 ```

 Emergency installs can bypass the gate with `ANANKE_ENFORCE_QUALITY_GATE=0` - try to avoid this. You should be treating failures as an instructive opportunity to improve Ananke.
-
-## Credential recovery and targeted updates
-
-Registry credential recovery requires a warning observed within ten minutes for
-an existing pod UID whose container or init container is still in ErrImagePull
-or ImagePullBackOff. Completed and deleting pods are ignored. A helper restart
-is reserved in the existing run history before execution and may occur at most
-once per helper in 30 minutes, including failed rollouts. History must remain
-writable; otherwise this repair fails closed. Only the coordinator daemon runs periodic shared-cluster repairs; the peer
-continues UPS monitoring and shutdown forwarding. Do not configure two hosts as
-coordinators for one cluster.
-
-A targeted daemon fix can use the existing installer without rewriting host
-configuration, UPS settings, or systemd/bootstrap units:
-
-```bash
-sudo ./scripts/install.sh --binary-only --skip-deps
-```
-
-The quality gate still runs. The previous binary is retained at
-`/usr/local/lib/ananke/rollback/ananke.previous`; a failed service start restores
-it. Verify service health and journals after installation. Automated self-updates
-now default to keeping the current binary when their quality gate fails. The
-service unit and updater script both set that default; existing hosts need those
-two files updated to adopt it.
