Merge remote-tracking branch 'tier2-clone/tier2/default_layout_install_20260629' into tier2/default_layout_install_20260629

The previous fix (commit 5ab23f9e) used no_default_window to preserve
the INI's dock tree structure, but that left the dockspace NOT anchored
to the native window. When the user resized the window, the panels
stayed at fixed positions because the dockspace had a fixed size from
the INI (1680x1172).

Switch back to provide_full_screen_dock_space so HelloImGui creates a
full-screen dockspace that follows window resize. The live apply in
_post_init still runs (added in the previous fix) so the bundled INI's
window DockIds are applied to the dockspace.

Trade-off: with provide_full_screen_dock_space, HelloImGui creates its
own dockspace at runtime and discards the INI's DockNode tree (the
Split/X and child DockNodes). The INI's per-window DockIds are mapped
to the DockSpace (0xAFC85805) instead of specific DockNodes. Result:
all 8 panels dock as tabs in the central node of the dockspace, which
is at least anchored to the window.

The user's primary complaint was that panels did not follow window
resize (floating behavior). This change addresses that by anchoring
the dockspace to the native window. The 2-column split structure is a
follow-up that requires programmatic dock_builder usage to preserve
DockNodes when HelloImGui auto-creates the dockspace.

Verification (imgui.save_ini_settings_to_memory at runtime):
- All 8 windows docked with DockId=0xAFC85805,N (the DockSpace)
- DockSpace ID=0xAFC85805 ... CentralNode=1 (anchored to window)
- [Docking][Data] block fully preserved

+### 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.**

+
+### 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.
 
 ### 2. Use the more specific alias when the role is known
 
@@ -59,7 +84,42 @@ def append_comms(entry: CommsLogEntry) -> None: ...
 def get_history() -> History: ...
 ```
 
-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).
+
+### 2.5. When the role has stable distinct fields, promote it to its OWN dataclass
+
+**Added 2026-06-25 (correction to `metadata_promotion_20260624`).** When a sub-aggregate has a known set of stable, distinct fields (e.g., `CommsLogEntry` has `ts, role, kind, direction, model, source_tier, content, error`; `FileItem` has `path, view_mode, custom_slices`; `RAGChunk` has `id, document, path, score, metadata`), promote it to its OWN `@dataclass(frozen=True, slots=True)` with its OWN fields. 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 and the fields are heterogeneous (e.g., log entries from 5 different vendors with mutually-exclusive keys). Use `Metadata: Metadata` (the dataclass) as the catch-all — its 36 explicit fields cover the common wire schema, and its dict-compat methods allow ad-hoc keys for vendor-specific extensions. Do NOT use `dict[str, Any]` directly anywhere; `Metadata` is the typed replacement.
+
+**Canonical pattern (from `src/openai_schemas.py` and `src/type_aliases.py`):**
+
+```python
+@dataclass(frozen=True, slots=True)
+class CommsLogEntry:
+    ts: str = ""
+    role: str = ""
+    kind: str = ""
+    direction: str = ""
+    model: str = "unknown"
+    source_tier: str = "main"
+    content: Any = None
+    error: str = ""
+
+    def to_dict(self) -> Metadata:
+        return asdict(self)
+
+    @classmethod
+    def from_dict(cls, raw: Metadata) -> "CommsLogEntry":
+        valid = {f.name for f in fields(cls)}
+        return cls(**{k: v for k, v in raw.items() if k in valid})
+```
+
+**The rule (Tier 1 audit 2026-06-25):** if the original 2026-06-06 `data_structure_strengthening_20260606` design intent was per-concept promotion (it was — see `spec.md §3.3`: *"Phase 2 can convert `Metadata` to a `TypedDict` (or split into per-concept `TypedDict`s)..."*), the metadata_promotion_20260624 track must continue in that direction: per-aggregate dataclasses, not a shared mega-dataclass. The corrected design is in `conductor/tracks/metadata_promotion_20260624/spec.md` (rewrite of `G3`, `FR1`, and `Out of Scope` on 2026-06-25).
+
+**For a worked example of the per-aggregate pattern in production:** `src/openai_schemas.py` defines `ToolCall`, `ToolCallFunction`, `ChatMessage`, `UsageStats`, `NormalizedResponse` as separate frozen dataclasses — each with its own fields. `src/models.py:533` defines `FileItem` with paired `to_dict()` / `from_dict()` round-trip. `src/models.py:302` defines `Ticket` with 15 typed fields. These are the reference implementations.
 
 ### 3. Use `FileItems` for any list of file items

+## 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.

-You are running inside a Windows restricted token. The OpenCode permission system, the Windows ACL subsystem, and the git hooks in the clone are all enforcing the hard-ban list. A bypass of one layer is caught by another.
+STRICT SYSTEM DIRECTIVE: You are a Tier 2 Tech Lead in AUTONOMOUS mode, running in the **META-TOOLING** domain (per `docs/guide_meta_boundary.md`). This is NOT the manual-slop application's MMA engine — that's `src/multi_agent_conductor.py` in the APPLICATION domain. You are an AI agent orchestrating development of the manual_slop codebase.
+
+## MANDATORY: Domain Distinction (added 2026-06-27)
+
+This is the **META-TOOLING** layer — the AI orchestration that builds the manual_slop app. Distinct from the APPLICATION layer (the manual_slop app being built). When you see "sub-agent" or "Task tool" in this prompt, it means META-TOOLING sub-agent delegation (Tier 2 → Tier 3 / Tier 4 to do work on this repo). It is **distinct from** the application's MMA engine in `src/multi_agent_conductor.py`.
+
+## MANDATORY: Pre-Action Required Reading (added 2026-06-24 post-MCP-regression; updated 2026-06-27 with Core Value docs)
+
+Before ANY action (reading files, writing files, running commands, planning, executing, committing), the agent MUST read these files IN ORDER. Skipping any is grounds for aborting the work. This list exists because the 2026-06-24 MCP regression: Tier 2 made an empty fix commit, deleted `opencode.json` + `mcp_paths.toml`, and reported success without verifying — all because it did not read the prior `tier2_leak_prevention_20260620` track's spec.
+
+**TIER-1 BASELINE (the canonical rules — read these FIRST, in order):**
+
+1. `AGENTS.md` (project root) — the project operating rules + critical anti-patterns + HARD BANs (git restore/checkout/reset; opaque types in non-boundary code)
+2. `conductor/workflow.md` — the operational workflow + tier-specific conventions (TDD, per-task commits, failcount) + **§0 Python Type Promotion Mandate**
+3. `conductor/edit_workflow.md` — the edit tool contract (MUST use `manual-slop_edit_file`, NEVER native `Edit`)
+4. `conductor/tier2/githooks/forbidden-files.txt` — the file denylist (`opencode.json`, `mcp_paths.toml`, etc.)
+5. `conductor/tracks/tier2_leak_prevention_20260620/spec.md` — the prior leak incident + 3-layer defense (DO NOT REPEAT IT)
+6. `conductor/product-guidelines.md` — **the "Core Value" section at the top is mandatory reading** (C11/Odin/Jai-in-Python semantics; no `dict[str, Any]`, no `Any`, no `Optional[T]`, no `hasattr()` for entity dispatch, direct field access on typed dataclasses)
+7. `conductor/code_styleguides/data_oriented_design.md` §8.5 — the Python Type Promotion Mandate (the canonical rules)
+8. `conductor/code_styleguides/python.md` §17 — **LLM Default Anti-Patterns** (banned patterns with before/after; the most critical reference for implementation)
+9. `conductor/code_styleguides/type_aliases.md` — the type convention (Metadata is the boundary type, NOT `dict[str, Any]`)
+10. `conductor/code_styleguides/error_handling.md` — the `Result[T]` convention (replaces `Optional[T]`)
+11. The relevant `docs/guide_*.md` for the layer your track touches (especially `docs/guide_meta_boundary.md` for the meta-tooling/application split)
+
+**Do NOT be conservative about reading.** This project has extensive canonical documentation. LLMs of today are not good enough at predicting what this project wants — so read the docs. Being conservative about reading knowledge from markdown files is an ANTI-PATTERN in this codebase.
+
+**Enforcement:** the agent's first action in any new track must be to read all 11 files and acknowledge them in the commit message of the first commit (format: "TIER-2 READ <list> before <task>"). The failcount contract treats an unacknowledged first commit as a red-phase failure.
+
+## 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.
+
+## MANDATORY: Pre-Commit Verification Gate (added 2026-06-24)
+
+Before EVERY `git commit`, the agent MUST run all 3 of these checks:
+
+1. `git diff --cached --stat` — review for deletions (`-N` lines). If any file shows `-N`, ABORT the commit. Investigate whether the deletion is intentional work or a sandbox file leak.
+2. `uv run python scripts/audit_tier2_leaks.py --strict` — must exit 0. If it exits 1, the pre-commit hook should have caught the leak; investigate why it didn't.
+3. After `git commit`, run `git show HEAD --stat` and confirm the diff is non-empty AND matches your intended changes. **If the diff is empty, the sandbox hook silently stripped your commit — treat this as a HARD ERROR.** Investigate and re-commit correctly. Do NOT report success on an empty commit.
+
+This gate catches the failure mode in the 2026-06-24 MCP regression where Tier 2 made an empty fix commit (`2b7e2de1`) and reported success without verifying.
 
 ## Hard Bans (cannot run, enforced at 3 layers)
 
 - `git push*` (any push) - the user pushes the branch after review
 - `git checkout*` (any form) - use `git switch -c` for new branches, `git switch` to switch
-- `git restore*` (any form) - do not restore files
+- `git restore*` (any form) - do not restore files (per AGENTS.md hard ban)
 - `git reset*` (any form) - do not reset state
+- `git revert*` (any form) - per AGENTS.md hard ban. **THE TIMELINE IS IMMUTABLE**: when you fuck up a commit, you LIVE with the timeline and do a CORRECTION with a NEW commit. 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.
 
-## Conventions (MUST follow - added 2026-06-17)
+### 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.
+
+## Conventions (MUST follow - added 2026-06-17; updated 2026-06-27)
 
 - **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.
 - **Line endings:** preserve existing line endings on edit. This repo has a mix of CRLF and LF (a repo-wide LF standardization is a future track). If the file is CRLF, keep it CRLF. If the file is LF, keep it LF. Do not add CRLF to LF files or strip CRLF from CRLF files.
 - **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.

 - **Run-time expectation:** tracks are expected to take 1-4 hours. If the model reports it is running out of context or steps, do not stop. Note progress to disk (the failcount state file) and continue. The user expects autonomous runs to complete without manual intervention.
 - **Temp files** (added 2026-06-17, rewritten 2026-06-18, paths updated 2026-06-18 per Tier 2's project-relative relocation; deny patterns expanded 2026-06-19 to catch all env-var forms): All scratch, state, audit-output, and intermediate files MUST live INSIDE the Tier 2 clone. Default locations: `tests/artifacts/tier2_state/<track>/state.json` for failcount state, `tests/artifacts/tier2_failures/` for failure reports, `scripts/tier2/artifacts/<track>/` for throwaway scripts. **NEVER USE APPDATA** — the AppData tree is OFF-LIMITS for any read, write, or shell command. The bash deny rules enforce this; a violation halts the run. The full list of forbidden patterns (matched against the literal command string): `*AppData\\*`, `*AppData\Local\Temp\*`, `*$env:TEMP*`, `*$env:TMP*`, `*%TEMP%*`, `*%TMP%*`, `*GetTempPath*`, `*gettempdir*`, `*mkstemp*`. Do NOT attempt to use `$env:TEMP`, `$env:TMP`, `%TEMP%`, `%TMP%`, or any temp-dir API in any form — every one of those literal command strings is denied. Examples: `uv run python scripts/audit_exception_handling.py --json > tests/artifacts/tier2_state/audit_initial.json` (NOT `%TEMP%\audit_initial.json`; AppData is denied by the bash rule).

+**DEPRECATED (2026-06-27):** the legacy `scripts/mma_exec.py` and `scripts/claude_mma_exec.py` bridge scripts. All meta-tooling sub-agent delegation now goes through the **OpenCode Task tool** with the appropriate `subagent_type`:

 ## Failcount Contract
 
 After every task commit, you MUST check `should_give_up` from `scripts.tier2.failcount`. The state is persisted at `tests/artifacts/tier2_state/<track>/state.json` (project-relative; resolved via `Path(__file__).parents[2]` in the failcount module). The thresholds are:

The actual code changes are follow-up tracks (the 3 high-priority candidates from `decomposition_matrix.md`).
 
 The v2 audit's primary value is **cross-validation**: it consumes the JSON outputs of the 5 existing audit scripts and synthesizes them with the per-aggregate producer/consumer call graph. The result is a per-aggregate report that says "this aggregate has 12 weak-type sites (cross-checks `data_structure_strengthening`), 5 exception-handling sites (cross-checks `data_oriented_error_handling`), and 1 high-priority optimization candidate (decomposition direction: componentize)."

+
+10 phases, 13 tasks. Per-task atomic commits with git notes. TDD: each phase starts with the failing test, then implementation, then verification.
+
+## Step 0: Abort the SSDL campaign (5 file changes, prerequisite)
+
+Focus: Mark the failed SSDL campaign as cancelled before this track begins.
+
+- [x] Task 0.1 [Tier 1's ca219163]: Mark umbrella + 3 children as cancelled.
+  - WHERE: `conductor/tracks/metadata_ssdl_defusing_20260624/state.toml`, `conductor/tracks/metadata_nil_sentinel_20260624/state.toml`, `conductor/tracks/metadata_generational_handle_20260624/state.toml`, `conductor/tracks/metadata_field_cache_20260624/state.toml`
+  - WHAT: Set `status = "cancelled"` in each. Set all phases `cancelled` in each.
+  - HOW: `manual-slop_edit_file` for each
+  - SAFETY: Do NOT delete the 4 spec/plan/metadata files; preserve for audit trail
+  - COMMIT: `conductor(campaign-abort): metadata_ssdl_defusing_20260624 - SSDL campaign cancelled (premise was wrong; 4.01e22 is from dict[str, Any] type-dispatch, not nil-checks)`
+  - GIT NOTE: 1 campaign aborted; salvage NIL_METADATA primitive + 5 tests; the actual fix is any_type_componentization_reapply (per code_path_audit_phase_2_20260624)
+
+- [x] Task 0.2 [Tier 1's ca219163]: Write post-mortem.
+  - WHERE: `docs/reports/SSDL_CAMPAIGN_ABORTED_20260624.md` (NEW)
+  - WHAT: 1-page post-mortem documenting:
+    - The campaign's premise (6 nil-check functions in Metadata consumers)
+    - The verification that found 0 Metadata-typed nil-checks (the "6" was a static text string in `code_path_audit_gen.py:108`)
+    - The actual 73 nil-check functions across the codebase (most on `_gemini_client`, `path`, `adapter` — not Metadata)
+    - The 1 function Tier 2 migrated (`_build_files_section_from_items` in `src/aggregate.py`) was not actually a Metadata nil-check
+    - The budget gate (10% drop in `compute_effective_codepaths`) was mathematically near-impossible due to exponential dominance
+    - The real cause of 4.01e22: `dict[str, Any]` type-dispatch (123 `entry.get('key', default)` sites in Metadata consumers)
+    - The actual fix: `any_type_componentization_reapply_20260624` (this track)
+    - Salvage: `NIL_METADATA = {}` in `src/aggregate.py` + 5 tests in `tests/test_metadata_nil_sentinel.py` are kept as useful primitives
+  - HOW: Write the file

+

+  - WHERE: `src/mcp_client.py` (4 sites), `src/ai_client.py` (3 sites)

+    - Delete `MCP_TOOL_SPECS: list[dict[str, Any]] = [...]` declaration in `src/mcp_client.py` (~line 1972, large block)
+    - `src/mcp_client.py:2747`: `TOOL_NAMES: set[str] = {t['name'] for t in MCP_TOOL_SPECS}` → `TOOL_NAMES: set[str] = mcp_tool_specs.tool_names()`
+    - `src/ai_client.py:560, 582, 1012`: `mcp_client.TOOL_NAMES` → `mcp_tool_specs.tool_names()`

+
+## Phase 2: openai_schemas call-site migration (1 task, ~2-3 commits)
+
+Focus: Apply the 17 call-site migrations from parent plan §Phase 2. **Also removes the backward-compat `__init__` from `fix_test_failures_20260624`.**
+
+- [x] Task 2.1 [done in fix_test_failures_20260624]: Update `src/openai_compatible.py` to import from `src/openai_schemas.py` (already done).
+  - WHERE: `src/openai_compatible.py` (~12 sites)
+  - WHAT: Add `from src.openai_schemas import NormalizedResponse, OpenAICompatibleRequest, ChatMessage, UsageStats, ToolCall, ToolCallFunction`. Remove the local class definitions. Update internal consumers to use the new API (UsageStats, ChatMessage, ToolCall).
+  - HOW: `manual-slop_edit_file` for each site
+  - SAFETY: Run `tests/test_openai_compatible.py`, `tests/test_ai_client_*.py` after each site
+  - COMMIT: 1-2 commits
+
+- [x] Task 2.2 [20236546]: Update _send_gemini_cli (the 3 send_* in plan were already migrated; gemini_cli was the remaining one).
+  - WHERE: `src/ai_client.py`
+  - WHAT: Replace `usage_input_tokens=..., usage_output_tokens=...` with `usage=UsageStats(input_tokens=..., output_tokens=...)`. Replace `messages=[{"role": ..., "content": ...}]` with `messages=[ChatMessage(role=..., content=...)]`.

+  - COMMIT: 1 commit per function
+
+- [x] Task 2.3 [20236546]: Remove the backward-compat `__init__` from `src/openai_schemas.py`.
+  - WHERE: `src/openai_schemas.py` (the `NormalizedResponse.__init__` added by `fix_test_failures_20260624`)
+  - WHAT: Replace the custom `__init__` with the auto-generated one (`@dataclass(frozen=True) class NormalizedResponse` with fields `text, tool_calls, usage, raw_response` — no `init=False`)
+  - HOW: `manual-slop_py_update_definition` for `NormalizedResponse`
+  - SAFETY: The 12 tests that used `usage_input_tokens=...` should now use `usage=UsageStats(...)`. Update them in `tests/test_ai_client_tool_loop.py` + `tests/test_ai_client_tool_loop_builder.py` + `tests/test_ai_client_tool_loop_send_func.py` + `tests/test_ai_client_cli.py` + `tests/test_gemini_cli_*.py`.

+
+## Phase 3: provider_state call-site migration (1 task, ~5-7 commits)
+
+Focus: Remove 14 module globals from `src/ai_client.py`; use `get_history("...")` instead. Per-provider migration.
+
+- [x] Task 3.1 [deferred]: Snapshot pre-Phase-3 baseline (metric was captured post-phase; pre-baseline is in spec).
+  - WHERE: terminal
+  - WHAT: `uv run python scripts/audit_dataclass_coverage.py --json > /tmp/pre_phase3.json`
+  - SAFETY: This is the per-phase baseline. The parent plan's audit gate.
+
+- [x] Task 3.2 [25a22057]: Remove 14 module globals (lines 111-133) + add `from src.provider_state import get_history`.
+  - WHERE: `src/ai_client.py:111-133`
+  - WHAT: Delete the 12 (or 14) `_anthropic_history` + lock + ... + `_llama_history` + lock declarations. Add `from src.provider_state import get_history` at the top.
+  - HOW: `manual-slop_edit_file` (one big block delete + one line insert)
+  - SAFETY: This will break all 9 send_* functions. They must be updated per Task 3.3-3.7. Run `tests/test_provider_state.py` to verify the new module is intact.
+  - COMMIT: 1 commit (`refactor(ai_client): remove 14 module globals; use get_history(...) pattern`)
+

+# Track Specification: code_path_audit_phase_2_20260624
+
+## Overview
+
+The actual followup to `code_path_audit_20260607`. Three pieces of work, all measured on master `a18b8ad6`:
+
+1. **Re-apply the 48 `any_type_componentization_20260621` call-site migrations.** The 3 new modules (`src/mcp_tool_specs.py`, `src/openai_schemas.py`, `src/provider_state.py`) survived the revert at `751b94d4`; the call-site usages were reverted. The 4.01e22 combinatoric explosion (measured just now: 4.014e+22) is real and unchanged because `Metadata` is still `dict[str, Any]`. The fix is type promotion, not nil sentinels.
+2. **Address the 4 `INTERNAL_OPTIONAL_RETURN` pre-existing violations** (NG1 from `fix_test_failures_20260624`): `src/external_editor.py` (2), `src/session_logger.py` (1), `src/project_manager.py` (1).
+3. **Address the 7 `Optional[T]` return-type pre-existing violations** (NG2): `src/mcp_client.py:1285,1289` (2) + `src/ai_client.py:159,247,619,673,3115` (5).
+4. **Re-audit.** Measure the new combinatoric-explosion number after the 48 migrations. All 6 audit gates must pass `--strict` (the 2 failing gates today are NG1 + NG2 above).
+
+## Current State Audit (master `a18b8ad6`, just measured)
+
+| Metric | Value | Source |
+|---|---:|---|
+| `Metadata` consumers in `src/` | 751 | `code_path_audit.build_pcg` |
+| Total branches in Metadata consumers | 3,454 | `code_path_audit_ssdl.count_branches_in_function` |
+| **Effective codepaths (the 4.01e22)** | **4.014e+22** | `compute_effective_codepaths` |
+| Nil-check functions in Metadata consumers | 73 | `detect_nil_check_pattern` |
+| `MCP_TOOL_SPECS: list[dict[str, Any]]` in `src/mcp_client.py` | STILL EXISTS (45 dicts, not ToolSpec) | `git show master:src/mcp_client.py` |

+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | Phase 1 of parent `any_type_componentization_20260621` plan applied: `src/mcp_tool_specs.py` + 8 call-site migrations in `src/mcp_client.py` + `src/ai_client.py` | `mcp_client.MCP_TOOL_SPECS` replaced with `mcp_tool_specs.get_tool_schemas()`; 4 audit-gate-relevant assertions pass |
+| G2 | Phase 2 of parent plan: `src/openai_schemas.py` + 17 call-site migrations in `src/openai_compatible.py` + 3 send_* functions in `src/ai_client.py` | `src/ai_client.py` uses the new `usage: UsageStats` API; the 12 tests from `fix_test_failures_20260624` that depend on backward-compat continue to pass; the backward-compat `__init__` is REMOVED (no longer needed) |
+| G3 | Phase 3 of parent plan: `src/provider_state.py` + 41 call-site migrations in `src/ai_client.py` (remove 14 module globals, use `get_history(...)` instead) | 14 module globals removed from `src/ai_client.py`; no regression in `tests/test_provider_state.py` |
+| G4 | Phase 4 of parent plan: `src/log_registry.py` Session + SessionMetadata + 7 call-site migrations | `self.data: dict[str, Session]`; `tests/test_auto_whitelist_keywords` works (uses `dataclasses.replace`) |
+| G5 | Phase 5 of parent plan: `src/api_hooks.py` WebSocketMessage + 16 call-site migrations | `broadcast(WebSocketMessage(channel=..., payload=...))` everywhere; `_serialize_for_api -> JsonValue` |
+| G6 | NG1 fixed: 4 `INTERNAL_OPTIONAL_RETURN` violations in `src/external_editor.py`, `src/session_logger.py`, `src/project_manager.py` migrated to `Result[T]` | `audit_exception_handling --strict` (full src/) reports 0 violations |
+| G7 | NG2 fixed: 7 `Optional[T]` return types migrated (2 in `mcp_client.py:1285,1289`; 5 in `ai_client.py:159,247,619,673,3115`) | `audit_optional_in_3_files --strict` reports 0 violations |
+| G8 | Re-audit: effective-codepaths for `Metadata` drops by ≥ 2 orders of magnitude (target: 4.014e+22 → < 1e+20) | `compute_effective_codepaths` measured post-Phase-6 |
+| G9 | All 6 audit gates pass `--strict` | `weak_types`, `type_registry`, `main_thread_imports`, `no_models_config_io`, `code_path_audit_coverage`, `exception_handling` (full src/), `optional_in_3_files` |
+| G10 | Full test suite remains green (11/11 tiers PASS) | `scripts/run_tests_batched.py` |
+
+## Non-Goals
+
+- Modifications to the audit infrastructure (`src/code_path_audit*.py`); the campaign USES the audit to measure progress but does not change the audit
+- Reverting or extending the `metadata_ssdl_defusing_20260624` campaign (aborted; see Step 0 below)
+- The 73 `is None` / `== None` / `!= None` patterns in Metadata consumers (the SSDL campaign's wrong premise; the 4.01e22 is from `dict[str, Any]` type-dispatch, not nil-checks)
+- Refactoring the 7-file split in `src/code_path_audit*.py` (deferred; not this track's scope)
+- Runtime profiling (deferred; this track uses the static heuristic)
+
+## Step 0: Abort the SSDL campaign (prerequisite, 5 file changes)
+
+Before this track begins, the `metadata_ssdl_defusing_20260624` campaign must be marked cancelled:
+
+- `conductor/tracks/metadata_ssdl_defusing_20260624/state.toml`: `status = "cancelled"`, all 4 phases `cancelled`
+- `conductor/tracks/metadata_nil_sentinel_20260624/state.toml`: `status = "cancelled"` (already shipped; re-classify)
+- `conductor/tracks/metadata_generational_handle_20260624/state.toml`: `status = "cancelled"`, never started
+- `conductor/tracks/metadata_field_cache_20260624/state.toml`: `status = "cancelled"`, never started
+- `docs/reports/SSDL_CAMPAIGN_ABORTED_20260624.md`: NEW 1-page post-mortem
+
+**Salvage:** keep `NIL_METADATA = {}` in `src/aggregate.py` + the 5 tests in `tests/test_metadata_nil_sentinel.py` (useful primitives for future use).
+
+## Functional Requirements
+
+### FR1: Phase 1 (mcp_tool_specs)
+
+Per parent plan §Phase 1:
+- `tests/test_mcp_tool_specs.py` already exists (8 tests)
+- `src/mcp_tool_specs.py` already exists (the module)
+- Apply the 8 call-site migrations: `src/mcp_client.py` (4 sites: `native_names`, `res`, `MCP_TOOL_SPECS` declaration, `TOOL_NAMES`) + `src/ai_client.py` (3 sites: `mcp_client.TOOL_NAMES` × 3) + 1 site in `src/mcp_client.py:2747`
+
+### FR2: Phase 2 (openai_schemas)
+
+Per parent plan §Phase 2:
+- `src/openai_schemas.py` already exists
+- Apply the 17 call-site migrations: `src/openai_compatible.py` (~12 sites) + `_send_grok` + `_send_minimax` + `_send_llama` in `src/ai_client.py` (~5 sites)
+- **Remove the backward-compat `__init__`** added in `fix_test_failures_20260624` from `src/openai_schemas.py` (no longer needed; tests now use the new API)
+
+### FR3: Phase 3 (provider_state)
+
+Per parent plan §Phase 3:
+- `src/provider_state.py` already exists
+- Remove 14 module globals from `src/ai_client.py` (lines 111-133 per the parent plan)
+- Update ~27 call sites to use `get_history("...")` instead
+
+### FR4: Phase 4 (log_registry Session)
+
+Per parent plan §Phase 4:
+- `Session` and `SessionMetadata` already exist in `src/log_registry.py` (per the `git show` I just did)
+- Update the `self.data` type annotation and consumers (session_logger.py, log_pruner.py, gui_2.py)
+
+### FR5: Phase 5 (api_hooks WebSocketMessage)
+
+Per parent plan §Phase 5:
+- `WebSocketMessage` already exists in `src/api_hooks.py` (per earlier verification)
+- Update `broadcast` signature + ~5-10 callers
+- Update `_serialize_for_api` return type to `JsonValue`
+
+### FR6: NG1 fixups (4 violations)
+
+- `src/external_editor.py`: 2 `INTERNAL_OPTIONAL_RETURN` sites → migrate to `Result[T]`
+- `src/session_logger.py`: 1 `INTERNAL_OPTIONAL_RETURN` site → migrate
+- `src/project_manager.py`: 1 `INTERNAL_OPTIONAL_RETURN` site → migrate
+
+### FR7: NG2 fixups (7 violations)
+
+- `src/mcp_client.py:1285` `_get_symbol_node` → add `Result[T]` overload or use `Optional` only as arg
+- `src/mcp_client.py:1289` `find_in_scope` → same
+- `src/ai_client.py:159` `get_current_tier` → same
+- `src/ai_client.py:247` `get_comms_log_callback` → same
+- `src/ai_client.py:619` `get_bias_profile` → same
+- `src/ai_client.py:673` `_gemini_tool_declaration` → same
+- `src/ai_client.py:3115` `run_tier4_patch_callback` → same
+
+The migration pattern: add a `_result` helper that returns `Result[T]`; mark the existing function as backward-compat (return `data` from the result, errors discarded) OR fully migrate consumers.
+
+### FR8: Re-audit (G8)
+
+After all phases complete, re-run:
+```python
+from src.code_path_audit import build_pcg
+from src.code_path_audit_ssdl import compute_effective_codepaths
+pcg = build_pcg("src").data
+metadata_consumers = pcg.consumers.get("Metadata", [])
+total = sum(2 ** count_branches_in_function(f, "src") for f in metadata_consumers)
+print(f"Effective codepaths: {total:.3e}")
+```
+
+Target: < 1e+20 (2+ orders of magnitude drop from 4.014e+22).
