annotations v2: redesign

Reskin to v2 surface/accent tokens + JetBrains Mono headings to match
_docs/ui_design/v2/plugin/annotations.html. Add scrubber with class-colored
annotation marks, canvas top bar (zoom/cursor/dims), floating AI-detection
banner, multi-band gradient rows in the annotations sidebar, class-distribution
summary footer, and DOM-overlay bbox labels with affiliation icon + readiness
dot. Split VideoPlayer chrome out into the page-level controls row
(transport/frame-step/save/delete/AI-detect/mute/volume) and a new Scrubber
component; player events replace 200ms polling.

Other:
- Auth dev bypass via VITE_DEV_AUTH_BYPASS (gated on import.meta.env.DEV).
- Mount SavedAnnotationsProvider in App so AnnotationsPage doesn't crash.
- Extract hexToRgba to src/class-colors and time helpers to
  src/features/annotations/time.ts (dedup across CanvasEditor / Sidebar /
  AnnotationsPage).
- CanvasEditor: shallow-compare label chips before commit, NaN-guard
  annotation-time parser, cancel cursor RAF on unmount.
- AnnotationsPage: track AI-banner close timer, push initial volume to the
  <video> on media change, drop the duplicate parent muted state.
- Fixed sidebar widths (resize handles removed per design).

+# Large File Writes — Chunk on Failure
+
+When a `Write` call to a single file fails (timeout, payload limit, "Invalid arguments", or any tool error) and the intended content is large (>~500 lines or >~50 KB), do NOT retry the same monolithic Write. Switch to chunked writes:
+
+1. **First Write** — create the file with header + table of contents (if applicable) + an explicit append marker, e.g.
+
+   ```
+   <!-- INSERTION_POINT do-not-remove-until-final-chunk -->
+   ```
+
+2. **Each subsequent chunk** — use `StrReplace` to replace the marker with `<new content>\n<marker>` so the marker stays at the end. This is idempotent: if a chunk fails, retry it without losing earlier chunks.
+
+3. **Final chunk** — `StrReplace` removes the marker.
+
+## Why
+
+- Tool argument size limits and transient failures hit large monolithic writes hardest. Retrying the same large payload typically fails for the same reason.
+- Chunked writes are recoverable per chunk. The earlier chunks are durable on disk.
+- A unique marker is greppable, visible in diffs, and stops accidental insertion in the wrong place.
+
+## Triggers
+
+- Generated documentation that aggregates per-component content (epics, design docs, multi-section architecture summaries, traceability dumps).
+- Large fixture or test-data files written from a template.
+- Any single-file artifact you can pre-estimate at >~500 lines.
+
+## Do NOT chunk
+
+- Files under ~200 lines — a single `Write` is faster, clearer, and easier to review.
+- Source code files where appending breaks module structure (functions, classes, imports). Split into multiple files instead.
+- Files where ordering of sections is computed late and inserting in the middle is required — use a single `Write` once the full content is known.
+
+## Anti-patterns
+
+- Retrying the same failed monolithic `Write` more than once. Twice is the limit; on the second failure, switch strategies.
+- Using `Shell` with heredoc (`cat <<EOF`) or `echo >>` to append — these bypass the editor diff view and break the StrReplace contract for the next chunk.
+- Embedding the marker so deep inside structured content that a chunk's `StrReplace` becomes ambiguous. Place the marker on its own line at the very end of the file.

If the read-back disagrees → STOP and ASK.

In that mode all tasks keep numeric prefixes and a `Tracker: pending` marker is written into each task header. The state file records `tracker: local`. The mode is NOT silent — the user has been asked and has acknowledged the trade-off.

+Condition (folder fallback): `_docs/tasks/todo/` exists AND contains ≥1 file matching `*.md` excluding files starting with `_` (e.g., `_dependencies_table.md` is excluded by convention).
+
+State-driven: reached by auto-chain from Step 3 when the pre-routing gate detected todo tasks. Inserted **before** the sync skills (Step 4 / 4.5 / 5) by deliberate design: implementing renames + cross-repo edits first means the subsequent sync skills propagate the actual landed state rather than the pre-change state, avoiding a second cycle to fix downstream drift.
