Changes - PluginWritableResource.requires_role: Optional[List[str]] — when set, the POST/PUT/DELETE handler returns 403 if current_user.role is not in the list. 'admin' role always passes (super-user override). Backwards compatible: resources without the field accept any authenticated user (legacy default). Validator enforces kebab-case role names (^[a-z][a-z0-9-]*$). - routes.plugins.writable_data: enforces requires_role at the endpoint, with a 403 message naming the required roles and the actor's current role. - routes.plugins.readonly_data: auto-injects :current_user_id and :current_user_role as bind params on every readonly query. Plugins can reference them directly in SQL for server-enforced scoping without an app-layer wrapper. The two parameter names are reserved — client requests carrying them in the query string get 400 (no identity spoofing). Tests - tests/backend/test_plugins_rbac_and_scoping.py — 13 cases covering Pydantic acceptance/rejection, 403/200 paths for writable, scoping/spoofing for readonly, backwards compat for resources without requires_role and queries without :current_user_id refs. Compat - Existing plugins (PM Essentials) continue to work unchanged — the new field defaults to None and the auto-injected bind params are silently ignored if the SQL doesn't reference them.