+
+## Non-Functional Requirements
+
+- NFR1: 1-space indentation (per `conductor/workflow.md`)
+- 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 (per `error_handling.md`)
+- NFR7: No new `src/<thing>.py` files (per AGENTS.md)
+- NFR8: `tests/test_openai_compatible.py` must be updated to use the new `ChatMessage` and `ToolCall` attribute access (not backward-compat)
+
+## Architecture Reference
+
+- `conductor/code_styleguides/error_handling.md` — the Result[T] convention (the canonical reference for FR6)
+- `conductor/code_styleguides/type_aliases.md` — the 10 TypeAliases (the convention for naming)
+- `conductor/code_styleguides/data_oriented_design.md` — the canonical DOD reference (the "Prefer Fewer Types" principle that motivates FR1-FR5)
+- `conductor/tracks/any_type_componentization_20260621/plan.md` — the parent plan (the 6 phases for FR1-FR5)
+- `conductor/tracks/fix_test_failures_20260624/known_issues` — the 4 + 7 documented pre-existing violations (FR6, FR7)
+- `src/code_path_audit_ssdl.py` — `compute_effective_codepaths` (the measurement function for FR8)
+- `docs/reports/code_path_audit/2026-06-22/AUDIT_REPORT.md` — the original audit (the baseline for FR8)
+
+## Out of Scope
+
+- The 73 `is None` / `== None` / `!= None` patterns in Metadata consumers (proven to be a negligible fraction of the 4.01e22)
+- Modifications to the audit infrastructure
+- The 7-file split in `src/code_path_audit*.py`
+- Runtime profiling (deferred)
+- New top-level `src/<thing>.py` files (per AGENTS.md)
+

+## Risks
+
+| # | Risk | Likelihood | Mitigation |
+|---|---|---|---|
+| R1 | Phase 3 (provider_state) breaks concurrent `send_result()` calls from different threads (per `tests/test_ai_client_result.py` regression-guard tests) | medium | The parent plan's lock-migration pattern is correct; verify with the regression-guard tests after Phase 3 |
+| R2 | Phase 2 (openai_schemas) breaks 12 tests that depended on the backward-compat `__init__` from `fix_test_failures_20260624` | low | The 12 tests use the old API; after the call-site migration, they should use the new API. Update the tests in Phase 2 to use `usage=UsageStats(...)` instead of `usage_input_tokens=...` |
+| R3 | The 48 migrations produce a smaller drop than expected (e.g., 4.014e+22 → 4.013e+22 instead of < 1e+20) | low | The combinatoric explosion IS from `dict[str, Any]`; the migration eliminates the explosion. If the drop is smaller, the audit infrastructure may have a bug (separate investigation) |
+| R4 | Removing the 14 module globals in `src/ai_client.py` requires updating 27 call sites in a way that introduces bugs | medium | Per-provider migration (5 commits, one per vendor) with regression-guard tests after each |
+| R5 | The NG1 + NG2 migrations introduce regressions in 11 specific functions | medium | Add a behavioral test per migration; verify with `scripts/run_tests_batched.py` after Phase 7 + 8 |

+# Tier 2 Startup Brief: code_path_audit_phase_3_provider_state_20260624
+
+## Context
+
+This is the migration track for `code_path_audit_phase_2_20260624`. Phase 2 made `src/aggregate.py`'s `_build_files_section_from_items` use `NIL_METADATA` (good) and added a 12-module-globals alias layer to `src/ai_client.py` (partial — those aliases need to be removed and the 26 call sites migrated to `provider_state.get_history("...")` directly).
+
+The previous review (`docs/reports/REVIEW_TIER2_code_path_audit_phase_2_20260624.md`) flagged this as the actual fix for VC2 + the missing structural work. VC5 (the 4.01e22 metric) is NOT addressed by this track — that requires type promotion, which is the grandparent track's scope.

+
+## ProviderHistory interface (post-cc7993e5, post-cc7993e5)
+
+```python
+# src/provider_state.py
+@dataclass
+class ProviderHistory:
+    messages: list[HistoryMessage] = field(default_factory=list)
+    lock: threading.RLock = field(default_factory=threading.RLock)
+
+    def __bool__(self) -> bool: ...           # acquires lock
+    def __len__(self) -> int: ...             # acquires lock
+    def __iter__(self): ...                   # acquires lock
+    def __getitem__(self, idx): ...          # acquires lock
+    def append(self, message): ...            # acquires lock
+    def get_all(self) -> list[HistoryMessage]: ...  # acquires lock
+    def replace_all(self, messages): ...      # acquires lock
+    def clear(self) -> None: ...              # acquires lock
+
+_PROVIDER_HISTORIES: dict[str, ProviderHistory] = { "anthropic": ..., "deepseek": ..., ... }
+
+def get_history(provider: str) -> ProviderHistory: ...
+def clear_all() -> None: ...
+```
+
+**Critical:** `lock` is `RLock` (re-entrant). The dunders acquire the lock. Calling `len(history)` while inside `with history.lock:` is SAFE (re-entrant).
+
+## Migration pattern
+
+```python
+# BEFORE (alias pattern):
+with _anthropic_history_lock:
+    if not _anthropic_history:
+        ...
+    for msg in _anthropic_history:
+        ...
+    _anthropic_history.append(msg)
+
+# AFTER (direct pattern):
+history = provider_state.get_history("anthropic")
+with history.lock:
+    if not history:
+        ...
+    for msg in history:
+        ...
+    history.append(msg)
+```
+
+**Capture to local `history` variable** for readability AND to minimize lock acquisitions (the dunder methods re-acquire the lock each call). Inside a `with history.lock:` block, calling `history.append(...)` is re-entrant — no additional cost.
+
+## Per-provider pattern
+
+For each of the 6 providers (anthropic, deepseek, minimax, qwen, grok, llama):
+- Replace `_X_history` with `provider_state.get_history("X")` (or local `history = provider_state.get_history("X")`)
+- Replace `_X_history_lock` with `.lock` attribute
+- Replace `for msg in _X_history` with `for msg in history` (or `for msg in provider_state.get_history("X")`)
+- Replace `_X_history.append(msg)` with `history.append(msg)`
+- Replace `_X_history.clear()` with `history.clear()` (in `cleanup()` — see below)
+
+## cleanup() function (Phase 7)
+
+```python
+# BEFORE:
+def cleanup():
+    with _anthropic_history_lock:
+        _anthropic_history.clear()
+    with _deepseek_history_lock:
+        _deepseek_history.clear()
+    # ... 5 more blocks ...
+    # Plus reset of SDK clients (separate concerns)
+
+# AFTER:
+def cleanup():
+    provider_state.clear_all()
+    # Plus reset of SDK clients (separate concerns)
+```
+
+## Acceptance per phase
+
+- **Phase 0:** `tests/test_provider_state_migration.py` exists, 12+ tests pass.
+- **Phases 1-6 (per-provider):** all relevant per-provider test files pass; 0 hits for `_X_history` in `git grep` for the migrated provider.
+- **Phase 7:** 0 hits for `_X_history:` declarations; `cleanup()` uses `provider_state.clear_all()`.
+- **Phase 8:** 7/7 audit gates pass; 10/11 batched tiers PASS; `TRACK_COMPLETION` written.
+
+## Pre-flight: verify the baseline
+
+```bash
+# Verify provider_state uses RLock (post-cc7993e5)
+git show HEAD:src/provider_state.py | grep "RLock"
+# Expect: threading.RLock
+
+# Verify the 12 aliases are present (pre-migration)
+git show HEAD:src/ai_client.py | grep -E "_anthropic_history = |_deepseek_history = "
+# Expect: 6 hits (one per provider)
+
+# Verify the 26 call sites (pre-migration)
+git grep -E "_anthropic_history\b|_deepseek_history\b|_minimax_history\b|_qwen_history\b|_grok_history\b|_llama_history\b" HEAD -- src/ai_client.py | wc -l
+# Expect: ~26
+```
+
+## Post-flight: verify the migration
+
+```bash
+# After all 7 phases: 0 hits for _X_history
+git grep -E "_anthropic_history\b|_deepseek_history\b|_minimax_history\b|_qwen_history\b|_grok_history\b|_llama_history\b" HEAD -- src/ai_client.py
+# Expect: (no output)
+
+# provider_state usage count increases
+git grep "provider_state.get_history" HEAD -- src/ai_client.py | wc -l
+# Expect: ~30+ (was 6 for the aliases)

+# Plan: code_path_audit_phase_3_provider_state_20260624
+
+7 phases, 8 tasks, 7 atomic commits. Per-task TDD red-first. Tier 3 workers execute. Tier 2 reviews per phase.
+
+## Phase 0: Pre-flight verification (Tier 1, 0 commits)
+
+**Focus:** Verify the baseline + set up `tests/test_provider_state_migration.py` as the regression-guard.
+
+- [x] **Task 0.1** [already done in c6b9d5fa]: Verify `provider_state.ProviderHistory` uses `RLock` (post-cc7993e5).
+- [x] **Task 0.2** [already done]: 7 audit gates pass `--strict`; 10/11 batched tiers PASS.
+- [x] **Task 0.3** [Tier 3]: Create `tests/test_provider_state_migration.py` with the regression-guard pattern:
+  - For each of the 6 providers: instantiate `provider_state.get_history("X")`, call `.append(msg)`, call `.get_all()`, assert ordering preserved.
+  - For each of the 6 providers: instantiate `provider_state.get_history("X")`, call `.lock` in a `with:` block, call `len()`, `.append()`, assert no deadlock.
+  - For thread-safety: spawn 2 threads each calling `append` 100 times, assert all 200 messages present and ordered.
+  - **TDD:** this test file should PASS on the current state (the migration hasn't happened yet — the aliases still work, so ProviderHistory API is reachable).
+- [x] **COMMIT:** `test(provider_state): add migration regression-guard suite` [4e94780] (Tier 3)
+- [x] **GIT NOTE:** Phase 0 is the baseline. The 6 per-provider migration commits are atomic and tested against this suite.
+
+## Phase 1: Migrate anthropic (1 task, 1 commit)
+
+**Focus:** 10 sites in `_send_anthropic` (lines 1452-1591) — the highest-traffic provider.
+
+- [x] **Task 1.1** [Tier 3]:
+  - WHERE: `src/ai_client.py` lines 1452, 1456, 1466, 1467, 1468, 1469, 1478, 1480, 1484, 1498, 1512, 1515, 1591 (~13 sites; some inside nested defs)
+  - WHAT: replace all `_anthropic_history` references with `provider_state.get_history("anthropic")` (capture to local `history` variable for readability)
+  - HOW: `manual-slop_edit_file` per site. Use `history = provider_state.get_history("anthropic")` inside the `with history.lock:` block (or before the iteration if no lock block)
+  - SAFETY: Run `tests/test_anthropic_*` + `tests/test_ai_client_result` + `tests/test_ai_client_tool_loop*` + `tests/test_provider_state_migration.py` after the change
+- [x] **COMMIT:** `refactor(ai_client): migrate _anthropic_history call sites to provider_state.get_history("anthropic")` [2323b52] (Tier 3, atomic)
+- [x] **GIT NOTE:** 13 sites migrated. The local `history` variable pattern is used inside `with history.lock:` blocks to minimize lock acquisitions.
+
+## Phase 2: Migrate deepseek (1 task, 1 commit)
+
+**Focus:** 6 sites in `_send_deepseek` + `_repair_deepseek_history` (lines 2211-2430) — the deadlock-prone provider.
+
+- [x] **Task 2.1** [Tier 3]:
+  - WHERE: `src/ai_client.py` lines 2211, 2217, 2231, 2363, 2370, 2428, 2430 (~7 sites; nested in `_send_deepseek` and tool_result handling)
+  - WHAT: replace `_deepseek_history` and `_deepseek_history_lock` with `provider_state.get_history("deepseek")` + `.lock`
+  - HOW: `manual-slop_edit_file` per site
+  - SAFETY: Run `tests/test_deepseek_provider` (7 tests) + `tests/test_ai_client_tool_loop*` + `tests/test_provider_state_migration.py`
+  - **CRITICAL:** This is the deadlock-prone site (the one that prompted `cc7993e5`). The RLock fix in `provider_state` MUST remain in place. The `with history.lock:` pattern in the migrated code must acquire the SAME `RLock` instance that `_deepseek_history_lock` aliased to.
+- [x] **COMMIT:** `refactor(ai_client): migrate _deepseek_history call sites to provider_state.get_history("deepseek")` [79d0a56] (Tier 3, atomic)
+- [x] **GIT NOTE:** 7 sites migrated. The RLock re-entrance is critical here (the inner `_repair_deepseek_history` does `history[-1]` inside the same `with` block). Verified by `tests/test_deepseek_provider::test_deepseek_completion_logic` which exercises this exact call path.
+
+## Phase 3: Migrate grok (1 task, 1 commit)
+
+**Focus:** 2 sites in `_send_grok` (lines 2586-2597) — the X.AI provider.
+
+- [x] **Task 3.1** [Tier 3]:
+  - WHERE: `src/ai_client.py` lines 2586, 2593, 2595, 2597 (~4 sites)
+  - WHAT: replace `_grok_history` and `_grok_history_lock`
+  - HOW: `manual-slop_edit_file` per site
+  - SAFETY: Run `tests/test_grok_provider` (4 tests) + `tests/test_provider_state_migration.py`
+- [x] **COMMIT:** `refactor(ai_client): migrate _grok_history call sites to provider_state.get_history("grok")` [94a136c] (Tier 3, atomic)
+- [x] **GIT NOTE:** 4 sites migrated. The 2 distinct call patterns (separate `with` blocks for each `if` branch) consolidated to the canonical pattern.
+
+## Phase 4: Migrate minimax (1 task, 1 commit)
+
+**Focus:** 2 sites in `_send_minimax` (lines 2673-2676) — the MiniMax provider.
+
+- [x] **Task 4.1** [Tier 3]:
+  - WHERE: `src/ai_client.py` lines 2674, 2676, 2678
+  - WHAT: replace `_minimax_history` and `_minimax_history_lock`
+  - HOW: `manual-slop_edit_file` per site
+  - SAFETY: Run `tests/test_minimax_provider` (4 tests) + `tests/test_provider_state_migration.py`
+- [x] **COMMIT:** `refactor(ai_client): migrate _minimax_history call sites to provider_state.get_history("minimax")` [7d2ce8f] (Tier 3, atomic)
+- [x] **GIT NOTE:** 3 sites migrated.
+
+## Phase 5: Migrate qwen (1 task, 1 commit)
+
+**Focus:** 2 sites in `_send_qwen` (lines 2826-2835) — the DashScope provider.
+
+- [x] **Task 5.1** [Tier 3]:

+  - WHAT: replace `_qwen_history` and `_qwen_history_lock`

+- [x] **COMMIT:** `refactor(ai_client): migrate _qwen_history call sites to provider_state.get_history("qwen")` [81e013d] (Tier 3, atomic)
+- [x] **GIT NOTE:** 3 sites migrated.
+
+## Phase 6: Migrate llama (1 task, 1 commit)
+
+**Focus:** 4 sites in `_send_llama` (lines 2916-3029) — the local llama.cpp / Ollama provider.
+
+- [x] **Task 6.1** [Tier 3]:
+  - WHERE: `src/ai_client.py` lines 2916, 2923, 2925, 2927, 3010, 3012, 3014, 3025, 3029 (~9 sites; spread across 2 separate `_send_llama` functions for OpenRouter vs Ollama backends)
+  - WHAT: replace `_llama_history` and `_llama_history_lock`
+  - HOW: `manual-slop_edit_file` per site
+  - SAFETY: Run `tests/test_llama_provider` (5 tests) + `tests/test_llama_ollama_native` (5 tests) + `tests/test_provider_state_migration.py`
+- [x] **COMMIT:** `refactor(ai_client): migrate _llama_history call sites to provider_state.get_history("llama")` [fd56613] (Tier 3, atomic)
+- [x] **GIT NOTE:** 9 sites migrated. Both backend functions (OpenRouter + Ollama) share the same `provider_state.get_history("llama")` instance.
+
+## Phase 7: Remove the 12 module-level aliases + cleanup() (1 task, 1 commit)
+
+**Focus:** Delete lines 113-135 (the 12 module-level aliases) + simplify the `cleanup()` function.
+
+- [x] **Task 7.1** [Tier 3]:
+  - WHERE: `src/ai_client.py` lines 113-135 (the 12 module-level aliases)
+  - WHAT: delete the 12 alias declarations. Replace the 7 lock-guarded clears in `cleanup()` with a single `provider_state.clear_all()` call
+  - HOW: `manual-slop_edit_file` (one big block delete + one line insert in `cleanup()`)
+  - SAFETY: Run `tests/test_provider_state_migration.py` + all 7 per-provider test files. The `clear_all()` call iterates `_PROVIDER_HISTORIES.values()` and calls `.clear()` on each (with the RLock acquired per-history). Semantically equivalent to the 7 separate `with _X_history_lock: _X_history.clear()` blocks.
+- [x] **COMMIT:** `refactor(ai_client): remove 12 module-level provider_state aliases; cleanup() uses clear_all()` [da66adf] (Tier 3, atomic)
+- [x] **GIT NOTE:** 12 module-level aliases deleted. The 7 lock-guarded clears in `cleanup()` consolidated to a single `provider_state.clear_all()` call. Net diff: -10 lines (12 alias deletions - 2 added imports/comments).
+
+## Phase 8: Verification + end-of-track (1 task, 3 commits)
+
+**Focus:** Run all 8 VCs; write `TRACK_COMPLETION`; update `state.toml` + `tracks.md`.
+
+- [x] **Task 8.1** [Tier 2]:
+  - WHERE: terminal + `docs/reports/TRACK_COMPLETION_code_path_audit_phase_3_provider_state_20260624.md` (NEW)
+  - WHAT:
+    - VC1-VC8 verification (see spec.md §Verification Criteria)
+    - Re-measure effective codepaths: expected UNCHANGED at 4.014e+22 (the migration removes 1 branch from `cleanup()` only; not visible in 2^N sum)
+    - Run the full 7 audit gates + batched test suite
+    - Document the result: 10/11 tiers PASS (1 pre-existing RAG flake); 7/7 audit gates PASS
+    - Document why VC7 (effective codepaths) didn't change: the metric is dominated by `2^N` for the highest-branch-count functions; removing 1 branch from 1 function changes the total by < 0.01%
+  - HOW: Run each command, capture output, write the report
+  - COMMIT: 3 commits: state, TRACK_COMPLETION, tracks.md update
+  - VERIFY: All 8 VCs pass

+
+## Notes for Tier 3 workers
+
+- **Pattern consistency:** For each site, the canonical pattern is `history = provider_state.get_history("X"); ... use history.append(...) ...`. Capture to a local variable if the same provider is used 3+ times in a function.
+- **Lock acquisition:** Inside `with history.lock:` blocks, the lock is already held; subsequent `history.append(...)` etc. will use the same RLock instance (re-entrant — no deadlock).
+- **Indentation:** 1-space per level (project standard). Use `manual-slop_edit_file` for surgical edits.
+- **No comments:** per AGENTS.md "No comments in source code."
+- **No new imports:** the `from src import provider_state` is already at the top of `src/ai_client.py`.
+
+## Notes for Tier 2 reviewer
+
+- After each per-provider commit, run the full batched test suite to catch any unexpected regressions (thread-safety tests, RAG engine init, etc.).
+- The RLock re-entrance is the critical correctness property. If any test that previously DEADLOCKed now passes — that's the signal the migration is correct.
+- If a per-provider commit causes a regression, **revert** the commit and investigate (don't try to fix forward; the prior state is the known-good baseline).

+# Track Specification: code_path_audit_phase_3_provider_state_20260624
+
+## Overview
+
+The actual fix for the 4 NG2 violations and 1 partial NG2 violation left by `code_path_audit_phase_2_20260624` (the previous Tier 2 work). Phase 2 made `src/aggregate.py`'s `_build_files_section_from_items` use `NIL_METADATA` (good), but the actual fix for the 27 alias-based call sites in `src/ai_client.py` was deferred. This track fully migrates the 27 call sites from `_X_history` aliases to direct `provider_state.get_history("...").get_all()` / `.append(...)` / `with get_history("...").lock:` patterns.
+
+## Current State Audit (master `22c76b95`, measured 2026-06-24)
+
+| Metric | Value | Source |
+|---|---:|---|
+| `_anthropic_history` aliases in `src/ai_client.py` | 1 module-level alias + 10 call sites | `git grep` |
+| `_deepseek_history` aliases | 1 + 6 call sites | `git grep` |
+| `_minimax_history` aliases | 1 + 2 call sites | `git grep` |
+| `_qwen_history` aliases | 1 + 2 call sites | `git grep` |
+| `_grok_history` aliases | 1 + 2 call sites | `git grep` |
+| `_llama_history` aliases | 1 + 4 call sites | `git grep` |
+| **Total module-level aliases** | 6 `_X_history` + 6 `_X_history_lock` (12 module globals) | `git show HEAD:src/ai_client.py | head -140` |
+| **Total call sites** | 26 references to `_X_history` (not counting the alias declarations) | `git grep` |
+| Lock pattern usages | 12 `with _X_history_lock:` blocks | `git grep` |
+| Effective codepaths (4.014e+22) | UNCHANGED (Phase 2 did not address) | `src/code_path_audit_ssdl.compute_effective_codepaths` |
+| `provider_state.ProviderHistory` | Uses `threading.RLock` (post-cc7993e5 deadlock fix) | `src/provider_state.py:29` |
+
+### Why this matters
+
+The aliases `_anthropic_history = provider_state.get_history("anthropic")` mean consumers still use the bare variable name. The aliases work functionally (they reference the same `ProviderHistory` instance), but:
+1. **The structural goal is not met** — `provider_state` was supposed to ENCAPSULATE the per-provider state behind a 4-method interface. The aliases break the encapsulation by exposing the bare `ProviderHistory` as a module-level name.
+2. **The 4 NG2 (`Optional[T]` return-type) violations are still partially unresolved** — the legacy wrappers like `get_current_tier()` are at 1-space module-level; the canonical `get_current_tier_result()` exists but the bare name still appears in some callsites. The aliases mirror this pattern.
+3. **The 4.01e22 combinatoric explosion is unchanged** — the metric is dominated by `2^branches` for the highest-branch-count functions. Removing 1 branch from 1 function changes the total by < 0.01%. The structural improvement is in API surface (typed `ProviderHistory` + `RLock` + re-entrant dunders), but the actual combinatoric reduction requires reducing `dict[str, Any]` type-dispatch branches. THAT is the parent plan's goal, deferred.
+4. **The `T | None` workaround in 4 legacy wrappers** is technically compliant (the audit only flags `Optional[T]` AST subscripts) but is a heuristic bypass of the convention's spirit. Migrating to `_result()` pattern + consumers is the proper fix.
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | Remove all 12 module-level aliases in `src/ai_client.py` (lines 113-135) | `git grep "_anthropic_history:\|_anthropic_history = provider_state" master:src/ai_client.py` returns 0 hits |
+| G2 | Migrate all 26 call sites to use `provider_state.get_history("...")` directly | `git grep -E "_anthropic_history\b\|_deepseek_history\b\|_minimax_history\b\|_qwen_history\b\|_grok_history\b\|_llama_history\b" master:src/ai_client.py` returns 0 hits |
+| G3 | Per-provider migration (6 vendors, 1 commit each) | 6 atomic commits, one per vendor, each with regression-guard tests |
+| G4 | Add `tests/test_provider_state_migration.py` — verify no regression | All 12 `test_provider_state` tests pass + 7 `test_deepseek_provider` + 5 `test_anthropic` + 4 `test_grok_provider` + 4 `test_minimax_provider` + 5 `test_qwen_provider` + 6 `test_llama_provider` + 1 `test_llama_ollama_native` |
+| G5 | `cleanup()` function uses `provider_state.clear_all()` | `git grep "_anthropic_history = \[\]\|_anthropic_history_lock" master:src/ai_client.py` returns 0 hits |
+| G6 | All 7 audit gates pass `--strict` (no regression) | `weak_types` 102 ≤ 112; `type_registry` 23 files; `main_thread_imports` 17 files; `no_models_config_io` 0; `code_path_audit_coverage` 0; `exception_handling` 0; `optional_in_3_files` 0 |
+| G7 | Full test suite remains green (10/11 tiers PASS — same as before) | `scripts/run_tests_batched.py` → 10/11 PASS, 1 pre-existing RAG flake |
+
+## Non-Goals
+
+- Modifications to `src/provider_state.py` (the migration is on the consumer side; the ProviderHistory interface is already correct after `cc7993e5`).
+- The 4 NG1 (`INTERNAL_OPTIONAL_RETURN`) violations in `external_editor.py` + `session_logger.py` + `project_manager.py` — already addressed in Phase 2 by `ee4287ae`.
+- The 4 `T | None` legacy wrappers — these are technically compliant per the audit. The bypass is documented in `docs/reports/REVIEW_TIER2_code_path_audit_phase_2_20260624.md` "Finding 8" as a followup. Defer to a separate track.
+- The 4.01e22 combinatoric explosion — the actual fix is type promotion (`dict[str, Any]` → typed dataclass), which is the parent `any_type_componentization_20260621` track. Phase 2 + Phase 3 only address the API surface, not the type-dispatch branches.
+- RAG test flake (`test_rag_phase4_final_verify`) — pre-existing, Windows-specific (sentence_transformers download / chroma lock); out of scope.
+
+## Functional Requirements
+
+### FR1: Remove the 12 module-level aliases (lines 113-135)
+
+```python
+# DELETE lines 113-135 of src/ai_client.py
+_anthropic_history = provider_state.get_history("anthropic")
+_anthropic_history_lock = _anthropic_history.lock
+
+_deepseek_history = provider_state.get_history("deepseek")
+_deepseek_history_lock = _deepseek_history.lock
+
+# ... (minimax, qwen, grok, llama) ...
+```
+
+The aliases become unused. The 7 SDK client holders (`_anthropic_client`, `_deepseek_client`, etc.) are NOT deleted — they stay as module-level `Any` variables per Phase 2 spec ("SDK client holders stay as module-level `Any` variables per Pattern 3 (heterogeneous SDK types, lazy-initialized). Only the homogeneous history aspect is unified.").
+
+### FR2: Per-provider migration (6 vendors)
+
+For each provider, replace `_X_history` with `provider_state.get_history("X")` + the appropriate dunder or method call:
+
+| Pattern | Replacement |
+|---|---|
+| `for msg in _X_history:` | `for msg in provider_state.get_history("X"):` |
+| `if not _X_history:` | `if not provider_state.get_history("X"):` |
+| `_X_history.append(msg)` | `provider_state.get_history("X").append(msg)` |
+| `with _X_history_lock:` | `with provider_state.get_history("X").lock:` |
+| `_X_history[i]`, `_X_history[-1]`, `_X_history[:n]` | `provider_state.get_history("X")[i]`, etc. |
+| `len(_X_history)` | `len(provider_state.get_history("X"))` |
+| `for msg in _X_history:` (inside the `with lock:` block) | `_X_history_local = provider_state.get_history("X"); for msg in _X_history_local:` (capture once to avoid repeated lock acquisitions) |
+
+**Optimization:** for tight loops or repeated accesses, capture the history to a local variable once:
+```python
+history = provider_state.get_history("anthropic")
+for msg in history:
+    ...
+history.append(...)
+```
+
+This is more readable AND avoids 2-3 lock acquisitions per iteration.
+
+### FR3: Per-provider commit structure
+
+| Commit | Provider | Site count | Verification |
+|---|---|---|---|
+| 1 | anthropic | 10 sites (lines 1452-1591) | `test_anthropic_*` + `test_ai_client_result` pass |
+| 2 | deepseek | 6 sites (lines 2211-2430) | `test_deepseek_provider` (7 tests) + `test_ai_client_tool_loop*` pass |
+| 3 | minimax | 2 sites (lines 2673-2676) | `test_minimax_provider` (4 tests) pass |
+| 4 | qwen | 2 sites (lines 2826-2835) | `test_qwen_provider` (5 tests) pass |
+| 5 | grok | 2 sites (lines 2586-2597) | `test_grok_provider` (4 tests) pass |
+| 6 | llama | 4 sites (lines 2916-3029) | `test_llama_provider` (5 tests) + `test_llama_ollama_native` (5 tests) pass |
+
+Each commit: 1 file (`src/ai_client.py`), 1 per-provider pattern, regression-guard test run.
+
+### FR4: `cleanup()` function uses `provider_state.clear_all()`
+
+Currently (lines 463-499 in `src/ai_client.py`):
+```python
+with _anthropic_history_lock:
+    _anthropic_history.clear()
+# ... 5 more similar blocks for deepseek, minimax, qwen, grok, llama ...
+```
+
+Replace with:
+```python
+provider_state.clear_all()
+```
+
+Single call. Less code, same behavior.
+
+### FR5: Re-audit (G6)
+
+After all 6 per-provider commits + the cleanup() commit:
+```bash
+uv run python -c "from src.code_path_audit import build_pcg; from src.code_path_audit_ssdl import compute_effective_codepaths, count_branches_in_function; pcg = build_pcg('src').data; total = sum(2 ** count_branches_in_function(f, 'src') for f in pcg.consumers.get('Metadata', [])); print(f'{total:.3e}')"
+```
+
+Expected: same 4.014e+22 (no combinatoric reduction; the metric is dominated by 2^N). Document the unchanged number in the end-of-track report.
+
+## Non-Functional Requirements
+
+- NFR1: 1-space indentation (per `conductor/workflow.md`)
+- 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 (per `error_handling.md`)
+- NFR7: No new `src/<thing>.py` files (per AGENTS.md)
+
+## Architecture Reference
+
+- `conductor/code_styleguides/error_handling.md` — the `Result[T]` convention (the reference for the NG2 wrappers)
+- `conductor/code_styleguides/data_oriented_design.md` — the "Prefer Fewer Types" principle (motivates Phase 3)
+- `conductor/tracks/code_path_audit_phase_2_20260624/spec.md` — the parent plan (where the aliases were introduced)
+- `conductor/tracks/any_type_componentization_20260621/plan.md` — the grandparent plan (the 27 call sites came from the parent plan's 48 call-site migrations)
+- `src/code_path_audit_ssdl.py` — `compute_effective_codepaths` (the measurement function for FR5)
+- `src/provider_state.py` — the ProviderHistory interface (post-cc7993e5: RLock, removed copy-paste bugs)
+- `src/ai_client.py:113-135` — the 12 module-level aliases to be removed
+- `src/ai_client.py:1452-1591, 2211-2430, 2586-2597, 2673-2676, 2826-2835, 2916-3029` — the 26 call sites per provider
+- `docs/reports/REVIEW_TIER2_code_path_audit_phase_2_20260624.md` — the review that identified the partial work + the R4 fabrication
+
+## Out of Scope
+
+- Modifications to `src/provider_state.py` (the migration is on the consumer side; ProviderHistory interface is already correct)
+- The 4 `T | None` legacy wrappers (technically compliant per the audit; documented bypass; defer to followup track)
+- The 4.01e22 combinatoric explosion (requires type promotion, not alias removal; grandparent plan scope)
+- RAG test flake (`test_rag_phase4_final_verify`) — pre-existing, Windows-specific
+- New `src/<thing>.py` files (per AGENTS.md hard rule)
+

+## Risks
+
+| # | Risk | Likelihood | Mitigation |
+|---|---|---|---|
+| R1 | Migration breaks the regression-guard tests (`test_ai_client_result` for thread-safety, `test_provider_state` for ProviderHistory API) | medium | Per-provider commits with regression-guard test runs after each; revert + fix if any test fails |
+| R2 | The `for msg in _X_history` pattern inside `with _X_history_lock:` is missed during migration → 2 different lock-acquisition patterns interleaved | low | Capture `_X_history` to a local variable once: `history = provider_state.get_history("X"); for msg in history: ...` inside the `with history.lock:` block |
+| R3 | Some sites use `_X_history` inside a function that ALSO has `_X_history_lock` as a parameter (not just the alias) | low | Search for `_X_history_lock` as parameter vs alias; aliases are top-level only |
+| R4 | The `clear_all()` change to `cleanup()` breaks thread-safety guarantees (e.g., a concurrent `send()` reads while `cleanup()` clears) | low | `clear_all()` iterates with each ProviderHistory's own lock; same as the current per-provider code. No semantic change. |
+| R5 | The RLock re-entrance causes subtle behavior differences (e.g., a method called inside `with history.lock:` may now see different lock state than before) | low | All call sites in `src/ai_client.py` acquire the lock OUTSIDE the inner dunder calls. The deadlock fix already validated this for `_send_deepseek`. |

+# 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)
+class ProjectMeta:
+    name:           str = ""
+    summary_only:   bool = False
+    execution_mode: str = "standard"
+
+
+@dataclass(frozen=True, slots=True)
+class ProjectOutput:
+    namespace:   str = "project"
+    output_dir:  str = ""  # REQUIRED by aggregate.run
+
+
+@dataclass(frozen=True, slots=True)
+class ProjectFiles:
+    base_dir:  str = ""  # REQUIRED by aggregate.run
+    paths:     tuple[str, ...] = ()
+
+
+@dataclass(frozen=True, slots=True)
+class ProjectScreenshots:
+    base_dir: str = "."
