One server never follows startup
Restore deterministic startup while preserving managed shutdown.

How this lab works
You diagnose it — no command list.
Open the repair workspace and gather your own evidence in a real terminal. No diagnostic commands are handed to you — finding the fault is the exercise. Stuck? Progressive hints unlock inside the workspace.
Verification
Your repair must pass more than the visible symptom.
- All required servers active
- Managed shutdown succeeds
- Hidden regression behavior
- Root cause explanation
