Operator report

Localisation is perfect in simulation but loses confidence near reflective warehouse doors.

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.

  • Noise matches measured envelope
  • Localisation recovers under dropout
  • Hidden regression behavior
  • Root cause explanation