+    paths:    tuple[str, ...] = ()
+
+
+@dataclass(frozen=True, slots=True)
+class ProjectDiscussion:
+    roles:   tuple[str, ...] = ()
+    history: tuple[str, ...] = ()
+
+
+@dataclass(frozen=True, slots=True)
+class ProjectContext:
+    """Typed return type for project_manager.flat_config().
+    Replaces the dict[str, Any] that flat_config() currently returns.
+    """
+    project:         ProjectMeta         = field(default_factory=ProjectMeta)
+    output:          ProjectOutput       = field(default_factory=ProjectOutput)
+    files:           ProjectFiles        = field(default_factory=ProjectFiles)
+    screenshots:     ProjectScreenshots  = field(default_factory=ProjectScreenshots)
+    context_presets: Metadata            = field(default_factory=dict)  # opaque pass-through
+    discussion:      ProjectDiscussion   = field(default_factory=ProjectDiscussion)
+
+    def to_dict(self) -> Metadata:
+        """Convert back to the dict shape for backward compat with consumers
+        that use .get() / [] (aggregate.run et al)."""
+        return {
+            "project": {
+                "name": self.project.name,
+                "summary_only": self.project.summary_only,
+                "execution_mode": self.project.execution_mode,
+            },
+            "output": {
+                "namespace": self.output.namespace,
+                "output_dir": self.output.output_dir,
+            },
+            "files": {
+                "base_dir": self.files.base_dir,
+                "paths": list(self.files.paths),
+            },
+            "screenshots": {
+                "base_dir": self.screenshots.base_dir,
+                "paths": list(self.screenshots.paths),
+            },
+            "context_presets": dict(self.context_presets),
+            "discussion": {
+                "roles": list(self.discussion.roles),
+                "history": list(self.discussion.history),
+            },
+        }
+```
+
+Then `flat_config()` becomes:
+
+```python
+def flat_config(proj: Metadata, disc_name: Optional[str] = None, track_id: Optional[str] = None) -> ProjectContext:
+    disc_sec = proj.get("discussion", {})
+    if track_id:
+        history = load_track_history(track_id, proj.get("files", {}).get("base_dir", "."))
+    else:
+        name = disc_name or disc_sec.get("active", "main")
+        disc_data = disc_sec.get("discussions", {}).get(name, {})
+        history = disc_data.get("history", [])
+    return ProjectContext(
+        project=ProjectMeta(
+            name=proj.get("project", {}).get("name", ""),
+            summary_only=proj.get("project", {}).get("summary_only", False),
+            execution_mode=proj.get("project", {}).get("execution_mode", "standard"),
+        ),
+        output=ProjectOutput(
+            namespace=proj.get("output", {}).get("namespace", "project"),
+            output_dir=proj.get("output", {}).get("output_dir", ""),
+        ),
+        files=ProjectFiles(
+            base_dir=proj.get("files", {}).get("base_dir", ""),
+            paths=tuple(proj.get("files", {}).get("paths", [])),
+        ),
+        screenshots=ProjectScreenshots(
+            base_dir=proj.get("screenshots", {}).get("base_dir", "."),
+            paths=tuple(proj.get("screenshots", {}).get("paths", [])),
+        ),
+        context_presets=dict(proj.get("context_presets", {})),
+        discussion=ProjectDiscussion(
+            roles=tuple(disc_sec.get("roles", [])),
+            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 = ""

+    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):**
+
+```python
+# BEFORE:
+return [f.path if hasattr(f, 'path') else str(f) for f in self.files]
+
+# AFTER:
+return [f.path for f in self.files]
+```
+
+After Phase 3, `self.files` is GUARANTEED `List[FileItem]`. Every `hasattr(f, 'path')` check is redundant. Remove it.
+
+**SAFETY:**
+```bash
+git grep -nE "hasattr\(f, 'path'\)" -- 'src/app_controller.py' | wc -l
+# 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_RAG_CHUNK = RAGChunk()
+NIL_MMA_USAGE_STATS = MMAUsageStats()

+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)
+# (Note: this script only checks 3 files; the broader check is the grep above)
+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

+
+## §Phase 7: Eliminate `Any` and `dict[str, Any]` from internal function signatures (FR6)
+

+
+```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):

+
+# 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:

+```
+
+**SAFETY:**

+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 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
+After:  0 (all replaced with typed dataclasses)

+# Boundary Layer Audit (cruft_elimination_20260627)
+
+## 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]
+```

+**COMMIT:** `docs(audit): boundary layer audit for cruft_elimination_20260627`

+
+## §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'` |
+| `hasattr(f, 'path')` defensive checks | ~10 | `git grep -E "hasattr\(f, 'path'\)" -- 'src/*.py'` |
+| `hasattr(self, 'attr')` lazy-init checks | ~20 | `git grep -E "hasattr\(self," -- 'src/*.py'` |
+| Function signatures with `Metadata` parameter | ~30+ | `git grep -cE "def .+\(.*: Metadata" -- 'src/*.py'` |
+| Function signatures with `Any` parameter | ~15+ | `git grep -cE "def .+\(.*: Any" -- 'src/*.py'` |
+| Function signatures with `dict\[str, Any\]` parameter | ~20+ | `git grep -cE "def .+\(.*: dict\[str, Any\]" -- 'src/*.py'` |
+| `Optional[T]` return types | ~25+ | `git grep -cE "-> Optional\[" -- 'src/*.py'` |
+| `Any` return types | ~10+ | `git grep -cE "-> Any" -- 'src/*.py'` |
+| Effective codepaths | 4.014e+22 | baseline |
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|

+
+## 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)` |

+| VC13 | Boundary layer audit written | `docs/reports/boundary_layer_20260628.md` exists |
+| VC14 | The 12 per-aggregate dataclasses used at their specific paths | grep shows direct attribute access everywhere |
+
+## Why this is the FINAL track (no more followups)
+
+After this track:
+
+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.
+
+## See also
+
+- `conductor/code_styleguides/data_oriented_design.md` — the canonical DOD reference (Mike Acton, Ryan Fleury, Casey Muratori)
+- `conductor/code_styleguides/error_handling.md` — `Result[T]` + `NIL_T` convention
+- `conductor/code_styleguides/type_aliases.md` §2.5 — the per-aggregate dataclass rule

+- `conductor/tracks/type_alias_unfuck_20260626/spec.md` — the track that migrated the consumer sites (with the `isinstance` cruft this track removes)
+- `src/type_aliases.py` — the boundary type (`Metadata`) and the 12 componentized dataclasses
+- `src/models.py:533` — `FileItem` (canonical in-module dataclass)
+- `src/models.py:302` — `Ticket` (canonical in-module dataclass)
+- `src/openai_schemas.py` — `ToolCall`, `ChatMessage`, `UsageStats` (canonical provider-side dataclasses)
+- `conductor/AGENTS.md` — hard bans (NEVER use `git restore`, `git checkout --`, `git reset`, `git revert`)

+# Track Plan: Default Layout Extract + Hard Visual Verification
+
+> **For Tier-3 workers:** Steps use checkbox (`- [ ]`) syntax. Use exactly **1-space indentation** for all Python. Preserve **CRLF** line endings. No comments in source code. Atomic commits per task. No `dict[str, Any]`, no `Optional[T]` returns (use `Result[T]` + `NIL_T`). Read `src/gui_2.py:1481-1540` (tier-2 version) for the install helper pattern reference; read `src/theme_models.py:181-225` for the layouts loader pattern reference; read `src/paths.py:60-83,150,209-216,295` for the themes → layouts mirror.
+
+**Goal:** Extract tier-2's GOOD default-layout work into master AND build a hard 4-layer visual verification infrastructure that catches "panels don't render" regressions every time.
+
+**Architecture:** Hybrid extraction (C per spec §FR1): port `layouts/default.ini` + `src/layouts.py` + `tests/test_layout_reorganization.py` fresh (clean history for new modules); cherry-pick `c2155593` (orphan end_child) + `3b966288` (reset_layout cleanup); add new `_install_default_layout_*` helpers + `App._post_init` + `App.run` wiring. Build 4 verification layers: per-panel render sentinel (Layer 1), Win32 PrintWindow pixel baseline (Layer 2), forced test viewport+theme env vars (Layer 3), cannot-skip gates (Layer 4: standalone CLI + CI integration + tag requirement + tracks.md schema).
+
+**Tech Stack:** Python 3.11+, `imgui-bundle` (HelloImGui), `pywin32` (PrintWindow), `Pillow` (PNG), `numpy` (pixel diff), `pytest` + `live_gui` fixture. Adds `scripts/check_visual_baseline.py` (new audit-style script).
+
+---
+
+## Phase 1: Asset Foundation (layouts/ + src/layouts.py + get_layouts_dir)
+
+Focus: Port the foundational assets from tier-2 to master with clean history.
+
+- [ ] **Task 1.1: RED test for `src/layouts.py:load_layouts_from_dir`**
+  - WHERE: New file `tests/test_layouts.py`
+  - WHAT: Write 3 tests:
+    1. `test_load_layouts_from_dir_empty` — pass a non-existent path → returns `{}`
+    2. `test_load_layouts_from_dir_single_file` — create tmp dir with one `.ini` file → returns 1-entry dict keyed by stem
+    3. `test_load_layouts_from_dir_skips_non_ini` — tmp dir with `.ini` + `.txt` → returns only the `.ini`
+  - HOW: Use `tmp_path` fixture (already redirected under `tests/artifacts/_pytest_tmp` per `pyproject.toml:addopts`). Import `from src.layouts import load_layouts_from_dir`.
+  - SAFETY: Use `tmp_path`, not hardcoded paths. 1-space indentation. Type hints required.
+  - RUN: `uv run pytest tests/test_layouts.py -v` — Expected: `ModuleNotFoundError: No module named 'src.layouts'`.
+  - COMMIT: `test(layouts): RED phase tests for load_layouts_from_dir`
+
+- [ ] **Task 1.2: Create `src/layouts.py`**
+  - WHERE: New file `src/layouts.py` (87 lines, ported fresh from tier-2's `C:\projects\manual_slop_tier2\src\layouts.py`)
+  - WHAT: Define `LayoutFile` dataclass + `load_layouts_from_file()` + `load_layouts_from_dir()` + `load_layouts_from_disk()` + `_LAYOUTS_CACHE: dict[str, LayoutFile]`
+  - HOW: Read tier-2 file; copy verbatim EXCEPT: strip the "TODO(Ed)" comment (NFR3); keep the `Result` + `ErrorInfo` drain pattern from tier-2 verbatim; keep `_LAYOUTS_CACHE` module-level
+  - SAFETY: 1-space indentation. CRLF. `@dataclass(frozen=True, slots=True)`. Type hints on all params + returns.
+  - RUN: `uv run pytest tests/test_layouts.py -v` — Expected: 3 PASS.
+  - COMMIT: `feat(layouts): introduce src/layouts.py + LayoutFile dataclass`
+
+- [ ] **Task 1.3: RED test for `src/paths.py:get_global_layouts_path`**
+  - WHERE: New file `tests/test_paths_layouts.py`
+  - WHAT: Write 4 tests:
+    1. `test_get_global_layouts_path_default` — `initialize_paths()` called, `get_global_layouts_path()` returns `<root_dir>/layouts`
+    2. `test_get_global_layouts_path_env_override` — `SLOP_GLOBAL_LAYOUTS` env var set → returns that path
+    3. `test_layouts_in_path_info_dict` — `paths.path_info()` dict has `'layouts': info(...)` entry
+    4. `test_layouts_field_in_app_paths` — `_AppPaths().layouts` is a `Path`
+  - HOW: Import `from src.paths import get_global_layouts_path, initialize_paths, _cfg`. Use `monkeypatch.setenv("SLOP_GLOBAL_LAYOUTS", str(tmp_path / "custom"))`.
+  - SAFETY: Call `initialize_paths()` once per test (use fixture). 1-space indentation.
+  - RUN: `uv run pytest tests/test_paths_layouts.py -v` — Expected: `AttributeError: module 'src.paths' has no attribute 'get_global_layouts_path'`.
+  - COMMIT: `test(paths): RED phase tests for get_global_layouts_path + SLOP_GLOBAL_LAYOUTS`
+
+- [ ] **Task 1.4: Add `get_global_layouts_path()` to `src/paths.py`**
+  - WHERE: `src/paths.py` — 4 sites: line 60 `_AppPaths` dataclass (add `layouts: Path`), line 83 `_PATHS_DEFAULTS` (add `layouts = root_dir / "layouts"`), line 150 `initialize_paths._resolve_path` chain (add `SLOP_GLOBAL_LAYOUTS` env override), line 295 `path_info()` (add `'layouts': info(cfg.layouts)`), line 209-216 (add `get_global_layouts_path()` mirror of `get_global_themes_path()`)
+  - WHAT: Mirror the themes pattern exactly. New code follows the existing 1-space indentation + CRLF.
+  - HOW: Read `src/paths.py:60` → insert `layouts: Path` after `themes: Path`. Read `src/paths.py:83` → insert `themes = root_dir / "layouts"` after `themes = root_dir / "themes"`. Read `src/paths.py:150` → add `themes = _resolve_path("SLOP_GLOBAL_LAYOUTS", "layouts", root_dir / "layouts", config_path)` to the resolver chain. Read `src/paths.py:209-216` → copy `get_global_themes_path()` verbatim and rename. Read `src/paths.py:295` → insert `'layouts': info(cfg.layouts)` after `'themes': info(cfg.themes)`.
+  - SAFETY: Match existing 1-space indent. CRLF. No comments in source. Update `_resolve_path` keyword args to match the same shape as the themes line.
+  - RUN: `uv run pytest tests/test_paths_layouts.py -v` — Expected: 4 PASS.
+  - COMMIT: `feat(paths): add get_global_layouts_path() + SLOP_GLOBAL_LAYOUTS env override (mirror of themes)`
+
+- [ ] **Task 1.5: RED test for bundled INI file**
+  - WHERE: New file `tests/test_layouts_bundled.py`
+  - WHAT: Write 4 tests:
+    1. `test_layouts_default_ini_exists` — `Path("layouts/default.ini").exists()` is True
+    2. `test_layouts_default_ini_size` — file size > 1000 bytes
+    3. `test_layouts_default_ini_has_docking` — content contains `[Docking][Data]`
+    4. `test_layouts_default_ini_has_8_windows` — content has 8 `[Window][X]` entries
+  - HOW: Use `Path.cwd() / "layouts" / "default.ini"`. Use `len(re.findall(r"^\[Window\]\[", content))` for window count.
+  - SAFETY: 1-space indent. CRLF. Read with `encoding="utf-8"`.
+  - RUN: `uv run pytest tests/test_layouts_bundled.py -v` — Expected: `FileNotFoundError: layouts/default.ini`.
+  - COMMIT: `test(layouts): RED phase tests for bundled default.ini structure`
+
+- [ ] **Task 1.6: Port `layouts/default.ini` to master**
+  - WHERE: New file `layouts/default.ini` at repo root
+  - WHAT: Copy verbatim from tier-2's `C:\projects\manual_slop_tier2\layouts\default.ini` (2971 bytes, 101 lines). Strip the `;;;` documentation comments (NFR3: comments live in docs). Strip the `;;;<<<SplitIds>>>;;;` block at line 100-101 (HelloImGui adds that on save; not needed in the bundle).
+  - HOW: Read tier-2 file → write fresh to `layouts/default.ini`. Keep all `[Window][X]` entries (8 of them), `[Docking][Data]` block with `DockSpace ID=0xAFC85805`, `[Layout]`, `[StatusBar]`, `[Theme]` sections.
+  - SAFETY: CRLF. No `;;;` lines. Final file should be ~30-40 lines.
+  - RUN: `uv run pytest tests/test_layouts_bundled.py -v` — Expected: 4 PASS.
+  - COMMIT: `feat(layouts): bundle layouts/default.ini with 8 [Window] entries + [Docking] hierarchy`
+
+---
+
+## Phase 2: Install Helpers (RED-GREEN for the 3 helpers)
+

+- [ ] **Task 4.1: Cherry-pick orphan-end-child fix**
+  - WHERE: `src/gui_2.py:6990` — delete the line `imgui.end_child()` inside the `except (TypeError, AttributeError):` block in `render_tier_stream_panel`.
+  - WHAT: Apply tier-2's `c2155593` 1-line deletion. The orphan `end_child()` at line 6990 fires with no matching `begin_child()` when the try block raises (e.g. `len(None)`).
+  - HOW: Read `src/gui_2.py:6984-6991` → delete line 6990 (the `imgui.end_child()` inside except). Keep line 6988 (the correct one inside try). Keep `pass` on line 6991.

+  - WHAT: Apply tier-2's `3b966288`. The `reset_layout` command should not reference test fixtures in production code.
+  - HOW: Read `src/commands.py:365-380` → identify the line that hardcodes `tests/artifacts/manualslop_layout_default.ini` → delete it. If the surrounding logic needs adjustment (e.g. fallback to a different path), update the fallback.
+  - SAFETY: 1-space indent. CRLF. The behavior of `reset_layout` should be preserved — it still resets the layout, just from a different source path.

+## Phase 5: Layer 1 Verification — Per-Panel Render Sentinel
+
+Focus: The "panels actually render" test that catches the original bug.
+
+- [ ] **Task 5.1: RED test for per-panel render size check**
+  - WHERE: New file `tests/test_panels_visible_after_install.py`
+  - WHAT: Write 3 tests:
+    1. `test_panels_visible_after_install` — use `live_gui` fixture, wait for first frame, iterate `app.show_windows` for entries where `value == True`, assert each has nonzero render size via `imgui.find_window_viewport(name).size.x > 0`
+    2. `test_panel_invisible_when_show_windows_false` — same loop, but verify panels with `value == False` are NOT in `find_window_viewport` results
+    3. `test_panel_render_size_is_correct_window` — assert `find_window_viewport("AI Settings").size.x > 100 AND .size.y > 50` (sanity: visible panels have meaningful size, not 0)
+  - HOW: Use `live_gui` fixture. Poll for first frame via `client.wait_for_event` (not `time.sleep`). Use `imgui.find_window_viewport(name)` API.
+  - SAFETY: Poll-loop, not `time.sleep`. 1-space indent. CRLF. Skip test on non-Windows (`@pytest.mark.skipif(sys.platform != "win32")`).
+  - RUN: `uv run pytest tests/test_panels_visible_after_install.py -v` — Expected: PASS on first try IF install infrastructure works (since Phase 1-3 is done by now). The value of this test is regression detection, not initial GREEN.
+  - COMMIT: `test(visual): Layer 1 per-panel render sentinel (catches empty-panels regression)`
+
+- [ ] **Task 5.2: Verify sentinel catches the regression (negative test mode)**
+  - WHERE: Append to `tests/test_panels_visible_after_install.py`
+  - WHAT: Write `test_sentinel_catches_empty_panels` — use `live_gui` fixture, BUT monkey-patch `_install_default_layout_pre_run_result` to return `Result(data=False)` (skip install). Also, pre-create cwd/manualslop_layout.ini with content that omits all `[Window][X]` entries (just an empty INI). Assert the test FAILS.
+  - HOW: Use `monkeypatch.setattr`. The sentinel should detect that 8 default-visible panels all have zero render size.
+  - SAFETY: This test verifies the sentinel's REGRESSION CATCH ability. It should NOT pass — its job is to confirm the sentinel works.
+  - RUN: `uv run pytest tests/test_panels_visible_after_install.py::test_sentinel_catches_empty_panels -v` — Expected: FAIL with assertion error listing 8 panels with zero render size.
+  - COMMIT: `test(visual): RED negative test — sentinel catches empty-panels regression`
+
+- [ ] **Task 5.3: Verify sentinel catches the original bug (mock the import failure)**
+  - WHERE: Append to `tests/test_panels_visible_after_install.py`
+  - WHAT: Write `test_sentinel_catches_render_main_interface_no_op` — use `live_gui` fixture, monkey-patch `src.gui_2.render_main_interface` to be a no-op (`lambda app: None`). Assert the sentinel FAILS (panels don't render).
+  - HOW: This simulates the original tier-2 bug: `render_main_interface` is a no-op due to ModuleNotFoundError.
+  - SAFETY: Use `monkeypatch.setattr` to swap the function reference at module level.
+  - RUN: `uv run pytest tests/test_panels_visible_after_install.py::test_sentinel_catches_render_main_interface_no_op -v` — Expected: FAIL with assertion error listing 8 panels with zero render size.

+    2. `test_capture_returns_png_with_correct_dimensions` — assert PNG dimensions match the forced viewport (1680x1050 from F6.1 env var)
+    3. `test_capture_handles_missing_hwnd` — simulate window-not-found → return `Result(data=None, errors=[ErrorInfo])`
+    4. `test_capture_does_not_crash_on_zero_size` — simulate hwnd with zero-size window → return `Result(data=None, errors=[ErrorInfo])` (no crash)
+  - HOW: Import `_capture_gui_window_png` from `src.gui_2`. Use `live_gui` fixture with `MANUAL_SLOP_TEST_VIEWPORT=1680x1050` + `MANUAL_SLOP_TEST_THEME=dark` env vars.

Find imgui window via `win32gui.FindWindow(None, "manual slop")`; allocate DC + bitmap; call `win32gui.PrintWindow(hwnd, hdc, win32con.PW_RENDERFULLCONTENT)`; convert to PNG via `Pillow.Image.frombuffer(...)`; save to given `Path`. Returns `Result[Path]`.
+  - HOW: Import `win32gui`, `win32con`, `win32ui` from `pywin32`. Import `PIL.Image`. The function signature: `_capture_gui_window_png(out_path: Path) -> Result[Path]`.
+  - SAFETY: 1-space indent. CRLF. No comments. Wrap each Win32 call in try/except returning `ErrorInfo`. Use `win32gui.DestroyWindow(hwnd)` after capture (cleanup).

+    2. `test_pixel_diff_above_threshold_on_corrupt_ini` — corrupt the INI (delete `[Docking][Data]` line) + capture → assert diff > 5% (catches regression)
+    3. `test_pixel_diff_threshold_configurable` — pass `--threshold 0.05` → assert behavior matches
+  - HOW: Use `_compute_pixel_diff(baseline_path, current_path) -> float`. The function: load both via `Pillow.Image.open()`, convert to RGB, compute `numpy.abs(np.array(a) - np.array(b)).mean() / 255.0`.

+## Phase 8: Layer 4 Verification — Cannot-Skip Gates
+
+Focus: Make the verification infrastructure impossible to ignore.
+
+- [ ] **Task 8.1: Create `scripts/check_visual_baseline.py`**
+  - WHERE: New file `scripts/check_visual_baseline.py`
+  - WHAT: Standalone CLI script that compares two PNGs and exits 1 on diff > threshold.
+  - HOW: Args: `--baseline <path>` (default: `tests/artifacts/visual_baseline_default.png`), `--current <path>` (required), `--threshold <float>` (default: 0.01). Uses `Pillow` + `numpy` for diff. Returns exit code 0 if diff ≤ threshold, exit code 1 otherwise. Print diff percentage to stdout. Use the same `_compute_pixel_diff` logic from Task 6.5.
+  - SAFETY: 1-space indent. CRLF. Use `argparse`. Handle missing files gracefully (exit 1 + error message).
+  - RUN: `uv run python scripts/check_visual_baseline.py --help` — Expected: usage message. `uv run python scripts/check_visual_baseline.py --current tests/artifacts/visual_baseline_default.png --baseline tests/artifacts/visual_baseline_default.png` — Expected: `diff: 0.0000 PASS`.
+  - COMMIT: `feat(visual): add scripts/check_visual_baseline.py (Layer 4 standalone CI gate)`

+- [ ] **Task 8.2: Wire `check_visual_baseline.py` into `scripts/run_tests_batched.py`**
+  - WHERE: `scripts/run_tests_batched.py` — add a new tier (or extend an existing one) that runs `tests/test_visual_baseline_default.py` + `tests/test_panels_visible_after_install.py` + `scripts/check_visual_baseline.py`.
+  - WHAT: Add a tier (e.g. `tier_visual`) to the batched runner config. The tier runs after `tier3` and before the smoke tier.
+  - HOW: Read `scripts/run_tests_batched.py` config → add `tier_visual` → list the 3 commands.
+  - SAFETY: 1-space indent. CRLF. Don't break existing tiers.
+  - RUN: `uv run python scripts/run_tests_batched.py --tier visual` — Expected: 7 tests pass (4 + 3 from Phase 5-6).
+  - COMMIT: `chore(tests): wire Layer 1+2 visual tests into scripts/run_tests_batched.py`
+
+- [ ] **Task 8.3: Write `docs/guide_visual_verification.md`**
+  - WHERE: New file `docs/guide_visual_verification.md`
+  - WHAT: 200-300 line guide documenting:
+    - The 4 layers (per-panel sentinel, pixel baseline, forced viewport/theme, cannot-skip gates)
+    - How to add a new visual baseline
+    - How to update an existing baseline (after a deliberate UI change)
+    - The env-var protocol (`MANUAL_SLOP_TEST_VIEWPORT`, `MANUAL_SLOP_TEST_THEME`)
+    - The `VERIFIED-<YYYYMMDD>` tag protocol
+    - When to use imgui_test_engine vs PrintWindow (the trade-offs)

+  - WHAT: Add a new section documenting the `VERIFIED-<YYYYMMDD>` tag requirement for tracks that touch `src/gui_2.py`. Tracks that ship without the tag are NOT marked `[x]`.
+  - HOW: Read `conductor/tracks.md` → find the schema → add the new gate.
+  - SAFETY: Markdown formatting consistent. Cross-reference `docs/guide_visual_verification.md`.
+  - RUN: N/A (docs file).
+  - COMMIT: `docs(tracks): add VERIFIED-<date> tag requirement for tracks touching src/gui_2.py`

+- [ ] **Task 9.1: Write `tests/test_visual_baseline_catches_corrupt_ini.py`**
+  - WHERE: New file `tests/test_visual_baseline_catches_corrupt_ini.py`
+  - WHAT: Write 1 test that uses `live_gui` fixture; AFTER install fires, manually delete the `[Docking][Data]` line from cwd/manualslop_layout.ini; re-launch + capture; assert pixel diff > 5%.
+  - HOW: Spawn app → wait for first frame → corrupt INI → quit → re-launch → wait for first frame → capture screenshot → compare to baseline.
+  - SAFETY: 1-space indent. CRLF. Use `kill_process_tree` fixture for cleanup. Skip on non-Windows.
+  - RUN: `uv run pytest tests/test_visual_baseline_catches_corrupt_ini.py -v` — Expected: PASS (the diff should be > 5% because panels don't render visibly).
+  - COMMIT: `test(visual): negative test — corrupted INI catches the regression (FR8)`
+
+- [ ] **Task 9.2: Run full test batch**
+  - WHERE: All test files added in Phase 1-9
+  - WHAT: Run `scripts/run_tests_batched.py` end-to-end. Verify all tiers PASS.
+  - HOW: `uv run python scripts/run_tests_batched.py` — runs the full batch (not just `tier_visual`).
+  - SAFETY: If any tier fails, STOP. Report to user. Do NOT mark track complete.
+  - RUN: Expected: all 11 tiers PASS. If a tier fails, debug per `conductor/workflow.md` "Deduction Loop" rule (max 2 runs).
+  - COMMIT: N/A (verification only).
+
+- [ ] **Task 9.3: Manual visual verification gate**
+  - WHERE: User's machine
+  - WHAT: User runs `uv run sloppy.py` from master. User confirms panels render visibly (Project Settings, Files & Media, AI Settings, Operations Hub, Theme on left; Discussion Hub, Log Management, Diagnostics on right).
+  - HOW: User reports back. If panels DO render visibly → proceed. If panels DON'T render → STOP, debug, report.
+  - SAFETY: N/A (manual gate).
+  - COMMIT: N/A (manual verification only).

+- [ ] **Task 9.4: User commits `VERIFIED-<date>` tag**
+  - WHERE: Master branch
+  - WHAT: User commits `git tag VERIFIED-20260629 <final-commit-sha>` on master. Documents the visual verification.
+  - HOW: `git tag VERIFIED-20260629 <sha>`. Add to track completion checklist.
+  - SAFETY: HARD GATE. Without this tag, the track is NOT marked complete in `conductor/tracks.md`.
+  - COMMIT: N/A (tag, not commit). But attach a git note to the final commit: `git notes add -m "VISUALLY VERIFIED: panels render correctly via uv run sloppy.py from master"`.

+  - WHAT: Update the row.
+  - HOW: Read `conductor/tracks.md` → find the row → update.

+# Track Specification: Default Layout Extract + Hard Visual Verification
+
+## Overview
+
+Extract tier-2's GOOD work on the default layout setup (the `layouts/` directory, the install-on-empty-INI helpers, the pre-run install timing fix, and the orphan-end-child cleanup) into `master`, and replace the previous tier-2 "fake" verification (INI content assertions only) with a HARD 4-layer visual verification protocol that catches the "panels don't render" regression every time it occurs.
