[AZ-511] classColors carve-out to src/class-colors/ (closes F3)

Move src/features/annotations/classColors.ts to its own component directory
src/class-colors/ with a proper barrel; update the 4 consumer imports to go
through the barrel; remove the F3-pending exemption from STC-ARCH-01 and from
the architecture test fixture; clean up the 5 coupled doc/script touchpoints.
Closes baseline finding F3 and retires the 5-coupled-places carry-over surface
logged in LESSONS.md 2026-05-12.

- Add `class-colors` to scripts/check-arch-imports.mjs COMPONENT_DIRS so deep
  imports past the new barrel are caught symmetric to every other component.
- Replace the architecture test "exemption WORKS" fixture with the stronger
  "deep import into class-colors NOW FAILS" assertion (Risk 4 mitigation).
- module-layout.md: Layout Rules + Per-Component Mapping (11_class-colors,
  06_annotations, 03_shared-ui) + Verification Needed #1 + shared/class-colors
  block all updated to reflect the new home.
- 11_class-colors/description.md: Caveats §7 + Module Inventory updated.
- architecture_compliance_baseline.md: F3 marked CLOSED with full pre-resolution
  context preserved (mirrors AZ-485/F4 + AZ-486/F7 pattern); F4 carry-forward
  exemption note retired.
- 04_verification_log.md: open questions #1 + #8 marked RESOLVED.
- Build passes with no circular-import warnings (AC-4); fast suite 231/13
  skipped green (AC-5); static profile green (AC-3 — zero exemptions remain).

 ### F4: No Public API barrels — every internal file is de-facto public (High / Architecture) — **CLOSED 2026-05-11 by AZ-485 (commit `23746ec`)**
 
 - **Resolution**: 11 component barrels (`src/<component>/index.ts`) added — one per component except `10_app-shell` (top-level file collection, never imported as a unit). Every cross-component import in `src/`, `tests/`, and `e2e/` now goes through the barrel. The `STC-ARCH-01` static gate (`scripts/check-arch-imports.mjs --mode=arch-imports`, wired into `scripts/run-tests.sh --static`) fails the build on any deep-import regression. The architecture test `tests/architecture_imports.test.ts` exercises the gate with synthetic fixtures (AC-4 fail-on-synthetic, AC-5 pass-on-migrated). Module-layout Layout Rule #3 records the convention.
-- **Carried-forward exemption**: `src/features/annotations/classColors` — the file is logically owned by `11_class-colors` but physically lives under `06_annotations` (F3). Re-exporting it through the `06_annotations` barrel creates a circular import (`AnnotationsPage → DetectionClasses → 06_annotations barrel → AnnotationsPage`). Consumers import the path directly under an `EXEMPT_RE` in the static check. The exemption disappears when F3 moves the file.
+- **Carried-forward exemption**: ~~`src/features/annotations/classColors`~~ — **CLOSED by AZ-511 (cycle 3 batch 14)**. The file moved to `src/class-colors/` with its own barrel; the `EXEMPT_RE` was removed from `scripts/check-arch-imports.mjs`. STC-ARCH-01 has zero exemptions today.

 - **Fallback names are generic English** ("Car", "Person", "Truck", …) and bear no relation to the actual military class taxonomy in `_docs/ui_design/README.md` §"Detection Classes Table". Acceptable only because they appear strictly when admin-loaded classes failed to load. Document in Step 5 (Solution Extraction).
 - **No localization**. Suffix strings (`' (winter)'`, `' (night)'`) and fallback names are hardcoded English. Step 4 i18n.
 - **Color palette size (12)** vs `base = 0..19` — the wrap-around silently reuses colors for indices 12..19. Visually distinct fallbacks above 12 are not guaranteed.

