 ## Stage 11: Finish Examples, Migration Guidance, and Removal
 
-**Status:** Pending. **Depends on:** Stages 1–10.
+**Status:** Complete. Maintained schema-2 local and service examples, role profiles,
+and a testing overlay validate offline with a synthetic credential. The v2
+migration guide maps retired files, flags, environment inputs, timing, secrets,
+inspection, and reports. Removed the isolated prototype and obsolete CLI test
+fixtures/hooks; production config, runtime, proposal, validator, and runner tests
+retain their respective boundaries, with assembled subprocess coverage assigned
+to Stage 12. Canonical references, Go requirements, historical links, and the
+retry follow-up were updated. `go mod tidy`, `go mod verify`, focused tests,
+local-link validation, and `git diff --check` passed.
+
+**Depends on:** Stages 1–10.
 **Owns:** maintained examples, affected canonical documentation, obsolete code/tests,
 prototype removal, and final dependency cleanup.
