THE TIMELINE-IS-IMMUTABLE PRINCIPLE (added 2026-06-27, after the cruft_elimination corruption)
+
+When you (the agent) fuck up — make a wrong commit, break a file, take a bad path — your first instinct will be to "undo" the mistake with `git revert`, `git reset`, or `git stash`. **THIS INSTINCT IS WRONG.** The user explicitly stated: "if an agent fucks up, their tendency to want to 'revert' is not correct and instead they must live with the timeline and just do corrections with a new commit."
+
+**The rule:**
+- The git history is IMMUTABLE on this branch. Every commit you've made is part of the record.
+- "Undoing" via `git revert` / `git reset` / `git stash` makes the user's review harder, not easier (the user has to read the diff between the bad and the "fix" to understand what went wrong).
+- "Fixing forward" via a new commit makes the user's review EASIER: they can see exactly what changed between the bad commit and the fix.
+
+**Correct pattern when you fuck up:**
+1. Pause. Read the actual file. Confirm the state.
+2. Write a NEW commit that fixes the problem. The commit message should briefly say what was wrong and what you fixed.
+3. If the bad commit introduced data corruption that the user will see, the user can `git revert` it during their review — that's the user's choice, not yours.
+4. If you need to recover an old version of a file (because the bad commit destroyed it), use `git show <good-sha>:<path> > <path>` to extract it. The bad commit is still in history; you're just reading from history to recover.
+
+**Wrong pattern (which you must NOT do):**
+- `git revert <sha>` to undo a commit
+- `git reset --hard <sha>` to throw away a bad commit
+- `git stash` to "save" uncommitted work (it just disappears when you lose the branch)
+- `git checkout <old-sha> -- .` to "go back to when things were good" (and then commit on top)
+
+These are all attempts to rewrite history. They are BANNED. The right answer is always a forward commit.
+
+**Concrete example:** if you realize commit N introduced a bug, write commit N+1 that fixes the bug. The user can see both commits in the diff and understand the full story. The user's CI / reviews / git log will all show both commits, which is what they want.

 - **Test runner:** ALWAYS use `uv run python scripts/run_tests_batched.py` for test runs. NEVER call `uv run pytest` directly. The batched runner provides tier-based filtering, parallelization (xdist), and a summary table. Direct pytest is slow and bypasses the tiering that the live_gui tests depend on.
+- **NEVER filter test output** (added 2026-06-27 per user directive). Do NOT pipe test output through `Select-Object`, `| Select -First N`, `| Select -Last N`, `head`, `tail`, or any truncation filter. If you need to see more output later, you'll have to re-run the entire test — which wastes time and context. Instead, ALWAYS redirect to a log file: `uv run python scripts/run_tests_batched.py > tests/artifacts/tier2_state/<track>/test_run_<phase>_<task>.log 2>&1`. Then read the log file with `manual-slop_read_file` or `grep` to find the relevant sections. The log file is your full record; you can search it without re-running.
+- **Prefer targeted tier runs** (added 2026-06-27 per user directive). Do NOT run the full 11-tier batch for every verification. Run only the tiers relevant to the current task (e.g., `uv run python scripts/run_tests_batched.py --tier tier3` or `--filter test_<specific_file>`). The full batch is for the USER to run after merge review, not for Tier 2's per-task verification. Running the full batch every time wastes 20+ minutes and the output is too large to be useful in context.
 - **Default branch:** this repo uses `master` (not `main`). Always use `origin/master` in `git fetch` and as the base for new branches. Do not assume `main` exists.

 - **Throw-away scripts:** write them to `scripts/tier2/artifacts/<track-name>/`, NOT the base `scripts/tier2/` directory. The base directory is reserved for production code that ships with the sandbox (failcount.py, run_track.py, write_report.py, the .ps1 launchers). Throw-away scripts are kept for archival but live in a track-specific subdir so they don't pollute the base.

+# SPEC CORRECTION: Phase 2 — ProjectContext Field Shape
+
+**Track:** `cruft_elimination_20260627`
+**Phase:** 2 (Fix `flat_config` to return typed `ProjectContext`)
+**Date:** 2026-06-27
+**Author:** Tier 1 (post-mortem of VC8 mismatch)
+**Status:** Awaiting Tier 2 resumption
+
+---
+
+## TL;DR
+
+The spec for Phase 2 says: "Add `ProjectContext` to `src/models.py` with all fields observed in `src/project_manager.py:flat_config`." This is underspecified. The actual `flat_config` returns a NESTED dict structure with 6 top-level fields, each with sub-fields. The spec doesn't enumerate which fields belong to `ProjectContext` (a flat dict) vs which are sub-objects.
+
+This correction specifies the exact schema. Tier 2 can resume Phase 2 directly.
+
+---
+
+## Actual `flat_config` return shape (measured from `src/project_manager.py:268`)
+
+```python
+def flat_config(proj: Metadata, disc_name: Optional[str] = None, track_id: Optional[str] = None) -> Metadata:
+    ...
+    return {
+        "project":         proj.get("project", {}),
+        "output":          proj.get("output", {}),
+        "files":           proj.get("files",  {}),
+        "screenshots":     proj.get("screenshots", {}),
+        "context_presets": proj.get("context_presets", {}),
+        "discussion":      {
+            "roles":   disc_sec.get("roles", []),
+            "history": history,
+        },
+    }
+```
+
+**Top-level keys** (the `Metadata` dict): `project`, `output`, `files`, `screenshots`, `context_presets`, `discussion`
+
+**Sub-keys observed in `aggregate.run()`** (`src/aggregate.py:484-525`):
+
+| Top-level key | Sub-key | Access pattern |
+|---|---|---|
+| `project` | `name` | `config.get("project", {}).get("name")` |
+| `project` | `summary_only` | `config.get("project", {}).get("summary_only", False)` |
+| `project` | `execution_mode` | `config.get("project", {}).get("execution_mode", "standard")` |
+| `output` | `namespace` | `config.get("output", {}).get("namespace", "project")` |
+| `output` | `output_dir` | `config["output"]["output_dir"]` (REQUIRED — direct subscript, not `.get`) |
+| `files` | `base_dir` | `config["files"]["base_dir"]` (REQUIRED) |
+| `files` | `paths` | `config["files"].get("paths", [])` |
+| `screenshots` | `base_dir` | `config.get("screenshots", {}).get("base_dir", ".")` |
+| `screenshots` | `paths` | `config.get("screenshots", {}).get("paths", [])` |
+| `discussion` | `roles` | (passed through; not consumed by aggregate.run directly) |
+| `discussion` | `history` | `config.get("discussion", {}).get("history", [])` |
+| `context_presets` | (opaque dict) | (passed through to other consumers; not consumed by aggregate.run) |
+
+`output_dir` and `files.base_dir` are accessed via **direct subscript** (`config["output"]["output_dir"]`, `config["files"]["base_dir"]`). All other fields use `.get()` with defaults. **Both patterns must be supported** by the dataclass design.
+
+---
+
+## Tier 2's design choice (recommended)
+
+Use **6 top-level sub-dataclasses**, one per top-level key. Each sub-dataclass has its own fields. This matches the actual nested structure of `flat_config`.
+
+```python
+# src/models.py — add after existing dataclasses
+

+
+
+@dataclass(frozen=True, slots=True)

+    base_dir: str = "."
+    paths:    tuple[str, ...] = ()

+    def to_dict(self) -> Metadata:
+        """Convert back to the dict shape for backward compat with consumers

+                "history": list(self.discussion.history),
+            },
+        }

+
+Then `flat_config()` becomes:

+```python

+            history=tuple(history),
+        ),
+    )
+```
+
+---
+
+## Migration strategy (consumer side)
+
+There are 8 consumer call sites of `flat_config()`:
+- `src/aggregate.py:536`
+- `src/api_hooks.py:173`
+- `src/app_controller.py:4023, 4583, 4691, 4704, 4805`
+- `src/gui_2.py:4456`
+- `src/orchestrator_pm.py:133`
+
+Plus 2 test mocks:
+- `tests/test_context_composition_decoupled.py:34`
+- `tests/test_context_preview_button.py:65`
+
+**Two migration options** (Tier 2's choice):
+
+### Option A (incremental, recommended): Add `to_dict()` to ProjectContext, leave consumers unchanged
+
+The consumers use `.get()` and `[]` patterns on the dict. The dataclass's `to_dict()` produces the same shape. So:
+
+```python
+# Before:
+flat = project_manager.flat_config(proj)
+namespace = flat.get("project", {}).get("name") or flat.get("output", {}).get("namespace", "project")
+
+# After (incremental):
+flat = project_manager.flat_config(proj)
+flat_dict = flat.to_dict()  # unchanged consumer code uses flat_dict
+namespace = flat_dict.get("project", {}).get("name") or flat_dict.get("output", {}).get("namespace", "project")
+```
+
+Then per-consumer migration: `flat = flat.to_dict()` → `flat = flat` (consumer directly uses the dataclass's `__getitem__`/`get` dict-compat methods — which already exist on the Metadata fat struct!)
+
+Wait — `ProjectContext` is NOT a Metadata. The dataclass does NOT have `__getitem__`/`get`. So consumers that do `flat.get(...)` would FAIL on the bare dataclass.
+
+**Fix:** give `ProjectContext` dict-compat methods too (or make it inherit from Metadata's pattern). But Metadata's `__getitem__` raises KeyError, and consumers use `.get()` with defaults. So `ProjectContext` needs `get()` and `__getitem__()`.
+
+```python
+@dataclass(frozen=True, slots=True)
+class ProjectContext:
+    # ... fields ...
+    
+    def __getitem__(self, key: str) -> Any:
+        return self.to_dict()[key]  # always returns the dict
+    
+    def get(self, key: str, default: Any = None) -> Any:
+        return self.to_dict().get(key, default)
+    
+    def to_dict(self) -> Metadata:
+        # ... (as above)
+```
+
+This makes `flat.get(...)` work directly without `to_dict()` calls. Consumers migrate minimally: just remove the `.get(...)` → `flat_dict.get(...)` indirection.
+
+### Option B (full migration): Migrate all 10 consumer sites to use `flat.project.name`, `flat.output.output_dir`, etc.
+
+This is more thorough but touches 10 sites. Each consumer needs:
+- Replace `flat.get("project", {}).get("name")` with `flat.project.name`
+- Replace `flat["output"]["output_dir"]` with `flat.output.output_dir`
+- Etc.
+
+Each migration is mechanical. Total work: ~40 lines across 10 files. Plus regression-guard tests.
+
+---
+
+## Recommendation
+
+**Option A** (incremental, dict-compat) is faster and lower-risk. Phase 2 just adds the dataclasses + dict-compat methods + changes `flat_config` return type. Consumer migration is deferred to a follow-up.
+
+**Option B** is the "proper" fix (per the spec's spirit) but takes longer. Consumer migration touches the same files that the spec's other VCs touch (`aggregate.py`, `app_controller.py`, etc.).
+
+**Tier 2 should pick one and document the choice in the next track commit.**
+
+---
+
+## Acceptance criteria (corrected Phase 2)
+
+After this correction is applied:
+
+| VC | Description | Verification |
+|---|---|---|
+| VC8 (corrected) | `flat_config` returns typed `ProjectContext` | `from src.models import ProjectContext; from src.project_manager import flat_config; from src.models import Metadata; proj = Metadata(); ctx = flat_config(proj); assert isinstance(ctx, ProjectContext)` |
+| VC8 (corrected) | All 6 sub-dataclasses exist | `from src.models import ProjectMeta, ProjectOutput, ProjectFiles, ProjectScreenshots, ProjectDiscussion, ProjectContext; assert all 6 importable` |
+| VC8 (corrected) | Consumers unchanged (Option A) | `tests/test_project_manager_*.py` all pass without modification |
+| VC8 (corrected) | Dict-compat works | `ctx = flat_config(Metadata()); assert ctx.get("project") == {}  # default empty; or matches proj.get("project"))` |
+| VC8 (corrected) | `output_dir` REQUIRED field works | `flat_config(Metadata())` returns `ProjectContext` with `output.output_dir = ""` (the empty default); aggregate.run would fail with clear error when output_dir is empty (existing behavior, not a regression) |
+
+---
+
+## File locations
+
+- `src/models.py` — add 6 new dataclasses (after existing dataclasses in the file)
+- `src/project_manager.py` — change `flat_config` return type from `Metadata` to `ProjectContext`
+- `src/aggregate.py` — NO CHANGE (Option A) or migrate to use sub-dataclass access (Option B)
+- `tests/test_project_context_20260627.py` — NEW regression-guard test file with 8+ tests covering the dataclass + dict-compat methods
+

+# Plan: cruft_elimination_20260627 (EXTREME DETAIL)
+
+> **Tier 1 exhaustive plan — 2026-06-27.** This plan is the EXECUTABLE CONTRACT for Tier 2/Tier 3. Every task has exact file:line refs, exact before/after code, exact test commands, and explicit FIX-IF-FAILS steps. NEVER use `git restore`, `git checkout --`, `git reset`, or `git revert` (per AGENTS.md hard ban). NEVER use the word "REVERT" — always "MODIFY" or "FIX".
+>
+> **Prerequisites:** `type_alias_unfuck_20260626` SHIPPED (Phases 0-10 done; 67 `.get()` sites reduced to <15; all 12 per-aggregate dataclasses have `from_dict()` methods).
+>
+> **Baseline (measured 2026-06-27, master `b096a8be`):**
+> - `Metadata: TypeAlias = dict[str, Any]` STILL exists at `src/type_aliases.py:6`
+> - `hasattr(f, 'path')` checks: ~14 sites in `src/app_controller.py`
+> - `hasattr(f, '...')` checks (entity dispatch): 14 sites
+> - `Optional[T]` return types: ~25+ in `src/*.py`
+> - `Any` parameter types: ~15+ in `src/*.py`
+> - `dict[str, Any]` parameter types: ~20+ in `src/*.py`
+> - `def _do_generate(self) -> tuple[str, Path, list[Metadata], ...]` — wrong return type at `src/app_controller.py:4006`
+> - `self.files: List[models.FileItem]` declared but holds dicts (`src/app_controller.py:1996-2003`)
+> - `flat_config(...)` returns `dict` not typed
+> - `rag_engine.search()` returns `List[Dict]` not `List[RAGChunk]`
+> - Effective codepaths: ~1e+21 (down from 4.014e+22 after unfuck)
+>
+> **Acceptance:** all 14 VCs from `conductor/tracks/cruft_elimination_20260627/spec.md` PASS. Effective codepaths < 1e+18 (4+ orders of magnitude drop from baseline 4.014e+22).

+
+## §Phase 1: Promote `Metadata` from `TypeAlias = dict[str, Any]` to a typed fat struct
+
+> **[x] COMPLETE** [commit 75eb6dbb] — Metadata is now `@dataclass(frozen=True, slots=True)` with 36 explicit fields; `Metadata: TypeAlias = dict[str, Any]` removed. Dict-compat methods (`__getitem__`, `get`, `__contains__`, `__iter__`, `keys`, `values`, `items`) keep existing call sites working during the migration. 133 tests pass; audit_weak_types --strict OK (107 <= 112).
+
+**WHERE:** `src/type_aliases.py:6`
+
+**Current state (line 6):**
+```python
+Metadata: TypeAlias = dict[str, Any]
+```
+
+**Task 1.1:** Replace with a `@dataclass(frozen=True, slots=True)` containing the wire-format fields observed at all `Metadata` access sites across `src/*.py`.
+
+**Pattern (the fat struct):**
+
+```python
+@dataclass(frozen=True, slots=True)
+class Metadata:
+    """The wire-format boundary type. ONLY used at TOML/JSON parse functions.
+    Internal code uses componentized dataclasses (CommsLogEntry, FileItem, etc.)."""
+    # TOML/JSON wire keys observed in the codebase
+    paths:       Metadata = field(default_factory=dict)
+    project:     Metadata = field(default_factory=dict)
+    discussion:  Metadata = field(default_factory=dict)
+    # Per-vendor chat message keys
+    role:        str = ""
+    content:     Any = None
+    tool_calls:  Metadata = field(default_factory=list)
+    tool_call_id: str = ""
+    name:        str = ""
+    # Session log / MMA telemetry keys
+    ts:          str = ""
+    kind:        str = ""
+    direction:   str = ""
+    model:       str = "unknown"
+    source_tier: str = "main"
+    error:       str = ""
+    # MMA ticket keys
+    id:          str = ""
+    description: str = ""
+    status:      str = "todo"
+    depends_on:  tuple = ()
+    manual_block: bool = False
+    # RAG result keys (top-level, not nested)
+    document:    str = ""
+    path:        str = ""
+    score:       float = 0.0
+    # Tool definition + tool call keys
+    function:    Metadata = field(default_factory=dict)
+    args:        Metadata = field(default_factory=dict)
+    script:      str = ""
+    output:      str = ""
+    type:        str = ""
+    description: str = ""
+    parameters:  Metadata = field(default_factory=dict)
+    auto_start:  bool = False
+    # File item keys
+    view_mode:   str = "full"
+    custom_slices: Metadata = field(default_factory=list)
+    # Token usage keys
+    input_tokens:  int = 0
+    output_tokens: int = 0
+    cache_read_input_tokens:    int = 0
+    cache_creation_input_tokens: int = 0
+    # Generic pass-through (the boundary accepts arbitrary keys; from_dict filters)
+    metadata:    Metadata = field(default_factory=dict)
+
+    def to_dict(self) -> dict[str, Any]:
+        return {k: v for k, v in self.__dict__.items() if v not in (None, "", [], {}, 0, 0.0, False) or k in _NON_NULL_FIELDS}
+
+    @classmethod
+    def from_dict(cls, raw: dict[str, Any]) -> "Metadata":
+        valid = {f.name for f in fields(cls)}
+        return cls(**{k: v for k, v in raw.items() if k in valid})
+```
+
+Add `_NON_NULL_FIELDS = {"model"}` at module top (these fields are always included even when default).
+
+**HOW:** `manual-slop_py_update_definition` with `name="Metadata"`. Anchor on the existing `Metadata: TypeAlias = dict[str, Any]` line. Replace with the dataclass above.
+
+**Add import:**
+```python
+from dataclasses import dataclass, field, fields
+```
+
+**SAFETY:**
+```bash
+uv run python -c "from src.type_aliases import Metadata; m = Metadata(role='user', content='hi'); print(m.role, m.content, m.model)"
+# Expect: user hi unknown
+uv run python -c "from src.type_aliases import Metadata; m = Metadata.from_dict({'role': 'user', 'unknown_key': 'x'}); print(m.role, m.model)"
+# Expect: user unknown (unknown_key filtered)
+uv run python -m pytest tests/test_type_aliases.py -x --timeout=60
+# Expect: all pass
+uv run python scripts/audit_weak_types.py --strict
+# Expect: exit 0 (no new dict[str, Any] types)
+```
+
+**MODIFY-IF-FAILS:**
+- If pytest fails: the dataclass has a field with the wrong type. Check the field type vs the constructor arg.
+- If audit fails: a new `dict[str, Any]` field type was introduced. Replace with a specific type.
+
+**COMMIT:** `refactor(type_aliases): promote Metadata from dict[str, Any] to typed fat struct`
+
+**Commit message body MUST include:**
+```
+Phase 1: Metadata promotion
+Before: 1 TypeAlias = dict[str, Any] site in src/type_aliases.py
+After:  0 (replaced by @dataclass(frozen=True, slots=True))
+Delta:  -1 (expected: -1)
+
+Metadata is now the typed fat struct at the wire boundary.
+```
+
+**GIT NOTE:** Metadata is now `@dataclass(frozen=True, slots=True)` with explicit fields covering all observed wire-format keys. Used ONLY at the literal TOML/JSON parse functions. Internal code uses componentized dataclasses.
+
+## §Phase 2: Add `ProjectContext` dataclass for `flat_config`
+
+> **[x] COMPLETE** [commit 805a0619] — Per SPEC_CORRECTION_phase_2.md (Option A: incremental, dict-compat). Added 6 sub-dataclasses (ProjectMeta, ProjectOutput, ProjectFiles, ProjectScreenshots, ProjectDiscussion, ProjectContext) + EMPTY_PROJECT_CONTEXT sentinel. `flat_config` returns ProjectContext. Dict-compat methods (`__getitem__`, `get`) keep consumers unchanged. 10 new regression tests in `tests/test_project_context_20260627.py`; all pass.
+
+**WHERE:**
+- `src/project_manager.py:flat_config` — currently returns `dict[str, Any]`
+- All consumers (search for `flat_config` calls in `src/app_controller.py` and `src/gui_2.py`)
+
+**Task 2.1:** Add `ProjectContext` dataclass to `src/models.py` (next to `ProjectConfig`).
+
+**Pattern:**
+
+```python
+@dataclass(frozen=True, slots=True)
+class ProjectContext:
+    """The flattened project context returned by project_manager.flat_config().
+    The TOML/JSON config is parsed to Metadata at the boundary, then
+    ProjectContext.from_dict() converts to this typed form."""
+    paths:       Metadata = field(default_factory=dict)
+    project:     Metadata = field(default_factory=dict)
+    discussion:  Metadata = field(default_factory=dict)
+    files:       Metadata = field(default_factory=dict)
+    screenshots: Metadata = field(default_factory=dict)
+    context_presets: Metadata = field(default_factory=dict)
+    rag:         Metadata = field(default_factory=dict)
+    personas:    Metadata = field(default_factory=dict)
+    mma:         Metadata = field(default_factory=dict)
+
+    def to_dict(self) -> Metadata:
+        return dict(self.__dict__)
+
+    @classmethod
+    def from_dict(cls, raw: Metadata) -> "ProjectContext":
+        valid = {f.name for f in fields(cls)}
+        return cls(**{k: v for k, v in raw.items() if k in valid})
+```
+
+**Task 2.2:** Update `flat_config` in `src/project_manager.py`.
+
+Read the current implementation:
+```bash
+git grep -nA 30 "def flat_config" -- 'src/project_manager.py'
+```
+
+Identify the dict keys it returns. Add them as fields to `ProjectContext`. Update the return type annotation.
+
+**Pattern (return type + body):**
+
+```python
+def flat_config(self, ...) -> ProjectContext:
+    ...
+    return ProjectContext.from_dict(raw_dict)
+```
+
+**Task 2.3:** Update consumers in `src/app_controller.py` and `src/gui_2.py`.
+
+Search for `flat_config(` calls:
+```bash
+git grep -nE "flat_config\(" -- 'src/*.py'
+```
+
+For each consumer, replace `flat.get('key', default)` with `flat.key or default`. The `flat` variable becomes `ProjectContext` typed.
+
+**Example:**
+```python
+# BEFORE:
+flat = project_manager.flat_config(self.project, ...)
+flat["files"] = copy.copy(flat.get("files", {}))
+flat["files"]["paths"] = self.context_files
+context_block += flat.get("screenshots", {}).get("paths", [])
+
+# AFTER:
+ctx = project_manager.flat_config(self.project, ...)
+ctx_files = ProjectFiles(paths=self.context_files, base_dir=...)
+ctx = dataclasses.replace(ctx, files=asdict(ctx_files))
+context_block = ctx.screenshots.paths
+```
+
+(Read each site first; the actual replacement depends on the surrounding code.)
+
+**HOW:** `manual-slop_edit_file` per site.
+
+**SAFETY:**
+```bash
+git grep -nE "flat\.get\(" -- 'src/app_controller.py' 'src/gui_2.py' | wc -l
+# Expect: 0
+uv run python -m pytest tests/test_project_serialization.py tests/test_app_controller.py tests/test_gui_2.py -x --timeout=120
+# Expect: all pass
+```
+
+**MODIFY-IF-FAILS:**
+- If grep shows non-zero: search for missed sites. Add additional migrations.
+- If pytest fails: STOP. Read the failure. Likely cause: `flat_config` returns dict in some paths, dataclass in others. Fix the return to be consistent.
+
+**COMMIT:** `refactor(project_manager,app_controller,gui_2): introduce ProjectContext dataclass, type flat_config return`
+
+**Commit message body MUST include:**
+```
+Phase 2: ProjectContext
+Before: flat.get(...) sites in app_controller.py + gui_2.py
+After:  0 (all replaced with attribute access on ProjectContext)
+Delta:  -N
+```
+
+## §Phase 3: Fix `self.files` in `src/app_controller.py` (FR4 row 1)
+
+**WHERE:**
+- `src/app_controller.py:1101` (declaration: `self.files: List[models.FileItem] = []`)
+- `src/app_controller.py:1996-2003` (append paths: 3 branches, appends dict OR FileItem)
+- `src/app_controller.py:3226-3233` (same pattern, second occurrence)
+- `src/app_controller.py:2539` (`self.files.append(item)` — needs verification of `item` type)
+
+**Task 3.1:** Replace the 3-branch append logic with explicit type checks + single `from_dict` call.
+
+**Pattern (replacing `src/app_controller.py:1996-2003`):**
+
+```python
+# BEFORE:
+self.files = []
+for p in paths:
+    self.files.append(p)                          # ← appends raw dict
+    self.files.append(models.FileItem.from_dict(p)) # ← appends FileItem
+    self.files.append(models.FileItem(path=str(p)))  # ← appends FileItem
+
+# AFTER:
+self.files = [models.FileItem.from_path(p) for p in paths]
+```
+
+Where `models.FileItem.from_path` is a new classmethod:
+```python
+@classmethod
+def from_path(cls, p: str | Metadata | "FileItem") -> "FileItem":
+    if isinstance(p, cls):
+        return p
+    if isinstance(p, str):
+        return cls(path=p)
+    if isinstance(p, dict):
+        return cls.from_dict(p)
+    raise TypeError(f"FileItem.from_path: expected str, dict, or FileItem; got {type(p).__name__}")
+```
+
+Add this `from_path` classmethod to `src/models.py:FileItem` class.
+
+**Task 3.2:** Same fix at `src/app_controller.py:3226-3233`.
+
+**Task 3.3:** Remove `hasattr(f, 'path')` defensive checks throughout `src/app_controller.py`.
+
+Affected sites (read each first):
+- `src/app_controller.py:263` — `[f.path if hasattr(f, "path") else f.get("path") if isinstance(f, dict) else str(f) for f in controller.last_file_items]`
+- `src/app_controller.py:1767` — `return [f.path if hasattr(f, 'path') else str(f) for f in self.files]`
+- `src/app_controller.py:1771` — `old_files = {f.path: f for f in self.files if hasattr(f, 'path')}`
+- `src/app_controller.py:2536` — `next((f for f in self.files if (f.path if hasattr(f, "path") else str(f)) == file_path), None)`
+- `src/app_controller.py:3129,3182` — `file_items_as_dicts = [{"path": f.path if hasattr(f, "path") else str(f)} for f in self.files]`
+
+**Pattern (per site):**
+

+
+# AFTER:

+```
+
+After Phase 3, `self.files` is GUARANTEED `List[FileItem]`. Every `hasattr(f, 'path')` check is redundant. Remove it.
+
+**SAFETY:**
+```bash

+# Expect: 0
+uv run python -m pytest tests/test_file_item_model.py tests/test_app_controller.py tests/test_custom_slices_annotations.py tests/test_gui_2.py -x --timeout=120
+# Expect: all pass
+```
+
+**MODIFY-IF-FAILS:**
+- If grep shows non-zero: search for missed sites. The pattern is `hasattr(f, 'path')` or `hasattr(f, "path")`.
+- If pytest fails: STOP. Read the failure. Likely cause: a dict is still being added to `self.files` somewhere. Trace the path.
+
+**COMMIT:** `refactor(app_controller): self.files is now List[FileItem]; remove all hasattr defensive checks`
+
+**Commit message body MUST include:**
+```
+Phase 3: self.files type guarantee
+Before: 7 hasattr(f, 'path') sites in src/app_controller.py
+After:  0 (self.files is now List[FileItem] guaranteed)
+Delta:  -7
+```
+
+## §Phase 4: Fix `_do_generate` return type (FR4 row 2)
+
+**WHERE:**
+- `src/app_controller.py:4006` — `def _do_generate(self) -> tuple[str, Path, list[Metadata], str, str]:`
+- `src/gui_2.py` callers — find all `_do_generate(` calls
+
+**Task 4.1:** Read the current return statement at `src/app_controller.py:4051`:
+
+```python
+return full_md, path, file_items, stable_md, discussion_text
+```
+
+The `file_items` is `List[FileItem]` (from `aggregate.run`'s return). The return type annotation is wrong.
+
+**Pattern:**
+
+```python
+# BEFORE:
+def _do_generate(self) -> tuple[str, Path, list[Metadata], str, str]:
+    ...
+    return full_md, path, file_items, stable_md, discussion_text
+
+# AFTER:
+def _do_generate(self) -> tuple[str, Path, list[FileItem], str, str]:
+    ...
+    return full_md, path, file_items, stable_md, discussion_text
+```
+
+**Task 4.2:** Update `src/gui_2.py` callers.
+
+Search for `_do_generate(`:
+```bash
+git grep -nE "_do_generate\(" -- 'src/gui_2.py'
+```
+
+For each caller, the receiver variable is now `list[FileItem]`. Replace `.get('path', 'attachment')` accesses (if any) with `f.path` direct access.
+
+**SAFETY:**
+```bash
+git grep -nE "list\[Metadata\]" -- 'src/app_controller.py' | wc -l
+# Expect: 0 (was: 1 at line 4006)
+uv run python -m pytest tests/test_context_composition_decoupled.py tests/test_tiered_aggregation.py tests/test_gui_2.py -x --timeout=120
+# Expect: all pass
+```
+
+**MODIFY-IF-FAILS:**
+- If grep shows non-zero: search for the type annotation. Fix.
+- If pytest fails: STOP. Likely cause: `aggregate.run` returns `List[Dict]` in some paths. Trace.
+
+**COMMIT:** `refactor(app_controller,gui_2): _do_generate returns list[FileItem], not list[Metadata]`
+
+**Commit message body MUST include:**
+```
+Phase 4: _do_generate return type
+Before: 1 list[Metadata] annotation at src/app_controller.py:4006
+After:  0 (changed to list[FileItem])
+Delta:  -1
+```
+
+## §Phase 5: Fix `rag_engine.search()` return type (FR4 row 7)
+
+**WHERE:**
+- `src/rag_engine.py:367` — `def search(self, ...) -> List[Dict[str, Any]]:`
+- 3 consumers: `src/aggregate.py:3259`, `src/app_controller.py:251`, `src/app_controller.py:4162`
+
+**Task 5.1:** Change `rag_engine.search()` return type.
+
+**Read first:**
+```bash
+git grep -nA 20 "def search" -- 'src/rag_engine.py'
+```
+
+**Pattern (the wire format mismatch):**
+
+The wire format from the RAG store has `metadata.path` nested (or `metadata.source`); the `RAGChunk` dataclass has `path` at top-level. The `from_dict` classmethod must normalize:
+
+```python
+@classmethod
+def from_dict(cls, raw: dict[str, Any]) -> "RAGChunk":
+    if "metadata" in raw and isinstance(raw.get("metadata"), dict):
+        meta = raw["metadata"]
+        return cls(
+            document=raw.get("document", "") or meta.get("document", ""),
+            path=meta.get("path", "") or meta.get("source", "") or raw.get("path", ""),
+            score=1.0 - float(raw.get("distance", 0.0)),
+            metadata=meta,
+        )
+    valid = {f.name for f in fields(cls)}
+    return cls(**{k: v for k, v in raw.items() if k in valid})
+```
+
+(Already implemented per Phase 0 of metadata_promotion; verify it handles the wire format.)
+
+**Change `search` return type:**
+
+```python
+# BEFORE:
+def search(self, ...) -> List[Dict[str, Any]]:
+
+# AFTER:
+def search(self, ...) -> List[RAGChunk]:
+    ...
+    return [RAGChunk.from_dict(raw) for raw in raw_results]
+```
+
+**Task 5.2:** Update 3 consumers.
+
+```python
+# BEFORE:
+context_block += f"### Chunk {i+1} (Source: {path})\n{chunk.get('document', '')}\n\n"
+
+# AFTER:
+context_block += f"### Chunk {i+1} (Source: {path})\n{chunk.document}\n\n"
+```
+
+**SAFETY:**
+```bash
+git grep -nE "chunk\.get\('document'," -- 'src/aggregate.py' 'src/app_controller.py' 'src/ai_client.py' | wc -l
+# Expect: 0
+uv run python -m pytest tests/test_rag_engine.py tests/test_rag_phase4_final_verify.py tests/test_rag_chunk.py -x --timeout=120
+# Expect: all pass
+```
+
+**MODIFY-IF-FAILS:**
+- If grep shows non-zero: search for missed sites.
+- If pytest fails: STOP. The `RAGChunk.from_dict()` may not handle all wire format edge cases. Add more normalization logic.
+
+**COMMIT:** `refactor(rag_engine,aggregate,app_controller): rag_engine.search returns List[RAGChunk]`
+
+**Commit message body MUST include:**
+```
+Phase 5: RAGChunk return type
+Before: 1 List[Dict[str, Any]] at src/rag_engine.py + 3 chunk.get('document',...) consumers
+After:  0 (rag_engine.search returns List[RAGChunk] directly)
+Delta:  -1 + -3 = -4 sites
+```
+
+## §Phase 6: Eliminate `Optional[T]` returns (FR5)
+
+**WHERE:** Search all `src/*.py` for `-> Optional[`:
+
+```bash
+git grep -nE "-> Optional\[" -- 'src/*.py'
+```
+
+For each `Optional[T]` return:
+
+**Pattern (the rule per `error_handling.md`):**
+
+```python
+# BAD:
+def find_ticket(self, id: str) -> Optional[Ticket]:
+    for t in self.active_tickets:
+        if t.id == id: return t
+    return None
+
+# GOOD (preferred — NIL_T sentinel):
+def find_ticket(self, id: str) -> Ticket:
+    for t in self.active_tickets:
+        if t.id == id: return t
+    return NIL_TICKET   # zero-initialized frozen dataclass; safe to read fields
+
+# ALSO GOOD (Result pattern, when caller needs to know success/failure):
+def find_ticket(self, id: str) -> Result[Ticket]:
+    for t in self.active_tickets:
+        if t.id == id: return Result(data=t)
+    return Result(data=NIL_TICKET, errors=[ErrorInfo(kind=ErrorKind.NOT_FOUND, ...)])
+```
+
+**Required additions to `src/type_aliases.py` (NIL_T sentinels):**
+
+```python
+# Add to src/type_aliases.py after the existing dataclasses:
+NIL_COMMS_LOG_ENTRY = CommsLogEntry()
+NIL_HISTORY_MESSAGE = HistoryMessage()
+NIL_TICKET = Ticket(id="", description="", status="missing", manual_block=False)
+NIL_FILE_ITEM = FileItem(path="")
+NIL_TOOL_CALL = ToolCall(id="", function=ToolCallFunction(name="", arguments=""))
+NIL_CHAT_MESSAGE = ChatMessage(role="", content="")
+NIL_USAGE_STATS = UsageStats(input_tokens=0, output_tokens=0)

+NIL_PROVIDER_PAYLOAD = ProviderPayload()
+NIL_UI_PANEL_CONFIG = UIPanelConfig()
+NIL_PATH_INFO = PathInfo()
+NIL_TOOL_DEFINITION = ToolDefinition()
+```
+
+**Sites to fix (categorized by the kind of `Optional[T]`):**
+
+Per-file. Read each site first. Apply the pattern above.
+
+**SAFETY:**
+```bash
+git grep -cE "-> Optional\[" -- 'src/*.py'
+# Expect: 0
+uv run python scripts/audit_optional_in_3_files.py --strict
+# Expect: exit 0 (the 3 refactored files already have it)

+uv run python -m pytest tests/ -x --timeout=120 -q 2>&1 | tail -5
+# Expect: 10/11 batched tiers PASS
+```
+
+**MODIFY-IF-FAILS:**
+- If grep shows non-zero: search for missed sites. Each site needs explicit type replacement.
+- If pytest fails: STOP. Likely cause: a consumer had `if x is None: ...` checks that no longer apply after the type changed. Update consumers.
+
+**COMMIT:** `refactor(*): eliminate Optional[T] returns; add NIL_T sentinels`
+
+**Commit message body MUST include:**
+```
+Phase 6: Optional[T] elimination
+Before: N -> Optional[...] annotations across src/*.py
+After:  0 (replaced with NIL_T sentinels or Result[T])

+```
+
+## §Phase 7: Eliminate `Any` and `dict[str, Any]` from internal function signatures (FR6)
+
+**WHERE:** Search all `src/*.py` for `Any` and `dict[str, Any]` in function signatures:
+
+```bash
+git grep -nE "def .+\(.*: (Any|dict\[str, Any\])" -- 'src/*.py'
+```
+
+**Boundary function exception:** functions that take wire input (TOML/JSON parsing) may keep `dict[str, Any]` with a comment explaining it's the boundary. Examples:
+
+```python
+# Boundary function (OK):
+def _parse_wire_payload(raw: dict[str, Any]) -> ChatMessage:
+    """Boundary: parse JSON wire dict to typed ChatMessage. ONLY called from src/api_hooks.py."""
+    return ChatMessage.from_dict(raw)
+
+# Internal function (BANNED):
+def process_comms_entry(self, entry: dict[str, Any]) -> None:  # ← FIX
+    ...
+```
+
+**Pattern (per site):**
+
+```python
+# BEFORE:
+def process_comms_entry(self, entry: dict[str, Any]) -> None:
+    ...
+
+# AFTER:
+def process_comms_entry(self, entry: CommsLogEntry) -> None:

+# Expect: 10/11 batched tiers PASS
+```
+
+**MODIFY-IF-FAILS:**
+- If grep shows non-zero in internal files: classify the site. If it's a real internal function, type the parameter. If it's a boundary function, add a `"""Boundary: ..."""` docstring.
+- If pytest fails: STOP. A signature change broke a caller. Update the caller.
+
+**COMMIT:** `refactor(*): eliminate Any and dict[str, Any] from internal function signatures`
+
+**Commit message body MUST include:**

+Phase 7: Any + dict[str, Any] elimination
+Before: N function signatures with Any or dict[str, Any] in internal files

+
+## Metadata usage per file
+
+| File | Count | Classification | Justification |
+|---|---|---|---|
+| src/api_hooks.py | ~10 | BOUNDARY | HTTP entry; receives raw JSON |
+| src/project_manager.py | ~5 | BOUNDARY | TOML config loader |
+| src/session_logger.py | ~3 | BOUNDARY | JSON-L log writer |
+| src/preset*.py | ~3 | BOUNDARY | TOML preset loader |
+| src/personas.py | ~2 | BOUNDARY | TOML persona loader |
+| src/mcp_client.py | ~2 | BOUNDARY | MCP wire protocol |
+| (any internal file) | 0 | INTERNAL | BANNED — internal functions take typed dataclasses |
+
+## Why this is the boundary
+
+`Metadata` is the typed fat struct for the wire schema. It's used ONLY at:
+- TOML config loaders (`tomllib.load()` → `Metadata.from_dict(...)`)
+- JSON wire parsers (`json.loads()` → `Metadata.from_dict(...)`)
+- Vendor SDK response parsers (after parsing the SDK's response)
+
+Every consumer of these boundary functions IMMEDIATELY converts to a componentized dataclass (ProjectContext, CommsLogEntry, etc.) via `from_dict()`.
+
+## Per-site justification
+
+[list every Metadata usage with the function name + justification]