+
+**Skip condition**: `_docs/tasks/todo/` is empty, missing, or contains only `_*` files. In that case Step 3.5 is skipped entirely and the cycle proceeds with Step 3's existing drift-based routing.
+
+**Goal**: Execute suite-level implementation tasks — cross-repo concerns (e.g., `autopilot` + `ui` + suite `e2e/` cutover in a coordinated change-set), folder renames (e.g., `git mv flights missions` + `.gitmodules` edit + `_infra/` path refs), and suite-root infrastructure additions (e.g., `_infra/dev/docker-compose.dev.yml`). Per-component implementation work stays in each component's own workspace `/autodev` cycle.
+
+**Why this exists**: the meta-repo's existing sync skills (`monorepo-document`, `monorepo-cicd`, `monorepo-e2e`) only **propagate** changes that already landed. They cannot **execute** a task spec. Without Step 3.5, suite-level tickets like AZ-543 (B4 repo rename) or AZ-506 (new dev compose) have no flow path forward — they require operator action outside autodev.
+
+**Inputs**:
+
+- `_docs/tasks/todo/*.md` (excluding `_*`) — task specs in the existing format (`Task` / `Component` / `Dependencies` / `Acceptance criteria` headers)
+- `_docs/_repo-config.yaml` — `components[].path` list, used to compute the suite-level OWNED envelope (workspace root EXCLUDING any path under a component's folder)
+- `_docs/tasks/_dependencies_table.md` — synthesized by this step if missing (see Procedure)
+- `_docs/tasks/_suite_module_layout.md` — synthesized by this step if missing (see Procedure)
+
+**Procedure**:
+

+    C) Pause — review the tasks before deciding (end session, no state changes)
+   ══════════════════════════════════════
+    Recommendation: A — running implement BEFORE syncs means subsequent
+                    sync skills propagate the post-implementation state.
+                    B is appropriate when tasks are blocked on user input
+                    or external coordination. C when the tasks themselves
+                    need owner clarification before execution.

+   ```
+
+3. **On user A — Pre-flight**:
+
+   a. **Working tree clean check**. Run `git status --porcelain`. If non-empty, surface to the user with a Choose A/B/C identical to the implement skill's prerequisite gate (commit/stash manually; agent commits as `chore: WIP pre-implement`; abort).
+
+   b. **Synthesize `_docs/tasks/_dependencies_table.md`** if missing. Parse each in-scope task's `Dependencies:` field. Write a minimal table of the form:
+
+      ```markdown
+      # Suite-Level Task Dependencies
+
+      | Task ID | Depends on | Notes |
+      |---------|------------|-------|
+      | AZ-XXX  | (none)     | — |
+      | AZ-YYY  | AZ-XXX     | — |
+      ```
+
+      If a task lists a dependency that is neither in `todo/` nor `done/`, log a warning in the synthesized file but do not block — implement skill's Step 1 (Parse) will surface the issue if it actually blocks execution.
+
+   c. **Synthesize `_docs/tasks/_suite_module_layout.md`** if missing. Default content:
+
+      ```markdown
+      # Suite-Level Module Layout (synthetic)
+
+      Generated by autodev meta-repo Step 3.5. The suite root has no per-feature decomposition; ownership is defined at the component-boundary level only.
+
+      ## Per-Component Mapping
+
+      | Component | Owns                             | Imports from |
+      |-----------|----------------------------------|--------------|
+      | suite     | (workspace root) excluding any path listed under `_repo-config.yaml.components[].path` | (read-only) every component's primary doc + `_docs/*.md` |
+
+      Suite-level tasks operate on: `.gitmodules`, `_infra/**`, `_docs/**` (excluding `_docs/tasks/_*` regenerated files), root `README.md`, `e2e/**` (suite e2e harness only).
+
+      Forbidden paths for suite-level tasks: `<component>/**` for every component listed in `_repo-config.yaml.components[].path` — those edits live in the component's own workspace `/autodev` cycle.
