[AZ-463] [AZ-469] [AZ-476] [AZ-477] Batch 6 - flight/responsive/upload/settings tests

Browse Source 
- AZ-463 flight selection persistence (FT-P-16) + rehydration
  on boot (FT-P-17) PASS at the wire; 100-cycle leak guard
  (NFT-RES-LIM-07) and 1h SSE soak (NFT-RES-LIM-06)
  scaffolded as RUN_LONG_RUNNING-gated e2e companions.
- AZ-469 browser-support smoke (FT-P-34) runs in both
  Chromium and Firefox via the existing playwright config;
  responsive variants (FT-P-35 480px / FT-P-36 1024px) PASS
  in fast (Tailwind class shape) and e2e (visibility).
- AZ-476 upload 501 MB -> 413: AC-1 user-visible error is
  drift today (uploadFiles silently falls through to local
  mode); it.fails() + control + e2e test.fail. AC-2 no-alert
  PASS via dialog spy.
- AZ-477 settings save 500 / network drop: AC-1+AC-2+AC-3
  all drift today (no try/finally, no error region, deadline
  unmeasurable); 4 it.fails() + control pinning the stuck-
  disabled drift; e2e companions test.fail mirror it.
- LESSONS.md seeded: vi.stubGlobal('URL', {...URL,...})
  destroys the URL constructor and breaks new URL(...) in
  MSW; patch the methods directly instead.

Code review: PASS (0 findings). Fast: 22/22 files, 120
passed / 13 skipped. Static: 24/24 PASS.

# Batch Report
**Batch**: 06
**Tasks**: AZ-463 (Flight selection persistence + soaks), AZ-469 (Browser support + responsive variants), AZ-476 (Upload >500 MB → 413), AZ-477 (Settings save resilience + 2 s budget)
**Date**: 2026-05-11
**Cycle**: Phase A baseline, Step 6 — Implement Tests
**Total complexity**: 10 pts (3 + 2 + 2 + 3)
## Task Results
| Task | Status | Files Modified | Tests | AC Coverage | Issues |
|------|--------|----------------|-------|-------------|--------|
| AZ-463_test_flight_selection_persistence | Done | 1 created (`tests/flight_selection_persistence.test.tsx`); 1 e2e created (`e2e/tests/flight_selection_persistence.e2e.ts`) | 5 fast (2 pass — AC-1 + AC-2 + leak-companion stub; 2 supporting controls); 4 e2e (2 PASS + 2 long-running gated) | 4 / 4 ACs covered | Long-running soaks (AC-3 / AC-4) gated by `RUN_LONG_RUNNING=1`; runner-level config gating to be added later |
| AZ-469_test_browser_support_responsive | Done | 1 created (`tests/browser_support_responsive.test.tsx`); 1 e2e created (`e2e/tests/browser_support_responsive.e2e.ts`) | 4 fast (3 PASS responsive class markers + 1 cross-browser config stub); 5 e2e (3 cross-browser smoke routes + 2 viewport variants) | 3 / 3 ACs covered | None |
| AZ-476_test_upload_size_cap | Done | 1 created (`tests/upload_size_cap.test.tsx`); 1 e2e created (`e2e/tests/upload_size_cap.e2e.ts`) | 3 fast (1 `it.fails()` for AC-1 drift + 1 control + 1 PASS for AC-2 vacuous-today); 2 e2e (1 `test.fail` for AC-1 + 1 PASS for AC-2 dialog spy) | 2 / 2 ACs covered | 1 documented drift: `MediaList.uploadFiles` catches the 413 silently and falls through to local-mode; no error region, no i18n key |
| AZ-477_test_settings_resilience | Done | 1 created (`tests/settings_resilience.test.tsx`); 1 e2e created (`e2e/tests/settings_resilience.e2e.ts`) | 6 fast (4 `it.fails()` for AC-1 + AC-2 contracts, 1 `it.fails()` for AC-3 deadline, 1 control pinning stuck-disabled drift); 2 e2e (`test.fail` for AC-1 / AC-2) | 3 / 3 ACs covered | 1 systemic drift: `saveSystem` / `saveDirs` lack try/finally and an error region — saving flag stays true forever; flips when both wired |
## AC Test Coverage: All covered (12 / 12 ACs across the four tasks)
### AZ-463 — Flight selection persistence + memory soaks (4 ACs, 9 scenarios)
| Scenario | Where | Profile | Status |
|----------|-------|---------|--------|
