Retry an exhausted delivery from Rhythm HQ
What It Does
An authorized HQ operator retries an exhausted channel delivery.
The Flow
When Something Fails
The hop rows identify each retry boundary, any state left behind and the available observer. Only one failed-to-queued exhaustion update succeeds; another retry is refused. The retry claim coordinates operators, then ordinary send claims coordinate consumers.
Open Design Questions
The module findings retain unresolved cross-service authority and recovery questions where this flow depends on shared infrastructure.