+      ```
+
+   d. **Prepare invocation context**:
+
+      ```
+      suite_level: true
+      TASKS_DIR: _docs/tasks/
+      module_layout_path: _docs/tasks/_suite_module_layout.md
+      ```
+
+4. **Invoke implement skill**. Read and execute `.cursor/skills/implement/SKILL.md` with the prepared context. The skill's "Suite-level invocation context" subsection (added in tandem with this flow change) honors the three flags above and skips:
+
+   - Step 14.5 (cumulative code review) — no `architecture_compliance_baseline.md` exists at the suite level; cross-task drift is captured by the next `monorepo-status` cycle instead.
+   - Step 15 (Product Implementation Completeness Gate) — the gate's inputs (`_docs/02_document/architecture.md`, `system-flows.md`, `components/*/description.md`) do not exist in the meta-repo artifact layout. Suite tasks are infrastructure / coordination work, not feature implementation.
+
+   All other implement skill steps (1–14, 16) execute unchanged. Tracker integration (Step 5: In Progress, Step 12: In Testing) runs normally.
+
+5. **Post-implement re-status**. After the implement skill completes (last batch committed, all originally-todo tasks moved to `_docs/tasks/done/`), silently re-run Step 3's drift detection logic — do NOT re-render the full Status report; just re-evaluate the drift signals against the post-implementation tree. Then auto-chain per the post-implementation drift findings:
+
+   - Doc drift → Step 4 (Document Sync)
+   - Suite-e2e drift only → Step 4.5
+   - CI drift only → Step 5
+   - No drift → cycle complete
+
+   Note: the post-implement re-status is exactly why Step 3.5 is placed before sync. A repo rename will typically introduce doc + CI drift; the next invocation of Step 4 / Step 5 catches it on the same cycle.
+
+6. **On user B (skip)** → mark Step 3.5 `skipped` in state file. Apply Step 3's original drift-based routing (compute from the pre-Step-3.5 Status report).
+
+7. **On user C (pause)** → end session. Update state to `step: 3.5, status: in_progress, sub_step: {phase: 0, name: awaiting-task-review, detail: "<N> tasks pending review"}`. Tell the user to invoke `/autodev` again after deciding. **Do NOT modify any files** — pre-flight has not run yet.
+
+**Self-verification** (executed before invoking implement):
+
+- [ ] Working tree is clean (or user explicitly chose B in the WIP-stash sub-Choose)
+- [ ] `_docs/tasks/_dependencies_table.md` exists (synthesized if it didn't)
+- [ ] `_docs/tasks/_suite_module_layout.md` exists (synthesized if it didn't)
+- [ ] All in-scope task files have a `Component:` field (skip + report any that don't — don't guess ownership)
+- [ ] Tracker availability gate satisfied per `protocols.md` (or `tracker: local` previously chosen)
+
+**Failure handling**:
+
+- If implement returns FAILED → standard Failure Handling (`protocols.md`): retry up to 3 times, then escalate.
+- If implement is interrupted mid-batch → next invocation re-detects via the implement skill's resumability protocol (read latest `_docs/03_implementation/suite_batch_*.md`). Step 3.5 itself is reentrant: on re-entry, if `todo/` still has tasks, it presents the Choose again with the remaining set.
+- **Half-applied state risk** (acknowledged): if implement is interrupted between commits, the working tree is clean at the last commit boundary but the in-flight batch is lost. The user is responsible for inspecting and re-invoking. This is intentional — automated rollback of suite-level renames + `.gitmodules` edits is more dangerous than a human-driven recovery.
+
+**Idempotency**: if `_docs/tasks/todo/` becomes empty after this step (all tasks moved to `done/`), the next `/autodev` invocation skips Step 3.5 entirely and proceeds with normal Status → sync flow.

 - **Cyclical, not terminal**: no "done forever" state. Each invocation completes a drift cycle; next invocation starts fresh.
-- **No tracker integration**: this flow does NOT create Jira/ADO tickets. Maintenance is not a feature — if a feature-level ticket spans the meta-repo's concerns, it lives in the per-component workspace.