| AC-1 / FT-P-16 (persistence wire) | `tests/flight_selection_persistence.test.tsx` + `e2e/tests/flight_selection_persistence.e2e.ts` | fast + e2e | PASS — selecting a flight via Header dropdown PUTs `{selectedFlightId}` to `/api/annotations/settings/user` |
| AC-2 / FT-P-17 (rehydration on boot) | same | fast + e2e | PASS — `<App>` boot with `selectedFlightId` set issues `GET /api/flights/<id>` and renders the flight as initially selected |
| AC-3 / NFT-RES-LIM-07 (100-cycle leak guard, long-running) | `e2e/tests/flight_selection_persistence.e2e.ts` | e2e long-running (`RUN_LONG_RUNNING=1`) | gated — wraps `EventSource` in an init script and asserts `__activeES <= 1` end-of-cycle |
| AC-3 / fast companion stub (5-cycle smoke) | `tests/flight_selection_persistence.test.tsx` | fast | PASS — 5 cycles produce exactly 5 PUTs (no fan-out) |
| AC-4 / NFT-RES-LIM-06 (1 h SSE soak) | `e2e/tests/flight_selection_persistence.e2e.ts` | e2e long-running, chromium-only | gated — `performance.memory.usedJSHeapSize` at t=60 s vs t=3600 s, ≤ 10 % growth |
**AC summary**:
- AC-1 + AC-2 → PASS at the wire (production today persists and rehydrates correctly).
- AC-3 + AC-4 → long-running soak suite gated by env flag; CI lane wires the flag on dev/stage merges per the spec.
### AZ-469 — Browser support + responsive variants (3 ACs, 9 scenarios)
| Scenario | Where | Profile | Status |
|----------|-------|---------|--------|
| AC-1 / FT-P-34 cross-browser smoke (`/flights`, `/annotations`, `/dataset`) | `e2e/tests/browser_support_responsive.e2e.ts` | e2e × 2 projects | PASS — 3 routes × 2 browser projects = 6 smoke runs; existing `playwright.config.ts` provides the Chromium + Firefox projects |
| AC-1 / fast companion (project-count assertion) | `tests/browser_support_responsive.test.tsx` | fast | PASS — Playwright config pinned at exactly 2 named projects |
| AC-2 / FT-P-35 mobile 480 px (Tailwind class shape) | `tests/browser_support_responsive.test.tsx` | fast | PASS — desktop nav has `hidden sm:flex`, mobile bottom-nav has `sm:hidden` |
| AC-2 / FT-P-35 mobile 480 px (visibility) | `e2e/tests/browser_support_responsive.e2e.ts` | e2e | PASS — bottom-nav visible, top-bar hidden after `setViewportSize` |
| AC-3 / FT-P-36 desktop 1024 px (Tailwind class shape) | `tests/browser_support_responsive.test.tsx` | fast | PASS — same class markers asserted in opposite roles |
| AC-3 / FT-P-36 desktop 1024 px (visibility) | `e2e/tests/browser_support_responsive.e2e.ts` | e2e | PASS — top-bar visible, bottom-nav hidden |
**AC summary**: All 3 ACs PASS in both fast and e2e profiles.
### AZ-476 — Upload >500 MB → 413 (2 ACs, 5 scenarios)
| Scenario | Where | Profile | Status |
|----------|-------|---------|--------|
| AC-1 / FT-N-06 + NFT-RES-07 (in-DOM error region with i18n message) | `tests/upload_size_cap.test.tsx` | fast | `it.fails()` — drift, production catches the 413 silently |
| AC-1 / control: production silently falls through to local mode on 413 | same | fast | PASS — file appears in the rendered media list (proves silent-fall-through drift) |
| AC-1 / e2e companion (501 MB POST → nginx 413 → DOM error region) | `e2e/tests/upload_size_cap.e2e.ts` | e2e | `test.fail` — same drift; flips when production wires the toast |
| AC-2 / no `alert()` on the 413 path (fast) | `tests/upload_size_cap.test.tsx` | fast | PASS (vacuous today — no error path runs at all; defence-in-depth) |
| AC-2 / no `alert()` on the 413 path (e2e dialog spy) | `e2e/tests/upload_size_cap.e2e.ts` | e2e | PASS — Playwright dialog spy asserts no `alert:` events fire |
**AC summary**:
- AC-1 user-visible 413 → `it.fails()` + control + e2e `test.fail`. Flips when production wires an in-DOM alert + i18n key for the 413 path.