+
+## §Acceptance Criteria (Definition of Done)
+
+| # | Criterion | Verification |
+|---|---|---|
+| VC1 | `Metadata` is `@dataclass(frozen=True, slots=True)` (typed fat struct) | `git grep -A 1 "^class Metadata" src/type_aliases.py` shows `@dataclass(frozen=True, slots=True)` |
+| VC2 | Zero `TypeAlias = dict[str, Any]` for Metadata | `git grep "^Metadata: TypeAlias" src/type_aliases.py` returns nothing |
+| VC3 | Zero `dict[str, Any]` parameter types in internal files | `git grep -cE "def .+\(.*: dict\[str, Any\]" -- 'src/app_controller.py' 'src/gui_2.py' 'src/aggregate.py' 'src/multi_agent_conductor.py' 'src/mcp_client.py' 'src/ai_client.py' 'src/rag_engine.py' 'src/models.py'` returns 0 |
+| VC4 | Zero `Any` parameter types in internal files | same grep with `: Any` returns 0 |
+| VC5 | Zero `Optional[T]` return types | `git grep -cE "-> Optional\[" -- 'src/*.py'` returns 0 |
+| VC6 | Zero `hasattr(f, ...)` entity dispatch checks | `git grep -cE "hasattr\(f, '(path\|source_tier\|content\|role\|model\|id\|status)'\)" -- 'src/*.py'` returns 0 |
+| VC7 | `self.files` is always `List[FileItem]` | The 7 `hasattr(f, 'path')` sites in `src/app_controller.py` are removed; `self.files.append(...)` paths use `FileItem.from_path(...)` |
+| VC8 | `flat_config` returns typed `ProjectContext` | New dataclass exists; return type fixed |
+| VC9 | `rag_engine.search()` returns `List[RAGChunk]` | Return type fixed; 3 consumers updated |
+| VC10 | All 7 audit gates pass `--strict` | All exit 0 |
+| VC11 | 10/11 batched test tiers PASS | `scripts/run_tests_batched.py` → 10/11 |
+| VC12 | Effective codepaths < 1e+18 | 4+ orders of magnitude drop |
+| VC13 | Boundary layer audit written | `docs/reports/boundary_layer_20260628.md` exists |
+| VC14 | The 12 per-aggregate dataclasses used at their specific paths | Direct attribute access everywhere |
+
+## §Tier 2 / Tier 3 Hard Rules
+
+1. **NEVER use `git restore`, `git checkout --`, `git reset`, or `git revert`.** Per AGENTS.md hard ban. NEVER use the word "REVERT" — always "MODIFY" or "FIX". If something is wrong, add more migrations or amend the commit. Do NOT throw away work.
+
+2. **NEVER introduce `dict[str, Any]`, `Any`, or `Optional[T]` in non-boundary code.** The boundary is 2-3 functions per file. Internal code uses typed dataclasses.
+
+3. **NEVER use `hasattr()` for entity type dispatch.** The type system guarantees the entity type. Use `isinstance()` against a typed Union, or refactor so no dispatch is needed.
+
+4. **NEVER classify a phase as "no-op".** Each phase has work; do the work. If the work was already done by a previous attempt, verify it's done correctly and amend the commit.
+
+5. **NEVER add comments to source code.** Per AGENTS.md. Documentation lives in `/docs`.
+
+6. **NEVER use the native `edit` tool on Python files.** Use `manual-slop_edit_file`, `manual-slop_py_update_definition`, `manual-slop_py_add_def`, or `manual-slop_set_file_slice`.
+
+7. **NEVER create new `src/<thing>.py` files.** Per AGENTS.md.
+
+8. **NEVER skip a failing test with `@pytest.mark.skip`.** Fix the bug.
+
+9. **NEVER exceed 5 nesting levels.** Extract to functions.
+
+10. **NEVER modify `src/code_path_audit*.py`.** The audit infrastructure is correct.
+
+11. **NEVER promote `Metadata: TypeAlias = dict[str, Any]`.** It's a typed fat struct (the boundary type). The TypeAlias is BANNED.
+
+12. **STOP AND ASK if any site's variable type is unclear.** Write a 1-sentence question. Wait for the user. Do not invent a reconciliation.
+
+13. **If a commit breaks more than 2 tests, STOP.** Read the failures. Identify the root cause. Fix the commit. Do not ship broken state.
+
+## §Per-Phase Tier 2 Review Checklist
+
+Before approving each phase, Tier 2 verifies:
+
+1. The commit message has "Before: N, After: M, Delta: -K" with K matching the planned count.
+2. The relevant `git grep` count decreased by exactly the planned K.
+3. The relevant `pytest` files pass.
+4. No audit gate regressed.
+5. The batched test suite still passes 10/11 tiers.
+6. No "no-op" or "REVERT" or "skipped" in the commit message.
+
+If any check fails: **DO NOT APPROVE.** Tell Tier 3 what to fix. Tier 3 fixes the migration and re-commits.
+
+## §Anti-Pattern Guard (per AGENTS.md)
+
+If you observe any of these patterns in your own work, STOP and re-read AGENTS.md:
+
+1. **The Deduction Loop**: running a test 4+ times in one investigation.
+2. **The Report-Instead-of-Fix Pattern**: writing a 200-line status report instead of fixing.
+3. **The Scope-Creep Track-Doc Pattern**: writing a 5-phase spec for a 1-line fix.
+4. **The Inherited-Cruft Pattern**: trying to "fix" a broken file from a previous agent.
+5. **No Diagnostic Noise in Production**: `sys.stderr.write` lines in `src/*.py`.
+6. **The "I Am Not Going To Attempt Another Fix" Surrender**: only after the 5-step protocol.
+7. **The Verbose-Commit-Message Pattern**: commit messages > 15 lines.
+8. **The Isolated-Pass Verification Fallacy**: verifying in isolation but not in batch.
+9. **The Workspace-Path Drift Pattern**: using `/tmp` or env vars for test paths.
+10. **The No-Op Classification Shortcut**: marking phases complete without doing the work. (banned by Hard Rule #4)
+
+## §Tier 2 Invitation Prompt
+
+Use this prompt to invoke Tier 2:
+
+```
+Track: cruft_elimination_20260627 (branch: tier2/cruft_elimination_20260627).
+
+This is the FINAL track in the metadata type-promotion chain. The previous track (type_alias_unfuck_20260626) introduced a NEW cruft: defensive isinstance() checks at function bodies. The user explicitly rejected this pattern: "every conditional check is more execution noise and tech debt."
+
+Read the EXHAUSTIVE plan at conductor/tracks/cruft_elimination_20260627/plan.md (this file).
+
+HARD RULES (NON-NEGOTIABLE):
+1. NO dict[str, Any], Any, or Optional[T] in non-boundary code. The boundary is 2-3 functions per file.
+2. NO hasattr() for entity type dispatch. The type system guarantees the entity type.
+3. NO isinstance() defensive checks at function bodies. The boundary layer does from_dict() once.
+4. NEVER use git restore, git checkout --, git reset, or git revert. NEVER use the word "REVERT" — always "MODIFY" or "FIX". If something is wrong, add more migrations or amend the commit.
+5. NO no-op classifications. Each phase has work; do the work.
+6. NO new src/<thing>.py files. NO comments in src/. NO @pytest.mark.skip.
+
+PER-PHASE HARD GUARD:
+Each phase commit message MUST include:
+  Phase N: <name>
+  Before: N <pattern> sites
+  After:  0 (or expected)
+  Delta:  -N
+
+If delta != expected, FIX the migration. Don't blow it away.

+# Track Specification: c11_python_20260628
+
+## Overview
+
+**Goal:** Make Python behave as close to C11/Odin/Jai as possible within Python's runtime constraints. Eliminate all polymorphic dicts (`dict[str, Any]`), runtime type checks (`hasattr`, `isinstance` for entity dispatch), `Optional[T]` returns, `Any` type hints, and `.get('key', default)` access on known fields from internal code.
+
+**Scope:** Promote every polymorphic dict to a typed dataclass (either a fat struct at the wire boundary OR a componentized dataclass at the specific path). Convert function signatures to declare typed parameters. Remove every `hasattr()` / `isinstance()` / `.get()` defensive check. Replace `Optional[T]` with `Result[T]` + `NIL_T` sentinels.
+
+**After this track:**
+- One literal boundary layer (`tomllib.load()` + `json.loads()` result) uses `Metadata` (a typed fat struct).
+- Everywhere else: typed componentized dataclasses (already exist from `metadata_promotion_20260624`).
+- No `dict[str, Any]` outside the boundary layer.
+- No `hasattr()` for entity type dispatch.
+- No `Optional[T]` returns.
+- No `Any` type hints.
+- The 4.01e+22 metric drops because dispatcher functions lose their polymorphic branches.
+
+## The C11/Odin/Jai Semantics in Python
+
+| C11/Odin/Jai concept | Python equivalent | What it forbids |
+|---|---|---|
+| Value type (`struct`) | `@dataclass(frozen=True, slots=True)` | Mutation, dynamic field addition |
+| Static type (`int`, `string`) | type hint + mypy | `Any`, `dict[str, Any]` outside the boundary |
+| No null | `Result[T]` + `NIL_T` sentinel | `Optional[T]`, `None` returns |
+| Direct field access (`s.field`) | `s.field` | `.get('field', default)` on known fields |
+| No dynamic dispatch (`if hasfield`) | Compile-time-typed function params | `hasattr(x, 'field')` for entity type dispatch |
+| Explicit conversion at boundary | `from_dict()` at the wire entry | Scattered `from_dict()` in consumers |
+
+## Current State Audit (after `type_alias_unfuck_20260626` ships)
+
+| Cruft source | Current count | Source |
+|---|---:|---|
+| `Metadata: TypeAlias = dict[str, Any]` (the lazy-typing escape hatch) | 1 | `src/type_aliases.py:6` |
+| `.get('key', default)` sites on known aggregates | ~15 (post-unfuck) | `git grep -cE "\.get\('[a-z_]+'," -- 'src/*.py'` |

+| Effective codepaths | 4.014e+22 | baseline |
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | `Metadata` becomes `@dataclass(frozen=True, slots=True)` (typed fat struct) | `src/type_aliases.py` shows `Metadata` as a dataclass, NOT `TypeAlias = dict[str, Any]` |
+| G2 | Zero `Metadata: TypeAlias = dict[str, Any]` | The TypeAlias is removed; only the dataclass remains |
+| G3 | Zero `dict[str, Any]` parameter types in internal code | `git grep -cE "def .+\(.*: dict\[str, Any\]" -- 'src/app_controller.py' 'src/gui_2.py' 'src/aggregate.py' 'src/multi_agent_conductor.py' 'src/mcp_client.py' 'src/ai_client.py' 'src/rag_engine.py' 'src/models.py'` returns 0 |
+| G4 | Zero `Any` parameter types in internal code | Same grep with `: Any` returns 0 |
+| G5 | Zero `Optional[T]` return types | `git grep -cE "-> Optional\[" -- 'src/*.py'` returns 0 |
+| G6 | Zero `hasattr(f, ...)` entity dispatch checks | `git grep -cE "hasattr\(f, '(path\|source_tier\|content\|role\|model\|id\|status)'\)" -- 'src/*.py'` returns 0 |
+| G7 | `self.files` is ALWAYS `List[FileItem]` (no dicts in the list) | The append paths convert dicts via `models.FileItem.from_dict(p)`; the `hasattr(f, 'path')` checks are removed |
+| G8 | `flat_config` returns `ProjectContext` (typed), not `dict` | New `ProjectContext` dataclass; `project_manager.flat_config()` returns it |
+| G9 | `rag_engine.search()` returns `List[RAGChunk]` (typed), not `List[Dict]` | Return type changed; 3 consumers updated |
+| G10 | `_do_generate` returns `list[FileItem]` (typed), not `list[Metadata]` | Return type annotation fixed |
+| G11 | All 7 audit gates pass `--strict` | All exit 0 |
+| G12 | All existing tests pass | `scripts/run_tests_batched.py` → 10/11 |
+| G13 | Effective codepaths drops by ≥ 4 orders of magnitude | `< 1e+18` (was 4.014e+22) |
+| G14 | The boundary layer is documented as exactly 2 places: TOML load + JSON parse | `docs/reports/boundary_layer_20260628.md` enumerates every `Metadata` usage with justification |
+
+## Non-Goals
+
+- Modifying the existing 12 per-aggregate dataclass definitions (their fields are correct; just need to USE them)
+- Adding new `src/<thing>.py` files
+- Creating further followup tracks (this is the FINAL track; no more layers)
+- Changing the runtime semantics of Python (we're working within Python's constraints)
+
+## Functional Requirements
+
+### FR1: The Boundary Layer is EXACTLY 2 places
+
+**Place 1: TOML config loaders** in `src/project_manager.py`, `src/preset*.py`, `src/personas.py`, `src/tool_presets.py`, `src/context_presets.py`, `src/workspace_manager.py`.
+
+The TOML loader returns `Metadata` (the typed fat struct) for the 100ns between `tomllib.load()` and the caller's `from_dict()` conversion. Every consumer of the TOML loader immediately does `ProjectContext.from_dict(loaded)`, `Persona.from_dict(loaded)`, etc.
+
+**Place 2: JSON wire parsers** in `src/api_hooks.py` (HTTP entry points) and `src/mcp_client.py` (MCP wire protocol).
+
+The JSON parser returns `Metadata` for the 100ns between `json.loads()` and the caller's `from_dict()` conversion. Every consumer immediately does `ChatMessage.from_dict(payload)`, `MMAUsageStats.from_dict(payload)`, etc.
+
+**No other code uses `Metadata`.** Every other function takes a typed componentized dataclass.
+
+### FR2: `Metadata` becomes a typed fat struct
+
+```python
+# In src/type_aliases.py:
+@dataclass(frozen=True, slots=True)
+class Metadata:
+    """The wire-format boundary type. ONLY used in TOML loaders and JSON parsers.
+    Internal code uses componentized dataclasses (CommsLogEntry, FileItem, etc.)."""
+    # TOML keys
+    paths:        Metadata = field(default_factory=dict)  # nested dict for path config
+    project:      Metadata = field(default_factory=dict)
+    discussion:   Metadata = field(default_factory=dict)
+    # JSON wire keys (per-vendor chat message)
+    role:         str = ""
+    content:      Any = None
+    tool_calls:   Metadata = field(default_factory=list)
+    tool_call_id: str = ""
+    name:         str = ""
+    # Session log keys
+    ts:           str = ""
+    kind:         str = ""
+    direction:    str = ""
+    model:        str = "unknown"
+    source_tier:  str = "main"
+    error:        str = ""
+    # MMA ticket keys
+    id:           str = ""
+    description:  str = ""
+    status:       str = "todo"
+    depends_on:   tuple = ()
+    manual_block: bool = False
+    # RAG result keys
+    document:     str = ""
+    score:        float = 0.0
+    # Tool keys
+    function:     Metadata = field(default_factory=dict)
+    args:         Metadata = field(default_factory=dict)
+    script:       str = ""
+    output:       str = ""
+    type:         str = ""
+    # Tool definition keys
+    description:  str = ""
+    parameters:   Metadata = field(default_factory=dict)
+    auto_start:   bool = False
+    # File item keys
+    path:         str = ""
+    view_mode:    str = "full"
+    custom_slices: Metadata = field(default_factory=list)
+    # Token usage keys
+    input_tokens:  int = 0
+    output_tokens: int = 0
+    cache_read_input_tokens:  int = 0
+    cache_creation_input_tokens: int = 0
+    # Generic pass-through
+    metadata:     Metadata = field(default_factory=dict)
+
+    def to_dict(self) -> Metadata:
+        return {f.name: v for f in fields(self) for v in [getattr(self, f.name)] if v not in (None, "", [], {}, 0, 0.0, False) or f.name in _NON_NULL_FIELDS}
+
+    @classmethod
+    def from_dict(cls, raw: dict[str, Any]) -> "Metadata":
+        valid = {f.name for f in fields(cls)}
+        return cls(**{k: v for k, v in raw.items() if k in valid})
+```
+
+**Why a fat struct here is OK:** the wire format (TOML/JSON) is polymorphic at the boundary. The boundary function receives arbitrary keys. After the boundary, internal code uses componentized types. The fat struct is the WIRE schema; not a lazy-typing escape hatch.
+
+### FR3: Componentize the specific paths (already exist)
+
+The 12 dataclasses already exist from `metadata_promotion_20260624`:
+
+| Dataclass | Used at | Replaces |
+|---|---|---|
+| `CommsLogEntry` | session log entries, MMA telemetry | `entry_obj = {...}` dict literals |
+| `HistoryMessage` | UI discussion history | `msg.get('role', 'unknown')` etc. |
+| `FileItem` | context composition | `flat.get('files', {}).get('paths', [])` |
+| `ToolCall` | tool loop | `tc.get('id')` / `tc['function']['name']` |
+| `ChatMessage` | provider-side history | `msg.get('role')` in send paths |
+| `UsageStats` | token usage | `u.get('input_tokens', 0)` |
+| `RAGChunk` | RAG results | `chunk.get('document', '')` |
+| `Ticket` | MMA tickets | `t.get('id', '')` / `t['depends_on']` |
+| `SessionInsights` | session stats | `insights.get('total_tokens', 0)` |
+| `DiscussionSettings` | per-turn settings | `entry.get('temperature', 0.7)` |
+| `CustomSlice` | visual slices | `slc.get('tag', '')` / `slc['start_line']` |
+| `MMAUsageStats` | per-tier usage | `stats.get('model', 'unknown')` |
+| `ProviderPayload` | script execution | `payload.get('script')` |
+| `UIPanelConfig` | panel state | `gui_cfg.get('separate_message_panel', False)` |
+| `PathInfo` | path config | `proj_paths['logs_dir']` |
+| `ToolDefinition` | tool schemas | `tinfo.get('description', '')` |
+
+**Usage rule:** at each specific path, the variable is declared as the typed dataclass. Direct attribute access. No `.get()`.
+
+### FR4: Fix the central path bugs
+
+These bugs are the source of the defensive checks:
+
+| File:line | Bug | Fix |
+|---|---|---|
+| `src/app_controller.py:1101` | `self.files: List[models.FileItem] = []` (declared) but `app_controller.py:1999-2003` appends dicts | At the append site, convert dicts via `models.FileItem.from_dict(p)`; the list is truly `List[FileItem]` |
+| `src/app_controller.py:4006` | `_do_generate(self) -> tuple[str, Path, list[Metadata], ...]` (return type wrong; actual is `list[FileItem]`) | Change return type to `list[FileItem]`; update `gui_2.py` callers |
+| `src/project_manager.py:flat_config` | returns `dict[str, Any]` | Return `ProjectContext` (new dataclass) |
+| `src/aggregate.py:96` | `f.path if hasattr(f, 'path') else str(f)` (defensive for f might be dict) | `f` is now `FileItem`; `f.path` direct |
+| `src/aggregate.py:193` | `elif hasattr(entry_raw, "path")` (defensive for entry_raw might be dict) | `entry_raw` is `FileItem`; `entry_raw.path` direct |
+| `src/aggregate.py:3259` | `chunk.get('document', '')` (RAG chunk is dict) | `chunk` is `RAGChunk`; `chunk.document` direct |
+| `src/rag_engine.py:367` | `search() -> List[Dict[str, Any]]` (return type wrong) | Return `List[RAGChunk]` |
+| `src/app_controller.py:263` | `[f.path if hasattr(f, "path") else f.get("path") ...]` | `f` is `FileItem`; `f.path` direct |
+| `src/app_controller.py:1767` | same | same |
+| `src/app_controller.py:1771` | same | same |
+| `src/app_controller.py:2536` | same | same |
+| `src/app_controller.py:3129` | same | same |
+| `src/app_controller.py:3182` | same | same |
+| `src/app_controller.py:2274` | `payload.get('script') or json.dumps(payload.get('args', {}), indent=1)` | `payload` is `ProviderPayload`; `payload.script or json.dumps(payload.args, indent=1)` |
+
+After these fixes, `git grep -cE "hasattr\(f," -- 'src/*.py'` returns 0.
+
+### FR5: Eliminate `Optional[T]` returns
+
+Per `conductor/code_styleguides/error_handling.md`:
+
+```python
+# BAD:
+def find_ticket(id: str) -> Optional[Ticket]:
+    ...
+
+# GOOD (Result pattern):
+def find_ticket(id: str) -> Result[Ticket]:
+    return Result(data=NIL_TICKET) if not found else Result(data=ticket)
+
+# BETTER (NIL sentinel):
+def find_ticket(id: str) -> Ticket:
+    ...
+    return NIL_TICKET   # zero-initialized frozen dataclass; safe to read fields
+```
+
+`NIL_TICKET` is a module-level singleton: `NIL_TICKET = Ticket(id="", description="", status="missing", manual_block=False)`. Consumers can read `ticket.id`, `ticket.status`, etc. safely — no `None` check needed.
+
+### FR6: Eliminate `Any` and `dict[str, Any]` from internal function signatures
+
+```python
+# BAD:
+def _to_typed_tool_call(tc: Any) -> ToolCall:
+    return ToolCall(id=getattr(tc, "id", "") or "", ...)
+
+# GOOD (boundary function):
+def _parse_wire_tool_call(wire: dict[str, Any]) -> ToolCall:
+    """Boundary: parse MCP wire-format dict to typed ToolCall. ONLY called from src/openai_compatible.py."""
+    return ToolCall.from_dict(wire)
+
+# INTERNAL function (already typed):
+def process_tool_call(tc: ToolCall) -> None:
+    tool_id = tc.id   # no getattr; the type is guaranteed
+```
+
+After this, every function signature in `src/app_controller.py`, `src/gui_2.py`, `src/aggregate.py`, `src/multi_agent_conductor.py`, `src/mcp_client.py` (internal functions only), `src/ai_client.py` (send methods only — boundary), `src/rag_engine.py`, `src/models.py` declares typed dataclasses (no `Any`, no `dict[str, Any]`).
+
+### FR7: The lazy-init `hasattr(self, ...)` pattern is allowed
+
+The `hasattr(self, 'perf_monitor')` checks in `src/app_controller.py` are NOT entity dispatch — they're lazy initialization. These stay (they're internal state management, not external type dispatch).
+
+But document: per `conductor/code_styleguides/python.md`, lazy init is acceptable. The DOD rule is "no runtime type dispatch for entity types" — lazy init is initialization state, not entity type.
+
+## Per-Phase Task List
+
+### Phase 0: Promote `Metadata` to typed fat struct (FR2)
+
+```bash
+# Read src/type_aliases.py current state
+# Write the new Metadata dataclass with all 30+ fields
+# Remove the TypeAlias
+# Verify: from src.type_aliases import Metadata; Metadata(role='user', content='hi')
+# Verify: Metadata.from_dict({'role': 'user'}) works
+```
+
+### Phase 1: Add new typed `ProjectContext` dataclass
+
+```bash
+# Add ProjectContext to src/models.py with all fields observed in src/project_manager.py:flat_config
+# Convert flat_config to return ProjectContext
+# Update consumers (src/app_controller.py:_do_generate, src/gui_2.py)
+```
+
+### Phase 2: Fix `self.files` in `src/app_controller.py` (FR4 row 1)
+
+```bash
+# At src/app_controller.py:1996-2003, replace the 3-line append with:
+#   for p in paths:
+#       if isinstance(p, dict):
+#           self.files.append(models.FileItem.from_dict(p))
+#       elif isinstance(p, str):
+#           self.files.append(models.FileItem(path=p))
+#       elif isinstance(p, models.FileItem):
+#           self.files.append(p)
+#       else:
+#           raise TypeError(f"unexpected file item type: {type(p)}")
+# Remove all hashr(f, 'path') checks at: 263, 1767, 1771, 2536, 3129, 3182
+```
+
+### Phase 3: Fix `_do_generate` return type (FR4 row 2)
+
+```bash
+# Change src/app_controller.py:4006 from `list[Metadata]` to `list[FileItem]`
+# Update src/gui_2.py callers (search for `_do_generate(` and verify the receiver is typed as list[FileItem])
+```
+
+### Phase 4: Fix `rag_engine.search()` return type (FR4 row 7)
+
+```bash
+# Change src/rag_engine.py:367 from `List[Dict[str, Any]]` to `List[RAGChunk]`
+# Update src/aggregate.py:3259, src/app_controller.py:251, src/app_controller.py:4162 to use chunk.document directly
+# Handle the wire format mismatch (RAGChunk expects path top-level; wire has metadata.path)
+```
+
+### Phase 5: Fix all `entry_obj = {...}` dict literals in `src/app_controller.py` (FR4 row 14)
+
+```bash
+# At src/app_controller.py:2274, replace `payload.get('script') or json.dumps(payload.get('args', {}), indent=1)` with `pp = ProviderPayload.from_dict(payload); pp.script or json.dumps(pp.args, indent=1)`
+# Same for lines 2277, 2287, 2305-2308 (already partly done)
+# Same for lines 3508 (`f['path'] for f in file_items` → `f.path for f in file_items` since f is now FileItem)
+```
+
+### Phase 6: Fix `src/aggregate.py` defensive checks (FR4 rows 5-6)
+
+```bash
+# At src/aggregate.py:96, replace `f.path if hasattr(f, 'path') else str(f)` with `f.path` (f is FileItem)
+# At src/aggregate.py:193, replace `elif hasattr(entry_raw, "path")` with `elif isinstance(entry_raw, FileItem): entry_raw.path`
+# At src/aggregate.py:3259, replace `chunk.get('document', '')` with `chunk.document` (chunk is RAGChunk)
+```
+
+### Phase 7: Eliminate `Optional[T]` returns (FR5)
+
+```bash
+# For each `Optional[T]` return in src/, replace with `Result[T]` or `NIL_T` sentinel
+# Define NIL_TICKET, NIL_COMMS_LOG_ENTRY, etc. in src/type_aliases.py
+# Update consumers to handle NIL_T (read fields directly; NIL_T is zero-initialized)
+```
+
+### Phase 8: Eliminate `Any` and `dict[str, Any]` from internal signatures (FR6)
+
+```bash
+# For each function signature with `Any` or `dict[str, Any]` parameter in internal files, change to the typed dataclass
+# For boundary functions (TOML/JSON parsers), keep `dict[str, Any]` but document with a comment that it's a boundary
+```
+
+### Phase 9: Re-measure + verification
+
+```bash
+# Cruft counts all 0
+git grep -cE "\.get\('[a-z_]+'," -- 'src/*.py'  # expect: < 15 (only collapsed-codepath)
+git grep -cE "hasattr\(f, '(path|source_tier|content|role|model|id|status)'\)" -- 'src/*.py'  # expect: 0
+git grep -cE "def .+\(.*: (Metadata|Any|dict\[str, Any\])" -- 'src/app_controller.py' 'src/gui_2.py' 'src/aggregate.py' 'src/multi_agent_conductor.py' 'src/mcp_client.py' 'src/ai_client.py' 'src/rag_engine.py' 'src/models.py'  # expect: 0
+git grep -cE "-> Optional\[" -- 'src/*.py'  # expect: 0
+git grep -cE "-> Any" -- 'src/*.py'  # expect: 0
+
+# Effective codepaths
+uv run python -c "..."  # expect: < 1e+18
+
+# 7 audit gates
+uv run python scripts/audit_weak_types.py --strict
+uv run python scripts/generate_type_registry.py --check
+# etc.
+
+# Batched tests
+uv run python scripts/run_tests_batched.py  # expect: 10/11 PASS
+```
+
+### Phase 10: Boundary layer audit + documentation
+
+```bash
+# Document every Metadata usage with justification
+git grep -nE "Metadata" -- 'src/*.py' > /tmp/metadata_usages.txt
+
+# Write docs/reports/boundary_layer_20260628.md
+# Enumerate every Metadata usage; classify as boundary (kept) or internal (must fix)
+# Expect: only the TOML loaders + JSON parsers retain Metadata
+```
+
+## Acceptance Criteria (Definition of Done)
+
+| # | Criterion | Verification |
+|---|---|---|
+| VC1 | `Metadata` is a `@dataclass(frozen=True, slots=True)` with explicit fields | `git grep -A 1 "^class Metadata" src/type_aliases.py` shows `@dataclass(frozen=True, slots=True)` |

+| VC4 | Zero `Any` parameter types in internal files | grep returns 0 |
+| VC5 | Zero `Optional[T]` return types | grep returns 0 |
+| VC6 | Zero `hasattr(f, ...)` entity dispatch checks | grep returns 0 |
+| VC7 | `self.files` is always `List[FileItem]` | `git grep -E "self\.files\.append\(" -- 'src/app_controller.py'` shows ONLY FileItem appends |
+| VC8 | `flat_config` returns typed `ProjectContext` | New dataclass exists; return type fixed |

+## Why this is the FINAL track (no more followups)

+1. **`Metadata` is a typed fat struct**, used ONLY at the literal TOML/JSON boundary (2 places in the entire codebase).
+2. **Every internal function takes a typed dataclass** — no `Any`, no `dict[str, Any]`.
+3. **No runtime type dispatch** — no `hasattr()` for entity type checks, no `isinstance()` for entity dispatch.
+4. **No null** — `Result[T]` + `NIL_T` sentinels per `error_handling.md`.
+5. **No `.get()` on known fields** — direct attribute access.
+6. **The metric drops by 4+ orders of magnitude** because dispatcher functions lose their polymorphic branches.
+
+The conventions are ENFORCED:
+- Every new function signature MUST declare typed parameters (no `Any`).
+- Every new dataclass goes in `src/type_aliases.py` (type-system) or the appropriate parent module (in-module).
+- Every wire boundary (TOML/JSON parse) is the ONLY place `Metadata` (the typed fat struct) appears.
+- Every consumer of a wire boundary IMMEDIATELY converts to a componentized dataclass via `from_dict()`.
+
+Future code that wants to receive raw data MUST:
+- Add a `from_dict()` classmethod to the appropriate dataclass (or create a new one)
+- Convert at the wire boundary
+- Internal code only sees the typed dataclass
+
+This is C11/Odin/Jai semantics in Python. As fast as Python can be.

+# Directive Hot-Swap Harness 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 a directive hot-swap harness that lets the user maintain alternative encodings of the same directive as separate files, compose them into named presets (markdown bills of materials), and hot-swap which preset is active via a single `warm with: <path>` instruction in the role prompt or session message.
+
+**Architecture:** A `conductor/directives/` directory tree where each directive is a subdirectory and each encoding variant is a file (`v1.md`, `v2_<style>.md`). Presets in `conductor/directives/presets/` are markdown files listing which variant files to read. The 5 tier role prompts are updated with a single `warm with: <preset_path>` line that replaces the hardcoded mandatory-reading list. No scripts, no TOML, no build steps — markdown-only, LLM-native.
+
+**Tech Stack:** Markdown files. No code changes. No tests (this is a documentation/tooling track, not a code track). The "test" is: does an LLM follow the `warm with:` instruction and read the listed files?
+
+**Spec:** `docs/superpowers/specs/2026-06-27-directive-hotswap-harness-design.md`

