+## Record Retirement Checklist
+
+Completion review confirmed that every accepted finding has one completed
+remediation, while the four rejected findings remain consolidated into their
+recorded owners. The retired remediation roadmap had one allocation for each
+of the 74 confirmed findings, with no duplicate or unassigned IDs. Its
+completed changes, including retirement of the completed comparison roadmaps,
+are present in repository history.
+
+The durable current-state owners already retain the implemented contracts and
+rationale: the [architecture policy](../policy/architecture.md) and accepted
+[stateless-execution ADR](../adr/0001-stateless-execution.md) own system
+boundaries; the CLI, configuration, operations, and integration documents own
+their public contracts; focused internal documents own implementation flows;
+and the testing policy owns test-maintenance guidance. No additional canonical
+document needs an audit-specific summary.
+
+When retiring these temporary records:
+
+1. Keep `docs/roadmap/future.md` as the only remaining roadmap and leave the
+   development guide's general roadmap routing in place.
+2. Remove this audit plan and the audit ledger. The remediation roadmap has
+   already been retired.
+3. Do not alter ADRs, release notes, executable code, tests, dependencies,
+   schemas, or current-state contract documentation as part of record removal.
+4. Confirm no remaining Markdown link targets either audit record; links
+   between the two records disappear with them.
+5. Re-run repository link, fence, and secret-pattern checks; the full default
+   and race-enabled test suites; both CLI help commands; `go vet`; and
+   `git diff --check`.