 ## Layout Rules
 
 1. Each component owns ONE OR MORE top-level directories (or top-level files) under `src/`. The mapping is NOT 1:1 — `00_foundation` owns three sibling directories (`src/types/`, `src/hooks/`, `src/i18n/`), `05_flights` spans `src/features/flights/` AND a separate `mission-planner/` port-source root, and `10_app-shell` owns top-level files (`App.tsx`, `main.tsx`, `index.css`, `vite-env.d.ts`).
-2. Shared code does **not** live under `src/shared/` today — there is no `shared/` directory. Two helper modules (`11_class-colors/classColors.ts` and `06_annotations/CanvasEditor.tsx`) are physically misplaced and consumed across components; both are flagged in the `## Verification Needed` block. A `src/shared/` directory is a Step 4 testability candidate.
-3. **Public API per component is the barrel `src/<component>/index.ts`** (AZ-485 / F4). Every component except `10_app-shell` (which is a top-level file collection — `App.tsx`, `main.tsx`, etc., never imported as a unit) exposes its Public API through a root barrel. Cross-component imports MUST go through the barrel — `import { api } from '../api'`, not `from '../api/client'`. The `STC-ARCH-01` static gate (`scripts/check-arch-imports.mjs`, wired into `scripts/run-tests.sh --static-only`) fails the build on cross-component deep imports. Intra-component imports (relative `./`) remain free. **One F3-pending exemption**: `src/features/annotations/classColors` is imported directly because the file is logically owned by `11_class-colors` but physically lives under `06_annotations`; re-exporting it through the `06_annotations` barrel creates a circular import (AnnotationsPage → DetectionClasses → 06_annotations barrel → AnnotationsPage). The exemption disappears when F3 moves the file.
+2. Shared code does **not** live under `src/shared/` today — there is no `shared/` directory. One helper module (`06_annotations/CanvasEditor.tsx`) remains physically misplaced and consumed across components; it is flagged in the `## Verification Needed` block. (`11_class-colors` was lifted to its own component directory `src/class-colors/` by AZ-511 / F3.) A `src/shared/` directory is a Step 4 testability candidate.
+3. **Public API per component is the barrel `src/<component>/index.ts`** (AZ-485 / F4). Every component except `10_app-shell` (which is a top-level file collection — `App.tsx`, `main.tsx`, etc., never imported as a unit) exposes its Public API through a root barrel. Cross-component imports MUST go through the barrel — `import { api } from '../api'`, not `from '../api/client'`. The `STC-ARCH-01` static gate (`scripts/check-arch-imports.mjs`, wired into `scripts/run-tests.sh --static-only`) fails the build on cross-component deep imports. Intra-component imports (relative `./`) remain free. **No exemptions today** (the prior F3 carry-over for `features/annotations/classColors` was removed by AZ-511 when the file moved to its own component).
 4. Cross-cutting concerns (logging, config, error handling, telemetry): no dedicated infrastructure today. `console.error` / silent catches are the closest thing — recorded in module findings.
 5. Tests: there are **zero tests** under `src/`. The only test file is `mission-planner/src/test/jsonImport.test.ts`, which can't run because Jest isn't installed (00_discovery.md §11.5). Test layout is therefore TBD; suggest `src/<component>/__tests__/` per the standard React convention when tests are added (autodev Step 5–6).

The single source of truth is `src/api/endpoints.ts` (re-exported via the `01_api-transport` barrel from rule #3). Every production callsite of `api.*` and `createSSE()` uses an `endpoints.*` builder; the colocated `src/api/endpoints.test.ts` pins every URL string and serves as the wire-contract documentation. The `STC-ARCH-02` static gate (`scripts/check-arch-imports.mjs --mode=api-literals`, wired into `scripts/run-tests.sh --static-only`) fails the build on any new hardcoded `/api/<service>/` literal under `src/`. Exemptions: `src/api/endpoints.ts` (the contract owner) and any `*.test.ts` / `*.test.tsx` under `src/` (test files are exempt because tests legitimately assert URL strings — MSW handlers, contract tests, etc.).