+- **Tracker integration scope**: this flow does NOT create Jira/ADO tickets in its sync skills (Status / Document Sync / E2E / CICD). Step 3.5 (Suite Implement) IS tracker-integrated — it transitions existing tickets In Progress → In Testing per the implement skill's standard tracker handling. Suite-level tickets are authored manually by the operator (typically as children of an Epic that spans multiple components, like AZ-539); the flow doesn't auto-create them.
+- **Per-component vs. suite-level work**:
+  - Tickets that touch component source code (`<component>/src/**`) belong in that component's own workspace `/autodev` cycle. The meta-repo flow does NOT execute them.
+  - Tickets that touch suite-root paths only (`.gitmodules`, `_infra/**`, suite `e2e/**`, root `README.md`, suite `_docs/**` outside `tasks/_*`) are eligible for Step 3.5.
+  - Tickets that span both (e.g., AZ-550 B11 consumer cutover, which touches `autopilot/`, `ui/`, AND suite `e2e/`) are NOT executable from a single workspace by design — split the ticket so the suite-level slice can run in Step 3.5 and the component slices run in their owning workspaces.
 - **Onboarding is opt-in**: never auto-onboarded. User must explicitly request.
 - **Failure handling**: uses the same retry/escalation protocol as other flows (see `protocols.md`).

+### Suite-level invocation context (meta-repo flow)
+
+When invoked from `.cursor/skills/autodev/flows/meta-repo.md` Step 3.5 (or any caller that supplies the same context envelope), the skill receives:
+
+```
+suite_level: true
+TASKS_DIR: <override>          # e.g., _docs/tasks/  (vs. default _docs/02_tasks/)
+module_layout_path: <override>  # e.g., _docs/tasks/_suite_module_layout.md
+```
+
+When `suite_level: true` is present, the following gate adjustments apply — and ONLY these. All other steps (1–14, 16) execute unchanged:
+
+1. **TASKS_DIR override** is honored throughout the skill (Step 1 Parse, Step 13 Archive, Step 15 input paths if it ran). Default `_docs/02_tasks/` is replaced by the supplied path.
+2. **module_layout_path override** is read instead of the hardcoded `_docs/02_document/module-layout.md` in Step 4 (Assign File Ownership). The supplied file uses the same `Per-Component Mapping` schema. If both the override and the hardcoded path are missing, behavior is unchanged from default mode (STOP and instruct).
+3. **Step 14.5 (Cumulative Code Review) — SKIPPED**. The meta-repo has no `_docs/02_document/architecture_compliance_baseline.md`; cross-task drift is captured by the next `monorepo-status` cycle instead.
+4. **Step 15 (Product Implementation Completeness Gate) — SKIPPED**. The gate's hard inputs (`_docs/02_document/architecture.md`, `system-flows.md`, `components/*/description.md`) do not exist in the meta-repo artifact layout. Suite-level tasks are infrastructure / coordination work (renames, cross-repo edits, suite-root infra additions), not feature implementation; the equivalent completeness signal is the next `monorepo-status` drift report (which the meta-repo flow re-runs immediately after Step 3.5 returns).
+5. **Final report filename**: `_docs/03_implementation/suite_implementation_report_{run_name}.md` (in addition to the existing feature/test/refactor variants). Batch reports follow `_docs/03_implementation/suite_batch_{NN}_report.md`.
+6. **Tracker integration** (Step 5: In Progress, Step 12: In Testing) runs unchanged — suite-level tickets follow the same tracker rules as any other.
+
+Without `suite_level: true`, none of these adjustments apply and the skill runs exactly as documented in default mode.

+
+## Cycle-4 deployment-doc deltas (NOT written this cycle)
+
+In strict autodev terms, Step 16 in this cycle was a real cutover (option A), not a planning sync. The cycle-2 pattern of patching `_docs/02_document/deployment/*` was therefore skipped here because:
+
+- AZ-512 introduced **no** changes to Dockerfile, `.woodpecker/`, env vars, or `nginx.conf` (verified inline during Step 14 security audit; the cycle-4 delta `security_report_cycle4_delta.md` enumerates the changed files).
