+# Task 6 report
+
+## RED baseline
+
+`pnpm audit:platform` initially exited with code 1. The audit reported missing API declarations, route entries, and view files for the resource contract catalogue.
+
+## Implementation
+
+- Added `src/api/resources.ts` as the single front-end catalogue for all 46 backend resource contracts, including path, title, mode, page kind, and fields.
+- Added route modules and declarative list/tree pages for each resource.
+- Added reusable read-only and tree pages; read-only definitions do not render create, edit, status, or archive controls.
+- Updated the shared CRUD page with server-side keyword filters, identity-based details, typed form data, archive confirmation, and API error messages.
+- Removed platform UI use of internal numeric identifiers in favour of `identity` and `parent_identity`.
+
+## Verification
+
+- `pnpm type:check` — pass
+- `pnpm audit:platform` — pass
+- `pnpm build` — pass
+
+## Notes
+
+The tree page consumes `parent_identity`; the corresponding menu API must expose that identity relation rather than an internal numeric parent key.