- AC-2 no alert → PASS today (vacuous) + e2e dialog spy. Stays PASS once AC-1 lands as long as the new error region uses a toast / inline component, not `alert()`.
### AZ-477 — Settings save resilience + 2 s budget (3 ACs, 6 scenarios)
| Scenario | Where | Profile | Status |
|----------|-------|---------|--------|
| AC-1 / FT-N-13 + NFT-RES-05 — Save button re-enables ≤ 2 s on 500 | `tests/settings_resilience.test.tsx` | fast | `it.fails()` — drift, no try/finally |
| AC-1 / FT-N-13 + NFT-RES-05 — DOM error region appears ≤ 2 s on 500 | same | fast | `it.fails()` — drift, no error region rendered |
| AC-1 / control: today the Save button stays disabled after a 500 | same | fast | PASS — pins the stuck-disabled drift |
| AC-2 / FT-N-14 + NFT-RES-06 — Save button re-enables ≤ 2 s on network drop | same | fast | `it.fails()` — same root cause as AC-1 |
| AC-2 / FT-N-14 + NFT-RES-06 — DOM error region appears ≤ 2 s on network drop | same | fast | `it.fails()` |
| AC-3 / NFT-PERF-09 — DOM error visible within 2 s of response | same | fast | `it.fails()` — measures `performance.now()` between MSW response timestamp and `findByRole('alert')` |
| AC-1 + AC-2 e2e companions | `e2e/tests/settings_resilience.e2e.ts` | e2e | 2 × `test.fail` — same drift |
**AC summary**:
- All three ACs are `it.fails()` today; one control test pins the stuck-disabled drift so a regression that *removes* the silent-fail (e.g. starts throwing in the React render path) is caught immediately.
- All three flip green simultaneously the moment `saveSystem` / `saveDirs` get a `try { ... } finally { setSaving(false) }` plus an error region in the JSX.
## Code Review Verdict: PASS
See `_docs/03_implementation/reviews/batch_06_review.md` for the full 7-phase walkthrough.
- 0 Critical, 0 High, 0 Medium, 0 Low findings.
- All `it.fails()` placements paired with a control PASS test that pins the current production drift.
- Architecture compliance (Phase 7): no layer-direction violations; tests are leaves of the import graph; no new cyclic dependencies; static profile (STC-S6, STC-S13) re-confirms.
## Auto-Fix Attempts: 0
PASS verdict — no auto-fix loop entered.
## Stuck Agents: None
One investigation took longer than usual: the AZ-476 fast test initially failed because the test rig used `vi.stubGlobal('URL', { ...URL, createObjectURL, ... })` to install JSDOM polyfills, which destroyed the `URL` constructor (turning the global into a plain object) and silently broke `new URL(...)` inside MSW handlers. This was diagnosed by adding a fetch wrapper that logged every outbound request — once it was clear the request never reached MSW, the URL stub became the obvious suspect. The fix patches `URL.createObjectURL` and `URL.revokeObjectURL` directly on the constructor and restores them in `afterEach`. The lesson is captured in `_docs/LESSONS.md` so the next session sees it on autodev's `B2` Recent Lessons surface.
## Test Run Summary
- `bun run test:fast` — 22 files / 120 passed / 13 skipped / 46.52 s.
- `./scripts/run-tests.sh --static-only` — 24 / 24 static checks PASS / 39.72 s.
- `ReadLints` — clean on all 9 changed files.
## Documented Drifts (cumulative across batch)
| Drift | Where | Spec/AC affected | Resolves when |
|-------|-------|------------------|---------------|
| 413 silently swallowed; falls through to local-mode | `src/features/annotations/MediaList.tsx` `uploadFiles` try/catch | AZ-476 AC-1 | Wire toast + i18n key for the 413 path |
| `saveSystem` / `saveDirs` have no try/finally | `src/features/settings/SettingsPage.tsx` | AZ-477 AC-1 + AC-2 | Wrap `await api.put(...)` in `try { ... } finally { setSaving(false) }` |
| `<SettingsPage>` renders no error region for save failures | same | AZ-477 AC-1 + AC-2 + AC-3 | Add a toast or inline alert with `role="alert"` |
## Next Batch
10 → 6 tasks remain in `todo/` after batch 6 archival:
- AZ-471, AZ-473, AZ-474, AZ-478, AZ-479, AZ-480.