+- AZ-512's only wire-shape change is one new HTTP method on an existing URL (`PATCH /api/admin/classes/{id}` — already routed to `admin/` by `nginx.conf` since cycle 2 because `DELETE /api/admin/classes/{id}` was already proxied through the same route block).
+- No new env vars, no new container, no new exposed port.
+
+If a future cycle adds env vars, infra changes, or new services, the cycle-2 planning-sync pattern (update `environment_strategy.md`, `ci_cd_pipeline.md`, `containerization.md`, `observability.md`) should be applied.
+
+## Verification
+
+- `git push origin dev` for `ui/` returned `09449bd..8737491  dev -> dev` (4 commits, fast-forward).
+- `git status -sb` for `ui/` confirms `dev` and `origin/dev` are synced post-push (no `[ahead N]`).
+- Functional test suite green pre-push (243 passed, 13 quarantined skips, 0 failed — see `test-output/summary.csv` and `test-output/fast-report.xml`). Up +12 vs cycle 3 from the new `tests/admin_class_edit.test.tsx` suite.
+- Static perf NFT-PERF-01 green pre-push (291 332 B gzipped vs ≤ 2 097 152 B threshold — see `test-output/performance-summary.txt` and `_docs/06_metrics/perf_2026-05-13_cycle4.md`).
+- Security cycle-4 delta verdict PASS_WITH_WARNINGS pre-push (see `_docs/05_security/security_report_cycle4_delta.md`).
+- No nginx/Docker/CI config changes in cycle 4.
+- Cross-workspace deploy gate (AZ-513) explicitly acknowledged and re-recorded in this report and in the leftover entry. The deployed UI on `ui/` dev will return `admin.classes.updateFailed` on real PATCH attempts until `admin/` AZ-513 ships — by design under user-authorized Option B.
+
+## Cycle-3 → cycle-4 push-scope progression
+
+Cycle 3 deploy gate: user picked option A (ui/ dev only). Cycle 4 deploy gate: user picked option A again (ui/ dev only). The same trade-off applies — stage/prod cutover is being collected for a single later promotion. Two consecutive cycles of dev-only pushes means the eventual stage promotion will batch AZ-510 + AZ-511 + AZ-512 deltas into one stage build, with the additional gate that AZ-513 must have shipped in admin/ by that time (otherwise the AZ-512 edit feature renders but cannot complete saves).

+| **Total (de-duplicated)** | **9** | (cycle 1 close: 0 → cycle 2 close: 3 → cycle 3 close: 7 → cycle 4 close: **9**) |
+
+> Trajectory continues: 0 → 3 → 7 → **9**. Net growth +2 this cycle (cycle 4 added D-CY4-STAGE + D-CY4-MAIN; AZ-513 re-opened as `cross-workspace prerequisite`; D-CY4-ADMIN-PUSH was carried-not-added because the user kept the same dev-only push scope as cycle 3). Cycle-3 retro Improvement Action #3 (track backlog as first-class metric) is now being applied — but the drain mechanism (step-0 sweep that closes items, not just notices them) is still pending. **Backlog growth is decelerating** (+3, +4, **+2**); even so, the gap between accumulated and drained remains the dominant signal.
+
+### User-decision points (cycle 4 only)
+
+- Cycle-4 entry: user **explicitly overrode** the cycle-3 conservative-path default for AZ-512 ("implement 512, 513 would be implemented in minutes. You can write mocks for backend data anyway for testing."). The spec was updated to record this as user-authorized Option B; the leftover entry was re-opened with the Option-B rationale. This is the first cross-cycle override of a spec-conservative default in cycles 1-4.
+- Step 13 → Steps 14+15 gate: user chose **D** (run both Security Audit AND Performance Test) — first time across cycles 1-4 that BOTH optional gates ran inline. Cycle 3 also ran both via auto-chain but Step 15 emitted no separate report; cycle 4 produced standalone `perf_2026-05-13_cycle4.md` for the first time.