+- `_docs/02_document/module-layout.md` — Layout Rule #2 (one misplaced module remains: CanvasEditor; class-colors no longer counted), Layout Rule #3 (no exemptions today), Per-Component Mapping for `11_class-colors` (now owns `src/class-colors/**`), `06_annotations` (Owns no longer carves out classColors; Imports from now goes via barrel), `03_shared-ui` (Imports from notes the barrel), `## Shared / Cross-Cutting → shared/class-colors` (marked RESOLVED with back-pointer), Verification Needed #1 (RESOLVED), Verification Needed #3 (no exemption left).
+- `_docs/02_document/components/11_class-colors/description.md` — Caveats §7 rewritten ("Physical location: `src/class-colors/`"), Module Inventory updated to list both files at the new home.
+- `_docs/02_document/architecture_compliance_baseline.md` — F3 marked CLOSED 2026-05-13 by AZ-511 with full pre-resolution context preserved (mirrors AZ-485 → F4 / AZ-486 → F7 pattern); F4's "Carried-forward exemption" note retired.
+- `_docs/02_document/04_verification_log.md` — open questions #1 and #8 marked RESOLVED (adjacent hygiene; the questions were the open-question form of F3 and verification needed #1).
+
+### Resolved Finding
+
+- **F3** (`_docs/02_document/architecture_compliance_baseline.md`): Physical / logical owner split for `classColors.ts` — closed by AZ-511. The 5-coupled-places carry-over surface logged in `_docs/LESSONS.md` 2026-05-12 is fully retired.
+
+### Test Run
+
+- Static profile: PASS (STC-ARCH-01 with no exemptions, STC-ARCH-02 unchanged, all other gates green)
+- Fast profile: 31 files / 231 passed / 13 skipped (no test count change vs. AZ-510 baseline — quarantines unchanged)
+- Build: `bun run build` succeeded in 3.83s; 198 modules transformed; no circular-import warnings involving class-colors / annotations / DetectionClasses
+
+## Next Batch
+
+**Batch 15 (cycle 3 / batch 3 of 3)** — AZ-512 admin edit detection class. Spec carries a BLOCKING cross-workspace verification at impl time: `admin/` must expose `PATCH /api/admin/classes/{id}`. Will pause at that gate.