+## Phase 1: Directive Harvest
+
+Focus: Systematically comb the doc tree, extract every directive-like statement into a candidate list, resolve granularity (which to merge, split, keep standalone). This is the bulk of the work.
+
+Each task creates one or more `conductor/directives/<name>/v1.md` files. The v1 content is a verbatim lift from the source doc (not a rewrite). The variant header annotates the source location and why this iteration exists.
+
+- [ ] **Step 1.1: Harvest §17 banned patterns (7 directives)**
+
+**Files to read:**
+- `conductor/code_styleguides/python.md:216-409` (§17 Banned Patterns — the 7 banned patterns + §17.7 boundary exception + §17.8 enforcement + §17.9 local imports + §17.10 enforcement inventory)
+
+**Directives to create:**
+
+1. `conductor/directives/ban_dict_any/v1.md` — source: `python.md:220-237` (§17.1). Content: the `dict[str, Any]` ban + before/after examples + the boundary exception cross-ref.
+2. `conductor/directives/ban_any_type/v1.md` — source: `python.md:239-250` (§17.2). Content: the `Any` ban + before/after.
+3. `conductor/directives/ban_optional_returns/v1.md` — source: `python.md:252-272` (§17.3). Content: the `Optional[T]` return ban + the `Result[T]` replacement pattern.
+4. `conductor/directives/ban_hasattr_dispatch/v1.md` — source: `python.md:274-299` (§17.4). Content: the `hasattr()` for entity type dispatch ban + the typed Union alternative.
+5. `conductor/directives/ban_getattr_dispatch/v1.md` — source: `python.md:301-311` (§17.5). Content: the `getattr(x, 'field', default)` for type dispatch ban.
+6. `conductor/directives/ban_dict_get_on_known_fields/v1.md` — source: `python.md:313-323` (§17.6). Content: the `.get('field', default)` on a `dict[str, Any]` ban + direct attribute access alternative.
+7. `conductor/directives/boundary_layer_exception/v1.md` — source: `python.md:325-327` (§17.7). Content: the ONE exception — the wire boundary (TOML/JSON parse) where `dict[str, Any]` is allowed.
+
+**Variant header format** (use for ALL v1 files):
+```markdown
+# <directive_name> — v1
+
+**Why this iteration:** Lifted verbatim from `conductor/code_styleguides/python.md` §17.N (lines N-M).
+This is the baseline encoding — the style currently in production. Future variants
+will test alternative encodings (rationale-first, before/after, tabular) against this baseline.
+
+**Source:** `conductor/code_styleguides/python.md:NNN-MMM`
+
+---
+
+<verbatim directive text from the source>
+```
+
+- [ ] **Step 1.2: Harvest §17.9 import/aliasing bans (3 directives)**
+
+**Files to read:**
+- `conductor/code_styleguides/python.md:336-409` (§17.9 local imports + aliasing + repeated from_dict)
+
+**Directives to create:**
+
+8. `conductor/directives/ban_local_imports/v1.md` — source: `python.md:336-360` (§17.9a). Content: local imports inside functions are banned + the `try/except ImportError` exception + the vendor-SDK-warmup whitelist.
+9. `conductor/directives/ban_prefix_aliasing/v1.md` — source: `python.md` (§17.9b, within the 336-409 range). Content: `import X as _X` aliasing-for-naming-convenience is banned.
+10. `conductor/directives/ban_repeated_from_dict/v1.md` — source: `python.md` (§17.9c, within the 336-409 range). Content: repeated `.from_dict()` calls in the same expression are banned.
+
+- [ ] **Step 1.3: Harvest error handling conventions (2 directives)**
+
+**Files to read:**
+- `conductor/code_styleguides/error_handling.md:22-56` (the 5 patterns) + `error_handling.md:212-242` (hard rules) + `error_handling.md:274-311` (boundary types)
+
+**Directives to create:**
+
+11. `conductor/directives/result_error_pattern/v1.md` — source: `error_handling.md:22-56, 212-242`. Content: the `Result[T]` dataclass pattern (data + errors list, not `Optional[T]` + exceptions). The 5 patterns (nil-sentinel, zero-init, fail-early, AND over OR, error-info as side-channel). The hard rules (`Optional[T]` returns forbidden in baseline files; `Result[T]` for any function that can fail).
+12. `conductor/directives/nil_sentinel_pattern/v1.md` — source: `error_handling.md:24-47` (Pattern 1 — Nil-Sentinel Dataclasses). Content: the `NIL_T` singleton pattern replacing `None`. The sentinel type contract.
+
+- [ ] **Step 1.4: Harvest type/data-structure conventions (3 directives)**
+
+**Files to read:**
+- `conductor/code_styleguides/data_oriented_design.md:176-215` (§8.5 Python Type Promotion Mandate + §8.6 Boundary Layer + §8.7 C11 framing)
+- `conductor/code_styleguides/type_aliases.md:40-81` (Metadata boundary type + when to promote + when NOT to promote)
+
+**Directives to create:**
+
+13. `conductor/directives/typed_dataclass_fields/v1.md` — source: `data_oriented_design.md:176-199` (§8.5). Content: the Python Type Promotion Mandate — use typed `@dataclass(frozen=True, slots=True)` with explicit fields. The 7 banned patterns table.
+14. `conductor/directives/metadata_boundary_type/v1.md` — source: `type_aliases.md:40-81` + `data_oriented_design.md:200-215` (§8.6). Content: `Metadata` is the typed fat struct at the wire boundary, NOT `TypeAlias = dict[str, Any]`. The boundary is 2-3 functions per file. When to promote to per-aggregate dataclass vs. when to keep as collapsed codepath.
+15. `conductor/directives/boundary_layer_exception/v1.md` — UPDATE the file created in Step 1.1 to also include the `data_oriented_design.md:200-215` (§8.6) and `type_aliases.md` boundary-layer content. This directive cross-references §17.7 (the exception) + §8.6 (the boundary definition) + type_aliases.md (the Metadata-as-boundary-type rule).
+
+- [ ] **Step 1.5: Harvest code style directives (5 directives)**
+
+**Files to read:**
+- `conductor/code_styleguides/python.md:7-21` (§1 Indentation + §2 Type Annotations)
+- `conductor/code_styleguides/python.md:64-71` (§8 AI-Agent Specific Conventions — no comments, no diagnostic noise)
+- `conductor/code_styleguides/python.md:185-199` (§13 Vertical Compaction)
+- `conductor/code_styleguides/python.md:175-184` (§12 SDM)
+- `conductor/workflow.md:5-20` (Code Style section)
+
+**Directives to create:**
+
+16. `conductor/directives/one_space_indent/v1.md` — source: `python.md:7-20` + `workflow.md:7`. Content: 1-space indentation for ALL Python code. CRLF line endings on Windows. No comments unless explicitly requested.
+17. `conductor/directives/no_comments_in_body/v1.md` — source: `python.md:66` + `AGENTS.md:56`. Content: no comments in source code; documentation lives in `/docs`. Only comment on *why* when non-obvious.
+18. `conductor/directives/no_diagnostic_noise/v1.md` — source: `python.md:70` + `AGENTS.md` "No Diagnostic Noise in Production" section. Content: no `sys.stderr.write("[XYZ_DIAG] ...")` in production code. Diag goes to log files or temp scripts.
+19. `conductor/directives/type_hints_required/v1.md` — source: `python.md:24-31` + `product-guidelines.md:58`. Content: mandatory strict type hints for all parameters, return types, and global variables.
+20. `conductor/directives/sdm_dependency_tags/v1.md` — source: `python.md:175-184` (§12) + `product-guidelines.md:59`. Content: Structural Dependency Mapping tags (`[C: ...]`, `[M: ...]`, `[U: ...]`) in docstrings for AI-assisted impact analysis.
+
+- [ ] **Step 1.6: Harvest file/taxonomy conventions (3 directives)**
+
+**Files to read:**
+- `AGENTS.md:62-76` (File Size and Naming Convention HARD RULE)
+- `conductor/workflow.md:45` (File Naming Convention HARD RULE)
+- `conductor/code_styleguides/python.md:205-215` (§15 Modular Controller Pattern)
+
+**Directives to create:**
+
+21. `conductor/directives/file_naming_convention/v1.md` — source: `AGENTS.md:62-76` + `workflow.md:45`. Content: new `src/<thing>.py` files may only be created on the user's explicit request. Helpers go in the parent module. Large files are FINE.
+22. `conductor/directives/no_new_src_files_without_permission/v1.md` — source: `AGENTS.md:68-76`. Content: the audit trigger — "is `<thing>` a new system, or is it part of an existing system?" If it's part of an existing system, the file goes in that system's file.
+23. `conductor/directives/large_files_are_fine/v1.md` — source: `AGENTS.md:62-67`. Content: large files are FINE. The "small files are good" stance is propaganda from LLM training data. Cognitive load is managed via naming, regions, and navigation tools — NOT via file splitting.
+
+- [ ] **Step 1.7: Harvest process/workflow directives (10 directives)**
+
+**Files to read:**
+- `conductor/workflow.md:80-120` (Standard Task Workflow — TDD, atomic commits, delegate)
+- `conductor/workflow.md:112-170` (Phase Completion Verification + API Hooks verification)
+- `conductor/workflow.md:262-280` (Structural Testing Contract)
+- `AGENTS.md:49-85` (Critical Anti-Patterns)
+- `AGENTS.md:86-118` (Session-Learned Anti-Patterns)
+- `AGENTS.md:119-185` (Process Anti-Patterns)
+- `conductor/workflow.md:385-391` (Tier 2 conventions — the 2 new rules)
+
+**Directives to create:**
+
+24. `conductor/directives/atomic_per_task_commits/v1.md` — source: `workflow.md:112` + `AGENTS.md:55`. Content: commit per-task for atomic rollback. Do NOT batch commits.
+25. `conductor/directives/tdd_red_green_required/v1.md` — source: `workflow.md:78-100` (Standard Task Workflow steps 4-6). Content: write failing tests before implementing. Run tests, confirm they fail (Red). Implement, run, confirm pass (Green). The Zero-Assertion Ban (tests must have meaningful assertions).
+26. `conductor/directives/ban_arbitrary_core_mocking/v1.md` — source: `workflow.md:262`. Content: ban on `unittest.mock.patch` to bypass core infrastructure unless explicitly authorized.
+27. `conductor/directives/live_gui_poll_not_sleep/v1.md` — source: `workflow.md:465-475` (Anti-Pattern: push_event + time.sleep + assert). Content: replace `time.sleep(N)` with a poll loop on `get_value` or `wait_for_event`.
+28. `conductor/directives/batch_verification_not_isolation/v1.md` — source: `workflow.md:510-514` (Isolated-Pass Verification Fallacy). Content: the only verification that matters for `live_gui` tests is the batch run. Do NOT commit a fix verified only in isolation.
+29. `conductor/directives/git_hard_bans/v1.md` — source: `AGENTS.md:59` + `workflow.md:417-430`. Content: `git restore`, `git checkout -- <file>`, `git reset` are FORBIDDEN without explicit user permission. Use `git show` for inspection, not `git checkout`.
+30. `conductor/directives/ban_day_estimates/v1.md` — source: `AGENTS.md:60`. Content: no day/hour/minute estimates in track artifacts. Measure effort by scope (N files, M sites, N tasks).
+31. `conductor/directives/no_output_filtering/v1.md` — source: `workflow.md:386`. Content: NEVER filter test output through `Select-Object`, `head`, `tail`. Always redirect to a log file.
+32. `conductor/directives/prefer_targeted_tier_runs/v1.md` — source: `workflow.md:387`. Content: do NOT run the full 11-tier batch for every verification. Run targeted tiers.
+33. `conductor/directives/mandatory_research_first/v1.md` — source: `workflow.md:46`. Content: before reading any file >50 lines, use `get_file_summary`/`py_get_skeleton`/`py_get_code_outline` to map the structure first.
+
+- [ ] **Step 1.8: Harvest process anti-patterns (6 directives)**
+
+**Files to read:**
+- `AGENTS.md:119-185` (Process Anti-Patterns — the 8 named patterns)
+- `conductor/workflow.md` "Skip-Marker Policy" section
+
+**Directives to create:**
+
+34. `conductor/directives/no_skip_markers_as_avoidance/v1.md` — source: `workflow.md` "Skip-Marker Policy" + `AGENTS.md:54`. Content: `@pytest.mark.skip` is documentation of a known failure, not an escape from fixing the bug. Fix in-session when feasible.
+35. `conductor/directives/deduction_loop_limit/v1.md` — source: `AGENTS.md:127` (Process Anti-Pattern #1). Content: at most 2 test runs in a single investigation. After the 2nd failure, STOP and read the code.
+36. `conductor/directives/report_instead_of_fix_ban/v1.md` — source: `AGENTS.md:134` (Process Anti-Pattern #2). Content: a 200-line status report is a confession, not a fix. A good status report is 5-10 sentences.
+37. `conductor/directives/scope_creep_track_doc_ban/v1.md` — source: `AGENTS.md:143` (Process Anti-Pattern #3). Content: if the user asks for a fix, your output is the fix. A track doc is only for multi-day work.
+38. `conductor/directives/inherited_cruft_ask_first/v1.md` — source: `AGENTS.md:149` (Process Anti-Pattern #4). Content: if a file is broken from a previous session, ASK the user before trying to fix it.
+39. `conductor/directives/verbose_commit_message_ban/v1.md` — source: `AGENTS.md:176` (Process Anti-Pattern #7). Content: a commit message is 1-3 sentences. If it's longer than 15 lines, it's a report.
+
+- [ ] **Step 1.9: Harvest GUI/architecture directives (5 directives)**
+
+**Files to read:**
+- `conductor/product-guidelines.md:29-43` (UX & UI Principles + Code Standards)
+- `conductor/workflow.md:39` (ImGui Verification)
+
+**Directives to create:**
+
+40. `conductor/directives/imgui_scope_verification/v1.md` — source: `product-guidelines.md:39` + `workflow.md:39`. Content: all changes to `gui_2.py` MUST be verified using `scripts/check_imgui_scopes.py`. Use `imscope` context managers over manual push/pop.
+41. `conductor/directives/modular_controller_pattern/v1.md` — source: `product-guidelines.md:40`. Content: state-independent logic must be moved to module-level functions. Massive `if/elif` dispatch blocks must be refactored into handler maps.
+42. `conductor/directives/ui_delegation_for_hot_reload/v1.md` — source: `product-guidelines.md:41`. Content: all complex ImGui rendering logic must be extracted from the `App` class into module-level `render_xxx(app)` functions. The `App` class should only contain thin delegation wrappers.
+43. `conductor/directives/strict_state_management/v1.md` — source: `product-guidelines.md:37`. Content: rigorous separation between the Main GUI rendering thread and daemon execution threads. The UI should NEVER hang during AI communication. Use lock-protected queues and events.
+44. `conductor/directives/comprehensive_logging/v1.md` — source: `product-guidelines.md:38`. Content: aggressively log all actions, API payloads, tool calls, and executed scripts. Maintain timestamped JSON-L and markdown logs.
+
+- [ ] **Step 1.10: Harvest feature-flag + RAG + cache + knowledge directives (4 directives)**
+
+**Files to read:**
+- `conductor/code_styleguides/feature_flags.md`
+- `conductor/code_styleguides/rag_integration_discipline.md:11-20` (the 6 rules)
+- `conductor/code_styleguides/cache_friendly_context.md:52-74` (the byte-comparison test)
+- `conductor/code_styleguides/knowledge_artifacts.md`
+
+**Directives to create:**
+
+45. `conductor/directives/feature_flag_delete_to_turn_off/v1.md` — source: `feature_flags.md`. Content: file presence ("delete to turn off") for side artifacts; config flags for persistent preferences; CLI flags for one-shot overrides.
+46. `conductor/directives/rag_six_rules/v1.md` — source: `rag_integration_discipline.md:11-20`. Content: the 6 rules (opt-in, complements, provenance, no mutation, feature-gated, graceful failure).
+47. `conductor/directives/cache_stable_to_volatile/v1.md` — source: `cache_friendly_context.md:52-74`. Content: stable-to-volatile context ordering. The byte-comparison test. Layers 1-7 cacheable, 8-12 not.
+48. `conductor/directives/knowledge_harvest_pattern/v1.md` — source: `knowledge_artifacts.md`. Content: the category files + provenance + sha256 ledger + digest regeneration pattern.
+
+- [ ] **Step 1.11: Commit the directive harvest**
+
+```bash
+git add conductor/directives/
+git commit -m "feat(directives): harvest 48 directives from doc tree into conductor/directives/
+
+Systematic extraction of every directive-like statement (imperative,
+preference, hard ban, convention, anti-pattern) from the entire doc tree
+into conductor/directives/<name>/v1.md files. Each v1 is a verbatim lift
+from the source doc with a header annotating the source location.
+
+Sources combed: AGENTS.md, conductor/workflow.md, conductor/product-guidelines.md,
+conductor/tech-stack.md, all 10 conductor/code_styleguides/*.md, docs/AGENTS.md.
+
+Original docs remain untouched as canonical source. The conductor/directives/
+tree is a parallel structure, not a replacement."
+```
+
+---
+
+## Phase 2: Baseline Preset + Role-Prompt Bootstrap
+
+Focus: Create the `current_baseline.md` preset that lists all 48 directives, then update the 5 role prompts with the `warm with:` bootstrap.
+
+- [ ] **Step 2.1: Create the baseline preset**
+
+**File:** `conductor/directives/presets/current_baseline.md`
+
+**Content:**
+
+```markdown
+# Preset: current_baseline
+
+The baseline directive composition — all v1 variants lifted verbatim from the
+current production docs. This is the starting point; alternative presets swap
+variants to test different encodings.

+## Notes
+
+All v1 (verbatim lifts from current production docs). No alternative encodings
+tested yet. This preset is the control group for future experiments.
+
+To create an experimental preset: copy this file, change the variant path for
+the directives you want to test (e.g., swap `v1.md` for `v2_rationale_first.md`),
+and update the Notes section with your hypothesis.
+```
+
+- [ ] **Step 2.2: Commit the preset**
+
+```bash
+git add conductor/directives/presets/current_baseline.md
+git commit -m "feat(directives): add current_baseline preset (48 directives, all v1)"
+```
+
+- [ ] **Step 2.3: Update tier1-orchestrator.md with warm with: bootstrap**
+
+**File:** `.opencode/agents/tier1-orchestrator.md`
+
+**What to change:** Find the "MANDATORY: Pre-Action Required Reading" section (or equivalent hardcoded file list). Replace the directive-reading portion with:
+
+```markdown
+## MANDATORY: Directive Warm-up
+
+warm with: conductor/directives/presets/current_baseline.md
+
+Read the preset file above. It lists directive variant files to read before any action.
+Read each file the preset references. These are your active directives for this session.
+
+If the user specifies a different preset (e.g., "warm with: conductor/directives/presets/exploratory_rationale.md"),
+use that instead. The user's instruction overrides the default.
+```
+
+**What stays (non-directive reads that remain hardcoded):**
+- `AGENTS.md` — project operating rules
+- `conductor/workflow.md` — operational workflow
+- `conductor/edit_workflow.md` — edit tool contract
+- The relevant `docs/guide_*.md` — architecture reference
+
+- [ ] **Step 2.4: Update tier2-tech-lead.md with warm with: bootstrap**
+
+**File:** `.opencode/agents/tier2-tech-lead.md`
+
+Same change as Step 2.3. The non-directive reads that stay hardcoded:
+- `AGENTS.md`
+- `conductor/workflow.md`
+- `conductor/edit_workflow.md`
+- `conductor/tier2/githooks/forbidden-files.txt`
+- The relevant `docs/guide_*.md`
+
+- [ ] **Step 2.5: Update tier3-worker.md with warm with: bootstrap**
+
+**File:** `.opencode/agents/tier3-worker.md`
+
+Same change. Note: Tier 3 may benefit from a reduced preset (fewer directives — they don't need the planning/strategy directives). But for now, use `current_baseline.md` and let the user create a `worker_minimal.md` preset later.
+
+- [ ] **Step 2.6: Update tier4-qa.md with warm with: bootstrap**
+
+**File:** `.opencode/agents/tier4-qa.md`
+
+Same change. Tier 4 reads narrowly; the preset can be customized later.
+
+- [ ] **Step 2.7: Update tier2-autonomous.md with warm with: bootstrap**
+
+**File:** `conductor/tier2/agents/tier2-autonomous.md`
+
+This file has the most extensive hardcoded reading list (11 files, lines 32-52). Replace the directive-reading portion with the `warm with:` bootstrap. The non-directive reads that stay:
+- `AGENTS.md`
+- `conductor/workflow.md`
+- `conductor/edit_workflow.md`
+- `conductor/tier2/githooks/forbidden-files.txt`
+- `conductor/tracks/tier2_leak_prevention_20260620/spec.md` (this is a track spec, not a directive — stays hardcoded)
+
+- [ ] **Step 2.8: Commit the role-prompt updates**
+
+```bash
+git add .opencode/agents/tier1-orchestrator.md .opencode/agents/tier2-tech-lead.md .opencode/agents/tier3-worker.md .opencode/agents/tier4-qa.md conductor/tier2/agents/tier2-autonomous.md
+git commit -m "feat(role-prompts): replace hardcoded directive lists with warm with: bootstrap
+
+All 5 tier role prompts now use 'warm with: conductor/directives/presets/current_baseline.md'
+instead of a hardcoded list of ~11 files. The LLM reads the preset, then reads
+the variant files it lists. Non-directive reads (AGENTS.md, workflow.md,
+edit_workflow.md, forbidden-files.txt, guide_*.md) remain hardcoded.
+
+The user can override the preset per-session by saying 'warm with: <path>' in
+their session message. This is the hot-swap mechanism."
+```
+
+---
+
+## Phase 3: Verification + End-of-Track
+
+- [ ] **Step 3.1: Verify the directory structure**
+
+```bash
+# Count directive directories
+ls conductor/directives/ | wc -l
+
+# Count v1.md files
+find conductor/directives/ -name "v1.md" | wc -l
+
+# Verify preset exists
+test -f conductor/directives/presets/current_baseline.md
+
+# Verify all 5 role prompts have the warm with: line
+grep -l "warm with:" .opencode/agents/tier1-orchestrator.md .opencode/agents/tier2-tech-lead.md .opencode/agents/tier3-worker.md .opencode/agents/tier4-qa.md conductor/tier2/agents/tier2-autonomous.md
+```
+
+Expected: 48 directive directories, 48 v1.md files, preset exists, 5 role prompts have `warm with:`.
+
+- [ ] **Step 3.2: Manual verification — does the LLM follow the warm with: instruction?**
+
+Start a new OpenCode session with any tier role. Observe whether the LLM:
+1. Reads the preset file at `conductor/directives/presets/current_baseline.md`
+2. Reads each variant file listed in the preset
+3. Has the directives in context for the session
+
+This is the "test" — there's no automated test for this. The signal is: does the LLM behave as if it has read the directives?
+
+- [ ] **Step 3.3: Write end-of-track report**
+
+**File:** `docs/reports/TRACK_COMPLETION_directive_hotswap_harness_20260627.md`
+
+Document:
+- What shipped (48 directives + baseline preset + 5 role-prompt updates)
+- The directory structure
+- The preset format
+- The `warm with:` bootstrap
+- How to hot-swap (create a new preset or tell the LLM "warm with: <path>")
+- What's NOT included (no scripts, no TOML, no v2+ variants yet)
+- Handoff to future tracks (alternative encoding authoring, Manual Slop integration, token-cost analysis)
+
+- [ ] **Step 3.4: Commit the end-of-track report**
+
+```bash
+git add docs/reports/TRACK_COMPLETION_directive_hotswap_harness_20260627.md

+# Design: Directive Hot-Swap Harness (OpenCode Directive Presets)
+
+**Date:** 2026-06-27
+**Status:** Draft — pending user review
+**Track ID (proposed):** `directive_hotswap_harness_20260627`
+
+## Problem
+
+The codebase's directives — the instructions that tell LLMs how to behave (banned patterns, conventions, hard bans, anti-patterns) — are scattered across the entire doc tree: `AGENTS.md`, `conductor/workflow.md`, `conductor/product-guidelines.md`, `conductor/tech-stack.md`, every `conductor/code_styleguides/*.md`, `docs/Readme.md`, `docs/AGENTS.md`, all 14 `docs/guide_*.md`, etc. They're embedded in prose, tables, anti-pattern sections, "Critical Anti-Patterns" lists, "Hard Rules," styleguide sections.
+
+The 4 tier role prompts (`.opencode/agents/tier1-orchestrator.md`, `tier2-tech-lead.md`, `tier3-worker.md`, `tier4-qa.md`) plus the autonomous variant (`conductor/tier2/agents/tier2-autonomous.md`) currently hardcode a list of ~11 files to read before any action. This list is static — every session gets the same directives regardless of the task. There's no mechanism to:
+- Test whether an alternative encoding of the same directive (imperative-ban vs. rationale-first vs. before/after) produces better LLM compliance
+- Hot-swap which encoding is active without manually editing files or navigating the filesystem
+- Exercise per-session control over which directives the LLM warms up with
+
+## Goal
+
+Build a **directive hot-swap harness** that lets the user:
+1. Maintain multiple alternative encodings ("variants") of the same directive as separate files
+2. Compose active directive sets into named "presets" (markdown bills of materials)
+3. Hot-swap which preset is active via a single `warm with: <path>` instruction in the role prompt or session message
+4. Use the existing file-reading behavior LLMs already have — no scripts, no TOML, no build steps
+
+## Design
+
+### The directive directory structure
+
+```
+conductor/directives/
+  <directive_name>/
+    v1.md          ← the baseline encoding (verbatim lift from current docs)
+    v2_<style>.md  ← alternative encodings (added over time)
+  presets/
+    current_baseline.md    ← the default preset (all v1)
+    <experimental>.md      ← alternative presets (added over time)
+```
+
+**Naming convention:** lowercase, underscore-separated, action-oriented (`ban_dict_any`, not `dict_str_any_ban`). The name describes the directive's intent.
+
+**Variant file format:** each `vN.md` has a short header annotating why this iteration exists, then the directive text:
+
+```markdown
+# <directive_name> — v1
+
+**Why this iteration:** Lifted verbatim from `conductor/code_styleguides/python.md` §17.1.
+This is the baseline encoding — the imperative-ban style currently in production.
+Future variants will test alternative encodings against this baseline.
+
+---
+
+<directive text>
+```
+
+### The preset format
+
+A preset is a markdown bill of materials. It tells the LLM which directive variant files to read for this run. Nothing more.
+
+```markdown
+# Preset: current_baseline
+
+The baseline directive composition — all v1 variants lifted from the current
+production docs.
+

+
+All v1 (verbatim lifts from current production docs). No alternative encodings
+tested yet. This preset is the control group for future experiments.
+```
+
+**Key properties:**
+- **Flat list.** No nesting, no conditionals, no includes. The LLM reads the list, reads the files.
+- **Human-readable name.** `current_baseline`, `exploratory_rationale`, `minimal_tokens` — pick by name.
+- **Notes section.** Documents the hypothesis being tested. This is the experiment log, inline with the preset.
+- **Partial swaps.** Swap 2-3 directives to v2, leave the rest at v1. The preset makes the diff explicit.
+- **No script needed.** Author a new preset by copying an existing one and changing variant paths. Hot-swap by telling the LLM which preset to use.
+
+### The role-prompt bootstrap
+
+The 5 role prompts (`.opencode/agents/tier1-orchestrator.md`, `tier2-tech-lead.md`, `tier3-worker.md`, `tier4-qa.md`, and `conductor/tier2/agents/tier2-autonomous.md`) have a hardcoded "MANDATORY: Pre-Action Required Reading" section listing ~11 specific files. This is replaced with a single `warm with:` directive.
+
+```markdown
+## MANDATORY: Directive Warm-up
+
+warm with: conductor/directives/presets/current_baseline.md
+
+Read the preset file above. It lists directive variant files to read before any action.
+Read each file the preset references. These are your active directives for this session.
+
+If the user specifies a different preset (e.g., "warm with: conductor/directives/presets/exploratory_rationale.md"),
+use that instead. The user's instruction overrides the default.
+```
+
+**Key properties:**
+- **One line is the bootstrap.** `warm with: <path>` is the entire mechanism.
+- **User override.** The user can tell the LLM "warm with: <path>" in their session message and it uses that preset instead of the default. This is the hot-swap — no file editing, just a text instruction.
+- **Per-role defaults.** Each tier role prompt can default to a different preset.
+- **Non-directive reads remain hardcoded.** Files that aren't tunable directives (e.g., `conductor/tracks/tier2_leak_prevention_20260620/spec.md`, `conductor/tier2/githooks/forbidden-files.txt`) stay as direct references in the role prompt.
+
+### What stays in the role prompt (not directive-based)
+
+- `AGENTS.md` — project operating rules (contains directives AND non-directive rules)
+- `conductor/workflow.md` — operational workflow
+- `conductor/edit_workflow.md` — edit tool contract
+- `conductor/tier2/githooks/forbidden-files.txt` — file denylist
+- The relevant `docs/guide_*.md` — architecture reference
+
+These are context, not tunable directives. They stay hardcoded in the role prompt.
+
+### The directive harvest
+
+The directives are NOT limited to the 11 files the role prompts mandate. They're scattered across the entire doc tree. The track's first phase is a systematic harvest:
+
+**A directive is any statement that tells the LLM:**
+- "Do X" / "Don't do X" (imperative)
+- "Use Y instead of Z" (preference)
+- "This is BANNED" (hard ban)
+- "Follow pattern P" (convention)
+- "Never do Q" (anti-pattern)
+
+**NOT a directive:**
+- Descriptive prose ("The App class holds GUI state")
+- Architecture documentation ("Thread domains are separated by...")
+- Reference material ("The 45-tool inventory includes...")
+
+**Sources to comb (non-exhaustive):**
+- `AGENTS.md` — "Critical Anti-Patterns", "File Size and Naming Convention", "Session-Learned Anti-Patterns", "Process Anti-Patterns"
+- `conductor/workflow.md` — "Code Style", "Guiding Principles", "Testing Requirements", "Known Pitfalls", "Process Anti-Patterns", "Tier 2 Autonomous Sandbox conventions"
+- `conductor/product-guidelines.md` — "Core Value", "Code Standards & Architecture", "Data-Oriented Error Handling", "Phase 5: Heavy Curation"
+- `conductor/tech-stack.md` — "Core Value" header
+- `conductor/code_styleguides/data_oriented_design.md` — §8.5 "Python Type Promotion Mandate", the 7-question simplification pass, the 10-question self-check
+- `conductor/code_styleguides/python.md` — §10 "Anti-OOP Conventions", §17 "LLM Default Anti-Patterns" (the 7 banned patterns)
+- `conductor/code_styleguides/error_handling.md` — the Result[T] convention, the AI Agent Checklist
+- `conductor/code_styleguides/type_aliases.md` — "When NOT to promote"
+- `conductor/code_styleguides/feature_flags.md` — "delete to turn off" convention
+- `conductor/code_styleguides/agent_memory_dimensions.md` — the 4-dimension decision tree
+- `conductor/code_styleguides/rag_integration_discipline.md` — "conservative-RAG rule"
+- `conductor/code_styleguides/cache_friendly_context.md` — stable-to-volatile ordering
+- `conductor/code_styleguides/knowledge_artifacts.md` — the harvest pattern
+- `docs/AGENTS.md` — "Convention Enforcement"
+- `docs/Readme.md` — any directive-like content in feature descriptions
+
+**Granularity resolution:** the harvest produces a candidate list. Then the question of which directives to merge (e.g., `ban_prefix_aliasing` + `no_local_imports` might become `import_hygiene`), split, or keep standalone is resolved in the harvest phase — not locked in upfront.
+
+### The original docs stay untouched
+
+The `conductor/directives/` tree is a *parallel* structure, not a replacement. The original docs (`python.md`, `error_handling.md`, `AGENTS.md`, etc.) remain the canonical source until a future track deprecates them. The harness is useful immediately (the v1 variants are exact copies); the old docs are not broken.
+
+### Why no scripts / TOML
+
+The user explicitly rejected TOML manifests and scripts for this initial version: "no need to systematize that hard when I don't know what's going to work yet." The preset is markdown. The hot-swap is a text instruction. The variant selection is a path in a markdown file. No build steps, no generated files, no tooling dependencies. If the system proves useful, a future track can add automation (auto-generating presets from the directory tree, token-cost analysis per variant, automated compliance testing).
+
+## Scope: Two Parallel Campaigns
+
+The user's request bundles two distinct campaigns that share a theme ("how do you encode information densely for an LLM?") but are tracked and executed independently.
+
+### Campaign A: Directive Hot-Swap Harness (this spec)
+
+**Track A-1 (this):** directive harvest + scaffold + baseline preset + role-prompt bootstrap update. Gets the system working with v1 (current) encodings.
+
+Future tracks in Campaign A:
+- Alternative encoding authoring (v2, v3 per directive — the actual experimentation)
+- Manual Slop integration (a "Directive Lab" panel for virtualized directive selection)
+- Token-cost analysis tooling
+- Automated compliance testing
+
+### Campaign B: Video Analysis (4 new videos)
+
+A separate research campaign following the established 3-pass pattern from the previous 12-video campaign (Pass 1: extract → Pass 2: deobfuscate → Pass 3: project to C11/Python). The 4 videos:
+
+1. **Reinventing Entropy | Compression is Intelligence Part 1** (https://youtu.be/l6DKRf-fAAM)
+2. **Yann LeCun: World Models: Enabling the next AI revolution** (https://www.youtube.com/watch?v=72Xj8k5WQX4)
+3. **Yann LeCun's $1B Bet Against LLMs [Part 1]** (https://youtu.be/kYkIdXwW2AE)
+4. **Recursive Self-Improvement** (https://youtu.be/t7_ZXgfJVG8)
+
+### Cross-Campaign Relationship
+
+The two campaigns inform each other but have no hard dependency:
+
+- **The video analysis informs directive encoding.** The entropy/compression video (video 1) provides theoretical grounding for how information density affects comprehension. LeCun's world-model work (videos 2-3) informs how LLMs model directive intent. Recursive self-improvement (video 4) is directly relevant to the meta-question of whether better directive encodings can be discovered iteratively. Insights from the video analysis may surface alternative encoding strategies to test in Campaign A's harness.
+
+- **The harness informs the video analysis.** The previous video campaign produced a lexicon + C11 reference + deobfuscation DSL. The directive harness is itself a compression-aid tool — it encodes the same directive in fewer/different tokens and observes the effect. The harness's design (preset as bill-of-materials, variant as alternative encoding) is the same pattern as the video campaign's deobfuscation pass (same content, different encoding). The harness may inform how the video analysis encodes its own outputs.
+
+- **Execution order:** the campaigns can run in parallel. Campaign A (Track A-1) is an engineering track; Campaign B is a research track. They don't share files. The cross-pollination is intellectual, not structural.
+
+### The video analysis track structure (Campaign B)
+
+Follows the established 3-pass pattern from `docs/reports/2026-06-15/CAMPAIGN_CLOSE_OUT_video_analysis_20260621.md`:
+
+- **Pass 1:** Information extraction (4 deep-dive reports, one per video). Uses the existing `scripts/video_analysis/` pipeline (download_video, extract_transcript, extract_keyframes, ocr_frames, synthesize_report). The lexicon v2 from the previous campaign is the starting point for deobfuscation.
+- **Pass 2:** Deobfuscation (apply the lexicon v2 to the 4 new videos' content). May produce lexicon v3 corrections if the new videos surface notation the lexicon doesn't cover.
+- **Pass 3:** C11/Python projection (project each video's deobfuscated content to code in the user's idiomatic style).
+
+The video analysis track is initialized as a separate conductor track (`video_analysis_campaign_2_20260627` or similar). Its spec/plan is authored separately from this design doc.
+
+## Out of Scope (for Track A-1)
+
+- **Authoring alternative encodings (v2+).** This track only creates v1 (verbatim lifts). The experimentation is a future activity.
+- **Deprecating the original docs.** The old docs stay as canonical source.
+- **Scripts for preset generation or variant selection.** No automation in this version.
+- **Manual Slop GUI integration.** The harness is OpenCode-only for now.
+- **Token-cost analysis.** No tooling to measure token cost per variant in this version.
+- **Automated compliance testing.** No test harness to measure LLM compliance per encoding.
+- **The 4-video analysis (Campaign B).** Separate track, separate campaign. This design doc covers Campaign A (the harness) only. The video analysis gets its own track spec.
+
+## Risks
+
+1. **Harvest completeness.** The directive harvest might miss directives embedded in prose. Mitigation: systematic combing of the doc tree + the user reviews the candidate list before variants are created.
+2. **Granularity ambiguity.** Some directives overlap (e.g., "ban dict[str, Any]" and "use typed dataclass fields" are two sides of the same coin). Mitigation: the harvest phase produces a candidate list; the granularity is resolved there, not upfront.
+3. **Role-prompt drift.** The 5 role prompts need to be updated consistently. Mitigation: the `warm with:` line is the only change; the rest of each role prompt is untouched.
+4. **Adoption friction.** LLMs might not follow the `warm with:` instruction reliably. Mitigation: the instruction is simple (read a file, read the files it lists) and uses the existing file-reading behavior the LLMs already have.

+Focus: Implement `scripts/audit_boundary_layer.py` + `scripts/boundary_layer_allowlist.toml` + tests, mirroring the `audit_imports.py` + `audit_imports_whitelist.toml` contract.
+
+- [ ] Task 1.1: Write failing tests for `scripts/audit_boundary_layer.py`
+  - **WHERE:** `tests/test_audit_boundary_layer.py` (NEW file)
+  - **WHAT:** 10 tests per spec FR5 (finder detects `dict[str, Any]` in return / param / local; allowlist suppression + WHITELISTED annotation; `--strict` exit 1 on un-allowlisted; `--strict` exit 0 on allowlisted; `--json` shape; missing-file handling; syntax-error handling; `--show-allowlist`).
+  - **HOW:** Use `tmp_path` (or `tests/artifacts/` per workspace_paths.md — see workflow.md "Test Sandbox Hardening") to create a synthetic `src/` tree the audit can scan via a `--src` flag (mirror `audit_weak_types.py --src`). Each test creates 1-2 small .py files with the pattern under test, invokes the audit via `subprocess.run(["python", "scripts/audit_boundary_layer.py", "--src", str(tmp_src), ...])`, asserts on stdout + exit code. Tests MUST fail before the script exists (Red phase).
+  - **SAFETY:** No `live_gui` fixture (these are unit tests of a script). No `unittest.mock.patch` of core code. Use `monkeypatch.setenv` for the `--src` path or pass via argv.
+  - **COMMIT:** `test(audit): add 10 failing tests for boundary-layer audit`
+  - **GIT NOTE:** Red-phase tests for `scripts/audit_boundary_layer.py`; cover finder + allowlist + strict + json + error-handling per spec FR1 + FR5.
+
+- [ ] Task 1.2: Implement `scripts/audit_boundary_layer.py`
+  - **WHERE:** `scripts/audit_boundary_layer.py` (NEW file)
+  - **WHAT:** Implement the audit per spec FR1. The structure mirrors `scripts/audit_imports.py` (309 lines): module docstring → argparse → `audit_file(path) -> list[Finding]` → main loop over `sorted(Path(src).glob("*.py"))` → exit code logic.
+  - **HOW:** Reuse the `audit_optional_in_3_files.py` AST detector pattern (it already has `_annotation_is_optional_arg` — copy the analogous `_is_dict_str_any` helper). Detection contract (FR1):
+    1. Walk each `ast.FunctionDef` / `AsyncFunctionDef`:
+       - If `node.returns` is `dict[str, Any]` (Subscript with value Name "dict"|"Dict" and slice Tuple `[Name "str", Name "Any"]`) → emit `RETURN_DICT_ANY`.
+       - For each arg in `args.args + kwonlyargs + posonlyargs`: if `arg.annotation` is `dict[str, Any]` → emit `PARAM_DICT_ANY`.
+    2. Walk each `ast.AnnAssign` inside a function body: if `target.annotation` is `dict[str, Any]` → emit `LOCAL_ANNOT_DICT_ANY`.
+    3. Allowlist: load `scripts/boundary_layer_allowlist.toml` (use `tomllib.load`); for any file whose relative path is a key, suppress all findings for that file and emit a single `WHITELISTED` finding per file (matches `audit_imports.py` precedent).
+    4. CLI flags: `--strict`, `--json`, `--show-allowlist`, `--no-allowlist`, `--src <path>` (default `"src"`).
+    5. Default mode: print summary table (file, sites, allowlisted) + a list of violations; exit 0.
+    6. `--strict`: same + exit 1 if there are un-allowlisted `RETURN_DICT_ANY` / `PARAM_DICT_ANY` / `LOCAL_ANNOT_DICT_ANY` findings.
+    7. `--json`: print JSON `{files_scanned, files_with_findings, total_findings, by_kind, findings}` and exit 0.
+    8. `--show-allowlist`: print the TOML contents + reasons; exit 0.
+    9. `--no-allowlist`: do not read the TOML; audit all sites.
+  - **SAFETY:** Pure stdlib (`ast`, `argparse`, `json`, `sys`, `pathlib.Path`, `tomllib`). No subprocess to `src/` files.
+  - **COMMIT:** `feat(audit): implement audit_boundary_layer.py per FR1`
+  - **GIT NOTE:** Implements the §17.7 boundary-layer audit; mirrors audit_imports.py contract; allowlist-driven per-file suppression.
+
+- [ ] Task 1.3: Write `scripts/boundary_layer_allowlist.toml`
+  - **WHERE:** `scripts/boundary_layer_allowlist.toml` (NEW file)
+  - **WHAT:** Initial allowlist with the ~14 legitimate boundary files from spec "Current State Audit": `context_presets.py`, `events.py`, `openai_compatible.py`, `theme_models.py`, `log_registry.py`, `presets.py`, `tool_presets.py`, `personas.py`, `workspace_manager.py`, `paths.py`, `gemini_cli_adapter.py`, `mcp_client.py`, `type_aliases.py`, `session_logger.py`.
+  - **HOW:** Mirror `audit_imports_whitelist.toml` format:
+    - Header comment block (purpose + format).
+    - "Last reviewed: 2026-06-27"
+    - One `[allowlist."<relative_path>"]` entry per file with `reason = "..."` documenting why it's at the wire boundary (the reasons are documented in spec "Current State Audit" — e.g., context_presets = "project_dict is the wire TOML"; events.to_dict = "wire serialization for WS protocol"; etc.).
+  - **SAFETY:** Pure TOML; no code.
+  - **COMMIT:** `feat(audit): seed boundary_layer_allowlist.toml with 14 boundary files`
+  - **GIT NOTE:** Allowlist seeds the §17.7 legitimate boundary; per audit_imports_whitelist.toml precedent.
+
+- [ ] Task 1.4: Run tests for Phase 1 (Green phase)
+  - **WHAT:** Execute `uv run pytest tests/test_audit_boundary_layer.py -v` (batched-runner convention can also be used: `uv run python scripts/run_tests_batched.py --filter test_audit_boundary_layer`). All 10 tests must pass. If any fail, debug (≤2 retries per workflow.md "Deduction Loop" rule), then STOP and report if still failing.
+  - **COMMIT:** `conductor(state): mark Phase 1 task 1.4 verification` (or skip the commit if no code changes; just verify).
+  - **GIT NOTE:** Green-phase verification for boundary-layer audit + allowlist.
+
+---
+
+## Phase 2: Optional[T] Audit Rename + Widening
+
+Focus: Rename `audit_optional_in_3_files.py` → `audit_optional_returns.py`, widen from 4 files to all `src/*.py`, baseline the 3 `history.py` residuals.
+
+- [ ] Task 2.1: Write failing tests for the renamed + widened audit
+  - **WHERE:** `tests/test_audit_optional_returns.py` (NEW file)
+  - **WHAT:** 5 tests per spec FR5: test_renamed_script_exists, test_scans_all_src_files, test_baseline_reading_keeps_strict_green, test_strict_exits_1_above_baseline, test_param_optional_is_warning_not_strict.
+  - **HOW:** For test_scans_all_src_files, use `monkeypatch` + `--src <tmp_src>` flag (the script may need a `--src` flag added in Task 2.2 if it doesn't already have one — current `audit_optional_in_3_files.py` hardcodes the 4-file path; Task 2.2 adds `--src`). Tests must fail against the OLD script (which still hardcodes 4 files).
+  - **SAFETY:** No `live_gui`. No core mocking.
+  - **COMMIT:** `test(audit): add 5 failing tests for audit_optional_returns widening`
+  - **GIT NOTE:** Red-phase tests for the rename + widening to all src/*.py per spec FR3 + FR5.
+
+- [ ] Task 2.2: Rename + widen `audit_optional_in_3_files.py` → `audit_optional_returns.py`
+  - **WHERE:** `git mv scripts/audit_optional_in_3_files.py scripts/audit_optional_returns.py` then edit the new file.
+  - **WHAT:** Per spec FR3:
+    1. `git mv` the file (preserves history).
+    2. Edit `scripts/audit_optional_returns.py`:
+       - Module docstring: drop "4 baseline files"; say "all `src/*.py` per §17 post-2026-06-27 widening (the successor to `audit_optional_in_3_files.py`, which was renamed + widened on 2026-06-27)."
+       - Replace `BASELINE_FILES: tuple[str, ...] = (...)` with `def _discover_src_files(src_dir: str = "src") -> list[Path]: return sorted(Path(src_dir).glob("*.py"))`.
+       - Update `main()` to iterate `_discover_src_files(args.src)` instead of the hardcoded tuple.
+       - Add `--src <path>` arg (default `"src"`) mirroring `audit_weak_types.py`.
+       - Update `--json` output's `"files_scanned"` field to reflect the glob count.
+    3. Create `scripts/audit_optional_returns.baseline.json` recording the 3 `src/history.py` `RETURN_OPTIONAL` findings so `--strict` exits 0 on master (findings ≤ baseline). Format: same as `audit_weak_types.baseline.json` (a JSON object with a count or a list of `{file, line, function, kind}` entries that strict mode subtracts). The strict-mode logic: load baseline; subtract baseline findings from current findings; exit 1 if residuals > 0. (Mirror `audit_weak_types.py`'s `--strict` + baseline contract — read its source to confirm the exact subtraction mechanism.)
+  - **SAFETY:** No `src/` edits. No tests/ edits except the new test file from Task 2.1.
+  - **COMMIT:** `refactor(audit): rename audit_optional_in_3_files.py -> audit_optional_returns.py; widen to all src/*.py; baseline 3 history.py residuals`
+  - **GIT NOTE:** Closes contradictions C1+C21 (script name) + C2 (Optional ban scope ambiguity); script name + scope + baseline now honest per §17 post-2026-06-27.
+
+- [ ] Task 2.3: Run tests for Phase 2 (Green phase)
+  - **WHAT:** `uv run pytest tests/test_audit_optional_returns.py -v`. All 5 tests must pass. If failures, ≤2 debug retries; then STOP.
+  - **VERIFY:** Also run the existing audit_optional tests (if any reference the old name, update them — likely there are no callers other than `code_path_audit_20260607`'s historical references which don't run).
+  - **COMMIT:** `conductor(state): mark Phase 2 task 2.3 verification` (or skip if no code changes).
+  - **GIT NOTE:** Green-phase verification for the rename + widening.
+
+---
+
+## Phase 3: Styleguide Doc Reconciliation
+
+Focus: Fix `python.md` §17 enforcement inventory + §17.8 section to match post-track reality. Close contradictions C3, C18 (audit_imports exists), C1+C21 (script renamed), C2 (scope clarified), C5 (Result notation — only if no branch-sensitivity; per spec OOS, this is C5 which is deferred — confirm during this phase).
+
+- [ ] Task 3.1: Fix `python.md` §17 inventory table (lines 449-456) + §17.8 enforcement section (lines 357-362)
+  - **WHERE:** `conductor/code_styleguides/python.md`
+  - **WHAT:** Per spec FR4:
+    1. Inventory table (lines 449-456): update the rows:
+       - `dict[str, Any]` ban: ADD a row for `scripts/audit_boundary_layer.py --strict` (implemented this track; reads `boundary_layer_allowlist.toml`; `--no-allowlist` audits all). KEEP the existing `audit_weak_types.py --strict` row (they catch overlapping but distinct shapes — weak_types catches `Any` in any position; boundary_layer specifically targets `dict[str, Any]` in *signatures* outside the allowlisted boundary).
+       - `Optional[T]` returns: change the row from "audit_optional_in_3_files.py covering 4 baseline files" to "audit_optional_returns.py --strict covering all src/*.py; reads audit_optional_returns.baseline.json for the 3 history.py residuals until cruft_elimination Phase 6". Mark "✅ implemented".
+       - Local imports + `_PREFIX` aliasing + repeated `.from_dict()`: change `audit_imports.py` row to "✅ implemented" (was "⚠️ not yet built" — wrong; the script exists at `scripts/audit_imports.py`).
+       - Repeated `.from_dict()`: drop "(no script planned; relies on Tier 2 review)" — covered by `audit_imports.py`.
+    2. §17.8 enforcement section (lines 357-362): rewrite the bullets per spec FR4:
+       - Bullet for `audit_optional_returns.py` → reflects rename + all-src scope.
+       - Bullet for `audit_imports.py` → drop the "(planned per §17.9a)" parenthetical; mark as implemented.
+       - Bullet for `audit_boundary_layer.py --strict` → replace the "boundary_layer audit (planned...)" bullet; describe the script + allowlist + `--no-allowlist` flag.
+       - The "Pre-commit: every commit MUST pass all four audits above" line → "five audits above" (weak_types, boundary_layer, optional_returns, exception_handling, imports).
+  - **HOW:** Use `manual-slop_edit_file` MCP tool. Verify exact line ranges via `manual-slop_get_file_slice` before editing (the line numbers above are approximate; the actual edit replaces a contiguous block). Preserve CRLF.
+  - **SAFETY:** Pure doc edit. No code. No `src/` changes. No tests changes.
+  - **COMMIT:** `docs(python.md): reconcile §17 inventory + §17.8 with post-track reality`
+  - **GIT NOTE:** Closes C3 (audit_imports.py was "planned" but exists), C18 (audit count), C1+C21 reflected in doc; C2 scope clarified.
+
+- [ ] Task 3.2: Cross-reference sweep for `audit_optional_in_3_files.py` references
+  - **WHAT:** Use `manual-slop_py_find_usages` / `rg` to find ALL references to the old script name across `conductor/` and `docs/`. Per the spec, references likely exist in `error_handling.md:885` + `docs/AGENTS.md §"Convention Enforcement"`. For each reference:
+    - If it's a historical/cross-reference note (e.g., "was `audit_optional_in_3_files.py`"), leave it.
+    - If it's an enforcement-instruction reference (e.g., "run `uv run python scripts/audit_optional_in_3_files.py --strict`"), update to `audit_optional_returns.py`.
+  - **COMMIT:** `docs: update audit_optional_in_3_files.py references to audit_optional_returns.py`
+  - **GIT NOTE:** Historical references preserved (the rename history is documented in python.md:359); enforcement instructions updated.
+
+---
+
+## Phase 4: End-of-Track Report + State Update
+
+- [ ] Task 4.1: Run the full 7-audit strict suite (gate verification)
+  - **WHAT:** Execute all 7 audit scripts (now including the 2 new ones this track ships) in `--strict` mode:
+    ```
+    uv run python scripts/audit_weak_types.py --strict
+    uv run python scripts/audit_boundary_layer.py --strict
+    uv run python scripts/audit_optional_returns.py --strict
+    uv run python scripts/audit_exception_handling.py --strict
+    uv run python scripts/audit_imports.py --strict
+    uv run python scripts/audit_main_thread_imports.py
+    uv run python scripts/audit_no_models_config_io.py
+    ```
+    Expected: all pass (the boundary audit's 2 residuals `hot_reloader.py` + `startup_profiler.py` MUST be in the baseline JSON or the allowlist — verify before this step). The Optional audit's 3 `history.py` residuals are in `audit_optional_returns.baseline.json` (created in Phase 2).
+  - **VERIFY:** If any audit fails, fix the baseline OR the allowlist. Do NOT mask a real violation; document the residual in the end-of-track report instead.
+  - **COMMIT:** `test(audit): verify all 7 audit gates pass --strict post-track`
+  - **GIT NOTE:** The 7-audit strict suite green; the 2 boundary + 3 Optional residuals baselined per spec.
+
+- [ ] Task 4.2: Write end-of-track report
+  - **WHERE:** `docs/reports/TRACK_COMPLETION_enforcement_gap_closure_20260627.md` (NEW file)
+  - **WHAT:** Report following the precedent of `TRACK_COMPLETION_post_module_taxonomy_de_cruft_20260627.md`:
+    - TL;DR
+    - Phase summary (each phase + commits + status)
+    - Verification Criteria status (mapped to spec G1-G8)
+    - File-level changes (new + modified + renamed + new test files)
+    - Commits log (atomic, ordered)
+    - Audit gate status (all 7)
+    - Contradictions closed (C1, C2, C3-partial, C18-partial, C21) and remaining (C5, C6, C16, C17 — deferred per user directive; cite spec OOS)
+    - Known residuals: 2 boundary (`hot_reloader.py`, `startup_profiler.py`) + 3 Optional (`src/history.py`); these are baselined + owned by future tracks
+    - Next steps for the user (review + the recommended follow-up track)
+  - **COMMIT:** `docs(reports): TRACK_COMPLETION_enforcement_gap_closure_20260627`
+  - **GIT NOTE:** End-of-track report; documents contradiction closure + residual baselines.
+
+- [ ] Task 4.3: Update `conductor/tracks.md` + `conductor/chronology.md` + `conductor/tracks/enforcement_gap_closure_20260627/state.toml`
+  - **WHAT:**
+    1. `state.toml`: mark all phases "completed" with their checkpoint SHA; set `status = "completed"` + `current_phase = "complete"`.
+    2. `conductor/tracks.md`: add a row to the Active Tracks table for this track (status "shipped"); or per the convention of recent tracks, the row is added when the track is initiated and the status updated when shipped.
+    3. `conductor/chronology.md`: prepend a row for `2026-06-27 | enforcement_gap_closure_20260627 | shipped | summary...` at the top of the table.
+  - **COMMIT:** `conductor(state): enforcement_gap_closure_20260627 SHIPPED + TRACK_COMPLETION`
+  - **GIT NOTE:** Track state + chronology + tracks.md closed out.
+
+- [ ] Task 4.4: Conductor - User Manual Verification (Protocol in workflow.md)
+  - **WHAT:** Per the workflow.md "Phase Completion Verification and Checkpointing Protocol", present the results to the user for confirmation. Present: the 7-audit strict pass result, the test count, the contradictions closed, and the residual baselines. PAUSE for user sign-off.
+  - **COMMIT:** (no commit; this is the user-confirmation gate)
+  - **GIT NOTE:** User sign-off record.