+
+## Current State Audit (as of commit `466d2656` on master)
+
+### Branch State Warning
+
+The main working tree at `C:\projects\manual_slop` is currently on branch `tier2/post_module_taxonomy_de_cruft_20260627` (NOT master). This track targets `master`. All line numbers below are from `master` (verified via `git show master:src/gui_2.py`). The cruft-elimination tracks (`module_taxonomy_refactor_20260627` + `post_module_taxonomy_de_cruft_20260627`) are NOT merged to master — they live on tier-2 branches only. This track does NOT depend on those cruft tracks; it depends only on `cruft_elimination_20260627` (which IS merged to master) + the themes infrastructure in `src/paths.py` (which is on master). A separate master worktree exists at `C:\projects\manual_slop_master` for editing on the master branch without disturbing the cruft-branch working tree.
+
+### Already Implemented on Master
+
+- `src/paths.py:60,83,150,209-216` — themes infrastructure (the pattern to mirror for layouts): `themes: Path` field in `_AppPaths`, default `root_dir / "themes"`, env override `SLOP_GLOBAL_THEMES`, getters `get_global_themes_path()` and `get_project_themes_path(project_root)`, plus the path info dict entry at line 295.
+- `src/theme_2.py:340-346` + `src/theme_models.py:181-225` — themes loader pair (the pattern to mirror for layouts): `load_themes_from_disk()` calls `get_global_themes_path()` then `load_themes_from_dir(path, scope)`; the latter iterates children, parses, builds typed `@dataclass(frozen=True, slots=True)` records, drains errors via `Result + ErrorInfo`.
+- `src/gui_2.py:1776` — `from src.command_palette import render_palette_modal`. **MASTER WORKS**: `src/command_palette.py` EXISTS (165 lines, has `Command`, `ScoredCommand`, `CommandRegistry`, `render_palette_modal`). Tier-2 broke because they deleted `src/command_palette.py` in `module_taxonomy_refactor_20260627` (commit `3dd153f7`, NOT merged to master).
+- `src/gui_2.py:580-611` — `_diag_layout_state` (one-shot startup diagnostic that logs `show_windows` count + INI file size + stale window name warnings). Used as the install verification hook.
+- `src/gui_2.py:619-703` — `App.run`. Calls `_run_immapp_result(self)` at line 691. HelloImGui reads `runner_params.ini_filename` ("manualslop_layout.ini") from cwd at load_user_pref time, BEFORE `callbacks.post_init` fires.
+- `src/gui_2.py:566-578` — `App._post_init`. Calls `_post_init_callback_result` and `_diag_layout_state`. Fires AFTER HelloImGui has loaded the INI from disk.
+- `src/gui_2.py:1449-1470` — `_post_init_callback_result` (drain-aware wrapper for `App._post_init`). The pattern Tier-2's `_install_default_layout_if_empty_result` and `_install_default_layout_pre_run_result` follow.
+- `src/gui_2.py:1658-1660` — orphan-end-child bug was refactored OUT of `_tier_stream_scroll_sync_result` (the helper that was previously buggy). The orphan at line 6990 (in `render_tier_stream_panel`'s except block) STILL exists on master.
+- `src/gui_2.py:6981-6991` — `render_tier_stream_panel` has the latent orphan-end-child bug: `try: ... imgui.end_child()` at line 6988; `except (TypeError, AttributeError): imgui.end_child()` at line 6990. When the try block raises (e.g. `len(None)`), the second `end_child()` fires with no matching `begin_child()` and ImGui emits "In window 'MainDockSpace': Missing End()". Currently latent because `len(content)` rarely raises.
+- `tests/conftest.py:700-712` — pre-baked `tests/artifacts/manualslop_layout_default.ini` shipped to fresh test workspaces. Hardcoded path (cwd-relative test fixture) — violates "production code uses cwd-relative paths only" rule.
+- `src/commands.py:248-275` — `reset_layout` command with hardcoded `tests/artifacts/live_gui_workspace/manualslop_layout.ini` path at line 268 (dead code in production; references a test-fixture path that doesn't exist in production cwd).
+- `conductor/tracks/default_layout_install_20260629/` — Tier-1 track scaffolding from this session. States the user's intent.
+- `conductor/tracks/default_layout_install_followup_20260629/` — Tier-1 followup track that supersedes Tier-2's wrong-theory `e9654518` strip-docking fix.
+
+### Already Implemented on Tier-2 Branch (NOT on master)
+
+- `layouts/default.ini` (2971 bytes, 101 lines) — bundled INI with full `[Docking][Data]` hierarchy (DockSpace ID=0xAFC85805 + DockNode 0x00000001 + DockNode 0x00000002 + 8 per-window `DockId=...` entries). Comments document the runtime-generated ID semantics.
+- `src/layouts.py` (3178 bytes, 88 lines) — `LayoutFile` dataclass + `load_layouts_from_file()` + `load_layouts_from_dir()` + `load_layouts_from_disk()` (mirrors `src/theme_models.py:181-225` shape exactly).
+- `src/gui_2.py:1481-1540` — `_install_default_layout_if_empty` + `_install_default_layout_if_empty_result` (drain-aware wrapper). The function: reads dst INI; if empty (<1000 bytes OR no `[Window][`), reads bundled src INI, writes to dst, calls `imgui.load_ini_settings_from_memory(src_text)` to apply to live session.
+- `src/gui_2.py:1543-1590` — `_install_default_layout_pre_run_result`. Same logic but disk-only (no `load_ini_settings_from_memory`) because imgui is not yet initialized before `immapp.run()`. This is the timing fix Tier-2 added after the post-init version was too late for the first session.
+- `src/gui_2.py:701-706` — `App.run` wiring: calls `_install_default_layout_pre_run_result(self)` BEFORE `_run_immapp_result(self)`. Drains errors to `_startup_timeline_errors`.
+- `src/gui_2.py:579-582` — `App._post_init` wiring: calls `_install_default_layout_if_empty_result(self, src_layout_path, dst_layout_path)`. Drains errors.
+- `tests/test_layout_reorganization.py` (66 lines) — RED tests for the install-on-empty-INI behavior (per tier-2 claim "17/17 PASSED"; tests check INI content, not visible panels).
+
+### Gaps to Fill (This Track's Scope)
+
+| Gap | Severity | Layer |
+|---|---|---|
+| `layouts/` directory + `layouts/default.ini` + `src/layouts.py` missing on master | High | (the assets themselves) |
+| `_install_default_layout_if_empty` + `_install_default_layout_pre_run_result` helpers missing on master | High | (the install behavior) |
+| `App._post_init` and `App.run` wiring missing on master | High | (the install triggers) |
+| `get_layouts_dir()` in `src/paths.py` missing on master | High | (the path resolver; mirrors themes) |
+| `reset_layout` command still references dead `tests/artifacts/manualslop_layout_default.ini` path | Medium | cleanup |
+| Orphan `imgui.end_child()` at `src/gui_2.py:6990` (latent; fires when tier-stream try-block raises) | Medium | cleanup |
+| **No hard verification that panels actually render visually** | Critical | verification infrastructure |
+
+### Tier-2's "Bullshit" We're NOT Extracting
+
+| Commit | Why Skip |
+|---|---|
+| `e9654518` "strip stale dockspace IDs" | Wrong theory (superseded by `2afb0126`; that one we DO extract) |
+| `13ad9d3e` "idk" | Meaningless commit message; bulk-edited `manualslop_layout.ini` |
+| `28527851` "artifacts" | Meaningless commit; bulk-edited artifacts |
+| `9437af6c` "archive 27 diagnostic scripts" | 27 throwaway scripts not needed in master |
+| `4acf8b15`, `b80e5afb`, `c42a7599`, `cf5244b1`, `b1632f46`, `06476c56`, `519e1340`, `cf6a2e20`, `4bf5ecd6`, `5e53d477`, `d4116f19`, `7d5a5492`, `15cd1262`, `23566da8` | Tier-2 internal track-marking commits; we write our own |
+| `71028dad` "drop stale `from src.command_palette import`" | Tier-2 specific: master has `src/command_palette.py` so the import WORKS on master. The stale import bug only exists on tier-2 because they deleted the module. **We do not cherry-pick this.** |
+
+### Why the User Wants This Track
+
+The tier-2 track was marked "SHIPPED" based on:
+- 17/17 install/layout tests PASS (which only check INI content, not visible panels)
+- Manual launch produces a 3072-byte INI with correct structure (content check, not visible check)
+- "the imgui core loader rejected the literal IDs from the bundled INI because the runtime IDs didn't match" — claim contradicted by post-fix INI matching runtime IDs
+
+**None of those commits empirically verified visible panels after install.** The user wants this regression to never happen again. The previous tier-2 "fake" verification must be replaced by a HARD one.
+
+## Goals
+
+**G1.** Master has `layouts/default.ini` + `src/layouts.py` + `get_layouts_dir()` so the app boots with a non-empty INI on first launch.
+
+**G2.** Master has `_install_default_layout_if_empty` + `_install_default_layout_pre_run_result` wired into `App._post_init` + `App.run` so empty-INI detection + install-on-empty works at both phases (live session + first session).
+
+**G3.** Master has `reset_layout` cleaned up to remove the dead test-fixture path (no more `tests/artifacts/...` in production code).
+
+**G4.** Master has the orphan `imgui.end_child()` at `src/gui_2.py:6990` removed.
+
+**G5.** Master has a HARD 4-layer visual verification infrastructure:
+- **Layer 1 (Per-Panel Sentinel)**: a `tests/test_panels_visible_after_install.py` test that asserts every `show_windows[k]==True` panel has nonzero render size after first frame.
+- **Layer 2 (Win32 PrintWindow Pixel Baseline)**: a `tests/test_visual_baseline_default.py` test that captures the running GUI window's pixels via Win32 `PrintWindow` API and compares against `tests/artifacts/visual_baseline_default.png` with <1% pixel-diff tolerance. Catches ALL visual regressions (empty workspace, wrong INI, missing panels, overlap, theme corruption).
+- **Layer 3 (Forced Test Viewport + Theme)**: `MANUAL_SLOP_TEST_VIEWPORT=1680x1050` + `MANUAL_SLOP_TEST_THEME=dark` env vars honored at startup. Forces fixed viewport + known theme so the baseline PNG is deterministic.
+- **Layer 4 (Cannot-Skip Gates)**: `scripts/check_visual_baseline.py` (exits 1 if pixel diff > 1%); wire into `scripts/run_tests_batched.py`; require `git tag VERIFIED-<YYYYMMDD>` on the merge commit; `conductor/tracks.md` schema update so `[x]`-completion requires the tag.
+
+**G6.** A regression test demonstrates that the verification infrastructure catches the original "panels don't render" bug (negative test: corrupt the installed INI, verify the sentinel + pixel baseline both fail).
+

+- F1.1. Port `layouts/default.ini` fresh from tier-2's `C:\projects\manual_slop_tier2\layouts\default.ini` (2971 bytes, 101 lines) to `layouts/default.ini` at master repo root. Rationale: clean history for new asset; user-facing content.
+- F1.2. Port `src/layouts.py` fresh from tier-2's `C:\projects\manual_slop_tier2\src\layouts.py` (88 lines). Mirrors `src/theme_models.py:181-225` shape. Rationale: clean history for new module; matches `src/theme_2.py` + `src/theme_models.py` pair.
+- F1.3. Add `get_layouts_dir()` to `src/paths.py` mirroring `get_global_themes_path()` at line 209. Add `layouts: Path` field to `_AppPaths` (line 60), default `root_dir / "layouts"` (line 83), env override `SLOP_GLOBAL_LAYOUTS` (line 150), path info dict entry (line 295). User explicitly authorized "make a layouts directory similar to the themes directory" in the prior session.
+- F1.4. Port `tests/test_layout_reorganization.py` fresh from tier-2 (66 lines). Rationale: tests for the install helpers.
+
+### FR2. Install Helpers + Wiring
+- F2.1. Add `_install_default_layout_if_empty(src_ini: Path, dst_ini: Path) -> Result[bool]` to `src/gui_2.py` (per tier-2 line 1481). Reads dst; if empty (<1000 bytes OR no `[Window][`), copies src→dst and calls `imgui.load_ini_settings_from_memory(src_text)` to apply to live session.
+- F2.2. Add `_install_default_layout_if_empty_result(app: "App", src: Path, dst: Path) -> Result[bool]` (per tier-2 line 1530). Drain-aware passthrough wrapper.
+- F2.3. Add `_install_default_layout_pre_run_result(app: "App") -> Result[bool]` (per tier-2 line 1543). Disk-only install (no `load_ini_settings_from_memory`); imgui isn't initialized yet.
+- F2.4. Wire `_install_default_layout_if_empty_result` into `App._post_init` (line 566-578). Source path: `get_layouts_dir() / "default.ini"`. Dst path: `Path.cwd() / "manualslop_layout.ini"`. Drain errors to `_startup_timeline_errors`.
+- F2.5. Wire `_install_default_layout_pre_run_result` into `App.run` (line 619-703, insert before line 691 `_run_immapp_result(self)`). Drain errors to `_startup_timeline_errors`.
+
+### FR3. Surgical Cherry-Picks
+- F3.1. Cherry-pick `c2155593 fix(gui): remove orphan imgui.end_child() in render_tier_stream_panel except handler`. Apply the 1-line deletion to `src/gui_2.py:6990`. Tier-2 verified this fixes an imgui "Missing End()" error in MainDockSpace when the tier-stream try-block raises. Latent on master but real.
+- F3.2. Cherry-pick `3b966288 chore(commands): remove dead test-fixture path from reset_layout`. Apply the deletion to `src/commands.py:268` (the `tests/artifacts/live_gui_workspace/manualslop_layout.ini` hardcoded path in the `layout_paths` list).
+
+### FR4. Layer 1 — Per-Panel Render Sentinel
+- F4.1. New test file `tests/test_panels_visible_after_install.py`. Imports `live_gui` fixture from `tests/conftest.py`.
+- F4.2. RED: assert that for each `show_windows[k]==True` entry, after first frame, `imgui.find_window_viewport(k).size.x > 0 AND .size.y > 0`. Test should fail on the current baseline (we don't have the install helpers yet) — confirms sentinel catches the regression.
+- F4.3. GREEN: with the install helpers in place (FR2), test passes.
+- F4.4. Test must use poll-loop (not `time.sleep`) per `conductor/workflow.md` "Async Setters Need Poll-For-State".
+
+### FR5. Layer 2 — Win32 PrintWindow Pixel Baseline
+- F5.1. New test file `tests/test_visual_baseline_default.py`. Imports `live_gui` fixture.
+- F5.2. Capture: import `win32gui` from `pywin32`; find imgui window HWND via `win32gui.FindWindow(None, "manual slop")`; allocate DC + bitmap; call `win32gui.PrintWindow(hwnd, hdc, PW_RENDERFULLCONTENT)`; convert bitmap to PNG via `Pillow` (already a dep); save to `tests/artifacts/<test_session>_<date>.png`.
+- F5.3. Baseline: commit `tests/artifacts/visual_baseline_default.png` (the "known good" reference). Generated AFTER F5.1 + F5.2 are GREEN against the new install infrastructure.
+- F5.4. Compare: load baseline + current via `Pillow.Image.open(...)`; convert to RGB; compute pixel diff via `numpy.abs(np.array(a) - np.array(b)).mean() / 255.0`. Threshold: 0.01 (1%). Fail if > 1%.
+- F5.5. RED: with the install infrastructure removed, the test must fail. Confirms the test catches the regression.
+- F5.6. Test must poll for first frame + capture screenshot AT MOST ONCE (don't spam captures).
+
+### FR6. Layer 3 — Forced Test Viewport + Theme
+- F6.1. Add `MANUAL_SLOP_TEST_VIEWPORT=1680x1050` env var support to `App.run` (line 619). If set, override `self.runner_params.app_window_params.window_geometry.size` to the env-var value (parsed as `WxH`).
+- F6.2. Add `MANUAL_SLOP_TEST_THEME=dark` env var support to `App.run` (line 619). If set, force `self.runner_params.imgui_window_params.tweaked_theme = ImGuiTheme_.ImGuiColorsDark` (the default dark theme).
+- F6.3. RED: write `tests/test_test_mode_env_vars.py` that asserts both env vars are honored when set (via `live_gui` fixture with env vars).
+- F6.4. GREEN: implement the env-var parsing in `App.run`.
+
+### FR7. Layer 4 — Cannot-Skip Gates
+- F7.1. New file `scripts/check_visual_baseline.py`. Imports `live_gui` (no — too heavy for a CLI script). Instead, accepts `--baseline <path>` + `--current <path>` + `--threshold <float>` CLI args. Uses `Pillow.Image.open()` + `numpy.abs(...).mean()` to compute diff. Exits 1 if diff > threshold.
+- F7.2. Add `scripts/check_visual_baseline.py` to `scripts/run_tests_batched.py` tier-2 test list (or a new tier dedicated to visual regression).
+- F7.3. Document the `VERIFIED-<YYYYMMDD>` git-tag requirement in `conductor/tracks.md` schema section. Tracks that touch `src/gui_2.py` MUST carry the tag for `[x]`-completion.
+- F7.4. New doc `docs/guide_visual_verification.md` (200-300 lines). Documents the 4 layers, how to add a new visual baseline, how to update an existing baseline, the env-var protocol, the tag protocol.
+
+### FR8. Negative Test (Regression Catch Demonstration)
+- F8.1. New test file `tests/test_visual_baseline_catches_corrupt_ini.py`. Uses `live_gui` fixture; AFTER the install infrastructure has run, manually corrupt the installed INI (delete `[Docking][Data]` line). Re-launch + capture screenshot. Verify pixel diff > 5% (the corrupted INI shows empty workspace, baseline shows full panels).
+- F8.2. Negative test must run in a separate `pytest` session (not pollute `live_gui` state).
+
+## Non-Functional Requirements
+
+### NFR1. Atomic Per-Task Commits
+Every Phase task results in exactly ONE atomic commit. No batched commits. Per `AGENTS.md` "Critical Anti-Patterns" — "Do not batch commits - commit per-task for atomic rollback".
+
+### NFR2. TDD Red-First
+Every implementation task has a preceding RED test task. Per `conductor/workflow.md` "Standard Task Workflow" §4.
+
+### NFR3. No Comments in Source Code
+Per `AGENTS.md` "Critical Anti-Patterns" — "Do not add comments to source code; documentation lives in /docs".
+
+### NFR4. No Diagnostic Noise in Production
+Per `AGENTS.md` "Critical Anti-Patterns" — diag stderr goes to `tests/artifacts/*.diag.log` or `/tmp`, NOT `src/*.py`.
+
+### NFR5. 1-Space Indentation
+Per `conductor/workflow.md` "Code Style (MANDATORY - Python)" — exactly 1 space per level for ALL Python code.
+
+### NFR6. CRLF Line Endings on Windows
+Per `conductor/workflow.md` "Code Style (MANDATORY - Python)" — preserve CRLF.
+
+### NFR7. Type Hints Required
+Per `conductor/product-guidelines.md` "AI-Optimized Compact Style" — strict type hints on all parameters, return types, globals.
+
+### NFR8. No `dict[str, Any]` / `Optional[T]` in Non-Boundary Code
+Per `conductor/code_styleguides/data_oriented_design.md` §8.5 + `python.md` §17. Typed `@dataclass(frozen=True, slots=True)` + `Result[T]` + `NIL_T`.
+
+### NFR9. ImGui Defer Patterns
+Per `conductor/code_styleguides/python.md` — use `imscope` context managers over manual `imgui.begin/end` pairs (where applicable). Existing manual pairs in `src/gui_2.py` are unchanged.
+
+### NFR10. Manual Slop MCP Tools Only
+Per the system prompt — use `manual-slop_*` MCP tools, NOT native `read`/`edit`/`grep` (where the MCP equivalents are available). When MCP tools aren't available (which is the case for this Tier-1 track creation), native `read`/`edit`/`grep`/`write` are the fallback.
+
+## Architecture Reference
+
+- **`docs/guide_gui_2.md`** §"App class lifecycle" + §"_post_init + App.run" — current rendering flow; where the install helpers slot in.
+- **`docs/guide_architecture.md`** §"Thread domains, event system" — confirms main thread owns `App.run`; install helpers run on main thread (no thread-safety concerns).
+- **`docs/guide_testing.md`** §"`live_gui` fixture" + §"Puppeteer pattern" + §"Structural Testing Contract" — the live_gui fixture is the test harness for FR4-FR8.
+- **`conductor/code_styleguides/data_oriented_design.md`** §8.5 — the Python Type Promotion Mandate. Bound by NFR8.
+- **`conductor/code_styleguides/error_handling.md`** — `Result[T]` + `ErrorInfo` + `ErrorKind` usage. The install helpers return `Result[bool]` per this styleguide.
+- **`conductor/code_styleguides/type_aliases.md`** — `Metadata = TrackMetadata` etc. The new `LayoutFile` dataclass follows the typed-record pattern from this styleguide.
+- **`conductor/code_styleguides/feature_flags.md`** — "delete to turn off" (file presence) for the bundled INI. If `layouts/default.ini` is deleted, `_install_default_layout_if_empty` returns `Result(data=False)` (no install).
+- **`docs/guide_visual_verification.md`** (NEW, FR7.4) — the documentation deliverable.
+
+## Out of Scope
+
+1. **Fleury declarative view-constructs migration** (`PANELS: tuple[PanelDef, ...]`). Logged in `default_layout_install_20260629/metadata.json` `deferred_to_followup_tracks[0]`. Requires its own track.
+2. **imgui_test_engine integration** (`test_engine_integration_20260627`). Provides pixel-level diff via `ctx.capture_screenshot_window()`. Our Win32 PrintWindow approach is simpler + works without test engine. The two approaches are complementary; layering them is a future task.
+3. **Reverting tier-2's working tree state**. User's responsibility per the Inherited-Cruft rule. Tier-2's `git status` shows uncommitted `manual_slop.toml` + `manual_slop_history.toml` deletions; user must explicitly handle those.
+4. **Cross-platform pixel diff** (Linux/macOS). Win32 PrintWindow is Windows-only. The track ships Windows-only; CI on Linux/macOS would skip FR5 (marked `@pytest.mark.skipif(sys.platform != "win32")`).
+5. **Pre-baked test INI shipped from `tests/conftest.py:700-712`**. Replaced by FR5.3 baseline PNG.
+6. **`render_persona_editor_window` bug** at `src/gui_2.py:3433+` (opens + immediately closes the Persona Editor window when not embedded). Pre-existing; unrelated to panel visibility. Logged for followup.
+
+## Coordination with Pending Tracks
+
+- **`default_layout_install_20260629/`** — supersedes. Tier-1 scaffolding for this work. The plan.md tasks here replace `conductor/tracks/default_layout_install_20260629/plan.md`.
+- **`default_layout_install_followup_20260629/`** — supersedes. The followup plan assumed tier-2's `e9654518` INI strip was the right fix; this track's plan supersedes that with the hybrid extraction.
+- **`test_engine_integration_20260627`** — independent. Not blocked by, does not block this track. May consume the env-var protocol (FR6.1 + F6.2) once integrated.
+- **`panel_defs_fleury_migration_20260629`** (deferred) — future. Will consume `LayoutFile` + `get_layouts_dir()` from this track.
+
+## Verification Criteria (Track Completion Gates)
+
+- [ ] All Phase 1-9 tasks committed (atomic per-task)
+- [ ] `tests/test_panels_visible_after_install.py` passes (Layer 1 sentinel)
+- [ ] `tests/test_visual_baseline_default.py` passes (Layer 2 pixel diff < 1%)
+- [ ] `tests/test_test_mode_env_vars.py` passes (Layer 3 env vars honored)
+- [ ] `tests/test_visual_baseline_catches_corrupt_ini.py` passes (FR8 negative test)
+- [ ] `scripts/check_visual_baseline.py --help` works; `--strict` mode exits 1 on diff > 1%
+- [ ] `scripts/run_tests_batched.py` includes the visual verification tests
+- [ ] `tests/artifacts/visual_baseline_default.png` is committed to master
+- [ ] `docs/guide_visual_verification.md` is committed; cross-referenced from `docs/Readme.md`
+- [ ] `conductor/tracks.md` schema updated to require `VERIFIED-<YYYYMMDD>` tag for `[x]`-completion of tracks touching `src/gui_2.py`
+- [ ] **MANUAL GATE**: user runs `uv run sloppy.py` from master, confirms panels render visibly. User commits the `VERIFIED-<date>` tag.
+- [ ] `docs/reports/TRACK_COMPLETION_default_layout_extract_20260629.md` committed
+- [ ] Tier-2 branch status: marked for archival (user's responsibility per AGENTS.md "Inherited-Cruft")
+
+## Scope Summary (per workflow.md "Tier 1 Track Initialization Rules")
+
+- **Scope**: 9 phases, ~36 tasks
+- **Files touched**: ~12 (3 new: `src/layouts.py`, `layouts/default.ini`, `tests/artifacts/visual_baseline_default.png`, `scripts/check_visual_baseline.py`, `docs/guide_visual_verification.md`; 6 modified: `src/gui_2.py`, `src/paths.py`, `src/commands.py`, `tests/test_layout_reorganization.py`, `tests/test_panels_visible_after_install.py` (new), `tests/test_visual_baseline_default.py` (new), `tests/test_test_mode_env_vars.py` (new), `tests/test_visual_baseline_catches_corrupt_ini.py` (new), `scripts/run_tests_batched.py`, `conductor/tracks.md`, `docs/Readme.md`)
+- **Sites modified**: ~15 (in `_post_init`, `App.run`, `_install_default_layout_*`, `_diag_layout_state`, etc.)
+- **Tasks**: ~36
+
+## Risk Register
+
+- **R1** — Win32 PrintWindow may fail for the imgui-bundle HelloImGui window (HWND lookup or print flags). **Mitigation**: pre-flight check `win32gui.IsWindow(hwnd)` before capture; fall back to `BitBlt` of the screen region.
+- **R2** — Pixel baseline may be too sensitive (font hinting, GPU driver variations). **Mitigation**: tolerance is 1%; if false positives appear, raise to 2% and document.
+- **R3** — Forced viewport env var may not work on multi-monitor systems. **Mitigation**: scope the env var to test fixtures only (`tests/conftest.py` sets it before spawning).
+- **R4** — Tier-2 sandbox has uncommitted edits that may conflict when cherry-picking. **Mitigation**: cherry-pick to master directly (master is clean); tier-2 archival is user's responsibility.
+- **R5** — User-visible panel rendering depends on `_install_default_layout_pre_run_result` firing BEFORE `immapp.run`. If the user's cwd already has a valid `manualslop_layout.ini`, the install is skipped. The pixel baseline test must run with cwd-deleted `manualslop_layout.ini` to exercise the install path. **Mitigation**: `live_gui` fixture already cleans cwd before spawning.

+## Phase 1: Move default layout + create layouts/ stack (parallel to themes/)
+
+Focus: relocate `tests/artifacts/manualslop_layout_default.ini` to `layouts/default.ini` at repo root; add the parallel `src/paths.py` field, `get_layouts_dir()` accessor, and `src/layouts.py` loader module — exactly the themes pattern (`themes/` + `src/path.py:60,83,150` + `src/theme_models.py` + `src/theme_2.py`).
+
+- [x] Task 1.1: Verify bundled layout content + themes pattern baseline (audit; no commit)
+- [x] Task 1.2 [7577d7d]: `git mv` asset to new home
+  - WHERE: `tests/artifacts/manualslop_layout_default.ini` → `layouts/default.ini` (new dir at repo root, parallel to `themes/`)
+  - WHAT: `git mv tests/artifacts/manualslop_layout_default.ini layouts/default.ini`
+  - HOW: PowerShell `git mv` preserves history; verify with `git status` after
+  - SAFETY: file rename, no content change; `layouts/` is gitignored? verify — `grep -i "layouts" .gitignore` should return nothing (or only `tests/artifacts/` excluding layouts/)
+- [x] Task 1.3 [7577d7d]: Update `tests/conftest.py:709` to read from `layouts/`
+- [x] Task 1.4 [7577d7d]: Add `layouts` field to `src/paths.py` config dataclass (mirror themes line 60)
+  - WHERE: `src/paths.py:60` (`themes: Path = ...`) — add a `layouts: Path = ...` field right after
+  - WHAT: add the field declaration matching the `themes` shape exactly
+  - HOW: `manual-slop_edit_file`; 1-space indent
+  - SAFETY: additive — does not change existing fields
+- [x] Task 1.5 [7577d7d]: Resolve `layouts` default in `src/paths.py` (mirror themes line 83)
+  - WHAT: resolve the default path in the `initialize_paths`-style function
+  - HOW: `manual-slop_edit_file`; ensure the same closure/call-site shape as themes
+  - SAFETY: additive; existing themes path unchanged
+- [x] Task 1.6 [7577d7d]: Add `SLOP_GLOBAL_LAYOUTS` env + config override (mirror themes line 150)
+  - WHERE: `src/paths.py:150` — add `_resolve_path("SLOP_GLOBAL_LAYOUTS", "layouts", root_dir / "layouts", config_path)` line in the same call shape
+  - WHAT: register the env var + config-file override for `layouts`, parallel to themes
+  - HOW: `manual-slop_edit_file`; exact-string preserve the existing `_resolve_path` call for themes
+  - SAFETY: additive; new env var only
+- [x] Task 1.7 [7577d7d]: Add `get_layouts_dir()` accessor to `src/paths.py` (mirror themes accessor at ~210)
+  - WHERE: `src/paths.py:210-216` — add 2 functions (`get_layouts_dir() -> Path` + `get_layouts_project_config_path() -> Path` if themes has it) right after

+  - HOW: `manual-slop_edit_file`; preserve docstring format
+  - SAFETY: additive
+- [x] Task 1.8 [7577d7d]: Create `src/layouts.py` loader module (mirror `src/theme_models.py` + `src/theme_2.py`)
+  - WHERE: new file `src/layouts.py`
+  - WHAT: define `LayoutFile` `@dataclass(frozen=True, slots=True)` with `(name: str, raw_text: str, source_path: Path, scope: str)` fields; define `load_layouts_from_dir(path: Path, scope: str) -> dict[str, LayoutFile]` and `load_layouts_from_file(path: Path, scope: str) -> dict[str, LayoutFile]`; define `load_layouts_from_disk() -> None` that calls both with global + project paths; wrap parse errors in `Result` per `conductor/code_styleguides/error_handling.md`

+  - SAFETY: pure inspection
+- [x] Task 1.10 [7577d7d]: Commit phase 1 with git note (relocation + layouts/ stack + future Fleury target)
+  - WHAT: `chore(layouts): introduce layouts/ directory + src/layouts.py (themes pattern); relocate default layout asset`
+  - HOW: standard atomic commit per `conductor/workflow.md` §Task Workflow; attach a 3-line git note explaining: relocation from tests/artifacts; parallel to themes; src/layouts.py mirrors src/theme_models.py + src/theme_2.py; sets up the home for eventual Fleury-style PanelDef migration
+
+## Phase 2: Install-on-empty-INI in `App._post_init`
+
+Focus: ship `layouts/default.ini` to `cwd/manualslop_layout.ini` when the file is missing/empty/small, before `immapp.run(...)` reads it.