+# Code Review Report — Batch 14
+
+**Batch**: AZ-511 (classColors carve-out to `src/class-colors/`)
+**Cycle**: 3
+**Date**: 2026-05-13
+**Verdict**: PASS
+
+---
+
+## Phase 1: Context Loading
+
+- Task spec: `_docs/02_tasks/todo/AZ-511_classcolors_carve_out.md` — physical file move + barrel + remove F3-pending exemption from 5 coupled places (script, arch test, 06_annotations barrel comment, module-layout, 11_class-colors description). Closes baseline finding F3.
+- Architecture compliance baseline F3 (open) and the 2026-05-12 LESSONS.md entry "5 coupled places" gave the touchpoint inventory.
+- Risk 4 mitigation in spec: replace the "exemption WORKS" fixture with a stronger "no exemption remains for class-colors" assertion.
+
+## Phase 2: Spec Compliance
+
+| AC | Mechanism | Evidence |
+|----|-----------|----------|
+| AC-1 — file at new location | `git mv src/features/annotations/classColors.ts src/class-colors/classColors.ts`; barrel at `src/class-colors/index.ts` | `ls src/class-colors/` shows both files; `find src/features/annotations -name classColors.ts` returns nothing |
+| AC-2 — consumers via barrel | All 4 consumers import from `'../class-colors'` or `'../../class-colors'`: `DetectionClasses.tsx`, `CanvasEditor.tsx`, `AnnotationsSidebar.tsx`, `AnnotationsPage.tsx` | `rg "from.*classColors" src` returns no path-style imports |
+| AC-3 — STC-ARCH-01 zero exemptions | `ARCH_IMPORTS_EXEMPT_RE = null` in `scripts/check-arch-imports.mjs`; scanner skips the exemption branch when null; `class-colors` added to `COMPONENT_DIRS` so deep imports into the new component are caught | `node scripts/check-arch-imports.mjs --mode=arch-imports` exits 0; `tests/architecture_imports.test.ts` has new "AC-4: FAILS when a deep import bypasses the class-colors barrel" fixture instead of the exemption-WORKS one |
+| AC-4 — build no circular warnings | `bun run build` — 198 modules transformed, built in 3.83s; no "Circular dependency" warnings involving class-colors / annotations / DetectionClasses | Build log inspected; only pre-existing CSS/chunk-size warnings remain |
+| AC-5 — full suite green | `bunx vitest run` — 31 files / 231 passed / 13 skipped (quarantines unchanged) | Test output captured |
+| AC-6 — docs consistent | `module-layout.md` Layout Rule #2/#3 + Per-Component Mapping (`11_class-colors`, `06_annotations`, `03_shared-ui`) + `## Shared / Cross-Cutting` + Verification Needed #1/#3 updated; `11_class-colors/description.md` Caveats §7 + Module Inventory updated; `architecture_compliance_baseline.md` F3 marked CLOSED with task ref + F4 carry-forward exemption note retired; `06_annotations/index.ts` carry-over comment block removed; `scripts/run-tests.sh` description block updated; `04_verification_log.md` open questions #1 and #8 marked RESOLVED (adjacent hygiene) | `rg "F3-pending\|physical location pending refactor\|EXCEPT classColors" _docs scripts src` returns nothing |
+
+**Constraints**:
+- C1 atomic move + import update: single batch / single commit ✓
+- C2 directory name kebab-case `src/class-colors/` (not `src/classColors/` or `src/shared/class-colors/`) ✓ — opens neither F6 design nor a camelCase outlier
+- C3 barrel re-exports all 4 public symbols (`getClassColor`, `getPhotoModeSuffix`, `getClassNameFallback`, `FALLBACK_CLASS_NAMES`) ✓
+- C4 understood the `EXEMPT_RE` shape before editing — replaced with `null` + a guarded `if (ARCH_IMPORTS_EXEMPT_RE && …)` so the scanner stays single-purpose ✓
+
+No spec-gap findings.
+
+## Phase 3: Code Quality
+
+- **SOLID / SRP**: `src/class-colors/classColors.ts` is a pure-function module with one responsibility (class color/name/PhotoMode fallback); barrel `index.ts` is the standard 5-line re-export pattern.
+- **No behaviour change**: `classColors.ts` is byte-for-byte identical to the prior file (same palette, same fallback names, same functions). Diff is path-only.
+- **Comment cleanup**: the 7-line "classColors symbols are NOT re-exported here" carry-over block was removed from `src/features/annotations/index.ts` — now down to the surviving `CanvasEditor` cross-feature note (still warranted per F2).
+- **Test fixture upgrade**: the replacement architecture test asserts the *stronger* contract (deep import into the new component fails), retaining regression coverage instead of just deleting the fixture.
+
+No findings.
+
+## Phase 4: Security Quick-Scan
+
+- No secrets, no SQL, no eval / exec. Pure file move.
+- No new external inputs.
+
+No findings.
+
+## Phase 5: Performance
+
+- Bundle composition shifts by one chunk boundary; tree-shaking preserves the same set of exported symbols. Build size dist/assets/index-*.js: 923.59 kB (290.56 kB gzip) — within ±0.05% of pre-change baseline.
+
+No findings.
+
+## Phase 6: Cross-Task Consistency
+
+Single-task batch — N/A.
+
+## Phase 7: Architecture Compliance
+
+| Check | Result |
+|-------|--------|
+| Layer direction | `src/class-colors/` is Layer 0; consumers in Layer 2 (`03_shared-ui`) and Layer 3 (`06_annotations`) import downward — allowed |
+| Public API respect | All 4 consumers go through `src/class-colors/index.ts` barrel; STC-ARCH-01 has zero exemptions |
+| New cyclic deps | None — the original concern (re-export through `06_annotations` barrel creates cycle) is structurally gone now that class-colors is its own component |
+| Duplicate symbols | None |
+| Cross-cutting in component dir | Class-colors is correctly its own component; not buried inside an unrelated feature dir |
+
+`COMPONENT_DIRS` in `scripts/check-arch-imports.mjs` was extended with `class-colors` so future contributors who try to deep-import past the barrel are caught — symmetric to every other component.
+
+### Baseline Delta
+
+| Status | Finding | Notes |
+|--------|---------|-------|
+| Resolved | F3 — Physical / logical owner split for `classColors.ts` | Marked CLOSED in `architecture_compliance_baseline.md` with this task ref. F4 carry-forward exemption note also retired. |
+| Carried over | F2, F5, F6, F8 (others outside this file's scope) | Untouched |
+| Newly introduced | (none) | — |
+
+## Verdict
+
+**PASS** — no Critical / High / Medium / Low findings. All 6 ACs covered with explicit evidence; constraints honored; static + fast suites green (231 / 13 skipped); build green with zero circular-import warnings; F3 closed and the 5-coupled-places carry-over surface fully retired.
