 ## Rules and gotchas
 - **Role checks must use ladder comparisons, never equality.** Roles rank viewer → editor → admin → superadmin. Use the minimum-rank helpers from `src/lib/roles.ts` (`canWrite`, `canDelete`, `isSuper`, `atLeast`). Where a local variable shadows the name, import with an alias, e.g. `canWrite as roleCanWrite`. `role === "admin"` silently excludes higher roles and has caused repeated bugs.
 - **Imports need explicit extensions** (`.ts`, `.tsx`, `.js`) everywhere.
 - **Vite resolves `.js` before `.ts`**, so a `.js` and `.ts` file with the same base name will import the wrong one. Give new hooks distinct names.
-- **Don't use `fallback: EMPTY` in api.js hooks.** It silently returns empty arrays and hides server errors; let the error state surface.

 ## Admin CRUD engine
-Descriptor-driven: `server/admin-crud.js` and `admin-schema.js` (server) and `adminSchema.js` (client) generate SQL and form fields from declarative entity configs. Adding an entity should mean adding a descriptor, not new CRUD code.

 - Child collections are deleted and reinserted wholesale. Unsafe for entities referenced by foreign keys elsewhere.
 - `reindex: false` prevents cross-entity sort order collisions.
 - The `OMIT` sentinel distinguishes unsent fields from deliberate clears.
