+## Owner-reported cutover outcome
+
+KeyCape reported on 2026-08-23 that its governed recovery path completed the
+four-class replacement, including privacyIDEA signing-secret replacement, and
+that all four deployments were Ready with positive and negative checks passing.
+No credential values or live Secret payloads were returned to NetKingdom.
+
+The remaining NetKingdom action is source reconciliation: Authelia 4.38 does
+not support `*_FILE` overrides for OIDC client list entries. The ConfigMap must
+therefore use the supported template filter reading the Secret-mounted bcrypt
+verifier, with `X_AUTHELIA_CONFIG_FILTERS=template` enabled in the Deployment.
