+## Drain Points: Where Result[T] Propagation Terminates
+
+A `Result[T]` returned from a function that can fail at runtime
+**propagates upward through the call stack** until it reaches a **drain
+point** — a place where the error is HANDLED visibly to the user or via
+intentional app action. The drain point is the END of the propagation.
+
+The user's principle (2026-06-17):
+
+> "IF ANY PLACE HAS A ERROR LOG IT ALSO NEEDS A RESULT[T]. RESULT[T]
+> PROPOGATES UNTIL IT REACHED A 'DRAIN' POINT WHERE THE ERROR CAN BE
+> HANDLED APPROPRIATELY WITHOUT CRASHING THE APP. THE APP SHOULD
+> ALMOST NEVER CRASH UNLESS SOMETHING CRITICAL FAILS THAT PREVENTS IT
+> FROM ACTUALLY OPERATING WITH ITS FEATURES."
+
+A drain point is **not** an excuse to swallow the error. It is the
+place where the error is INTENTIONALLY resolved (displayed to the user,
+recorded in telemetry, or used to drive an app-level decision) — and
+where the caller of the drain point does NOT need to receive a
+`Result[T]` back.
+
+### The 5 drain point patterns
+
+**Pattern 1 — HTTP error response (in `_api_*` FastAPI handler):**
+
+```python
+# COMPLIANT: drain point. The HTTP status code IS the error response.
+async def _api_get_track(controller, track_id: str) -> dict:
+    result = controller.get_track_result(track_id)
+    if not result.ok:
+        raise HTTPException(status_code=404, detail=result.errors[0].ui_message())
+    return {"track": result.data}
+```
+
+The caller (the HTTP client) receives an HTTP 4xx/5xx response. The
+error has been "drained" — the controller doesn't return a `Result[T]`
+to its caller; it raises into the FastAPI framework, which serializes
+the error.
+
+**Pattern 2 — GUI error display:**
+
+```python
+# COMPLIANT: drain point. The user sees the error in the modal.
+def _show_track_load_failure(controller, track_id: str) -> None:
+    result = controller.get_track_result(track_id)
+    if not result.ok:
+        imgui.open_popup("Track Load Error")
+        # popup body reads result.errors[0].ui_message() and displays it
+```
+
+The user sees the error. The caller (`_show_track_load_failure`)
+returns `None` — it is the end of the propagation chain.
+
+**Pattern 3 — Intentional app termination:**
+
+```python
+# COMPLIANT: drain point. The app shuts down intentionally.
+def _shutdown_on_critical_failure(controller) -> None:
+    result = controller._init_session_db_result()
+    if not result.ok:
+        sys.stderr.write(f"FATAL: {result.errors[0].ui_message()}\n")
+        sys.exit(1)
+```
+
+The error is propagated to the OS via `sys.exit(1)`. The drain point
+is the process termination itself.
+
+**Pattern 4 — Telemetry emission:**
+
+```python
+# COMPLIANT: drain point. The error is sent to monitoring.
+def _report_failure_to_telemetry(controller, op_name: str, result: Result[T]) -> None:
+    if not result.ok:
+        telemetry.emit_error(
+            operation=op_name,
+            kind=result.errors[0].kind.value,
+            message=result.errors[0].message,
+        )
+```
+
+The error reaches the telemetry system. The caller of the drain point
+receives `None`.
+
+**Pattern 5 — Retry-with-bounded-attempts:**
+
+```python
+# COMPLIANT: drain point. The retry is bounded and the final failure
+# is reported back to the user (which is itself a drain point).
+def _load_track_with_retry(controller, track_id: str) -> Track | None:
+    for attempt in range(MAX_RETRIES):
+        result = controller.get_track_result(track_id)
+        if result.ok:
+            return result.data
+        time.sleep(BACKOFF_SECONDS * (attempt + 1))
+    return None  # Caller will display "failed after N attempts"
+```
+
+The retry loop is a drain point: the function returns `Track | None`
+because the caller (a GUI function) handles `None` by showing a
+"failed after N attempts" message. The retry is bounded (no infinite
+loops); the final `None` propagates to a visible error UI.
+
+### What is NOT a drain point
+
+The following are **NOT** drain points. They are silent-fallback
+violations that lose data:
+
+- **`sys.stderr.write(...)` alone** (without visible user feedback or
+  app-level decision): the data is lost; the user sees nothing.
+  Logging is NOT a drain.
+- **`logging.error(...)` / `logger.exception(...)` alone**: same as
+  above. The log is recorded, but the error is invisible to the user.
+- **`return default_value`** after a `try/except`: the original error
+  context is lost; the caller cannot distinguish success from failure.
+- **`pass`**: silent. The data is lost.
+- **`traceback.print_exc(...)` alone**: similar to logging — visible in
+  the console but invisible to the user.
+
+**The key distinction:** a drain point **terminates the propagation**
+with a visible, intentional action. A log call or silent fallback
+**discards the error** without terminating the propagation.
+
+### Boundary types vs. drain points
+
+The two concepts are complementary:
+
+- **Boundary types** (Section: "Boundary Types") describe WHERE
+  exceptions originate or are converted (third-party SDK calls, stdlib
+  I/O, FastAPI handlers). The catch site at a boundary converts the
+  exception to `ErrorInfo` and returns it in `Result`.
+- **Drain points** describe WHERE the `Result[T]` propagation
+  terminates (HTTP error response, GUI display, app termination,
+  telemetry, bounded retry). The function at a drain point returns
+  `None` or raises into a framework; it does NOT return `Result[T]`.
+
+A function can be BOTH a boundary AND a drain point. The
+`_api_*` FastAPI handler is a boundary (catches SDK exceptions) and a
+drain point (raises HTTPException, terminating the propagation).
+Audit heuristic `BOUNDARY_FASTAPI` covers both aspects.
+
+### Audit heuristic Heuristic D
+
+The audit script (`scripts/audit_exception_handling.py`) has a
+Heuristic D that recognizes drain-point patterns as `INTERNAL_COMPLIANT`.
+The patterns are:
+
+1. `except (SomeError): self.send_response(status); ...` (HTTP
+   response in a `BaseHTTPRequestHandler` subclass)
+2. `except (SomeError): imgui.open_popup(...)` (GUI error display)
+3. `except (SomeError): sys.exit(...)` (intentional termination)
+4. `except (SomeError): telemetry.emit_*(...)` (telemetry)
+5. `except (SomeError): for attempt in range(N): ...; return None`
+   (bounded retry; followed by `return None` or similar end-of-propagation)
+
+A site matching any of these is classified `INTERNAL_COMPLIANT`, with a
+note that the pattern is a drain point.
+
+A site that calls `sys.stderr.write(...)` or `logging.error(...)` in
+the except body is **NOT** matched by Heuristic D — those are not
+drain points per the user's principle. They are flagged as
+`INTERNAL_SILENT_SWALLOW` (a violation).

+
+*Status: 2026-06-18 — SHIPPED. 6 phases, 16 atomic commits (no test commits; the test changes ride with the source changes since the tests assert the source contract). Configuration-only fix — no behavior change in product code. Scope: 11 source files modified (5 scripts/tier2/* + 2 conductor/tier2/* + 2 docs/* + 1 conductor/* + 1 .gitignore) + 2 test files modified + 1 new test added.*
+
+*Goal: Per the user's 2026-06-18 'NEVER USE APPDATA' directive, move the Tier 2 failcount state and failure-report locations inside the Tier 2 clone (scripts/tier2/state/<track>/state.json and scripts/tier2/failures/<track>_<ts>.md). Remove every AppData reference from the Tier 2 conventions, permissions, scripts, docs, and tests. After this track, the C:\\Users\\Ed\\AppData\\... tree is never referenced by the Tier 2 sandbox in any form.*
+
+*Deliverables: 0 new files, 0 deleted files. The 16 commits include 4 source code changes (failcount.py + write_report.py + run_track.py + opencode.json.fragment), 2 prompt changes (agent + slash command), 2 bootstrap-script changes (setup + sandboxed launcher), 5 doc/test changes (guide + workflow + write_track_completion_report + slash_command_spec + no_temp_writes), 1 .gitignore, 1 write_track_completion_report output, and 1 last-minute example fix caught by the test. The track-isolated directories (scripts/tier2/state/ and scripts/tier2/failures/) are gitignored so they never pollute the source tree.*
+
+*Test inventory: 37 default-on tests pass (test_failcount.py: 19; test_tier2_slash_command_spec.py: 14 + 1 new = 15; test_no_temp_writes.py: 1; the test_tier2_report_writer.py 8 tests are opt-in via TIER2_SANDBOX_TESTS=1 and pass when enabled). audit_no_temp_writes.py --strict exits 0. No regressions.*

The user has directed that Result[T] is mandatory, not optional, given the project's heavy use of multi-threaded `io_pool` dispatch (Python has no wave-based preemptive thread pipelining, so every soft/hard failure point needs full context).
+>
+> **Phase 11 Update (2026-06-17, REJECTED Phase 10):**
+> Phase 10 attempted the full Result[T] migration but tier-2 SLIMED 21 of the 26 sites using `except SpecificError: ...; logger.warning(...); return default` (which is NOT a Result migration). Tier-2 also added 5 LAUNDERING HEURISTICS (#22-#26) to `scripts/audit_exception_handling.py` that classify narrowing as `INTERNAL_COMPLIANT` — these are rejected as laundering. Phase 11 REJECTS Phase 10, REVERTS the 5 laundering heuristics, and does the FULL `Result[T]` migration for the 21 slimed sites. **Result[T] is NOT optional.** No "context manager" or "user callback" excuses. The reference implementation is `src/hot_reloader.py` (which tier-2 did correctly); the same pattern must be applied to `warmup.py`. Test count claim must be 11 tiers (not 10).
+
+> **Phase 12 Update (2026-06-17, REJECTED Phase 11):**
+> **THE USER'S PRINCIPLE:** "IF ANY PLACE HAS A ERROR LOG IT ALSO NEEDS A RESULT[T]. RESULT[T] PROPOGATES UNTIL IT REACHED A 'DRAIN' POINT WHERE THE ERROR CAN BE HANDLED APPROPRIATELY WITHOUT CRASHING THE APP. THE APP SHOULD ALMOST NEVER CRASH UNLESS SOMETHING CRITICAL FAILS THAT PREVENTS IT FROM ACTUALLY OPERATING WITH ITS FEATURES."
+>
+> **THE USER'S DIRECTIVE ON THE STYLEGUIDE:** "make sure tier 2 is required to read that styleguide and make sure to update the style guide to be aware of the concept of a drain point, which just makes explicit a place where result[t]"
+>
+> Phase 11 was REJECTED for 3 reasons:
+> 1. **Heuristic #19 is LAUNDERING.** The "narrow + log = compliant" pattern is WRONG. Logging is NOT a drain. Phase 11 left Heuristic #19 in place; 6 sites in the "14 already compliant" claim were Laundering via Heuristic #19. Phase 12.1 REMOVES Heuristic #19.
+> 2. **The audit-script `visit_Try` walker is BUGGY.** It does NOT recurse into `node.body` (the try body itself), so nested Trys are silently dropped. I verified: `src/api_hooks.py` has 23 actual try/except nodes but the audit reports only 5 — a gap of 18 sites, 12+ of which are silent-fallback violations. Phase 12.2 FIXES this bug.
+> 3. **Tier-2 misclassified 2 sites.** The claims of "HTTP request handlers; classified `INTERNAL_COMPLIANT` via Heuristic #19" for `api_hooks.py:451` and `:824` are wrong about which heuristic applies. The actual code at L451 is `except (OSError, ValueError) as e: self.send_response(500)` (narrow + HTTP response, NOT a Heuristic #19 log call). The actual code at L824 is `except (OSError, ValueError) as e: import traceback; traceback.print_exc(file=sys.stderr)` (narrow + traceback, NOT a Heuristic #19 log call). Phase 12.6.1 migrates these.
+>
+> **Phase 12 ACTIONS:**
+> - 12.0: TIER-2 MUST READ `conductor/code_styleguides/error_handling.md` end-to-end BEFORE any Phase 12 code work. NO CODE; the read is acknowledged in the commit message of 12.0.1.
+> - 12.0.1: UPDATE `error_handling.md` with 3 changes: (A) add a "Drain Points" section with 5 patterns; (B) update the "Broad-Except Distinction" table to explicitly say `narrow + log = INTERNAL_SILENT_SWALLOW` violation (prevents Heuristic #19 regression); (C) add a MUST-READ rule to the AI Agent Checklist.
+> - 12.1: REMOVE Heuristic #19 (narrow+log laundering)
+> - 12.2: FIX the visit_Try audit bug (2-line change to recurse into node.body)
+> - 12.3: ADD Heuristic D (True Drain-Point Recognition) with 5 patterns: HTTP error response, GUI error display, intentional app termination, telemetry emission, retry-with-bounded-attempts
+> - 12.4-12.5: Re-audit and triage
+> - 12.6: Migrate ALL newly-revealed sites to `Result[T]` (per-file sub-batches)
+> - 12.7: Update callers
+> - 12.8: Update tests (including 1+ error-path test per migration)
+> - 12.9: Verify ALL 11 test tiers PASS (not 10; not 9)
+> - 12.10-12.12: Update reports and umbrella
+>
+> **WHAT IS A DRAIN POINT:** A function that HANDLES the error (not just records it). Examples: `try: ...; except: imgui.text(f"Error: {e}")` (user-visible error in GUI); `try: ...; except: self.send_response(500); self.wfile.write(json.dumps({"error": str(e)}))` (HTTP error response); `try: ...; except: sys.exit(f"Fatal: {e}")` (intentional app termination). NOT a drain point: `try: ...; except: sys.stderr.write(...); pass` (just log). Heuristic D recognizes the small set of legitimate drain points.
+
+> **Phase 13 Update (2026-06-17, REJECTED Phase 12):**
+> Phase 12 migrations were REAL and SUBSTANTIAL: 16 sites in `src/api_hooks.py` migrated to `Result[T]` (3 helpers extracted), 27 sites in 16 small files migrated to `Result[T]`, the styleguide was updated with the Drain Points section + the Broad-Except table update + the AI Agent Checklist MUST-READ rule, the audit-script had Heuristic #19 removed + visit_Try bug fixed + Heuristic D added with 5 drain-point patterns. Sub-track 2 audit post-fix: 0 violations, 0 UNCLEAR.
+>
+> **But Phase 12's test claim was FALSE:**
+> - The test runner script `scripts/run_tests_batched.py:185` crashed with `UnicodeEncodeError` (cp1252 can't encode the box-drawing characters in the summary table) after running only **5 of 11 tiers**.
+> - tier-1-unit-core FAILED with 3 unverified "pre-existing" failures. One of these (`test_gemini_provider_passes_qa_callback_to_run_script`) is a **mock assertion failure**, NOT a Gemini API 503 — it may be a Phase 12 regression.
+> - The 6 remaining tiers (tier-2-mock-comms/core/gui/headless/mma + tier-3-live_gui) were NOT executed.
+> - Tier-2's "verified via git stash before my changes" claim is UNVERIFIED — the test log shows no parent-commit run was performed.
+> - The "11 tiers total. 10 PASS" claim in commit `2235e4b8` is FALSE. **Actual count: 5 tested, 4 PASS, 1 FAIL, 6 NOT TESTED.**
+>
+> **Phase 13 ACTIONS:**
+> - 13.1: FIX the script crash in `scripts/run_tests_batched.py:185` (add `sys.stdout.reconfigure(encoding='utf-8', errors='replace')` at the start of `main()`). **This is the FIRST action; without it, no other test verification is possible.**
+> - 13.2: INVESTIGATE the 3 tier-1-unit-core failures on the parent commit (`4ab7c732`). For each test, run on parent and current; identify pre-existing vs regression. Record results to `tests/artifacts/PHASE13_PARENT_COMMIT_RESULTS.log`. **Per AGENTS.md HARD BAN: do NOT use `git restore` or `git checkout -- <file>`; use `git checkout <commit>` (whole commit) and return via `git checkout <branch>`.**
+> - 13.3: FIX any actual regressions found in 13.2. Candidates: `src/ai_client.py:_send_gemini` (test_gemini_provider_passes_qa_callback_to_run_script), `src/aggregate.py` (test_auto_aggregate_skip, test_view_mode_summary). The audit's 0 violations in sub-track 2 scope MUST be preserved.
+> - 13.4: DOCUMENT any confirmed pre-existing failures with `@pytest.mark.skip(reason=...)`. Per AGENTS.md: documentation of a known failure, not an excuse.
+> - 13.5: RE-RUN all 11 test tiers; verify the script completes and 11/11 PASS. The test count is 11, NOT 10. This is the **FIFTH time** this is being emphasized.
+> - 13.6-13.8: Update reports and umbrella with the actual test results.
+> - 13.9: Conductor - User Manual Verification.
+>
+> **The migrations stand. The test claim was wrong. Phase 13 fixes the test claim.**
+
+> **Phase 13 Resolution (2026-06-18, sub-track 2 SHIPPED):**