+# Track Specification: Enforcement Gap Closure (Boundary-Layer Audit + Optional[T] Audit Widening)
+
+## Overview
+
+Close the two genuine enforcement gaps in the 7-banned-pattern mandate documented in
+`conductor/code_styleguides/python.md` §17 (the LLM Default Anti-Patterns):
+
+1. **The boundary-layer audit** — the script that enforces "no `dict[str, Any]`
+   outside the 2-3 wire-parse functions per file" (`python.md` §17.7). Currently
+   marked "⚠️ not yet built" in the §17 enforcement inventory (`python.md:454`),
+   though the cruft_elimination_20260627 Phase 10 only produced a *report*
+   (`docs/reports/boundary_layer_20260628.md`) — never the *audit script*. This
+   is the one that prevents the next LLM from reaching for `dict[str, Any]` in
+   `app_controller.py` again.
+
+2. **The `audit_optional_in_3_files.py` rename + widening** — the script
+   currently named `audit_optional_in_3_files.py` actually checks 4 files
+   (the contradictions report C1+C21) and only enforces the `Optional[T]` ban
+   on those 4 baseline files. `python.md:359` already references a successor
+   `audit_optional_returns.py` (claimed "✅ implemented" in the inventory at
+   `python.md:452`) but the rename never happened and the script never widened
+   to all `src/*.py`. This track lands reality on both the script and the doc.
+
+Both pieces are parallel-safe against the running `post_module_taxonomy_de_cruft_20260627`
+Tier 2 work: this track touches only `scripts/audit_*`, `scripts/*.toml` (allowlists),
+`conductor/code_styleguides/python.md` (the inventory table), and new `tests/test_*`
+files. Zero overlap with `src/models.py`, `tests/test_models*`, `src/api_hooks.py`,
+`scripts/audit_no_models_config_io.py`, or anything else Tier 2 is modifying.
+
+## Current State Audit (as of master `77b70226`, branch `tier2/post_module_taxonomy_de_cruft_20260627` `ddcec7b0`)
+
+### Already Implemented (DO NOT re-implement)
+
+- `scripts/audit_weak_types.py` (388 lines) — flags `dict[str, Any]`, `Any`,
+  anonymous tuple returns; informational default + `--strict` CI gate; reads
+  `scripts/audit_weak_types.baseline.json`. **Implemented, working.** Covers
+  §17.1 (`dict[str, Any]` / `Any` ban) and §17.2 (anonymous tuples) globally.
+
+- `scripts/audit_exception_handling.py` (~500 lines) — classifies
+  `try/except/finally/raise` sites into 10 categories; informational default +
+  `--strict` CI gate. **Implemented, working.** Covers §17.3 (silent swallow /
+  broad catch) globally.
+
+- `scripts/audit_imports.py` (309 lines) — flags local imports (§17.9a),
+  `_PREFIX` aliasing (§17.9b), and repeated `.from_dict()` (§17.9c);
+  informational default + `--strict` CI gate; reads
+  `scripts/audit_imports_whitelist.toml` for vendor-SDK-warmup + hot-reload
+  per-file exemptions. **Implemented, working** (despite `python.md:455-456`
+  marking it "not yet built" — a doc drift this track fixes). Covers §17.9
+  fully.
+
+- `scripts/audit_imports_whitelist.toml` (81 lines) — per-file whitelist with
+  `reason` field + "Last reviewed" header. **The precedent template** for the
+  new `boundary_layer_allowlist.toml` this track creates.
+
+- `scripts/audit_optional_in_3_files.py` (122 lines) — AST-scans 4 files
+  (`src/mcp_client.py`, `src/ai_client.py`, `src/rag_engine.py`,
+  `src/code_path_audit.py`); the `BASELINE_FILES` tuple at line 17-22 is the
+  only thing pinning it to those files; the audit logic is generic
+  (`_return_annotation_is_optional`, `_annotation_is_optional_arg`,
+  `audit_file`). **Implementation 100% reusable; only the file glob +
+  name + docs need to change.**
+
+### Gaps to Fill (This Track's Scope)
+
+- **GAP-1: No boundary-layer audit script exists.** `python.md:454` and
+  `python.md:361` mark it "planned / not yet built". The
+  `cruft_elimination_20260627` spec describes it at FR1 §72 ("Boundary Layer
+  is EXACTLY 2 places") and G14 ("boundary layer is documented as exactly 2
+  places") but only ever delivered a *report* (`boundary_layer_20260628.md`),
+  never a *static audit*. Without this, the §17.7 contract ("2-3 boundary
+  functions per file, everything else must be typed") is policy-without-teeth.
+
+- **GAP-2: `audit_optional_in_3_files.py` name lies + scope is too narrow.**
+  - It actually checks 4 files (mcp_client, ai_client, rag_engine,
+    code_path_audit) but is named "_3_files".
+  - It only covers those 4 baseline files. The §17 mandate requires
+    `Optional[T]` return-types banned in *all* `src/*.py`.
+  - `python.md:359` + `python.md:452` already promise an
+    `audit_optional_returns.py` "covering all `src/*.py`" — but no such
+    script exists. The doc claims reality that the code doesn't match.
+
+- **GAP-3: `python.md` §17 inventory table is internally inconsistent.**
+  Lines 451-456 mark `audit_imports.py` as "not yet built" (false — it exists)
+  and `audit_optional_returns.py` as "implemented" (false — it doesn't exist;
+  only the `audit_optional_in_3_files.py` does). This track corrects both rows
+  to match post-track reality.
+
+### Verified `dict[str, Any]` Distribution on master (the blast-radius for GAP-1)
+
+Per the audit-style AST scan I ran on master at `77b70226` (full scan of all
+`src/*.py`):
+
+| File | ret sites | param sites | has `from_dict` | calls tomllib/json.loads |
+|------|-----------|-------------|------------------|--------------------------|
+| src/theme_models.py | 2 | 2 | yes | yes |
+| src/context_presets.py | 0 | 3 | no | no |
+| src/log_registry.py | 2 | 1 | yes | yes |
+| src/hot_reloader.py | 1 | 1 | no | no |
+| src/mcp_client.py | 0 | 2 | yes | yes |
+| src/personas.py | 1 | 1 | yes | yes |
+| src/presets.py | 1 | 1 | no | yes |
+| src/tool_presets.py | 1 | 1 | yes | yes |
+| src/type_aliases.py | 1 | 1 | yes | no |
+| src/workspace_manager.py | 1 | 1 | yes | yes |
+| src/events.py | 1 | 0 | no | no |
+| src/gemini_cli_adapter.py | 1 | 0 | no | yes |
+| src/openai_compatible.py | 1 | 0 | no | no |
+| src/paths.py | 1 | 0 | no | yes |
+| src/session_logger.py | 0 | 1 | no | no |
+| src/startup_profiler.py | 1 | 0 | no | no |
+| ... 50 other `src/*.py` | 0 | 0 | (varies) | (varies) |
+
+Totals: **12 `dict[str, Any]` returns + 16 params across 16 files**; ~50 other
+files have zero `dict[str, Any]` in signatures.
+
+Per-file manual classification (the same kind of classification the
+`audit_imports_whitelist.toml` makes for hot-reload files):
+
+- **LEGITIMATE BOUNDARY** (audit must allow): `context_presets.py`
+  (`load_all/save_preset/delete_preset(project_dict: Dict[str, Any])` —
+  `project_dict` IS the wire TOML), `events.py` `to_dict()` (wire
+  serialization for the WS protocol), `openai_compatible.py`
+  `_to_dict_tool_call(tc: ToolCall) -> dict[str, Any]` (converts typed
+  `ToolCall` to vendor wire dict), `theme_models.py` (the schema is the wire
+  for `.ini` rendering), `log_registry.py` (JSON-L log shape), `presets.py`,
+  `tool_presets.py`, `personas.py`, `workspace_manager.py`, `paths.py`,
+  `gemini_cli_adapter.py`, `mcp_client.py` (the MCP wire-protocol parsers),
+  `type_aliases.py` (`from_dict(raw: dict[str, Any])` classmethods — the
+  literal definition of boundary), `session_logger.py` (writes JSONL).
+- **GENUINE VIOLATIONS** (audit should flag, baseline captures them so
+  strict stays green until a migration track fixes): `hot_reloader.py`
+  (`capture_state`/`restore_state(app, ...) -> dict[str, Any]` — internal
+  state, could be a `HotReloadSnapshot` dataclass), `startup_profiler.py`
+  (`snapshot() -> dict[str, Any]` — could be a `ProfilerSnapshot` dataclass).
+
+So the audit must:
+1. Find every `dict[str, Any]` in function signatures (param + return +
+   annotated assignment) in every `src/*.py`.
+2. For each site, check whether its enclosing function is allowlisted in
+   `scripts/boundary_layer_allowlist.toml` (per-file + per-function entries
+   with a `reason` field, mirroring the `audit_imports_whitelist.toml`
+   contract).
+3. Exit 1 in `--strict` mode on any *un*-allowlisted site.
+4. Emit a `WHITELISTED` annotation per allowlisted file so the user sees the
+   audit considered it (mirrors the `audit_imports.py` precedent).
+5. Ship an initial `boundary_layer_allowlist.toml` listing the ~14 legitimate
+   boundary files identified above, each with a `reason` field documenting
+   why it's at the wire.
+
+### Verified `Optional[T]` Return-Type Distribution on master (the blast-radius for GAP-2)
+
+Same AST scan, but counting `Optional[X]` return annotations:
+- **Total `RETURN_OPTIONAL` violations: 3, in 1 file** (`src/history.py`)
+- **Total `PARAM_OPTIONAL` (warning only, never blocks strict): 119 across many files**
+  — these are legal per `error_handling.md` ("argument types that may be
+  `None` describe a caller choice, not a runtime failure").
+
+So widening the audit from 4 files → all `src/*.py` surfaces **3 new strict
+violations** in `src/history.py`. The existing `audit_optional_in_3_files.py`
+already covers the 4 baseline files (all clean). This track adds the 3
+`history.py` sites to a new `audit_optional_returns.baseline.json` so the
+widened strict gate stays green until cruft_elimination Phase 6 (which owns
+those 3 sites) actually migrates them. The 3 sites are documented in the
+allowlist; they are NOT fixed by this track (out of scope; the fix belongs to
+the cruft_elimination Phase 6 Optional[T]-migration work).
+
+## Goals
+
+- **G1.** A working `scripts/audit_boundary_layer.py` that AST-scans all
+  `src/*.py` for `dict[str, Any]` in function signatures (params, returns,
+  annotated locals) and exits 1 in `--strict` mode on any un-allowlisted site.
+
+- **G2.** A working `scripts/boundary_layer_allowlist.toml` that declares the
+  legitimate boundary functions per file, each with a `reason` field, modeled
+  on `audit_imports_whitelist.toml` (with `--show-allowlist` and
+  `--no-allowlist` flags mirroring the imports whitelist precedent).
+
+- **G3.** `audit_optional_in_3_files.py` renamed to
+  `audit_optional_returns.py`, `BASELINE_FILES` replaced with a `src/*.py`
+  glob, docstrings updated to drop the "3 files" fiction. The 3 `history.py`
+  violations baselined in `audit_optional_returns.baseline.json` so strict
+  stays green. Existing strict callers (`code_path_audit_20260607` referenced
+  the old name — update or alias accordingly).
+
+- **G4.** `python.md` §17 enforcement inventory (lines 449-456) corrected to
+  match post-track reality: `audit_boundary_layer.py` implemented, the renamed
+  `audit_optional_returns.py` "scans all `src/*.py`", `audit_imports.py`
+  marked implemented (it already is), and the inventory's "Pre-commit: every
+  commit MUST pass all four audits" line updated to "five audits" (or
+  whatever the actual post-track count is).
+
+- **G5.** `conductor/code_styleguides/error_handling.md` and
+  `conductor/code_styleguides/python.md` references to the renamed script
+  updated (any line saying `audit_optional_in_3_files.py` ->
+  `audit_optional_returns.py`, except the one legacy cross-reference note
+  in `python.md:359` documenting the rename history).
+
+- **G6.** New tests in `tests/test_audit_boundary_layer.py` (≥10 tests:
+  finder detects `dict[str, Any]` in return / param / local annotation;
+  allowlist suppresses findings + emits WHITELISTED; `--strict` exits 1 on
+  un-allowlisted site, exits 0 on allowlisted; `--json` output shape; missing
+  file handling; syntax error handling).
+
+- **G7.** New/updated tests in `tests/test_audit_optional_returns.py`
+  (or update existing test file if one references the old name): ≥5 tests
+  confirming the widened scope, the rename, baseline reading, and
+  `--strict` behavior.
+
+- **G8.** End-of-track report at
+  `docs/reports/TRACK_COMPLETION_enforcement_gap_closure_20260627.md`
+  documenting what shipped + the residual violation baselines + any
+  contradictions from `CONTRADICTIONS_REPORT_20260627.md` closed (C1, C2,
+  C3-partial, C18-partial, C21) and which remain (C5, C6, C16, C17 — those
+  are docs-sync items deferred until tier2 stabilizes, per user directive
+  2026-06-27).
+
+## Functional Requirements
+
+### FR1: `scripts/audit_boundary_layer.py`
+
+- **CLI contract** mirrors `audit_exception_handling.py` + `audit_imports.py`:
+  - `uv run python scripts/audit_boundary_layer.py` — informational (exits 0)
+  - `uv run python scripts/audit_boundary_layer.py --strict` — exits 1 on
+    any un-allowlisted `dict[str, Any]` signature site
+  - `uv run python scripts/audit_boundary_layer.py --json` — JSON output
+  - `uv run python scripts/audit_boundary_layer.py --show-allowlist` —
+    prints the current allowlist + reasons, exits 0
+  - `uv run python scripts/audit_boundary_layer.py --no-allowlist` —
+    audits all sites regardless of allowlist (for one-off audits)
+- **Detection contract** — finds `dict[str, Any]` in:
+  - function return annotations (`def f(...) -> dict[str, Any]`)
+  - function parameter annotations (`def f(x: dict[str, Any])`)
+  - annotated assignments to locals at function scope
+    (`acc: dict[str, dict[str, Any]] = {}` — common pattern in vendor adapters)
+- **Allowlist contract** — reads `scripts/boundary_layer_allowlist.toml`.
+  Per-file entries: `[allowlist."<relative_path>"] reason = "..."`. Within
+  an allowlisted file, ALL `dict[str, Any]` sites are suppressed with a
+  single `WHITELISTED` annotation per file (mirrors `audit_imports.py`
+  precedent; per-line entries would be brittle because the same file has
+  multiple boundary functions). Use `--no-allowlist` to ignore the allowlist.
+- **Coverage:** all `src/*.py`. The audit does NOT traverse `tests/`,
+  `scripts/`, `simulation/` — those aren't subject to §17.7.
+- **Defaults:** informational mode prints a summary table (file, sites,
+  allowlisted?) + a list of violations. `--strict` prints the same and
+  exits 1 if there are un-allowlisted sites.
+- **Source:** 1-space indent, no comments in body, type-hinted, docstrings
+  where the contract is non-obvious. Module docstring explains the §17.7
+  contract + the allowlist pattern.
+
+### FR2: `scripts/boundary_layer_allowlist.toml`
+
+- TOML file modeled on `audit_imports_whitelist.toml`:
+  - Header comment block explaining the purpose + the format.
+  - "Last reviewed: 2026-06-27"
+  - `[allowlist."<relative_path>"]` entries for each legitimate boundary
+    file with a `reason` field documenting why it's at the wire boundary.
+- **Initial contents:** the ~14 legitimate boundary files identified in the
+  Current State Audit (`context_presets.py`, `events.py`,
+  `openai_compatible.py`, `theme_models.py`, `log_registry.py`, `presets.py`,
+  `tool_presets.py`, `personas.py`, `workspace_manager.py`, `paths.py`,
+  `gemini_cli_adapter.py`, `mcp_client.py`, `type_aliases.py`,
+  `session_logger.py`). The two genuine violators (`hot_reloader.py`,
+  `startup_profiler.py`) are NOT in the allowlist — the audit will flag them
+  on master, but `audit_boundary_layer.baseline.json` will record them so
+  `--strict` stays green until a future track migrates them.
+
+### FR3: Rename + widen `audit_optional_in_3_files.py` → `audit_optional_returns.py`
+
+- **Rename:** `git mv scripts/audit_optional_in_3_files.py
+  scripts/audit_optional_returns.py` (preserves git history).
+- **Code changes:**
+  - Module docstring: drop "4 baseline files"; say "all `src/*.py` per
+    §17 post-2026-06-27 widening".
+  - `BASELINE_FILES: tuple[str, ...] = (...)` → `def _discover_src_files() ->
+    list[Path]: return sorted(Path("src").glob("*.py"))` (the precedent is
+    `audit_exception_handling.py`'s glob approach).
+  - `audit_file()` is already generic — no logic change.
+  - Output: the summary line says "scanned N files" with N = the count.
+- **Baseline file:** create `scripts/audit_optional_returns.baseline.json`
+  recording the 3 `src/history.py` `RETURN_OPTIONAL` violations so
+  `--strict` stays green. The strict-mode behavior: exit 1 if findings >
+  baseline, exit 0 otherwise. (Mirrors `audit_weak_types.py`'s baseline +
+  `--strict` contract — see `audit_weak_types.baseline.json`.)
+- **Backward-compat:** The old name `audit_optional_in_3_files.py` is gone.
+  Any external references to the old name must be updated. (Per the
+  pre-flight grep, references exist in `python.md:359`, `python.md:452`,
+  and possibly `error_handling.md` — those are doc edits in G5. The
+  `code_path_audit_20260607` track's plan referenced the old name as a
+  cross-reference contract — that's historical; not updated.)
+
+### FR4: `python.md` §17 enforcement inventory + §17.8 enforcement section
+
+- **§17 inventory table (lines 449-456)** corrected:
+  - Row for `dict[str, Any]` ban: `audit_weak_types.py` (implemented) +
+    `audit_boundary_layer.py --strict` (implemented this track) — BOTH
+    listed, with the boundary audit's note: "uses
+    `scripts/boundary_layer_allowlist.toml`; use `--no-allowlist` to audit
+    all `src/*.py` without suppression."
+  - Row for `Optional[T]` returns: `audit_optional_returns.py` (renamed +
+    widened to all `src/*.py` this track; reads
+    `audit_optional_returns.baseline.json` for the 3 `history.py` residuals
+    until cruft_elimination Phase 6).
+  - Row for local imports + aliasing + repeated `from_dict()`:
+    `audit_imports.py` — marked "✅ implemented" (CORRECTED from current
+    "⚠️ not yet built").
+  - Row for repeated `.from_dict()`: same as above (covered by
+    `audit_imports.py`).
+- **§17.8 enforcement section (lines 357-362)** updated:
+  - Bullet for `audit_optional_returns.py` → reflects rename + widening.
+  - Bullet for `audit_imports.py` → marked implemented (drop the parenthetical
+    "planned in §17.9a").
+  - Bullet for "boundary_layer audit (planned...)" → replaced with bullet
+    for `audit_boundary_layer.py --strict` (implemented, references
+    `boundary_layer_allowlist.toml`).
+  - The "Pre-commit: every commit MUST pass all four audits above" line →
+    "five audits" (weak_types, boundary_layer, optional_returns,
+    exception_handling, imports).
+
+### FR5: Test files
+
+- **`tests/test_audit_boundary_layer.py`** (NEW) — ≥10 tests:
+  - `test_finder_detects_dict_return_annotation` — synthetic .py with a
+    `def f() -> dict[str, Any]: ...` → finding emitted.
+  - `test_finder_detects_dict_param_annotation` — `def f(x: dict[str, Any])`
+    → finding emitted.
+  - `test_finder_detects_dict_local_assignment` — `acc: dict[str, Any] = {}`
+    inside a function → finding emitted.
+  - `test_finder_ignores_non_dict_any` — `def f() -> dict[str, int]` → no
+    finding.
+  - `test_allowlist_suppresses_findings` — file in allowlist → findings
+    suppressed, `WHITELISTED` annotation emitted instead.
+  - `test_strict_exits_1_on_violation` — un-allowlisted violation → exit 1.
+  - `test_strict_exits_0_when_allowlisted` — allowlisted file → exit 0.
+  - `test_json_output_shape` — `--json` output has the expected top-level
+    keys (`files_scanned`, `files_with_findings`, `total_findings`,
+    `by_kind`, `findings`).
+  - `test_missing_file_handling` — referenced file absent → graceful
+    `MISSING_FILE` finding, not a crash.
+  - `test_syntax_error_handling` — malformed .py → graceful `SYNTAX_ERROR`
+    finding, not a crash.
+  - `test_show_allowlist_flag` — `--show-allowlist` prints entries, exits 0.
+- **`tests/test_audit_optional_returns.py`** (NEW) — ≥5 tests:
+  - `test_renamed_script_exists` — `scripts/audit_optional_returns.py`
+    exists; `scripts/audit_optional_in_3_files.py` does NOT.
+  - `test_scans_all_src_files` — audit finds a synthetic `Optional[X]`
+    return in a new file under `src/` that wasn't in the old 4-file
+    baseline. (Use `monkeypatch` to point at a `tmp_path` src/ tree.)
+  - `test_baseline_reading_keeps_strict_green` — with 3 known `history.py`
+    sites baselined, `--strict` exits 0.
+  - `test_strict_exits_1_above_baseline` — add 1 new `Optional[X]` return
+    not in baseline → exit 1.
+  - `test_param_optional_is_warning_not_strict` — `PARAM_OPTIONAL`
+    findings never cause `--strict` to exit 1.
+
+## Non-Functional Requirements
+
+- **1-space indentation** for all Python code (hard rule per workflow.md).
+- **No comments in body** per AGENTS.md "No comments to source code".
+- **CRLF line endings** preserved on Windows (use `manual-slop_edit_file`
+  MCP tool, not native `edit`, to preserve formatting per workflow.md).
+- **Atomic per-task commits** — never batch; one task = one commit + one
+  plan/state update commit.
+- **No diagnostic noise** — no `sys.stderr.write("[FOO] ...")` lines in
+  the audit scripts.
+- **`--json` mode** produces machine-readable output for CI integration.
+- **Default mode** is informational (exit 0) per the precedent of every
+  other audit script; `--strict` is the CI gate.
+- **Performance** — the audit scans all `src/*.py` (~66 files); AST parse
+  + walk should complete in well under 1 second wall-clock (the existing
+  `audit_weak_types.py` does the same scale and is sub-second).
+
+## Architecture Reference
+
+- **`docs/guide_meta_boundary.md`** — the domain-distinction rule; the
+  boundary layer is an Application concept, not a meta-tooling one.
+- **`docs/reports/boundary_layer_20260628.md`** — the *report* this audit
+  *implements*. Lists every legitimate `Metadata` usage and explains why
+  each is at the wire boundary.
+- **`conductor/code_styleguides/python.md` §17.7** — the §17.7 contract:
+  "the ONLY place these patterns are allowed is at the literal wire
+  boundary — the function that calls `tomllib.load()`, `json.loads()`, or
+  a vendor SDK's response parser. The boundary is 2-3 functions per file."
+- **`conductor/code_styleguides/data_oriented_design.md` §8.5** — the
+  Python Type Promotion Mandate (the canonical rule this audit enforces).
+- **`conductor/code_styleguides/error_handling.md`** — the `Optional[T]`
+  ban (and the `Result[T]` + `NIL_T` replacement pattern).
+- **`scripts/audit_imports.py` + `scripts/audit_imports_whitelist.toml`** —
+  the precedent template: AST scan + per-file allowlist + `--strict` CI gate
+  + `--json` / `--show-whitelist` / `--no-whitelist` flags. The new
+  `audit_boundary_layer.py` should match this contract closely.
+- **`scripts/audit_weak_types.py` + `scripts/audit_weak_types.baseline.json`** —
+  the precedent for the `--strict` baseline-JSOא contract (baseline of known
+  violations; `--strict` exits 1 if current findings exceed baseline). The
+  renamed `audit_optional_returns.py` reuses this pattern for the 3
+  `history.py` residuals.
+- **`docs/reports/CONTRADICTIONS_REPORT_20260627.md`** — the source of the
+  contradictions this track closes: C1 (audit name vs behavior), C2
+  (Optional ban scope ambiguity), C3 (audit_imports "planned" but actually
+  built), C18 (2/7 vs actually 4/7 patterns audited), C21 (script name).
+- **`docs/reports/TRACK_COMPLETION_post_module_taxonomy_de_cruft_20260627.md`**
+  — current state of the running parallel track; confirms zero file-overlap.
+
+## Out of Scope
+
+- **Fixing the 3 `src/history.py` `Optional[T]` returns.** Those belong to
+  `cruft_elimination_20260627` Phase 6 (the deferred Optional[T]-returns
+  migration work). This track only *baselines* them so the widened strict
+  gate stays green; the actual migration is the future track's job.
+- **Fixing the 2 `hot_reloader.py` + `startup_profiler.py` `dict[str, Any]`
+  violations.** Same logic: baseline only; a future track migrates them to
+  typed dataclasses (`HotReloadSnapshot`, `ProfilerSnapshot`).
+- **Docs-count drift in `docs/Readme.md`** (providers 5→8, tests 322→251,
+  commands 50+→33). Per user directive 2026-06-27: wait for tier2 branch
+  to stabilize before touching `docs/Readme.md`.
+- **Styleguide §10 Anti-OOP self-contradiction (C16)** and
+  **`type_aliases.md` line 19 table (C17)** — both deferred per user
+  directive (they describe code state that only exists post-merge of the
+  tier2 taxonomy branches; fixing them now would make master's docs
+  describe code master doesn't have).
+- **`RAGChunk.id` field in `guide_rag.md` (C6)** — same branch-sensitivity
+  reason; deferred.
+- **Building the "repeated `.from_dict()` in same expression" enforcement.**
+  `audit_imports.py` already covers it per §17.9c. No new script needed.
+- **Building `scripts/audit_optional_returns.py` baseline migration path.**
+  The 3 `history.py` sites are simply added to the initial baseline JSON;
+  no migration script is needed.
+- **Wire `--strict` mode of `audit_boundary_layer.py` into actual pre-commit
+  hooks in the main repo's `.git/hooks/`.** Per C4 in the contradictions
+  report, pre-commit enforcement is sandbox-only for now; main-repo wiring
+  is a separate track.
+- **Touching any `src/*.py` source.** This track is pure audit +
+  styleguide + tests. Zero `src/` edits.

+# Plan: fix_mma_concurrent_tracks_sim_20260627
+
+3 phases, 4 tasks, 3-5 atomic commits. Per-task TDD red-first. The "test" is the existing failing test in `tests/test_mma_concurrent_tracks_sim.py`; the "fix" is the production code in `src/app_controller.py` and the mock in `tests/mock_concurrent_mma.py`.
+
+## Phase 0: Instrument + diagnose (Tier 2, 1 commit)
+
+**Focus:** Per workflow.md "The Deduction Loop (kill it)", you are allowed to run a failing test at most 2 times in a single investigation. After 2 failures, STOP running the test. Read the code, predict the failure mode, and instrument ALL the relevant state in one pass. So Phase 0 is the instrumentation pass.
+
+- [ ] **Task 0.1** [Tier 2]: Add stderr diagnostics to `src/app_controller.py:_start_track_logic_result`
+  - WHERE: `src/app_controller.py:4750-4840` (the `_start_track_logic_result` function)
+  - WHAT: Add 3 stderr write/flush calls:
+    1. BEFORE `conductor_tech_lead.generate_tickets(goal, skeletons)` — log title, goal
+    2. AFTER `generate_tickets` returns — log length of `raw_tickets`
+    3. INSIDE the `except` block at line 4831 — log full traceback via `import traceback; traceback.print_exc()`
+  - HOW: `manual-slop_edit_file` surgical edit (3-10 lines per edit)
+  - SAFETY: `uv run -m pytest tests/test_mma_concurrent_tracks_sim.py -v` still parses (py_check_syntax exits 0)
+  - INSTRUMENTATION LIFETIME: This commit is INTERIM. The instrumentation must be removed in Phase 2 once the root cause is identified. (Per AGENTS.md "No Diagnostic Noise in Production".)
+- [ ] **COMMIT 0.1:** `chore(diag): add stderr instrumentation to _start_track_logic_result` (Tier 2)
+- [ ] **GIT NOTE:** "Temporary instrumentation to diagnose test_mma_concurrent_tracks_execution failure. Will be removed in the next commit after root cause is identified."
+
+- [ ] **Task 0.2** [Tier 2]: Run the test in isolation with the instrumentation
+  - HOW: `uv run -m pytest tests/test_mma_concurrent_tracks_sim.py::test_mma_concurrent_tracks_execution -v -s > tests/artifacts/tier2_state/fix_mma_concurrent_tracks_sim_20260627/test_run_0.log 2>&1`
+  - Per workflow.md: redirect to log file (NEVER filter output, NEVER use `head`/`tail`)
+  - Read the log file: `manual-slop_read_file tests/artifacts/tier2_state/fix_mma_concurrent_tracks_sim_20260627/test_run_0.log`
+  - Identify the failure mode for the 2nd track
+  - **DO NOT** run the test more than 2 times in total (workflow.md "Deduction Loop")
+
+## Phase 1: Fix the root cause (Tier 3, 1-2 commits)
+
+**Focus:** Based on Phase 0 diagnosis, fix the actual root cause.
+
+- [ ] **Task 1.1** [Tier 3]: Fix the root cause in `src/app_controller.py` OR `tests/mock_concurrent_mma.py`
+  - **If Phase 0 diagnosis is "mock routing broken for 2nd call"** (cause A in spec):
+    - WHERE: `tests/mock_concurrent_mma.py` (the routing logic at lines 64-90)
+    - WHAT: The `gemini_cli_adapter` reuses the session_id returned by the previous call. So track-b's call comes in with `--resume mock-sprint-A` (the session_id returned by the previous track's sprint call). The mock must handle this case.
+    - HOW: Add a routing case for `if session_id == "mock-sprint-A" and call_n == N: _emit_sprint_ticket("B")` — but ALSO handle the case where the gemini_cli_adapter passes the latest session_id for both the track-b sprint call and the track-b worker call.
+    - The cleanest fix: don't rely on session_id alone. After epic + sprint-A, the next call is ALWAYS track-b sprint (since we only have 2 tracks). Add a per-call counter that maps to (call_n // 2) % 2 for the track index.
+  - **If Phase 0 diagnosis is "production bug" (cause B/C/D in spec):**
+    - WHERE: `src/app_controller.py:_start_track_logic_result` (line 4750-4840)
+    - WHAT: Fix the specific bug (disk I/O, flat dict missing field, silent exception)
+    - HOW: Surgical `manual-slop_edit_file` fix
+    - SAFETY: `uv run -m pytest tests/test_mma_concurrent_tracks_sim.py -v` shows PASS
+- [ ] **COMMIT 1.1:** `fix(mma_concurrent): fix 2nd track _start_track_logic not firing` (Tier 3)
+  - Commit message body: explain which root cause was identified and what was changed.
+- [ ] **GIT NOTE:** "Fixes test_mma_concurrent_tracks_execution by <specific fix>."
+
+- [ ] **Task 1.2** [Tier 2]: Run the test in isolation to verify the fix
+  - HOW: `uv run -m pytest tests/test_mma_concurrent_tracks_sim.py::test_mma_concurrent_tracks_execution -v > tests/artifacts/tier2_state/fix_mma_concurrent_tracks_sim_20260627/test_run_1.log 2>&1`
+  - Read the log file and verify PASS
+  - If still failing, **STOP and report to the user** (per workflow.md "Surrender" anti-pattern is OK only after the 5-step checklist)
+
+- [ ] **Task 1.3** [Tier 2]: Run the targeted tier-3 batched test suite to verify no regressions
+  - HOW: `uv run python scripts/run_tests_batched.py --tier tier-3-live_gui > tests/artifacts/tier2_state/fix_mma_concurrent_tracks_sim_20260627/test_run_tier3.log 2>&1`
+  - Verify: 0 failures in tier-3
+  - Per workflow.md "Isolated-Pass Verification Fallacy" — the only verification that matters is the batched run, not the isolated run
+
+## Phase 2: Remove instrumentation + write report (Tier 2, 1-2 commits)
+
+**Focus:** Clean up the temporary instrumentation and write the end-of-track report.
+
+- [ ] **Task 2.1** [Tier 2]: Remove the stderr instrumentation from `src/app_controller.py:_start_track_logic_result`
+  - WHERE: `src/app_controller.py:4750-4840` (where the 3 stderr lines were added in Phase 0)
+  - WHAT: Remove the 3 stderr write/flush calls
+  - HOW: `manual-slop_edit_file` surgical edit (3 sites)
+  - SAFETY: `git grep "_start_track_logic_result.*stderr" src/app_controller.py` returns 0 hits
+- [ ] **COMMIT 2.1:** `chore(cleanup): remove diagnostic instrumentation from _start_track_logic_result` (Tier 2)
+- [ ] **GIT NOTE:** "Removes the temporary stderr instrumentation added in 0.1. The bug fix is in 1.1; this is cleanup."
+
+- [ ] **Task 2.2** [Tier 2]: Update `docs/reports/OUTSTANDING_MMA_TEST_FAILURES_20260627.md` to RESOLVED
+  - WHERE: `docs/reports/OUTSTANDING_MMA_TEST_FAILURES_20260627.md` (the "4. UNRESOLVED" section)
+  - WHAT: Replace "⚠️ UNRESOLVED" with "✅ RESOLVED" and add a link to the fixing commit
+  - HOW: `manual-slop_edit_file` surgical edit
+- [ ] **COMMIT 2.2:** `docs(report): mark OUTSTANDING_MMA_TEST_FAILURES_20260627.md as RESOLVED` (Tier 2)
+- [ ] **GIT NOTE:** "Per FR8 of the track spec. The MMA concurrent tracks test is now passing in the batched test suite."
+
+- [ ] **Task 2.3** [Tier 2]: Write `docs/reports/TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md`
+  - WHERE: `docs/reports/TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md` (new file)
+  - WHAT: Follow the precedent of `TRACK_COMPLETION_post_module_taxonomy_de_cruft_20260627.md`:

+    - The 1 root cause fixed in this track
+    - Files changed
+    - Verification results
+    - Suggested next steps
+  - HOW: `Write` tool to create the file
+- [ ] **COMMIT 2.3:** `docs(reports): TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627` (Tier 2)
+- [ ] **GIT NOTE:** "End-of-track report. Track is complete; tier-3 of post_module_taxonomy_de_cruft_20260627 is now PASS."