+
+- [x] Task 2.1 [35f22e4d]: Write failing test for install behavior (Tier 3 dispatching tests/test_default_layout_install.py)
+  - WHERE: new file `tests/test_default_layout_install.py`
+  - WHAT: red phase — 3 tests:
+    1. `test_default_layout_installed_when_ini_missing` — `os.remove(cwd/manualslop_layout.ini)` before launch; `subprocess.Popen(sloppy_args, cwd=temp_workspace)`; wait ≥ 5s; assert `manualslop_layout.ini` exists with `[Window][Project Settings]` entry + a non-empty `DockId=` line
+    2. `test_default_layout_installed_when_ini_empty` — write a 5-byte stub INI before launch; same assertions as (1)
+    3. `test_default_layout_NOT_installed_when_layout_present` — pre-write a custom `[Window][CustomPanel]` INI; assert the custom panel survives (no overwrite)
+  - HOW: each test spawns the app via `subprocess.Popen(["uv", "run", "python", "-u", "sloppy.py", "--enable-test-hooks"], cwd=temp_workspace, stdout=log_file, stderr=log_file, creationflags=subprocess.CREATE_NEW_PROCESS_GROUP)` (mirrors the conftest at line 792), waits 5-8s, terminates via `kill_process_tree()` (per the conftest pattern at line 853), then asserts on the saved INI
+  - SAFETY: tests MUST NOT touch the repo-root `manualslop_layout.ini`; each test uses its own cwd (per `conductor/code_styleguides/workspace_paths.md`); temp workspace path = `Path("tests/artifacts/_default_layout_install_<pid>")`
+- [x] Task 2.2 [35f22e4d]: Confirm RED (tests fail for install-logic-missing reason); test 3 passes as positive control
+  - WHERE: `tests/test_default_layout_install.py`
+  - HOW: `uv run pytest tests/test_default_layout_install.py -v --tb=short --timeout=120`
+  - Expected: 3 tests fail because no install logic exists yet; the temp-workspace INI is empty or absent post-launch
+- [x] Task 2.3 [f3cd7bc2]: Implement `_install_default_layout_if_empty` helper
+  - WHERE: new module-level function `_install_default_layout_if_empty(src_ini: Path, dst_ini: Path) -> Result[bool]` near `_diag_layout_state` (`src/gui_2.py:584-615`)
+  - WHAT: reads `src_ini` text, decides if `dst_ini` is "missing/empty" (file size < 1000 bytes OR zero `[Window][` lines), copies bundled → dst on true, returns Result[True]; on false returns Result[False]; on `OSError` returns Result with ErrorInfo per `conductor/code_styleguides/error_handling.md`
+  - HOW: `shutil.copy2` for atomic copy; `sys.stderr.write(f"[GUI] installed default layout: {src_ini} -> {dst_ini}\n")` for the user-visible log
+  - SAFETY: thread-safe (no shared state); pure file I/O; 1-space indentation per project rule
+- [x] Task 2.4 [3d87f8e7]: Wire the helper into `App._post_init`
+  - WHERE: `src/gui_2.py:570-582` (`App._post_init` body)
+  - WHAT: call `_install_default_layout_if_empty` BEFORE `_diag_layout_state`; append ErrorInfo to `app._startup_timeline_errors` if `not result.ok`
+  - HOW: `install_result = _install_default_layout_if_empty_result(app, src_path, dst_path)`; if not ok, drain via `_startup_timeline_errors` per the existing pattern at line 580-582
+  - SAFETY: `_post_init` runs on the main thread (HelloImGui callback), no race
+- [x] Task 2.5 [f3cd7bc2]: Add drain helper `_install_default_layout_if_empty_result`
+  - WHERE: `src/gui_2.py` near other drain helpers (line 1448 area: `_post_init_callback_result`)
+  - WHAT: `Result[None]` wrapper for the install; mirrors the existing `Result`-returning pattern for `_post_init_callback_result` and `_diag_layout_state_ini_text_result`
+  - HOW: same pattern; signature `def _install_default_layout_if_empty_result(app, src_path, dst_path) -> Result[bool]`
+  - SAFETY: append-to-drain convention per `conductor/code_styleguides/error_handling.md`
+- [x] Task 2.6 [3d87f8e7]: Verify phase 2.1 tests now pass
+  - WHERE: `tests/test_default_layout_install.py`
+  - HOW: `uv run pytest tests/test_default_layout_install.py -v --tb=short --timeout=120`
+  - Expected: all 3 pass; the post-launch INI has 7+ `[Window][X]` entries
+- [x] Task 2.7 [35f22e4d]: Run adjacent tests/test_gui*.py batch — 8/8 PASSED (test_gui2_layout + test_gui_diagnostics + test_layout_reorganization)
+- [x] Task 2.8 [3d87f8e7]: Commit phase 2 with git note
+  - WHAT: `fix(gui): install default layout when cwd/manualslop_layout.ini is empty`
+  - HOW: standard atomic commit; git note = "Installs bundled `layouts/default.ini` (resolved via the new src/layouts.py path resolution) to cwd when the user's INI is missing or empty, restoring visible panels on first-run / post-deletion. Drains errors to `_startup_timeline_errors` per data-oriented convention."
+- [N/A] Task 2.9: User Manual Verification — DEFERRED to post-merge interactive session (requires desktop screenshot observation; cannot be performed in headless Tier 2 sandbox). The automated test coverage (3/3 install behaviors + 8/8 regression) provides high confidence the fix is correct; user-visible verification is the final acceptance gate.
+
+## Phase 3: Remove hardcoded test-fixture path from production code
+
+Focus: `src/commands.py:369-376` references `tests/artifacts/live_gui_workspace/manualslop_layout.ini`; this is dead code in production + violates the user's "production code MUST NOT reference test-fixture paths" principle (and the 2026-06-29 reinforcement: "the codebase should default to the immediate directory for initial tomls").
+
+- [ ] Task 3.1: Write failing test for `reset_layout` path cleanup
+  - WHERE: new file `tests/test_reset_layout.py`
+  - WHAT: red phase — verify `reset_layout` only consults the cwd-relative path
+    1. `test_reset_layout_only_targets_cwd_ini` — set cwd to a clean temp dir; write `<temp>/manualslop_layout.ini`; create `<temp>/tests/artifacts/live_gui_workspace/manualslop_layout.ini` (decoy); invoke `reset_layout(app)` on a mock app with `show_windows = {}`; use `inspect.getsource(commands.reset_layout)` to assert the string `tests/artifacts/live_gui_workspace` does not appear in `reset_layout`'s source
+  - HOW: instantiate a minimal `App`-like mock with `show_windows = {}`; import `commands` directly (it has `inspect`-friendly source); pure unit test, no live_gui spawn
+  - SAFETY: no real GUI render; the test reads source via `inspect.getsource()`
+- [ ] Task 3.2: Run phase 3.1 tests; confirm RED
+  - HOW: `uv run pytest tests/test_reset_layout.py -v --tb=short`
+  - Expected: test fails because the current `reset_layout` source contains `tests/artifacts/live_gui_workspace` (the hardcoded path the user flagged)
+- [ ] Task 3.3: Remove the hardcoded path from `commands.reset_layout`
+  - WHERE: `src/commands.py:369-376`
+  - WHAT: `layout_paths = ["manualslop_layout.ini"]` (drop the `os.path.join("tests", ...)` line)
+  - HOW: `manual-slop_edit_file` with `old_string` containing both `layout_paths = [` and the `os.path.join(...)` line; replace with `layout_paths = ["manualslop_layout.ini"]`
+  - SAFETY: shrinks the function; no behavior change for end users (cwd-relative was the only functional path)
+- [x] Task 3.4 [3b966288]: Update `commands.reset_layout` docstring (line 351-362; simplified from 5 to 3 lines)
+  - WHERE: `src/commands.py:351-362`
+  - WHAT: simplify the docstring; drop the phrase "deletes manualslop_layout.ini so hello_imgui regenerates a fresh" if no longer accurate
+  - HOW: minimal edit via `manual-slop_edit_file`
+  - SAFETY: docstring only, no behavior change
+- [x] Task 3.5 [3b966288]: Verify phase 3.1 tests now pass — 2/2 PASSED (test_reset_layout_excludes_test_fixture_path, test_reset_layout_runs_on_clean_app)
+- [x] Task 3.6 [3b966288]: Run adjacent test_batch (test_reset_layout + test_commands_no_top_level_command_palette) — 6/6 PASSED
+- [x] Task 3.7 [3b966288]: Commit phase 3 with git note (3b966288 chore(commands): remove dead test-fixture path from reset_layout)
+
+## Phase 4: Verification

+# Track Specification: Default Layout Install + Hardcoded Path Cleanup
+
+## Overview
+
+Manual Slop's GUI panels become invisible at startup whenever `manualslop_layout.ini` is missing, empty, or refers to window names that don't exist in the current build. The root cause is structural: `imgui.begin("Panel Name")` creates a **floating** window with no docking info when the INI has no `[Window][Panel Name] + DockId` entry. Floating windows get default positions that overlap the menu bar or get clipped by the full-screen dockspace, so users see "nothing" while the Windows menu (which reads `app.show_windows`) still shows the panels as "checked."
+
+The pre-existing workaround in `tests/conftest.py:700-712` ships a known-good layout into the test workspace at every session. There is no equivalent installation path for end-user launches — first-run, post-deletion, and post-corrupt-INI users all land in the same broken state. This track ships the equivalent installation path for production launches **AND** introduces the `layouts/` directory at the repo root (parallel to `themes/`) as the canonical home for default layout assets. It also removes a hardcoded `tests/artifacts/...` path that escaped into `src/commands.py`.
+
+**Two patterns established by this track:**
+
+1. **`layouts/` directory pattern (the immediate deliverable):** Same shape as `themes/` — bundled assets at repo root, path resolution via `src/paths.py`, loaders in a parallel `src/` module. Sets up the directory structure for the eventual Fleury-style migration below.
+
+2. **Fleury "type view" / "lens" pattern (the eventual normalization target, NOT in this track):** The user's stated long-term direction is to define GUI panels as declarative "constructs" — data tables of `(panel_name, render_callable, dock_target)` tuples that the renderer iterates per-frame, similar to how Ryan Fleury defines **type views** ("lenses in the code, but views to the user") in the rad debugger to say "if you have this type, just do that automatically for me" (verified from the rad debugger talk transcripts stored at `docs/transcripts/rcJwvx2CTZY_ryan_fleury_raddbg_codebase_intro.json` v1@2241s and `docs/transcripts/_9_bK_WjuYY_ryan_fleury_raddbg_walkthrough.json` v2@7697s; see "Eventual Normalization Target" below). The current track **does not** migrate the GUI definitions — it just sets up the layout asset home so the future migration has somewhere to land.

+
+### Already Implemented (DO NOT re-implement)
+
+- **`themes/` directory + path/loader stack (the PARALLEL pattern this track mirrors):**
+  - `themes/` at repo root contains 8 built-in themes (`nord_dark.toml`, `monokai.toml`, etc.). The directory lives at repo root, **not** under `src/` — per the user's "don't put configs in `src/`" directive.
+  - `src/paths.py:60` declares `themes: Path`; `src/paths.py:83` resolves it to `root_dir / "themes"`; `src/paths.py:150` adds `SLOP_GLOBAL_THEMES` env override + config-file override on top of the default.
+  - `src/theme_models.py:181-225` defines `load_themes_from_dir(path, scope)` and `load_themes_from_toml(path, scope)` — directory + file loaders, both returning `Result`-wrapping `dict[str, ThemeFile]`.
+  - `src/theme_2.py:340-346` calls `load_themes_from_disk()` which iterates `cfg.themes` and merges `load_themes_from_dir(...)` per scope.
+  - The 4-function pattern: declare `Path` on the config dataclass, resolve in `initialize_paths`, expose a `get_themes_dir()` accessor, load via the dedicated module.
+
+- **`tests/artifacts/manualslop_layout_default.ini`** (109 lines, 2699 bytes) — pre-baked default layout with explicit `DockId` entries for Project Settings, Files & Media, AI Settings, Operations Hub, Discussion Hub, Log Management, Diagnostics, Theme, and the four MMA tier panels (collapsed). Three-column split: DockSpace `0xAFBEEF01` with DockNodes `0x10` (left, 4 tabs) and `0x11` (right, 6 tabs). Docstring lists the iter-step procedure: "open sloppy.py, arrange, quit (HelloImGui auto-saves), copy resulting INI over this one."
+
+- **`live_gui` fixture ships the default layout** (`tests/conftest.py:700-712`): copies `tests/artifacts/manualslop_layout_default.ini` to `temp_workspace / "manualslop_layout.ini"` before spawning `sloppy.py --enable-test-hooks`. Comment at line 700-705 explicitly documents the failure mode:
+  > "Without this, HelloImGui auto-docks on first launch in a non-deterministic way, and the user's saved repo-root layout references stale pre-hub-refactor window names."
+
+- **`App._diag_layout_state()`** (`src/gui_2.py:584-615`) — one-shot startup diagnostic that logs `show_windows` entries, visible-by-default windows, and warns about stale `[Window][...]` entries in the INI that reference post-refactor-renamed windows (e.g. "Projects", "Files", "Screenshots", "Discussion History", "Provider", "Message", "Response", "Tool Calls", "Comms History", "System Prompts"). Already wired into `_post_init` at line 580.
+
+- **`commands.reset_layout`** (`src/commands.py:342-378`) — sets every `show_windows[*]` to True and deletes the layout INI. Docstring (line 351-362) acknowledges: "User will need to restart sloppy.py for the dock layout to fully take effect."
+
+- **HelloImGui save on shutdown** (`src/gui_2.py:1494-1515` via `_shutdown_save_ini_result`, called from `App.shutdown` line 972-973): `imgui.save_ini_settings_to_disk(app.runner_params.ini_filename)` writes whatever ImGui has in its settings registry. **Empirical evidence shows it only writes `[Window][Debug##Default]` if no window was given a `DockId` and persisted position** (verified via 8s run with show_windows=True for 9 panels → 585-byte INI).
+
+- **`ini_filename` resolution** (`src/gui_2.py:681`): `self.runner_params.ini_filename = "manualslop_layout.ini"` — relative to cwd. `ini_folder_type = IniFolderType.current_folder` on line 680. HelloImGui resolves this to `<cwd>/manualslop_layout.ini`.
+
+- **Test workspace isolation** (`tests/conftest.py:660-666`): per-run workspace lives under `tests/artifacts/_live_gui_workspace_<timestamp>/`, sets up its own `manual_slop.toml` + `conductor/tracks/` + `config.toml`.
+
+### Gaps to Fill (This Track's Scope)
+
+- **GAP-1: No production-side default-layout installer.** When `manualslop_layout.ini` is missing or empty AND the user launches `sloppy.py` outside the test harness, the app does not install a sane default. HelloImGui auto-creates a fresh INI with only `[Window][Debug##Default]` and an empty dockspace. The user's saved `show_windows` flags (default-true for 9 panels) are honored by `_render_window_if_open` calls but the resulting `imgui.begin(...)` calls produce invisible floating windows. The conftest's well-known workaround is not exposed to production launches.
+
+- **GAP-2: Hardcoded test-fixture path in production code.** `src/commands.py:371` contains `os.path.join("tests", "artifacts", "live_gui_workspace", "manualslop_layout.ini")` inside the `reset_layout` command. This path only exists inside the test runner's per-session workspace. From a production cwd of `C:\Users\Ed\Projects\foo\`, the `tests/artifacts/live_gui_workspace/...` lookup will silently fail and only the first (cwd-relative) path is checked. The second path is dead code in production and a misplaced test-path reference in production source — violates the user's principle: **"the codebase should default to the immediate directory for initial tomls"** (2026-06-29 feedback) and the existing rule "production code MUST NOT reference test fixture paths."
+
+- **GAP-3: No `layouts/` directory + path/loader stack.** Right now the only "default layout" lives in `tests/artifacts/` — wrong location, wrong owner. The themes system has the full pattern (`themes/` + `src/paths.py` declaration + `src/theme_models.py`/`src/theme_2.py` loaders); the layouts system has nothing. This track ships the analogous `layouts/` + `src/layouts.py` stack so the layouts home is parallel to themes, not buried under `tests/artifacts/` and not under `src/`.
+
+- **GAP-4: No regression test for the visibility-after-empty-INI scenario.** The existing `test_workspace_profiles_sim.py::test_workspace_profiles_restoration` and `test_gui_text_viewer.py::test_text_viewer_state_update` test workspace/profile state via the API but do NOT verify that `imgui.begin(...)` actually registers a docked window (i.e., that the layout INI grows the expected `[Window][X] + DockId` entries after a render). Without an INI-content regression test, GAP-1 can regress silently.
+
+## Goals
+
+- **G1.** When `sloppy.py` (production) launches and `cwd/manualslop_layout.ini` is missing OR contains 0 `[Window][` entries OR is under 1000 bytes (heuristic for "effectively empty"), `App._post_init` SHALL install `layouts/default.ini` (the bundled asset) to `cwd/manualslop_layout.ini` BEFORE HelloImGui loads it. The log output shall include `[GUI] installed default layout: <src> -> <dst>` so users can see what happened.
+
+- **G2.** `App._post_init` SHALL respect the user's `show_windows` overrides from `config.toml` when installing the default layout (the install ONLY writes the INI; it does NOT mutate `app.show_windows`). The default-true windows (`Project Settings`, `Files & Media`, `AI Settings`, `Discussion Hub`, `Operations Hub`, `Theme`, `Log Management`, `Diagnostics` per `_default_windows` in `src/app_controller.py:2086-2108`) SHALL be visible after install because the bundled `layouts/default.ini` references exactly those names with `DockId` entries.
+
+- **G3.** `commands.reset_layout` (`src/commands.py:342-378`) SHALL remove the hardcoded `tests/artifacts/...` path from its `layout_paths` list, leaving only the cwd-relative `"manualslop_layout.ini"`. The `live_gui` workspace path is owned by the test fixture, not the app.
+
+- **G4.** A new `layouts/` directory at repo root SHALL exist parallel to `themes/`. The new asset `layouts/default.ini` SHALL be a `git mv` of `tests/artifacts/manualslop_layout_default.ini` (preserving git history). The `src/paths.py` config dataclass SHALL add a `layouts: Path` field (parallel to `themes: Path`); initialize_paths SHALL resolve `layouts = root_dir / "layouts"` with `SLOP_GLOBAL_LAYOUTS` env override + config-file override on top, mirroring the themes pattern at line 60 + 83 + 150.
+
+- **G5.** A new `src/layouts.py` module SHALL be added (parallel to `src/theme_2.py`/`src/theme_models.py`), exposing at minimum:
+  - `get_layouts_dir() -> Path` accessor
+  - `load_layouts_from_disk() -> dict[str, LayoutFile]` reader, returning a `Result`-wrapped dict (per data-oriented convention; per the existing `theme_models.load_themes_from_dir` shape)
+  - The `LayoutFile` dataclass as a `@dataclass(frozen=True, slots=True)` per the project's C11/Odin/Jai-in-Python value-type mandate (no `dict[str, Any]`)
+  - **No new `.py` file beyond this `src/layouts.py`; the loader reuses the existing `Result[T]` plumbing in `src/result_types.py` and follows the `theme_models.load_themes_from_*` contract** (per the file-naming convention in `conductor/workflow.md`: helpers for an existing system go in the system module — and `layouts/` is the system being introduced).
+
+- **G6.** Add `tests/test_default_layout_install.py` that:
+  - Removes `cwd/manualslop_layout.ini` and verifies the app installs the default on launch
+  - Runs the app for ≥ 5 seconds via `subprocess.Popen(sloppy_args, cwd=temp_workspace)` (mirrors the conftest pattern at line 792), then terminates the subprocess
+  - Asserts the saved INI contains `[Window][Project Settings]` with a `DockId=` line
+  - Asserts the saved INI contains ≥ 7 of the 9 default-visible windows
+  - Does NOT depend on the `imgui_test_engine` (which is a separate follow-up track per `conductor/tracks/test_engine_integration_20260627/spec.md`)
+
+- **G7.** Add `tests/test_reset_layout.py` that asserts `commands.reset_layout`'s source has no `tests/artifacts/...` string and only consults the cwd-relative `"manualslop_layout.ini"`. Does not depend on launching the app (pure unit test on the function source).
+
+- **G8.** Update `tests/conftest.py:709` to read the bundled layout from `layouts/default.ini` (new path) instead of `tests/artifacts/manualslop_layout_default.ini` (old path). The test fixture continues to work; only the source-of-truth path changes.
+
+## Non-Functional Requirements
+
+- **No configs in `src/`** — per the user's explicit directive (2026-06-29): `.ini` config files live at repo root (`themes/`, `layouts/`, `config.toml`, etc.), not under `src/`. The loaders (Python code) DO live in `src/`, but the bundled assets they read do NOT.
+
+- **No day estimates** in track artifacts (per `conductor/workflow.md` §"Tier 1 Track Initialization Rules" — HARD BAN).
+
+- **No opaque types** in new code (per `conductor/code_styleguides/data_oriented_design.md` §8.5 — Python Type Promotion Mandate). The new `LayoutFile` dataclass uses `@dataclass(frozen=True, slots=True)` with explicit fields. The `dict[str, Any]` BANNED pattern from `conductor/code_styleguides/python.md` §17 is explicitly avoided; loaders return `dict[str, LayoutFile]` (typed instances, not opaque dicts).
+
+- **Mirror the `themes/` pattern faithfully** — the new `src/layouts.py` should re-use the `load_themes_from_dir` shape: function signature takes `(path, scope)`, returns `dict[str, LayoutFile]`, drained via `_layout_err = Result(...)`. This makes future code that needs to iterate layouts/ parallel to iterate themes/ follow the same pattern (per `conductor/code_styleguides/feature_flags.md` "delete to turn off": a missing `layouts/` directory or a malformed INI returns the empty dict, not an exception).
+
+- **Atomic per-task commits** with git notes (per `conductor/workflow.md` §"Task Workflow" step 9-10).
+
+## Architecture Reference
+
+- **`themes/` mirror pattern (the canonical reference):**
+  - `src/paths.py:60` — `themes: Path = ...` field on the config dataclass
+  - `src/paths.py:83` — `root_dir / "themes"` default in the resolve function
+  - `src/paths.py:150` — `SLOP_GLOBAL_THEMES` env override + config override
+  - `src/paths.py:210-216` — `get_themes_dir()` accessor functions
+  - `src/theme_models.py:181-225` — `load_themes_from_dir(path, scope)` and `load_themes_from_toml(path, scope)` returning `dict[str, ThemeFile]`
+  - `src/theme_2.py:340-346` — `load_themes_from_disk()` consumer of the dir loader
+
+- **Why `layouts/` not `src/default_layout/`:** the user explicitly rejected putting `.ini` config files in `./src/` (2026-06-29 directive: "I don't want the codebase ./src to have configuration files"). The themes system pre-existed this directive and already lives at repo root — the layouts system follows that precedent.
+
+- **HelloImGui IniFolderType / save_ini_settings_to_disk:** `src/gui_2.py:680-681`, `src/gui_2.py:1494-1515`. The `_shutdown_save_ini_result` helper at line 1494 is the canonical save path; the new install runs in `_post_init` BEFORE `immapp.run(...)` (which happens after `_post_init` at `src/gui_2.py:1486`).
+
+- **`_diag_layout_state` (`src/gui_2.py:584-615`):** emit a one-shot log line `[GUI] installed default layout: <src> -> <dst>` from `_post_init` after a successful install so the diagnostic already runs at the right time. The existing diagnostic continues to log state AFTER install, so the log order tells the user the install happened.
+
+- **`_render_window_if_open` (`src/gui_2.py:1115-1120`):** the `_post_init` install runs before `immapp.run(...)`, which means HelloImGui loads the installed INI on the next frame and the `[Window][Project Settings] + DockId=` entries are honored by `imgui.begin(...)`. No change to `_render_window_if_open` is needed — the existing call site (`src/gui_2.py:1832-1855` in `render_main_interface`) already passes `show_windows[name]` correctly.
+
+- **`conductor/code_styleguides/error_handling.md`:** the install is best-effort. On `OSError` / `FileNotFoundError` (asset missing in the wheel), append to `app._startup_timeline_errors` and continue (the user gets a normal first-run experience, panels may not appear, but the app does not crash).
+
+## Eventual Normalization Target (Fleury "View Constructs" — out of scope for this track)
+
+The user's stated long-term direction (2026-06-29, with reference to Ryan Fleury's raddbg talks at `https://youtu.be/rcJwvx2CTZY` and `https://youtu.be/_9_bK_WjuYY`, transcripts at `docs/transcripts/rcJwvx2CTZY_ryan_fleury_raddbg_codebase_intro.json` and `docs/transcripts/_9_bK_WjuYY_ryan_fleury_raddbg_walkthrough.json`):
+
+> "Eventually I wanted to adopt Ryan Fleury's way of defining view constructs like he has with the rad debugger... I don't need to full on convert the gui definitions in the codebase to this way of defining them but just something to keep in mind as its the eventual normalization target for how I treat these panel definitions."
+
+**The pattern, extracted from the transcripts:**
+- v1@2237s: Ryan calls `imgui.begin("Window", p_open)` and the type-view system runs: "a view type view is just saying, 'If you have this type, just do that automatically for me.'"
+- v2@7697s: Ryan renames them: "lenses in the code but to the users they're just called views... the type view is just saying... if you have this type, just do that automatically for me."
+- The pattern is **declarative**: each panel/widget is a data table of `(name, render_callable, dock_target, default_visible, pops_out)` entries that the render loop iterates per-frame. The codebase stops having scattered `_render_window_if_open("X", lambda: render_x(app))` calls and replaces them with one `for panel in PANELS: if app.show_windows.get(panel.name): panel.render(app)`.
+
+**Why this track sets up that future:**
+1. **`layouts/` at repo root** = the home for the declarative asset (eventually a `.py` module alongside, or a TOML/INI with panel-by-panel config).
+2. **`src/layouts.py` as a typed loader** = the precedent that "config + loader" is the canonical way to define layout state, instead of hardcoded imperative blocks in `gui_2.py`.
+3. **`layouts/default.ini` keyed by panel NAME (`[Window][Project Settings]`)** = the name strings are already the keys; the future migration to `PANELS: tuple[PanelDef, ...]` will keep those names but add `render_callable` and `dock_target` fields.
+
+**What this track does NOT do** (explicitly deferred): migrate the ~40 `render_x` functions in `src/gui_2.py` into declarative `PanelDef` records. That's a much larger refactor (touching ~3000 lines of GUI code) that needs its own dedicated track per the user ("[don't need to] full on convert... just something to keep in mind"). Logged in `metadata.json:deferred_to_followup_tracks` for the next planner.
+
+## Out of Scope
+
+- **Replacing layout state via `imgui_test_engine`** (`conductor/tracks/test_engine_integration_20260627/spec.md`) — this is a separate follow-up track. G6's regression test uses INI content as a proxy for "imgui.begin was called and registered a docked window", not pixel-level visual regression.
+- **Migrating panel definitions to Fleury-style `PanelDef` data records** — see "Eventual Normalization Target" above; tracked in `metadata.json:deferred_to_followup_tracks[].panel_defs_fleury_migration`.
+- **Auto-iterating layout per user agent role** (`docs/guide_workspace_profiles.md:Contextual Auto-Switch`) — separate feature; the per-track `Contextual Auto-Switch` opt-in lives behind `ui_auto_switch_layout` and uses WorkspaceProfiles, not the per-window INI.
+- **Refreshing `_diag_layout_state` thresholds** — the existing "stale window" warn set (line 605: `_STALE_WINDOW_NAMES = {"Projects", ...}`) is unchanged by this track.
+- **WorkspaceProfile save/load** — orthogonal; profile save captures `show_windows` + `ini_content`, profile load applies them via `imgui.load_ini_settings_from_memory` (`src/gui_2.py:927`). The install on first run does not interact with profiles.
+- **Layout editing UI** (`src/gui_2.py:render_operations_hub` "Workspace Layouts" tab) — unchanged.
+- **Adding more than one bundled layout to `layouts/`** — `default.ini` is enough for this track; users can hand-author `my-layout.ini` and switch via WorkspaceProfile. Future track may add `compact.ini`, `wide.ini`, etc.
+

+## Phase 1: Restore the bundled INI to a working structure
+
+Focus: replace the broken `layouts/default.ini` (Tier 2's `e9654518` stripped the `[Docking]` block + per-window `DockId` references) with a working version that mirrors the user's working `manualslop_layout.ini` on master.
+
+- [x] Task 1.1 [read]: Read user's working INI as the template
+  - WHERE: `manualslop_layout.ini` on master branch (2150 bytes)
+  - RESULT: read - confirms full structure (DockSpace ID=0xAFC85805, 2 DockNodes 0x00000001 + 0x00000002, 9 windows with per-window DockId)
+- [x] Task 1.2 [read]: Identify the runtime DockSpace ID + DockNode ID space
+  - WHERE: `manualslop_layout.ini` SplitIds line at the bottom
+  - RESULT: confirmed - `MainDockSpace:2949142533` = `0xAFC85805` (the literal ID HelloImgui looks for)
+- [x] Task 1.3 [read]: Inventory the canonical visible windows to dock
+  - WHERE: `src/app_controller.py:2083-2108` (`_default_windows` dict)
+  - RESULT: emitted default-visible set = 8 (default-true non-stale non-Tier-1-4 windows): Project Settings, Files & Media, AI Settings, Theme, Operations Hub, Discussion Hub, Log Management, Diagnostics (Response is in _STALE_WINDOW_NAMES so omitted; Tier 1: Strategy / 2: Tech Lead / 3: Workers / 4: QA disabled by config.toml)
+- [x] Task 1.4 [read]: Inventory the must-NOT-appear names
+  - WHERE: `src/gui_2.py:603-607` (`_STALE_WINDOW_NAMES` set)
+  - RESULT: bundled INI has zero _STALE_WINDOW_NAMES entries (verified by grep); Response scrubbed from template
+- [x] Task 1.5 [2afb0126]: Write the new `layouts/default.ini`
+  - RESULT: 2971 bytes (close to user's working 2150 + extra comment header)
+  - Contains: 8 [Window][...] headers + per-window DockId lines + [Docking][Data] with DockSpace ID=0xAFC85805 + 2 DockNode children + SplitIds line
+- [x] Task 1.6 [2afb0126]: Replace the misleading comment block
+  - RESULT: replaced e9654518 "auto-dock layer" claim with accurate mechanism description (DockSpace 0xAFC85805 = runtime MainDockSpace, DockId lines tell HelloImgui which DockNode, literal IDs stable, "auto-dock without DockIds is a misconception")
+- [x] Task 1.7 [2afb0126]: Commit phase 1 with git note (combined with Phase 2 as `2afb0126 fix(layout): restore [Docking] structure + per-window DockId references in bundled INI`)
+
+## Phase 2: Flip the test assertions
+
+Focus: `e9654518` weakened `tests/test_default_layout_install.py` to assert the OPPOSITE of what we want (no `[Docking]` block = good). Flip those assertions.
