Batch Report

Batch: 16 Cycle: 4 (autodev existing-code Step 10) Tasks: [AZ-512] Date: 2026-05-13 Reactivation context: AZ-512 was deferred to backlog at the end of cycle 3 (Cross-Workspace Verification BLOCKING gate failed — admin/ service does not expose /classes write routes). User authorized Option B (MSW-stubbed UI ahead of admin/ AZ-513 shipping) at cycle 4 entry. Task moved backlog/ → todo/ in commit ef56d9c.

Task Results

Task	Status	Files Modified	Tests	AC Coverage	Issues
AZ-512_admin_edit_detection_class	Done	5 production + test + 1 doc	12 passed	8/8 ACs covered	1 noted (pre-existing)

Files modified

Path	Type	Change
src/features/admin/AdminPage.tsx	OWNED (08_admin)	Added inline edit affordance: editingId / editForm / editError / editSaving state; handlers (handleStartEdit, handleCancelEdit, handleUpdateClass, handleEditKeyDown); colspan row swap when editing; pencil (✎) button on read-only rows. Updated t('admin.classes') → t('admin.classes.title').
src/i18n/en.json	spec-authorized (00_foundation)	Restructured admin.classes from flat string to nested object (title + 6 new keys: edit, save, cancel, nameRequired, maxSizeMustBePositive, updateFailed).
src/i18n/ua.json	spec-authorized (00_foundation)	Ukrainian mirror of the same 7 keys (FT-P-22 parity gate PASS).
tests/msw/handlers/admin.ts	test-infra	Added http.patch('/api/admin/classes/:id', ...) partial-merge handler; existing PUT handler retained (dead code, not introduced by this task).
tests/admin_class_edit.test.tsx	new	12 tests covering AC-1..AC-6, AC-8 (AC-7 covered by static FT-P-22 gate).
tests/destructive_ux.test.tsx	adjacent hygiene	Fixed firstRow.querySelector('button') selector at 3 call sites — my ✎ button became the first button in the row; replaced with Array.from(querySelectorAll('button')).find(b => b.textContent === '×') to deliberately target the delete (×) button. Pre-existing it.fails() semantics preserved.
_docs/02_document/components/08_admin/description.md	spec-authorized (per task Scope.Included)	Recorded edit affordance + PATCH wiring in Internal Interfaces table and External API table; cross-referenced AZ-513 prerequisite.

Files NOT modified (scope discipline)

Path	Reason
src/api/endpoints.ts	Task constraint: reuse existing endpoints.admin.class(id) builder; no new endpoint helper for PATCH (same URL as DELETE).
src/api/client.ts	api.patch() helper already exists.
_docs/02_document/architecture.md	Architecture-level wire-shape table update belongs in Step 13 (Update Docs), not Step 10.
AdminPage delete-confirm wiring	Out of scope (Finding B4 — explicitly excluded per task spec Scope.Excluded).
Settings/Users sections	Out of scope (separate concerns per task spec Scope.Excluded).

AC Test Coverage: All covered (8 of 8)

AC	Test name	Notes
AC-1	renders a pencil button per row	One edit affordance per class row
AC-2	row 1 enters edit mode with name="class-a"; other rows stay read-only + single-row invariant	Seeded values + Risk 3 mitigation
AC-3	Save button → one PATCH with full body, row re-renders, form closes + Enter key inside form behaves like Save	Risk 2 mitigation: full-body always
AC-4	Cancel button → no PATCH; row reverts + Escape key inside form behaves like Cancel	No network in either path
AC-5	empty name → no PATCH; nameRequired error visible + non-positive maxSizeM → no PATCH; maxSizeMustBePositive error visible	Validation-before-submit
AC-6	PATCH 500 → form stays open; updateFailed error visible; no alert() called	Risk 4 mitigation: disabled buttons during PATCH; spy on window.alert
AC-7	(static) FT-P-22 (key parity): PASS	scripts/check-i18n-coverage.mjs --parity-only
AC-8	Add posts to /api/admin/classes and refetches the list + Delete sends DELETE and removes the row optimistically	Regression guards

