# AEG-V16-023 — Screen state matrix regression

**WBS / Requirement / UI / Test:** AEG-V16-023 / REQ-V16-FEC-07 / UI-V16-FEC-07 / T-V16-FEC-07

## Source / Assumption / Unknown / Decision Required

- **Source:** screen contract, T01–T10 catalogue, and its Vitest suite.
- **Assumption:** each template is exercised by its owning screen integration; this catalogue verifies the shared contract baseline.
- **Unknown:** visual/a11y evidence remains a separate AEG-V16-024 gate.
- **Decision Required:** no screen-specific state policy was invented; missing READY/FORBIDDEN were assigned to the established CRUD template.

## Evidence

- Mandatory states are typed as `StandardScreenState`.
- T01 now covers READY and FORBIDDEN; all 13 standard states are covered across T01–T10.
- `pnpm test -- --run src/shared/ui/screen-types/tests/catalogue.spec.ts`: 4/4 passed.
- `pnpm typecheck`: passed.
