ALL-1873 PR-4: DRC UI — Run Data Audit button + source-type label

## ALL-1873 PR-4: DRC UI entrypoint **Linear issue:** ALL-1873 — Feature: Data audit entrypoint for Data Review Center **Branch:** wilbo/all-1873-drc-ui-entrypoint **Depends on:** PR-3 (triggerDataAudit mutation must exist in the schema for the frontend to call) ### What to do #### 1. Add useTriggerDataAudit hook in apps/dashboard/lib/staging/client.ts (or hooks/useDataReview.ts) Look at how existing mutations are wired (e.g. useReviewActions in hooks/useDataReview.ts or lib/staging/client.ts). Add a hook: function useTriggerDataAudit(): { trigger: () => Promise<void>; loading: boolean } Internally calls the triggerDataAudit GraphQL mutation with the current workspace ID from useWorkspace(). #### 2. Add the "Run Data Audit" button to DataReviewPage.tsx File: apps/dashboard/components/pages/DataReviewPage.tsx - Add the button near the page header / batch selector controls (study the layout of the existing SourceTypeFilter + BatchSelector controls around lines 100-200). - On click: call trigger() from useTriggerDataAudit(). Show a loading spinner while in flight. - On success: show a useNotice toast (useNotice is already imported from @texturehq/edges): "Data audit started — results will appear in the queue when ready" - On error: show a useNotice error toast with the error message. - The button copy: "Run Data Audit" #### 3. Regenerate GraphQL types After the backend schema change lands (PR-3), regenerate the @generated types: cd apps/dashboard && pnpm run codegen or the equivalent command in the dashboard package. Commit the regenerated files. #### 4. Add DATA_AUDIT to the frontend source type filter (if not already done in PR-1) If PR-1 already added DATA_AUDIT to SOURCE_TYPE_OPTIONS in DataReviewPage.tsx, verify it's present. If not, add it: { value: "DATA_AUDIT", label: "Data audit" } #### 5. Light test coverage Add a test to DataReviewPage.test.tsx (or a new DataReviewPage.audit.test.tsx) that: - Renders the "Run Data Audit" button - Mocks useTriggerDataAudit - Asserts clicking the button calls trigger() - Asserts the success notice fires ### Acceptance test - "Run Data Audit" button renders on the DRC page - Clicking it fires the triggerDataAudit mutation - Success state shows a toast - Error state shows an error toast - TypeScript compiles, all tests pass - CI green ### Key files - apps/dashboard/components/pages/DataReviewPage.tsx — main page - apps/dashboard/components/pages/DataReviewPage/ — sub-components - apps/dashboard/hooks/useDataReview.ts — existing review hooks (pattern match here) - apps/dashboard/lib/staging/client.ts — existing staging client (may also be a good place for the hook) - apps/dashboard/lib/@generated/ — generated GraphQL types (regenerate after PR-3 merges) ### Gotchas - This PR should NOT merge until PR-3 is merged and the triggerDataAudit mutation is deployed to the backend. Use a feature flag if you need to ship the UI before the backend is ready. - useWorkspace() from @/providers/WorkspaceProvider provides currentWorkspace.id — use that as workspaceId. - The DATA_AUDIT source type label in SOURCE_TYPE_OPTIONS (PR-1) ensures audit batches show up correctly in the batch filter dropdown after the audit runs. ### Out of scope - Any custom resolution UI for audit-specific anomaly types (Phase 3) - Scheduled audit controls (Phase 2) - Audit history / audit-specific tab (Phase 2)