+- Cycle-4 Step 16 deploy gate: user chose **A** (push to ui/ dev only) — same option as cycle 3. Stage / main / admin/ dev push deferred.
+
+## Trend Comparison
+
+| Trend | Cycle 1 | Cycle 2 | Cycle 3 | Cycle 4 | Direction |
+|-------|---------|---------|---------|---------|-----------|
+| Code review pass rate (formally-reviewed batches) | 100 % | 50 % | 100 % | 100 % (self-review) | held |
+| Test count (cumulative this cycle delta) | +46 | +20 | +2 | **+12** | rebounded from cycle-3 low |
+| Static gate count | +2 | +2 | 0 | **0** | held |
+| Architecture findings open (baseline) | 7 (−2) | 7 (0) | 6 (−1) | **6 (0)** | held flat |
+| STC-ARCH-01 exemptions | 1 | 1 | 0 | **0** | held at zero |
+| Wire-contract assertions | 36 | 36 | 37 (+1) | **37 (0)** | held |
+| Pending USER actions at cycle close | 0 | 3 | 7 | **9** | ⬆ still growing (rate decelerating) |
+| Tasks deferred to backlog at spec gate | 0 | 0 | 1 | **0** | reverted (the cycle-3 deferral was the one reactivated) |
+| Cycles where user overrode a spec-conservative default | 0 | 0 | 0 | **1** (AZ-512 Option B) | new pattern |
+| Bundle (gzipped initial JS, B) | — | 290 465 | 290 575 (+110) | **291 332 (+757)** | growing in line with feature delta; far within budget |
+
+Cycle 4 is the first single-task reactivation cycle (vs cycle 3's three-task fresh cycle). The cycle-3 retro called out that the AZ-512 gate worked as designed; cycle 4 confirms the *other half* of the design: a user-authorized override path can flow through the entire 9→17 step sequence without regressions, while preserving the deploy gate. Both halves of the gate design are now field-validated.
+
+## Top 3 Improvement Actions
+
+1. **Codify a "pre-existing-bug surface lifting" routine — observe-then-document, never silently work-around.**
+   While writing `tests/admin_class_edit.test.tsx`, I discovered the `/api/admin/users` MSW handler's paginated response vs `AdminPage.tsx`'s flat-array expectation by hitting a `users.map is not a function` render crash. The route taken was: document in batch_16_cycle4_report.md "Pre-existing bug noted", apply a local workaround (`stubUsersAsPlainArray()` in `beforeEach`), and recommend filing a separate UI-workspace ticket. This was the right tactical move, but the **systematic routine** is missing — there's no checklist anywhere that says "when a new test mounts a container component, run it once with default fixtures only, name any crashes, and decide explicitly fix-now vs document-and-defer." Without that routine, future cycles will keep accumulating quiet local workarounds and the side-observed bug list grows without a tracking artifact.
+   - Impact: medium — the failure mode (silent test-fixture overrides masking real source bugs) is the test-side analog of "client-side validation only" — looks green, but tested against a fake. Two distinct cycles (3 and 4) already surfaced one bug each through this route.
+   - Effort: low — add a section "Pre-existing-bug surfacing during test writing" to `_docs/02_tasks/_templates/module_scoped_state_introduction.md` (created in cycle 3) and to the implementation skill's batch-report template; require the batch report to either list "Pre-existing bug noted" entries or affirm "None observed; ran with default fixtures only".
+
+2. **Audit test selectors that pick "the button" / "the link" / "the input" without disambiguation, before adding a new affordance to an existing DOM region.**
+   The cycle-4 ✎ edit button was inserted into the same `<td>` that holds the `×` delete button. `tests/destructive_ux.test.tsx` had three call sites using `firstRow.querySelector('button')` — each silently rebound to the new ✎ button instead of the old `×` button, and the tests would have shipped green-but-meaningless if not caught by the test run. The fix was 1-line per site (`Array.from(...).find(b => b.textContent === '×')`). The deeper lesson is that the failure mode is **invisible at code-review time** — a code reviewer reading the source diff has no view into which test selectors will resolve to which DOM element, only the test run reveals it. The cheap structural prevention: before adding a new control to a DOM region, grep the test corpus for `querySelector('button|input|a')` / `getByRole('button')` without name/text disambiguation, in the same file / sibling files, and add disambiguating selectors *in the affordance batch*.
