The bag replay cannot reproduce the fault
Reproduce a transform failure from a recorded incident without modifying message stamps.
Pairs with Bags, logs, and reconstruction in ROS 2 Systems Debugging. Read the concept first, then diagnose it here.

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.
- Replay clock advances
- Transform error reproduces deterministically
- Hidden regression behavior
- Root cause explanation
