The controller refuses a safe bend

Restore progress while retaining higher cost for trajectories near shelving.

Pairs with Controllers and critics in Nav2 Incident Response. 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.

  • Safe bend completes
  • Near-wall trajectories remain costlier
  • Hidden regression behavior
  • Root cause explanation