+   - Impact: medium — saves one stabilization loop per affordance addition; the cost of NOT catching it is silent test-meaning-drift in destructive-UX assertions, which is exactly the kind of bug Finding B4 (cycle 1) was filed for.
+   - Effort: low — add a 3-bullet checklist to the implement skill's "Adjacent hygiene" rules: (a) before inserting a new button/input into an existing row/region, grep for non-disambiguated selectors targeting that region; (b) update them in the same commit; (c) if you can't make them disambiguated without changing the source DOM, prefer giving the new control a stable `data-testid` over rewriting test selectors.
+
+3. **Add a "user-action backlog drain rate" to the retrospective metric set.**
+   Cycle 3 retro added "user-action backlog at cycle close" as an absolute count. Cycle 4 now has two consecutive data points (7 → 9). The signal in absolute count is being applied — but the signal that matters for process-shape is the **drain rate**: how many items got closed *this* cycle vs how many got added? Cycle 4: 1 item state-transitioned (L-AZ-512-ADMIN-PREREQ moved from "deferred awaiting AZ-513" to "re-opened under Option B"; technically still open), +2 net new (D-CY4-STAGE, D-CY4-MAIN). So drain = 0, add = 2, net = +2. Tracking drain explicitly will make the drain-mechanism conversation concrete — today the retro just says "backlog is +2, drain mechanism still pending" with no metric to optimize.
+   - Impact: medium — operationalizes cycle-3 Action #3. Makes the drain-mechanism design (which is presumably a step-0 sweep that closes items, not just notices them) measurable from the first cycle it runs.
+   - Effort: low — extend `.cursor/skills/retrospective/SKILL.md` Step 1 metric collection with a "User-action backlog drain rate" subsection (count of items added this cycle vs items closed this cycle vs net change vs absolute close-count), and add to the retrospective-report template.
+
+## Suggested Rule / Skill Updates
+
+| File | Change | Rationale |
+|------|--------|-----------|
+| `.cursor/skills/implement/SKILL.md` (Adjacent Hygiene section) | Add the 3-bullet "test selector audit" checklist for inserting a new control into an existing DOM region. | §Top 3 Improvement Action #2. |
+| `.cursor/skills/implement/templates/batch_report.md` (if it exists) or `_docs/02_tasks/_templates/module_scoped_state_introduction.md` | Add "Pre-existing-bug surfacing during test writing" subsection requirement: batch report must explicitly list observed pre-existing bugs OR affirm "None observed; ran with default fixtures only". | §Top 3 Improvement Action #1. |
+| `.cursor/skills/retrospective/SKILL.md` (Step 1 metrics) | Add **"User-action backlog drain rate"** metric: items added this cycle / items closed this cycle / net delta / absolute close-count; track alongside the absolute count introduced in cycle 3. | §Top 3 Improvement Action #3. |
+| `.cursor/skills/retrospective/templates/retrospective-report.md` | Add a "User-action backlog drain rate" sub-table alongside the absolute table under Efficiency. | §Top 3 Improvement Action #3. |
+| `_docs/LESSONS.md` (top) | Append the 3 lessons in §LESSONS Append below; trim to ≤ 15 entries. | Skill Step 4. |
+
+## Notes — Step 16 outcome
+
+Step 16 (Deploy) ran in **real-cutover mode (option A)** for the second consecutive cycle. Push scope was ui/ `dev` only (4 commits, fast-forward `09449bd..8737491`). The cycle-3 closure commit `eef3bdf` (which had been locally ahead since cycle 3's push) shipped this cycle alongside cycle-4's three commits. Stage / main / admin/ `dev` pushes were deferred at the push-scope sub-gate (user chose option A — ui/ dev only).