Code Review Verdict: PASS (inline self-review)

A formal /code-review skill run was not invoked for this single-task batch (3 pts, tight scope, all spec ACs verified). The self-review checked: file ownership respected, no silent error swallowing, no alert() usage (STC-SEC7 confirms), no banned-deps literals (STC-SEC1B/C/D confirm), i18n parity + coverage (FT-P-22/23 confirm), architecture compliance (STC-ARCH-01/02 confirm), single-responsibility handlers, no spec drift, no dependencies on un-shipped admin/ work in the test layer.

If a cumulative review is required at Step 14.5 (every K=3 batches), this is the 1st batch of cycle 4 — cumulative review fires at batch 18.

Auto-Fix Attempts: 0

No PASS-with-warnings or FAIL findings during self-review.

Stuck Agents: None

Single task, ~7 file edits, no rewrites without progress. The one i18n-coverage failure (3 raw English aria-labels) was fixed in a single targeted swap (aria-label → data-field) without regressing the spec's aria-label-on-edit-button NFR.

Test Suite Result

Suite	Result
bun run test (full vitest)	32 files passed, 243 tests passed, 13 quarantined skips (cycle 3 baseline preserved)
bash scripts/run-tests.sh --static-only	All 35 static checks PASS including FT-P-22, FT-P-23, STC-ARCH-01/02, STC-SEC1/2/3/4/7/8/13/14, STC-SEC1B/C/D, banned-deps, etc.

Pre-existing bug noted (NOT fixed this batch)

While writing the new test file, I discovered that tests/msw/handlers/admin.ts returns paginate(seedUsers) (= { items, totalCount, page, pageSize }) for GET /api/admin/users, but AdminPage.tsx:19 does api.get<User[]>(...).then(setUsers) expecting a flat array. The catch swallows fetch errors but NOT the subsequent users.map is not a function render error.

• Impact in tests: any test that mounts the full <AdminPage /> without overriding the users handler crashes. Today, destructive_ux.test.tsx:50-59 already overrides /api/admin/users with jsonResponse([]) and documents the drift with the same comment shape; my new tests/admin_class_edit.test.tsx adds the same override (stubUsersAsPlainArray()).
• Impact in production: depends on what the live admin/ service actually returns (flat or paginated). If paginated, the Users table is broken end-to-end against the live service — analogous to the pre-existing AZ-513 add/delete situation. If flat, only the test fixture is wrong.
• Recommendation: a separate UI-workspace ticket to either (a) align the MSW handler with the live admin/ shape (and fix AdminPage.users consumption if needed), or (b) introduce a paginated-response unwrap in the api client. NOT bundled with AZ-512 per scope discipline (coderule.mdc).

Cross-workspace dependency reminder

AZ-512 ships in this batch but the live admin/ service does not yet expose POST | PATCH | DELETE /api/admin/classes(/{id}) (verified 2026-05-13: zero MapPost|MapPatch|MapDelete against classes in admin/Azaion.AdminApi/Program.cs). Per the user-chosen Option B path:

• Step 11 (Run Tests) passes on MSW stubs.
• Step 16 (Deploy) gates on AZ-513 landing on the admin/ workspace AND that build being deployed to whichever environment(s) the UI is promoted into. The leftover record at _docs/_process_leftovers/2026-05-13_az-512-admin-classes-prereq.md remains open until that point.
• The existing pre-existing-broken Add and Delete affordances on AdminPage's class table also start working end-to-end the moment AZ-513 ships.

Next Batch

None planned in this cycle (cycle 4 was entered for AZ-512 reactivation only). After Step 11 (Run Tests) confirms the test suite still passes, autodev auto-chains through Steps 12 → 13 → 14 → 15 → 16 → 17. The Deploy gate (Step 16) will surface the admin/ AZ-513 dependency before any prod cutover.
