AI agents that take real actions can fail in two ways: they crash halfway and repeat or lose the action, or they propose something dangerous and nothing stops them. In a factory, both are expensive.

GhostShift is a self-healing factory agent that fixes broken machines safely. The agent only proposes a fix. A separate governance layer checks it against policy, records the intent in a MongoDB ledger, and verifies the result by reading the machine's state back.

We demo three cases on a simulated factory:
1. Fix: a broken sync is repaired using a past procedure found with Atlas Vector Search.
2. Crash: we kill the worker mid-repair, and a new worker finishes without repeating the fix.
3. Unsafe action: a simulated shutdown request is denied by policy before anything is touched.

Our claim is effectively-once execution through idempotent operations, independent verification, and a single worker with a lease.