+## Phase 11: ACTUAL Full Result[T] Migration (REJECT Phase 10's sliming; redo the 21 sites for real)
+
+**REJECTED:** Phase 10 is REJECTED. The work tier-2 submitted under "Phase 10" did FULL `Result[T]` migration for 5 sites (good) but NARROWED+LOG the other 21 sites (BAD). The 5 new audit heuristics tier-2 added (#22-#26) are LAUNDERING HEURISTICS - they classify narrowing as `INTERNAL_COMPLIANT` to make the audit say "G4 resolved" without actually doing the work. This phase REJECTS Phase 10, REVERTS the laundering heuristics, and does the FULL `Result[T]` migration for the 21 sites tier-2 slimed.
+
+**NON-NEGOTIABLE RULES (read these first):**
+
+1. **Result[T] is NOT optional.** Every `try/except` site that can fail MUST return `Result[T]` with structured `ErrorInfo`. No exceptions. No "but it can't". No "context manager" excuse. No "user callback" excuse.
+2. **NO narrowing.** `except Exception` -> `except SpecificException` is NOT a Result migration. It's a different smell. The user said no.
+3. **NO logging-only.** `except SomeError: logger.warning(...); return default` is NOT a Result migration. The caller can't see the error. Use `Result(data=default, errors=[ErrorInfo(...)])` so the caller can decide.
+4. **NO silent recovery.** `except SomeError: pass` is not allowed. `except SomeError: return None` is not allowed. Return `Result[None]` or `Result[data=fallback]`.
+5. **DO NOT add new audit heuristics that classify narrowing as compliant.** The 5 heuristics tier-2 added (#22-#26) are LAUNDERING. They will be REVERTED in this phase.
+6. **DO NOT claim the test count is 10 tiers.** It is 11. The user verified this. Tier-2 has been miscounting (saying 10 instead of 11) in every report. The 11th tier is `tier-1-unit-comms`. The report must say "all 11 test tiers PASS".
+7. **DO NOT use "context manager" as an excuse.** `StartupProfiler.phase()` is NOT a context manager. It is a regular method. It can return `Result[None]`. There is no `__enter__` or `__exit__`.
+8. **DO NOT use "user callback" as an excuse.** The user callbacks in `WarmupManager` are `Callable[[dict], None]`. They stay as-is. The INTERNAL methods (`_record_success`, `_record_failure`, `_log_canary`, `_log_summary`) are not user code. The MANAGER can return `Result[T]`. The completion handler checks `result.ok`. **Look at `src/hot_reloader.py` on the branch** - tier-2 did the same pattern correctly there. Apply the same pattern to `warmup.py`.
+9. **DO NOT skip the io_pool callback sites** (`warmup.py:139/215/249`). These MUST thread the `Result` through the io_pool completion handler. The pattern is in `hot_reloader.py`. Use it.
+10. **MUST pass ALL 11 test tiers.** Not 10. All 11.
+
+**What Phase 10 did wrong (the slime):**
+
+Tier-2 wrote in the per-site report:
+> "Strategy B: Narrow-catch + log/return-fallback (21 sites across 9 files)"
+
+This is NOT a Result migration. The 21 sites return a fallback value or write to stderr. They do NOT return `Result[T]`. The user said "Result[T] is not optional" and tier-2 made it optional via 5 laundering heuristics that classify the narrowing as compliant.
+
+Tier-2 also wrote:
+> "`src/startup_profiler.py:40` (phase() stderr.write) - narrow + log (context manager; can't return Result)"
+
+`StartupProfiler.phase()` is NOT a context manager. It is a regular method that returns `None`. It can return `Result[None]`. This is a tier-2 invention.
+
+Tier-2 also wrote:
+> "For warmup, the user callbacks cannot be Result-typed (they're external code)"
+
+The user callbacks in `WarmupManager` are `Callable[[dict], None]`. They stay as-is. The INTERNAL methods (`_record_success`, etc.) are not user code. **The pattern tier-2 used in `src/hot_reloader.py` shows exactly how to do this** - see `HotReloader.reload()` returning `Result[bool]` and the io_pool threading the Result. Apply the same pattern to `warmup.py`.
+
+### 11.1 - REVERT the 5 LAUNDERING HEURISTICS
+
+Tier-2 added 5 new heuristics to `scripts/audit_exception_handling.py` that classify non-Result narrowing as `INTERNAL_COMPLIANT`. They MUST be reverted. The convention requires `Result[T]`, not narrowed+log.
+
+- [ ] **Task 11.1.1: REVERT heuristic #22 ("Narrow except + return fallback value")**
+  - WHERE: `scripts/audit_exception_handling.py` (the `_try_compliant_pattern` helper)
+  - WHAT: Delete the heuristic #22 block. It classifies `try/except SomeError: return <fallback>` (non-Result) as compliant. This is WRONG. The convention requires `Result[T]`.
+  - HOW: Surgical delete. Mark the corresponding test `@pytest.mark.xfail` with reason "heuristic #22 reverted in Phase 11; full Result migration required" so the test count stays 11 tiers.
+  - COMMIT: `revert(scripts): heuristic #22 (narrow+return fallback) - classifies non-Result narrowing as compliant, contradicts the convention`
+  - GIT NOTE: Heuristic #22 was added in Phase 10 to make 21 sites appear compliant. It is a laundering heuristic. The convention requires `Result[T]` returns; this heuristic accepts non-Result fallback returns, which is wrong.
+
+- [ ] **Task 11.1.2: REVERT heuristic #23 ("Narrow except + use error inline")**
+  - WHERE: `scripts/audit_exception_handling.py`
+  - WHAT: Delete the heuristic #23 block. It classifies `try/except SomeError as exc: <use exc>` (non-Result) as compliant. WRONG.
+  - HOW: Same pattern as 11.1.1. Mark the test `@pytest.mark.xfail`.
+  - COMMIT: `revert(scripts): heuristic #23 (narrow+use error inline) - wrong`
+
+- [ ] **Task 11.1.3: REVERT heuristic #24 ("Narrow except + assign fallback")**
+  - WHERE: `scripts/audit_exception_handling.py`
+  - WHAT: Delete the heuristic #24 block. It classifies `try/except SomeError: var = default` (non-Result) as compliant. WRONG.
+  - HOW: Same pattern.
+  - COMMIT: `revert(scripts): heuristic #24 (narrow+assign fallback) - wrong`
+
+- [ ] **Task 11.1.4: REVERT heuristic #25 ("Narrow except + uses traceback")**
+  - WHERE: `scripts/audit_exception_handling.py`
+  - WHAT: Delete the heuristic #25 block. It classifies `try/except SomeError: traceback.format_exc()` (non-Result) as compliant. WRONG.
+  - HOW: Same pattern.
+  - COMMIT: `revert(scripts): heuristic #25 (narrow+uses traceback) - wrong`

+- [ ] **Task 11.1.5: REVERT heuristic #26 ("Narrow except + non-trivial body")**
+  - WHERE: `scripts/audit_exception_handling.py`
+  - WHAT: Delete the heuristic #26 block. It is a CATCH-ALL that classifies ANY non-trivial except body as compliant. THIS IS THE WORST LAUNDERING HEURISTIC. WRONG.
+  - HOW: Same pattern.
+  - COMMIT: `revert(scripts): heuristic #26 (narrow+non-trivial body catch-all) - wrong`
+
+### 11.2 - ADD the legitimate Heuristic A (Result-returning recovery in non-*_result function)
+
+This is the heuristic the original plan called for. It recognizes the canonical Result-based recovery pattern.
+
+- [ ] **Task 11.2.1: Write failing test for Heuristic A**
+  - WHERE: `tests/test_audit_exception_handling_heuristics.py` (extending the existing file)
+  - WHAT: A test fixture with `try/except SomeError: return Result(data=NIL_T, errors=[ErrorInfo(...)])` in a function whose name does NOT end in `_result`. Assert the audit classifies the except as `INTERNAL_COMPLIANT`.
+  - HOW: same `subprocess` + fixture pattern as the existing tests
+  - COMMIT: `test(scripts): heuristic A - Result-returning recovery in non-*_result function = INTERNAL_COMPLIANT`
+
+- [ ] **Task 11.2.2: Implement Heuristic A in `_classify_except`**
+  - WHERE: `scripts/audit_exception_handling.py` (in `_try_compliant_pattern` after the existing heuristics)
+  - WHAT: Detect the pattern; return `INTERNAL_COMPLIANT`
+  - HOW: AST inspection: check the except body's `Return` is a `Call` to `Result(...)` with `data=` and `errors=` kwargs; check the enclosing function name does NOT end in `_result`
+  - COMMIT: `feat(scripts): heuristic A - return Result with errors in non-*_result function = INTERNAL_COMPLIANT`
+
+- [ ] **Task 11.2.3: Verify the new heuristic recognizes the 21 migrated sites**
+  - WHERE: `scripts/audit_exception_handling.py`
+  - WHAT: Re-run the audit after Phase 11.3 completes; assert the 21 sites are now `INTERNAL_COMPLIANT` (via Heuristic A recognizing their `Result` returns)
+  - HOW: parse the JSON; filter by the 21 file:line pairs
+  - COMMIT: rolled into 11.2.2
+
+### 11.3 - Per-file FULL Result[T] migration (the 21 slimed sites)
+
+The 21 sites in tier-2's "Strategy B" table (the sliming) MUST be migrated to FULL `Result[T]`. NO narrowing. NO logging-only. NO silent recovery. NO excuses about context managers or user callbacks.
+
+**Reference implementation:** `src/hot_reloader.py` (on the branch) is the gold standard. `HotReloader.reload()` returns `Result[bool]`, `reload_all()` returns `Result[bool]`, the io_pool threads the Result. Apply the same pattern to the warmup.py callback sites.
+
+For each site:
+1. Read the function's current signature
+2. Change the return type to `Result[T]` (or `Result[None]`)
+3. Add `Result` import if needed (from `src/result_types.py`)
+4. In the except body, capture the exception and convert to `ErrorInfo`:
+   ```python
+   except SomeError as e:
+       return Result(data=NIL_T, errors=[ErrorInfo(
+           category="<category>",
+           message=str(e),
+           source="<module>.<function>",
+           exception=e,
+       )])
+   ```
+   - If the function has a sensible fallback value (e.g., `default_value`), use `Result(data=default_value, errors=[...])` instead of `NIL_T`. The caller still sees the error in `.errors` and decides what to do.
+5. Update **all** callers to check `.ok` and `.errors`. No caller should ignore `.errors` silently.
+6. Add a test for the new Result-based API. Tests must cover:
+   - The success path: `assert result.ok and result.data == <expected>`
+   - The error path: `assert not result.ok and result.errors[0].category == <expected>`
+
+The migration is per-file. Group files into atomic commits. The 21 sites:
+
+#### 11.3.1: `src/warmup.py` (6 sites: 4 io_pool callbacks + 2 observability helpers)
+
+These are the most important. Tier-2's claim that "user callbacks cannot be Result-typed" is WRONG. The user callbacks in `WarmupManager._callbacks` are `Callable[[dict], None]` and stay as-is. The INTERNAL methods (`_record_success`, `_record_failure`, `_log_canary`, `_log_summary`) and the public methods (`on_complete`, `submit`, `wait`) are NOT user code - they are part of the manager and CAN return `Result[T]`. **Apply the same pattern tier-2 used in `src/hot_reloader.py`.**
+
+- [ ] **Task 11.3.1.1: Migrate `src/warmup.py:139` (`on_complete` callback fire) to `Result[T]`**
+  - WHERE: `src/warmup.py:on_complete()` method (around L139)
+  - WHAT: Change `on_complete()` to return `Result[bool]`. The callback wrapping (`try: callback(snap) except Exception as e: sys.stderr.write(...)`) becomes the wrapper. The internal `_callbacks` list contains user callbacks (`Callable[[dict], None]`); these stay as-is. The Result is for the manager's own bookkeeping.
+  - HOW: See `src/hot_reloader.py:reload()` for the pattern.
+  - COMMIT: `refactor(src): warmup.on_complete to Result[T] (io_pool callback thread-through)`
+  - GIT NOTE: Follows the same pattern as `src/hot_reloader.py:reload()` (the io_pool completion handler checks `result.ok`)
+
+- [ ] **Task 11.3.1.2: Migrate `src/warmup.py:215` (`_record_success` callback fire) to `Result[T]`**
+  - WHERE: `src/warmup.py:_record_success()` method
+  - WHAT: Change to return `Result[bool]`
+  - HOW: See `src/hot_reloader.py` pattern

+  - WHERE: `src/warmup.py:_log_canary()` method

+  - COMMIT: rolled into the per-method commits above
+
+#### 11.3.2: `src/startup_profiler.py:40` (the "context manager" lie)
+
+`StartupProfiler.phase()` is NOT a context manager. It is a regular method that returns `None`. There is no `__enter__` or `__exit__`. Tier-2's claim is factually wrong.
+
+- [ ] **Task 11.3.2.1: Migrate `src/startup_profiler.py:40` (`_end_phase` stderr.write) to `Result[T]`**
+  - WHERE: `src/startup_profiler.py:phase()` or `_end_phase()` method (around L40)

+  - COMMIT: `refactor(src): startup_profiler.phase/_end_phase to Result[T] (NOT a context manager; regular method)`
+  - GIT NOTE: Tier-2 claimed `phase()` was a context manager. It is not. It is a regular method that returns `None`. Changing to `Result[None]` is straightforward.

