# Code Generation Summary — Unit 4: Dashboard

**Status**: ✅ Complete
**Stories**: FR-05 (Dashboard with system availability widget)

## Files Created

| File | Purpose |
|---|---|
| `frontend/src/api/useAvailability.ts` | `useAvailabilityStatus` hook (TanStack Query, staleTime 30s) |
| `frontend/src/components/shared/AvailabilityStatusBadge.tsx` | Colored status badge with stale indicator |
| `frontend/src/mocks/availability/handlers.ts` | MSW handler for `GET /Availability/status` |
| `frontend/src/api/useAvailability.test.ts` | 4 hook tests (loading, success, error, refetch) |
| `frontend/src/components/shared/AvailabilityStatusBadge.test.tsx` | 8 badge tests (all statuses, message, stale indicator) |
| `aidlc-docs/features/cms-frontend/construction/unit-4/code/code-generation-summary.md` | This file |

## Files Modified

| File | Change |
|---|---|
| `frontend/package.json` | Added `@tanstack/react-query` 5.101.0 |
| `frontend/src/main.tsx` | Wrapped app with `QueryClientProvider` |
| `frontend/src/api/types.ts` | Added `AvailabilityStatus`, `AvailabilityResponse` |
| `frontend/src/pages/DashboardPage.tsx` | Replaced placeholder card with availability widget |
| `frontend/src/i18n/locales/en/translation.json` | Added `availability.*` keys |
| `frontend/src/i18n/locales/nl/translation.json` | Added `availability.*` keys |
| `frontend/src/mocks/index.ts` | Registered `availabilityHandlers` |
| `frontend/src/test/utils.tsx` | Added `QueryClientProvider` to `renderWithProviders` and `renderApp` |

## Test Results

- **Total tests**: 55 / 55 passed
- **Build**: ✅ clean (no TS errors)
- **Lint**: ✅ clean

## Key Decisions Made During Generation

- `test/utils.tsx` updated to include `QueryClientProvider` — required by the 3 existing integration tests that render `DashboardPage` (RouteGuard.test.tsx, LoginPage.test.tsx)
- `error` destructured field removed from `DashboardPage` (unused variable TS6133) — `isError` is sufficient
