Create or update Channel metadata
Operation boundary
- Caller: Trusted backend only
- Scope: Channel metadata and membership are written to cluster storage; large is recomputed from the current member count after membership changes.
- Atomicity: Metadata update, old-member removal, chunked member insertion, and large refresh are separate stages, not one transaction.
- Recovery: After a timeout or 400/5xx, replay the desired business state and verify membership through the protected Manager query.