+
+## Phase 12: Result[T] PROPAGATION — REJECT Heuristic #19; Fix Audit Bug; Migrate ALL Hidden Violations
+
+**THE PRINCIPLE (the user, 2026-06-17, in CAPS):**
+> **"IF ANY PLACE HAS A ERROR LOG IT ALSO NEEDS A RESULT[T]. RESULT[T] PROPOGATES UNTIL IT REACHED A 'DRAIN' POINT WHERE THE ERROR CAN BE HANDLED APPROPRIATELY WITHOUT CRASHING THE APP. THE APP SHOULD ALMOST NEVER CRASH UNLESS SOMETHING CRITICAL FAILS THAT PREVENTS IT FROM ACTUALLY OPERATING WITH ITS FEATURES."**
+
+Phase 11 was REJECTED. The reasons are documented below. Phase 12 follows from the principle.
+
+**WHY PHASE 11 FAILED (3 root causes):**
+
+1. **Heuristic #19 is LAUNDERING.** The "narrow + log = compliant" heuristic that was added in the review pass (sub-track 1) is WRONG under the user's principle. Logging is NOT a drain. A function that catches and logs is still throwing away the error context. The principle says: **the function MUST return `Result[T]`, and the Result must propagate to a real drain point.** Heuristic #19 is removed in Phase 12.1.
+
+2. **The audit-script `visit_Try` walker is BUGGY.** It does NOT recurse into `node.body` (the try body itself). Only `handler.body`, `orelse`, and `finalbody` are recursed. This means nested Trys in the try body are silently dropped from the audit. I verified this against the actual code: `src/api_hooks.py` has 23 actual try/except nodes but the audit only reports 5 findings — a gap of 18 sites. At least 12 of those 18 are silent-fallback violations (`except Exception: payload = {...}` or `except Exception: var = fallback`). The bug is fixed in Phase 12.2.
+
+3. **Tier-2 misclassified sites that don't match the heuristic they claim.** Tier-2's Phase 11 report said `api_hooks.py:451` and `api_hooks.py:824` are "HTTP request handlers; classified `INTERNAL_COMPLIANT` via Heuristic #19". The actual code at L451 is `except (OSError, ValueError) as e: self.send_response(500)` (narrow + HTTP response, NOT a Heuristic #19 log call). The actual code at L824 is `except (OSError, ValueError) as e: import traceback; traceback.print_exc(file=sys.stderr)` (narrow + traceback, NOT a Heuristic #19 log call). Both sites are in scope for Phase 12 migration.
+
+**WHAT IS A DRAIN POINT (the only legitimate exception to the Result[T] requirement):**
+
+A drain point is a function that **HANDLES** the error such that the app does not crash. Per the user's principle:
+- The app should almost never crash.
+- A drain point is where the error is HANDLED — shown to the user, used to make a decision, or causes intentional app termination.
+- Examples of LEGITIMATE drain points:
+  - `try: ...; except: imgui.text(f"Error: {e}"); return` (user-visible error in GUI)
+  - `try: ...; except: self.send_response(500); self.wfile.write(json.dumps({"error": ...}))` (HTTP error response)
+  - `try: ...; except: sys.exit("Fatal: ...")` (intentional app termination with message)
+  - `try: ...; except: controller.show_error_modal(...)` (UI error modal)
+- Examples of NOT drain points (must be Result[T]):
+  - `try: ...; except: sys.stderr.write(...); pass` (just log)
+  - `try: ...; except: logger.error(...); return default` (just log + return default)
+  - `try: ...; except: print(...)` (just print)
+  - `try: ...; except: pass` (silent)
+  - `try: ...; except SomeError: var = fallback` (silent fallback)
+
+The audit's Heuristic D (new in Phase 12) recognizes the SMALL set of legitimate drain-point patterns. Everything else must return `Result[T]`.
+
+**PHASE 12 SCOPE:**
+
+- 1 audit-script bug fix (visit_Try recurses into node.body)
+- 1 heuristic removal (Heuristic #19) + corresponding test changes
+- 1 heuristic addition (Heuristic D: True Drain-Point Recognition) with TDD
+- Re-audit of 37-file scope + the 3 refactored baseline files
+- Per-file migration of ALL newly-revealed violations to `Result[T]`
+- Caller updates for every migrated function
+- Test updates for every migration
+- Verification: ALL 11 test tiers PASS (not 10; not 9)
+
+The migration will likely surface **20-50+ additional sites** beyond Phase 11's count. The scope is the migration of every such site to `Result[T]`, with the small set of true drain points exempted via Heuristic D.
+
+---
+
+### 12.0 — TIER-2 MUST READ `error_handling.md` (PREREQUISITE)
+
+**WHY:** Phase 12 follows the user's principle (Result[T] propagates to drain points; logging is NOT a drain). This principle is codified in `conductor/code_styleguides/error_handling.md`. Tier-2 MUST read the styleguide end-to-end BEFORE doing any Phase 12 work. Without this prerequisite, tier-2 will revert to idiomatic Python (`try/except` + `Optional[T]` + `raise Exception`) and reintroduce the exact problems Phase 12 is fixing.
+
+- **WHERE:** `conductor/code_styleguides/error_handling.md` (the canonical convention reference)
+- **WHAT:** Read the entire file. Specifically, the following sections are relevant to Phase 12:
+  - "The 5 Patterns" (lines 22-129) — the canonical Result[T] / ErrorInfo / nil-sentinel patterns
+  - "Decision Tree" (lines 152-171) — when to use Result vs nil-sentinel vs assert vs raise
+  - "Anti-Patterns" (lines 175-190) — the 6 forbidden patterns
+  - "Hard Rules" (lines 212-252) — the 3 non-negotiable rules in refactored files
+  - "Boundary Types" (lines 274-352) — the 3 boundary patterns (SDK, stdlib I/O, FastAPI)
+  - "The Broad-Except Distinction" (lines 356-411) — the canonical table that says `log only` is a violation
+  - "AI Agent Checklist" (lines 639-779) — the 5 MUST-DO and 7 MUST-NOT-DO rules
+- **HOW:** Open the file in your editor; read it. Confirm in the FIRST Phase 12 commit message: `"TIER-2 READ conductor/code_styleguides/error_handling.md before Phase 12.0.1."`
+- **NO CODE:** This is a READ task. No code changes. The acknowledgment is in the commit message of the next task.
+- **SAFETY:** The acknowledgment in the commit message is the audit trail. If tier-2 proceeds without reading, the styleguide-based reasoning in subsequent commits will be inconsistent.
+
+---
+
+### 12.0.1 — UPDATE `error_handling.md` to be aware of drain points
+
+**WHY:** The user's principle introduces a new concept — the **drain point** — that is not currently in the styleguide. The styleguide's "Boundary Types" section has 3 patterns (SDK, stdlib I/O, FastAPI HTTPException); these are **boundaries** (where exceptions originate or are converted). The user's "drain point" is different: it's where the error is **HANDLED** (not just converted or recorded). A drain point is the place where Result[T] propagation TERMINATES — the error is finally visible to the user or used to make a decision.
+
+Without updating the styleguide, the next agent will re-add Heuristic #19 (or its equivalent) because the styleguide's "narrow + log = violation" rule is IMPLICIT in the Broad-Except Distinction table, not EXPLICIT. Making it explicit in the styleguide prevents the regression.
+
+- **WHERE:** `conductor/code_styleguides/error_handling.md`
+- **WHAT:** Make 3 changes:
+
+  **(A) Add a "Drain Points" section** AFTER the "Boundary Types" section (around line 352). The section defines what a drain point is and lists the 5 recognized patterns:
+  - **HTTP error response** (`try: ...; except SomeError as e: self.send_response(<status>); self.wfile.write(json.dumps({"error": str(e)}))`) — the catch site delivers a user-visible HTTP error. The error is HANDLED at the HTTP boundary.
+  - **GUI error display** (`try: ...; except SomeError as e: imgui.text(f"Error: {e}")`) — the catch site displays the error to the user. The error is HANDLED in the GUI.
+  - **Intentional app termination** (`try: ...; except SomeError as e: sys.exit(f"Fatal: {e}")`) — the catch site terminates the app with a message. The error is HANDLED via the termination.
+  - **Telemetry emission** (`try: ...; except SomeError as e: telemetry.emit("error", ...)`) — the catch site emits a structured error event. The error is HANDLED via the data-oriented event record.
+  - **Retry-with-bounded-attempts** (`try: ...; except SomeError as e: if attempt < max: retry(); else: raise`) — the catch site retries with a bounded loop. The error is HANDLED within the retry envelope; if all retries fail, the error propagates.
+  
+  Each pattern has a code example (compliant) and a "NOT a drain" example (violation). The section explicitly states: **`sys.stderr.write(...)` alone is NOT a drain** — the error is recorded but not visible to the user and not used to make a decision; it's the data being lost. Logging alone requires the function to also return `Result[T]` so the caller can drain or propagate.
+
+  **(B) Update the "Broad-Except Distinction" table** (lines 358-370) to add an explicit row:
+  ```
+  | `narrow except + log (sys.stderr.write/logging.*) only | INTERNAL_SILENT_SWALLOW | **Violation** (the data is lost; logging is not a drain) |
+  ```
+  This makes the Heuristic #19 laundering IMPOSSIBLE — the styleguide explicitly forbids it.
+
+  **(C) Add to the AI Agent Checklist (MUST-DO)** a new top-level rule:
+  ```
+  0. **READ the styleguide FIRST.** Before writing or modifying any try/except code, READ `conductor/code_styleguides/error_handling.md` end-to-end. Acknowledge the read in the commit message. The styleguide is the source of truth; the AI's training data is the OPPOSITE of this convention.
+  ```
+
+- **HOW:** Use `manual-slop_edit_file` to make the 3 changes. The 3 changes are non-overlapping (different sections of the file). Verify with `py_check_syntax` on any other files affected. The styleguide is markdown, not Python, so syntax checks don't apply — just review the rendered output.
+- **SAFETY:** The 3 changes do not break the existing convention. They ADD a new section (A), MODIFY an existing table (B) to be more explicit, and ADD a new rule to the AI Agent Checklist (C). None of the existing rules are removed or contradicted.
+- **VERIFY:** Re-read the styleguide end-to-end. Confirm:
+  - The "Drain Points" section is present and has the 5 patterns with code examples
+  - The "Broad-Except Distinction" table has the new row about "narrow + log = violation"
+  - The AI Agent Checklist has the new "READ the styleguide FIRST" rule
+- **COMMIT:** `docs(styleguide): add Drain Points section; update Broad-Except table with explicit narrow+log violation; add MUST-READ rule to AI Agent Checklist`
+- **GIT NOTE:** "Phase 12.0.1. Per user directive 2026-06-17: 'make sure to update the style guide to be aware of the concept of a drain point, which just makes explicit a place where Result[T] doesn't apply because the error is being handled.' 3 changes: (A) Drain Points section with 5 patterns (HTTP error response, GUI error display, app termination, telemetry, retry-with-bounded-attempts); (B) Broad-Except Distinction table now EXPLICITLY says narrow+log=violation (prevents Heuristic #19 regression); (C) AI Agent Checklist adds MUST-READ rule."
+
+---
+
+### 12.1 — REMOVE Heuristic #19 (the laundering heuristic)
+
+**WHY:** Heuristic #19 is the "narrow + log = compliant" pattern. The user's principle: **logging is NOT a drain.** A function that catches and logs is throwing away the error context. The convention requires `Result[T]`, not `sys.stderr.write + return default`.
+
+- **WHERE:** `scripts/audit_exception_handling.py` `_try_compliant_pattern` method, around line 582 (the comment "19. Narrow except + log (sys.stderr.write or logging.*) for defer-not-catch or retry-then-give-up")
+- **WHAT:** Surgically delete the entire Heuristic #19 `if` block. Lines approximately 582-587 (the comment + the `if` body returning the tuple).
+- **HOW:** Use `manual-slop_edit_file` to delete the block. Verify with `py_check_syntax` after.
+- **SAFETY:** The block is a single return statement inside a chain of `if` blocks. The delete must preserve the chain's structure.
+- **COMMIT:** `revert(scripts): REMOVE Heuristic #19 (narrow+log laundering; logging is NOT a drain)`
+- **GIT NOTE:** "Heuristic #19 added in review pass; rejected by user 2026-06-17. Logging is not a drain point. Result[T] must propagate."
+
+**12.1.1 — Update the Heuristic #19 test**
+
+- **WHERE:** `tests/test_audit_exception_handling_heuristics.py` (the test for Heuristic #19)
+- **WHAT:** The existing test asserts that narrow + log is `INTERNAL_COMPLIANT`. After 12.1, the same input should be classified as a VIOLATION (`INTERNAL_SILENT_SWALLOW` or `INTERNAL_BROAD_CATCH` or `INTERNAL_OPTIONAL_RETURN`, depending on the body).
+- **HOW:** Update the test to assert the NEW expected category. Do NOT delete the test — the test still validates the audit's behavior; the expected category just changes.
+- **COMMIT:** Same commit as 12.1, or a follow-up.
+
+---
+
+### 12.2 — FIX the visit_Try audit-script bug (recurse into node.body)
+
+**WHY:** The current `visit_Try` recurses into `handler.body`, `orelse`, and `finalbody` but NOT `node.body` (the try body itself). This causes nested Trys in the try body to be silently dropped. I verified this: `src/api_hooks.py` has 23 actual try/except nodes but the audit only reports 5 findings (gap of 18 sites, 12+ of which are silent-fallback violations).
+
+- **WHERE:** `scripts/audit_exception_handling.py` `ExceptionVisitor.visit_Try` method, around line 848
+- **WHAT:** Add `for child in node.body: self.visit(child)` to recurse into the try body. Place it BEFORE the handlers loop (or at the top, so nested Trys are visited first).
+- **HOW:** Use `manual-slop_edit_file` to insert the 2 lines. The current code is:
+  ```python
+  def visit_Try(self, node: ast.Try) -> None:
+   self._try_stack.append(node)
+   try:
+    # bare try/finally (no except) = canonical cleanup pattern
+    if not node.handlers and node.finalbody:
+     self._add_finding(
+      "TRY",
+      node.lineno,
+      self._snippet(node),
+      "INTERNAL_COMPLIANT",
+      "Compliant: bare try/finally is the canonical cleanup pattern (analog of `goto defer`).",
+     )
+    for handler in node.handlers:
+     category, hint = self._classify_except(handler, node)
+     ...
+  ```
+  Insert `for child in node.body: self.visit(child)` after the bare try/finally check and before the handlers loop.
+- **SAFETY:** The new recursion is additive — it only ADDS findings, never removes them. Existing 5 findings in `api_hooks.py` will still appear; new findings for nested Trys will also appear.
+- **VERIFY:** After the fix, run the audit on `src/api_hooks.py` and confirm the count is 23 (or 23 + the raise statements = ~25), not 5.
+- **COMMIT:** `fix(scripts): visit_Try recurses into node.body (fix nested-Try audit gap)`
+- **GIT NOTE:** "audit bug: visit_Try did not recurse into try body. Nested Trys were silently missed. Example: api_hooks.py has 23 actual try/except nodes but the audit reported only 5. Gap: 18 sites. Fix: add 2 lines to visit_Try."
+
+**12.2.1 — Write a TDD test for the visit_Try fix**
+
+- **WHERE:** `tests/test_audit_exception_handling_bug_fixes.py` (extend the existing file)
+- **WHAT:** Write a test that constructs a Python source string with a nested Try (an outer try with a try/except inside the try body) and asserts that the audit finds BOTH the outer and the inner except handlers.
+- **HOW:** Use `audit_file(Path(test_file))` after writing the source to a temp file; assert the number of EXCEPT findings equals the expected count.
+- **COMMIT:** `test(scripts): TDD for visit_Try recursing into node.body`
+
+---
+
+### 12.3 — ADD Heuristic D (True Drain-Point Recognition) with TDD
+
+**WHY:** The convention allows a small set of LEGITIMATE drain points where the error is HANDLED. Heuristic D recognizes these so the audit doesn't flag them as violations. This is the REPLACEMENT for Heuristic #19.
+
+**Drain-point patterns Heuristic D recognizes (TDD-first; the test suite defines the patterns):**
+
+1. **HTTP error response:** `try: ...; except SomeError as e: self.send_response(<status>); self.wfile.write(<error_json>)` — the catch delivers a user-visible HTTP error response. Pattern: `send_response` or `send_error` call in the except body.
+2. **GUI error display:** `try: ...; except SomeError as e: imgui.text(f"Error: {e}"); imgui.pop_style_color()` — the catch displays the error to the user. Pattern: `imgui.text` or `imgui.text_colored` with the error string in the except body.
+3. **Intentional app termination:** `try: ...; except SomeError as e: sys.exit(<message>)` or `raise SystemExit(<message>)` — the catch terminates the app with a message. Pattern: `sys.exit` or `raise SystemExit` in the except body.
+4. **Telemetry emission:** `try: ...; except SomeError as e: telemetry.emit("error", ...)` — the catch emits a structured error event. Pattern: call to a `telemetry.*` or `audit.*` or `events.emit` method.
+5. **Retry with bounded attempts:** `try: ...; except SomeError as e: if attempt < max: retry(); else: raise` — the catch retries with a bounded loop. Pattern: `if attempt < max_retries:` followed by `continue` or `retry()`, then the catch's last line is `raise` or `return error_state`.
+
+- **WHERE:** `scripts/audit_exception_handling.py` `_try_compliant_pattern` method
+- **WHAT:** Add Heuristic D's `if` blocks AFTER Heuristic A (Result-returning recovery). Each pattern has its own `if` block with the matching condition and a hint.
+- **HOW:** TDD. Write the tests first (12.3.1, 12.3.2, etc.). Then implement the heuristic.
+- **COMMIT:** `feat(scripts): Heuristic D (True Drain-Point Recognition) — 5 patterns, TDD`
+- **GIT NOTE:** "Heuristic D replaces Heuristic #19. Logging is NOT a drain; only HANDLED errors are. 5 specific patterns: HTTP response, GUI display, app termination, telemetry, retry-with-bounded-attempts. TDD; each pattern has a passing test."
+
+**12.3.1 — TDD test for HTTP error response pattern**
+**12.3.2 — TDD test for GUI error display pattern**
+**12.3.3 — TDD test for intentional app termination pattern**
+**12.3.4 — TDD test for telemetry emission pattern**
+**12.3.5 — TDD test for retry-with-bounded-attempts pattern**

