 # Align Narratio With Standard Repository Policies
 
-Status: Accepted; implementation pending.
+Status: Implemented (2026-09-28); release pending.
+
+Implementation evidence: The [implementation plan](implementation.md) records
+completion and verification of each bounded unit. Seven adopted policies are
+credited at the pinned source revision; the local release checker, runbook,
+publication tests, CI references, and OSS notices now follow the selected
+workflow. The full race-enabled suite, vet, module/format/shell checks, and
+synthetic release assets passed. No source release or asynchronous asset
+delivery was initiated by this implementation work.
