# AEG-V16-024 — FE accessibility gate

**WBS / Requirement / UI / Test:** AEG-V16-024 / REQ-V16-FEC-08 / UI-V16-FEC-08 / T-V16-FEC-08

## Source / Assumption / Unknown / Decision Required

- **Source:** FieldShell, CommandBar, their component tests, and WBS Master.
- **Assumption:** shared-component checks provide a baseline; each screen still owns keyboard/focus and visual acceptance evidence.
- **Unknown:** full browser assistive-technology and visual-regression artifacts are not available in this workspace.
- **Decision Required:** do not call the gate complete until UX/QA attach those artifacts.

## Actual evidence

- `pnpm test -- --run src/shared/ui/components/tests/accessibility.contract.spec.ts`: 2/2 passed.
- `pnpm typecheck`: passed.
- The suite verifies required invalid fields expose label, error alert, and ARIA relationships, and busy commands expose state while blocking execution.
- Browser inspection on 2026-08-08 confirmed the skip link moves focus to `main`. It also found obsolete v2 contract copy in the UI catalog while the live adapter/footer identify contract 4.0; the display copy is corrected in this slice. The absent favicon is recorded as a non-accessibility local-server 404 and is not treated as a Gate pass/fail signal.
