The Lifecycle
Transitions Explained
The transition rows describe stored state changes, their checks and their recorded effects. A queue receive, provider outcome and staff action can reach different lifecycle boundaries.
What Cannot Happen
Setup does not wait for DNS readiness; the verification refresh determines readiness. Only the purge sequence removes a setting, including a pending or failed setting.
Concurrency and Timing
Each workspace has one setting. Per-process sender caching delays selection changes by up to a minute. HQ sender reads refresh and write verification; no scheduled refresh is implemented.