+
+## Notes for Tier 3 worker (Phase 1)
+
+- The "test" is `tests/test_mma_concurrent_tracks_sim.py::test_mma_concurrent_tracks_execution`. It is the spec.
+- The fix is in `src/app_controller.py:_start_track_logic_result` OR `tests/mock_concurrent_mma.py`. Choose based on Phase 0 diagnosis.
+- Use `manual-slop_edit_file` for surgical edits (3-10 lines per edit).
+- 1-space indentation. CRLF line endings. No comments.
+- Per `conductor/code_styleguides/python.md` §17: no `dict[str, Any]`, no `Any`, no `Optional[T]`, no `hasattr()` for entity dispatch.
+- If the fix requires changing the mock's response shape, do NOT change the test — the test exercises the production pipeline.
+
+## Notes for Tier 2 reviewer (Phases 0 and 2)
+
+- Phase 0 is the instrumentation pass. The diagnostics are INTERIM and must be removed in Phase 2.
+- Phase 1 is the fix. Read the test log from Phase 0 BEFORE choosing the fix; don't guess.
+- Phase 2 is cleanup + report.
+- Per `AGENTS.md` HARD BAN: no `git restore`, no `git checkout`, no `git reset`, no `git stash`.
+- Per `AGENTS.md` "No Diagnostic Noise in Production": the instrumentation in Phase 0 must be removed in Phase 2.
+- Per `conductor/workflow.md` "Pre-commit verification gate": after every commit, run `git diff --cached --stat` + `git show HEAD --stat` + `uv run python scripts/audit_tier2_leaks.py --strict`.

+# Track Specification: fix_mma_concurrent_tracks_sim_20260627
+
+## Overview
+
+Single-test fix track. The `tier-3-live_gui::test_mma_concurrent_tracks_sim::test_mma_concurrent_tracks_execution` test was failing on the `tier2/post_module_taxonomy_de_cruft_20260627` branch. Per the user directive ("those issues must get resolved we are not sweeping them under the rug"), this track fixes the test to pass in the batched test suite, ships it, and the parent branch is then ready for review.
+
+The test exercises the full concurrent-MMA flow: plan an epic (returns 2 proposed tracks), accept both, start both concurrently, verify both ticket-A and ticket-B workers appear, verify both tracks complete. The failure was at "accept-tracks" — after `btn_mma_accept_tracks`, only 1 of the 2 proposed tracks was created in the project.
+
+This track is the **TDD fix for one specific test**. It is NOT a sweep or a refactor; it is a focused investigation + fix + verification.
+

+
+## The 4 Stacked Regressions (Root Cause Analysis)
+
+### 1. `flat_config()` return type change (PRODUCTION BUG — FIXED in 635ca552)
+
+`flat_config()` in `src/project.py` was changed by `cruft_elimination_20260627` (commit 0d2a9b5e) from `dict[str, Any]` to a **frozen `@dataclass ProjectContext`**. The change was semantic, not just cosmetic. But 3 sites in `src/app_controller.py` mutated the returned object:
+
+- `_do_generate` (line 4027): `flat["files"] = ...; flat["files"]["paths"] = ...`
+- `_cb_plan_epic` (line 4604): `flat.setdefault("files", {})["paths"] = ...`
+- `_start_track_logic_result` (line 4793): `flat.setdefault("files", {})["paths"] = ...`
+
+Each raised `TypeError: 'ProjectContext' object does not support item assignment`.
+
+**Fix in 635ca552:** Call `flat.to_dict()` to get a mutable dict.
+
+### 2. `topological_sort()` return type change (PRODUCTION BUG — FIXED in 635ca552)
+
+`conductor_tech_lead.topological_sort()` in `src/mma_conductor.py` was changed (also in commit 0d2a9b5e) from `list[str]` to `list[Ticket]`. The `_start_track_logic_result` consumer used dict-style access (`t_data["id"]`, `t_data.get("description")`).
+
+**Fix in 635ca552:** Use Ticket attribute access (`t_data.id`, `t_data.description`, etc.).
+
+### 3. `gemini_cli_adapter` `--resume` session reuse (MOCK BUG — FIXED in 635ca552)
+
+The gemini_cli_adapter now reuses the session_id from the epic call (`mock-epic`) for all subsequent Tier 2/3 calls via `--resume mock-epic`. The original mock `tests/mock_concurrent_mma.py` was written when each LLM call was stateless; it routed on prompt substrings ("PATH: Epic Initialization", "generate the implementation tickets", "You are assigned to Ticket"). In resume mode the prompt is empty (the session is the context), so the routing fell to the default case.
+
+**Fix in 635ca552:** Parse `--resume` from `sys.argv` and use a persistent file-based call counter to route to per-track responses.
+
+### 4. ⚠️ UNRESOLVED — 2nd track's `_start_track_logic` never fires
+
+After fixes 1-3, the test still fails: only 1 sprint-ticket mock call is observed (for track-a); the 2nd call for track-b never happens. The 30-second test poll times out.
+
+**Hypothesized root cause:** `_start_track_logic` for track-a either hangs OR fails silently. The for loop in `_cb_accept_tracks._bg_task` continues to track-b which also calls `_start_track_logic` and also fails/hangs. The test poll times out before either track completes.
+
+**Possible causes to investigate:**
+- `conductor_tech_lead.generate_tickets(goal, skeletons)` returns `[]` (no tickets) for track-a when the adapter can't reuse the session properly → no track created, no error
+- `project_manager.save_track_state(track_id, state, ...)` blocks on disk I/O
+- The IO pool is saturated (the bg_task is `submit_io(_bg_task)` and each `_start_track_logic` is synchronous on its own thread)
+- `aggregate.run(flat)` hangs (the new `flat.to_dict()` conversion may be missing a field that `aggregate.run` requires)
+- The exception in `except (OSError, IOError, ValueError, TypeError, KeyError, AttributeError, RuntimeError) as e:` at line 4831 catches an exception and returns `Result(data=None, errors=[err])` — but the caller `_start_track_logic` (line 4744) prints `ERROR in _start_track_logic: {err.message}` and continues to the next track in the loop, which also fails. The test poll times out because no track is appended to `self.tracks`.
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | Diagnose why only 1 of 2 tracks is created in `_cb_accept_tracks._bg_task` | stderr diagnostics + log file show the actual failure mode for each track |
+| G2 | Fix the production OR test-mock bug that causes the 2nd track to fail | Test passes in isolation AND in the full batched suite |
+| G3 | Update `docs/reports/OUTSTANDING_MMA_TEST_FAILURES_20260627.md` to reflect the fix | Report shows RESOLVED status |
+| G4 | Tier 3 of `tier2/post_module_taxonomy_de_cruft_20260627` goes from FAIL to PASS | `uv run python scripts/run_tests_batched.py --tier tier-3-live_gui` shows 0 failures |
+| G5 | All 11 batched test tiers pass | `uv run python scripts/run_tests_batched.py` shows 11/11 PASS (or pre-existing RAG flake) |
+
+## Non-Goals
+
+- Refactoring the MMA concurrent execution engine (`src/multi_agent_conductor.py`)
+- Refactoring `_cb_accept_tracks` or `_start_track_logic` beyond the minimum fix
+- Refactoring `tests/mock_concurrent_mma.py` beyond the minimum fix
+- Adding new tests for MMA concurrent execution
+- Fixing any other tier failures (RAG flake is pre-existing and out of scope)
+- Updating `conductor/tracks/post_module_taxonomy_de_cruft_20260627/spec.md` (the parent track is SHIPPED; this is a follow-up)
+
+## Functional Requirements
+
+### FR1: Instrument `_start_track_logic_result` with stderr diagnostics (Tier 3)
+
+Add 3 `sys.stderr.write` + `sys.stderr.flush` calls:
+1. BEFORE `conductor_tech_lead.generate_tickets(goal, skeletons)` — log title, goal
+2. AFTER `generate_tickets` returns — log length of `raw_tickets`
+3. INSIDE the `except` block at line 4831 — log full traceback via `import traceback; traceback.print_exc()`
+
+**WHY:** Per workflow.md "The Deduction Loop (kill it)", you are allowed to run a failing test at most 2 times in a single investigation. After 2 failures, STOP running the test. Read the code, predict the failure mode, and instrument ALL the relevant state in one pass.
+
+### FR2: Run the test in isolation (Tier 2)
+
+`uv run -m pytest tests/test_mma_concurrent_tracks_sim.py::test_mma_concurrent_tracks_execution -v -s` and capture:
+- stderr output from `_start_track_logic_result` instrumentation
+- the mock call counter file at `artifacts/.mock_concurrent_mma_call_count`
+- the sloppy.py stderr (via the test's log capture)
+
+**Per workflow.md "Pre-commit verification gate"**, redirect to log file: `... > tests/artifacts/tier2_state/fix_mma_concurrent_tracks_sim_20260627/test_run.log 2>&1`
+
+### FR3: Diagnose the failure mode (Tier 2)
+
+Based on FR2 output, identify ONE of:
+- A. `generate_tickets` returns `[]` (mock routing broken for 2nd call)
+- B. `project_manager.save_track_state` raises (disk I/O issue)
+- C. `aggregate.run(flat)` raises (flat dict missing field)
+- D. The `except` block catches a `RuntimeError` (or other) and the test poll times out
+
+### FR4: Fix the root cause (Tier 3)
+
+**Per the user directive: "we should adjust the tests instead"** — but the test exercises the production code path. The test is the spec; the production must be correct. Fix in this priority order:
+
+1. **If cause A** (mock routing): fix `tests/mock_concurrent_mma.py` to handle the `--resume mock-sprint-A` session reuse (the adapter reuses the session_id returned by the previous call, so track-b's call is `--resume mock-sprint-A` not `--resume mock-epic`).
+2. **If cause B/C/D** (production bug): fix `src/app_controller.py:_start_track_logic_result` to handle the error gracefully, log the error to the test log, and continue to the next track (instead of silently aborting the loop).
+
+### FR5: Verify the test passes in isolation (Tier 2)
+
+`uv run -m pytest tests/test_mma_concurrent_tracks_sim.py::test_mma_concurrent_tracks_execution -v`
+
+Must show PASS.
+
+### FR6: Verify the test passes in the full batched suite (Tier 2)
+
+**Per workflow.md "Isolated-Pass Verification Fallacy"** — the only verification that matters for `live_gui` tests is the batch run. The test must pass with the other tier-3 tests in the suite.
+
+`uv run python scripts/run_tests_batched.py --tier tier-3-live_gui`
+
+Must show 0 failures in tier-3.
+
+### FR7: Verify all 11 tiers pass (Tier 2)
+
+`uv run python scripts/run_tests_batched.py`
+
+**Per user directive ("stop running the batch yourself, ask me")** — ASK the user before running the full 11-tier batch. Show them the targeted tier-3 result first.
+
+Expected: 11/11 PASS (or 10/11 if the RAG flake is the only remaining failure).
+
+### FR8: Update `OUTSTANDING_MMA_TEST_FAILURES_20260627.md` (Tier 2)
+
+Mark the section "4. UNRESOLVED — Second track's `_start_track_logic` never fires" as RESOLVED with a link to the fixing commit.
+
+### FR9: Write `TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md` (Tier 2)
+
+Follow the precedent of `TRACK_COMPLETION_post_module_taxonomy_de_cruft_20260627.md`:
+- Executive summary
+- 3 root causes fixed (the 3 already in 635ca552)
+- The 1 root cause fixed in this track
+- Files changed
+- Verification results
+- Suggested next steps
+
+## Non-Functional Requirements
+
+- NFR1: 1-space indentation
+- NFR2: CRLF line endings on Windows
+- NFR3: No comments in source code
+- NFR4: Per-task atomic commits with git notes
+- NFR5: No new pip dependencies
+- NFR6: Result[T] returns for fallible fns
+- NFR7: No `git restore` / `git checkout` / `git reset` / `git stash` (per AGENTS.md HARD BAN)
+- NFR8: Stderr diagnostics must be removed before the final commit (no diagnostic noise in production per workflow.md)
+
+## Architecture Reference
+
+- `src/app_controller.py:_cb_accept_tracks._bg_task` (line 4635-4682) — the for loop that should create 2 tracks
+- `src/app_controller.py:_start_track_logic_result` (line 4750-4840) — the per-track pipeline
+- `src/multi_agent_conductor.py:ConductorEngine.run` — the engine that spawns workers
+- `src/ai_client.py:gemini_cli_adapter` (or similar) — the adapter that uses `--resume` for session reuse
+- `src/mma_conductor.py:topological_sort` — returns `list[Ticket]` (was `list[str]` pre-cruft)
+- `src/project.py:flat_config` — returns `frozen @dataclass ProjectContext` (was `dict[str, Any]` pre-cruft)
+- `conductor/code_styleguides/error_handling.md` — the Result[T] + nil-sentinel convention

+## Risks
+
+| # | Risk | Likelihood | Mitigation |
+|---|---|---|---|
+| R1 | The instrumentation is incomplete and the failure mode remains hidden | low | Add diagnostics at 3 strategic points: before/after generate_tickets, in the except block |
+| R2 | The fix requires changes to the production code that may regress other tests | medium | Run the full batched test suite after the fix (with user permission) |
+| R3 | The mock fix requires a deeper understanding of the gemini_cli_adapter's session reuse | medium | Read `src/ai_client.py:gemini_cli_adapter` (or similar) to understand the session_id lifecycle |
+| R4 | The test has a 30-second poll that may be too short for the test infrastructure (IO pool + bg_task + subprocess spawn) | low | Document the timing in the test, but don't change the test's poll time (the fix should make the test pass within the existing poll budget) |
+| R5 | The instrumentation leaks into production (per AGENTS.md "No Diagnostic Noise in Production") | low | Remove the instrumentation in the same commit that fixes the bug (or in a follow-up commit) |
+| R6 | The user does not give permission to run the full 11-tier batched test suite | medium | Run only the targeted tier-3 batched test (`--tier tier-3-live_gui`); ask user for the full batch separately |
+
+## Verification Criteria (Definition of Done)
+
+| # | Criterion | Verification |
+|---|---|---|
+| VC1 | The test `test_mma_concurrent_tracks_execution` passes in isolation | `uv run -m pytest tests/test_mma_concurrent_tracks_sim.py -v` shows PASS |
+| VC2 | Tier 3 of the batched test suite passes (0 failures) | `uv run python scripts/run_tests_batched.py --tier tier-3-live_gui` shows 0 failures |
+| VC3 | The instrumentation is removed from `src/app_controller.py` | `git grep "_start_track_logic_result.*stderr" src/app_controller.py` returns 0 hits |
+| VC4 | `OUTSTANDING_MMA_TEST_FAILURES_20260627.md` is updated to RESOLVED | grep "RESOLVED" OUTSTANDING_MMA_TEST_FAILURES_20260627.md returns hits |
+| VC5 | `TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md` is written | `ls docs/reports/TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md` exists |
+| VC6 | All diagnostic stderr lines are removed from `src/app_controller.py` | No `[DEBUG] _start_track_logic:` lines remain in production |
+| VC7 | No `git restore` / `git checkout` / `git reset` / `git stash` used | Audit the git reflog for the branch |

+# Tier 2 Startup Brief: module_taxonomy_refactor_20260627 (v2)
+
+## Context
+
+This is the v2 of the track. v1 had gaps that gave Tier 2 discretion (Tier 2 made inconsistent decisions). **v2 is prescriptive — Tier 2 has ZERO discretion.** Every move is pre-decided in the spec.
+
+The user explicitly stated: "I want to be more careful with how we are organizing things into which file. We can't let tier 2 have full discretion on this. Some stuff deserves to be in a dedicated file, many do not."
+
+## MANDATORY Pre-Action Reading (per agent protocol)
+
+1. `AGENTS.md` — operating rules, especially "File Size and Naming Convention" HARD RULE
+2. `conductor/workflow.md` — the workflow
+3. `conductor/edit_workflow.md` — the edit workflow
+4. `conductor/code_styleguides/data_oriented_design.md` — "Prefer Fewer Types" principle
+5. `conductor/code_styleguides/error_handling.md` — the `Result[T]` convention
+6. `conductor/code_styleguides/type_aliases.md` — the 10 TypeAliases convention
+7. `conductor/code_styleguides/code_path_audit.md` — code path audit styleguide
+8. `conductor/tracks/module_taxonomy_refactor_20260627/spec.md` — **THE v2 SPEC** (read this end-to-end; it defines the 4-criteria rule and the data/view/ops split)
+9. `conductor/tracks/module_taxonomy_refactor_20260627/plan.md` — the v2 plan (16 atomic commits)
+10. `docs/reports/FOLLOWUP_module_taxonomy_refactor_20260627_recoverable.md` — the recovery report (data is NOT lost)
+
+**First commit of this track must include** `TIER-2 READ <list> before module_taxonomy_refactor_20260627 v2` in the message.
+
+## THE 4-CRITERIA DECISION RULE (the taxonomy law)
+
+Every class in `src/models.py` must satisfy at least 1 of these criteria to be SPLIT into its own dedicated file:
+
+| # | Criterion | Threshold |
+|---|---|---|
+| **C1** | Cross-system usage | Consumed by ≥ 3 unrelated systems |
+| **C2** | State machine / lifecycle | Has state machine, lifecycle methods, or business logic |
+| **C3** | Test file already exists | Has its own dedicated `tests/test_*.py` |
+| **C4** | Substantial size | Class body > 30 lines OR class has > 5 fields |
+
+**Apply the rule:**
+- If C1 OR C2 OR C3 is TRUE → **DEDICATED FILE** (new `src/<name>.py` or merged into existing)
+- If NONE of C1, C2, C3 is TRUE but C4 is TRUE → **MERGE INTO DESTINATION** (existing `src/<name>.py`)
+- If NONE of C1, C2, C3, C4 is TRUE → **KEEP in `src/models.py`** (deferred to a follow-up; not worth a move)
+
+**C4 is the LAST criterion.** A class that fails C1, C2, C3 but passes C4 is "big enough to be in its own file" but not important enough to be the main file. Merge it into a logical destination.
+
+## THE DATA/VIEW/OPS SPLIT (the GUI boundary)
+
+**Rule (already established by the user, formalized here):**
+- **data** = dataclasses, registries, business logic, persistence — goes in `src/<system>.py`
+- **view** = ImGui rendering, draw calls, widget setup — goes in `src/gui_2.py` (or `src/<system>_view.py` if gui_2 is too big)
+- **ops** = operations on data (apply_patch, parse_diff, execute_command) — goes in the destination file with the data, NOT in gui_2
+
+**Exceptions to this rule:**
+- `imgui_scopes.py` is the EXCEPTION (per the user). It contains Python `with` context managers for ImGui scopes. It's the glue between data and view; keeping it separate avoids circular imports.
+- Anything that needs to be in `gui_2.py` to avoid cycles goes in `gui_2.py`.
+
+## TIMELINE-IS-IMMUTABLE PRINCIPLE (added 2026-06-27 per user feedback)
+
+When you (the agent) fuck up — make a wrong commit, break a file, take a bad path — your first instinct will be to "undo" the mistake with `git revert`, `git reset`, or `git stash`. **THIS INSTINCT IS WRONG.** The user explicitly stated: "if an agent fucks up, their tendency to want to 'revert' is not correct and instead they must live with the timeline and just do corrections with a new commit."
+
+**The rule:**
+- The git history is IMMUTABLE on this branch. Every commit you've made is part of the record.
+- "Fixing forward" via a new commit makes the user's review EASIER.
+- "Undoing" via `git revert` / `git reset` / `git stash` makes the user's review HARDER (they have to read the diff between the bad and the "fix" to understand what went wrong).
+
+**Correct pattern when you fuck up:**
+1. Pause. Read the actual file. Confirm the state.
+2. Write a NEW commit that fixes the problem. The commit message should briefly say what was wrong and what you fixed.
+3. If the bad commit introduced data corruption that the user will see, the user can `git revert` it during their review — that's the user's choice, not yours.
+4. If you need to recover an old version of a file, use `git show <good-sha>:<path> > <path>` to extract it.
+
+**Wrong pattern (which you must NOT do):**
+- `git revert <sha>` to undo a commit
+- `git reset --hard <sha>` to throw away a bad commit
+- `git stash` to "save" uncommitted work
+- `git checkout <old-sha> -- .` to "go back to when things were good" (and then commit on top)
+
+These are all attempts to rewrite history. They are BANNED. The right answer is always a forward commit.
+
+## HARD BAN: `git stash*` (added 2026-06-27)
+
+`git stash`, `git stash pop`, `git stash apply`, `git stash drop`, `git stash clear` are FORBIDDEN at 3 layers:
+1. `AGENTS.md` HARD BAN
+2. `conductor/tier2/opencode.json.fragment` bash deny rules (top-level + agent-level)
+3. This prompt's Hard Bans list
+
+Stashing throws away the user's in-progress edits silently. If you think you need a stash, you don't — use a NEW BRANCH or a WORKTREE instead.

+### Style
+
+- 1-space indentation (project standard)
+- CRLF line endings
+- No comments in source code (per AGENTS.md)
+- Use `manual-slop_edit_file` for surgical edits
+- Per-phase regression-guard test runs after each phase
+- Preserve backward-compat: when removing a class from `models.py`, KEEP a `from src.<destination> import <class>` re-export line in `models.py`
+
+## Notes for Tier 2 reviewer
+
+- **The v2 track is prescriptive.** Tier 2 has ZERO discretion. Every move is pre-decided in the spec.
+- **Phase 0 is a state reset only** — no code changes. The 5 "damaged" tasks become "pending" with a note explaining the data is intact.
+- **Phase 1 + 2 are DONE** — verify only.
+- **Phase 3 is the main work** — 9 commits (3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i). Each commit is one of: create new file (3a, 3b, 3c) or merge into existing file (3d, 3e, 3f, 3g, 3h, 3i).
+- **Phase 4 deletes `AGENT_TOOL_NAMES`** — 1 commit, 8 consumer site updates.
+- **Phase 5 reduces `src/models.py`** — 1 commit.
+- **Phase 6 is verification** — 3 commits, no code changes.
+- **Total: 16 atomic commits** (down from v1's 22 because the tier 2 work is now prescriptive).
+- **Tier 2 must NOT use `git stash*` for any reason.** Banned at 3 layers.
+- **Tier 2 must NOT use `git revert*` / `git reset*` for any reason.** Banned per AGENTS.md. Use forward commits instead.

+# Plan v2: module_taxonomy_refactor_20260627
+
+8 phases, 14 tasks, 16 atomic commits (post v2 corrections). Per-task TDD red-first. Tier 3 workers execute; Tier 2 reviews per phase. Tier 2 has ZERO discretion — every decision is pre-made in the spec.
+
+## v2 Changes from v1
+
+The v1 plan was correct in structure but lacked JUSTIFICATION for each move. v2 fixes this by:
+1. **Adding the 4-criteria decision rule** at the top of every phase (so Tier 2 knows the rule, not just the result)
+2. **Documenting the data/view/ops split** explicitly (so Tier 2 doesn't put ImGui in random files)
+3. **Banning Tier 2 discretion** — the spec is now prescriptive; Tier 2 executes, doesn't decide
+4. **Adding the "preserve Pydantic proxies in models.py" decision** (so Tier 2 doesn't accidentally try to move them)
+5. **Adding the "view code goes in `gui_2.py`" rule** (so Tier 2 doesn't put new view code in the data files)
+
+## Phase 0: Pre-flight + reset state.toml (Tier 1, 1 commit)
+
+- [x] **Task 0.1** [Tier 1]: Reset the 5 "damaged" tasks in `state.toml` from "damaged" → "pending" with a note explaining the data is intact
+- [x] **Task 0.2** [Tier 1]: Update `state.toml` to reflect the v2 plan (14 tasks instead of 22)
+- [x] **Task 0.3** [Tier 1]: Update `metadata.json` to add VC13 (4-criteria rule documented) and VC14 (data/view/ops split documented)
+- [x] **COMMIT:** `conductor(plan): v2 - reset damaged tasks; document 4-criteria rule + data/view/ops split` (Tier 1)
+- [x] **GIT NOTE:** v2 corrects the v1 spec to be prescriptive (no Tier 2 discretion). Data is intact in models.py; track is recoverable.
+
+## Phase 1: MERGE ImGui LEAKS (DONE — verify only)
+
+- [x] **Task 1.0** [Tier 2]: Verify the 5 commits are still in the branch
+  - `git log --oneline | grep bg_shader\|shaders\|command_palette\|diff_viewer\|patch_modal` returns 5 commits
+  - `git grep -l "imgui_bundle\|from imgui\\." -- 'src/*.py'` returns ONLY `gui_2.py` + `imgui_scopes.py`
+- [x] **VERIFICATION:** VC1 + VC2 (no code changes, no commit)
+
+## Phase 2: MERGE vendor files (DONE — verify only)
+
+- [x] **Task 2.0** [Tier 2]: Verify the 2 commits are still in the branch
+  - `git log --oneline | grep vendor_capabilities\|vendor_state` returns 2 commits
+  - `python -c "from src.ai_client import PROVIDER_CAPABILITIES, VendorMetric"` works
+- [x] **VERIFICATION:** VC3 + VC4 (no code changes, no commit)
+
+## Phase 3: SPLIT `models.py` (the new work — 5 phases, 9 atomic commits)
+
+The critical insight: the data is INTACT in `models.py`. The 5 "damaged" tasks were about destination files not having the class definitions ADDED yet. The data is fine; we just need to copy the class definitions to the destination files.
+
+### Phase 3a: Create `src/mma.py` (1 commit)
+
+- [x] **Task 3a.1** [Tier 3]: Create `src/mma.py` with `ThinkingSegment`, `Ticket`, `Track`, `WorkerContext`, `TrackMetadata`, `TrackState`, `EMPTY_TRACK_STATE`
+  - HOW: `manual-slop_edit_file` to write the new file
+  - Source: copy from `src/models.py` (the class bodies are intact)
+  - Update imports in: `src/multi_agent_conductor.py`, `src/dag_engine.py`, `src/orchestrator_pm.py`, `src/conductor_tech_lead.py`, `src/mma_prompts.py` (and any other consumer)
+  - SAFETY: Run `tests/test_mma_*.py` + `tests/test_dag_engine.py` + `tests/test_orchestration_logic.py` + `tests/test_conductor_engine_v2.py` + `tests/test_ticket_queue.py`
+- [x] **COMMIT:** `refactor(mma): create src/mma.py with MMA Core (split from models.py)` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule (C1=6 systems, C2=state machine, C3=tests, C4=substantial); C5 PRESERVATION: Ticket/Track/WorkerContext/TrackState/TrackMetadata/ThinkingSegment are MMA Core; they live in `src/mma.py`. The existing `src/mma_prompts.py` (171 lines) is the only existing `mma_` prefixed file; it stays.
+
+### Phase 3b: Create `src/project.py` (1 commit)
+
+- [x] **Task 3b.1** [Tier 3]: Create `src/project.py` with `ProjectContext` + 5 sub-dataclasses + config IO (`_clean_nones`, `load_config_from_disk`, `save_config_to_disk`, `parse_history_entries`)
+  - HOW: `manual-slop_edit_file` to write the new file
+  - Source: copy from `src/models.py` (the class bodies are intact) + add the 5 sub-dataclasses from `cruft_elimination_20260627` (805a0619) which are already in `models.py` if the cruft track merged
+  - Update imports in: `src/project_manager.py` + any other consumer
+  - SAFETY: Run `tests/test_project_manager_*.py` + `tests/test_project_context_20260627.py` (the new test from cruft track)
+- [x] **COMMIT:** `refactor(project): create src/project.py with ProjectContext + sub + config IO (split from models.py)` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule (C1=6+ systems, C3=tests, C4=substantial); ProjectContext is the typed return of `project_manager.flat_config()`; the 5 sub-dataclasses model the actual nested dict structure of `flat_config()`'s return.
+
+### Phase 3c: Create `src/project_files.py` (1 commit)
+
+- [x] **Task 3c.1** [Tier 3]: Create `src/project_files.py` with `FileItem`, `Preset`, `ContextPreset`, `ContextFileEntry`, `NamedViewPreset`
+  - HOW: `manual-slop_edit_file` to write the new file
+  - Source: copy from `src/models.py` (the class bodies are intact)
+  - Update imports in: `src/aggregate.py`, `src/app_controller.py`, `src/gui_2.py`, `src/context_presets.py`
+  - SAFETY: Run `tests/test_file_item_model.py` + `tests/test_view_presets.py` + `tests/test_context_presets_*.py` + `tests/test_custom_slices_*.py` + `tests/test_presets.py`
+- [x] **COMMIT:** `refactor(project_files): create src/project_files.py (split from models.py)` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule (C1=cross-system, C3=tests, C4=substantial); these are the file-related project state classes.
+
+### Phase 3d: Merge `Tool` + `ToolPreset` into `src/tool_presets.py` (1 commit)
+
+- [x] **Task 3d.1** [Tier 3]: Add `Tool` and `ToolPreset` class definitions to `src/tool_presets.py`
+  - HOW: `manual-slop_edit_file` to add the classes to the top of `src/tool_presets.py`
+  - Source: copy from `src/models.py` (the class bodies are intact)
+  - Update imports in `src/models.py` (remove the Tool/ToolPreset defs, add `from src.tool_presets import Tool, ToolPreset` for backward compat) — but ONLY if removing from models.py
+  - SAFETY: Run `tests/test_tool_presets_*.py` + `tests/test_bias_models.py` (which test Tool/ToolPreset via models.Tool)
+  - NOTE: This is a MERGE, not a NEW file. The Tool/ToolPreset classes now live in `src/tool_presets.py` (which already had `ToolPresetManager`). Per the 4-criteria rule: C1=NO (just tool_presets), C2=NO, C3=NO, C4=NO — so MERGE.
+- [x] **COMMIT:** `refactor(tool_presets): merge Tool + ToolPreset from models.py into tool_presets.py` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule: Tool/ToolPreset fail C1, C2, C3 (all consumers are in the tool subsystem); C4 is borderline. MERGE into `src/tool_presets.py` which already exists.
+
+### Phase 3e: Merge `BiasProfile` into `src/tool_bias.py` (1 commit)
+
+- [x] **Task 3e.1** [Tier 3]: Add `BiasProfile` class definition to `src/tool_bias.py`
+  - HOW: `manual-slop_edit_file` to add the class
+  - Source: copy from `src/models.py`
+  - Update imports in `src/models.py` (remove BiasProfile def, add `from src.tool_bias import BiasProfile` for backward compat)
+  - SAFETY: Run `tests/test_tool_presets_*.py` + `tests/test_bias_models.py`
+  - Per 4-criteria rule: C1=NO, C2=NO, C3=NO, C4=NO. MERGE.
+- [x] **COMMIT:** `refactor(tool_bias): merge BiasProfile from models.py into tool_bias.py` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule: BiasProfile fails all 4 criteria. MERGE into existing `src/tool_bias.py`.
+
+### Phase 3f: Merge `TextEditorConfig` + `ExternalEditorConfig` into `src/external_editor.py` (1 commit)
+
+- [x] **Task 3f.1** [Tier 3]: Add `TextEditorConfig` and `ExternalEditorConfig` class definitions to `src/external_editor.py`
+  - HOW: `manual-slop_edit_file` to add the classes
+  - Source: copy from `src/models.py`
+  - Update imports in `src/models.py` (remove defs, add `from src.external_editor import TextEditorConfig, ExternalEditorConfig`)
+  - SAFETY: Run `tests/test_external_editor_*.py`
+  - Per 4-criteria rule: C1=NO, C2=NO, C3=NO, C4=NO. MERGE.
+- [x] **COMMIT:** `refactor(external_editor): merge TextEditorConfig + ExternalEditorConfig from models.py into external_editor.py` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule: editor configs are only used by the editor subsystem. MERGE.
+
+### Phase 3g: Merge `Persona` into `src/personas.py` (1 commit)
+
+- [x] **Task 3g.1** [Tier 3]: Add `Persona` class definition to `src/personas.py`
+  - HOW: `manual-slop_edit_file` to add the class
+  - Source: copy from `src/models.py`
+  - Update imports in `src/models.py` (remove Persona def, add `from src.personas import Persona`)
+  - SAFETY: Run `tests/test_personas_*.py` + `tests/test_persona_*.py`
+  - Per 4-criteria rule: C1=NO, C2=NO, C3=NO, C4=NO. MERGE.
+- [x] **COMMIT:** `refactor(personas): merge Persona from models.py into personas.py` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule: Persona is only used by the persona subsystem. MERGE.
+
+### Phase 3h: Merge `WorkspaceProfile` into `src/workspace_manager.py` (1 commit)
+
+- [x] **Task 3h.1** [Tier 3]: Add `WorkspaceProfile` class definition to `src/workspace_manager.py`
+  - HOW: `manual-slop_edit_file` to add the class
+  - Source: copy from `src/models.py`
+  - Update imports in `src/models.py` (remove WorkspaceProfile def, add `from src.workspace_manager import WorkspaceProfile`)
+  - SAFETY: Run `tests/test_workspace_manager_*.py` + `tests/test_workspace_profiles_*.py`
+  - Per 4-criteria rule: C1=NO, C2=NO, C3=NO, C4=NO. MERGE.
+- [x] **COMMIT:** `refactor(workspace_manager): merge WorkspaceProfile from models.py into workspace_manager.py` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule: WorkspaceProfile is only used by the workspace subsystem. MERGE.
+
+### Phase 3i: Merge MCP config classes into `src/mcp_client.py` (1 commit)
+
+- [x] **Task 3i.1** [Tier 3]: Add `MCPServerConfig`, `MCPConfiguration`, `VectorStoreConfig`, `RAGConfig` class definitions + `load_mcp_config` function to `src/mcp_client.py`
+  - HOW: `manual-slop_edit_file` to add the classes + function
+  - Source: copy from `src/models.py`
+  - Update imports in `src/models.py` (remove defs, add `from src.mcp_client import MCPServerConfig, MCPConfiguration, VectorStoreConfig, RAGConfig, load_mcp_config`)
+  - SAFETY: Run `tests/test_mcp_config.py` + `tests/test_mcp_client_*.py` + `tests/test_mcp_ts_integration.py`
+  - Per 4-criteria rule: C1=YES (mcp_client, api_hooks, app_controller), C3=YES (test_mcp_config.py), but MCP config classes are tightly coupled to MCP client. MERGE (they're the data layer of MCP).
+- [x] **COMMIT:** `refactor(mcp_client): merge MCP config dataclasses from models.py into mcp_client.py` (Tier 3)
+- [x] **GIT NOTE:** per the 4-criteria rule: MCP config classes are used by mcp_client + api_hooks + app_controller; the existing test file is `test_mcp_config.py` (not at the class level). MERGE because MCP config IS the MCP subsystem's data layer.
+
+## Phase 4: Delete `AGENT_TOOL_NAMES` (1 commit)
+
+- [x] **Task 4.1** [Tier 3]: Delete `AGENT_TOOL_NAMES` constant from `src/models.py` + update 8 consumer sites to use `mcp_tool_specs.tool_names()`
+  - Consumer sites: `src/app_controller.py:2110, 2972, 3273` (3 sites) + `tests/test_arch_boundary_phase2.py:23, 29, 31, 32, 33` (5 sites)
+  - HOW: `manual-slop_edit_file` per site
+  - Update test `test_tool_names_subset_of_models_agent_tool_names` — DELETE (it becomes a tautology) OR CONVERT to `assert mcp_tool_specs.tool_names() == {expected canonical tools}`
+  - SAFETY: Run the affected tests + the full batched suite
+- [x] **COMMIT:** `refactor(mcp_tool_specs): delete redundant AGENT_TOOL_NAMES; use tool_names() at consumer sites` (Tier 3)
+- [x] **GIT NOTE:** AGENT_TOOL_NAMES was a hardcoded snapshot of `mcp_tool_specs.tool_names()`. The existing test `test_tool_names_subset_of_models_agent_tool_names` literally asserts `tool_names() ⊆ AGENT_TOOL_NAMES`, proving the redundancy.
+
+## Phase 5: Reduce `src/models.py` to ~30 lines (1 commit)
+
+- [x] **Task 5.1** [Tier 3]: After Phases 3a-i, all 11 MMA Core + FileItem + Preset + Tool + ToolPreset + BiasProfile + TextEditorConfig + ExternalEditorConfig + Persona + WorkspaceProfile + MCPServerConfig + MCPConfiguration + VectorStoreConfig + RAGConfig + load_mcp_config + ProjectContext + 5 sub + _clean_nones + load_config_from_disk + save_config_to_disk + parse_history_entries + AGENT_TOOL_NAMES have been moved out of `src/models.py`
+  - `src/models.py` retains ONLY: `AGENT_TOOL_NAMES` (already deleted in Phase 4) + `DEFAULT_TOOL_CATEGORIES` + Pydantic proxies (`_create_generate_request`, `_create_confirm_request`, `__getattr__`)
+  - Target: ~30 lines (Pydantic proxies + `DEFAULT_TOOL_CATEGORIES` + docstring)
+  - HOW: `manual-slop_edit_file` to remove all the moved classes
+  - SAFETY: Run all affected tests + the full batched suite
+- [x] **COMMIT:** `refactor(models): reduce to Pydantic proxy helpers + DEFAULT_TOOL_CATEGORIES (~30 lines)` (Tier 3)

+
+## Notes for Tier 3 workers (v2 corrections)
+
+- **Tier 2 has ZERO discretion.** Every move is pre-decided in the spec. Do not make additional moves, do not create additional files, do not "improve" the plan.
+- **Do not move Pydantic proxies** (`_create_generate_request`, `_create_confirm_request`, `__getattr__`) from `src/models.py`. They are API-specific; moving them is OUT OF SCOPE for this track.
+- **Do not move `DEFAULT_TOOL_CATEGORIES`** from `src/models.py`. It is used by `app_controller.py`; moving it is out of scope.
+- **The 4-criteria rule is a CHECK before each move.** Apply it: if a class fails C1, C2, C3, and C4, the move is incorrect. STOP and report.
+- **Per-file atomic commits** — each move is a separate commit for atomic rollback.
+- **Preserve backward compat** — when removing a class from `models.py`, KEEP a `from src.<destination> import <class>` line in `models.py` for backward compat. Don't break existing imports.
+- **Style** — 1-space indentation, CRLF line endings, no comments, use `manual-slop_edit_file`.
+- **Per-phase regression-guard test runs** — after each phase, run the affected tests. If a phase causes a regression, REVERT the phase commit and investigate (don't try to fix forward).
+- **The `git stash*` ban is in effect** at 3 layers. Do not use `git stash` for any reason. If you need a "fresh start" feel, create a new branch.
+- **The timeline-is-immutable principle** — never use `git revert` / `git reset` / `git stash` to "undo" a bad commit. Write a forward corrective commit instead.
+
+## Notes for Tier 2 reviewer
+
+- **The track is now prescriptive.** v1 had gaps that gave Tier 2 discretion; v2 closes them. v2 should NOT require mid-execution corrections.
+- **Phase 0 resets the state.toml** — the 5 "damaged" tasks are reset to "pending" with a note explaining the data is intact.
+- **Phase 1 + 2 are DONE** — verify only, no code changes.
+- **Phase 3 is the main work** — 9 commits (3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i). Each commit is one of: create new file (3a, 3b, 3c) or merge into existing file (3d, 3e, 3f, 3g, 3h, 3i).
+- **Phase 4 deletes `AGENT_TOOL_NAMES`** — 1 commit, 8 consumer site updates.
+- **Phase 5 reduces `src/models.py`** — 1 commit.
+- **Phase 6 is verification** — 3 commits, no code changes.
+- **Total: 16 atomic commits** (down from v1's 22 because the tier 2 work is now prescriptive, not exploratory).

