 ### Added
 
+- **Role-aware feedback completeness** (`detect_role_completeness` in `analyze.py`, surfaced through
+  `check_missing_status`). "Does the function have *a* status?" was not enough — a dimmer with an on/off
+  status but no brightness status silently passed and inflated coverage/Matter scores. The new check
+  flags a brightness/position **command** (DPT 5.001) whose device has no matching value **status**
+  (`missing_value_status`), using a device-identity match so it does not borrow a sibling's status.
+  Closes the demo's own documented limitation — recall on the demo house is now 5/5. Raised by an
+  external expert review. `tests/test_role_completeness.py`.
+
 - **Project Policy Profile** (`policy.py`, new MCP tool `check_policy`). Validate a project
   against *its own* agreed rules (main-group taxonomy, naming regex, command/status exemptions)
   instead of one universal "professional standard" — a direct answer to integrator feedback that

-\* **Honest limitation surfaced by this very demo:** the missing-status check currently asks
-"does this control have *a* status?", not "does it have *each expected* status type?". The Kitchen
-dimmer has an on/off status, so it isn't flagged for its missing brightness status. Tracked for a
-future release.
+\* **Now fixed (role-aware feedback completeness).** This demo originally surfaced an honest
+limitation — the missing-status check asked "does this control have *a* status?", so the Kitchen
+dimmer's on/off status masked its missing brightness status. `detect_role_completeness` now flags a
+brightness/position **command** (5.001) that has no matching value **status** (`missing_value_status`),
+without borrowing a sibling device's status. Recall on this demo is now 5/5.
