This differs from agent worktrees (managed by the gateway for agent isolation). The orchestrator manages its own state worktree independently.

See `orchestrator/state_store.py` for implementation details.
**Startup reconciliation:**

On orchestrator restart, orphaned container state is automatically recovered. For each pipeline showing `status=RUNNING`, any agent/container whose container ID is absent from the live Docker container set is marked `FAILED`. If at least one stale entry is found, the pipeline itself is marked `FAILED` with an error message instructing operators to restart via `POST /pipelines/{id}/start`.

This prevents pipelines from being stuck in a `RUNNING` state indefinitely after a crash. Operators (or CI systems) can detect the `FAILED` status and restart the pipeline using the existing restart endpoint, which preserves worktrees and phase state while re-spawning containers.

See `orchestrator/state_store.py` and `orchestrator/startup_reconciliation.py` for implementation details.