+
+- Devices will not auto-pull cycle-3 + cycle-4 changes until `dev → stage → main` completes (D-CY4-STAGE, D-CY4-MAIN).
+- AZ-513 task spec still sits locally on `admin/` `dev` — admin/ team cannot pick it up until D-CY3-ADMIN-PUSH lands (now carried into cycle 5).
+- No Dockerfile / `.woodpecker/` / nginx / env changes in cycle 4 — verified inline by the security audit (Step 14 enumerated the changed-file set as 6 source/test + 5 doc files only).
+- The deployed ui/ dev build will surface `admin.classes.updateFailed` on real edits until AZ-513 ships in admin/ — by design under the user-authorized Option B path.
+
+These items add to the user-action backlog; see §Efficiency → User-action backlog table.
+
+## LESSONS Append (top 3, single-sentence, tagged)
+
+1. **[testing]** When inserting a new control (button, input, link) into an existing DOM row or region that already holds other controls, audit the test corpus *before* the commit for non-disambiguated selectors targeting that region (`querySelector('button')`, `getByRole('button')` without `name`/`text`, indexed `querySelectorAll('button')[0]`) and either update them with disambiguating text/role/name in the same affordance commit or give the new control a stable `data-testid` — otherwise the new control silently rebinds existing assertions to the wrong element and the tests ship green-but-meaningless, exactly as cycle 4's `destructive_ux.test.tsx` did when the AZ-512 ✎ button became the new first button in the class-row action cell.
+
+2. **[testing]** When a new test mounts a container component end-to-end, run it once with the project's default test fixtures only (no per-test override) and explicitly name any natural crashes ("`users.map is not a function`") in the batch report as "Pre-existing bug noted" — never silently apply a local fixture workaround without recording the latent drift, because each silent workaround hides a source-vs-fixture mismatch that future authors will re-encounter as a "mysterious test setup", and cycle 4's `tests/admin_class_edit.test.tsx` was the second cycle to surface one through this route.
+
+3. **[process]** When the user explicitly overrides a spec-conservative cycle-defer decision (the AZ-512 Option B authorization: "implement now, write mocks for backend"), the autodev MUST preserve every downstream gate that the conservative path would have enforced — re-record the override rationale in the leftover entry, keep the cross-workspace deploy gate visible at Step 16, mark the carried tickets distinctly from cycle-internal carries, and surface the override as a first-class retrospective trend ("Cycles where user overrode a spec-conservative default") — so the operating cost of the override stays measurable and the user's downstream visibility is unchanged from the conservative path.

It introduced **no new components**, **no new gates**, **no new barrels**, **no new wire-contract assertions**, and **no new architecture findings**. The structural snapshot is therefore a near-identity copy of cycle 3 close with two non-structural deltas: test count (+12) and bundle size (+757 B).

+- Cycle 5 awaiting next `/autodev` New Task invocation.
+- Leftovers carried into cycle 5 (replay at Step 0):
+  - `2026-05-12_az-498-deploy-and-key-revocations.md` — 3 manual third-party items (UI satellite-provider deploy gate; OWM revoke; Google Geocode revoke).
+  - `2026-05-13_az-512-admin-classes-prereq.md` — re-opened under user-authorized Option B; closes when AZ-513 ships AND deploys in admin/.
+- Cross-workspace status: AZ-513 (admin/) still not implemented. UI's PATCH /api/admin/classes/{id} returns 404 in any env until admin/ ships AZ-513.
+- User-action backlog at cycle-4 close (per retro): 9 items (de-duplicated). +2 vs cycle 3.
+- Pre-existing bug surfaced during AZ-512: `/api/admin/users` MSW shape (paginated) vs `AdminPage` consumption (flat `User[]`). Awaiting separate UI-workspace ticket triage; pre-existing, not introduced by AZ-512.
+- Cycle-3 deferred deploy items still carry: D-CY3-STAGE, D-CY3-MAIN, D-CY3-ADMIN-PUSH. Cycle 4 added: D-CY4-STAGE, D-CY4-MAIN (D-CY4-ADMIN-PUSH not added — user kept same ui/-dev-only scope).