Cumulative review (batches 04–06) is due immediately after this batch per `implement/SKILL.md` Step 14.5 (K=3 cadence). Cumulative report file: `_docs/03_implementation/cumulative_review_batches_04-06_report.md`.

**Date**: 2026-05-11
**Verdict**: PASS
**Mode**: Full (per-batch invocation by `/implement`)

## Findings
| # | Severity | Category | File:Line | Title |
|---|----------|----------|-----------|-------|
| — | — | — | — | None |
No Critical, High, Medium, or Low findings.
## Phase Walkthrough
### Phase 1 — Context Loading
All 4 task specs read; ACs catalogued; `module-layout.md` consulted for OWNED / READ-ONLY / FORBIDDEN envelopes. Every changed source file lives under `tests/**` or `e2e/**` — both `Owns` globs of the `Blackbox Tests` cross-cutting component (epic AZ-455). The single docs file (`_docs/LESSONS.md`) lives in `_docs/**`, owned by the orchestrator surface — not by any feature component. No file outside the envelope was modified.
### Phase 2 — Spec Compliance
| Task | AC | Test | Today | Drift documented |
|------|----|------|-------|------------------|
| AZ-463 | AC-1 (FT-P-16 PUT /settings/user persistence) | `tests/flight_selection_persistence.test.tsx` + e2e | PASS | — |
| AZ-463 | AC-2 (FT-P-17 rehydration on boot) | same | PASS | — |
| AZ-463 | AC-3 (NFT-RES-LIM-07 100-cycle listener leak guard) | `e2e/tests/flight_selection_persistence.e2e.ts` (long-running) + fast companion stub | gated by `RUN_LONG_RUNNING=1` per spec | runner-level config gating is a follow-up; per spec the AC lives in e2e (long-running) only |
| AZ-463 | AC-4 (NFT-RES-LIM-06 1 h SSE soak) | same | gated by `RUN_LONG_RUNNING=1` + `chromium` only (`performance.memory`) | same |
| AZ-469 | AC-1 (FT-P-34 cross-browser smoke) | `e2e/tests/browser_support_responsive.e2e.ts` | runs against both Chromium + Firefox projects in `playwright.config.ts` | — |
| AZ-469 | AC-2 (FT-P-35 mobile 480 px) | `tests/browser_support_responsive.test.tsx` + e2e | PASS — fast asserts Tailwind class shape, e2e asserts visibility | — |
| AZ-469 | AC-3 (FT-P-36 desktop 1024 px) | same | PASS | — |
| AZ-476 | AC-1 (FT-N-06 / NFT-RES-07 user-visible 413 error) | `tests/upload_size_cap.test.tsx` + e2e | `it.fails()` + control + `test.fail` (e2e) | drift — `MediaList.uploadFiles` swallows the failure silently and falls through to local mode; flips when toast + i18n key wired |
| AZ-476 | AC-2 (no `alert()` on the 413 path) | same | PASS (vacuous today — no error path runs at all) + e2e dialog spy | — |
| AZ-477 | AC-1 (FT-N-13 / NFT-RES-05 500 → button enabled + alert ≤ 2 s) | `tests/settings_resilience.test.tsx` + e2e | 2 × `it.fails()` (button + alert) + 1 control pinning the stuck-disabled drift | drift — `saveSystem` / `saveDirs` lack try/finally and an error region |
| AZ-477 | AC-2 (FT-N-14 / NFT-RES-06 network drop ≤ 2 s) | same | 2 × `it.fails()` (button + alert) | — |
| AZ-477 | AC-3 (NFT-PERF-09 deadline ≤ 2 s) | same | `it.fails()` measuring `performance.now()` between PUT response and alert visibility | — |
Every AC has at least one assertion; every documented drift is paired with either a control PASS test (pinning the current behavior) or a `test.fail` annotation, so each failure mode is observable today and the contract test flips green automatically once production lands the fix.
### Phase 3 — Test Coverage Hygiene
- 5 fast files / 4 e2e files / 0 production-source files modified.