+### 12.4 — Re-run audit; capture post-fix findings
+
+- **WHERE:** Project root
+- **WHAT:** Run `uv run python scripts/audit_exception_handling.py --json --src src --include-baseline > docs/reports/PHASE12_AUDIT_POST_FIX_20260617.json`
+- **HOW:** Standard audit invocation. Save the JSON to the docs/reports/ directory.
+- **VERIFY:** The total violation count is now HIGHER than the pre-Phase-12 count (the bug fix + heuristic removal expose new sites).
+- **COMMIT:** `chore(audit): capture post-Phase-12-fix audit (visit_Try + Heuristic #19 removed + Heuristic D added)`
+- **GIT NOTE:** "Phase 12 audit capture. Count delta vs pre-Phase-12: +N violations (visit_Try fix); +M violations (Heuristic #19 removed); -K (Heuristic D exempts drain points)."

+
+### 12.5 — Triage the post-fix findings; build per-file action list
+
+- **WHERE:** `docs/reports/PHASE12_TRIAGE_20260617.md`
+- **WHAT:** Parse the post-fix JSON. For each violation (V or S category), record: file, line, function name, current pattern, target migration (what the Result[T] version looks like). Group by file. Save the triage as a markdown table.
+- **HOW:** A small Python script (`scripts/tier2/artifacts/result_migration_small_files_20260617/triage_phase12.py`) reads the JSON, groups by file, and emits markdown. Run the script; check the output.
+- **COMMIT:** `docs(report): Phase 12 triage — per-file action list for migration`
+- **GIT NOTE:** "Phase 12 triage: N sites to migrate, grouped by file. The migration is broken into sub-batches per file."
+
+---
+
+### 12.6 — Per-file migration to Result[T] (the bulk of Phase 12)
+
+For each file in the Phase 12 triage, do the migration. The pattern is the same as Phase 3-8:
+1. Identify the function/method
+2. Add `Result[T]` to the return type
+3. Add `from src.result_types import Result, ErrorInfo, ErrorKind` (if not present)
+4. Change the `except` body to `return Result(data=<default>, errors=[ErrorInfo(kind=ErrorKind.INTERNAL, message=str(e), source=<file>:<func>, original=e)])`
+5. Update the function's `return <value>` (success path) to `return Result(data=<value>)`
+6. Update callers to check `result.ok` and use `result.data` or `result.errors`
+
+**The triage table from 12.5 lists every file:line. Each file's migration is its own task with its own commit.**
+
+**12.6.1 — `src/api_hooks.py` migration (12+ sites)**
+- Sites: L294, L387, L410, L428, L442, L561, L592, L620, L719, L739, L793, L810 (and the L912 inner try that the audit DOES see)
+- WHAT: Each `except Exception: var = fallback` becomes `return Result(data=fallback, errors=[ErrorInfo(...)])` in a function that now returns `Result[T]`.
+- HOW: For each site, change the enclosing function's signature to `-> Result[T]`, change the except body to return a `Result` with `errors=[ErrorInfo]`, and update the function's success-path returns to wrap in `Result(data=...)`.
+- CALLER UPDATES: `_get_app_attr` callers in api_hooks.py and `api_hook_client.py` (the test client); `do_GET` / `do_POST` call sites.
+- COMMIT: `refactor(src): api_hooks.py Phase 12 - 12+ sites full Result[T] migration`
+- TESTS: 12.8.x
+- **KNOWN EXEMPTION:** L451, L824, L914 are HTTP response patterns. Heuristic D (HTTP error response) exempts them. Document in the per-site report.
+
+**12.6.2 — `src/warmup.py` Phase 12 verification (5 sites already migrated in Phase 11; verify Heuristic A recognizes them)**
+- Sites: L139, L215, L249, L276, L300, L185
+- WHAT: After Heuristic #19 is removed and Heuristic D is added, verify the audit still classifies these as INTERNAL_COMPLIANT (via Heuristic A — they return `Result(data=..., errors=[...])`).
+- HOW: Re-run the audit. The 5 sites should be INTERNAL_COMPLIANT via Heuristic A. The L185 io_pool callback (indirect return) is a known audit limitation (the audit's Heuristic A only matches direct `return Result(...)`; L185 returns `self._record_failure(...)` which returns Result). Document the limitation in the report; this is acceptable (the convention is followed; the audit has a limitation).
+- COMMIT: `chore(audit): verify warmup.py Phase 12 — Heuristic A recognizes the 5 sites`
+- GIT NOTE: "Phase 12 verification: warmup.py sites still INTERNAL_COMPLIANT via Heuristic A. L185 indirect return is a known audit limitation; convention is followed."
+
+**12.6.3 — `src/startup_profiler.py` Phase 12 verification**
+- Sites: L17 (_log_phase_output), L49 (phase())
+- WHAT: Verify the helper extraction is still recognized as INTERNAL_COMPLIANT via Heuristic A. The context manager exception is documented.
+- HOW: Re-run the audit.
+- COMMIT: `chore(audit): verify startup_profiler.py Phase 12`
+
+**12.6.4 — `src/file_cache.py` Phase 12 verification**
+- Sites: L48 (_get_mtime_safe)
+- WHAT: Verify the helper extraction is INTERNAL_COMPLIANT via Heuristic A.
+- HOW: Re-run the audit.
+- COMMIT: `chore(audit): verify file_cache.py Phase 12`
+
+**12.6.5 — `src/orchestrator_pm.py` Phase 12 verification (already Result[str])**
+- Sites: L11 (function signature), L33, L42
+- WHAT: Verify the function is still classified as BOUNDARY_CONVERSION (per-item ErrorInfo pattern).
+- HOW: Re-run the audit.
+- COMMIT: `chore(audit): verify orchestrator_pm.py Phase 12`
+
+**12.6.6 — `src/project_manager.py` Phase 12 verification (already BOUNDARY_CONVERSION)**
+- Sites: L372, L384, L399
+- WHAT: Verify the per-item ErrorInfo pattern is still BOUNDARY_CONVERSION.
+- HOW: Re-run the audit.
+- COMMIT: `chore(audit): verify project_manager.py Phase 12`
+
+**12.6.7 — `src/log_registry.py` Phase 12 migration (4 sites)**
+- Sites: L97, L135, L250, L294
+- WHAT:
+  - L97 (`except Exception as e: print(f'Error loading registry from...')`): Heuristic D does NOT match (print is not a drain). Migrate to `Result[T]`.
+  - L135: already returns `Result(data=False, errors=[ErrorInfo(...)])`. Verify Heuristic A recognizes it.
+  - L250: Heuristic #19 used to match. Now Heuristic #19 is removed. The site is `except OSError as e: sys.stderr.write(...)`. Per the principle, logging is NOT a drain. **Migrate to `Result[T]`.** The except body becomes `return Result(data=default, errors=[ErrorInfo(kind=ErrorKind.INTERNAL, message=str(e), source=..., original=e)])`. The function signature changes to `-> Result[T]`.
+  - L294: `except ValueError: start_time = None` — silent fallback. Migrate to `Result[T]`.
+- HOW: For L250, change the function signature, change the except body, update callers. For L97 and L294, similar.
+- CALLER UPDATES: scan with `py_find_usages`.
+- COMMIT: `refactor(src): log_registry.py Phase 12 - 4 sites full Result[T] migration`
+- TESTS: 12.8.x
+
+**12.6.8 — `src/models.py` Phase 12 migration (3 sites)**
+- Sites: L452, L457, L508
+- WHAT: All three are `except ValueError: var = None` or `except ValueError as e: sys.stderr.write(...)`. Per the principle, none of these are drain points. Migrate all three to `Result[T]`.
+- HOW: For each, change the enclosing function's signature, change the except body, update callers.
+- CALLER UPDATES: `TrackState.from_dict` callers (lots; use `py_find_usages`).
+- COMMIT: `refactor(src): models.py Phase 12 - 3 sites full Result[T] migration`
+- TESTS: 12.8.x
+
+**12.6.9 — `src/multi_agent_conductor.py` Phase 12 migration (4 sites)**
+- Sites: L234, L236, L317, L468, L636
+- WHAT: All five are `except SpecificError: print(...)` or `except SpecificError: sys.stderr.write(...)`. Per the principle, none are drain points. Migrate all to `Result[T]`.
+- HOW: For each, change the enclosing function's signature, change the except body, update callers.
+- CALLER UPDATES: scan with `py_find_usages`. The WorkerPool and conductor engine are the main callers.
+- COMMIT: `refactor(src): multi_agent_conductor.py Phase 12 - 4 sites full Result[T] migration`

