+# Docs Guild Update — 2025-10-22
+
+**Subject:** Concelier Authority toggle rollout polish  
+**Audience:** Docs Guild, Concelier WebService Guild, Authority Core
+
+- Added a rollout phase table to `docs/10_CONCELIER_CLI_QUICKSTART.md`, clarifying how `authority.enabled` and `authority.allowAnonymousFallback` move from validation to enforced mode and highlighting the audit/metric signals to watch at each step.
+- Extended the Authority integration checklist in the same quickstart so operators tie CLI smoke tests to audit counters before flipping enforcement.
+- Refreshed `docs/ops/concelier-authority-audit-runbook.md` with the latest date stamp, prerequisites, and pre-check guidance that reference the quickstart timeline; keeps change-request templates aligned.
+
+Next steps:
+- Concelier WebService owners to link this update in the next deployment bulletin once FEEDWEB-DOCS-01-001 clears review.
+- Docs Guild to verify the Offline Kit doc bundle picks up the quickstart/runbook changes after the nightly build.