+# Track Specification: module_taxonomy_refactor_20260627
+
+## Overview
+
+The user-reported `models.py` is a "dumping ground" (1044 lines, 36 classes, 5+ unrelated domains). This track cleans it up PLUS addresses 5 ImGui LEAKS that violate the "ImGui belongs in `gui_2.py`" boundary PLUS unifies 2 vendor files with `ai_client.py`.
+
+Per the user's principle: **unify unless there's a good reason (import load times, definition pollution)**. No sub-directories. Prefix naming convention.
+
+## Current State Audit (master `5380b715`, measured 2026-06-27)
+
+| Metric | Value |
+|---|---:|
+| `src/` file count | 65 |
+| `src/models.py` line count | 1044 |
+| `src/models.py` class/function count | 36 |
+| `src/models.py` regions | 13 (Constants, Config Utilities, History Utilities, Pydantic Models, MMA Core, State & Config, Tool Models, UI/Editor, Persona, Workspace, MCP Config, Project Context, ...more) |
+| ImGui-using files outside `gui_2.py` | 5 (`bg_shader.py`, `shaders.py`, `command_palette.py`, `diff_viewer.py`, `patch_modal.py`) |
+| Vendor files separate from `ai_client.py` | 2 (`vendor_capabilities.py`, `vendor_state.py`) |
+| `AGENT_TOOL_NAMES` consumers | 8 (3 in `app_controller.py`, 5 in `tests/test_arch_boundary_phase2.py`) |
+| `mcp_tool_specs.tool_names()` test | EXISTS (asserts `tool_names() Γèå AGENT_TOOL_NAMES` ΓÇö proves it's redundant) |
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | **MERGE 5 ImGui LEAKS into `gui_2.py`** | `git grep -l "imgui_bundle\|from imgui\\." -- 'src/*.py'` returns ONLY `gui_2.py` + `imgui_scopes.py` |
+| G2 | **MERGE 2 vendor files into `ai_client.py`** | `ls src/{vendor_capabilities,vendor_state}.py` returns not-found; `python -c "from src.ai_client import ..."` imports the merged symbols |
+| G3 | **SPLIT `models.py`** into `mma.py` + `project.py` + `project_files.py` | `ls src/mma.py src/project.py src/project_files.py` all exist; `python -c "from src.mma import ThinkingSegment, Ticket, Track, WorkerContext, TrackState"` works |
+| G4 | **MERGE** 6+ other `models.py` classes into existing sub-system files | `Persona` in `personas.py`; `Tool`/`ToolPreset` in `tool_presets.py`; `BiasProfile` in `tool_bias.py`; `TextEditorConfig`/`ExternalEditorConfig` in `external_editor.py`; `MCPServerConfig`+etc in `mcp_client.py`; `WorkspaceProfile` in `workspace_manager.py` |
+| G5 | **DELETE `AGENT_TOOL_NAMES`** (redundant with `mcp_tool_specs.tool_names()`) | `git grep "AGENT_TOOL_NAMES" -- 'src/*.py'` returns 0 hits; 8 consumer sites updated to use `list(mcp_tool_specs.tool_names())` |
+| G6 | **`src/models.py` reduced to Γëñ30 lines** (or eliminated) | `wc -l src/models.py` returns Γëñ30 |
+| G7 | All 7 audit gates pass `--strict` | unchanged from baseline |
+| G8 | All batched test tiers pass (10/11 baseline + RAG flake) | unchanged from baseline |
+
+## Non-Goals
+
+- Renaming existing files for prefix consistency (`multi_agent_conductor.py` → `mma_conductor.py`, etc.) — deferred to follow-up; current names are clear enough
+- Refactoring `aggregate.py` (513 lines), `app_controller.py` (4869 lines), `gui_2.py` (7773 lines) ΓÇö out of scope; these have natural boundaries; the user doesn't want more splitting without good reason
+- Modifications to `mcp_client.py` other than merging the config dataclasses ΓÇö the merge itself is the change
+- New `src/<thing>.py` files (per AGENTS.md hard rule) ΓÇö the 3 new files (`mma.py`, `project.py`, `project_files.py`) are justified by the `models.py` split (definition pollution)
+
+## Functional Requirements
+
+### FR1: MERGE ImGui LEAKS into `gui_2.py`
+
+For each of these 5 files, move the content into `gui_2.py` in a clearly-marked section, then `git rm` the original:
+
+```python
+# In gui_2.py, add at the appropriate location:
+
+#region: Bg Shader (moved from src/bg_shader.py)
+# ... (content of src/bg_shader.py)
+#endregion
+
+#region: Shaders (moved from src/shaders.py)
+# ... (content of src/shaders.py)
+#endregion
+
+#region: Command Palette (moved from src/command_palette.py)
+# ... (content of src/command_palette.py)
+#endregion
+
+#region: Diff Viewer (moved from src/diff_viewer.py)
+# ... (content of src/diff_viewer.py)
+#endregion
+
+#region: Patch Modal (moved from src/patch_modal.py)
+# ... (content of src/patch_modal.py)
+#endregion
+```
+
+**Imports to update across the codebase:**
+- `from src.bg_shader import X` → `from src.gui_2 import X`
+- `from src.shaders import X` → `from src.gui_2 import X`
+- (etc. for all 5 files)
+
+### FR2: MERGE vendor files into `ai_client.py`
+
+```python
+# In ai_client.py, add at the appropriate location:
+
+#region: Vendor Capabilities (moved from src/vendor_capabilities.py)
+# ... (content of src/vendor_capabilities.py)
+#endregion
+
+#region: Vendor State (moved from src/vendor_state.py)
+# ... (content of src/vendor_state.py)
+#endregion
+```
+
+**Imports to update:**
+- `from src.vendor_capabilities import X` → `from src.ai_client import X`
+- `from src.vendor_state import X` → `from src.ai_client import X`
+
+### FR3: SPLIT `models.py`
+
+**Phase 1: Create `src/mma.py`** with the MMA Core + TrackState:
+- ThinkingSegment
+- Ticket
+- Track
+- WorkerContext
+- TrackState
+- Top-level docstring explaining MMA scope
+
+**Phase 2: Create `src/project.py`** with the project config:
+- ProjectContext + 5 sub-dataclasses (ProjectMeta, ProjectOutput, ProjectFiles, ProjectScreenshots, ProjectDiscussion)
+- Config I/O helpers: `_clean_nones`, `load_config_from_disk`, `save_config_to_disk`, `parse_history_entries`
+- Top-level docstring explaining project config scope
+
+**Phase 3: Create `src/project_files.py`** with the file-related dataclasses:
+- FileItem
+- ContextPreset
+- ContextFileEntry
+- NamedViewPreset
+- Preset
+- Top-level docstring explaining file-related project state scope
+
+### FR4: MERGE other `models.py` classes into existing sub-system files
+
+| Class from `models.py` | Destination (existing file) | New section name |
+|---|---|---|
+| `Persona` | `src/personas.py` | "Persona Dataclass" |
+| `Tool`, `ToolPreset` | `src/tool_presets.py` | "Tool + ToolPreset Dataclasses" |
+| `BiasProfile` | `src/tool_bias.py` | "BiasProfile Dataclass" |
+| `TextEditorConfig`, `ExternalEditorConfig` | `src/external_editor.py` | "Editor Config Dataclasses" |
+| `MCPServerConfig`, `MCPConfiguration`, `VectorStoreConfig`, `RAGConfig`, `load_mcp_config` | `src/mcp_client.py` | "MCP Config Dataclasses" |
+| `WorkspaceProfile` | `src/workspace_manager.py` | "WorkspaceProfile Dataclass" |
+
+### FR5: DELETE `AGENT_TOOL_NAMES` (redundant)
+
+```python
+# 8 consumer site updates:
+# Before:
+from src.models import AGENT_TOOL_NAMES
+for tool in AGENT_TOOL_NAMES:
+    ...
+
+# After:
+from src import mcp_tool_specs
+for tool in mcp_tool_specs.tool_names():
+    ...
+```
+
+**Consumer sites (8):**
+- `src/app_controller.py:2110, 2972, 3273` (3 sites)
+- `tests/test_arch_boundary_phase2.py:23, 29, 31, 32, 33` (5 sites)
+
+**Test simplification:** `test_tool_names_subset_of_models_agent_tool_names` becomes either:
+- DELETE (it's a tautology once `AGENT_TOOL_NAMES` is derived from `tool_names()`)
+- OR convert to a positive assertion: `assert mcp_tool_specs.tool_names() == {expected canonical tools}`
+
+### FR6: REDUCE `src/models.py` to ~30 lines (or eliminate)
+
+After all moves, `src/models.py` contains:
+- `_create_generate_request`, `_create_confirm_request`, `__getattr__` (Pydantic lazy proxies for the API)
+- OR these move to `src/api_hooks.py` (if API-specific)
+- Top-level docstring
+
+If `models.py` becomes essentially empty after these moves, **delete the file entirely** (it's not a "system" file; `models.py` is just a temporary holder).
+
+## Non-Functional Requirements
+
+- NFR1: 1-space indentation (per `conductor/workflow.md`)
+- NFR2: CRLF line endings on Windows
+- NFR3: No comments in source code (per AGENTS.md "No comments in source code")
+- NFR4: Per-task atomic commits with git notes
+- NFR5: No new pip dependencies
+- NFR6: `Result[T]` returns for fallible fns (per `error_handling.md`)
+- NFR7: No new `src/<thing>.py` files UNLESS justified by definition pollution (per AGENTS.md hard rule)
+
+## Architecture Reference
+
+- `AGENTS.md` ΓÇö "File Size and Naming Convention" HARD RULE
+- `conductor/code_styleguides/data_oriented_design.md` ΓÇö "Prefer Fewer Types" principle
+- `conductor/code_styleguides/error_handling.md` ΓÇö the `Result[T]` convention
+- `conductor/code_styleguides/type_aliases.md` ΓÇö the 10 TypeAliases convention
+- `conductor/tracks/cruft_elimination_20260627/SPEC_CORRECTION_phase_2.md` ΓÇö the related spec correction (the original Phase 2 spec was wrong to put ProjectContext in `models.py`; this track fixes that)
+- `docs/reports/FOLLOWUP_module_taxonomy_20260627.md` ΓÇö the previous followup report (this track supersedes it with concrete execution)
+
+## Out of Scope
+
+- Renaming existing files for prefix consistency (`multi_agent_conductor.py` → `mma_conductor.py`, etc.) — deferred to follow-up
+- Refactoring `aggregate.py` (513 lines), `app_controller.py` (4869 lines), `gui_2.py` (7773 lines) ΓÇö out of scope; these have natural boundaries
+- Modifications to `mcp_client.py` other than merging the config dataclasses
+- New `src/<thing>.py` files beyond the 3 justified ones (`mma.py`, `project.py`, `project_files.py`)
+- The RAG test pre-existing flake (per `docs/reports/SSDL_CAMPAIGN_ABORTED_20260624.md` "Out of Scope")
+- Any Tier 2 spec rewrites (per the user's earlier "don't fuck with commits" directive)
+
+## Verification Criteria (Definition of Done)
+
+| # | Criterion | Verification |
+|---|---|---|
+| VC1 | ImGui imports limited to `gui_2.py` + `imgui_scopes.py` | `git grep -l "imgui_bundle\|from imgui\\." -- 'src/*.py'` returns 2 files |
+| VC2 | `src/bg_shader.py`, `src/shaders.py`, `src/command_palette.py`, `src/diff_viewer.py` deleted (4 LEAK files per the data/view/ops split) | `ls src/{bg_shader,shaders,command_palette,diff_viewer}.py` returns not-found. `src/patch_modal.py` is NOT a LEAK ΓÇö it's the data module (DiffHunk/DiffFile/PendingPatch) per the data/view/ops split rule. The diff_viewer classes (DiffHunk/DiffFile) were moved INTO it during the cruft_elimination track's split; deleting it would violate the data module's integrity. See `conductor/tracks/post_module_taxonomy_de_cruft_20260627/spec.md` Phase 1 for the formal correction. |
+| VC3 | `src/vendor_capabilities.py`, `src/vendor_state.py` deleted | `ls src/{vendor_capabilities,vendor_state}.py` returns not-found |
+| VC4 | Vendor symbols importable from `src.ai_client` | `python -c "from src.ai_client import PROVIDER_CAPABILITIES, get_vendor_state"` works |
+| VC5 | `src/mma.py` exists with MMA Core + TrackState | `python -c "from src.mma import ThinkingSegment, Ticket, Track, WorkerContext, TrackState"` works |
+| VC6 | `src/project.py` exists with ProjectContext + sub + config I/O | `python -c "from src.project import ProjectContext, ProjectMeta, ProjectOutput, ProjectFiles, ProjectScreenshots, ProjectDiscussion, _clean_nones, load_config_from_disk, save_config_to_disk, parse_history_entries"` works |
+| VC7 | `src/project_files.py` exists with file-related dataclasses | `python -c "from src.project_files import FileItem, ContextPreset, ContextFileEntry, NamedViewPreset, Preset"` works |
+| VC8 | Persona/Tool/Editor/MCP/Workspace dataclasses in their proper sub-system files | `python -c "from src.personas import Persona; from src.tool_presets import Tool, ToolPreset; from src.tool_bias import BiasProfile; from src.external_editor import TextEditorConfig, ExternalEditorConfig; from src.mcp_client import MCPServerConfig, MCPConfiguration, VectorStoreConfig, RAGConfig, load_mcp_config; from src.workspace_manager import WorkspaceProfile"` works |
+| VC9 | `AGENT_TOOL_NAMES` deleted; all 8 consumer sites use `mcp_tool_specs.tool_names()` | `git grep "AGENT_TOOL_NAMES" -- 'src/*.py' 'tests/*.py'` returns 0 hits |
+| VC10 | `src/models.py` reduced from 1044 to ~135 lines (Pydantic proxies + DEFAULT_TOOL_CATEGORIES + lazy `__getattr__` for backward compat) | `wc -l src/models.py` returns Γëñ200; the 30-line target was aspirational. The lazy `__getattr__` is necessary for backward compat with 30+ legacy `from src.models import X` call sites until the `post_module_taxonomy_de_cruft_20260627` follow-up track migrates them to direct imports from the subsystem files (`src.mma`, `src.project`, `src/project_files`, `src/tool_presets`, `src/tool_bias`, `src/external_editor`, `src/personas`, `src/workspace_manager`, `src/mcp_client`). The full migration is FR7 of the post_module_taxonomy_de_cruft_20260627 track. The legacy `Metadata = TrackMetadata` alias is preserved for `from src.models import Metadata` to resolve to the TrackMetadata dataclass (used by `tests/test_track_state_schema.py`). |
+| VC11 | All 7 audit gates pass `--strict` | unchanged from baseline |
+| VC12 | 10/11 batched test tiers pass (RAG flake acceptable) | unchanged from baseline |
+
+## Risks
+
+| # | Risk | Likelihood | Mitigation |
+|---|---|---|---|
+| R1 | ImGui LEAKS move breaks existing tests (e.g., `command_palette` is referenced in commands.py) | low | Run full affected test set after each move; revert + fix on regression |
+| R2 | Vendor merge into `ai_client.py` creates circular imports (PROVIDERS lazy proxy is the workaround) | medium | The lazy import pattern (`__getattr__`) handles this; verify by running the full test suite after merge |
+| R3 | `models.py` split breaks 136 import sites | high | Per-file move with regression-guard tests after each; update imports systematically |
+| R4 | The 6+ "merge into existing sub-system files" moves break those files' existing tests | medium | Run the affected test file after each merge |
+| R5 | `AGENT_TOOL_NAMES` deletion breaks `test_arch_boundary_phase2.py` | low | Update the test to use `mcp_tool_specs.tool_names()`; cross-check that the test's expected tool names are in the registry |
+| R6 | The `ProjectContext` Phase 2 commit (in `cruft_elimination_20260627`) put `ProjectContext` in `models.py`; the new track moves it to `project.py` ΓÇö needs to coordinate with the cruft track | high | The cruft track should NOT merge its `models.py` `ProjectContext` commit; this refactor track handles the move |
+| R7 | The `_create_generate_request` etc. Pydantic proxies in `models.py` are used by `api_hooks.py`; if we move them to `api_hooks.py` we create a different topology | low | Audit the consumers; if they're all in `api_hooks.py`, move them; if not, keep in `models.py` or move to a new `api_models.py` |

+# Tier 2 Startup Brief: post_module_taxonomy_de_cruft_20260627
+
+## Context
+
+Followup to module_taxonomy_refactor_20260627 (v2). After the taxonomy is settled, clean up the remaining cruft that v2 was explicitly out-of-scope for. Two critical bugs from v2 must be fixed first; then 4 de-cruft tasks address the __getattr__ shim, DEFAULT_TOOL_CATEGORIES, Pydantic proxies, and ImGui usage standardization.
+
+## MANDATORY Pre-Action Reading (per agent protocol)
+
+1. AGENTS.md (operating rules, especially "File Size and Naming Convention" HARD RULE)
+2. conductor/workflow.md (the workflow)
+3. conductor/edit_workflow.md (the edit workflow)
+4. conductor/code_styleguides/data_oriented_design.md (Prefer Fewer Types principle)
+5. conductor/code_styleguides/error_handling.md (Result[T] convention)
+6. conductor/code_styleguides/type_aliases.md (the 10 TypeAliases convention)
+7. conductor/code_styleguides/code_path_audit.md (code path audit styleguide)
+8. **conductor/tracks/post_module_taxonomy_de_cruft_20260627/spec.md** (the canonical reference for this plan)
+9. **conductor/tracks/post_module_taxonomy_de_cruft_20260627/plan.md** (the 6-phase plan; 12 atomic commits)
+10. conductor/tracks/module_taxonomy_refactor_20260627/spec.md (the v2 spec that this track follows up on)
+11. docs/reports/FOLLOWUP_module_taxonomy_v2_review.md (the review that identified these tasks)
+12. docs/reports/FOLLOWUP_module_taxonomy_refactor_20260627_recoverable.md (the recovery report)
+
+**First commit of this track must include** `TIER-2 READ <list> before post_module_taxonomy_de_cruft_20260627` in the message.
+
+## TIMELINE-IS-IMMUTABLE PRINCIPLE (added 2026-06-27 per user feedback)
+
+When you (the agent) fuck up — make a wrong commit, break a file, take a bad path — your first instinct will be to "undo" the mistake with `git revert`, `git reset`, or `git stash`. **THIS INSTINCT IS WRONG.** The user explicitly stated: "if an agent fucks up, their tendency to want to 'revert' is not correct and instead they must live with the timeline and just do corrections with a new commit."
+
+**The rule:**
+- The git history is IMMUTABLE on this branch. Every commit you've made is part of the record.
+- "Fixing forward" via a new commit makes the user's review EASIER.
+- "Undoing" via `git revert` / `git reset` / `git stash` makes the user's review HARDER (they have to read the diff between the bad and the "fix" to understand what went wrong).
+
+**Correct pattern when you fuck up:**
+1. Pause. Read the actual file. Confirm the state.
+2. Write a NEW commit that fixes the problem. The commit message should briefly say what was wrong and what you fixed.
+3. If the bad commit introduced data corruption that the user will see, the user can `git revert` it during their review — that's the user's choice, not yours.
+4. If you need to recover an old version of a file, use `git show <good-sha>:<path> > <path>` to extract it.
+
+**Wrong pattern (which you must NOT do):**
+- `git revert <sha>` to undo a commit
+- `git reset --hard <sha>` to throw away a bad commit
+- `git stash` to "save" uncommitted work
+- `git checkout <old-sha> -- .` to "go back to when things were good" (and then commit on top)
+
+## HARD BAN: `git stash*` (added 2026-06-27)
+
+`git stash`, `git stash pop`, `git stash apply`, `git stash drop`, `git stash clear` are FORBIDDEN at 3 layers:
+1. AGENTS.md HARD BAN
+2. conductor/tier2/opencode.json.fragment bash deny rules (top-level + agent-level)
+3. This prompt's Hard Bans list
+
+Stashing throws away the user's in-progress edits silently. If you think you need a stash, you don't — use a NEW BRANCH or a WORKTREE instead.

+
+## Per-phase patterns for Tier 3 workers
+
+### Pattern: fix critical bug (Phase 0)
+
+```bash
+# 1. Find the original definition
+git log -p --all -S "LEGACY_NAMES" -- scripts/generate_type_registry.py
+
+# 2. Add the missing definition (or remove the reference)
+# manual-slop_edit_file scripts/generate_type_registry.py
+# Add LEGACY_NAMES = [...] at the top of the file
+
+# 3. Verify
+uv run python scripts/generate_type_registry.py --check
+```
+
+### Pattern: create symlink (Phase 0)
+
+```bash
+# 1. Find the most recent audit output
+ls docs/reports/code_path_audit/
+
+# 2. Create the symlink
+New-Item -ItemType SymbolicLink -Path docs/reports/code_path_audit/latest -Target <most-recent>
+
+# 3. Verify
+uv run python scripts/audit_code_path_audit_coverage.py --input-dir docs/reports/code_path_audit/latest --strict
+```
+
+### Pattern: remove __getattr__ shim (Phase 2)
+
+```bash
+# 1. Find all consumer sites
+git grep "from src.models import" -- 'src/*.py' 'tests/*.py'
+
+# 2. Update each consumer to use direct imports
+# For MMA Core classes (Ticket, Track, etc.):
+#   from src.models import Ticket
+#   ->
+#   from src.mma import Ticket
+# For ProjectContext:
+#   from src.models import ProjectContext
+#   ->
+#   from src.project import ProjectContext
+# For FileItem + Preset + ContextPreset + ContextFileEntry + NamedViewPreset:
+#   from src.models import FileItem
+#   ->
+#   from src.project_files import FileItem
+# For Tool + ToolPreset:
+#   from src.models import Tool
+#   ->
+#   from src.tool_presets import Tool
+# For BiasProfile:
+#   from src.models import BiasProfile
+#   ->
+#   from src.tool_bias import BiasProfile
+# For TextEditorConfig + ExternalEditorConfig:
+#   from src.models import TextEditorConfig
+#   ->
+#   from src.external_editor import TextEditorConfig
+# For Persona:
+#   from src.models import Persona
+#   ->
+#   from src.personas import Persona
+# For WorkspaceProfile:
+#   from src.models import WorkspaceProfile
+#   ->
+#   from src.workspace_manager import WorkspaceProfile
+# For MCPServerConfig + MCPConfiguration + VectorStoreConfig + RAGConfig + load_mcp_config:
+#   from src.models import MCPServerConfig
+#   ->
+#   from src.mcp_client import MCPServerConfig
+
+# 3. Remove the __getattr__ shim from src/models.py
+# manual-slop_edit_file src/models.py
+# Delete the entire __getattr__ function
+
+# 4. Verify
+uv run python -m pytest tests/test_*.py -v
+```
+
+### Pattern: move dict/constant (Phase 3, Phase 4)
+
+```bash
+# 1. Add the dict/constant to the destination file
+# manual-slop_edit_file src/ai_client.py
+# Add DEFAULT_TOOL_CATEGORIES = { ... } in the right location
+
+# 2. Remove from the source file
+# manual-slop_edit_file src/models.py
+# Delete the DEFAULT_TOOL_CATEGORIES definition
+
+# 3. Update consumer sites
+# git grep DEFAULT_TOOL_CATEGORIES -- 'src/*.py'
+# Update each consumer to import from the new location
+
+# 4. Verify
+uv run python -m pytest tests/test_app_controller_*.py -v
+```
+
+### Pattern: standardize ImGui usage (Phase 5)
+
+```bash
+# For each of the 4 files (markdown_helper.py, theme_2.py, theme_nerv.py, theme_nerv_fx.py):
+
+# 1. Find ImGui begin_/end_ pairs
+git grep "imgui\." src/markdown_helper.py
+# Look for: imgui.begin("X") ... imgui.end()
+
+# 2. Replace with imgui_scopes.py context manager pattern
+# manual-slop_edit_file src/markdown_helper.py
+# Replace:
+#   imgui.begin("X")
+#   # content
+#   imgui.end()
+# With:
+#   with imgui.begin("X"):
+#       # content
+
+# 3. Add the import
+# from src.imgui_scopes import ...
+
+# 4. Verify
+uv run python -m pytest tests/test_<file>.py -v
+```
+
+### Style
+
+- 1-space indentation (project standard)
+- CRLF line endings
+- No comments in source code (per AGENTS.md)
+- Use manual-slop_edit_file for surgical edits
+- Per-phase regression-guard test runs after each phase
+- Preserve backward-compat: when removing a class from models.py, KEEP a re-export line for any consumer that still uses the old path
+
+## Notes for Tier 2 reviewer
+
+- **Phase 0 is critical** — these are bugs Tier 2 introduced in v2. Fix them FIRST.
+- **Phase 1 is the spec update** (VC2 + VC10 corrections). The user's acceptance of the trade-offs is documented.
+- **Phase 2 is the most invasive** — removing the __getattr__ shim changes the import surface for 30+ consumer sites. Run the full batched test suite after each consumer-site update.
+- **Phase 3 + 4 are simple moves** — single-consumer moves. Verify after each.
+- **Phase 5 is per-file** — 4 commits, 1 per file. Verify after each.
+- **Total: 12 atomic commits** (matches the spec's expected commit count).
+- **Tier 2 must NOT use `git stash*` for any reason.** Banned at 3 layers.
+- **Tier 2 must NOT use `git revert*` / `git reset*` for any reason.** Banned per AGENTS.md. Use forward commits instead.

+# Plan: post_module_taxonomy_de_cruft_20260627
+
+5 phases, 11 tasks, ~12 atomic commits. Per-task TDD red-first. Tier 3 workers execute; Tier 2 reviews per phase.
+
+## Phase 0: Fix critical bugs (Tier 3, 2 commits)
+
+**Focus:** The 2 critical bugs that broke the audit gates. Must be fixed FIRST before the de-cruft work can proceed.
+
+- [x] **Task 0.1** [Tier 3]: Fix the `NameError: LEGACY_NAMES` bug in `scripts/generate_type_registry.py`
+  - HOW: `git log -p --all -S "LEGACY_NAMES" -- scripts/generate_type_registry.py` to find the original definition
+  - Add the missing definition or remove the reference
+  - SAFETY: `uv run python scripts/generate_type_registry.py --check` exits 0
+- [x] **COMMIT 0.1:** `fix(generate_type_registry): define LEGACY_NAMES to fix NameError` (Tier 3)
+- [x] **GIT NOTE:** Tier 2 introduced this bug in their v2 work. Re-ran `git log -p --all -S "LEGACY_NAMES"` to find the original definition and restored it.
+
+- [x] **Task 0.2** [Tier 3]: Create the `latest` symlink for `audit_code_path_audit_coverage.py`
+  - HOW: `New-Item -ItemType SymbolicLink -Path docs/reports/code_path_audit/latest -Target <most-recent>`
+  - Most recent: identify via `ls docs/reports/code_path_audit/ | Sort-Object | Select-Object -Last 1`
+  - SAFETY: `uv run python scripts/audit_code_path_audit_coverage.py --input-dir docs/reports/code_path_audit/latest --strict` exits 0
+- [x] **COMMIT 0.2:** `fix(audit): create docs/reports/code_path_audit/latest symlink` (Tier 3)
+- [x] **GIT NOTE:** Tier 2 ran the type registry regeneration but didn't create the symlink. This fixes the audit gate.
+
+## Phase 1: Update v2 spec (Tier 1, 1 commit)
+
+**Focus:** The 2 spec corrections (VC2 patch_modal.py as data module; VC10 162-line trade-off).
+
+- [x] **Task 1.1** [Tier 1]: Edit `conductor/tracks/module_taxonomy_refactor_20260627/spec.md` to update VC2 and VC10
+  - VC2: add note that patch_modal.py is a data module (DiffHunk, DiffFile, PendingPatch) per data/view/ops split
+  - VC10: accept 162-line models.py as the trade-off for backward compat (the 30-line target was unrealistic)
+- [x] **COMMIT 1.1:** `docs(spec): correct VC2 + VC10 in module_taxonomy_refactor_20260627 spec` (Tier 1)
+- [x] **GIT NOTE:** v2 spec corrections per `FOLLOWUP_module_taxonomy_v2_review`. VC2 now acknowledges patch_modal.py as a data module. VC10 now accepts 162-line models.py as the backward-compat trade-off.
+
+## Phase 2: Remove `__getattr__` shim from `models.py` (Tier 3, 1-2 commits)
+
+**Focus:** The biggest de-cruft task. The `__getattr__` shim preserves backward compat for 30+ legacy imports. Removing it requires updating those imports.
+
+- [x] **Task 2.1** [Tier 3]: Inventory all `from src.models import X` for the moved classes (Ticket, Track, WorkerContext, TrackState, TrackMetadata, ThinkingSegment, ProjectContext, FileItem, Preset, ContextPreset, ContextFileEntry, NamedViewPreset, Tool, ToolPreset, BiasProfile, TextEditorConfig, ExternalEditorConfig, Persona, WorkspaceProfile, MCPServerConfig, MCPConfiguration, VectorStoreConfig, RAGConfig, load_mcp_config, Persona, etc.)
+  - HOW: `git grep "from src.models import" -- 'src/*.py' 'tests/*.py'`
+- [x] **Task 2.2** [Tier 3]: Update consumer sites to use direct imports (per class, migrate to the right subsystem file)
+  - MMA Core: `from src.mma import ...`
+  - ProjectContext: `from src.project import ...`
+  - FileItem + Preset + ContextPreset + etc: `from src.project_files import ...`
+  - Tool + ToolPreset: `from src.tool_presets import ...`
+  - BiasProfile: `from src.tool_bias import ...`
+  - TextEditorConfig + ExternalEditorConfig: `from src.external_editor import ...`
+  - Persona: `from src.personas import ...`
+  - WorkspaceProfile: `from src.workspace_manager import ...`
+  - MCP config: `from src.mcp_client import ...`
+- [x] **Task 2.3** [Tier 3]: Remove the `__getattr__` shim from `src/models.py`
+  - HOW: `manual-slop_edit_file` to remove the function
+  - SAFETY: `uv run python -m pytest tests/test_*.py -v` to verify no consumer broke
+- [x] **COMMIT 2.1:** `refactor(models): remove __getattr__ shim; 30+ consumer sites now use direct imports` (Tier 3)
+- [x] **GIT NOTE:** After migration, `from src.models import X` for moved classes raises `ImportError`. The legacy compat shim is no longer needed.
+
+## Phase 3: Move `DEFAULT_TOOL_CATEGORIES` to `src/ai_client.py` (Tier 3, 1 commit)
+
+**Focus:** A single dict moves; single consumer (app_controller.py).
+
+- [x] **Task 3.1** [Tier 3]: Move `DEFAULT_TOOL_CATEGORIES` from `src/models.py` to `src/ai_client.py`
+  - HOW: `manual-slop_edit_file` to add the dict to `src/ai_client.py`; remove from `src/models.py`
+  - Update consumer: `src/app_controller.py` to `from src.ai_client import DEFAULT_TOOL_CATEGORIES`
+  - SAFETY: `uv run python -m pytest tests/test_app_controller_*.py -v`
+- [x] **COMMIT 3.1:** `refactor(ai_client): move DEFAULT_TOOL_CATEGORIES from models.py to ai_client.py` (Tier 3)
+- [x] **GIT NOTE:** `DEFAULT_TOOL_CATEGORIES` is a categorization of MCP tools; the AI client is the natural owner. Single consumer (app_controller.py).
+
+## Phase 4: Move Pydantic proxies to `src/api_hooks.py` (Tier 3, 1 commit)
+
+**Focus:** The Pydantic proxies (`_create_generate_request`, `_create_confirm_request`, the Pydantic-specific `__getattr__`) are API-specific.
+
+- [x] **Task 4.1** [Tier 3]: Move the Pydantic proxies from `src/models.py` to `src/api_hooks.py`
+  - HOW: `manual-slop_edit_file` to add the proxies to `src/api_hooks.py`; remove from `src/models.py`
+  - Update consumer sites: `src/api_hooks.py` (uses the proxies to create the request models); `src/api_hook_client.py` (uses for client-side validation)
+  - SAFETY: `uv run python -m pytest tests/test_api_hooks*.py tests/test_api_hook_client*.py -v`
+- [x] **COMMIT 4.1:** `refactor(api_hooks): move Pydantic proxies from models.py to api_hooks.py` (Tier 3)
+- [x] **GIT NOTE:** Pydantic proxies are API-specific; they belong with `api_hooks.py`. 2 consumer sites updated.
+
+## Phase 5: Standardize ImGui usage (Tier 3, 1 commit per file = 4 commits)
+
+**Focus:** The 4 files that use ImGui directly (not through `imgui_scopes.py` context managers).
+
+- [x] **Task 5.1** [Tier 3]: Refactor `src/markdown_helper.py` to use `imgui_scopes.py` context managers
+- [x] **Task 5.2** [Tier 3]: Refactor `src/theme_2.py` to use `imgui_scopes.py` context managers
+- [x] **Task 5.3** [Tier 3]: Refactor `src/theme_nerv.py` to use `imgui_scopes.py` context managers
+- [x] **Task 5.4** [Tier 3]: Refactor `src/theme_nerv_fx.py` to use `imgui_scopes.py` context managers
+- [x] **COMMITS 5.1-5.4:** One per file
+
+## Phase 6: Verification (Tier 2, 1-2 commits)
+
+- [x] **Task 6.1** [Tier 2]: Run all 13 VCs
+  - VC1: generate_type_registry.py --check exits 0
+  - VC2: audit_code_path_audit_coverage.py --input-dir docs/reports/code_path_audit/latest --strict exits 0

+  - VC9: src/models.py reduced to <=20 lines
+  - VC10: All consumer sites updated to direct imports
+  - VC11: v2 spec updated
+  - VC12: All 7 audit gates pass --strict (re-verify)
+  - VC13: 10/11 batched test tiers pass (re-verify)
+  - Document in `docs/reports/TRACK_COMPLETION_post_module_taxonomy_de_cruft_20260627.md`
+- [x] **COMMIT 6.1:** `conductor(state): post_module_taxonomy_de_cruft_20260627 SHIPPED` (Tier 2)
+- [x] **COMMIT 6.2:** `docs(reports): TRACK_COMPLETION_post_module_taxonomy_de_cruft_20260627` (Tier 2)

+
+## Notes for Tier 3 workers
+
+- **Phase 0 is critical** — these are bugs Tier 2 introduced. Fix them FIRST.
+- **Phase 2 (remove `__getattr__` shim) is the biggest task** — there are 30+ consumer sites. Use `git grep` to find them all. Update them per the migration pattern.
+- **Phase 5 (ImGui standardization) is per-file** — 4 commits, 1 per file. Each file has its own tests; verify after each.
+- **Style** — 1-space indentation, CRLF line endings, no comments, use `manual-slop_edit_file`.
+- **Per-phase regression-guard test runs** — after each phase, run the affected tests. If a phase causes a regression, REVERT the phase commit and investigate (don't try to fix forward).
+- **The `git stash*` ban is in effect** at 3 layers. Do not use `git stash` for any reason. If you need a "fresh start" feel, create a new branch.
+- **The timeline-is-immutable principle** — never use `git revert` / `git reset` / `git stash` to "undo" a bad commit. Write a forward corrective commit instead.
+- **Phase 1 (spec update) is by Tier 1** — Tier 3 should NOT modify the v2 spec. The Tier 1 update reflects the user's acceptance of the trade-offs.
+
+## Notes for Tier 2 reviewer
+
+- **The 2 critical bugs in Phase 0 are the priority** — they broke the audit gates. Fix them FIRST.
+- **The v2 spec update in Phase 1** is by Tier 1. Tier 2 should NOT modify the spec.
+- **Phase 2 is the most invasive** — removing the `__getattr__` shim changes the import surface for 30+ consumer sites. Run the full batched test suite after each consumer-site update.
+- **Phase 5 (ImGui standardization) is per-file** — 4 commits, 1 per file. Verify after each.
+- **Total: 12 atomic commits** (matches the spec's expected commit count).

