[AZ-485] Add Public API barrels + STC-ARCH-01 (F4 close)

Closes architecture baseline finding F4. Every component now exposes
its Public API through `src/<component>/index.ts`; cross-component
imports go through the barrel. `scripts/check-arch-imports.mjs` plus
`STC-ARCH-01` in the static profile enforce the rule; tests in
`tests/architecture_imports.test.ts` cover AC-4/AC-5 + 2 exemption
cases. One F3-pending exemption (`classColors`) is documented in 5
places (barrel, consumer, script, doc, test) to avoid a circular
import.

Phase B cycle 1 batch 1 of 2 (epic AZ-447). Batch 2 is AZ-486
(endpoint builders) — blocked on this commit landing.

 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: NO barrel `index.ts` exists at any component root. The only `index.ts` files are `src/types/index.ts` (a re-export hub for type aliases — used as the de-facto public API for `00_foundation` types) and `mission-planner/src/types/index.ts`. Until Step 4 introduces barrels, Public API is approximated as "every named export from any file under the component's owned directories". Cross-component imports ARE happening at file-name granularity (`import { api } from '../api/client'`, `import { CanvasEditor } from '../annotations/CanvasEditor'`).
+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.
 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).

+
+## Design Decisions
+
+1. **Single source of truth for the static check** — `scripts/check-arch-imports.mjs` mirrors the existing `scripts/check-banned-deps.mjs` pattern (AZ-482). The bash function `static_check_no_cross_component_deep_imports` in `scripts/run-tests.sh` is a one-line delegate. The new unit test invokes the script directly with `spawnSync`, so a regex regression in the script trips the test even if the bash glue still reports PASS.
+2. **classColors exemption is structural, not stylistic** — Re-exporting `classColors` symbols through the `06_annotations` barrel creates a runtime circular import (`AnnotationsPage → DetectionClasses → 06_annotations barrel → AnnotationsPage`) that materializes as `FALLBACK_CLASS_NAMES === undefined` inside `DetectionClasses`. The exemption is documented in five places (the barrel file, the consumer file, the static-check script's `EXEMPT_RE` comment, `module-layout.md` Layout Rule #3, and the architecture test) so it cannot be forgotten when F3 lands.
+3. **`10_app-shell` intentionally has no barrel** — The component is a collection of root-level files (`App.tsx`, `main.tsx`, `index.css`, `vite-env.d.ts`) never imported as a unit. STC-ARCH-01's component allowlist (`api|auth|components|features/[a-z-]+|hooks|i18n`) intentionally omits app-shell; the doc records this explicitly.
+4. **Test-file deep-import string concatenation** — `tests/architecture_imports.test.ts` builds its synthetic offending strings via concatenation (`'fr' + 'om'`, `'..' + '/..'`) so the scanner does not flag the test source itself when it walks `tests/`. The fixtures created at runtime go under `tests/_arch_fixtures/` and are torn down in `afterEach`.
+
+## Code Review Verdict: PASS
+
+Self-review (implement skill Step 9 / 10), applied to the 13 new + 17 production + 22 test + 1 runner + 1 doc + 1 script changes:
+
+- **0 Critical, 0 High, 0 Medium, 0 Low findings.**
+- **Scope discipline**: every modified file is one of (barrel author, deep-import consumer, static-check author, doc author). The 4 originally-untracked-and-edited test files (`annotations_endpoint`, `destructive_ux`, `form_hygiene`, `overlay_membership`) are pre-existing committed test files where the only edit is import-path migration.
+- **No silent error suppression**: `check-arch-imports.mjs` writes the full hit list to stderr before exiting non-zero; the bash delegate propagates the exit code; `run-tests.sh` records the failure into the static CSV.
+- **Single-responsibility**: each barrel re-exports its component's documented Public API only. `check-arch-imports.mjs` has one job (detect cross-component deep imports). The new test exercises only that script.
+- **No new dependencies**: `check-arch-imports.mjs` uses Node stdlib (`fs`, `path`, `url`) only. The architecture test uses Vitest + Node stdlib.
+- **Architecture compliance (Phase 7)**: no layer-direction violations introduced; the only cross-feature edge (`07_dataset → 06_annotations` for `CanvasEditor`, F2) is grandfathered exactly as before — `CanvasEditor` is intentionally re-exported through the `06_annotations` barrel so the consumer is barrel-compliant. STC-ARCH-01 confirms no new cyclic dependencies.
+
+## Auto-Fix Attempts: 1
+
+One auto-fix loop entered during Phase 3 (test import migration):
+
+- **Symptom**: `tests/detection_classes.test.tsx` failed with `TypeError: Cannot read properties of undefined (reading 'map')` after `FALLBACK_CLASS_NAMES` was migrated to import through the `06_annotations` barrel.
+- **Diagnosis**: barrel-induced circular import — `AnnotationsPage → DetectionClasses → 06_annotations barrel → AnnotationsPage`. The barrel module evaluated before `classColors` exports were bound, so the symbol resolved to `undefined`.
+- **Fix**: remove `classColors` re-exports from the `06_annotations` barrel, document the F3-pending exemption in five places (see Design Decision #2), point the consumer + the test back at the direct path `src/features/annotations/classColors`.
+- **Validation**: fast profile back to green; STC-ARCH-01 unit test added an exemption case (`AC-4: still PASSES when only the classColors F3-pending exemption is used`) so the carve-out is regression-tested.
+
+## Stuck Agents: None
+
+No multi-pass investigations beyond the auto-fix above.
+
+## Test Run Summary
+
+- `bun run test:fast` (via `bash scripts/run-tests.sh`) — 27 files / 167 passed / 13 skipped / 21.11 s wall (+4 new tests vs Phase A close at 163; 0 regressions).
+- `bash scripts/run-tests.sh --static-only` — 30 / 30 static checks PASS (added `STC-ARCH-01`; no regressions in the existing 29).
+- `node scripts/check-arch-imports.mjs` (direct invocation) — exit 0, stderr empty on the migrated codebase; exit 1 on every synthetic fixture in the architecture test.
+- `ReadLints` — clean on all 13 new files.
+- `git diff --stat` — 41 modified + 13 new files; +113 / -99 net lines; mostly mechanical one-line import path edits.