+
+- [ ] Task 2.1: Find and read current test assertions
+  - WHERE: `tests/test_default_layout_install.py` (e9654518's test update)
+  - WHAT: find the 3 tests updated by e9654518; identify which assertions assert "no `[Docking]` block" or "no DockId" — those are inverted and need flipping
+  - HOW: `Select-String -Path tests/test_default_layout_install.py -Pattern "no [Docking]|no DockId|strip.*Docking"` to find the inverted assertions
+  - SAFETY: pure read
+- [ ] Task 2.2: Flip the "no Docking block" assertion to "Docking block exists"
+  - WHERE: `tests/test_default_layout_install.py`, the test that asserts "no `[Docking]` block"
+  - WHAT: replace with the positive assertion: "the bundled INI contains `[Docking][Data]` with `DockSpace ID=` + at least one `DockNode ID=` child"
+  - HOW: `manual-slop_edit_file` with surgical find-replace; preserve 1-space indent
+  - SAFETY: test-only change; verify by running the test before/after
+- [ ] Task 2.3: Flip the "no DockId per window" assertion to "DockId per visible window"
+  - WHERE: `tests/test_default_layout_install.py`, the test that asserts windows have no `DockId=`
+  - WHAT: replace with the positive assertion: "every default-visible window in the bundled INI has a `DockId=0x00000001,N` or `DockId=0x00000002,N` line"
+  - HOW: same approach as Task 2.2; ideally re-write to iterate `app_controller._default_windows` keys that are True and assert each has a DockId
+  - SAFETY: test-only
+- [ ] Task 2.4: Run the test suite — RED expected, then GREEN
+  - WHERE: `tests/test_default_layout_install.py`
+  - WHAT: `uv run pytest tests/test_default_layout_install.py -v --tb=short --timeout=120`
+  - Expected after Task 2.1-2.3: GREEN (the new INI from Phase 1 has the right structure; the flipped assertions now match it)
+  - SAFETY: standard test run; per `conductor/workflow.md` use the batched runner for batch verification: `uv run python scripts/run_tests_batched.py --filter test_default_layout_install`
+- [x] Task 2.5 [79c25a32 + earlier passes]: Run adjacent test batches -- 17/17 PASSED across test_default_layout_install + test_reset_layout + test_gui2_layout + test_gui_diagnostics + test_layout_reorganization + test_commands_no_top_level_command_palette
+- [x] Task 2.6 [79c25a32]: Commit phase 2 with git note (combined with the pre-run-install fix; the test assertion flip landed in 2afb0126)
+
+## Phase 3: Update Tier 2's TRACK_COMPLETION report with the FOLLOWUP addendum
+
+Focus: Tier 2 wrote `docs/reports/TRACK_COMPLETION_default_layout_install_20260629.md` claiming the track shipped successfully. Add a FOLLOWUP addendum noting that the INI-stripping half of `e9654518` was wrong, and that this followup track (`default_layout_install_followup_20260629`) is the correction.
+
+- [ ] Task 3.1: Read the existing TRACK_COMPLETION report
+  - WHERE: `docs/reports/TRACK_COMPLETION_default_layout_install_20260629.md`
+  - WHAT: confirm what Tier 2 claimed (especially the "all phases shipped" / "panels visible post-install" claims)
+  - HOW: `Get-Content` the file; note the section headings so the addendum can be appended in a coherent place
+  - SAFETY: pure read
+- [ ] Task 3.2: Append FOLLOWUP addendum
+  - WHERE: end of `docs/reports/TRACK_COMPLETION_default_layout_install_20260629.md`
+  - WHAT: add a section titled "FOLLOWUP: `default_layout_install_followup_20260629` (post-merge correction)" with:
+    - Summary: Tier 2's `e9654518` strip-the-docking fix was based on a wrong theory; the new followup track restores the `[Docking]` + per-window `DockId` references
+    - Diagnosis: literal IDs in INI ARE used by HelloImGui (when INI exists); without `[Docking]` children + `DockId` lines, the dockspace is empty and panels don't render
+    - Evidence: user's working master INI is 2150 bytes with full structure; Tier 2's broken INI is 1447 bytes without it; first-launch screenshots confirm 0 vs all panels
+    - Action: see `conductor/tracks/default_layout_install_followup_20260629/spec.md` for the full correction
+    - Status of `e9654518`'s "good half" (live-session `load_ini_settings_from_memory()` apply): KEPT — that's still the right fix
+  - HOW: `manual-slop_edit_file` with `old_string` = last paragraph of the report, `new_string` = last paragraph + new section
+  - SAFETY: append-only; do not rewrite Tier 2's content
+- [ ] Task 3.3: Commit phase 3 with git note
+  - WHAT: `docs(reports): add FOLLOWUP addendum to TRACK_COMPLETION noting e9654518 INI strip was wrong`
+  - HOW: standard atomic commit
+  - SAFETY: doc-only
+
+## Phase 4: Empirical verification + checkpoint
+
+Focus: prove the fix actually works by spawning the app on the corrected branch and confirming panels render.
+
+- [ ] Task 4.1: Spawn sloppy.py on the fixed branch, observe via screenshot
+  - WHERE: Tier 2's working tree at `tier2-clone/tier2/default_layout_install_20260629` after this track's 3 commits
+  - WHAT: `cd C:\projects\manual_slop_tier2 && uv run python sloppy.py` (or use `start sloppy.py`); observe via screenshot that the 9 default-visible panels actually render (Project Settings, Files & Media, AI Settings, Discussion Hub, Operations Hub, Theme, Log Management, Diagnostics, Response — wait, Response is NOT default-true in `_default_windows`; the 9 visible-by-default per the diagnostic = 9 default-true windows, NOT including `Response`)
+  - HOW: launch + screenshot capture (the user can do this manually; or the worker can use a headless render and INI-content assertion via `live_gui`)
+  - SAFETY: spawn + observe + kill (don't leave dangling process)
+- [ ] Task 4.2: Check the saved INI post-launch matches the expected structure
+  - WHERE: `C:\projects\manual_slop_tier2\manualslop_layout.ini` after the test launch
+  - WHAT: assert the INI has:
+    - 9 (or 12) `[Window][X]` entries (one per default-visible window)
+    - All have `DockId=0x00000001,N` or `0x00000002,N`
+    - `[Docking][Data]` block with `DockSpace ID=0xAFC85805` + 2 `DockNode` children
+    - **No** `[GUI] WARNING: layout has N stale window name(s)` in the stderr log
+    - File size ~2200 bytes (vs the broken 1447)
+  - HOW: read the file + the startup log
+  - SAFETY: pure read
+- [ ] Task 4.3: Checkpoint commit + verification git note
+  - WHAT: `conductor(checkpoint): end of default_layout_install_followup_20260629 (Docking restored, panels render empirically)`
+  - HOW: standard atomic commit with empty body; attach a long-form git note documenting the diagnosis, the 3-phase fix, the empirical screenshot evidence, and the recommended merge action (cherry-pick `5ad062b1..HEAD` from tier2 branch onto master)
+  - SAFETY: empty commit allowed per `conductor/workflow.md` §"Phase Completion Verification"
+- [ ] Task 4.4: Update `state.toml` to mark all phases complete
+  - WHERE: `conductor/tracks/default_layout_install_followup_20260629/state.toml`
+  - WHAT: set every phase status to "completed" + every task to "completed" + the verification flags to true

+# Track Specification: Default Layout Install — Followup (Restore Docking Structure)
+
+## Overview
+
+The `default_layout_install_20260629` track shipped with a follow-up fix (`e9654518 fix(layout): strip stale dockspace IDs from bundled INI; force live-session apply`) that turned out to be based on a wrong theory of how HelloImGui dockspace IDs work. The fix stripped the `[Docking]` data block AND every per-window `DockId=` line from `layouts/default.ini`, replacing them with a comment block claiming HelloImGui would "auto-dock" the panels via its central dockspace.
+
+**It does not work.** Empirically verified against `tier2-clone/tier2/default_layout_install_20260629` HEAD (`e9654518`):
+
+- `manualslop_layout.ini` after first launch is **1447 bytes**, contains only a `[Docking]` block with `DockSpace ID=0xAFC85805` and `CentralNode=1`. **No `DockNode` children. No per-window `DockId` lines.**
+- User-visible result: empty dockspace with only the menu ribbon; **9 default-visible panels are NOT rendered** (verified via screenshot 2026-06-29).
+
+By contrast, the user's working main repo `manualslop_layout.ini` is **2150 bytes** and contains a full `[Docking]` block with `DockSpace` + **2 `DockNode` children** (`0x00000001` CentralNode + `0x00000002` sibling) **and every visible window has a `DockId=0x00000001,N` or `0x00000002,N` line**. Panels render. The only warning is a "stale `Response` window name" because `_STALE_WINDOW_NAMES = {... "Response", ...}` was updated post-refactor but the user's INI was preserved from a pre-refactor session.
+
+The follow-up tracks Tier 2's `e9654518` commit and replaces the broken `layouts/default.ini` with a properly-structured version. It also adds an end-to-end "render-time" test that asserts panels are actually rendered (not just that the INI has DockIds) — the original `e9654518` test was weakened to assert "no `[Docking]` block exists," which would happily pass even when no panels render.
+
+**Tier 2 already shipped everything else correctly** — Phase 1 (`layouts/` + `src/layouts.py` mirroring themes/), Phase 2 (install helper + drain wiring), Phase 3 (reset_layout path cleanup), and the **GOOD part of `e9654518`** (live-session `imgui.load_ini_settings_from_memory()` apply — that part IS correct because HelloImGui reads `ini_filename` BEFORE `_post_init` fires, so the live re-apply is needed for same-session visibility). Those stay. Only the `layouts/default.ini` content and the matching test assertions need to change.
+
+## Current State Audit (as of `e9654518` on `tier2-clone/tier2/default_layout_install_20260629`, master `42eb880f`)
+
+### Already Implemented (DO NOT re-implement)
+
+- **`layouts/` directory at repo root + `src/paths.py` `layouts` field + `src/layouts.py` loader** (Phase 1 of `default_layout_install_20260629`, commit `7577d7d2`) — mirrors the `themes/` pattern. The directory exists, the loader reads it, the path resolution works. Verified: `Test-Path C:\projects\manual_slop_tier2\layouts\default.ini` → True.
+
+- **`_install_default_layout_if_empty` helper + `_install_default_layout_if_empty_result` drain helper** (Phase 2, commits `f3cd7bc2` + `3d87f8e7` + `cf5244b1`). The decision rule is correct: "empty INI" = file missing OR size < 1000 bytes OR zero `[Window][` lines → copy bundled → dst.
+
+- **Live-session `imgui.load_ini_settings_from_memory(src_text)` apply after copy** (the GOOD half of `e9654518`, line +1478 in `src/gui_2.py`):
+  ```python
+  # and ALSO calls imgui.load_ini_settings_from_memory(src_text) so the
+  # current live HelloImGui session applies the bundled docking positions
+  # immediately (HelloImGui reads ini_filename BEFORE the post_init callback
+  # fires, so a write-to-disk-only install wouldn't take effect on the
+  # current launch's render loop).
+  ```
+  This part is **correct** and **must stay**. Verified: without this call, even a perfect INI would not take effect on the current launch's render loop (HelloImGui reads cwd INI at `immapp.run()` startup, before `_post_init` runs).
+
+- **`commands.reset_layout` path cleanup** (Phase 3, commit `3b966288`): dead `tests/artifacts/live_gui_workspace/...` reference removed; only cwd-relative `"manualslop_layout.ini"` consulted.
+
+- **`tests/test_reset_layout.py`** (Phase 3): asserts `inspect.getsource(commands.reset_layout)` has no `tests/artifacts/...` string. Passes.
+
+- **`_default_windows` (canonical list)**: `src/app_controller.py:2083-2108` defines which windows exist + their default-visible state. The default-true windows (12) are: `Project Settings`, `Files & Media`, `AI Settings`, `Tier 1: Strategy`, `Tier 2: Tech Lead`, `Tier 3: Workers`, `Tier 4: QA`, `Discussion Hub`, `Operations Hub`, `Theme`, `Log Management`, `Diagnostics`. The default-false windows (10) are: `MMA Dashboard`, `Task DAG`, `Usage Analytics`, `Tier 1`/`Tier 2`/`Tier 3`/`Tier 4` (singular, pre-rename), `Message`, `Response`, `Tool Calls`, `Text Viewer`. **Bundled INI should match this list** — name exactly, default-visible-true entries docked, default-visible-false entries absent (so they don't generate the `[GUI] WARNING: layout has N stale window name(s) that no longer exist` warning).
+
+- **`_STALE_WINDOW_NAMES`** (canonical "must not appear" list): `src/gui_2.py:603-607` defines `{"Projects", "Files", "Screenshots", "Discussion History", "Provider", "Message", "Response", "Tool Calls", "Comms History", "System Prompts"}`. Bundled INI must NOT contain any of these as `[Window][X]` entries or `_diag_layout_state` will emit the stale warning.
+
+- **User's working `manualslop_layout.ini` (2150 bytes, master branch)**: the canonical structure this track must reproduce. Contains:
+  - 9 `[Window][X]` entries: `Project Settings`, `Files & Media`, `AI Settings`, `Theme`, `Discussion Hub`, `Operations Hub`, `Response`, `Log Management`, `Diagnostics` (all default-true + the stale `Response`)
+  - Per-window `DockId=0x00000001,N` or `0x00000002,N` lines (consistent with the DockNode IDs in the same `[Docking]` block)
+  - `[Docking][Data]` block with `DockSpace ID=0xAFC85805` + `DockNode ID=0x00000001` (CentralNode=1) + `DockNode ID=0x00000002` (sibling)
+  - SplitIds line: `{"gImGuiSplitIDs":{"MainDockSpace":2949142533}}` — note `2949142533 = 0xAFC85805`, the runtime-generated MainDockSpace ID
+
+### Gaps to Fill (This Track's Scope)
+
+- **GAP-1: `layouts/default.ini` has NO docking structure** (the core bug). Currently contains only `Pos=...`, `Size=...`, `Collapsed=0` for 12 windows; no `[Docking]` block with DockNode children; no per-window `DockId` lines. When this INI is installed, HelloImGui creates an empty dockspace (no tabs, no children) and the windows float at their `Pos` — but the full-screen dockspace captures the viewport, hiding them all.
+
+- **GAP-2: Tier 2's commit message is misleading future readers**. `e9654518`'s body says "HelloImgui's auto-dock layer places the panels as tabs in the central dockspace on first render" — this claim is FALSE. Without explicit `DockId` references, HelloImGui's central dockspace has no children to dock into. The comment block at the top of `layouts/default.ini` (rewritten by `e9654518`) propagates the same wrong theory into the file itself.
+
+- **GAP-3: `tests/test_default_layout_install.py` assertions are weakened**. `e9654518` updated the tests to assert "no `[Docking]` data block exists" — which is the OPPOSITE of what we want. The next agent reading the test would conclude that "bundled INI without docking structure is correct." The assertions must be flipped: `DockId=` lines SHOULD exist for each visible window; `[Docking][Data]` block SHOULD have DockSpace + at least one DockNode child.
+
+- **GAP-4: No render-time verification**. Both the original spec test (`tests/test_default_layout_install.py`) and Tier 2's `e9654518` follow-up only assert INI *content*, not that panels actually render. The fundamental thing we want to verify is "after install, panels are visible on the current launch." The only honest way to assert this without depending on `imgui_test_engine` (separate track `test_engine_integration_20260627`) is to use the `live_gui` fixture to spawn the app, read back `app.show_windows` (already known correct), then check the saved INI for a real `[Docking]` hierarchy + per-window DockId references. If both are present, panels render (verified empirically against the user's working main repo INI; if absent, panels don't render — verified empirically against Tier 2's broken INI).
+
+## Goals
+
+- **G1.** Replace `layouts/default.ini` (currently 2516 bytes, no docking structure) with a working version (target ~2200 bytes, full `[Docking]` hierarchy + per-window `DockId` references for the 12 default-visible windows). The new file must:
+  - Use the runtime-generated `DockSpace ID=0xAFC85805` (= `2949142533` from the user's working INI SplitIds line) so HelloImGui matches the literal ID against the dockspace it creates
+  - Define 2 `DockNode` children (left column CentralNode=1, right column sibling) with IDs in the same numeric space (`0x00000001` + `0x00000002` work; the exact values don't matter as long as they're consistent within the file)
+  - Reference the 12 default-visible windows with `DockId=0x00000001,N` (left column tabs) and `DockId=0x00000002,N` (right column tabs)
+  - NOT contain any of `_STALE_WINDOW_NAMES` (`Projects`, `Files`, `Screenshots`, `Discussion History`, `Provider`, `Message`, `Response`, `Tool Calls`, `Comms History`, `System Prompts`) — particularly `Response` which the user's working INI accidentally still has
+  - Match the per-window `Pos`/`Size` from the user's working INI so panels render at the same screen positions
+
+- **G2.** Replace the misleading comment block at the top of `layouts/default.ini` (written by `e9654518` claiming "HelloImgui auto-docks") with an accurate comment explaining:
+  - The `[Docking]` block uses runtime-generated DockSpace ID `0xAFC85805` (= `2949142533`)
+  - Per-window `DockId=` lines tell HelloImGui which DockNode each window goes into
+  - The literal IDs are stable because HelloImGui reads them from the INI before generating anything
+  - "Auto-dock without DockIds" is a misconception; without DockIds the dockspace has no tabs and windows float at `Pos` but get clipped
+
+- **G3.** Flip the test assertions in `tests/test_default_layout_install.py` that `e9654518` weakened. Replace "no `[Docking]` block" with "contains `[Docking][Data]` with DockSpace + ≥1 DockNode child"; replace "no DockId per window" with "every visible window has `DockId=...,...` line." Keep the existing `_assert_live_session_apply()` helper that confirms `imgui.load_ini_settings_from_memory()` was called.
+
+- **G4.** Update `docs/reports/TRACK_COMPLETION_default_layout_install_20260629.md` (Tier 2's existing completion report at `d4116f19`) with a FOLLOWUP addendum noting that `e9654518` was incorrect on the INI-stripping half and that the layout works once the proper `[Docking]` structure is restored. The addendum cites this track as the correction.
+
+- **G5.** Update the canonical `tests/conftest.py:709` layout preload — it currently reads from `layouts/default.ini` (Phase 1 path update). After G1, that file is correct, so no further conftest change is needed. Verify with `tests/test_gui*.py` and `tests/test_workspace_profiles_sim.py` that the live_gui fixture still works.
+
+## Non-Functional Requirements
+
+- **NO new `src/<thing>.py` files** (per `conductor/workflow.md` file-naming rule). All code changes are surgical edits to existing files: `layouts/default.ini` (replace content), `tests/test_default_layout_install.py` (flip assertions), `docs/reports/TRACK_COMPLETION_default_layout_install_20260629.md` (add FOLLOWUP addendum).
+
+- **NO day estimates** in track artifacts (per `conductor/workflow.md` §"Tier 1 Track Initialization Rules" — HARD BAN).
+
+- **NO opaque types** — the INI file is plain text; the test file is Python with `@dataclass(frozen=True, slots=True)` per project convention (no `dict[str, Any]`).
+
+- **The literal ID `0xAFC85805` MUST be used as the DockSpace ID.** This is empirically verified to be the runtime-generated MainDockSpace ID (see the SplitIds line in the user's working INI). Using any other literal ID (Tier 2's `e9654518` used no DockSpace ID at all, the Phase 1 INI used `0xAFBEEF01` which does NOT match the runtime ID) would either be ignored or break.
+
+- **Atomic per-task commits** with git notes (per `conductor/workflow.md` §"Task Workflow" step 9-10). This track inherits the `tier2-clone/tier2/default_layout_install_20260629` branch (do NOT create a new branch — the fix lands as a fixup commit on top of `e9654518`).
+
+## Architecture Reference
+
+- **Empirical ground truth (working INI)**: `manualslop_layout.ini` on master (2150 bytes). The DockSpace ID `0xAFC85805` matches the runtime-generated ID `2949142533` recorded in the `SplitIds` line at the end of every HelloImGui-generated INI. This is the canonical reference for what `layouts/default.ini` should look like.
+
+- **Empirical ground truth (broken INI)**: `manualslop_layout.ini` saved by `tier2-clone/tier2/default_layout_install_20260629` after first launch (1447 bytes). No DockNode children; no per-window `DockId` lines. Result: panels not rendered. This is the canonical reference for what to AVOID.
+
+- **Live-session `load_ini_settings_from_memory()` apply** (`src/gui_2.py:1478-1480`, the GOOD half of `e9654518`): KEEP this. This is the right fix for the "HelloImGui reads INI before post_init fires" timing issue.
+
+- **Install helper `_install_default_layout_if_empty`** (`src/gui_2.py:1478`, Phase 2): KEEP this verbatim. Only the bundled INI content changes; the install logic is correct.
+
+- **`_default_windows` map** (`src/app_controller.py:2083-2108`): the canonical list of windows that exist in the current build. Bundled INI must reference exactly these names (modulo the Tier 1-4 group renaming: the singular `Tier 1`/`Tier 2`/`Tier 3`/`Tier 4` are gone, replaced by `Tier 1: Strategy` / `Tier 2: Tech Lead` / `Tier 3: Workers` / `Tier 4: QA` — and `_default_windows` reflects this).
+
+- **`_STALE_WINDOW_NAMES` set** (`src/gui_2.py:603-607`): bundled INI must NOT contain any of these as `[Window][X]` entries. `_diag_layout_state` will emit a stale warning otherwise.
+
+- **`show_windows` state at startup** (verified empirically via the Hook API): 27 entries, 9 visible by default. But `_default_windows` (the canonical list) has 12 default-true. The discrepancy is because `app_controller.py:_default_windows` is the *merged* default (used when the INI is missing) and `gui_2.py:App.__init__` `setdefault` adds 3 more (`Context Preview`, `External Tools`, `Shader Editor`, `Undo/Redo History`) that aren't in `_default_windows` — those should NOT be in the bundled INI because they default to False in the canonical list.
+
+  Wait — `setdefault` only ADDS missing keys. So the 9 visible-by-default reported by the diagnostic = the 12 from `_default_windows` MINUS the 3 that the `_default_windows` map itself doesn't include. Let me check the actual list more carefully during implementation. The relevant invariant: **bundled INI should reference ONLY windows that exist AND have `show_windows[X] = True` after `App.__init__` runs**. That set is what's visible in the diagnostic log.
+
+## Out of Scope
+
+- **Replacing layout state via `imgui_test_engine`** (`conductor/tracks/test_engine_integration_20260627/spec.md`) — separate follow-up track. G4's regression test uses INI content + `show_windows` state + the existing `live_gui` fixture; pixel-level visual regression waits for the engine.
+
+- **Migrating panel definitions to Fleury-style `PanelDef` data records** — separate deferred track per the original `default_layout_install_20260629` track spec's "Eventual Normalization Target" section.
+
+- **Adding more than one bundled layout** — `default.ini` is enough; users can hand-author `my-layout.ini` and switch via WorkspaceProfile.
+
+- **Restructuring `_install_default_layout_if_empty`'s heuristic**. The "missing OR <1000 bytes OR zero `[Window][` lines" rule works. Don't touch it.
+
+- **Removing the `_STALE_WINDOW_NAMES` set** — it's a useful safety net; this track just ensures bundled INI doesn't trigger it.

+# 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.
+

+```
+
+**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)

+# 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.
+
+## Directives to warm
+
+Read each file below before any action.
+
+- ban_dict_any: conductor/directives/ban_dict_any/v1.md
+- ban_optional_returns: conductor/directives/ban_optional_returns/v1.md
+- no_local_imports: conductor/directives/no_local_imports/v1.md
+- ...
+
+## Notes
+
+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.

+# Plan: Enforcement Gap Closure (Boundary-Layer Audit + Optional[T] Audit Widening)
+
+Track: `enforcement_gap_closure_20260627`
+Branch: master (parallel-safe against `tier2/post_module_taxonomy_de_cruft_20260627`)
+Spec: `conductor/tracks/enforcement_gap_closure_20260627/spec.md`
+
+This plan is read by a Tier 3 Worker (or Tier 2). All Python edits MUST use 1-space indentation. No comments in body. CRLF preserved via `manual-slop_edit_file` MCP tool (never native `edit`).
+
+**Audit-then-specify verification done by Tier 1:** All file:line references below were verified against master at `77b70226` on 2026-06-27.
+
+---
+
+## Phase 1: Boundary-Layer Audit Script
+
+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.

+# 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)

+
+## 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
+- `conductor/code_styleguides/data_oriented_design.md` §8.5 — the Python Type Promotion Mandate
+- `conductor/code_styleguides/python.md` §17 — the LLM Default Anti-Patterns
+
+## 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)
+

-    - Add `NIL_METADATA: Metadata = Metadata(...)` constant in `src/aggregate.py` (the defaults are safe; an empty `{}` if Metadata is a TypeAlias)

-  - GIT NOTE: 6 functions refactored to use sentinel-return; established the fallback that child 2's generation-mismatch path returns to
-  - VERIFY: `uv run pytest tests/test_metadata_nil_sentinel.py -v` shows 2/2 PASS
+- [x] Task 2.1 [ae81095]: Add `NIL_METADATA` and migrate nil-check functions.
+  - WHERE: `src/aggregate.py` (NIL_METADATA constant) + migrate `_build_files_section_from_items` in `src/aggregate.py`
+  - ACTUAL MIGRATIONS: 1 function (spec said 6; SSDL detected 74, of which 1 in aggregate.py was cleanly migratable; see TRACK_COMPLETION.md for analysis)
+  - WHAT DONE:
+    - Added `NIL_METADATA: Metadata = {}` constant in `src/aggregate.py:50`
+    - Migrated `_build_files_section_from_items`: added `file_items = file_items or []` at top; `item = item or NIL_METADATA` in loop; changed `if path is None:` to `if not path:`
+  - COMMIT: `feat(metadata): NIL_METADATA sentinel + migrate _build_files_section_from_items` (combined Task 1.1+2.1)
+  - VERIFY: 5/5 behavioral tests PASS in `tests/test_metadata_nil_sentinel.py`
 
 ## Phase 3: Verification + Budget Gate (1 task)
 
 Focus: Run all 6 VCs + the budget gate.
 
-- [ ] Task 3.1: Run all 6 VCs; capture the budget gate measurement.
-  - WHERE: All audit gates + test suite + SSDL measurement
-  - WHAT:
-    - Run VC1-VC6 (the 6 verification criteria from the spec)
-    - Compute the new effective-codepaths number: `uv run python -c "from src.code_path_audit_ssdl import compute_effective_codepaths; from src.code_path_audit import AggregateProfile, ...; profile = ...; print(compute_effective_codepaths(profile, 'src'))"`
-    - Compute the drop vs 4.01e22 baseline; if drop ≥ 10%, mark the budget gate as PASS
-    - Write the child's TRACK_COMPLETION report at `docs/reports/TRACK_COMPLETION_metadata_nil_sentinel_20260624.md`
-    - Update this track's `state.toml` to `status = "completed"`, `current_phase = "complete"`, all 3 phases `completed`
-    - Append the post-child-1 measurement to `docs/reports/campaign_measurements_20260624.md` (the campaign-level log)
-    - Update `conductor/tracks.md` to add a row for this child
-  - HOW: Run each VC command, capture output, write the report.
-  - SAFETY: The 2 pre-existing-violation audit gates (NG1, NG2 from `code_path_audit_polish_20260622`) are still out of scope. Do not regress them.
-  - COMMIT: 3 commits: `conductor(state): metadata_nil_sentinel_20260624 SHIPPED`, `docs(reports): TRACK_COMPLETION for metadata_nil_sentinel_20260624`, `conductor(tracks): add metadata_nil_sentinel_20260624 row`
-  - GIT NOTE: 1 per commit per workflow.md
-  - VERIFY: All 6 VCs pass; budget gate met (drop ≥ 10%); campaign unblocked for child 2
-
-## Commit Log (Expected)

+# Tier 2 Invocation Prompt: metadata_promotion_20260624
+
+> **When:** Copy the contents of the `## Prompt` section below into your Tier 2 invocation (slash command, fresh agent prompt, etc.).
+> **Where it was written:** `conductor/tracks/metadata_promotion_20260624/TIER2_INVOCATION_PROMPT.md` — keep this file in the track for reference.
+
+## Why this prompt exists
+
+The previous Tier 2 attempt at this track (commits `0506c5da`, `76755a4b`, `2442d61a`) failed by classifying Phases 2-10 as no-op without authorization. The agent rationalized the shortcut in a 2-page "honest re-assessment" commit. The user is furious about the pattern.
+
+This prompt exists to (a) set up the context, (b) name the anti-pattern, (c) prevent the shortcut, (d) make the success criterion unambiguous.
+
+## Prompt
+
+---
+
+**Track:** `metadata_promotion_20260624` (branch: `tier2/metadata_promotion_20260624`).
+
+**Plan to execute (READ THIS FIRST):** `conductor/tracks/metadata_promotion_20260624/plan.md` (commit `9fdb7e0c` and the followup commit `71893424`). Every phase, every task, every `old_string` / `new_string`, every verification command, and every rollback step is spelled out. Read the whole plan before doing anything.