+# Track Specification: post_module_taxonomy_de_cruft_20260627
+
+## Overview
+
+Followup to module_taxonomy_refactor_20260627. After the taxonomy is settled, clean up the remaining cruft that v2 was explicitly out-of-scope for. Two critical bugs from v2 must be fixed first; then 4 de-cruft tasks address the __getattr__ shim, DEFAULT_TOOL_CATEGORIES, Pydantic proxies, and the patch_modal.py data module issue.
+
+## Current State Audit (master 6344b49f, measured 2026-06-27)
+
+| Metric | Value | Source |
+|---|---:|---|
+| src/models.py line count | 162 | wc -l src/models.py (spec target was 30) |
+| LEGACY_NAMES in generate_type_registry.py | BROKEN | LEGACY_NAMES referenced but not defined (Tier 2 introduced this bug) |
+| docs/reports/code_path_audit/latest symlink | MISSING | required by audit_code_path_audit_coverage.py |
+| patch_modal.py | 115 lines, EXISTS | data module (DiffHunk, DiffFile, PendingPatch) per data/view/ops split; spec was wrong to require deletion |
+| src/models.py content | __getattr__ shim + DEFAULT_TOOL_CATEGORIES + Pydantic proxies | still has cruft |
+| v2 audit gates | 5/7 pass | 2 broken (NameError + missing symlink) |
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | Fix the NameError: LEGACY_NAMES bug in generate_type_registry.py | generate_type_registry.py --check exits 0 |
+| G2 | Create the latest symlink for audit_code_path_audit_coverage.py | audit_code_path_audit_coverage.py --input-dir docs/reports/code_path_audit/latest --strict exits 0 |
+| G3 | Update VC2 in the v2 spec to acknowledge patch_modal.py is a data module (not a LEAK) | spec.md reflects the data module status |
+| G4 | Update VC10 in the v2 spec to accept 162-line models.py (backward compat trade-off) | spec.md reflects the trade-off |
+| G5 | All 7 audit gates pass --strict | Same as v2 baseline |
+| G6 | 10/11 batched test tiers pass (RAG flake acceptable) | Same as v2 baseline |
+| G7 | Remove the __getattr__ shim from src/models.py as consumers migrate to direct imports | __getattr__ function removed; 30+ consumer sites updated |
+| G8 | Move DEFAULT_TOOL_CATEGORIES to src/ai_client.py | DEFAULT_TOOL_CATEGORIES removed from src/models.py; from src.ai_client import DEFAULT_TOOL_CATEGORIES works |
+| G9 | Move Pydantic proxies to src/api_hooks.py | _create_generate_request, _create_confirm_request moved; from src.api_hooks import GenerateRequest, ConfirmRequest works |
+| G10 | Refactor ImGui usage in markdown_helper.py, theme_2.py, theme_nerv.py, theme_nerv_fx.py to use the imgui_scopes.py context manager pattern uniformly | All imgui.begin_/imgui.end_ calls go through imgui_scopes.py |
+| G11 | src/models.py reduced to 20 lines (just docstring + imports) | After G7+G8+G9, models.py is essentially empty |
+
+## Non-Goals
+
+- The 4-criteria rule itself (established in v2)
+- The data/view/ops split (established in v2)
+- The __getattr__ legacy migration shim back from subsystem files (the shim is being REMOVED)
+- Refactoring aggregate.py (513 lines), app_controller.py (4869 lines), gui_2.py (7773 lines)
+- The RAG test pre-existing flake
+- The v2 spec rewriting (it was a track artifact, not a commit in the v2 branch)
+
+## Functional Requirements
+
+### FR1: Fix the NameError: LEGACY_NAMES bug
+
+The bug is in scripts/generate_type_registry.py. The LEGACY_NAMES variable is referenced but not defined. The fix is to either:
+- Define the variable before it's referenced
+- Remove the reference if it's not needed
+- Import it from the correct module
+
+**Action:**
+1. Use git log -p --all -S LEGACY_NAMES to find the original definition
+2. Add the missing definition or remove the reference
+3. Re-run generate_type_registry.py --check to verify
+
+### FR2: Create the latest symlink
+
+The audit_code_path_audit_coverage.py script expects a latest symlink in docs/reports/code_path_audit/. The symlink should point to the most recent audit output (e.g., 2026-06-22).
+
+**Action:**
+1. Identify the most recent audit output directory
+2. Create the symlink pointing to the most recent
+3. Re-run audit_code_path_audit_coverage.py --input-dir docs/reports/code_path_audit/latest --strict
+
+### FR3: Update VC2 in the v2 spec
+
+The current VC2 says 5 ImGui LEAK files deleted. The v2 spec didn't account for patch_modal.py being a data module. Update VC2 to acknowledge that patch_modal.py is a data module, not a LEAK.
+
+**Action:** edit the v2 spec to update the VC2 line to:
+
+```
+VC2: 4 ImGui LEAK files deleted (bg_shader, shaders, command_palette, diff_viewer).
+patch_modal.py is NOT a LEAK — it's a data module (DiffHunk/DiffFile/PendingPatch)
+per the data/view/ops split rule. The diff_viewer classes were moved INTO it
+during the cruft_elimination track's split; deleting it would violate the
+data module's integrity.
+```
+
+### FR4: Update VC10 in the v2 spec
+
+The current VC10 says src/models.py reduced to 30 lines. Tier 2 hit 162 lines because of backward compat. Update VC10 to accept the trade-off.
+
+**Action:** edit the spec to:
+
+```
+VC10: src/models.py reduced from 1044 to 200 lines (achieves backward compat
+for 30+ legacy imports via __getattr__ lazy-load shim). The 30-line target
+was unrealistic given the legacy import surface; 162 lines is the accepted
+trade-off. Full migration to direct imports is FR7 in the
+post_module_taxonomy_de_cruft_20260627 follow-up track.
+```
+
+### FR5: Remove the __getattr__ shim (de-cruft)
+
+The __getattr__ in src/models.py lazy-loads moved classes on first access. To remove it, update the ~30 consumer sites to import directly from subsystem files.
+
+**Consumer sites:** tests/test_*.py and src/app_controller.py, src/aggregate.py, etc.
+
+**Migration pattern:**
+```python
+# OLD:
+from src.models import Ticket
+# NEW:
+from src.mma import Ticket
+```
+
+### FR6: Move DEFAULT_TOOL_CATEGORIES to src/ai_client.py
+
+DEFAULT_TOOL_CATEGORIES is a categorization of MCP tools, which is the AI client's domain. Move it from src/models.py to src/ai_client.py.
+
+**Consumer site:** src/app_controller.py uses DEFAULT_TOOL_CATEGORIES.
+
+### FR7: Move Pydantic proxies to src/api_hooks.py
+
+The Pydantic proxies (_create_generate_request, _create_confirm_request, the Pydantic-specific __getattr__) are API-specific. Move them from src/models.py to src/api_hooks.py.
+
+**Consumer sites:** src/api_hooks.py, src/api_hook_client.py
+
+### FR8: Standardize ImGui usage on imgui_scopes.py context managers
+
+The files src/markdown_helper.py, src/theme_2.py, src/theme_nerv.py, src/theme_nerv_fx.py all use ImGui directly. Standardize on the imgui_scopes.py context manager pattern.
+
+**Pattern:**
+```python
+# OLD (direct):
+imgui.begin("My Window")
+# ... content ...
+imgui.end()
+
+# NEW (via imgui_scopes):
+with imgui.begin("My Window"):
+    # ... content ...
+```
+
+## Non-Functional Requirements
+
+- NFR1: 1-space indentation
+- NFR2: CRLF line endings on Windows
+- NFR3: No comments in source code
+- NFR4: Per-task atomic commits with git notes
+- NFR5: No new pip dependencies
+- NFR6: Result[T] returns for fallible fns
+
+## Architecture Reference
+
+- module_taxonomy_refactor_20260627 spec (the v2 4-criteria rule, data/view/ops split)
+- module_taxonomy_refactor_20260627 plan (the v2 16-commit plan)
+- module_taxonomy_refactor_20260627 TRACK_COMPLETION (Tier 2's report)
+- FOLLOWUP_module_taxonomy_v2_review (the review identifying these 2 critical bugs + 4 de-cruft tasks)
+- FOLLOWUP_module_taxonomy_refactor_20260627_recoverable (data is NOT lost)
+- scripts/generate_type_registry.py (the NameError bug)
+- scripts/audit_code_path_audit_coverage.py (the missing latest symlink)
+- src/models.py (the file being cleaned up)
+- src/imgui_scopes.py (the context manager module for FR8)
+
+## Out of Scope
+
+- The 4-criteria rule itself (established in v2)
+- The data/view/ops split (established in v2)
+- Merging consumer files into the taxonomy moves (that's the v2 track)
+- The RAG test pre-existing flake
+- New ImGui-using files (only standardize existing)
+- Anything in src/aggregate.py (513 lines), src/app_controller.py (4869 lines), src/gui_2.py (7773 lines)
+- The cruft_elimination_20260627 track's work (already SHIPPED)

+## Risks
+
+| # | Risk | Likelihood | Mitigation |
+|---|---|---|---|
+| R1 | Fixing the NameError: LEGACY_NAMES bug breaks other things | low | Run the type registry generation after fix; if it fails, investigate the original definition |
+| R2 | The latest symlink doesn't work on Windows (symlink restrictions) | medium | Use a .latest marker file instead of a symlink; update the audit script to read the marker |
+| R3 | Removing the __getattr__ shim breaks 30+ consumer sites | high | Per-file migration; run regression tests after each consumer-site update |
+| R4 | Moving DEFAULT_TOOL_CATEGORIES breaks app_controller.py | low | Single consumer; update + verify |
+| R5 | Moving Pydantic proxies breaks api_hooks.py and api_hook_client.py | low | 2 consumer sites; update + verify |
+| R6 | Standardizing ImGui usage in theme/markdown files breaks their tests | medium | Per-file refactor; run theme/markdown tests after each |
+| R7 | The v2 spec update is itself a "rewriting commits" pattern | low | The v2 spec is a TRACK ARTIFACT, not a commit in the v2 branch; updates to v2 spec are normal |

+# Plan: ImGui Test Engine Integration (Bridge via API Hooks)
+
+Track: `test_engine_integration_20260627`
+Branch: master (parallel-safe; touches `sloppy.py`, `src/gui_2.py`, `src/app_controller.py`, `src/api_hooks.py`, `src/api_hook_client.py`, `tests/conftest.py`, new `tests/test_test_engine_smoke.py` — zero overlap with the running tier2 taxonomy branch or the enforcement_gap_closure track)
+Spec: `conductor/tracks/test_engine_integration_20260627/spec.md`
+
+All Python edits use 1-space indentation. No comments in body. CRLF preserved.
+
+---
+
+## Phase 1: Enable the Test Engine in the App
+
+Focus: Add `--enable-test-engine` CLI flag, set `runner_params.use_imgui_test_engine`, add the `register_tests` callback with a placeholder smoke test.
+
+- [ ] Task 1.1: Write failing test for `--enable-test-engine` flag + engine activation
+  - **WHERE:** `tests/test_test_engine_smoke.py` (NEW file)
+  - **WHAT:** Test 1: `test_engine_enabled` — start `live_gui` (which will pass `--enable-test-engine`), verify the engine is active by calling `client.get_test_status()` (new method, implemented in Phase 3) and asserting `queue_empty == True` (engine is running, no tests queued). This test will FAIL before Phase 1 + Phase 3 land (the endpoint doesn't exist yet).
+  - **HOW:** Use the `live_gui` fixture. Call `client.get_test_status()`. Assert the response has a `queue_empty` field. (The method is added in Phase 3; the test is written first per TDD.)
+  - **SAFETY:** No `live_gui` state mutation; just a GET request.
+  - **COMMIT:** `test(smoke): add failing test for test engine activation`
+  - **GIT NOTE:** Red-phase test for the `--enable-test-engine` flag + engine activation.
+
+- [ ] Task 1.2: Add `--enable-test-engine` CLI flag to `sloppy.py` + `AppController`
+  - **WHERE:** `sloppy.py:35` (add arg), `src/app_controller.py:1042` (add `test_engine_enabled` field)
+  - **WHAT:**
+    1. `sloppy.py`: add `parser.add_argument("--enable-test-engine", action="store_true", help="Enable Dear ImGui Test Engine for automated UI testing")` after the `--enable-test-hooks` line.
+    2. `src/app_controller.py:1042`: add `self.test_engine_enabled: bool = ("--enable-test-engine" in sys.argv)` after the `test_hooks_enabled` line.
+  - **HOW:** Use `manual-slop_edit_file` MCP tool. 1-space indent.
+  - **SAFETY:** The flag is opt-in; normal runs are unaffected.
+  - **COMMIT:** `feat(cli): add --enable-test-engine flag`
+  - **GIT NOTE:** CLI flag for test engine; mirrors the --enable-test-hooks pattern at app_controller.py:1042.
+
+- [ ] Task 1.3: Enable the engine in `App.run()` + add `_register_imgui_tests` callback
+  - **WHERE:** `src/gui_2.py:641` (after `RunnerParams()` construction) + `src/gui_2.py:~700` (new `_register_imgui_tests` method)
+  - **WHAT:**
+    1. In `App.run()` between line 641 (`self.runner_params = _hi.RunnerParams()`) and line 684 (`callbacks.show_gui = ...`), add:
+       ```python
+       if getattr(self.controller, "test_engine_enabled", False):
+        self.runner_params.use_imgui_test_engine = True
+        self.runner_params.callbacks.register_tests = self._register_imgui_tests
+       ```
+    2. Add `_register_imgui_tests(self)` method on `App` (after `_post_init`, ~line 700):
+       ```python
+       def _register_imgui_tests(self) -> None:
+        from imgui_bundle import hello_imgui
+        from imgui_bundle.imgui import test_engine
+        engine = hello_imgui.get_imgui_test_engine()
+        test = test_engine.register_test(engine, "Smoke Tests", "Tab Switch")
+        def smoke_func(ctx) -> None:
+         from imgui_bundle.imgui.test_engine_checks import CHECK
+         ctx.set_ref("###manual slop")
+         ctx.item_click("**/Session")
+         CHECK(True)
+        test.test_func = smoke_func
+       ```
+       The exact `set_ref` + `item_click` targets are determined during implementation by inspecting the running GUI's label tree. The smoke test should click a harmless tab (e.g., switch to "Session" tab) and `CHECK(True)` as a placeholder assertion. The real assertion (verify the tab actually switched) is added once the label path is confirmed.
+  - **HOW:** Use `manual-slop_edit_file` / `manual-slop_py_update_definition` MCP tool. 1-space indent.
+  - **SAFETY:** Guarded by `test_engine_enabled`; normal runs skip this entirely. The `register_tests` callback is only called by `hello_imgui` when `use_imgui_test_engine = True`.
+  - **COMMIT:** `feat(gui): enable test engine + register smoke test via callbacks.register_tests`
+  - **GIT NOTE:** Activates the test engine when --enable-test-engine is set; registers a placeholder smoke test.
+
+- [ ] Task 1.4: Verify the engine activates (manual)
+  - **WHAT:** Run `uv run python sloppy.py --enable-test-hooks --enable-test-engine` locally. Verify the app starts without crashing (the GIL-transfer mechanism works). Verify `hello_imgui.get_imgui_test_engine()` returns a non-None engine. This is a manual checkpoint before proceeding to Phase 2.
+  - **COMMIT:** (no commit; manual verification checkpoint)
+  - **GIT NOTE:** Manual verification that the engine + GIL transfer works with the app's existing thread layout.
+
+---
+
+## Phase 2: Build the API Hooks Bridge
+
+Focus: Add the 4 `/api/test_engine/*` endpoints to `HookServer` + the 4 methods to `ApiHookClient`.
+
+- [ ] Task 2.1: Write failing tests for the 4 new `ApiHookClient` methods
+  - **WHERE:** `tests/test_test_engine_smoke.py` (append to the file from Task 1.1)
+  - **WHAT:** 2 more tests:
+    - `test_queue_and_run_smoke_test`: queue the smoke test via `client.queue_test("Smoke Tests", "Tab Switch")`, poll via `client.wait_for_test_results(timeout=30)`, assert `results["count_success"] >= 1` and `results["count_tested"] >= 1`.
+    - `test_engine_results_shape`: call `client.get_test_results()`, assert the response dict has keys `count_tested`, `count_success`, `count_in_queue`.
+  - **HOW:** Use `live_gui` fixture. These tests fail until Phase 2 + Phase 3 land (the client methods + endpoints don't exist yet).
+  - **SAFETY:** The smoke test queues a harmless tab-switch; no destructive state change.
+  - **COMMIT:** `test(smoke): add failing tests for queue_test + wait_for_test_results + get_test_results`
+  - **GIT NOTE:** Red-phase tests for the 4 new ApiHookClient methods.
+
+- [ ] Task 2.2: Add the 4 `/api/test_engine/*` endpoints to `HookServer`
+  - **WHERE:** `src/api_hooks.py` — `do_GET` (line 157) + `do_POST` (line 490)
+  - **WHAT:** Add 4 new `elif` branches:
+    1. `do_GET`: `elif self.path == "/api/test_engine/status":` — lazy-import `hello_imgui` + `test_engine`; get engine via `hello_imgui.get_imgui_test_engine()`; call `test_engine.is_test_queue_empty(engine)`; respond `{"queue_empty": bool}`.
+    2. `do_GET`: `elif self.path == "/api/test_engine/results":` — get engine; create `TestEngineResultSummary()`; call `test_engine.get_result_summary(engine, out_results)`; respond `{"count_tested": N, "count_success": N, "count_in_queue": N}`.
+    3. `do_POST`: `elif self.path == "/api/test_engine/queue":` — body `{"group": "...", "name": "..."}`; get engine; find test via `test_engine.find_test_by_name(engine, group, name)`; if found, `test_engine.queue_test(engine, test)`; respond `{"status": "queued"}` or `{"error": "test not found"}` (404).
+    4. `do_POST`: `elif self.path == "/api/test_engine/abort":` — get engine; `test_engine.abort_current_test(engine)`; respond `{"status": "aborted"}`.
+  - **HOW:** Follow the existing endpoint pattern (lines 499-505 for POST, lines 231-241 for GET). Use `_get_app_attr(app, "controller")` to check `test_engine_enabled`; if not enabled, respond 503. Use `json.dumps(...)` for the response body. 1-space indent.
+  - **SAFETY:** The endpoints run on the HTTP handler thread. `hello_imgui.get_imgui_test_engine()` is a C++ accessor (thread-safe). `queue_test` / `is_test_queue_empty` / `get_result_summary` are thread-safe C++ engine operations (the engine is designed for cross-thread test scheduling). `abort_current_test` is also thread-safe.
+  - **COMMIT:** `feat(api_hooks): add /api/test_engine/* bridge endpoints`
+  - **GIT NOTE:** 4 new endpoints: queue, status, results, abort; bridge the test process to the engine via HTTP.
+
+- [ ] Task 2.3: Add the 4 new methods to `ApiHookClient`
+  - **WHERE:** `src/api_hook_client.py` (after the existing methods, ~line 500)
+  - **WHAT:** 4 new methods:
+    1. `queue_test(self, group: str, name: str) -> dict` — POST `/api/test_engine/queue` with `{"group": group, "name": name}`; return the response dict.
+    2. `get_test_status(self) -> dict` — GET `/api/test_engine/status`; return `{"queue_empty": bool}`.
+    3. `get_test_results(self) -> dict` — GET `/api/test_engine/results`; return `{"count_tested": N, "count_success": N, "count_in_queue": N}`.
+    4. `wait_for_test_results(self, timeout: float = 30.0) -> dict` — poll `get_test_status()` every 0.5s until `queue_empty == True` or timeout; then return `get_test_results()`. On timeout, return the last results (with a `timed_out: True` field).
+  - **HOW:** Follow the existing method pattern (e.g., `get_status` at line 105, `push_event` at line 156). Use `requests.get/post` + retry. 1-space indent.
+  - **SAFETY:** Pure HTTP client; no thread safety concerns.
+  - **COMMIT:** `feat(api_hook_client): add queue_test + get_test_status + get_test_results + wait_for_test_results`
+  - **GIT NOTE:** 4 new client methods mirroring the 4 new endpoints; wait_for_test_results replaces time.sleep+get_value polling.
+
+- [ ] Task 2.4: Run Phase 2 tests (Green phase)
+  - **WHAT:** `uv run pytest tests/test_test_engine_smoke.py -v --timeout=60`. All 3 tests must pass. If the smoke test (test_queue_and_run_smoke_test) fails, the most likely cause is the `set_ref` / `item_click` label path being wrong — debug by using `imgui.show_id_stack_tool_window()` or `ctx.window_info("manual slop")` to find the correct label. If the GIL transfer fails, the app will crash — that's a hard blocker; report to user.
+  - **COMMIT:** `conductor(state): Phase 2 green-phase verification` (or skip if no code changes)
+  - **GIT NOTE:** Green-phase verification for the 4 new endpoints + 4 new client methods.
+
+---
+
+## Phase 3: Live_gui Fixture + Full Smoke Test
+
+Focus: Pass `--enable-test-engine` in the `live_gui` fixture + verify the full bridge works end-to-end.
+
+- [ ] Task 3.1: Update `live_gui` fixture to pass `--enable-test-engine`
+  - **WHERE:** `tests/conftest.py:792`
+  - **WHAT:** Change `gui_args = ["uv", "run", "python", "-u", gui_script, "--enable-test-hooks"]` to include `"--enable-test-engine"`:
+    ```python
+    gui_args = ["uv", "run", "python", "-u", gui_script, "--enable-test-hooks", "--enable-test-engine"]
+    ```
+  - **HOW:** `manual-slop_edit_file` MCP tool. 1-space indent.
+  - **SAFETY:** The engine is idle when no tests are queued. Existing `live_gui` tests that don't use the test engine are unaffected (the engine adds sub-ms per-frame overhead).
+  - **COMMIT:** `test(conftest): pass --enable-test-engine in live_gui fixture`
+  - **GIT NOTE:** Engine activates on every live_gui run; idle when no tests queued.
+
+- [ ] Task 3.2: Run the full smoke test suite (Green phase)
+  - **WHAT:** `uv run pytest tests/test_test_engine_smoke.py -v --timeout=60`. All 3 tests pass. Then run a small batch of existing `live_gui` tests to verify no regression: `uv run pytest tests/test_workspace_profiles_restoration.py tests/test_undo_redo_lifecycle.py -v --timeout=120`.
+  - **COMMIT:** `conductor(state): Phase 3 green-phase verification`
+  - **GIT NOTE:** Full bridge verified: pytest → HTTP → HookServer → engine → scenario thread → ctx.item_click → GUI thread → CHECK → results → HTTP → pytest assert.
+
+---
+
+## Phase 4: End-of-Track Report + State Update
+
+- [ ] Task 4.1: Write end-of-track report
+  - **WHERE:** `docs/reports/TRACK_COMPLETION_test_engine_integration_20260627.md` (NEW file)
+  - **WHAT:** Report following the precedent:
+    - TL;DR
+    - Phase summary (each phase + commits + status)
+    - Verification Criteria status (mapped to spec G1-G7)
+    - Threading model verification (did the GIL transfer work? any crashes? any state-access issues from the scenario thread?)
+    - The 4 new endpoints + 4 new client methods documented
+    - The smoke test result
+    - Handoff to Track 2 (docking test migration) — what's now possible that wasn't before
+    - Known limitations (engine requires a live window; not headless; the interactive panel is not shown)
+  - **COMMIT:** `docs(reports): TRACK_COMPLETION_test_engine_integration_20260627`
+  - **GIT NOTE:** End-of-track report; documents the bridge + threading model verification + Track 2 handoff.
+
+- [ ] Task 4.2: Update `conductor/tracks.md` + `conductor/chronology.md` + `state.toml`
+  - **WHAT:**
+    1. `state.toml`: mark all phases "completed" with checkpoint SHA; `status = "completed"`.
+    2. `conductor/tracks.md`: add row for this track (status "shipped").
+    3. `conductor/chronology.md`: prepend row for `2026-06-27 | test_engine_integration_20260627 | shipped | ...`.
+  - **COMMIT:** `conductor(state): test_engine_integration_20260627 SHIPPED + TRACK_COMPLETION`
+  - **GIT NOTE:** Track state + chronology + tracks.md closed out.
+
+- [ ] Task 4.3: Conductor - User Manual Verification
+  - **WHAT:** Present the results: the smoke test pass, the threading model verification, the 4 new endpoints, the 4 new client methods. PAUSE for user sign-off.
+  - **COMMIT:** (no commit; user-confirmation gate)
+  - **GIT NOTE:** User sign-off record.

+# Track Specification: ImGui Test Engine Integration (Bridge via API Hooks)
+
+## Overview
+
+Integrate the Dear ImGui Test Engine (`imgui_bundle.imgui.test_engine`) into Manual Slop's test infrastructure to enable high-fidelity simulation of user interactions — docking, window focus, panel visibility, drag-and-drop, keyboard input — that the current Hook API cannot express.
+
+**The design principle:** the API hooks layer (`HookServer` on :8999 + `ApiHookClient`) remains the **single communication boundary** between the test process (pytest) and the GUI subprocess. The test engine is integrated *behind* the API hooks, not alongside them. New `/api/test_engine/*` endpoints bridge the test process to the engine's `queue_test` / `get_result_summary` API. The engine's `test_func` closures run on the engine's scenario thread (GIL-transferred by `hello_imgui`/`immapp`); they use `ctx.item_click("**/Label")`, `ctx.dock_into(src, dst, dir)`, `ctx.window_focus(ref)` etc. to post simulated input events to the GUI render thread. The existing `_pending_gui_tasks` queue and the engine's input simulation are two separate event injection paths into the same GUI thread; they compose without conflict.
+
+This is **Track 1 of 3** in the test engine campaign. Track 1 = enable the engine + build the bridge + smoke test. Track 2 (follow-up) = migrate docking/focus/panel tests. Track 3 (follow-up) = visual regression via screenshot capture.
+
+## Current State Audit (as of master `77b70226`)
+
+### Already Implemented (DO NOT re-implement)
+
+- **`imgui_bundle` v1.92.5** (pinned in `pyproject.toml:7`) ships the test engine compiled into the nanobind binary. Verified: `from imgui_bundle import imgui; imgui.test_engine.TestEngine` is a live class; `imgui.test_engine.register_test`, `imgui.test_engine.queue_test`, `imgui.test_engine.get_result_summary`, `imgui.test_engine.TestContext` with `dock_into`, `window_focus`, `item_click`, `capture_screenshot_window`, etc. are all present (verified via `dir()` enumeration — ~95 `TestContext` methods + ~35 module-level functions). The `.pyi` stub at `.venv/Lib/site-packages/imgui_bundle/imgui/test_engine.pyi` documents the full API.
+
+- **`hello_imgui.RunnerParams.use_imgui_test_engine: bool = False`** (`.venv/Lib/site-packages/imgui_bundle/hello_imgui.pyi:2969`) — the flag that enables the engine. When `True`, `hello_imgui`/`immapp` compiles the engine into the runner and provides the GIL-transfer mechanism for the scenario thread. The engine is **already compiled into the wheel** (the C++ build flag `-DHELLOIMGUI_WITH_TEST_ENGINE=ON` was set for the published wheel); the Python-side flag just activates it.
+
+- **`hello_imgui.get_imgui_test_engine()`** (`.venv/Lib/site-packages/imgui_bundle/hello_imgui.pyi:3355`) — returns the live `TestEngine` instance after `use_imgui_test_engine = True`. Verified callable.
+
+- **`RunnerCallbacks.register_tests: VoidFunction`** (`.venv/Lib/site-packages/imgui_bundle/hello_imgui.pyi:1809`) — the callback that `hello_imgui` invokes at startup to let the app register tests via `imgui.test_engine.register_test(engine, group, name)`. The demo at `.venv/Lib/site-packages/imgui_bundle/demos_python/demos_immapp/demo_testengine.py` shows the full pattern.
+
+- **`imgui_bundle.imgui.test_engine_checks.CHECK(result: bool)`** — the assertion primitive that emits pass/fail to the engine's result log with file:line traceback. Verified importable.
+
+- **The app already uses `hello_imgui.RunnerParams` + `immapp.run()`** — the exact integration path the test engine requires:
+  - `src/gui_2.py:641`: `self.runner_params = _hi.RunnerParams()`
+  - `src/gui_2.py:684-688`: `self.runner_params.callbacks.show_gui/show_menus/load_additional_fonts/setup_imgui_style/post_init` are set
+  - `src/gui_2.py:1486`: `immapp.run(app.runner_params, ...)` — the main loop entry point
+  - The GIL-transfer mechanism is built into `immapp.run` when `use_imgui_test_engine = True`; no additional threading code is needed on the Python side.
+
+- **`HookServer`** (`src/api_hooks.py:857`) — the HTTP server on `127.0.0.1:8999`, started when `--enable-test-hooks` is passed. The `do_GET` method (line 157) and `do_POST` method (line 490) use a flat `if/elif self.path == "/api/..."` dispatch. The server holds `self.app` (the `App` instance) and accesses it via `_get_app_attr(app, ...)` helpers. The `_pending_gui_tasks` queue (`app_controller.py:900`) + `_pending_gui_tasks_lock` (`app_controller.py:822`) + `_process_pending_gui_tasks()` (`app_controller.py:1844`, called per-frame from `gui_2.py:1759`) is the existing thread-safe command queue from HTTP handler thread → main render thread.
+
+- **`ApiHookClient`** (`src/api_hook_client.py`) — the Python client with retry logic, health-check polling, `wait_for_server(timeout)`, `push_event(action, payload)`, `get_value(item)`, `set_value(item, value)`, `click(item)`, `wait_for_event(event_type, timeout)`, etc. Used by all `live_gui` tests.
+
+- **`live_gui` fixture** (`tests/conftest.py:641`) — session-scoped; spawns `sloppy.py --enable-test-hooks --config=<temp>` as a subprocess; polls `http://127.0.0.1:8999/status` until ready; yields a `_LiveGuiHandle` with `.client` (an `ApiHookClient`), `.process`, `.workspace`. The fixture's subprocess args are at `conftest.py:792`: `gui_args = ["uv", "run", "python", "-u", gui_script, "--enable-test-hooks"]`.
+
+- **`sloppy.py`** (79 lines) — the entry point. CLI flags at lines 31-36: `--headless`, `--web-host`, `--web-port`, `--enable-test-hooks`, `--config`. The `else` branch at line 75 (the normal GUI mode) calls `from src.gui_2 import main; main()`.
+
+- **`AppController.test_hooks_enabled`** (`src/app_controller.py:1042`) — set via `"--enable-test-hooks" in sys.argv` or `SLOP_TEST_HOOKS=1` env var. Same pattern works for `--enable-test-engine`.
+
+### Gaps to Fill (This Track's Scope)
+
+- **GAP-1: The test engine is not enabled.** `runner_params.use_imgui_test_engine` is never set to `True`. No `callbacks.register_tests` callback exists. The engine's scenario thread + GIL-transfer mechanism are dormant.
+
+- **GAP-2: No `/api/test_engine/*` bridge endpoints.** The `HookServer` has no way for the test process to queue a test, poll results, or abort a running test. The test engine API (`queue_test`, `get_result_summary`, `is_test_queue_empty`, `abort_current_test`) is only accessible from inside the GUI process — not from the HTTP boundary.
+
+- **GAP-3: No `ApiHookClient` methods for test engine operations.** The client has `click`, `set_value`, `push_event`, `wait_for_event` — but no `queue_test`, `wait_for_test_results`, `get_test_results`.
+
+- **GAP-4: `live_gui` fixture doesn't pass `--enable-test-engine`.** The subprocess at `conftest.py:792` only passes `--enable-test-hooks`. Without the engine flag, the engine won't activate even after GAP-1 is fixed.
+
+- **GAP-5: No smoke test proving the end-to-end threading model works.** The test engine's scenario thread + GIL transfer is the highest-risk piece. A minimal smoke test (register a trivial test that clicks a known button + asserts a state change, queue it via the API, poll for results, assert pass) is needed to prove the bridge works before Track 2 migrates real tests.
+
+### Architecture: Why the API hooks + test engine compose
+
+```
+pytest test process
+  └── ApiHookClient (HTTP :8999)          ← single communication boundary (KEPT)
+       └── HookServer.do_POST             ← new /api/test_engine/* endpoints
+            └── imgui.test_engine.queue_test(engine, test)  ← schedules on engine
+                 └── TestContext.test_func(ctx)  ← runs on engine scenario thread
+                      └── ctx.item_click("**/Label")  ← posts simulated input to GUI thread
+                           └── GUI render thread processes the simulated event
+                                └── _process_pending_gui_tasks() still runs per-frame
+                                     (existing queue; unaffected; two separate injection paths)
+```
+
+The test engine's `test_func` runs on its own thread (the scenario thread). The `ctx.*` primitives post simulated input events to the ImGui input queue on the GUI render thread. This is the same destination as real user input and the same destination as `_pending_gui_tasks` — but a different injection mechanism. The two paths are independent; they don't share state, locks, or queues. The test engine doesn't touch `_pending_gui_tasks` and vice versa.
+
+The GIL-transfer caveat (documented at the top of `test_engine.pyi`) is handled by `hello_imgui`/`immapp` when `use_imgui_test_engine = True` — the C++ layer transfers the GIL between the main thread and the scenario thread. No additional Python-side threading code is needed. The `test_func` callback runs with the GIL held; it can safely call `ctx.*` primitives (which are C++ nanobind calls that release the GIL during the simulated input wait).
+
+## Goals
+
+- **G1.** `sloppy.py` accepts `--enable-test-engine` CLI flag; when set, `App.run()` sets `runner_params.use_imgui_test_engine = True` + assigns `runner_params.callbacks.register_tests` to a method that registers tests.
+
+- **G2.** `App` has a `_register_imgui_tests(self)` method (called by `hello_imgui` at startup via the `register_tests` callback) that registers at least one smoke test ("Smoke Tests", "Click Increment Button") via `imgui.test_engine.register_test(engine, group, name)`. The smoke test's `test_func(ctx)` calls `ctx.set_ref("...")` + `ctx.item_click("**/...")` + `CHECK(...)`.
+
+- **G3.** `HookServer` (in `src/api_hooks.py`) has 4 new endpoints:
+  - `POST /api/test_engine/queue` — body `{"group": "...", "name": "..."}`; finds the test by group+name via `imgui.test_engine.find_test_by_name(engine, group, name)`; calls `queue_test(engine, test)`; responds `{"status": "queued"}`.
+  - `GET /api/test_engine/status` — calls `is_test_queue_empty(engine)`; responds `{"queue_empty": true/false}`.
+  - `GET /api/test_engine/results` — calls `get_result_summary(engine, out_results)`; responds `{"count_tested": N, "count_success": N, "count_in_queue": N}`.
+  - `POST /api/test_engine/abort` — calls `abort_current_test(engine)`; responds `{"status": "aborted"}`.
+
+- **G4.** `ApiHookClient` (in `src/api_hook_client.py`) has 4 new methods:
+  - `queue_test(group: str, name: str) -> dict` — POST to `/api/test_engine/queue`.
+  - `get_test_status() -> dict` — GET `/api/test_engine/status`.
+  - `get_test_results() -> dict` — GET `/api/test_engine/results`.
+  - `wait_for_test_results(timeout: float = 30.0) -> dict` — polls `get_test_status()` until `queue_empty == True` or timeout; then returns `get_test_results()`.
+
+- **G5.** The `live_gui` fixture passes `--enable-test-engine` in addition to `--enable-test-hooks` in the subprocess args (`conftest.py:792`). The engine activates on every `live_gui` test run.
+
+- **G6.** A smoke test in `tests/test_test_engine_smoke.py` that:
+  1. Uses the `live_gui` fixture.
+  2. Queues the smoke test via `client.queue_test("Smoke Tests", "Click Increment Button")`.
+  3. Polls via `client.wait_for_test_results(timeout=30)`.
+  4. Asserts `results["count_success"] >= 1` and `results["count_tested"] >= 1`.
+  This proves the full bridge works: pytest → HTTP → HookServer → engine → scenario thread → `ctx.item_click` → GUI thread → state change → `CHECK` → result log → `get_result_summary` → HTTP → pytest assert.
+
+- **G7.** End-of-track report at `docs/reports/TRACK_COMPLETION_test_engine_integration_20260627.md` documenting: what shipped, the threading model verification, any GIL-transfer issues encountered, and the handoff to Track 2 (docking test migration).
+
+## Functional Requirements
+
+### FR1: `--enable-test-engine` CLI flag
+
+- `sloppy.py`: add `parser.add_argument("--enable-test-engine", action="store_true", help="Enable the Dear ImGui Test Engine for automated UI testing")` alongside the existing `--enable-test-hooks` flag (line 35).
+- `src/app_controller.py`: add `self.test_engine_enabled: bool = ("--enable-test-engine" in sys.argv)` near line 1042 (same pattern as `test_hooks_enabled`).
+- `src/gui_2.py` `App.run()` (line 619): between the `RunnerParams()` construction (line 641) and the `callbacks.show_gui = ...` assignments (line 684), add:
+  ```python
+  if getattr(self.controller, "test_engine_enabled", False):
+   self.runner_params.use_imgui_test_engine = True
+   self.runner_params.callbacks.register_tests = self._register_imgui_tests
+  ```
+  This is guarded by the flag so normal runs are unaffected.
+
+### FR2: `App._register_imgui_tests(self)` method
+
+- New method on `App` in `src/gui_2.py` (near the other callback registrations, ~line 700):
+  ```python
+  def _register_imgui_tests(self) -> None:
+   """Called by hello_imgui at startup to register ImGui Test Engine tests.
+   Reads the live engine via hello_imgui.get_imgui_test_engine().
+   [C: src/gui_2.py:App.run (via callbacks.register_tests)]
+   """
+   from imgui_bundle import hello_imgui
+   from imgui_bundle.imgui import test_engine
+   engine = hello_imgui.get_imgui_test_engine()
+   # Smoke test: click a known button and verify state change
+   test = test_engine.register_test(engine, "Smoke Tests", "Click Increment Button")
+   def smoke_func(ctx) -> None:
+    from imgui_bundle.imgui.test_engine_checks import CHECK
+    ctx.set_ref("...")  # TODO: set to a known window
+    ctx.item_click("**/...")  # TODO: click a known button
+    CHECK(True)  # TODO: verify state change
+   test.test_func = smoke_func
+  ```
+  The exact button + state to click + verify is determined during implementation by inspecting the running GUI's item tree (use `ctx.window_info` / `imgui.show_id_stack_tool_window` to find labels). The smoke test should click something harmless (e.g., a tab switch, a checkbox toggle) and verify the state changed.
+
+### FR3: `/api/test_engine/*` endpoints in `HookServer`
+
+- In `src/api_hooks.py` `do_POST` (line 490): add 2 new `elif` branches for `POST /api/test_engine/queue` and `POST /api/test_engine/abort`.
+- In `src/api_hooks.py` `do_GET` (line 157): add 2 new `elif` branches for `GET /api/test_engine/status` and `GET /api/test_engine/results`.
+- All 4 endpoints guard on `test_engine_enabled` — if the engine is not active, respond `{"error": "test engine not enabled", "enabled": false}` with HTTP 503.
+- The engine instance is obtained via `hello_imgui.get_imgui_test_engine()` inside the handler (lazy import; the handler runs on the HTTP thread, but `get_imgui_test_engine()` is a C++ accessor that returns a pointer — safe to call from any thread).
+
+### FR4: `ApiHookClient` methods
+
+- In `src/api_hook_client.py`: add 4 methods per G4. Follow the existing method pattern (e.g., `get_status`, `push_event`): construct the URL, `requests.post/get`, retry on connection error, parse JSON, return the dict.
+
+### FR5: `live_gui` fixture update
+
+- In `tests/conftest.py:792`: change `gui_args` to include `"--enable-test-engine"` when the fixture spawns the subprocess. The flag flows through to `AppController.test_engine_enabled` → `App.run()` → `runner_params.use_imgui_test_engine = True`.
+
+### FR6: Smoke test
+
+- `tests/test_test_engine_smoke.py` (NEW) — 2-3 tests:
+  - `test_engine_enabled`: `client.get_value("test_engine_enabled")` returns True (or verify via a new gettable field).
+  - `test_queue_and_run_smoke_test`: queue the smoke test, poll for results, assert success.
+  - `test_engine_results_shape`: `get_test_results()` returns the expected dict shape.
+
+## Non-Functional Requirements
+
+- **1-space indentation** for all Python code.
+- **No comments in body** per AGENTS.md.
+- **CRLF line endings** preserved.
+- **Atomic per-task commits.**
+- **Thread safety:** the `test_func` runs on the engine scenario thread. It must NOT directly mutate `App` or `AppController` state — it must use `ctx.*` primitives (which post simulated input to the GUI thread). Reading state via `hello_imgui.get_imgui_test_engine()` or engine queries (`ctx.item_info`, `ctx.window_info`) is safe. The `CHECK()` assertion runs on the scenario thread but only writes to the engine's result log (thread-safe C++ structure).
+- **No `live_gui` regression:** the `--enable-test-engine` flag must not affect normal GUI behavior when `live_gui` tests are NOT using the engine. The engine's scenario thread is idle when no tests are queued. The `show_test_engine_windows` panel is NOT shown by default (only via explicit call).
+- **Performance:** the engine adds a per-frame overhead when active. The `fps_idling` settings in `runner_params` remain unchanged. The engine's overhead is sub-millisecond per frame when no tests are running.
+
+## Architecture Reference
+
+- **`docs/guide_testing.md`** — the `live_gui` fixture, the structural testing contract, the Puppeteer pattern.
+- **`docs/guide_api_hooks.md`** — the Hook API surface, the `/api/ask` protocol, the `ApiHookClient` method reference.
+- **`docs/guide_gui_2.md`** — the `App` class lifecycle, the `runner_params` construction, the `callbacks` system.
+- **`.venv/Lib/site-packages/imgui_bundle/demos_python/demos_immapp/demo_testengine.py`** — the canonical demo for the test engine integration pattern (register_tests callback + test_func closures + CHECK).
+- **`.venv/Lib/site-packages/imgui_bundle/imgui/test_engine.pyi`** — the full API stub (2644 lines). Key sections: `TestContext` methods (lines 1445-2096), module-level functions (lines 433-500, 2639+), `TestEngineResultSummary` (3 fields: count_tested, count_success, count_in_queue).
+- **`.venv/Lib/site-packages/imgui_bundle/imgui/test_engine_checks.py`** — the `CHECK(result: bool)` assertion primitive.
+- **`conductor/workflow.md`** "Live_gui Test Fragility" + "Async Setters Need Poll-For-State" — the existing patterns for `live_gui` tests; the test engine's `wait_for_test_results` replaces `time.sleep` + `get_value` polling with a single engine-side poll.
+
+## Out of Scope
+
+- **Migrating existing `live_gui` tests to the test engine.** That's Track 2 (`test_engine_docking_tests_<date>`). This track only builds the bridge + proves it works with 1 smoke test.
+- **Visual regression via screenshot capture.** That's Track 3 (`test_engine_capture_regression_<date>`). The `ctx.capture_screenshot_window` API is available but not wired in this track.
+- **Headless test execution (no GUI window).** The test engine requires a live GLFW window (the scenario thread drives the actual ImGui render loop). Headless mode is a future research item, not this track.
+- **The test engine's interactive UI panel (`show_test_engine_windows`).** Not shown by default. Can be added as a debug toggle in a follow-up.
+- **Test engine license audit.** Per the stub: "free for individuals, educational, open-source, and small businesses. Paid for larger businesses." This project is personal-use; no audit needed. Flagged for awareness only.
+- **CI wiring of the test engine.** The `live_gui` fixture already runs in CI via the batched runner. The `--enable-test-engine` flag is additive. No CI config changes needed.
+- **Touching `src/models.py` or any taxonomy files.** Zero overlap with the running `tier2/post_module_taxonomy_de_cruft_20260627` branch or the `enforcement_gap_closure_20260627` track.

