## What changed
- Allow a valid Ready report to replace a deferred environment's provisioning failure while preserving the same environment instance.
- Treat provisioning failures as retryable and reconnect when a completed or concurrently publishing startup attempt contains a stale failure.
- Report provisioning failures from `status()` without starting a connection, and retain Ready state when a late failure arrives.
## Testing
- Cover recovery after failed and invalid provisioning reports, capability-root resolution after recovery, and the race between Ready and publication of an earlier startup failure.