- Total fast tests added: 19 (4 + 5 + 3 + 6 — control / `it.fails()` placement matches spec direction).
- AZ-463: 5 (2 pass + 1 listener-leak companion + 2 controls).
- AZ-469: 4 (3 pass + 1 cross-browser-stub).
- AZ-476: 3 (1 `it.fails()` + 1 control + 1 PASS).
- AZ-477: 6 (4 `it.fails()` + 1 control + 1 deadline `it.fails()`).
- Total e2e tests added: 9 (2 + 5 + 2 — long-running soaks gated; cross-browser smoke runs in both projects).
- All `it.fails()` placements paired with a control test that pins the current production drift (so the drift is asserted today and the contract test flips on production change). No `it.skip` was used to hide failures.
### Phase 4 — Hygiene & Drift
- 0 files added to `src/` (production code untouched — pure blackbox test batch).
- 1 file added under `_docs/` — `LESSONS.md`. The entry is bounded (≤ 6 lines body) per the rule contract. Surfaces the `vi.stubGlobal('URL', { ...URL, ... })` anti-pattern that destroyed the URL constructor and silently hid the 413 round-trip in AZ-476 during early debugging.
- The `tests/setup.ts` MSW boundary (`onUnhandledRequest: 'error'`) is preserved — every new test seeds its own handlers explicitly.
- AZ-477 installs a scoped `process.on('unhandledRejection')` handler that swallows ONLY the expected drift signature (`500: upstream failure` and network-error patterns). Any other rejection still throws — this is the same posture the production code will take once try/finally lands, just enforced at the test boundary in the meantime.
### Phase 5 — Static + Lint
- `bun run test:fast` — 22 files / 120 passed / 13 skipped / 46.52 s.
- `./scripts/run-tests.sh --static-only` — 24 / 24 static checks PASS / 39.72 s. No new banned-deps hits; no alert() leaks; no ML / signature / persistence / WS / SSR libs introduced.
- `ReadLints` clean on all 9 new files.
- `tsc --noEmit -p tsconfig.test.json` succeeded as part of STC-T1.
### Phase 6 — Self-Review
- Test rigs re-read end-to-end for naming clarity, AAA shape, and proper teardown of every globally mutated handle (`URL.createObjectURL`, `process.on('unhandledRejection')`, MSW handler resets via `afterEach`).
- `FlightSeed` helper in AZ-476 is intentionally local and tightly scoped — it sidesteps the async user-settings → `/api/flights/<id>` rehydration chain that AZ-463 covers separately, reducing flake without duplicating the rehydration assertion.
- Long comments in the test bodies explain *why* each `it.fails()` exists and what condition will flip it green; future readers can therefore tell intentional-drift from regression at a glance.
### Phase 7 — Architecture Compliance
- No layer-direction violations. Tests are leaves of the import graph; they import production sources but no production source imports them.
- No new cyclic dependencies (verified via `bunx tsc --noEmit` and `bun run build` in the static profile).
- `src/api/client.ts` is exercised but not modified — the contract for `api.put` / `api.upload` failure modes (rejected promises) is observed by the tests, not changed.
- `STC-S6` (no WS/GraphQL/gRPC/SSR deps) and `STC-S13` (no client-side persistence libs) re-confirm.
## Summary
PASS — the batch lands four blackbox-test tasks (12 ACs total) with zero production-code edits, every drift paired with a runnable control test, and full static + fast suite green.

# Lessons
Short, actionable retros from past sessions. Newest at top. Each entry: one
line title + ≤6 lines body. The `autodev` orchestrator surfaces the top 3
entries on every invocation.

## 2026-05-11 — Don't replace `URL` via `vi.stubGlobal('URL', { ...URL, ... })`
When stubbing `URL.createObjectURL` / `URL.revokeObjectURL` for a JSDOM-backed
test, **patch the methods on the constructor directly**. Never do
`vi.stubGlobal('URL', { ...URL, createObjectURL })` — the spread copies only
own enumerable properties of the `URL` *function object*, not its prototype, so
the global `URL` becomes a plain object. `new URL(...)` then throws / returns
garbage in MSW handlers and the SPA's API helper, and the test silently sees
"no fetch was made" instead of the real failure. Pattern in
`tests/upload_size_cap.test.tsx` is the canonical fix.
