Discovery is asymmetric across middleware
Restore bidirectional fleet discovery while retaining supported middleware diversity.
Pairs with DDS discovery and domains in Production ROS Operations. 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.
- Bidirectional participant discovery
- No traffic leaks to excluded interface
- Hidden regression behavior
- Root cause explanation