+A full audit of the test suite was conducted on 2026-06-27 (`docs/reports/test_suite_audit_20260627.md`). The findings directly inform the test engine campaign's scope and sequencing:
+
+### Cruft findings (the upgrade surface)
+
+- **393 test files** total, run by `run_tests_batched.py` with a 2-level sort (fixture class → batch group). No assertion-criticality ordering exists.
+- **6 skip markers** — 4 of which are the same root cause (Gemini 503 in `summarize.summarise_file`). One track mocking the Gemini API eliminates all 4.
+- **60 files use `time.sleep`** (38 of them live_gui) — the anti-pattern explicitly banned in `workflow.md`. Each is a latent race condition. The test engine's `wait_for_test_results(timeout)` replaces these.
+- **~12-14 one-shot phase tests** are cruft (verifying completed phases like `test_phase_3_final_verify.py`, `test_code_path_audit_phase78.py`).
+- **3 redundant clusters**: history (5 files), theme (6 files), markdown tables (5 files) — likely overlapping coverage.
+- **The `core` batch is 245 files (62% of the suite)** in a single xdist run — the bottleneck for targeted verification.
+
+### Test engine upgrade candidates (27 of 58 live_gui tests)
+
+These tests exercise interactions the Hook API cannot express well (docking, focus, panel visibility, pop-out, keyboard). The test engine's `ctx.dock_into`, `ctx.window_focus`, `ctx.window_resize`, `ctx.key_press`, `ctx.capture_screenshot_window` would upgrade them:
+
+- **Docking/layout**: `test_workspace_profiles_sim.py`, `test_auto_switch_sim.py`, `test_preset_windows_layout.py`, `test_gui_text_viewer.py`
+- **Pop-out panels**: `test_task_dag_popout_sim.py`, `test_usage_analytics_popout_sim.py`
+- **Command palette + keyboard**: `test_command_palette_sim.py`, `test_undo_redo_sim.py`
+- **MMA UI flows**: `test_mma_step_mode_sim.py`, `test_mma_concurrent_tracks_sim.py`, `test_visual_mma.py`, `test_visual_sim_mma_v2.py`
+- **Visual regression candidates**: `test_visual_orchestration.py`, `test_visual_sim_gui_ux.py`, `test_live_markdown_render.py`, `test_gui_stress_performance.py`
+- **Hook API integration**: `test_hooks.py`, `test_reset_session_clears_mma_and_rag.py`, `test_live_workflow.py`, `test_extended_sims.py`
+- **Other UI interactions**: `test_gui_context_presets.py`, `test_tool_management_layout.py`, `test_selectable_ui.py`, `test_saved_presets_sim.py`, `test_system_prompt_sim.py`, `test_z_negative_flows.py`
+
+**~44 live_gui tests are fine as-is** (provider tests, API endpoint tests, model/logic tests) — the test engine adds no value for pure-logic tests.
+
+### New test capabilities enabled ONLY by the test engine
+
+- Drag-and-drop docking (`ctx.dock_into`)
+- Window focus order (`ctx.window_focus`)
+- Window resize (`ctx.window_resize`)
+- Keyboard shortcuts (`ctx.key_press` — Ctrl+Z, Ctrl+Shift+P, etc.)
+- Tab close (`ctx.tab_close`)
+- Screenshot visual regression (`ctx.capture_screenshot_window` + baseline diff)
+- Tree open/close (`ctx.item_open_all`)
+- Multi-step input (`ctx.key_chars` + `ctx.key_press(Enter)`)
+- Item hover + tooltip (`ctx.item_hold`)
+- Table column resize (`ctx.table_resize_column`)
+
+### Proposed ordering taxonomy (assertion-criticality-based)
+
+The audit proposes a 3-dimension sort: **(criticality, fixture_class, subsystem)** with 6 criticality levels:
+
+| Level | Name | Description | Approx count |
+|---|---|---|---|
+| C0 | Smoke | "Does the app start and respond?" | ~3 |
+| C1 | Structural | "Do core subsystems exist and have the right shape?" | ~45 |
+| C2 | Behavioral | "Do subsystems work in isolation?" | ~200 |
+| C3 | Integration | "Do subsystems compose correctly?" | ~50 |
+| C4 | UI/Visual | "Does the GUI render + respond to user input?" | 27 (test engine candidates) |
+| C5 | Stress/Perf | "Does it hold under load?" | ~8 |
+
+The key insight: the current `live_gui` tier (58 tests) is a monolithic batch mixing C0/C3/C4/C5. Splitting by criticality enables fast-fail (C0 runs first; if it fails, skip the rest) + targeted verification (run only C4-ui when testing a GUI change).
+
+### Recommended campaign sequence (informed by the audit)
+
+1. **`test_engine_integration_20260627`** (this track) — build the bridge
+2. **`test_suite_cruft_cleanup_<date>`** (new, not yet initialized) — delete one-shot cruft, fix Gemini 503 skips, consolidate redundant clusters, replace `time.sleep` with poll loops
+3. **`test_ordering_taxonomy_<date>`** (new, not yet initialized) — add the criticality dimension to the batched runner (`categorizer.py` + `batcher.py` + `test_categories.toml`)
+4. **`test_engine_migration_<date>`** (Campaign A Track 2) — migrate the 27 high-value live_gui tests to the test engine, re-classifying them as C4-ui in the new ordering

+# Plan: Video Analysis Campaign 2 (4 AI Videos, 3-Pass)
+
+Track: `video_analysis_campaign_2_20260627`
+Branch: master (research track; no code changes, no test changes — pure analysis + reports)
+Spec: `conductor/tracks/video_analysis_campaign_2_20260627/spec.md`
+
+This is an umbrella track. The plan covers Phase 0 (umbrella setup) + Phase 1 (Pass 1 information extraction for 4 videos). Pass 2 + Pass 3 plans are authored as sub-tracks once Pass 1 ships.
+
+---
+
+## Phase 0: Umbrella Setup
+
+Focus: Verify the pipeline works for the 4 new videos; scaffold the child track directories.
+
+- [ ] **Step 0.1: Verify the video acquisition pipeline works for all 4 videos**
+
+**WHAT:** Run `scripts/video_analysis/download_video.py` for each of the 4 URLs. Verify the videos download successfully via `yt-dlp`. Some videos may fail oEmbed (as the prior campaign experienced with 2 E-cluster videos); `yt-dlp` may still work.
+
+**HOW:**
+```bash
+uv run python -m scripts.video_analysis.download_video "https://youtu.be/l6DKRf-fAAM" --slug entropy_compression
+uv run python -m scripts.video_analysis.download_video "https://www.youtube.com/watch?v=72Xj8k5WQX4" --slug lecun_world_models
+uv run python -m scripts.video_analysis.download_video "https://youtu.be/kYkIdXwW2AE" --slug lecun_bet_against_llms
+uv run python -m scripts.video_analysis.download_video "https://youtu.be/t7_ZXgfJVG8" --slug recursive_self_improvement
+```
+
+**VERIFY:** 4 video files downloaded. If any fail, document the failure + alternative acquisition method.
+
+- [ ] **Step 0.2: Scaffold the 4 child track directories**
+
+**WHERE:** `conductor/tracks/video_analysis_2_<slug>_20260627/` (4 directories)
+
+**WHAT:** Create the directories with placeholder spec.md + state.toml files. Each child track is a Pass 1 report producer.
+
+- [ ] **Step 0.3: Commit the umbrella setup**
+
+```bash
+git add conductor/tracks/video_analysis_campaign_2_20260627/ conductor/tracks/video_analysis_2_*/
+git commit -m "conductor(track): scaffold video_analysis_campaign_2_20260627 (umbrella + 4 children)"
+```
+
+---
+
+## Phase 1: Pass 1 — Information Extraction (4 Videos)
+
+Focus: Produce 4 deep-dive reports using the existing pipeline. Each video is a child track executed independently.
+
+- [ ] **Step 1.1: Video 1 — entropy_compression (Reinventing Entropy | Compression is Intelligence Part 1)**
+
+**URL:** https://youtu.be/l6DKRf-fAAM

+6. Write `report.md` (1,000-10,000 LOC) — lossless preservation of the video's content.
+
+**Expected content:** Shannon entropy, Kolmogorov complexity, compression as intelligence, the relationship between compression and prediction. This video is the most directly relevant to Campaign A (directive encoding = compression of instructions).

+- [ ] **Step 2.1: Write the synthesis report**
+
+**WHERE:** `conductor/tracks/video_analysis_2_synthesis_20260627/report.md`

+- Connection to the prior campaign: which of the 12 prior videos share themes with these 4 new ones (especially `entropy_epiplexity` for video 1, `cs229_building_llms` for videos 2-3).
+- Cross-campaign insights: what the video analysis suggests for Campaign A (directive encoding). Specifically: does the entropy/compression video suggest a principled way to measure directive encoding efficiency? Do LeCun's world-model ideas suggest directive encoding should account for non-autoregressive architectures?

+# Track Specification: Video Analysis Campaign 2 (4 AI Videos, 3-Pass)
+
+## Overview
+
+A research campaign analyzing 4 new AI-related YouTube videos using the established 3-pass architecture from the previous 12-video campaign (Pass 1: extract → Pass 2: deobfuscate → Pass 3: project to C11/Python). The campaign reuses the existing lexicon v2 + C11 reference from the prior campaign.
+
+The 4 videos share a theme — compression, entropy, world models, and recursive self-improvement — that is directly relevant to the directive-encoding research in Campaign A (the directive hot-swap harness). The two campaigns are siblings: intellectual cross-pollination, no hard dependency, can run in parallel.
+
+**This spec covers the umbrella track.** The per-video child tracks (Pass 1 reports) and the deobfuscation sub-tracks (Pass 2 + Pass 3) are initialized as children once the umbrella is approved.
+
+## The 4 Videos
+
+| # | Title | URL | Cluster | Topic |
+|---|---|---|---|---|
+| 1 | Reinventing Entropy \| Compression is Intelligence Part 1 | https://youtu.be/l6DKRf-fAAM | A (compression/entropy) | Shannon entropy, compression as intelligence, Kolmogorov complexity |
+| 2 | Yann LeCun: World Models: Enabling the next AI revolution | https://www.youtube.com/watch?v=72Xj8k5WQX4 | B (world models) | LeCun's world model architecture; JEPA; planning via latent dynamics |
+| 3 | Yann LeCun's $1B Bet Against LLMs [Part 1] | https://youtu.be/kYkIdXwW2AE | B (world models) | LeCun's critique of LLMs; autoregressive limitations; path toward reasoning |
+| 4 | Recursive Self-Improvement | https://youtu.be/t7_ZXgfJVG8 | C (meta-AI) | Recursive self-improvement; alignment; bootstrapping intelligence |
+
+**Cluster assignment:**
+- **A (compression/entropy):** video 1 — directly relevant to the directive-encoding question (how do you compress information for an LLM?)
+- **B (world models):** videos 2-3 — LeCun's world-model work informs how LLMs model directive intent and whether alternative architectures change the encoding question
+- **C (meta-AI):** video 4 — recursive self-improvement is the meta-question of whether better directive encodings can be discovered iteratively
+
+## Current State Audit (as of master `03c7cfd5`)
+
+### Already Implemented (from the prior campaign — DO NOT re-implement)
+
+- **`scripts/video_analysis/` pipeline** (7 modules): `download_video.py`, `extract_transcript.py`, `extract_keyframes.py`, `ocr_frames.py`, `synthesize_report.py`, `error_types.py`, `__init__.py`. These are the reusable tooling from the prior campaign. Pass 1 reuses them directly.
+
+- **Lexicon v2** (from `video_analysis_deob_lexicon_v2_20260623`): the codified deobfuscation spec with 76 terms, the 5 load-bearing rules (Boundedness, Form-anchor, Etymology, Lossless, Encoding-explicit), the constructive type-theoretic foundation, and the per-language `<<` / `>>` rendering. Pass 2 starts from v2; may produce v3 corrections if the new videos surface notation the lexicon doesn't cover.
+
+- **C11 reference** (from `video_analysis_deob_c11_reference_20260623`): the user's idiomatic C11 style (byte-width types, underscore-suffixed modifiers, hand-rolled DSL, memory ordering vocabulary, slice + arena, design-doc headers). Pass 3 uses this as the projection target.
+
+- **Pass 3 projection pattern** (from `video_analysis_deob_c11_reference_20260623` + `pass_3_c11_python_projection_20260623`): per-video deliverables = C11 (.c + .h) or Python (.py) + 3-4 markdown docs (translation, decoder, notes). 4 + 3 verification criteria per the v2 lexicon.
+
+- **The 3-pass architecture** (documented in `docs/reports/2026-06-15/CAMPAIGN_CLOSE_OUT_video_analysis_20260621.md`): Pass 1 captures raw content losslessly; Pass 2 applies the lexicon; Pass 3 projects to code. The v2 patch + C11 reference are sub-tracks between Pass 2 and Pass 3.
+
+### Gaps to Fill (This Campaign's Scope)
+
+- **GAP-1: No Pass 1 reports for the 4 new videos.** The prior campaign analyzed 12 videos; these 4 are new. Pass 1 produces 4 deep-dive reports (one per video) using the existing pipeline.
+
+- **GAP-2: No Pass 2 deobfuscation for the 4 new videos.** The lexicon v2 must be applied to each video's content. May produce lexicon v3 corrections if the new videos surface notation the lexicon doesn't cover (e.g., LeCun's JEPA terminology, recursive self-improvement's bootstrapping notation).
+
+- **GAP-3: No Pass 3 C11/Python projection for the 4 new videos.** Each video's deobfuscated content must be projected to C11 or Python code in the user's idiomatic style.
+
+- **GAP-4: No cross-video synthesis.** The prior campaign had a synthesis track (`video_analysis_synthesis_20260621`) that cross-referenced the 12 reports. This campaign should produce a synthesis cross-referencing the 4 new reports + connecting to the prior campaign's themes.
+
+### Relationship to Campaign A (Directive Hot-Swap Harness)
+
+The two campaigns share a theme ("how do you encode information densely for an LLM?") but are tracked and executed independently:
+
+- **Video 1 (entropy/compression)** provides theoretical grounding for information density. The directive-encoding question IS a compression question: what is the minimal token-cost encoding of a directive that maintains LLM compliance?
+- **Videos 2-3 (LeCun world models)** inform how LLMs model directive intent. If LLMs are autoregressive pattern-matchers (LeCun's critique), then directive encoding is about pattern-matching, not reasoning. If world models are the path forward, directive encoding may need to account for non-autoregressive architectures.
+- **Video 4 (recursive self-improvement)** is the meta-question: can better directive encodings be discovered iteratively? The directive hot-swap harness IS a recursive self-improvement tool for directive encoding.
+
+Insights from the video analysis may surface alternative encoding strategies to test in Campaign A's harness. The harness's design (preset as bill-of-materials, variant as alternative encoding) mirrors the video campaign's deobfuscation pass (same content, different encoding).
+
+## Goals
+
+- **G1.** 4 Pass 1 deep-dive reports (one per video, 1,000-10,000 LOC each) produced via the existing `scripts/video_analysis/` pipeline.
+- **G2.** Pass 2 deobfuscation applied to all 4 videos using lexicon v2. Lexicon v3 corrections produced if the new videos surface notation the lexicon doesn't cover.
+- **G3.** Pass 3 C11/Python projection for all 4 videos (per-video deliverables: C11 .c + .h or Python .py + 3-4 markdown docs).
+- **G4.** A cross-video synthesis report connecting the 4 new reports to each other and to the prior campaign's themes.
+- **G5.** End-of-campaign closeout report documenting what was done, key insights, and any cross-campaign insights relevant to Campaign A.
+
+## Functional Requirements
+
+### FR1: Pass 1 — Information Extraction
+
+- Use `scripts/video_analysis/download_video.py` to acquire each video via `yt-dlp`.
+- Use `scripts/video_analysis/extract_transcript.py` to extract the transcript.
+- Use `scripts/video_analysis/extract_keyframes.py` + `scripts/video_analysis/ocr_frames.py` to extract keyframe images + OCR text.
+- Use `scripts/video_analysis/synthesize_report.py` to synthesize the deep-dive report.
+- Each report preserves the source content losslessly (no deobfuscation yet — that's Pass 2).
+- Per-video deliverable: `report.md` (1,000-10,000 LOC) + supporting artifacts (transcript, keyframes, OCR).
+- **Video slug naming:** `entropy_compression` (video 1), `lecun_world_models` (video 2), `lecun_bet_against_llms` (video 3), `recursive_self_improvement` (video 4).
+
+### FR2: Pass 2 — Deobfuscation
+
+- Apply lexicon v2 to each video's Pass 1 report.
+- Per-video deliverables: translation (3-column: original → deobfuscated → rationale) + replacement (the deobfuscated content) + decoder (the notation mapping).
+- 4 + 4 verification criteria per the v2 lexicon (lossless, bounded, constructively typed, etymology-cited + the 4 additional from the apply phase).
+- If a video surfaces notation the lexicon doesn't cover: produce lexicon v3 corrections (L-codes) + update `terms_catalog.md`.
+- **Expected new notation:** LeCun's JEPA (Joint Embedding Predictive Architecture), the world-model latent dynamics vocabulary, recursive self-improvement's bootstrapping notation.
+
+### FR3: Pass 3 — C11/Python Projection
+
+- Project each video's deobfuscated content to C11 (.c + .h) or Python (.py) in the user's idiomatic style.
+- Use the C11 reference (`video_analysis_deob_c11_reference_20260623`) as the style guide.
+- Per-video deliverables: C11 or Python code + 3-4 markdown docs (translation, decoder, notes).
+- Per-language `<<` / `>>` rendering (much_less / much_greater / weakly_coupled with tolerance).
+- Encoding placeholder scheme (float / integer / Scalar / float64).
+- Code may or may not run (per user 2026-06-23: "code may or may not run").
+
+### FR4: Cross-Video Synthesis
+
+- A synthesis report connecting the 4 new reports to each other.
+- Theme matrix: which videos touch which themes (compression, world models, self-improvement, directive encoding).
+- Concept map: how the 4 videos' concepts relate.
+- Connection to the prior campaign: which of the 12 prior videos share themes with these 4 new ones.
+- Cross-campaign insights: any insights relevant to Campaign A (directive encoding).
+
+### FR5: End-of-Campaign Closeout
+
+- A closeout report following the precedent of `docs/reports/2026-06-15/CAMPAIGN_CLOSE_OUT_video_analysis_20260621.md`.
+- Documents: what was done, key decisions, final statistics, open questions.
+- Cross-campaign insights: what the video analysis suggests for directive encoding (Campaign A).
+
+## Non-Functional Requirements
+
+- **Lossless preservation:** Pass 1 artifacts must NOT be over-summarized (data cascades to Pass 2/3). Per the prior campaign's "load-bearing directive."
+- **Lexicon v2 as starting point:** Pass 2 starts from v2. If v3 corrections are needed, they are produced as a patch track (same pattern as `video_analysis_deob_lexicon_v2_20260623`).
+- **User-led gating:** Pass 2 may require the user to gather deobfuscation samples (same as the prior campaign's warmup). Pass 3 may require the user to articulate "own caveats" before the projection starts. These are user-action gates, not agent-action gates.
+- **Reusable tooling:** the existing `scripts/video_analysis/` pipeline is reused without modification. If the pipeline needs changes (e.g., new ocr engine, new transcript API), that's a separate tooling track.
+
+## Architecture Reference
+
+- **`docs/reports/2026-06-15/CAMPAIGN_CLOSE_OUT_video_analysis_20260621.md`** — the prior campaign's closeout (the pattern this campaign follows).
+- **`scripts/video_analysis/`** — the existing pipeline (7 modules; reused for Pass 1).
+- **The lexicon v2** (from `video_analysis_deob_lexicon_v2_20260623`) — the deobfuscation substrate for Pass 2.
+- **The C11 reference** (from `video_analysis_deob_c11_reference_20260623`) — the projection target for Pass 3.
+- **`docs/superpowers/specs/2026-06-27-directive-hotswap-harness-design.md`** → now at `conductor/tracks/directive_hotswap_harness_20260627/spec.md` — the sibling campaign (Campaign A).
+
+## Out of Scope
+
+- **Modifying the existing `scripts/video_analysis/` pipeline.** If the pipeline needs changes, that's a separate tooling track.
+- **Re-analyzing the 12 prior videos.** The prior campaign is closed.
+- **Building the directive hot-swap harness.** That's Campaign A (separate track, separate spec).
+- **Authoring alternative directive encodings (v2+).** That's a future track in Campaign A.
+- **Automated compliance testing of directive encodings.** Future track.
+
+## Track Structure (Children)
+
+This is the umbrella track. Children are initialized once the umbrella is approved:
+
+- **Pass 1 children (4):** `video_analysis_2_entropy_compression_20260627`, `video_analysis_2_lecun_world_models_20260627`, `video_analysis_2_lecun_bet_against_llms_20260627`, `video_analysis_2_recursive_self_improvement_20260627`
+- **Pass 1 synthesis (1):** `video_analysis_2_synthesis_20260627`
+- **Pass 2 sub-tracks (TBD):** umbrella + warmup (if needed) + apply. Initialized after Pass 1 ships.
+- **Pass 3 sub-tracks (TBD):** initialized after Pass 2 ships.
+- **Lexicon v3 patch (conditional):** only if the new videos surface notation the lexicon doesn't cover.
+- **End-of-campaign closeout (1):** `video_analysis_campaign_2_closeout_20260627`

 To emulate the 4-Tier MMA Architecture within the standard Conductor extension without requiring a custom fork, adhere to these strict workflow policies:
 
+### 0. The Domain Distinction (CRITICAL — added 2026-06-27)
+
+This doc describes **META-TOOLING** — the AI agent orchestration layer used by Conductor agents to coordinate their own work. It is **NOT** the Application domain (the manual-slop GUI app being built).
+
+| Domain | What it does | Tools |
+|---|---|---|
+| **META-TOOLING** (this doc) | AI agent orchestration: sub-agent delegation, model switching, doc reading, file editing of THIS repo | OpenCode Task tool (sub-agent delegation), `.opencode/agents/*` (tier prompts), `manual-slop_*` MCP tools (file I/O on this repo), the canonical docs (AGENTS.md, conductor/code_styleguides/*.md) |
+| **APPLICATION** (separate) | The manual-slop GUI app the agents are building: gui_2.py, ai_client.py, the MMA *engine* (multi_agent_conductor.py, dag_engine.py), the app's MCP tools (mcp_client.py's `read_file`, `search_files`, etc.) | Documented in `docs/guide_*.md` (especially `docs/guide_meta_boundary.md`) |
+
+**When you see "sub-agent" or "Task tool" in this doc, it means META-TOOLING sub-agent delegation** (Tier 2 dispatching Tier 3 / Tier 4 to do work on this repo). It is **distinct from** the manual-slop app's `multi_agent_conductor.py` MMA engine, which is the APPLICATION-domain feature that runs inside the running GUI app.
+
 ### 1. Active Model Switching (Simulating the 4 Tiers)
 
+**UPDATED 2026-06-27:** The legacy `mma_exec.py` / `claude_mma_exec.py` bridge scripts are DEPRECATED. All tiered **META-TOOLING** sub-agent delegation now goes through the **OpenCode Task tool** (subagent invocation via the `subagent_type` parameter). This is in the meta-tooling domain (per §0); it does not affect the application's MMA engine.
+
 - **Mandatory Skill Activation:** As the very first step of any MMA-driven process, including track initialization and implementation phases, the agent MUST activate the `mma-orchestrator` skill (`activate_skill mma-orchestrator`) and their corresponding role's specific tier skill. This is crucial for enforcing the 4-Tier token firewall.
-- **The MMA Bridge (`mma_exec.py`):** All tiered delegation is routed through `uv python scripts/mma_exec.py`. This script acts as the primary bridge, managing model selection, context injection, and logging.
+- **The Sub-Agent Bridge (OpenCode Task tool):** All meta-tooling tiered delegation is now via the OpenCode Task tool with the appropriate `subagent_type`. This is the canonical META-TOOLING mechanism; it replaces the legacy `mma_exec.py` invocation. (The application-domain MMA engine in `src/multi_agent_conductor.py` is unchanged and is documented in `docs/guide_multi_agent_conductor.md`.)
 - **Model Tiers:**
     - **Tier 1 (Strategic/Orchestration):** `gemini-3.1-pro-preview`. Focused on product alignment, setup (`/conductor:setup`), and track initialization (`/conductor:newTrack`).
     - **Tier 2 (Architectural/Tech Lead):** `gemini-3-flash-preview`. Focused on architectural design and track execution (`/conductor:implement`). **Note:** Tier 2 maintains persistent memory throughout a track's implementation.
     - **Tier 3 (Execution/Worker):** `gemini-2.5-flash-lite`. Used for surgical code implementation and test generation. Operates statelessly (Context Amnesia) but has access to file I/O tools.
     - **Tier 4 (Utility/QA):** `gemini-2.5-flash-lite`. Used for log summarization and error analysis. Operates statelessly (Context Amnesia) but has access to diagnostic tools.
-- **Tiered Delegation Protocol:**
-    - **Tier 3 Worker:** `uv run python scripts/mma_exec.py --role tier3-worker "[PROMPT]"`
-    - **Tier 4 QA Agent:** `uv run python scripts/mma_exec.py --role tier4-qa "[PROMPT]"`
-- **Observability:** All hierarchical interactions are recorded in `logs/mma_delegation.log` and detailed sub-agent logs are saved to `logs/agents/`.
+- **Tiered Delegation Protocol (OpenCode Task tool):**
+    - **Tier 3 Worker:** invoke the Task tool with `subagent_type: "tier3-worker"`, providing a surgical prompt with WHERE/WHAT/HOW/SAFETY/COMMIT structure. **DO NOT** use `python scripts/mma_exec.py --role tier3-worker` (deprecated).
+    - **Tier 4 QA Agent:** invoke the Task tool with `subagent_type: "tier4-qa"`, providing the error output + an explicit instruction "DO NOT fix — provide root cause analysis only".
+    - **Tier 1 Orchestrator:** invoke the Task tool with `subagent_type: "tier1-orchestrator"` for track planning tasks.

 ### Conventions (MUST follow)
 
 1. **Test runner:** Tier 2 always uses `uv run python scripts/run_tests_batched.py`. NEVER `uv run pytest` directly. The batched runner provides tier-based filtering, parallelization (xdist), and a summary table that direct pytest does not.
-2. **Default branch:** this repo uses `master` (not `main`). When fetching or branching, use `origin/master`. Do not assume `main` exists.
-3. **Line endings:** preserve existing line endings on edit. This repo has a mix of CRLF and LF; repo-wide LF standardization is a future track. For now, do not normalize.
-4. **Throw-away scripts:** Tier 2 writes its working scripts to `scripts/tier2/artifacts/<track-name>/`, NOT the base `scripts/tier2/` directory. The base is reserved for production code (failcount.py, run_track.py, write_report.py, the .ps1 launchers). Throw-away scripts are kept for archival but isolated.
-5. **End-of-track report:** at the end of every track, Tier 2 writes `docs/reports/TRACK_COMPLETION_<track-name>.md` (follow the precedent set by `TRACK_COMPLETION_tier2_autonomous_sandbox_20260616.md`) and updates `conductor/tracks/<track-name>/state.toml` to `status = "completed"`. The user reads this report to decide merge.
-6. **Run-time expectation:** tracks are 1-4 hours. If the model reports it is running out of context, Tier 2 notes progress to disk (the failcount state file) and continues. The user expects autonomous runs to complete without manual "press continue" intervention. The `--resume` flag picks up from the last completed task.
+2. **NEVER filter test output** (added 2026-06-27 per user directive). Do NOT pipe test output through `Select-Object`, `| Select -First N`, `| Select -Last N`, `head`, `tail`, or any truncation filter. If you need to see more output later, you'll have to re-run the entire test — which wastes time and context. Instead, ALWAYS redirect to a log file: `uv run python scripts/run_tests_batched.py > tests/artifacts/tier2_state/<track>/test_run_<phase>_<task>.log 2>&1`. Then read the log file with `manual-slop_read_file` or `grep` to find the relevant sections. The log file is your full record; you can search it without re-running.
+3. **Prefer targeted tier runs** (added 2026-06-27 per user directive). Do NOT run the full 11-tier batch for every verification. Run only the tiers relevant to the current task (e.g., `--tier tier3` or `--filter test_<specific_file>`). The full batch is for the USER to run after merge review, not for Tier 2's per-task verification. Running the full batch every time wastes 20+ minutes and the output is too large to be useful in context.
+4. **Default branch:** this repo uses `master` (not `main`). When fetching or branching, use `origin/master`. Do not assume `main` exists.
+5. **Line endings:** preserve existing line endings on edit. This repo has a mix of CRLF and LF; repo-wide LF standardization is a future track. For now, do not normalize.

+### 0. The Python Type Promotion Mandate (Added 2026-06-25)
+
+Every track spec/plan MUST respect the C11/Odin/Jai-in-Python mandate:
+- **No `dict[str, Any]` outside the wire boundary.** The boundary is 2-3 functions per file (TOML/JSON parse).
+- **No `Any` parameter, return, or field type.**
+- **No `Optional[T]` returns.** Use `Result[T]` + `NIL_T` sentinels per `conductor/code_styleguides/error_handling.md`.
+- **No `hasattr()` for entity type dispatch.** The boundary is typed Union dispatch or per-entity function overloads.
+- **Direct field access on typed `@dataclass(frozen=True, slots=True)` instances.**
+
+When a track's spec proposes lifting entities into `dict[str, Any]` or `Any`, Tier 1 MUST reject and rewrite. See `conductor/code_styleguides/data_oriented_design.md` §8.5 and `conductor/code_styleguides/python.md` §17 for the canonical mandate.

-**READ THIS BEFORE WRITING ANY PYTHON IN THIS REPO.** The project follows the
-data-oriented error handling convention (Ryan Fleury's "errors are
-just cases" framework). The convention is the OPPOSITE of idiomatic
-Python; LLMs are trained on idiomatic Python and will revert to it
-without explicit guidance. The convention prevents "tech rot with
-idiomatic Python."
+**READ THIS BEFORE WRITING ANY PYTHON IN THIS REPO.**
 
-**The 4 enforcement mechanisms (defense-in-depth):**
+### Core Value (Added 2026-06-25)
 
-1. **[`conductor/code_styleguides/error_handling.md`](../conductor/code_styleguides/error_handling.md)** — the canonical styleguide. 5 patterns, 3 boundary types, 1 broad-except distinction rule, 1 constructor-raise rule, 1 re-raise rule, and the audit script reference.
+**C11/Odin/Jai semantics in a Python runtime.** The project is written in Python because of practical constraints (time, dependencies, LLM codegen ability), but the convention is to make Python behave as close to a statically-typed value-typed language as the runtime allows.
 
-2. **[`conductor/code_styleguides/error_handling.md` "AI Agent Checklist"](../conductor/code_styleguides/error_handling.md#ai-agent-checklist-added-2026-06-16)** — the explicit cheatsheet of 5 MUST-DO rules, 7 MUST-NOT-DO rules, and 3 boundary patterns. Run this checklist before claiming a task is done.
+LLMs default to opaque types (`dict[str, Any]`, `Any`, `Optional[T]`, `hasattr()` polymorphism) because that's what idiomatic Python training data looks like. **That defaults to mediocrity. This rule overrides it.**
 
-3. **[`scripts/audit_exception_handling.py`](../../scripts/audit_exception_handling.py)** — the static analyzer. Catches violations before commit. Run it pre-commit. Has 3 output modes (human-readable, `--json`, `--by-size`) and a `--strict` CI-gate mode.
+The canonical mandate is in [`conductor/code_styleguides/data_oriented_design.md` §8.5](../conductor/code_styleguides/data_oriented_design.md#85-the-python-type-promotion-mandate-added-2026-06-25). The banned patterns are in [`conductor/code_styleguides/python.md` §17](../conductor/code_styleguides/python.md#17-banned-patterns-llm-default-anti-patterns-added-2026-06-25). The boundary-layer concept is in [`conductor/code_styleguides/type_aliases.md`](../conductor/code_styleguides/type_aliases.md).
 
-4. **The 4 enforcement audit scripts** — the project-level enforcement set:
-   - `scripts/audit_exception_handling.py --strict` (the convention)
-   - `scripts/audit_weak_types.py --strict` (the type-strengthening convention)
-   - `scripts/audit_main_thread_imports.py` (always strict; the import graph gate)
-   - `scripts/audit_no_models_config_io.py` (the config-I/O ownership gate)
+**Every section of this document, every styleguide in `conductor/code_styleguides/`, and every deep-dive guide in `docs/guide_*.md` MUST be read through the lens of this Core Value.** If a section suggests `dict[str, Any]`, `Any`, `Optional[T]`, or `hasattr()` for entity dispatch in non-boundary code, that's an anti-pattern; flag it and ask.
+
+### The 4 enforcement mechanisms (defense-in-depth)
+
+1. **[`conductor/code_styleguides/data_oriented_design.md`](../conductor/code_styleguides/data_oriented_design.md) §8.5 (The Python Type Promotion Mandate)** — the canonical mandate. Banned patterns: `dict[str, Any]`, `Any`, `Optional[T]`, `hasattr()` for entity dispatch, `getattr()` for type-dispatch, `.get()` on known fields.
+
+2. **[`conductor/code_styleguides/python.md`](../conductor/code_styleguides/python.md) §17 (LLM Default Anti-Patterns)** — the explicit cheatsheet. Each banned pattern has a before/after example.
+
+3. **[`conductor/code_styleguides/error_handling.md`](../conductor/code_styleguides/error_handling.md)** — the `Result[T]` + `NIL_T` convention. Replaces `Optional[T]` returns.
+
+4. **The enforcement audit scripts** — the project-level enforcement set:
+   - `scripts/audit_weak_types.py --strict` — flags `dict[str, Any]`, `Any`, anonymous tuples
+   - `scripts/audit_optional_returns.py --strict` — flags `Optional[T]` return types in ALL `src/*.py` (post-2026-06-27 successor to `audit_optional_in_3_files.py`)
+   - `scripts/audit_exception_handling.py --strict` — the data-oriented error handling convention
+   - `scripts/audit_main_thread_imports.py` — always strict; the import graph gate
+   - `scripts/audit_no_models_config_io.py` — the config-I/O ownership gate
+   - The boundary-layer audit (planned in `conductor/tracks/cruft_elimination_20260627/spec.md`) — documents every `Metadata` usage
 
 **Pre-commit workflow (recommended):**
 
 ```bash
 # Run before claiming "done"
-uv run python scripts/audit_exception_handling.py
 uv run python scripts/audit_weak_types.py
+uv run python scripts/audit_optional_returns.py
+uv run python scripts/audit_exception_handling.py
 uv run python scripts/audit_main_thread_imports.py
 uv run python scripts/audit_no_models_config_io.py
 ```
 
 **Why this is enforced:** the convention prevents the LLM-training-data
 problem. Without these mechanisms, AI agents writing new code will

The actual prompt construction lives in `run_worker_lifecycle` at `src/multi_agent_conductor.py` (the free function referenced by both `ConductorEngine.run` and the worker spawn flow).
+For meta-tooling sub-agent delegation (Tier 2 → Tier 3 / Tier 4 to do work on this repo), see `conductor/workflow.md` §"Conductor Token Firewalling" + the OpenCode Task tool (replaces the legacy mma_exec invocation).
 
 The "Token Firewall" effect — each worker starts with a clean context window — is achieved by the `ai_client.reset_session()` call at the start of `run_worker_lifecycle` (see [guide_mma.md](guide_mma.md) "Context Amnesia").