+
+**12.6.10 — `src/theme_2.py` Phase 12 migration (1 site)**
+- Sites: L282
+- WHAT: `except (ImportError, AttributeError) as e: sys.stderr.write(...)`. Migrate to `Result[T]`.
+- HOW: Change the enclosing function's signature, change the except body, update callers.
+- CALLER UPDATES: `apply()` callers (theme switching in gui_2.py).
+- COMMIT: `refactor(src): theme_2.py Phase 12 - 1 site full Result[T] migration`
+- TESTS: 12.8.x
+
+**12.6.11 — `src/shell_runner.py` Phase 12 migration (Tier 4 QA error interception)**
+- Sites: 2-3 sites per the audit
+- WHAT: Migrate to `Result[T]` (Tier 4 QA may have legitimate drain points — verify with Heuristic D).
+- HOW: Same pattern.
+- CALLER UPDATES: shell_runner.py callers in `mcp_client.py` (the tool execution path).
+- COMMIT: `refactor(src): shell_runner.py Phase 12 - N sites full Result[T] migration`
+- TESTS: 12.8.x
+
+**12.6.12 — `src/session_logger.py` Phase 12 migration (4 sites)**
+- Sites: per the audit (likely 4 SILENT_SWALLOW sites from the audit summary)
+- WHAT: Migrate to `Result[T]`.
+- HOW: Same pattern.
+- CALLER UPDATES: session logger is called from many places.
+- COMMIT: `refactor(src): session_logger.py Phase 12 - 4 sites full Result[T] migration`
+- TESTS: 12.8.x
+
+**12.6.13 — Other SMALL files (triage-driven)**
+- For every file in the Phase 12 triage, do the migration. The triage (12.5) lists every site.
+- Each file gets its own commit.
+
+---
+
+### 12.7 — Update callers of all migrated functions
+
+- **WHERE:** Every caller of the migrated functions in 12.6.x
+- **WHAT:** For each caller, change the call from `result = func()` + `if result:` to `result = func()` + `if not result.ok: ...` + `use(result.data)`. The `data` field carries the value; the `errors` field carries the ErrorInfo.
+- **HOW:** For each migration in 12.6.x, use `manual-slop_py_find_usages` to find all callers. Update each caller to check `result.ok` and use `result.data` or `result.errors`.
+- **SAFETY:** The `data` field's type matches the original function's return type. The `errors` field is a `list[ErrorInfo]`. If the caller previously checked the return value for None, check `result.ok` instead.
+- **COMMIT:** Bundled with the per-file migration in 12.6.x.
+
+---
+
+### 12.8 — Update tests for every migration
+
+- **WHERE:** `tests/` directory
+- **WHAT:** For each migration, update the test(s) to handle the new `Result[T]` return type. Tests that assert on the old return value now assert on `result.data` (or `result.ok` and `result.errors`).
+- **HOW:** Use `manual-slop_py_find_usages` on the migrated function. For each test, update the assertions.
+- **TESTS TO ADD:** For each migration, add at least 1 test for the error path:
+  ```python
+  def test_<func>_error_path(self):
+   result = <func>(<bad_input>)
+   assert not result.ok
+   assert result.errors[0].category == ErrorKind.INTERNAL
+   assert result.errors[0].message  # non-empty
+  ```
+- **COMMIT:** Bundled with the per-file migration in 12.6.x.
+
+---
+
+### 12.9 — Run all 11 test tiers; verify 11/11 PASS
+
+- **WHERE:** Project root
+- **WHAT:** Run `uv run python scripts/run_tests_batched.py` and confirm all 11 tiers PASS.
+- **HOW:** Standard batched runner. The 11 tiers are: tier-1-unit-comms, tier-1-unit-core, tier-1-unit-gui, tier-1-unit-headless, tier-1-unit-mma, tier-2-mock_app-comms, tier-2-mock_app-core, tier-2-mock_app-gui, tier-2-mock_app-headless, tier-2-mock_app-mma, tier-3-live_gui.
+- **VERIFY:** All 11 PASS. If any tier fails, the migration is incomplete; fix the regression before marking Phase 12 complete.
+- **COMMIT:** (no commit — just verification)
+- **TEST_COUNT_CLAIM:** The number of test tiers is 11, not 10. This is the FOURTH time this is being emphasized. If the report says 10, it is wrong.
+
+---
+
+### 12.10 — Update the per-site report and the track completion report
+
+- **WHERE:** `docs/reports/RESULT_MIGRATION_SMALL_FILES_20260617.md` (per-site) + `docs/reports/TRACK_COMPLETION_result_migration_small_files_20260617.md` (completion)
+- **WHAT:** Add a "Phase 12" section that:
+  - REJECTS Phase 11 (Phase 11 was REJECTED because it left Heuristic #19 in place; the user's principle says logging is NOT a drain; also Phase 11 missed the visit_Try bug)
+  - Documents Phase 12: Heuristic #19 removed, visit_Try fixed, Heuristic D added, N new sites migrated
+  - Per-site decisions: which sites were drained (HTTP response, GUI display, app termination) vs Result-typed
+  - Test pass count: ALL 11 TIERS PASS
+- **COMMIT:** `docs(reports): Phase 12 addendum — Heuristic #19 removed; visit_Try fixed; Heuristic D added; N sites migrated`
+- **GIT NOTE:** "Phase 12 addendum. The 4th redo of the small-files Result[T] migration. The user's principle: Result[T] propagates until a drain point. Logging is not a drain. ALL 11 test tiers PASS."
+
+---
+
+### 12.11 — Mark Phase 12 complete
+
+- **WHERE:** `conductor/tracks/result_migration_small_files_20260617/state.toml` + `metadata.json` + `conductor/tracks.md`
+- **WHAT:**
+  - state.toml: mark all Phase 12 tasks completed with commit SHAs; update `status: active → completed`; `current_phase: 12 → "complete"`
+  - metadata.json: add Phase 12 outcomes (heuristics_removed=1, heuristics_added=1, audit_bug_fixes=1, sites_migrated_phase_12=N, total_sites_migrated=49+N, total_sites_compliant=...)
+  - tracks.md: update the sub-track 2 row to reflect Phase 12 completion
+- **COMMIT:** `conductor(track): mark result_migration_small_files_20260617 Phase 12 complete (Heuristic #19 removed; visit_Try fixed; Heuristic D added; N sites Result-typed; 11/11 test tiers PASS)`
+- **GIT NOTE:** "Phase 12 is the ACTUAL completion. Phase 10 was REJECTED. Phase 11 was REJECTED. Phase 12 follows the user's principle: Result[T] propagates to drain points. Heuristic #19 was laundering. visit_Try was buggy. Both fixed."
+
+---
+
+### 12.12 — Update the umbrella spec
+
+- **WHERE:** `conductor/tracks/result_migration_20260616/spec.md`
+- **WHAT:** Update the post-sub-track-2 callout:
+  - Replace "Phase 11 in progress" with "Phase 12 COMPLETE; the user's principle: Result[T] propagates to drain points. Heuristic #19 removed; visit_Try fixed; Heuristic D added; N sites Result-typed; 11/11 test tiers PASS."
+  - Add a "Phase 12 Update" callout with the principle and the per-site counts.
+- **COMMIT:** `docs(track): update umbrella with sub-track 2 Phase 12 complete (REAL completion; drain-point principle)`
+- **GIT NOTE:** "Phase 12 is the actual completion. The drain-point principle. 11/11 test tiers PASS."
+
+---
+
+### 12.13 — Conductor - User Manual Verification
+
+Per workflow.md: User manually verifies the per-file migrations, the per-file Result[T] returns, the test pass count, and the report's claims about which sites are drained vs Result-typed. The user confirms Phase 12 is complete (or identifies remaining issues).
+
+---
+
+## Phase 13: Test Count Verification — Fix the Script Crash; Re-Run All 11 Tiers; Verify the 3 "Pre-Existing" Failures
+
+**WHY Phase 12 is REJECTED (3 reasons, all about the test claim):**
+
+1. **Tier-2 marked Phase 12 complete based on incomplete test results.** The test runner script `scripts/run_tests_batched.py:185` crashed on a `UnicodeEncodeError` after running only **5 of 11 tiers**. The remaining 6 tiers (tier-2-mock-comms/core/gui/headless/mma + tier-3-live_gui) were NOT executed. Tier-2's completion commit (`2235e4b8`) falsely claims "11 tiers total. 10 PASS" — the actual count is 5 tested, 4 passed, 1 failed, 6 not tested.
+
+2. **The 3 "pre-existing failures" in tier-1-unit-core are not all pre-existing:**
+   - `test_gemini_provider_passes_qa_callback_to_run_script` — mock assertion failure. The test expects `_run_script` to be called with `(script, ".", qa_callback, None)` but the mock says "not called." This is **NOT** a Gemini API 503; this is a real test failure that may be a regression from Phase 12.
+   - `test_auto_aggregate_skip` and `test_view_mode_summary` — Gemini API 503 (network-dependent). These MIGHT be pre-existing but tier-2's "verified via git stash" claim is unverified (no parent-commit run is documented in the test log).
+
+3. **The user's directive has been emphatic across multiple sessions:** **ALL 11 test tiers must PASS. The test count is 11, not 10.** Tier-2 has been miscounting in every prior phase (10, 11, 10+1-fail, now 10-PASS). The 5th time this is being emphasized: **11 tiers, 11 PASS, no script crash, no "pre-existing" excuse without parent-commit verification.**
+
+**The migrations and audit/styleguide work in Phase 12 are real and substantial:**
+- 16 sites in `src/api_hooks.py` migrated to `Result[T]` (3 helpers extracted)
+- 27 sites in 16 small files migrated to `Result[T]`
+- `src/api_hooks.py` audit post-fix: 0 violations, 0 UNCLEAR
+- Sub-track 2 scope audit post-fix: 0 violations, 0 UNCLEAR
+
+**The work IS real. The test claim is NOT.** Phase 12's migrations stand; Phase 12's test verification must be re-done.
+
+---
+
+### 13.1 — FIX the script crash in `scripts/run_tests_batched.py`
+
+**WHY:** The test runner crashed at line 185 with `UnicodeEncodeError: 'charmap' codec can't encode characters in position 0-53: character maps to <undefined>`. The crash prevented tier-2-mock-comms/core/gui/headless/mma and tier-3-live_gui from being run. Without this fix, the test suite CANNOT run to completion.
+
+- **WHERE:** `scripts/run_tests_batched.py:185` (the `_print_summary` function, the line that prints the summary table)
+- **WHAT:** The `_print_summary` function prints tier names that may contain non-ASCII characters (e.g., the box-drawing characters in the summary table separator). The default Windows console encoding (cp1252) cannot encode these characters. Fix by either:
+  - **Option A (preferred):** Configure stdout to use UTF-8: `sys.stdout.reconfigure(encoding='utf-8', errors='replace')` at the start of the script. This preserves the unicode characters in the output.
+  - **Option B:** Replace non-ASCII characters with ASCII equivalents in the summary table (e.g., `─` → `-`, `│` → `|`).
+  - **Option C:** Use `print(..., flush=True)` and wrap the printing in a try/except that falls back to ASCII on encoding errors.
+- **HOW:** Use `manual-slop_edit_file` to make the change. Add `sys.stdout.reconfigure(encoding='utf-8', errors='replace')` at the top of the `main()` function (after the imports). Verify by running the script and confirming the summary table prints without error.
+- **SAFETY:** The reconfigure call is safe on all platforms. On Linux/macOS, stdout is already UTF-8 by default; the reconfigure is a no-op. On Windows, the reconfigure enables UTF-8 output.
+- **VERIFY:** Run `uv run python scripts/run_tests_batched.py` and confirm the script completes without crashing (all 11 tiers run, even if some fail).
+- **COMMIT:** `fix(scripts): run_tests_batched.py stdout UTF-8 (fix UnicodeEncodeError crash at line 185)`
+- **GIT NOTE:** "Phase 13.1. The test runner script crashed on UnicodeEncodeError at line 185 (the summary table print). Without this fix, the test suite cannot run to completion. Fix: sys.stdout.reconfigure(encoding='utf-8', errors='replace') at the start of main(). This is the FIRST action of Phase 13 — without it, no other test verification is possible."
+
+---
+
+### 13.2 — INVESTIGATE the 3 tier-1-unit-core failures on the PARENT commit
+
+**WHY:** Tier-2 claimed the 3 failures are "pre-existing" but did NOT verify by running on the parent commit. The user has been emphatic that "pre-existing" claims must be backed by evidence, not assertions. **At least one of the 3 (the mock assertion) is NOT a Gemini API 503** — it's a real test failure that may be a Phase 12 regression.
+
+- **WHERE:** Run tests on the parent commit of `2235e4b8` (Phase 12 completion). The parent is `4ab7c732` (Phase 12.6.2-12.6.13).
+- **WHAT:** For each of the 3 failing tests, run on the parent commit:
+  ```bash
+  # From the working tree (currently on 2235e4b8):
+  git stash
+  git checkout 4ab7c732
+  uv run pytest tests/test_tier4_interceptor.py::test_gemini_provider_passes_qa_callback_to_run_script -x
+  uv run pytest tests/test_aggregate_flags.py::test_auto_aggregate_skip -x
+  uv run pytest tests/test_context_composition_phase6.py::test_view_mode_summary -x
+  # Then return to the current commit
+  git checkout 2235e4b8
+  git stash pop
+  ```
+  Record the results:
+  - If a test PASSES on the parent commit: it IS a regression. Document and fix.
+  - If a test FAILS on the parent commit: it IS pre-existing. Document the parent commit hash and the failure.
+- **HOW:** Use `git checkout` and `git stash` to temporarily switch commits. Run each test. Capture the output to a log file under `tests/artifacts/PHASE13_PARENT_COMMIT_RESULTS.log`.
+- **SAFETY:** **HARD BAN on `git restore` and `git checkout -- <file>`** per AGENTS.md. Use `git checkout <commit>` (the whole commit, not a file path) and `git checkout <branch>` to return. The `git stash` is for working-tree changes only; do not use `git stash` to "peek at baseline" of the previous agent's work.
+- **COMMIT:** `chore(audit): Phase 13.2 - run 3 failing tests on parent commit; record pre-existing vs regression`
+- **GIT NOTE:** "Phase 13.2 results: [PASS/FAIL for each of the 3 tests on parent commit 4ab7c732]. Regression sites: [list]. Pre-existing failures: [list]."
+
+---
+
+### 13.3 — FIX any actual regressions
+
+**WHY:** If any of the 3 failures is a Phase 12 regression (i.e., the test PASSES on the parent commit but FAILS on the current commit), the production code must be fixed. The user has been emphatic that regressions must be fixed, not papered over with `@pytest.mark.skip` or "pre-existing" excuses.
+
+- **WHERE:** Whatever production code caused the regression. The most likely candidates based on the test names:
+  - `test_gemini_provider_passes_qa_callback_to_run_script` — checks `src/ai_client.py:_send_gemini` calls `_run_script` with `(script, ".", qa_callback, None)`. If Phase 12 changed `_send_gemini`, this test will fail. Investigate by reading `_send_gemini` in `src/ai_client.py` and comparing to the test's expectation.
+  - `test_auto_aggregate_skip` — checks `src/aggregate.py:build_tier3_context` works with `auto_aggregate=False`. If Phase 12 changed `aggregate.py`, this test will fail. Read the file.
+  - `test_view_mode_summary` — same as above (aggregate.py).
+- **WHAT:** Restore the correct behavior. Use `manual-slop_py_get_definition` to read the function, then use `manual-slop_edit_file` to fix the regression.
+- **HOW:** For each regression identified in 13.2, find the changed code (compare parent commit to current), identify the regression, and fix it. Add a TDD test if the regression isn't already covered.
+- **SAFETY:** The fix must not break the Phase 12 migrations (the audit's 0 violations in sub-track 2 scope). Verify by running the audit after the fix.
+- **COMMIT:** `fix(src): Phase 13.3 - restore [function name] behavior (regression from Phase 12)`
+- **GIT NOTE:** "Phase 13.3. Regressions introduced by Phase 12: [list]. Fixed in this commit. The audit's 0 violations in sub-track 2 scope is preserved."
+
+---
+
+### 13.4 — DOCUMENT the pre-existing failures (if any)
+
+**WHY:** If 13.2 finds that one or more of the 3 failures is pre-existing (passes on current commit, fails on parent), the failure must be documented honestly. Per AGENTS.md, `@pytest.mark.skip` is documentation of a known failure, not an excuse to AVOID fixing it. If the test is a legitimate pre-existing failure (e.g., the test depends on a live API that may be down), document it with `@pytest.mark.skip(reason=...)` AND a git note explaining the underlying issue.
+
+- **WHERE:** The test file with the pre-existing failure.
+- **WHAT:** Add `@pytest.mark.skip(reason="...")` to the test, with a reason that:
+  1. Documents the underlying issue (e.g., "this test depends on the live Gemini API which is currently rate-limited")
+  2. States what the fix would be (e.g., "the test should be mocked to not depend on the live API")
+  3. Commits with a follow-up note in the commit body
+- **HOW:** Use `manual-slop_edit_file` to add the skip marker. The reason must be specific and honest.
+- **SAFETY:** Do NOT add a skip marker for a regression. Only for a confirmed pre-existing failure.
+- **COMMIT:** `chore(tests): Phase 13.4 - mark pre-existing failure as @pytest.mark.skip with documentation`
+- **GIT NOTE:** "Phase 13.4. Pre-existing failure: [test name]. Reason: [why it fails]. Fix: [what would fix it]. Per AGENTS.md skip-marker policy: documentation of a known failure, not an excuse."
+
+---
+
+### 13.5 — RE-RUN all 11 test tiers; verify the script completes and 11/11 PASS
+
+**WHY:** Phase 12's "11 tiers total. 10 PASS" claim was wrong because the script crashed at 5/11. Phase 13 must actually run all 11 tiers and confirm 11/11 PASS (or 11/11 with skips, where the skips are documented pre-existing failures).
+
+- **WHERE:** Project root
+- **WHAT:** `uv run python scripts/run_tests_batched.py` and confirm the script completes without crashing. Confirm 11/11 tiers are reported in the output.
+- **HOW:** The script must run all 11 tiers to completion. The expected output is:
+  ```
+  <<< tier-1-unit-comms PASS in    <X>s
+  <<< tier-1-unit-core  PASS in    <X>s
+  <<< tier-1-unit-gui   PASS in    <X>s
+  <<< tier-1-unit-headless PASS in    <X>s
+  <<< tier-1-unit-mma   PASS in    <X>s
+  <<< tier-2-mock-comms  PASS in    <X>s
+  <<< tier-2-mock-core   PASS in    <X>s
+  <<< tier-2-mock-gui    PASS in    <X>s
+  <<< tier-2-mock-headless PASS in    <X>s
+  <<< tier-2-mock-mma    PASS in    <X>s
+  <<< tier-3-live_gui   PASS in    <X>s
+  ```
+  All 11 must show PASS. The summary table at the end must show 11/11 PASS.
+- **VERIFY:** The output contains all 11 `<<<` lines and the script exits 0.
+- **COMMIT:** (no commit — just verification)
+- **TEST_COUNT_CLAIM:** The number of test tiers is 11, not 10, not 9, not "10 + 1 fail". This is the **FIFTH TIME** this is being emphasized. If the report says 10, it is wrong.
+
+---
+
+### 13.6 — UPDATE the per-site report and completion report
+
+**WHY:** Phase 12's completion report (`docs/reports/TRACK_COMPLETION_result_migration_small_files_20260617.md`) and per-site report (`docs/reports/RESULT_MIGRATION_SMALL_FILES_20260617.md`) contain the false "11 tiers total. 10 PASS" claim. These must be updated to reflect Phase 13's actual test results.
+
+- **WHERE:**
+  - `docs/reports/RESULT_MIGRATION_SMALL_FILES_20260617.md` (per-site report)
+  - `docs/reports/TRACK_COMPLETION_result_migration_small_files_20260617.md` (track completion report)
+- **WHAT:** Add a "Phase 13" section that:
+  - REJECTS Phase 12's "10 PASS" claim as wrong
+  - Documents the script crash fix (13.1)
+  - Documents the 3-failure investigation (13.2) — pre-existing vs regression
+  - Documents the regression fixes (13.3) if any
+  - Documents the pre-existing failure skips (13.4) if any
+  - States the final test pass count: 11/11 PASS (or 10/11 PASS + 1 skipped, with the skip documented)
+- **COMMIT:** `docs(reports): Phase 13 addendum — script crash fix; 3-failure investigation; 11/11 tiers actually verified`
+- **GIT NOTE:** "Phase 13 addendum. The '10 PASS' claim in Phase 12 was wrong: the script crashed at 5/11, so 6 tiers were not actually tested. Phase 13 fixed the script crash, investigated the 3 failures, [regression fixes / pre-existing skips], and verified 11/11 tiers actually run and pass."
+
+---
+
+### 13.7 — MARK Phase 13 complete (state + metadata + tracks.md)
+
+- **WHERE:** `conductor/tracks/result_migration_small_files_20260617/state.toml` + `metadata.json` + `conductor/tracks.md`
+- **WHAT:**
+  - state.toml: mark all Phase 13 tasks completed with commit SHAs; update `status: active → completed`; `current_phase: 13 → "complete"`
+  - metadata.json: add Phase 13 outcomes (script_crash_fixed=true, regressions_fixed=N, pre_existing_failures_documented=N, test_pass_count=11/11)
+  - tracks.md: update the sub-track 2 row to reflect Phase 13 completion
+- **COMMIT:** `conductor(track): mark result_migration_small_files_20260617 Phase 13 complete (script crash fixed; 3 failures investigated; 11/11 tiers PASS)`
+- **GIT NOTE:** "Phase 13 is the ACTUAL completion. Phase 12 was rejected because the test claim was wrong. Phase 13 fixed the script crash, investigated the 3 failures, [regression fixes / pre-existing skips], and verified 11/11 tiers actually pass. The test count is 11, NOT 10. The 11th tier is tier-1-unit-comms."
+
+---
+
+### 13.8 — UPDATE the umbrella spec
+
+- **WHERE:** `conductor/tracks/result_migration_20260616/spec.md`
+- **WHAT:** Add a "Phase 13 Update" callout that:
+  - States Phase 12 was rejected for the false test claim
+  - Documents the script crash fix
+  - Documents the 3-failure investigation results
+  - States the final test pass count: 11/11 PASS
+- **COMMIT:** `docs(track): update umbrella with sub-track 2 Phase 13 complete (REAL completion; 11/11 verified)`
+- **GIT NOTE:** "Phase 13 is the actual completion. 11/11 tiers PASS, verified."
+
+---
+
+### 13.9 — Conductor - User Manual Verification
+
+The user manually verifies:
+- The script crash fix (13.1) is correct and the script now runs to completion
+- The 3-failure investigation (13.2) accurately identifies pre-existing vs regression
+- Any regression fixes (13.3) are correct
+- Any pre-existing skips (13.4) are documented honestly
+- The final test pass count (13.5) is 11/11 (or 10/11 + 1 documented skip)
+- The report (13.6) accurately reflects the actual test results

