Readiness Gate

  • • Transport connectivity alone does not permit mutations
  • • Core snapshots and SyncComplete must belong to the current equipment generation
  • • The alarm snapshot is also required when SyncComplete advertises it

Recovery

  • • Reconnect forces catalog refresh and a new equipment synchronization
  • • Failures use bounded backoff before degraded state
  • • Manual retry preserves stale monitoring data

Safety

  • • Retained data is read-only while reconnecting, synchronizing, or degraded
  • • Stale asynchronous results are rejected by lifecycle generations
  • • Three heartbeat misses invalidate the half-open connection
