Sync the shared issue-core ingestion key from OpenBao into
actcore-runtime-secret via External Secrets, with an interim coulombcore
ClusterSecretStore bootstrap script and deploy docs. Removes manual key
injection from bootstrap-secrets.sh.
Close the intent-gap workplan by documenting the weekly-sbom-staleness
promotion path, adding a null-sink and live REST smoke script, and recording
rollback steps for Railiance. Update SCOPE and deployment docs to reflect
ISSUE_SINK_TYPE=rest and the remaining actcore-runtime-secret key patch.
Mount the-custodian memory/working from the railiance01 clone (hostPath)
so sweep writeback commits daily-triage notes; worker runs as uid 1000;
progress events store repo-relative working_memory_path; ops inventory
defaults use custodian:// URIs.