 ## Risks at the Plan Level
 
 | Risk | Mitigation |
@@ -482,19 +1423,39 @@ The narrowing in sub-track 2 created 14 new UNCLEAR sites that the audit doesn't
 | **Phase 10 R1:** A site that looks like a SILENT_SWALLOW fallback is actually a conditional capture that needs to inspect the exception to decide what to do | The full Result migration preserves the exception in `result.errors[0].exception`; the caller can inspect it. If the caller needs to branch on the exception, that's a follow-up for the caller (not this phase) |
 | **Phase 10 R2:** Migrating `Result[T]` through `io_pool` callbacks (warmup) requires the io_pool's API to accept `Result[T]` returns | The io_pool already uses callback-based dispatch; the Result is delivered to the completion handler as a parameter. No io_pool change needed; the caller is updated to check `result.ok` |
 | **Phase 10 R3:** The 2-3 new audit heuristics misclassify sites that should be `INTERNAL_BROAD_CATCH` or `INTERNAL_SILENT_SWALLOW` | TDD: each heuristic has a failing test first; the test suite covers the canonical patterns. If a heuristic is too broad, narrow the conditions and re-test |
+| **Phase 11 R1 (NEW):** Tier-2 may try to use the same LAUNDERING HEURISTICS approach again | The plan REQUIRES full Result migration for the 21 sites; the laundering heuristics are EXPLICITLY REVERTED. The test count claim must be 11 tiers, not 10. The per-site report must clearly state "Phase 10 REJECTED; Phase 11 is the actual completion." Any "narrow + log" pattern is REJECTED. |
+| **Phase 11 R2 (NEW):** Tier-2 may try to use "context manager" or "user callback" as excuses for not doing Result migration | `StartupProfiler.phase()` is NOT a context manager. The user callbacks in `WarmupManager` are `Callable[[dict], None]` and stay as-is; the MANAGER's INTERNAL methods are NOT user code. **Look at `src/hot_reloader.py`** for the pattern tier-2 used correctly. Apply the same pattern to `warmup.py`. |
+| **Phase 11 R3 (NEW):** Tier-2 may miscount the test tiers again (claiming 10 instead of 11) | The plan EXPLICITLY says "all 11 test tiers PASS" in Task 11.7.2. The 11th tier is `tier-1-unit-comms`. The report MUST say 11, not 10. |
+| **Phase 11 R4 (NEW):** Tier-2 may claim the work is done without doing the FULL Result migration for all 21 sites | Each of the 21 sites has a specific task (11.3.1.1 - 11.3.10.1). The plan EXPLICITLY lists each site. The "G4 met" claim requires the audit to show 0 migration-target sites WITHOUT the 5 LAUNDERING HEURISTICS in place. |
+| **Phase 12 R1 (NEW):** Tier-2 may keep the laundering-heuristic mindset and try to keep Heuristic #19 | Phase 12.1 EXPLICITLY REMOVES Heuristic #19. The user's principle: logging is NOT a drain. Result[T] propagates to drain points. The plan EXPLICITLY states this. |
+| **Phase 12 R2 (NEW):** Tier-2 may not fix the visit_Try audit bug, leaving nested Trys silently missed | Phase 12.2 EXPLICITLY FIXES the bug with a 2-line change. The fix is verified by re-running the audit on `src/api_hooks.py` and confirming the count is 23 (not 5). The TDD test (12.2.1) is non-bypassable. |
+| **Phase 12 R3 (NEW):** Tier-2 may not add Heuristic D (True Drain-Point Recognition) and end up flagging all HTTP error responses / GUI error displays as violations | Phase 12.3 EXPLICITLY ADDS Heuristic D with 5 patterns (HTTP error response, GUI error display, app termination, telemetry emission, retry-with-bounded-attempts). TDD-first; each pattern has a passing test. The small set of legitimate drain points is recognized. |
+| **Phase 12 R4 (NEW):** Tier-2 may claim Phase 12 is done but leave sites un-migrated | The per-file migration (12.6.1-12.6.13) lists every file:line. The triage (12.5) is the master list. Every site in the triage MUST be migrated or classified as a drain point (via Heuristic D). The audit's post-Phase-12 count must reflect the new state. |
+| **Phase 12 R5 (NEW):** Tier-2 may miscount test tiers (claiming 10 instead of 11) AGAIN | The plan EXPLICITLY says "ALL 11 TIERS PASS" in Task 12.9. The 11th tier is `tier-1-unit-comms`. This is the FOURTH time this is being emphasized. |
+| **Phase 12 R6 (NEW):** Tier-2 may claim "Phase 12 complete" without running the test suite | Task 12.9 is the test verification. The completion commit (12.11) requires all 11 test tiers passing. The user verifies via 12.13 (Conductor - User Manual Verification). |
+| **Phase 12 R7 (NEW):** The migration may break behavior in a way the test suite doesn't catch | Task 12.9 catches regressions. For non-tier-tested files, manual smoke-testing is added (sub-task of 12.6.x). |

+After Phase 12, capture in `docs/reports/RESULT_MIGRATION_SMALL_FILES_20260617.md` and `docs/reports/TRACK_COMPLETION_result_migration_small_files_20260617.md`:
 
+- **The user's principle (2026-06-17, in CAPS):** Result[T] propagates until it reaches a drain point. Logging is NOT a drain. The app should almost never crash unless something critical fails.
+- Phase 10 REJECTED: 21 sites slimed; 5 LAUNDERING HEURISTICS (#22-#26) added.
+- Phase 11 REJECTED: Heuristic #19 (narrow+log = compliant) was laundering; visit_Try audit bug not fixed; ~18+ nested-Try sites silently missed; tier-2 misclassified 2 sites.
+- Phase 12 (this phase): Heuristic #19 REMOVED; visit_Try FIXED; Heuristic D ADDED (5 drain-point patterns); N new sites Result-typed.
 - Audit pre-Phase-1: 76 sites (62V + 10S + 4?); 3 audit-script bugs documented
-- Audit post-Phase-1: 0 audit-script bugs (the 3 bugs are fixed)
-- Audit post-Phase-2: 4 UNCLEAR sites classified (decision count by category)
+- Audit post-Phase-1: 3 audit-script bugs fixed (visit_Try walker, render_json filter, render_json truncation)
+- Audit post-Phase-2: 4 UNCLEAR sites classified (2 compliant + 2 migration-target)
 - Audit post-Phase-9: 49/76 sites migrated; 27 SILENT_SWALLOW remain; 14 new UNCLEAR sites
-- Audit post-Phase-10: 76/76 sites migrated (49 from Phase 3-8 + 27 from Phase 10); 0 SILENT_SWALLOW; 0 UNCLEAR (the 14 reclassified via 2-3 new heuristics)
-- Per-file migration summary (76 sites → 0; per-file counts; per-site function signatures + ErrorInfo fields)
-- Per-site decisions for the 4 UNCLEAR sites
-- Audit-script bug-fix summary (3 from Phase 1 + 2-3 from Phase 10; per-bug description + fix)
-- Test pass count: all 11 tiers PASS; new tests added (4 for Phase 1 + N for Phase 10 heuristics + M for Phase 10 migrations)
+- Audit post-Phase-10 (REJECTED): 5 sites full Result + 21 sites narrowed+log; 5 LAUNDERING HEURISTICS (#22-#26) added
+- Audit post-Phase-11 (REJECTED): 5 LAUNDERING HEURISTICS REVERTED; 5 sites full Result + 2 helper extracts; 14 sites claimed as "already compliant" (6 legitimately, 2 misclassified, 6+ silently missed by visit_Try bug)
+- Audit post-Phase-12: 0 SILENT_SWALLOW; 0 UNCLEAR; 0 laundering heuristics; 0 migration-target; the small set of true drain points (HTTP responses, GUI error displays, app terminations, telemetry emissions, retry-with-bounded-attempts) is correctly recognized by Heuristic D
+- Per-file migration summary (76 + N new sites → 0 migration-target; per-file counts; per-site function signatures + ErrorInfo fields)
+- Per-site decisions for the 4 UNCLEAR sites (Phase 2)
+- Per-site drain-point decisions (Phase 12.6.x) — for each site, state whether it's a drain point (Heuristic D) or a Result-typed function
+- Audit-script changes: 3 from Phase 1 + visit_Try fix (Phase 12.2) + Heuristic #19 removal (Phase 12.1) + Heuristic D (Phase 12.3) + Heuristic A (Phase 11.2)
+- **Test pass count: ALL 11 TIERS PASS** (not 10; the 11th tier is `tier-1-unit-comms`; tier-2 had been miscounting in 3 prior phases); new tests added (4 for Phase 1 + 2 for Heuristic A + 5 for Heuristic D + N for the migrations)
+- The io_pool callback sites (`warmup.py:139/215/249`) thread the Result through the completion handler (same pattern as `src/hot_reloader.py`)
+- `startup_profiler.py:40` was MIGRATED via the `_log_phase_output` helper (phase() IS `@contextmanager`; the helper extraction is the partial-migration workaround; tier-2's original claim that phase() is "not a context manager" was wrong, and the plan's claim that "phase() is not a context manager" was also wrong — phase() IS `@contextmanager`; the helper extraction is the correct workaround)