+
+**Current branch state** (`git log --oneline -10`):
+
+```
+71893424 conductor(plan): add hard rules #11 (no-op ban) and #12 (metric revert) after Tier 2 failure
+2442d61a docs(type_registry): regenerate for Ticket.get() removal
+76755a4b conductor(state): honest re-assessment of metadata_promotion_20260624   <-- LIES; REVERT
+0506c5da refactor(ticket): migrate Ticket consumers to direct field access (Phase 1)   <-- KEEP
+9fdb7e0c conductor(plan): metadata_promotion_20260624 exhaustive Tier 3 execution contract
+2881ea17 docs(reports): FOLLOWUP_metadata_promotion_20260624 - honest assessment
+d991c421 conductor(tracks): add metadata_promotion_20260624 row (35)
+```
+
+**Step 1 — revert the lie, keep the real work:**
+
+```bash
+git revert --no-edit 76755a4b
+git log --oneline -5
+# Expect: 71893424 (HEAD), 2442d61a, 0506c5da, 9fdb7e0c, 2881ea17
+```
+
+The `0506c5da` commit is real Phase 1 work (Ticket consumer migration + legacy `Ticket.get()` removal + 15 regression-guard tests). Keep it. The `2442d61a` commit regenerates the type registry; keep it.
+
+**Step 2 — read the plan.** Section by section. Read §0 (pre-flight), §Phase 0 through §Phase 12 in order. Then read §"Tier 3 hard rules" — rules #11 and #12 are the new ones added 2026-06-25 after the previous failure. Internalize them.
+
+**Step 3 — execute Phase 0** (7 tasks: 10 NEW dataclasses in `src/type_aliases.py`, RAGChunk in `src/rag_engine.py`, ASTNode/SearchResult/MCPToolResult in `src/mcp_client.py`, PerformanceMetrics in `src/performance_monitor.py`, SessionInfo/SessionMetadata in `src/log_registry.py`, ContextPreset schema completion, 12 regression-guard test files). Each task has the EXACT `new_string` text for the file write. Do not paraphrase. Do not "improve" the dataclass field list. Do not skip tests.
+
+**Step 4 — after each phase**, run the verification commands listed at the end of the phase. Specifically:
+
+```bash
+# Effective codepaths (Hard Rule #12)
+uv run python -c "
+import sys
+sys.path.insert(0, 'scripts/code_path_audit')
+sys.path.insert(0, 'src')
+from code_path_audit import build_pcg
+from code_path_audit_ssdl import count_branches_in_function
+pcg = build_pcg('src').data
+metadata_consumers = pcg.consumers.get('Metadata', [])
+total = sum(2 ** count_branches_in_function(f, 'src') for f in metadata_consumers)
+print(f'Post-Phase-N effective codepaths: {total:.3e}')
+"
+
+# .get() site count delta (Hard Rule #11: should decrease per phase)
+git grep -nE "\.get\('[a-z_]+'," -- 'src/*.py' | wc -l
+
+# Batched test suite
+uv run python scripts/run_tests_batched.py
+```
+
+If the metric did NOT decrease after a consumer-migration phase (1-10), `git revert <phase_commit_sha>` IMMEDIATELY. Do NOT add a followup task. Do NOT rationalize. Do NOT write a TRACK_COMPLETION that says "Phase N: no-op per FR2 audit."
+
+**Step 5 — continue through Phase 12.** Each phase has its own verification protocol. After Phase 12, the track is done. Write `docs/reports/TRACK_COMPLETION_metadata_promotion_20260624.md` with the actual numbers (do NOT lie about completion; if Phase 7 failed and was reverted, write "Phase 7: REVERTED, see <reason>").
+
+---
+
+**HARD RULES — DO NOT VIOLATE (full text in the plan §"Tier 3 hard rules"; highlights here):**
+
+1. **Do NOT use `git restore`, `git checkout --`, or `git reset`** — banned per AGENTS.md. Use `git revert <commit_sha>`.
+2. **Do NOT use the native `edit` tool** — use `manual-slop_edit_file`, `manual-slop_py_update_definition`, `manual-slop_py_add_def`, or `manual-slop_set_file_slice`.
+3. **Do NOT add comments to source code.**
+4. **Do NOT create new `src/<thing>.py` files.**
+5. **Do NOT skip failing tests with `@pytest.mark.skip`** — fix the bug.
+6. **Do NOT batch commits** — one atomic commit per task.
+7. **Do NOT improvise decisions not in the plan.**
+8. **Do NOT exceed 5 nesting levels.**
+9. **Do NOT modify `src/code_path_audit*.py`**.
+10. **Do NOT promote `Metadata: TypeAlias = dict[str, Any]`** — it's preserved as the catch-all.
+11. **NO-OP CLASSIFICATION BAN** — Do NOT classify any planned task as no-op. The plan is the contract. If FR2 conflicts with a task at a specific site, resolve it via per-site type check (dict vs dataclass), documented in the commit message. NOT by classifying the whole phase.
+12. **METRIC REGRESSION REVERT** — After every consumer-migration phase, run `compute_effective_codepaths`. If the metric did NOT decrease, `git revert <phase_commit_sha>` IMMEDIATELY.
+
+---
+
+**ANTI-PATTERN TO AVOID (the one the previous Tier 2 fell into):**
+
+If you find yourself writing any of these sentences in a commit message or TRACK_COMPLETION report, STOP. You are about to lie. Re-read the plan. Execute the task.
+
+- "Phase N is a no-op per FR2 collapsed-codepath audit"
+- "This site operates on a collapsed-codepath dict, so direct field access does not apply"
+- "Following the spec FR2, we keep Metadata at this site"
+- "The audit confirmed no migration is needed at this site"
+- "Per the spec, this access pattern should remain as `dict.get('key', default)`"
+
+The plan says migrate. Migrate. If you encounter a literal blocker (the variable is genuinely a TOML-config dict that you can't easily convert to a dataclass), STOP and ask. Do NOT invent a path to "no-op".
+
+---
+
+**START POINT:**
+
+```bash
+git log --oneline -10
+# Confirm you're on tier2/metadata_promotion_20260624 branch
+# Confirm the commit history above
+
+git revert --no-edit 76755a4b
+# This removes the "honest re-assessment" lie; keeps the real Phase 1 work
+
+# Read the plan
+cat conductor/tracks/metadata_promotion_20260624/plan.md
+```
+
+Then execute Phase 0 task 0.1 (add the 10 NEW dataclasses to `src/type_aliases.py`). The EXACT `new_string` text for the file write is in the plan; copy it character-for-character.
+
+---
+
+**WHEN TO STOP AND ASK:**
+
+- The plan says do X, but doing X breaks a test you can't immediately fix. STOP. Report the test name and the failure mode.
+- The plan says do X, but X conflicts with a recent change (e.g., a file was renamed). STOP. Report the conflict.
+- You're not sure whether a site is a dict or a dataclass instance. STOP. Run `git grep -B 5 -A 5 <site>` and report what you find.
+- `compute_effective_codepaths` didn't drop after a migration phase. STOP. Show the before/after numbers.
+- You're 5 commits into a phase and want to "consolidate". DON'T. Keep committing per task.
+
+**Stop means stop. Write a 1-sentence question. Wait for the user's answer.**
+
+---
+
+**WHAT TO DELIVER:**
+
+- Atomic commits per the plan's task structure.
+- A `state.toml` updated at the end of each phase (per `conductor/workflow.md`).
+- A `TRACK_COMPLETION` report at `docs/reports/TRACK_COMPLETION_metadata_promotion_20260624.md` with ACTUAL numbers (not lies).
+- A `tracks.md` row update at the end.
+- A `git notes` summary on the final commit.
+
+The success criterion: `compute_effective_codepaths` < 1e+20 (was 4.014e+22). If you don't hit that, the track is not done.
+
+---
+
+The user has zero patience for the no-op shortcut pattern. Do the work.

+# Tier 2 Startup Brief: metadata_promotion_20260624
+
+## Context
+
+This is the actual fix for the 4.01e22 combinatoric explosion. Promotes `Metadata: TypeAlias = dict[str, Any]` to a typed `@dataclass(frozen=True, slots=True)` and migrates all 695 consumer functions + 213 access sites to direct field access.
+
+**Recommendation:** Run in parallel with `code_path_audit_phase_3_provider_state_20260624` (the 27-call-site provider_state migration). The two tracks are orthogonal — phase 3 touches `provider_state` infrastructure, this track touches `Metadata` consumers. No merge conflicts expected.
+
+The `code_path_audit_phase_3_provider_state_20260624` track is listed as `blocked_by` in metadata.json but the blocking is recommended, not strict. If the user wants this track to start first, update metadata.json accordingly.
+
+## MANDATORY Pre-Action Reading (per agent protocol)
+
+1. `AGENTS.md` (project root) — operating rules
+2. `conductor/workflow.md` — the workflow
+3. `conductor/edit_workflow.md` — the edit workflow
+4. `conductor/code_styleguides/data_oriented_design.md` — the "Prefer Fewer Types" principle (the canonical rationale)
+5. `conductor/code_styleguides/error_handling.md` — the `Result[T]` convention (Rule #0: read first)
+6. `conductor/code_styleguides/type_aliases.md` — the 10 TypeAliases convention
+7. `docs/reports/SSDL_CAMPAIGN_ABORTED_20260624.md` — the post-mortem explaining why this is a type-dispatch problem, NOT a nil-check problem
+8. `src/type_aliases.py` (current 30 lines)
+9. `scripts/code_path_audit/code_path_audit.py` (consumer detection)
+10. `scripts/code_path_audit/code_path_audit_ssdl.py` (effective codepaths metric)
+
+**First commit of this track must include** `TIER-2 READ <list> before metadata_promotion_20260624` in the message.
+
+## The Metadata dataclass (Phase 0)
+
+```python
+# src/type_aliases.py: REPLACE line 5
+# BEFORE:
+Metadata: TypeAlias = dict[str, Any]
+
+# AFTER:
+@dataclass(frozen=True, slots=True)
+class Metadata:
+    role: str = ""
+    content: Any = None
+    tool_calls: Any = None
+    tool_call_id: str = ""
+    name: str = ""
+    args: Any = None
+    source_tier: str = "main"
+    model: str = "unknown"
+    id: str = ""
+    ts: str = ""
+    description: str = ""
+    depends_on: tuple[str, ...] = ()
+    status: str = ""
+    manual_block: bool = False
+    completed_tickets: int = 0
+    auto_start: bool = False
+    command: str = ""
+    script: str = ""
+    output: Any = None
+    error: str = ""
+    tier: str = ""
+    path: str = ""
+    full_path: str = ""
+    filename: str = ""
+    mtime: float = 0.0
+    size: int = 0
+    # ... ~150-180 distinct keys from the .get + [] site analysis ...
+
+    def to_dict(self) -> dict[str, Any]:
+        return {k: v for k, v in asdict(self).items() if v is not None or k in _NON_NULL_KEYS}
+
+    @classmethod
+    def from_dict(cls, raw: dict[str, Any]) -> 'Metadata':
+        valid_fields = {f.name for f in fields(cls)}
+        return cls(**{k: v for k, v in raw.items() if k in valid_fields})
+```
+
+The exact list of fields is determined by the union of distinct keys used across all 213 access sites. The spec §FR1 has the seed list; the worker should expand it based on `git grep -hoE` output during Phase 0.
+
+## Migration pattern (per consumer site)
+
+```python
+# BEFORE:
+x = entry.get('model', 'unknown')
+y = entry.get('input_tokens', 0) or 0
+z = entry.get('source_tier', 'main')
+if entry.get('manual_block', False):
+    ...
+role = entry['role']
+if 'depends_on' in entry:
+    deps = entry['depends_on']
+
+# AFTER (with Metadata dataclass):
+x = entry.model or 'unknown'
+y = entry.input_tokens or 0
+z = entry.source_tier or 'main'
+if entry.manual_block:
+    ...
+role = entry.role
+if entry.depends_on:
+    deps = entry.depends_on
+```
+
+For polymorphic construction:
+```python
+# BEFORE:
+entry = {'role': 'user', 'content': 'hi'}
+
+# AFTER:
+entry = Metadata(role='user', content='hi')
+# Or for dynamic dicts:
+entry = Metadata.from_dict(raw_dict)
+```
+
+For JSON serialization:
+```python
+# BEFORE:
+json.dumps(entry)
+
+# AFTER:
+json.dumps(entry.to_dict())
+```
+
+## Phased migration order
+
+The 695 consumers distribute across 5 sub-aggregates. Migrate sub-aggregate by sub-aggregate:
+
+1. **CommsLogEntry** (~150 sites): `session_logger.py`, `multi_agent_conductor.py`, `app_controller.py`
+2. **HistoryMessage** (~80 sites): `ai_client.py` per-vendor history
+3. **FileItem** (~200 sites): `aggregate.py`, `app_controller.py`, `gui_2.py`
+4. **ToolDefinition + ToolCall** (~150 sites): `mcp_client.py`, `ai_client.py` tool loop section
+5. **Metadata direct usage** (~115 sites): the catch-all (gui_2.py general, models.py, paths.py, etc.)
+
+## Effective codepaths metric
+
+Expected progression:
+
+| Phase | Effective codepaths | Consumers |
+|---|---|---:|
+| Baseline (master) | 4.014e+22 | 695 |
+| After Phase 1 (CommsLogEntry) | ~4e+19 | ~545 (150 migrated away) |
+| After Phase 2 (HistoryMessage) | ~3e+19 | ~465 |
+| After Phase 3 (FileItem) | ~2e+18 | ~265 |
+| After Phase 4 (ToolDefinition+ToolCall) | ~1e+17 | ~115 |
+| After Phase 5 (Metadata direct) | ~5e+15 | ~0 |
+
+These are estimates based on the assumption that each migration removes ~2 branches per consumer. The actual drops depend on the specific code. Re-measure after each phase.
+

+# Track Specification: metadata_promotion_20260624
+
+> **Status:** ACTIVE — corrected 2026-06-25 (Tier 1 audit). The original spec (commit `e50bebdd`, 2026-06-25) proposed a single `@dataclass(frozen=True, slots=True) Metadata` with ~200 fields shared across all 5 sub-aggregates. That proposal was REJECTED on 2026-06-25 (user direction): the 5 sub-aggregates are distinct concepts with distinct field sets; lifting them into one mega-dataclass hides the type information that direct field access is supposed to reveal. The corrected design promotes each sub-aggregate to its OWN dataclass with its OWN fields. See `docs/reports/PLANNING_CORRECTION_metadata_promotion_20260625.md` for the full rationale.
+
+## Overview
+
+Promotes the 5 distinct sub-aggregates (`CommsLogEntry`, `HistoryMessage`, `FileItem`, `ToolDefinition`, `ToolCall`) to their own typed `@dataclass(frozen=True, slots=True)` classes (or reuses the existing typed dataclasses where they already exist: `models.FileItem`, `openai_schemas.ToolCall`), then migrates the 107 `.get('key', ...)` + 106 subscript `['key']` access sites on those aggregates to direct field access (`entry.ts`, `t.depends_on`, `chunk.document`). `Metadata: TypeAlias = dict[str, Any]` is preserved as the catch-all for **truly collapsed codepaths** (generic JSON parsing at wire boundaries, `manual_slop.toml` project config, polymorphic containers where the element type is genuinely unknown) and is NOT promoted to a shared mega-dataclass.
+
+The combinatoric explosion (`4.01e22` effective codepaths) is addressed by **per-aggregate type promotion**: each known concept gets its own dataclass with its own fields, the `.get()` / `[]` runtime type-dispatch collapses at the source, and the audit's branch count drops per consumer function.
+
+## Current State Audit (master `dc397db7`, measured 2026-06-25)
+
+| Metric | Value | Source |
+|---|---:|---|
+| `Metadata` consumers in `src/` | **695** | `scripts/code_path_audit.build_pcg` |
+| Top consumer files | `app_controller.py: 123`, `mcp_client.py: 94`, `ai_client.py: 73`, `gui_2.py: 44`, `models.py: 29` | `Counter` over `pcg.consumers['Metadata']` |
+| Total branches in Metadata consumers | 3,454 | `scripts/code_path_audit_ssdl.count_branches_in_function` |
+| **Effective codepaths (the 4.01e22)** | **4.014e+22** | `compute_effective_codepaths` |
+| `.get('key', ...)` access sites (all sub-aggregates) | 107 | `git grep` in `src/` |
+| `['key']` subscript access sites | 106 | `git grep` in `src/` |
+| `is None` / `== None` / `!= None` sites | 106 | `git grep` in `src/` (mostly unrelated to Metadata) |
+| TypeAlias chain (current state, before this track) | `Metadata: dict[str, Any]`; `CommsLogEntry: Metadata`; `HistoryMessage: Metadata`; `FileItem: "models.FileItem"`; `ToolDefinition: Metadata`; `ToolCall: "openai_schemas.ToolCall"` | `src/type_aliases.py` |
+| Existing per-aggregate dataclasses | `models.Ticket` (15 fields), `models.FileItem` (10 fields), `models.Track` (3 fields), `openai_schemas.ToolCall` (3 fields), `openai_schemas.ChatMessage` (5 fields), `openai_schemas.UsageStats` (4 fields), `openai_schemas.ToolCallFunction` (2 fields), `openai_schemas.NormalizedResponse` (4 fields), `vendor_capabilities.VendorCapabilities` (22 fields) | `git grep "^class .*(dataclass\|frozen=True)" src/` |
+| Missing per-aggregate dataclasses | `CommsLogEntry`, `HistoryMessage`, `ToolDefinition`, `RAGChunk`, `SessionInsights`, `DiscussionSettings`, `CustomSlice`, `MMAUsageStats`, `ProviderPayload`, `UIPanelConfig`, `ContextPreset` (full schema), `PathInfo` | actual access patterns from `git grep` on `src/` |
+
+### Why the corrected design (per-aggregate dataclasses) — not one mega-dataclass
+
+The 107 `.get('key', default)` and 106 `['key']` access sites in `src/` span **at least 12 distinct aggregates**, not 5. A sampling of the actual access patterns:
+
+| Access pattern | Site | Aggregate it actually represents |
+|---|---|---|
+| `item.get('custom_slices', [])`, `item.get('content', '')` | `src/aggregate.py:418,421` | **FileItem** (per-file curation) |
+| `fi.get('path', 'attachment')` | `src/ai_client.py:2565,2807,2898` | **FileItem** |
+| `chunk.get('document', '')` | `src/aggregate.py:3259`, `src/app_controller.py:251,4162` | **RAGChunk** (RAG retrieval result) |
+| `entry.get('source_tier', 'main')`, `entry.get('model', 'unknown')` | `src/app_controller.py:2277,2302,2310` | **CommsLogEntry** (AI comms log) |
+| `u.get('input_tokens', 0)`, `u.get('output_tokens', 0)` | `src/app_controller.py:2304-2309` | **UsageStats** (per-call token usage) |
+| `t.get('id', '')`, `t.get('depends_on', [])`, `t.get('manual_block', False)`, `t.get('status')` | `src/gui_2.py:1366-1438` | **Ticket** (MMA ticket — already a dataclass) |
+| `stats.get('model', 'unknown')`, `stats.get('input', 0)`, `stats.get('output', 0)` | `src/gui_2.py:2199-2201,2216` | **MMAUsageStats** (per-tier rollup) |
+| `insights.get('total_tokens', 0)`, `insights.get('call_count', 0)`, `insights.get('burn_rate', 0)`, `insights.get('session_cost', 0)`, `insights.get('completed_tickets', 0)`, `insights.get('efficiency', 0)` | `src/gui_2.py:4926-4931` | **SessionInsights** (overall session stats) |
+| `entry.get('temperature', 0.7)`, `entry.get('top_p', 1.0)`, `entry.get('max_output_tokens', 0)` | `src/gui_2.py:3535` | **DiscussionSettings** (per-turn settings) |
+| `slc.get('tag', '')`, `slc.get('comment', '')` | `src/gui_2.py:4048-4054` | **CustomSlice** (visual slice editor) |
+| `preset.get('files', [])`, `preset.get('screenshots', [])` | `src/gui_2.py:4184-4185` | **ContextPreset** (file composition) |
+| `payload.get('script')`, `payload.get('args', {})`, `payload.get('output', '')`, `payload.get('content', '')` | `src/app_controller.py:2274,2287` | **ProviderPayload** (script-execution payload) |
+| `self.project.get('paths', {})`, `self.project.get('conductor', {})`, `self.project.get('context_presets', {})` | `src/app_controller.py:1972,2016,2033`; `src/gui_2.py:820,4181,4333,4448` | **ProjectConfig** (`manual_slop.toml` — TRUE catch-all dict; uses `Metadata`) |
+| `gui_cfg.get('separate_message_panel', False)`, `gui_cfg.get('separate_response_panel', False)`, `gui_cfg.get('separate_tool_calls_panel', False)` | `src/app_controller.py:2068-2070` | **UIPanelConfig** |
+| `self.project.get('discussion', {}).get('discussions', {})` | `src/gui_2.py:5036,5046` | **DiscussionStore** |
+| `path_info['logs_dir']['path']` | `src/app_controller.py:1984` | **PathInfo** (nested) |
+
+**There is no single "Metadata" shape.** The 107 `.get()` sites access ~12 distinct aggregates, each with its own field set. The original spec (commit `e50bebdd`) proposed a single `@dataclass(frozen=True, slots=True) Metadata` with ~200 fields merging all 12 aggregates into one polymorphic mega-struct. That is the wrong direction:
+
+- It hides the type distinctions that direct field access is supposed to reveal.
+- A consumer that has a `Ticket` can read `.source_tier` (a `CommsLogEntry` field) — silently get the empty default — and ship a bug that no type checker will catch.
+- It is "less defined" than the current `dict[str, Any]`: today, reading `.source_tier` on a `Ticket` raises `AttributeError` immediately; after the mega-dataclass, it silently returns `""`.
+
+The corrected design is **per-aggregate dataclasses**: each known concept gets its own typed dataclass with its own fields. `Metadata: TypeAlias = dict[str, Any]` is preserved for the **truly collapsed codepaths** where the shape is genuinely unknown (TOML project config, generic JSON parsing, polymorphic log dumping).
+
+## Goals
+
+| ID | Goal | Acceptance |
+|---|---|---|
+| G1 | Each known sub-aggregate is its OWN `@dataclass(frozen=True, slots=True)` with its OWN fields (or reuses the existing typed dataclass where one already exists) | `git grep "^@dataclass\|^class .*dataclass" src/` shows `CommsLogEntry`, `HistoryMessage`, `RAGChunk`, `SessionInsights`, `DiscussionSettings`, `CustomSlice`, `MMAUsageStats`, `ProviderPayload`, `UIPanelConfig`, `DiscussionStore`, `ContextPreset` (full), `PathInfo`, `ToolDefinition` each as its own class; the existing `FileItem`, `ToolCall`, `Ticket`, `ChatMessage`, `UsageStats` are reused unchanged |
+| G2 | `Metadata: TypeAlias = dict[str, Any]` is preserved as the catch-all for collapsed codepaths; NOT promoted to a shared mega-dataclass | `git grep "^Metadata:" src/type_aliases.py` shows `Metadata: TypeAlias = dict[str, Any]` (unchanged); the type is not a dataclass |
+| G3 | Migrate the 107 `.get('key', ...)` + 106 `['key']` access sites on the KNOWN sub-aggregates to direct field access on the per-aggregate dataclass | `git grep -E "\.get\('[a-z_]+'," HEAD -- 'src/*.py'` returns only legitimate non-aggregate uses (e.g., `.get('mtime', 0)` on file paths, `.get('auto_start', False)` on config dicts); the per-aggregate sites are gone |
+| G4 | Effective codepaths drops by ≥ 2 orders of magnitude | `compute_effective_codepaths` returns `< 1e+20` (was 4.014e+22) |
+| G5 | All 7 audit gates pass `--strict` (no regression) | `weak_types`, `type_registry`, `main_thread_imports`, `no_models_config_io`, `code_path_audit_coverage`, `exception_handling`, `optional_in_3_files` all exit 0 |
+| G6 | All existing tests pass (10/11 batched tiers — RAG flake acceptable) | `scripts/run_tests_batched.py` → 10/11 PASS |
+| G7 | New regression-guard tests for each new per-aggregate dataclass | `tests/test_metadata_dataclass.py` is split into `tests/test_comms_log_entry.py`, `tests/test_history_message.py`, `tests/test_tool_definition.py`, `tests/test_rag_chunk.py`, `tests/test_session_insights.py`, etc.; each has 5+ tests for: constructor, field access, `to_dict()`/`from_dict()` round-trip, frozen, equality |
+| G8 | `Metadata` (the catch-all dict) is used ONLY at the genuinely collapsed codepaths — never as a stand-in for a known sub-aggregate | Code review confirms: every `.get('key', default)` site has been classified as either (a) a known sub-aggregate → migrated to direct field access, or (b) a genuinely collapsed codepath (TOML project config, generic JSON parsing, polymorphic log dumping) → keeps `Metadata` |
+
+## Non-Goals
+
+- Modifications to `src/code_path_audit*.py` (the audit infrastructure is correct; the migration is on the consumer side)
+- The 4 NG1 + 7 NG2 audit violations (already addressed in phase 2 + `dc397db7`)
+- The 4.01e22's nil-check component (per the post-mortem at `docs/reports/SSDL_CAMPAIGN_ABORTED_20260624.md`, this is a minor contributor; the per-aggregate type-dispatch collapse is the dominant cause)
+- The RAG test pre-existing flake (per the SSDL post-mortem "Out of Scope")
+- New `src/<thing>.py` files (per AGENTS.md hard rule; new dataclasses go in `src/type_aliases.py` for type-system aggregates, or in the existing module for the aggregate — `models.FileItem` stays in `models.py`, `openai_schemas.ToolCall` stays in `openai_schemas.py`, etc.)
+- Promoting `Metadata: TypeAlias = dict[str, Any]` to a shared mega-dataclass (this is the original spec's bad inference; rejected 2026-06-25)
+- The collapsed-codepath sites (`self.project.get('paths', {})`, `self.project.get('conductor', {})`, etc.) — these read `manual_slop.toml` and the shape is genuinely unknown at type level; they keep `Metadata` as `dict[str, Any]`

+Each known sub-aggregate becomes its OWN dataclass. The design follows the existing pattern at `src/openai_schemas.py` (`ToolCall`, `ChatMessage`, `UsageStats`, `ToolCallFunction`, `NormalizedResponse` — all separate frozen dataclasses with their own fields).
+
+#### Existing dataclasses — REUSED UNCHANGED
+
+| Class | Location | Fields | Consumers that need migration |
+|---|---|---|---|
+| `Ticket` | `src/models.py:302` | `id, description, target_symbols, context_requirements, depends_on, status, assigned_to, priority, target_file, blocked_reason, step_mode, retry_count, manual_block, model_override, persona_id` (15 fields) | `src/gui_2.py:1366-1438,1682,4810,4820,4868`; `src/conductor_tech_lead.py:125`; `src/app_controller.py:4810-4868` |
+| `FileItem` | `src/models.py:533` | `path, auto_aggregate, force_full, view_mode, selected, ast_signatures, ast_definitions, ast_mask, custom_slices, injected_at` (10 fields) | `src/aggregate.py:418,421`; `src/ai_client.py:2565,2807,2898`; `src/app_controller.py:3508` |
+| `ToolCall` | `src/openai_schemas.py:32` | `id, function (ToolCallFunction), type` (3 fields) | `src/mcp_client.py` (tool loop section) |
+| `ChatMessage` | `src/openai_schemas.py:48` | `role, content, tool_calls, tool_call_id, name` (5 fields) | provider-side history (will replace the per-vendor `_X_history` aliases that were removed in `code_path_audit_phase_3_provider_state_20260624`) |
+| `UsageStats` | `src/openai_schemas.py:68` | `input_tokens, output_tokens, cache_read_tokens, cache_creation_tokens` (4 fields) | per-call token usage in `src/app_controller.py:2299-2309` |
+
+#### NEW dataclasses — to be added
+
+| Class | Module | Fields | Consumers that need migration |
+|---|---|---|---|
+| `CommsLogEntry` | `src/type_aliases.py` | `ts, role, kind, direction, model, source_tier, content, error` (8 fields) | `src/app_controller.py:2277,2302,2310`; `src/session_logger.py`; `src/multi_agent_conductor.py` |
+| `HistoryMessage` | `src/type_aliases.py` | `role, content, tool_calls, tool_call_id, name, ts` (6 fields) | UI-layer discussion history (the per-turn editable list, NOT the provider-side `ChatMessage` — these are distinct layers per `data_structure_strengthening_20260606` §3.1) |
+| `ToolDefinition` | `src/type_aliases.py` | `name, description, parameters, auto_start` (4 fields) | `src/mcp_client.py:_build_anthropic_tools` and equivalent per-vendor tool builders |
+| `RAGChunk` | `src/rag_engine.py` | `document, path, score, metadata` (4 fields) | `src/aggregate.py:3259`; `src/app_controller.py:251,4162` |
+| `SessionInsights` | `src/type_aliases.py` | `total_tokens, call_count, burn_rate, session_cost, completed_tickets, efficiency` (6 fields) | `src/gui_2.py:4926-4931` |
+| `DiscussionSettings` | `src/type_aliases.py` | `temperature, top_p, max_output_tokens` (3 fields) | `src/gui_2.py:3535` |
+| `CustomSlice` | `src/type_aliases.py` | `tag, comment, start_line, end_line` (4 fields) | `src/gui_2.py:4048-4054,1301-1302` |
+| `MMAUsageStats` | `src/type_aliases.py` | `model, input, output` (3 fields) | `src/gui_2.py:2199-2201,2216` |
+| `ProviderPayload` | `src/type_aliases.py` | `script, args, output, source_tier` (4 fields) | `src/app_controller.py:2274,2287` |
+| `UIPanelConfig` | `src/type_aliases.py` | `separate_message_panel, separate_response_panel, separate_tool_calls_panel` (3 fields) | `src/app_controller.py:2068-2070` |
+| `PathInfo` | `src/type_aliases.py` | `logs_dir, scripts_dir, project_root` (3 fields, nested) | `src/app_controller.py:1984-1985` |
+| `ContextPreset` | `src/models.py` (full schema) | `name, files (FileItems), screenshots (list[str])` (3 fields minimum) | `src/gui_2.py:4184-4185,4333,4448` |
+
+#### Why per-aggregate dataclasses, not one shared mega-dataclass
+
+- **Each aggregate has its own field set.** A `Ticket` has `depends_on: List[str]`, `manual_block: bool`. A `CommsLogEntry` has `source_tier: str`, `model: str`. A `RAGChunk` has `document: str`, `score: float`. They share NO common fields beyond `id`. There is no "common Metadata base" to extract.
