Update: Annotate _access with inputType for the authoring UI

 Other modules extend `_access` with their own keys (e.g. `_access.users`, `_access.groups`) and tap both hooks with additional grants, all OR-combined with the base `public` grant. Use `addAccessClause` (exported from `adapt-authoring-api`) for the query-level grant so observers compose safely with each other and with any user-driven `$or`.
 
+`_access` carries an `_adapt.inputType: 'Access'` editor annotation so the authoring UI renders it as a single access widget rather than a raw object. A module adding a grant key should annotate its own sub-property too (e.g. an identity grant uses `_adapt.inputType: 'Principal'` with `options.apiRoot`/`labelField`/`kind`) so the widget can render it without any UI change.
+
 `_access.public` defaults to `true` — resources are public unless a grant or the creating UI sets it otherwise. This preserves open access for resource types without a sharing UI; clients that scope access (e.g. the course wizard) set the value explicitly.
 
 Enforcement is request-scoped: both hooks read `req.auth`/`req.apiData.query`, so `_access` is only applied to REST API requests. Internal/programmatic data access (e.g. server-side `find()`, preview, publish, export) bypasses it by design — there is no request identity to check against outside a REST request.