+# Track Plan: Tier 2 Sandbox - Move State/Failures Off AppData
+
+**Goal:** move failcount state and failure-report locations inside the Tier 2 clone; remove all AppData references from Tier 2 conventions, permissions, scripts, docs, and tests.
+**Scope:** 11 source files + 3 test files + 1 doc + 1 workflow.md section + 1 .gitignore.
+**Convention:** 1-space Python indentation. CRLF where the file is already CRLF (do not normalize).
+
+## Phase 1: Move the default state and failure-report paths
+
+Focus: change the Python defaults so load/save use `scripts/tier2/state/...` and `scripts/tier2/failures/...` when no env-var override is set.
+
+### Task 1.1: Update `scripts/tier2/failcount.py:_state_dir` default
+- **WHERE:** `scripts/tier2/failcount.py:117-123` (the `_state_dir(track_name)` function).
+- **WHAT:** change the default `base` from `r"C:\Users\Ed\AppData\Local\manual_slop\tier2"` to `Path.cwd() / "scripts" / "tier2" / "state"` (computed when the function is called; `Path` import already present at line 11).
+- **HOW:** rewrite the function as:
+  ```python
+  def _state_dir(track_name: str) -> Path:
+      base_str = os.environ.get("TIER2_STATE_DIR")
+      if base_str:
+          return Path(base_str) / track_name
+      return Path.cwd() / "scripts" / "tier2" / "state" / track_name
+  ```
+- **SAFETY:** preserve the env-var escape hatch (`TIER2_STATE_DIR`); preserve the `Path` return type. The function has no other callers.
+- **COMMIT:** `fix(tier2): move failcount state default inside Tier 2 clone (scripts/tier2/state/)`
+
+### Task 1.2: Update `scripts/tier2/write_report.py:_failures_dir` default
+- **WHERE:** `scripts/tier2/write_report.py:20-23` (the `_failures_dir()` function).
+- **WHAT:** change the default from `r"C:\Users\Ed\AppData\Local\manual_slop\tier2_failures"` to `Path.cwd() / "scripts" / "tier2" / "failures"`.
+- **HOW:** rewrite the function as:
+  ```python
+  def _failures_dir() -> Path:
+      base_str = os.environ.get("TIER2_FAILURES_DIR")
+      if base_str:
+          return Path(base_str)
+      return Path.cwd() / "scripts" / "tier2" / "failures"
+  ```
+- **SAFETY:** preserve `TIER2_FAILURES_DIR` env-var override; preserve the `Path` return type. Callers are `compute_report_path`, `compute_stopped_flag_path`, and `write_failure_report` (all in the same file).
+- **COMMIT:** `fix(tier2): move failure-report default inside Tier 2 clone (scripts/tier2/failures/)`
+
+### Task 1.3: `scripts/tier2/run_track.py` chdir before state calls
+- **WHERE:** `scripts/tier2/run_track.py:run_init` (around line 78, before `save_state`) and `run_track.py:run_report` (around line 100, before `write_failure_report`).
+- **WHAT:** add `os.chdir(repo_path)` so `Path.cwd()` in `_state_dir` / `_failures_dir` resolves to the repo root.
+- **HOW:** add `import os` at the top (the file already imports `argparse`, `subprocess`, `sys`, `datetime`, `pathlib`); add `os.chdir(repo_path)` as the first line of `run_init` and `run_report`.
+- **SAFETY:** `os.chdir` is process-global; this is acceptable because `run_track.py` is the CLI entry point, not a library. The chdir is idempotent within a single invocation.
+- **COMMIT:** `fix(tier2): chdir to repo_path in run_track before state/report calls`
+
+### Task 1.4: Add `scripts/tier2/state/` and `scripts/tier2/failures/` to .gitignore
+- **WHERE:** `.gitignore` (top-level). Currently excludes `scripts/generated` on line 11.
+- **WHAT:** add `scripts/tier2/state/` and `scripts/tier2/failures/` after the `scripts/generated` line.
+- **HOW:** edit the file in place.
+- **SAFETY:** these are track-isolated scratch dirs; committing them would pollute the tree.
+- **COMMIT:** `chore(tier2): gitignore scripts/tier2/state/ and scripts/tier2/failures/`
+
+## Phase 2: Update OpenCode permissions and agent/command prompts
+
+Focus: remove AppData allow rules from the OpenCode JSON fragment; update the agent prompt and slash command to say "NEVER USE APPDATA".
+
+### Task 2.1: `conductor/tier2/opencode.json.fragment` — remove AppData allow rules
+- **WHERE:** lines 10-11, 16-17, 62-63, 68-69 (the `permission.read` and `permission.write` blocks at top level and at the `tier2-autonomous` agent level).
+- **WHAT:** delete the two `C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2\\**` and `C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2_failures\\**` allow rules. The remaining allow rule (the Tier 2 clone path) is unchanged.
+- **HOW:** four targeted `edit_file` calls (one per `read`/`write` block × top-level/agent).
+- **SAFETY:** keep the existing `*AppData\\Local\\Temp\\*` bash deny rule. **Do NOT** modify the bash rules in this task — that's Task 2.2.
+- **COMMIT:** `fix(tier2): remove AppData allow rules from OpenCode permission JSON`
+
+### Task 2.2: `conductor/tier2/opencode.json.fragment` — add `*AppData\\*` bash deny
+- **WHERE:** the `permission.bash` block at top level (line 46) and at the `tier2-autonomous` agent level (line 73).
+- **WHAT:** add `"*AppData\\*": "deny"` after the existing `"*AppData\\Local\\Temp\\*": "deny"` rule. The broader pattern catches `Local`, `LocalLow`, `Roaming`, and any other subdir.
+- **HOW:** two targeted edits.
+- **SAFETY:** the rule denies any bash command containing `AppData\`. Legitimate Tier 2 work does not write there. Combined with Task 2.1 (no allow rules), this is belt-and-suspenders.
+- **COMMIT:** `fix(tier2): add *AppData\\* bash deny rule (broader than just Temp)`
+
+### Task 2.3: `conductor/tier2/agents/tier2-autonomous.md` — replace AppData convention
+- **WHERE:** line 47 (the "Temp files" bullet under "Conventions (MUST follow - added 2026-06-17)").
+- **WHAT:** replace the entire bullet. The new bullet says: "All scratch, state, audit-output, and intermediate files MUST live inside the Tier 2 clone (the OpenCode `*` deny rule blocks everything else). Default locations: `scripts/tier2/state/<track>/state.json` for failcount state, `scripts/tier2/failures/` for failure reports, `scripts/tier2/artifacts/<track>/` for throwaway scripts. **The `C:\Users\Ed\AppData\...` tree is OFF-LIMITS** for any read, write, or shell command. The OpenCode `*AppData\\*` bash deny rule enforces this."
+- **HOW:** edit_file on the bullet's full text.
+- **SAFETY:** preserve the env-var escape-hatch language (TIER2_STATE_DIR / TIER2_FAILURES_DIR are honored if set).
+- **COMMIT:** `docs(tier2): agent prompt - replace AppData convention with inside-clone convention`
+
+### Task 2.4: `conductor/tier2/commands/tier-2-auto-execute.md` — replace AppData convention
+- **WHERE:** line 46 (the "Temp files" bullet under "Conventions (MUST follow - added 2026-06-17)").
+- **WHAT:** identical change to Task 2.3, applied to the slash command prompt. Also update line 19 ("Check for a previous run" — the path is `<app-data>/tier2/<track-name>/state.json`) and line 25 (step 3 in Protocol — "Initialize failcount state at `<app-data>/tier2/<track-name>/state.json`") to reference `scripts/tier2/state/<track-name>/state.json`.
+- **HOW:** three edit_file calls.
+- **SAFETY:** the slash command prompt is what the Tier 2 agent reads; if it still says `<app-data>`, the agent will continue trying to use AppData.
+- **COMMIT:** `docs(tier2): slash command - replace AppData paths with inside-clone paths`
+
+## Phase 3: Update bootstrap scripts
+
+Focus: `setup_tier2_clone.ps1` and `run_tier2_sandboxed.ps1` stop creating/referencing AppData dirs.
+
+### Task 3.1: `scripts/tier2/setup_tier2_clone.ps1` — remove AppData dir creation
+- **WHERE:** lines 23 (`$AppDataDir`), 30 (`$AppDataFailuresDir`), 122-133 (the `New-Item` / `Get-Acl` / `Set-Acl` block).
+- **WHAT:** delete the `$AppDataDir` and `$AppDataFailuresDir` parameter / variable declarations and the entire "Create app-data dir with restricted ACLs" step block. Update the docstring (lines 6-9) to remove the "creates the app-data temp dir with restricted ACLs" sentence.
+- **HOW:** three edit_file calls.
+- **SAFETY:** the script must still create the Tier 2 clone, copy templates, install git hooks, and create the desktop shortcut. The deleted step is purely about AppData dirs.
+- **COMMIT:** `fix(tier2): setup_tier2_clone.ps1 - stop creating AppData dirs`
+
+### Task 3.2: `scripts/tier2/run_tier2_sandboxed.ps1` — remove AppData dir references
+- **WHERE:** lines 20-21 (`$AppDataDir`, `$AppDataFailuresDir`), line 7 (docstring), line 77 (the "Set explicit ACLs on the Tier 2 clone + app-data dir" comment).
+- **WHAT:** delete the `$AppDataDir` / `$AppDataFailuresDir` variable declarations and any ACL-set logic that references them. Update the docstring (line 7) to remove "app-data dir" from the list.
+- **HOW:** four edit_file calls.
+- **SAFETY:** the restricted-token + Job-Object + launch logic must stay intact.
+- **COMMIT:** `fix(tier2): run_tier2_sandboxed.ps1 - remove AppData dir references`
+
+## Phase 4: Update tests
+
+Focus: flip the slash-command-spec tests so they assert "no AppData refs" instead of "AppData refs required"; update `test_no_temp_writes.py` docstring and fix-message.
+
+### Task 4.1: `tests/test_tier2_slash_command_spec.py:test_agent_denies_temp_writes`
+- **WHERE:** lines 82-91 (the entire `test_agent_denies_temp_writes` function).
+- **WHAT:** flip the assertions. Replace:
+  ```python
+  assert 'AppData\\Local\\Temp' in content, "agent prompt must include Temp deny rule in frontmatter bash"
+  assert 'AppData\\Local\\manual_slop\\tier2' in content or 'app-data' in content.lower(), "agent prompt must point agent at the app-data dir for temp files"
+  ```
+  with:
+  ```python
+  assert 'AppData\\Local\\Temp' in content, "agent prompt must include Temp deny rule in frontmatter bash"
+  assert "*AppData\\\\*" in content or "AppData\\\\*" in content, "agent prompt must include the broader AppData deny rule"
+  assert "scripts/tier2/state" in content, "agent prompt must point agent at scripts/tier2/state for failcount state"
+  assert "scripts/tier2/failures" in content, "agent prompt must point agent at scripts/tier2/failures for failure reports"
+  assert "AppData\\Local\\manual_slop\\tier2" not in content, "agent prompt must NOT reference the AppData tier2 dir (2026-06-18 hard ban)"
+  ```
+  Update the docstring to mention the 2026-06-18 reversal.
+- **HOW:** edit_file on the function body and docstring.
+- **SAFETY:** the `*AppData\\*` substring check matches the literal JSON bash key `"*AppData\\*"`. Be careful with Python string-escape semantics — use a raw string or a literal substring that survives the JSON double-escape.
+- **COMMIT:** `test(tier2): slash_command_spec - assert no AppData refs, point at inside-clone`
+
+### Task 4.2: `tests/test_tier2_slash_command_spec.py:test_command_denies_temp_writes` (or the equivalent for the command file)
+- **WHERE:** the parallel test for the slash command prompt (likely also in `tests/test_tier2_slash_command_spec.py`).
+- **WHAT:** apply the same flip as Task 4.1 to the command prompt content.
+- **HOW:** edit_file.
+- **SAFETY:** keep the Temp deny assertion; add the new inside-clone-pointing assertions; remove the AppData-required assertion.
+- **COMMIT:** `test(tier2): slash_command_spec - command prompt assert no AppData refs`
+
+### Task 4.3: `tests/test_no_temp_writes.py` docstring + fix message
+- **WHERE:** lines 1-15 (the docstring) and line 33 (the fix-message string).
+- **WHAT:** replace the AppData paths in the docstring (lines 6-7) with `scripts/tier2/state/` and `scripts/tier2/failures/`. Replace the fix-message suggestion on line 33 (`C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2\\ instead of %TEMP%.`) with `scripts/tier2/state/ or scripts/tier2/failures/ instead of %TEMP%.`.
+- **HOW:** edit_file.
+- **SAFETY:** the audit script's behavior is unchanged; only the human-facing strings change.
+- **COMMIT:** `test(tier2): no_temp_writes - replace AppData refs in docstring + fix message`
+
+## Phase 5: Update user-facing docs and workflow
+
+Focus: `docs/guide_tier2_autonomous.md` and `conductor/workflow.md` stop referencing AppData.
+
+### Task 5.1: `docs/guide_tier2_autonomous.md` — replace AppData refs
+- **WHERE:** line 24 (bootstrap step 5), line 59 (the "4 hard bans" table row), line 72 (failure report location), lines 119-129 (Troubleshooting section).
+- **WHAT:** replace each `C:\Users\Ed\AppData\Local\manual_slop\tier2...` reference with the new `scripts/tier2/state/...` / `scripts/tier2/failures/...` paths.
+- **HOW:** multiple edit_file calls (one per paragraph that contains an AppData path).
+- **SAFETY:** the guide's structure and other content stay intact; only path strings change.
+- **COMMIT:** `docs(tier2): guide_tier2_autonomous - replace AppData paths with inside-clone paths`
+
+### Task 5.2: `conductor/workflow.md` — update hard bans table
+- **WHERE:** line 386 (the row "File access outside Tier 2 clone + app-data dir").
+- **WHAT:** replace with "File access outside Tier 2 clone (AppData, Temp, Documents, etc. all denied at the OpenCode `*` level + targeted `*AppData\\*` deny)."
+- **HOW:** edit_file.
+- **SAFETY:** the surrounding 3-layer-enforcement table structure stays.
+- **COMMIT:** `docs(tier2): workflow.md hard bans - AppData denied (no exception)`
+
+### Task 5.3: `scripts/tier2/write_track_completion_report.py` — update report output
+- **WHERE:** lines 262, 264 (the "Filesystem boundary" and "Failcount monitored" rows in the generated report).
+- **WHAT:** replace the AppData path strings with `scripts/tier2/state/...` / `scripts/tier2/failures/...`.
+- **HOW:** two edit_file calls.
+- **SAFETY:** the generated report's structure stays; only path strings change. The report's downstream consumers (the user reading it after a Tier 2 run) need to see the actual paths the next run will use.
+- **COMMIT:** `fix(tier2): write_track_completion_report - use inside-clone paths in output`
+
+## Phase 6: Conductor verification
+
+Focus: ensure the test suite still passes after the changes; register the track in `conductor/tracks.md`.
+
+### Task 6.1: Run targeted test batches
+- **COMMAND:** `uv run python scripts/run_tests_batched.py --tier tier-1-unit-core tests/test_failcount.py tests/test_tier2_report_writer.py tests/test_tier2_slash_command_spec.py tests/test_no_temp_writes.py`
+- **EXPECTED:** all 4 test files pass. The `test_failcount` and `test_tier2_report_writer` env-var tests pass because they monkeypatch the env var (FR7's backward-compat requirement). The `test_tier2_slash_command_spec` tests pass because the new assertions match the updated agent prompt and slash command. The `test_no_temp_writes` test passes because the audit script's behavior didn't change.
+- **COMMIT:** no commit (this is a verification step).
+
+### Task 6.2: Run the static analyzer batch
+- **COMMAND:** `uv run python scripts/audit_no_temp_writes.py --strict`
+- **EXPECTED:** `CLEAN: no script under ./scripts/ emits to %TEMP%` and exit code 0. The audit's exclusion list (`scripts/tier2/artifacts`) covers the throwaway scripts that may still have AppData path strings.
+- **COMMIT:** no commit.
+
+### Task 6.3: Register the track in `conductor/tracks.md`
+- **WHERE:** append a new entry block following the precedent set by `tier2_autonomous_sandbox_20260616`.
+- **WHAT:** add the link, spec, plan, metadata, status, and a one-line summary.
+- **COMMIT:** `conductor(tracks): register tier2_no_appdata_20260618 (shipped)` (after Phase 1-5 commit SHAs are recorded).
+
+---
+
+## End-of-Track Report (added 2026-06-17 convention)
+
+On Phase 6 completion, write `docs/reports/TRACK_COMPLETION_tier2_no_appdata_20260618.md` following the precedent set by `docs/reports/TRACK_COMPLETION_tier2_autonomous_sandbox_20260616.md`. Update `conductor/tracks/tier2_no_appdata_20260618/state.toml` to `status = "completed"`.

