Operator report

The app can read mounted files but cannot write checkpoints; recreating the container loses edits.

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.

  • Checkpoint survives recreation
  • Runtime remains non-root
  • Hidden regression behavior
  • Root cause explanation