+| Drift | Where | Spec/AC affected | Resolves when |
+|-------|-------|------------------|---------------|
+| `classColors` symbols cannot flow through the `06_annotations` barrel due to a circular import | `src/features/annotations/index.ts` (export omitted by design); 5 cross-doc mentions | F3 (Medium / Architecture) — `architecture_compliance_baseline.md` | F3 moves `classColors.ts` out of `06_annotations` into its own component directory (`src/shared/classColors.ts` or a dedicated `11_class-colors` directory); F3 closes by adding a `src/<new-home>/index.ts` barrel and removing the STC-ARCH-01 exemption |
+
+(No other drifts surfaced.)
+
+## Phase B Cycle 1 Status
+
+This is **batch 1 of 2** in Phase B cycle 1 (the cycle covers baseline findings F4 + F7 under epic AZ-447). Batch 2 will implement **AZ-486** — endpoint builders in `src/api/endpoints.ts` + `STC-ARCH-02` for hardcoded `/api/<service>/…` paths — which depends on this batch landing first (`endpoints` ships through the new `src/api` barrel; Jira "Blocks" link AZ-485 → AZ-486).
+
+## Next Batch
+
+**AZ-486** (5 pts) — endpoint builders + STC-ARCH-02. Spec already in `_docs/02_tasks/todo/AZ-486_refactor_endpoint_builders.md`.

   - F1 (mission-planner convergence) deliberately not created — needs `/decompose` for 7+ port-group cycles in its own Epic.
-- Step 10 (Implement) starts with AZ-485 — `Blackbox Tests` owns the static-check addition and the `tests/**` import-path migration; production component teams own their barrel files per `module-layout.md`.
+- Step 10 (Implement) batch 9 (AZ-485) done:
+  - 11 new barrels, ~40 production deep imports migrated, ~22 test deep imports migrated.
+  - `scripts/check-arch-imports.mjs` + `STC-ARCH-01` static gate added (mirrors the `check-banned-deps.mjs` pattern).
+  - `tests/architecture_imports.test.ts` covers AC-4 / AC-5 + 2 exemption cases (4 new fast tests; total 167 PASS / 13 SKIP / 0 FAIL).
+  - One F3-pending exemption: `src/features/annotations/classColors` is imported directly (circular-barrel avoidance), documented in 5 places.
+  - Next: AZ-486 (endpoint builders) — depends on AZ-485 commits landing first.