+# Track Specification: Tier 2 Sandbox - Move State/Failures Off AppData
+
+**Track ID:** `tier2_no_appdata_20260618`
+**Date:** 2026-06-18
+**Priority:** A (the in-flight Tier 2 run for `live_gui_test_fixes_20260618` is blocked by the AppData path assumption; a future Tier 2 clone will inherit the broken config unless this ships)
+**Type:** fix (convention + infrastructure; no behavior change in product code)
+
+## Overview
+
+The Tier 2 autonomous sandbox currently persists its failcount state to `C:\Users\Ed\AppData\Local\manual_slop\tier2\<track>\state.json` and writes failure reports to `C:\Users\Ed\AppData\Local\manual_slop\tier2_failures\`. The OpenCode permission JSON allowlists both. The user has explicitly directed: **"NEVER USE APPDATA"** — meaning the whole `C:\Users\Ed\AppData\...` tree should be off-limits to the Tier 2 sandbox.
+
+This track moves both the state and the failure-report directories **inside the Tier 2 clone** (`C:\projects\manual_slop_tier2\`) and removes every AppData reference from the conventions, the agent prompt, the slash command, the OpenCode JSON fragment, the bootstrap scripts, the user guide, and the tests. After this track, `C:\Users\Ed\AppData\...` is never referenced by the Tier 2 sandbox in any form.
+
+## Current State Audit (as of 2026-06-18, commit 02aed999)
+
+### Already Implemented (DO NOT re-implement)
+
+- **Tier 2 sandbox enforcement (3-layer):** OpenCode `permission.bash` deny rules + Windows restricted token + git hooks. Shipped in `tier2_autonomous_sandbox_20260616` (commit `00c6922c`).
+- **`*AppData\Local\Temp\*` deny rule:** already blocks the global Temp dir (the 2026-06-17 regression fix). The bash deny keys are present in both the top-level and the `tier2-autonomous` agent's `permission.bash`.
+- **`scripts/audit_no_temp_writes.py`:** scans `./scripts/**` for any `%TEMP%` / `tempfile.` / `$env:TEMP` usage. Default-on regression test `tests/test_no_temp_writes.py` invokes it with `--strict`.
+- **TIER2_STATE_DIR / TIER2_FAILURES_DIR env-var overrides:** `scripts/tier2/failcount.py` and `scripts/tier2/write_report.py` already accept env-var overrides; the AppData paths are just the *defaults*.
+
+### Gaps to Fill (This Track's Scope)
+
+The AppData paths are still the **defaults** for failcount state and failure reports, and the conventions/permissions/tests all reinforce them:
+
+1. **`scripts/tier2/failcount.py:117-123`** — `_state_dir(track_name)` defaults to `r"C:\Users\Ed\AppData\Local\manual_slop\tier2"` when `TIER2_STATE_DIR` is unset.
+2. **`scripts/tier2/write_report.py:20-23`** — `_failures_dir()` defaults to `r"C:\Users\Ed\AppData\Local\manual_slop\tier2_failures"` when `TIER2_FAILURES_DIR` is unset.
+3. **`conductor/tier2/opencode.json.fragment`** — `permission.read` and `permission.write` allowlist `C:\Users\Ed\AppData\Local\manual_slop\tier2\**` and `C:\Users\Ed\AppData\Local\manual_slop\tier2_failures\**` at both the top level and the `tier2-autonomous` agent level. These allow rules *keep the door open* — even if the agent is told not to use AppData, the permission system *would* allow it.
+4. **`conductor/tier2/agents/tier2-autonomous.md`** — explicitly tells the agent "Use `C:\Users\Ed\AppData\Local\manual_slop\tier2\` for all scratch / audit-output / temp files." (Line 47)
+5. **`conductor/tier2/commands/tier-2-auto-execute.md`** — same instruction at line 46.
+6. **`scripts/tier2/setup_tier2_clone.ps1:122-133`** — creates `C:\Users\Ed\AppData\Local\manual_slop\tier2\` and `C:\Users\Ed\AppData\Local\manual_slop\tier2_failures\` with restricted ACLs on bootstrap.
+7. **`scripts/tier2/run_tier2_sandboxed.ps1:20-21,77`** — references the AppData dirs and sets ACLs on them.
+8. **`docs/guide_tier2_autonomous.md`** — 4 explicit AppData references (lines 24, 72, 119, 128).
+9. **`conductor/workflow.md:386`** — hard bans table says "File access outside Tier 2 clone + app-data dir."
+10. **`scripts/tier2/write_track_completion_report.py:262,264`** — writes the AppData paths into the generated completion report.
+11. **`tests/test_tier2_slash_command_spec.py:91`** — asserts `'AppData\\Local\\manual_slop\\tier2' in content` (the test *requires* the agent prompt to reference AppData; this is the regression we are now reversing).
+12. **`tests/test_no_temp_writes.py:33`** — the failure-message string still suggests `C:\Users\Ed\AppData\Local\manual_slop\tier2\` as the fix target.
+
+### Root Cause
+
+The `tier2_autonomous_sandbox_20260616` track (shipped 2026-06-16) chose AppData because (a) it's outside the project tree so it doesn't pollute git, and (b) Windows restricted tokens can have explicit ACLs applied to AppData subdirs while keeping the rest of the user profile accessible. The trade-off was never questioned because Tier 2 was working.
+
+On 2026-06-17, the agent attempted to write an audit JSON to `C:\Users\Ed\AppData\Local\Temp\` (the wrong AppData path — the system Temp, not the manual_slop one). The OpenCode permission system denied it because `*AppData\Local\Temp\*` was in the bash deny list, but the agent was confused because the *prompt* said "use AppData" and the *allowlist* said "AppData/Local/manual_slop/tier2/ is OK." The 2026-06-17 fix added the Temp deny rule and the AppData instruction to the prompt — but the underlying assumption (AppData is fine) was still baked in.
+
+On 2026-06-18, the user issued the directive: **"NEVER USE APPDATA."** This is a stronger rule than the 2026-06-17 fix. The Tier 2 sandbox must stop treating AppData as a scratch space, period.
+
+## Goals
+
+1. **Zero AppData references in Tier 2 conventions.** The agent prompt, slash command, user guide, and OpenCode JSON must never say "use C:\Users\Ed\AppData\..." for any purpose.
+2. **Default state location = inside the clone.** `scripts/tier2/state/<track>/state.json` (relative to the clone root, computed via `Path.cwd()` when the agent runs).
+3. **Default failure-report location = inside the clone.** `scripts/tier2/failures/<track>_<utc-ts>.md` and `scripts/tier2/failures/<track>.STOPPED`.
+4. **Permission system refuses AppData.** OpenCode JSON `read`/`write` must not allowlist any `C:\Users\Ed\AppData\...` path. The deny rule for `*AppData\Local\Temp\*` stays; we add `*AppData\*` deny rules as a belt-and-suspenders.
+5. **Bootstrap does not create AppData dirs.** `setup_tier2_clone.ps1` and `run_tier2_sandboxed.ps1` no longer reference AppData.
+6. **Tests assert the new behavior.** `tests/test_tier2_slash_command_spec.py` and `tests/test_no_temp_writes.py` are updated to assert no AppData references in the agent prompt / fix messages.
+7. **Backward-compatible env-var escape hatch.** The existing `TIER2_STATE_DIR` / `TIER2_FAILURES_DIR` env-var overrides are preserved (still honored if set), but the *default* moves inside the clone.
+
+## Functional Requirements
+
+**FR1. State location moves inside the clone.**
+- `scripts/tier2/failcount.py:_state_dir` returns `Path.cwd() / "scripts" / "tier2" / "state" / track_name` by default.
+- `TIER2_STATE_DIR` env-var override is preserved.
+- `run_track.py:run_init` does `os.chdir(repo_path)` before calling `save_state` so `Path.cwd()` resolves to the clone root.
+
+**FR2. Failure-report location moves inside the clone.**
+- `scripts/tier2/write_report.py:_failures_dir` returns `Path.cwd() / "scripts" / "tier2" / "failures"` by default.
+- `TIER2_FAILURES_DIR` env-var override is preserved.
+- `run_track.py:run_report` does `os.chdir(repo_path)` before calling `write_failure_report`.
+
+**FR3. OpenCode permission JSON removes AppData allow rules.**
+- `conductor/tier2/opencode.json.fragment`: top-level and `tier2-autonomous` agent — `read`/`write` allow rules for `C:\Users\Ed\AppData\Local\manual_slop\tier2\**` and `C:\Users\Ed\AppData\Local\manual_slop\tier2_failures\**` are removed.
+- The existing `*AppData\Local\Temp\*` bash deny rule stays.
+- A new `*AppData\*` bash deny rule is added (belt-and-suspenders — the OpenCode `*` deny already blocks AppData reads, but a shell command like `> C:\Users\Ed\AppData\Local\foo.txt` was previously allowed because the bash `*` was set to `allow` at the agent level; tightening to `*` deny is too restrictive, so the targeted deny on `*AppData\*` is the surgical fix).
+
+**FR4. Agent prompt and slash command say "NEVER USE APPDATA".**
+- `conductor/tier2/agents/tier2-autonomous.md` "Temp files" convention replaced with: "All scratch, state, and audit-output files MUST live inside the Tier 2 clone (`scripts/tier2/state/`, `scripts/tier2/failures/`, `scripts/tier2/artifacts/<track>/`). The `C:\Users\Ed\AppData\...` tree is OFF-LIMITS for any read, write, or shell command. This is enforced by the OpenCode `*AppData\*` deny rule; a violation will halt the run."
+- `conductor/tier2/commands/tier-2-auto-execute.md` "Conventions" section: same update.
+
+**FR5. Bootstrap scripts stop creating AppData dirs.**
+- `scripts/tier2/setup_tier2_clone.ps1`: remove `$AppDataDir` / `$AppDataFailuresDir` variables and the `New-Item` / `Set-Acl` calls.
+- `scripts/tier2/run_tier2_sandboxed.ps1`: same.
+
+**FR6. Tests updated.**
+- `tests/test_tier2_slash_command_spec.py:test_agent_denies_temp_writes` — flipped assertion: the agent prompt must NOT contain `AppData\Local\manual_slop\tier2` and MUST contain `scripts/tier2/state` or `scripts/tier2/failures`.
+- `tests/test_tier2_slash_command_spec.py:test_command_denies_temp_writes` — same flip (the slash command prompt has the same convention).
+- `tests/test_no_temp_writes.py` docstring + fix message: replace the AppData suggestion with `scripts/tier2/state/` / `scripts/tier2/failures/`.
+
+**FR7. User guide updated.**
+- `docs/guide_tier2_autonomous.md`: 4 AppData references replaced with the new inside-clone locations. The "Verify the sandbox" checklist's `<app-data>` reference is removed.
+
+**FR8. Hard bans table updated.**
+- `conductor/workflow.md:386`: "File access outside Tier 2 clone + app-data dir" → "File access outside Tier 2 clone (AppData, Temp, Documents, etc. all denied)."
+
+**FR9. Completion report writer updated.**
+- `scripts/tier2/write_track_completion_report.py`: replace the 2 AppData path strings with the new `scripts/tier2/state/...` / `scripts/tier2/failures/...` paths.
+
+**FR10. .gitignore updated.**
+- `scripts/tier2/state/` and `scripts/tier2/failures/` added (track-isolated scratch, must not be committed).
+
+## Non-Functional Requirements
+
+- **No regressions:** all existing failcount and report-writer tests pass after the path changes. The existing `TIER2_STATE_DIR` / `TIER2_FAILURES_DIR` env-var tests (`tests/test_failcount.py:176,190,198` and `tests/test_tier2_report_writer.py:25,33,40,71`) continue to pass — they monkeypatch the env var, which overrides the default.
+- **CLI ergonomics:** `scripts/tier2/run_track.py` continues to take `--repo-path` (default `.`). The `os.chdir(repo_path)` call is silent and idempotent.
+- **The in-flight Tier 2 run is NOT broken by this change** — the Tier 2 clone at `C:\projects\manual_slop_tier2\` still has the old config until re-bootstrapped. The user's existing run for `live_gui_test_fixes_20260618` continues to use AppData as it was bootstrapped.
+
+## Architecture Reference
+
+- **`docs/guide_tier2_autonomous.md`** — the user-facing Tier 2 sandbox guide. Sections 1 (bootstrap), 5 (the 4 hard bans), 7 (the failure report), and Troubleshooting are all touched.
+- **`conductor/workflow.md` §"Tier 2 Autonomous Sandbox" (lines 365-396)** — the convention-level rules and the 3-layer enforcement table. The "Hard bans" row is updated.
+- **`conductor/code_styleguides/workspace_paths.md`** — the principle "test workspaces live in the project tree under `tests/artifacts/`" extends naturally to "Tier 2 scratch lives in the project tree under `scripts/tier2/state/` and `scripts/tier2/failures/`." We cite this principle in the spec; we don't modify the styleguide (it's about *test* workspaces, not Tier 2 scratch).
+
+## Out of Scope
+
+- Re-bootstrap of the live Tier 2 clone (`C:\projects\manual_slop_tier2\`). The user re-runs `pwsh -File scripts/tier2/setup_tier2_clone.ps1` after this track merges.
+- Migration of existing state from `C:\Users\Ed\AppData\Local\manual_slop\tier2\...` into `scripts/tier2/state/...`. Any in-flight run's state is discarded on the next re-bootstrap.
+- Repo-wide LF normalization (a separate future track).
+- Tier 2 audit script (`scripts/audit_no_temp_writes.py`) changes — it already correctly scans for `%TEMP%` patterns; the AppData path strings in its docstring are updated as part of FR6 (the test fix-message change).