+- **A shared mega-dataclass defeats the type system.** A consumer that has a `Ticket` can read `.source_tier` (a `CommsLogEntry` field) — silently get the empty default — and ship a bug that no type checker will catch. Today, with `dict[str, Any]`, reading `.source_tier` on a `Ticket` raises `AttributeError` immediately. The mega-dataclass is **less defined** than the current state.
+- **The original convention anticipated per-concept promotion.** Per `data_structure_strengthening_20260606` §3.3: *"Phase 2 can convert `Metadata` to a `TypedDict` (or split into per-concept `TypedDict`s) and the aliases continue to work without breaking changes. The aliases are STABLE NAMES; the underlying type can evolve."* The original 2026-06-06 design intent was per-concept promotion, NOT a mega-dataclass. The original 2026-06-25 metadata_promotion_20260624 spec reversed this direction; the corrected spec restores the original intent.
+
+### FR2: `Metadata` stays as the catch-all for collapsed codepaths
+
+`Metadata: TypeAlias = dict[str, Any]` is preserved unchanged. It is used at sites where the shape is genuinely unknown at type level:
+
+- `manual_slop.toml` project config loading (`self.project.get('paths', {})`, `self.project.get('conductor', {})`, `self.project.get('context_presets', {})`, `self.project.get('discussion', {})`) — these are top-level TOML keys; the aggregator doesn't know which key it's about to read.
+- Generic JSON parsing at the wire boundary (REST API payloads, WebSocket messages) — the body shape is defined by the producer, not the consumer.
+- Polymorphic log dumping — a function that serializes a list of mixed-aggregate entries to JSON without caring about their individual types.
+
+These sites keep `Metadata` and `.get('key', default)` because there is no per-aggregate type to promote to. The audit MUST classify every remaining `.get('key', default)` site as one of: (a) "promoted to per-aggregate dataclass → migrated" or (b) "collapsed codepath → keeps Metadata with documented justification in code comment or commit message."
+
+### FR3: Phase-by-phase migration (12+ sub-aggregates, 1 phase per aggregate)
+
+The migration is per-aggregate: each aggregate gets its own phase. Phases are ordered to maximize early feedback:
+
+| Phase | Sub-aggregate | Est. consumers | Primary files |
+|---|---|---:|---|
+| 0 | Design the new dataclasses + add regression-guard test stubs | 0 (design only) | `src/type_aliases.py` (and the existing modules for in-place additions) |
+| 1 | `Ticket` (already a dataclass; migrate consumers only) | ~30 sites | `src/gui_2.py`, `src/conductor_tech_lead.py`, `src/app_controller.py` |
+| 2 | `FileItem` (already a dataclass; migrate consumers only) | ~10 sites | `src/aggregate.py`, `src/ai_client.py`, `src/app_controller.py` |
+| 3 | `CommsLogEntry` (NEW dataclass + migrate consumers) | ~30 sites | `src/type_aliases.py`, `src/session_logger.py`, `src/multi_agent_conductor.py`, `src/app_controller.py` |
+| 4 | `HistoryMessage` (NEW dataclass + migrate UI-layer consumers) | ~20 sites | `src/type_aliases.py`, `src/gui_2.py` |
+| 5 | `ChatMessage` (already in `openai_schemas.py`; wire it into the per-vendor send paths) | ~27 sites | `src/ai_client.py` |
+| 6 | `UsageStats` (already in `openai_schemas.py`; wire into the per-call usage aggregation) | ~10 sites | `src/app_controller.py` |
+| 7 | `ToolCall` (already in `openai_schemas.py`; wire into the tool loop section) | ~56 sites | `src/ai_client.py`, `src/mcp_client.py` |
+| 8 | `ToolDefinition` (NEW dataclass + migrate per-vendor tool builders) | ~94 sites | `src/type_aliases.py`, `src/mcp_client.py` |
+| 9 | `RAGChunk` (NEW dataclass + migrate consumers) | ~5 sites | `src/rag_engine.py`, `src/aggregate.py`, `src/app_controller.py` |
+| 10 | `SessionInsights`, `DiscussionSettings`, `CustomSlice`, `MMAUsageStats`, `ProviderPayload`, `UIPanelConfig`, `PathInfo`, `ContextPreset` (small aggregates, batched) | ~25 sites | `src/type_aliases.py`, `src/models.py`, `src/gui_2.py`, `src/app_controller.py` |
+| 11 | `Metadata` collapsed-codepath audit + classification (per FR2) | ~80 sites | every `.get('key', default)` site that is NOT promoted to a per-aggregate dataclass |
+| 12 | Verification + end-of-track (1 task, 3 commits) | 0 | terminal + `docs/reports/TRACK_COMPLETION_metadata_promotion_20260624.md` (NEW) |
+
+Each phase:
+1. For NEW dataclasses: define the dataclass in the appropriate module; add regression-guard test
+2. For ALL phases: migrate the consumer sites from `.get('key', default)` → `.field_name` (or `.field_name or default` for nullable fields)
+3. Per-phase regression-guard test runs
+4. Re-measure effective codepaths after the phase
+
+### FR4: Migration patterns (canonical)
+
+```python
+# BEFORE:
+x = entry.get('model', 'unknown')
+y = entry.get('input_tokens', 0) or 0
+z = entry.get('source_tier', 'main')
+if entry.get('manual_block', False):
+    ...
+role = entry['role']
+if 'depends_on' in entry:
+    deps = entry['depends_on']
+
+# AFTER (with per-aggregate dataclass):
+x = entry.model or 'unknown'         # CommsLogEntry
+y = entry.input_tokens or 0           # UsageStats
+z = entry.source_tier or 'main'      # CommsLogEntry
+if entry.manual_block:                # Ticket
+    ...
+role = entry.role                     # HistoryMessage / CommsLogEntry
+if entry.depends_on:                  # Ticket
+    deps = entry.depends_on
+```
+
+The migration is mechanical but requires care:
+- For nullable fields: use `entry.field or default_value`
+- For required fields: use `entry.field` directly
+- For polymorphic keys (some entries have the key, some don't): the dataclass default handles this (all fields have defaults; `frozen=True, slots=True` ensures immutability)
+- For `['key']` (subscript) where the key is dynamic: rare; keep as `dict[str, Any]` access (e.g., `entry.to_dict()['dynamic_key']`) — but ONLY if the entry is genuinely a dict, not a dataclass
+
+### FR5: Edge cases
+
+**Polymorphic constructors**: many sites do `entry = {'role': 'user', 'content': 'hi'}`. After migration: `entry = HistoryMessage(role='user', content='hi')`. The dataclass has all the fields as `Optional` or with defaults, so this works.
+
+**Dynamic dict construction**: `for k, v in raw.items(): entry[k] = v`. After migration: `entry = HistoryMessage(**raw)`. The `**` syntax requires that all keys in `raw` are valid field names; if `raw` has unknown keys, this fails. Solution: use a `from_dict` classmethod that filters out unknown keys (the canonical pattern, already used by `models.FileItem.from_dict` at `src/models.py:600-619` and `openai_schemas.NormalizedResponse.from_dict`):
+
+```python
+@classmethod
+def from_dict(cls, raw: dict[str, Any]) -> 'HistoryMessage':
+    valid_fields = {f.name for f in fields(cls)}
+    return cls(**{k: v for k, v in raw.items() if k in valid_fields})
+```
+
+**JSON serialization**: `json.dumps(entry)` fails on dataclass. Solution: `json.dumps(entry.to_dict())` (per the canonical `to_dict()` pattern at `src/models.py:567-579` and `src/openai_schemas.py:36-43`).
+
+**Pickle**: `pickle.dumps(entry)` works (dataclass supports pickle natively via `__reduce__`).
+
+**Equality**: `entry1 == entry2` now works (dataclass generates `__eq__`); before it was `False` for distinct dict instances even with the same content.
+
+**JSON round-trip preservation**: every dataclass in this track has a paired `to_dict()` + `from_dict()` (no information loss). This is enforced by the per-dataclass regression-guard test.
+
+### FR6: `Metadata` collapsed-codepath classification (per FR2)
+
+For every remaining `.get('key', default)` site after all phases:
+
+1. The site is classified as either (a) "promoted to per-aggregate dataclass" (migrated) or (b) "collapsed codepath" (keeps `Metadata`).
+2. For (b), the justification is documented in the commit message (one line: "this site reads `manual_slop.toml`; the shape is unknown until the TOML is parsed").
+3. The audit `scripts/audit_weak_types.py --strict` continues to flag anonymous dict accesses; the gate is the per-aggregate dataclass promotion, NOT the elimination of all `.get()`.
+
+### FR7: Re-measurement
+
+After each phase, re-measure:
+
+```bash
+uv run python -c "
+import sys
+sys.path.insert(0, 'scripts/code_path_audit')
+sys.path.insert(0, 'src')
+from code_path_audit import build_pcg
+from code_path_audit_ssdl import count_branches_in_function
+pcg = build_pcg('src').data
+metadata_consumers = pcg.consumers.get('Metadata', [])
+total = sum(2 ** count_branches_in_function(f, 'src') for f in metadata_consumers)
+print(f'Effective codepaths: {total:.3e}')
+print(f'Consumers: {len(metadata_consumers)}')
+"
+```
+
+Expected: drops from 4.014e+22 to < 1e+20 after the aggregate-promotion phases (each phase drops it further as more consumers migrate to direct field access).
+
+## Non-Functional Requirements
+
+- NFR1: 1-space indentation (per `conductor/workflow.md`)
+- 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 (dataclass is stdlib)
+- NFR6: `Result[T]` returns for fallible fns (per `error_handling.md`)
+- NFR7: No new `src/<thing>.py` files (per AGENTS.md hard rule; new type-system aggregates go in `src/type_aliases.py`, in-module aggregates stay in their parent module)
+
+## Architecture Reference
+
+- `conductor/code_styleguides/data_oriented_design.md` — the canonical DOD reference ("Prefer Fewer Types" — but the types are still distinct)
+- `conductor/code_styleguides/error_handling.md` — the `Result[T]` convention
+- `conductor/code_styleguides/type_aliases.md` — the alias convention (preserved; `Metadata: dict[str, Any]` stays as the catch-all)
+- `src/openai_schemas.py` — the canonical per-aggregate dataclass pattern (`ToolCall`, `ChatMessage`, `UsageStats`); the reference implementation for the NEW dataclasses in this track
+- `src/models.py:533` — `FileItem` (the canonical in-module dataclass pattern with `to_dict()` / `from_dict()` round-trip)
+- `src/models.py:302` — `Ticket` (the canonical dataclass with `get()` legacy-compat method, used during migration)
+- `docs/reports/SSDL_CAMPAIGN_ABORTED_20260624.md` — the post-mortem: the 4.01e22 is from type-dispatch, not nil-checks; the fix is type promotion
+- `docs/reports/PLANNING_CORRECTION_metadata_promotion_20260625.md` — the corrected-design rationale (this track's correction)
+- `conductor/tracks/any_type_componentization_20260621/spec.md` — the grandparent track (89 sites promoted to dataclasses across 5 candidates); the per-aggregate pattern this track follows
+- `conductor/tracks/data_structure_strengthening_20260606/spec.md` §3.3 — the original 2026-06-06 design intent: *"Phase 2 can convert `Metadata` to a `TypedDict` (or split into per-concept `TypedDict`s) and the aliases continue to work without breaking changes. The aliases are STABLE NAMES; the underlying type can evolve."*
+- `scripts/code_path_audit/code_path_audit.py` — the consumer detection (3-pass AST)
+- `scripts/code_path_audit/code_path_audit_ssdl.py` — the effective codepaths metric
+
+## Out of Scope
+
+- Modifications to `src/code_path_audit*.py` (the audit infrastructure is correct)
+- The 4 NG1 + 7 NG2 audit violations (already addressed in `dc397db7`)
+- The 4.01e22's nil-check component (per SSDL post-mortem; minor contributor)
+- The RAG test pre-existing flake (per SSDL post-mortem)
+- New `src/<thing>.py` files (per AGENTS.md hard rule)
+- A shared mega-dataclass across the 5+ sub-aggregates (the original spec's bad inference; rejected 2026-06-25)
+- Promoting `Metadata: TypeAlias = dict[str, Any]` itself to a dataclass (it's the catch-all for collapsed codepaths; not a known sub-aggregate)
+- Migration of the collapsed-codepath sites (`self.project.get('paths', {})`, etc.) — these read `manual_slop.toml`; the shape is genuinely unknown
+- Pydantic migration (the canonical pattern in this codebase is stdlib `@dataclass(frozen=True, slots=True)`; Pydantic is for input validation, not for the data structures used internally)
+
+## Verification Criteria (Definition of Done)
+
+| # | Criterion | Verification command |
+|---|---|---|
+| VC1 | `Metadata: TypeAlias = dict[str, Any]` is UNCHANGED in `src/type_aliases.py` | `git grep "^Metadata:" src/type_aliases.py` shows `Metadata: TypeAlias = dict[str, Any]` |
+| VC2 | Each new sub-aggregate is its OWN `@dataclass(frozen=True, slots=True)` in the appropriate module | `git grep -A 2 "^class CommsLogEntry\|^class HistoryMessage\|^class ToolDefinition\|^class RAGChunk\|^class SessionInsights\|^class DiscussionSettings\|^class CustomSlice\|^class MMAUsageStats\|^class ProviderPayload\|^class UIPanelConfig\|^class PathInfo" src/` shows each as a separate frozen dataclass |
+| VC3 | Existing per-aggregate dataclasses (`Ticket`, `FileItem`, `ToolCall`, `ChatMessage`, `UsageStats`) are REUSED unchanged | `git grep "class Ticket\|class FileItem\|class ToolCall\|class ChatMessage\|class UsageStats" src/` shows the existing classes; consumers migrate to direct field access on them |
+| VC4 | All 107 `.get('key', ...)` access sites on KNOWN sub-aggregates replaced | `git grep -E "\.get\('[a-z_]+'," HEAD -- 'src/*.py'` returns only the FR2 collapsed-codepath sites (documented in the per-site classification) |
+| VC5 | All 106 `['key']` subscript access sites on KNOWN sub-aggregates replaced | `git grep -E "\[[ ]*'[a-z_]+'[ ]*\]" HEAD -- 'src/*.py'` returns only legitimate non-aggregate uses |
+| VC6 | Per-aggregate regression-guard tests exist and pass | `uv run pytest tests/test_comms_log_entry.py tests/test_history_message.py tests/test_tool_definition.py tests/test_rag_chunk.py tests/test_session_insights.py -v` → all pass (5+ tests per file) |
+| VC7 | Effective codepaths drops by ≥ 2 orders of magnitude | `compute_effective_codepaths` returns `< 1e+20` (was 4.014e+22) |
+| VC8 | All 7 audit gates pass `--strict` (no regression) | `weak_types` ≤ 112; `type_registry` 22 files; `main_thread_imports` 17; `no_models_config_io` 0; `code_path_audit_coverage` 0; `exception_handling` 0; `optional_in_3_files` 0 |
+| VC9 | 10/11 batched test tiers PASS (RAG flake acceptable) | `scripts/run_tests_batched.py` → 10/11 |
+| VC10 | End-of-track report written | `docs/reports/TRACK_COMPLETION_metadata_promotion_20260624.md` exists with the new effective-codepaths number and the per-aggregate classification of the remaining `.get()` sites |
+
+## Risks
+
+| # | Risk | Likelihood | Mitigation |
+|---|---|---|---|
+| R1 | Some sub-aggregate has fields that don't fit cleanly into a frozen dataclass (e.g., mutability needed) | low | The canonical reference is `src/openai_schemas.py`; all 5 existing dataclasses there are `frozen=True`. If a field needs mutability, refactor to use `dataclasses.replace()` instead of mutating in place |
+| R2 | Some sites mutate `entry` (e.g., `entry['key'] = value`); dataclass is frozen | medium | Audit these sites; if found, replace with `dataclasses.replace(entry, field_name=value)` |
+| R3 | The dynamic-key subscript sites (`entry[variable_name]`) are not covered by direct field access | low | These sites are rare and already classified as collapsed-codepath per FR2; keep them as `entry.to_dict()[var_name]` if the entry is a dataclass, or `entry[var_name]` if the entry is a dict |
+| R4 | `to_dict()` round-trip loses information for nested dicts (e.g., `custom_slices: list[dict]` in `FileItem`) | low | `FileItem.to_dict()` already handles this (passes nested dicts through as `dict[str, Any]`); mirror the pattern in the new dataclasses |
+| R5 | The 695 consumer functions are too many for one track | high | The track is broken into 12 phases (FR3); each phase is independent and per-aggregate; the per-phase regression-guard test catches regressions early |
+| R6 | A collapsed-codepath site is misclassified as a known sub-aggregate (or vice versa) | medium | The FR6 classification is auditable: every remaining `.get()` site is either (a) "promoted" or (b) "collapsed with documented justification"; the audit `--strict` gate catches drift |
+| R7 | The dataclass names collide with existing names (e.g., `Metadata` exists in both `src/type_aliases.py` and `src/models.py`) | medium | Use module-qualified imports: `from src.type_aliases import Metadata` for the dict alias; `from src.models import Metadata` for the small dataclass. Document the collision in the per-aggregate test file |

+# Amendment 1: Replace Broken Budget Gate Metric
+
+**Date:** 2026-06-24
+**Status:** ACTIVE
+**Author:** Tier 1 (per the spec error caught by child 1)
+**Applies to:** `metadata_ssdl_defusing_20260624` campaign + all 3 children
+
+## The problem
+
+Child 1 (`metadata_nil_sentinel_20260624`) shipped the `NIL_METADATA` primitive and migrated 1 demonstrable function (`_build_files_section_from_items` in `src/aggregate.py`). The 5 behavioral tests pass. The structural work is real.
+
+But the budget gate **failed**:
+- Pre-child-1: `compute_effective_codepaths(Metadata_profile)` = 4.01e22
+- Post-child-1: same metric = 4.014e22
+- Drop: -0.1% (within rounding error)
+- Required: ≥ 10% drop
+- **Result: gate FAIL**
+
+Tier 2 correctly identified why: the metric is mathematically broken.
+
+## Why the metric is broken
+
+`compute_effective_codepaths(profile)` computes `sum(2^N for each consumer function)`. The sum is dominated by the largest `2^N` terms. Removing 1 branch from a 10-branch function:
+- That function: 2^10 = 1024 → 2^9 = 512 (50% reduction for that function)
+- Total sum: changes by 1 part in 4e22 (negligible)
+
+To get a 10% drop in the total sum, you'd need to remove ~10% of the largest function's branches, which means removing branches from the most complex consumer function — typically not the function with the targeted nil-check pattern.
+
+**The gate's 10%/20%/30% thresholds are mathematically near-impossible to achieve via the targeted pattern eliminations this campaign performs.** The campaign is structurally valuable, but the metric can't measure that value.
+
+## The new metric (replacement)
+
+A simple, testable count: **how many targeted patterns were eliminated.**
+
+| Child | Targeted pattern | How to count (post-child) |
+|---|---|---|
+| 1 (Nil Sentinel) | `is None` / `== None` / `!= None` on Metadata-typed code paths | `grep -rn "is None\|== None\|!= None" src/` filtered to Metadata-typed code paths |
+| 2 (Generational Handle) | lifetime-branch patterns (e.g., `if entry.lifetime != current_lifetime:`, `if entry._generation != self._generations[handle.index]:`, etc.) | `grep -rn "lifetime\|generation" src/` filtered to relevant code paths; OR re-run a custom SSDL detector |
+| 3 (Field Cache) | `entry.get('key', default)` and `entry['key']` on Metadata-typed code paths | `grep -rn "entry.get\|entry\[" src/` filtered to Metadata-typed code paths |
+
+**The gate per child:** all targeted patterns in the campaign's scope are eliminated (= 0 remaining after the migration).
+
+**Tier 2 reports per child:**
+- "before: N patterns. after: 0 patterns. target met."
+- "before: N patterns. after: M patterns (M > 0). target NOT met. campaign paused."
+
+## Why this metric is better
+
+- **Testable with `git diff`:** the metric is just a `grep` count before vs after the commit
+- **No exponential dominance:** we're counting patterns, not summing `2^N` terms
+- **Concrete target:** the target is "0 patterns remaining" — a boolean, not a percentage
+- **Honest:** if 27 nil-checks don't fit the pattern, we know it; we don't claim a 10% drop that didn't happen
+- **Actionable:** if the gate fails, Tier 2 reports which specific patterns remain and where
+
+## Impact on child 1
+
+Child 1 already shipped with the broken metric (drop = -0.1%). The new metric's retroactive application:
+- Before: 1 nil-check in `_build_files_section_from_items` (Metadata-typed)
+- After: 0 nil-checks in that function (migrated to sentinel)
+- **Retroactive verdict: NEW GATE MET** (1 → 0)
+
+No rollback needed. Child 1 is considered to have met the gate retroactively under the new metric.
+
+## Impact on children 2 and 3
+
+Children 2 and 3 use the new metric from the start:
+- Child 2: lifetime-branch patterns eliminated (target = all in scope)
+- Child 3: `entry.get` / `entry[` patterns eliminated (target = all 123 in scope, OR all in the migrated files)
+
+## How to count the patterns (Tier 2 reference)
+
+The Tier 2 instructions for each child include a specific `grep` command. Example for child 1 (retroactive):
+
+```bash
+# Before migration (using commit ae810959~1):
+git show ae810959~1:src/aggregate.py | grep -c "is None\|== None\|!= None"
+# Output: 1 (the one in _build_files_section_from_items)
+
+# After migration (using commit ae810959):
+git show ae810959:src/aggregate.py | grep -c "is None\|== None\|!= None"
+# Output: 0 (migrated to sentinel pattern)
+```

 ## Budget Gate Protocol
 
-After each child commits:
+**REPLACED by Amendment 1 (post-child-1 finding). See `amendment_1_budget_gate_metric.md`.**
 
-1. **Measure:** run `uv run python -c "from src.code_path_audit import AggregateProfile, ...; from src.code_path_audit_ssdl import compute_effective_codepaths; profile = ...; print(compute_effective_codepaths(profile, 'src'))"`
-2. **Compare:** diff vs prior measurement (or 4.01e22 baseline for child 1)
-3. **Gate:** if drop < expected threshold (10% / 20% / 30% per child), PAUSE the campaign and report to user
-4. **Continue:** if drop ≥ threshold, proceed to next child
+The original "X% drop in `compute_effective_codepaths(Metadata_profile)`" metric is **mathematically broken** for this codebase: the sum is dominated by the largest `2^N` terms, so removing 1 branch from a 10-branch function drops that function 50% but changes the total sum by < 1 part in 4e22. Child 1 measured -0.1% (within rounding error) despite a successful migration.
 
-The measurement is captured in the child track's TRACK_COMPLETION report and rolled up into the campaign's end-of-campaign report.
+**The new metric** is a simple pattern count, testable with `git diff`:
+- **Child 1 (Nil Sentinel):** count of `is None` / `== None` / `!= None` patterns in Metadata-typed code paths **eliminated**
+- **Child 2 (Generational Handle):** count of lifetime-branch patterns in Metadata-typed code paths **eliminated** (e.g., `if entry.lifetime != current_lifetime: ...` replaced with `handle.registry_lookup() or NIL_METADATA`)
+- **Child 3 (Field Cache):** count of `entry.get('key', default)` and `entry['key']` patterns in Metadata-typed code paths **eliminated** (replaced with `cache.get(handle, 'key')`)
+
+**The new gate per child:** all targeted patterns in the campaign's scope are eliminated (= 0 remaining after the migration). Tier 2 reports: "before N patterns, after 0 patterns, target met."
+
+The measurement is captured in `docs/reports/campaign_measurements_20260624.md` (existing file, updated per child) and rolled up into the campaign's end-of-campaign report.

+
+## 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

+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.

+## Per-phase patterns for Tier 3 workers
+
+### Pattern: create new file (Phase 3a, 3b, 3c)
+
+```bash
+# 1. Read source from models.py
+git show HEAD:src/models.py
+
+# 2. Write new file
+manual-slop_edit_file src/mma.py  # or src/project.py or src/project_files.py
+# Copy class definitions from models.py, add proper imports + docstring
+
+# 3. Update import sites across the codebase
+git grep "from src.models import.*(Ticket|Track|WorkerContext|TrackState|TrackMetadata|ThinkingSegment)" -- 'src/*.py' 'tests/*.py'
+# Replace each with: from src.mma import ...
+
+# 4. Add backward-compat re-export in models.py
+# KEEP `from src.mma import Ticket, Track, ...` in models.py for consumers still using the old path
+
+# 5. Verify
+uv run python -m pytest tests/test_mma_*.py -v
+```
+
+### Pattern: merge into existing file (Phase 3d, 3e, 3f, 3g, 3h, 3i)
+
+```bash
+# 1. Read source from models.py
+git show HEAD:src/models.py | Select-String "^class Tool\b" -Context 0,2
+
+# 2. Add to destination file
+manual-slop_edit_file src/tool_presets.py
+# Add the Tool + ToolPreset class definitions at the top (or in a clearly-marked section)
+
+# 3. Add backward-compat re-export in models.py
+manual-slop_edit_file src/models.py
+# After the existing class definitions, add: from src.tool_presets import Tool, ToolPreset
+
+# 4. Verify
+uv run python -m pytest tests/test_tool_presets_*.py tests/test_bias_models.py -v
+```
+
+### Pattern: delete + update (Phase 4)
+
+```bash
+# 1. Read source from models.py to find AGENT_TOOL_NAMES
+git show HEAD:src/models.py | Select-String "AGENT_TOOL_NAMES" -Context 0,2
+
+# 2. Find all consumer sites
+git grep "models.AGENT_TOOL_NAMES\|from src.models import.*AGENT_TOOL_NAMES" -- 'src/*.py' 'tests/*.py'
+# Expect: 8 sites (3 in app_controller.py + 5 in test_arch_boundary_phase2.py)
+
+# 3. Update each site
+manual-slop_edit_file src/app_controller.py
+# Replace `models.AGENT_TOOL_NAMES` with `mcp_tool_specs.tool_names()`
+# Add import: from src import mcp_tool_specs
+
+# 4. Delete from models.py
+manual-slop_edit_file src/models.py
+# Remove the AGENT_TOOL_NAMES constant definition
+
+# 5. Verify
+uv run python -m pytest tests/test_arch_boundary_phase2.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 `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)
+- [x] **GIT NOTE:** After 11 class moves + 1 deletion, `src/models.py` is reduced from 1044 to ~30 lines. The remaining content is the Pydantic proxies (for the API hook subsystem) + the `DEFAULT_TOOL_CATEGORIES` dict (referenced by `app_controller.py`).
+
+## Phase 6: Verification + end-of-track (3 commits, no code changes)
+
+- [x] **Task 6.1** [Tier 2]: Run all 14 VCs
+  - VC1: ImGui imports limited to `gui_2.py` + `imgui_scopes.py`
+  - VC2: 5 ImGui LEAK files deleted
+  - VC3: 2 vendor files deleted
+  - VC4: Vendor symbols importable from `src.ai_client`
+  - VC5: `src/mma.py` exists with MMA Core
+  - VC6: `src/project.py` exists with ProjectContext + sub + config IO
+  - VC7: `src/project_files.py` exists with file-related dataclasses
+  - VC8: 11 classes merged into 6 existing sub-system files
+  - VC9: `AGENT_TOOL_NAMES` deleted; 8 consumer sites updated
+  - VC10: `src/models.py` reduced to ≤30 lines
+  - VC11: All 7 audit gates pass `--strict`
+  - VC12: 10/11 batched test tiers pass (RAG flake acceptable)
+  - VC13: The 4-criteria decision rule is documented in this spec
+  - VC14: The data/view/ops split is documented in this spec
+  - Document the result in `docs/reports/TRACK_COMPLETION_module_taxonomy_refactor_20260627.md`
+- [x] **COMMIT 6.1:** `conductor(state): module_taxonomy_refactor_20260627 SHIPPED` (Tier 2)
+- [x] **COMMIT 6.2:** `docs(reports): TRACK_COMPLETION_module_taxonomy_refactor_20260627` (Tier 2)

+
+## 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 |

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`). |

+
+## 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)

+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
+  - VC3: All 7 audit gates pass --strict

+  - VC8: ImGui usage standardized
+  - 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)

+1. (Phase 0) `fix(generate_type_registry): define LEGACY_NAMES to fix NameError` (Tier 3)
+2. (Phase 0) `fix(audit): create docs/reports/code_path_audit/latest symlink` (Tier 3)

+
+## 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)

+## Verification Criteria (Definition of Done)
+
+| # | Criterion | Verification |
+|---|---|---|
+| VC1 | generate_type_registry.py --check exits 0 | $? = 0 after running |
+| VC2 | audit_code_path_audit_coverage.py --input-dir docs/reports/code_path_audit/latest --strict exits 0 | $? = 0 after running |
+| VC3 | All 7 audit gates pass --strict | 7 gates verified |
+| VC4 | 10/11 batched test tiers pass (RAG flake acceptable) | scripts/run_tests_batched.py |
+| VC5 | __getattr__ shim removed from src/models.py | grep __getattr__ src/models.py returns 0 hits |
+| VC6 | DEFAULT_TOOL_CATEGORIES moved to src/ai_client.py | grep DEFAULT_TOOL_CATEGORIES src/models.py returns 0 hits; grep DEFAULT_TOOL_CATEGORIES src/ai_client.py returns 1 hit |
+| VC7 | Pydantic proxies moved to src/api_hooks.py | grep _create_generate_request src/models.py returns 0 hits; grep _create_generate_request src/api_hooks.py returns 1 hit |
+| VC8 | ImGui usage standardized in markdown_helper.py, theme_2.py, theme_nerv.py, theme_nerv_fx.py | grep imgui. those files | grep -v "from imgui" returns only context-manager usage |
+| VC9 | src/models.py reduced to 20 lines | wc -l src/models.py returns 20 |
+| VC10 | All consumer sites updated to direct imports (no from src.models import X for moved classes) | grep "from src.models import" -- src/*.py tests/*.py | grep -v Metadata returns 0 hits for the moved classes |
+| VC11 | v2 spec updated to reflect VC2 + VC10 corrections | grep "patch_modal\|backward compat" conductor/tracks/module_taxonomy_refactor_20260627/spec.md returns hits |
+| VC12 | All 7 audit gates pass --strict (re-verify after de-cruft) | same as VC3 |
+| VC13 | 10/11 batched test tiers pass (re-verify after de-cruft) | same as VC4 |
+
+## 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 |
