# Auditing

`mix continuum.audit` is a read-only operator task for workflow metadata and
patch-marker hygiene.

For live operational state, queue/lease lag, partition coverage, and fenced
repair actions, use `mix continuum.health`; see `guides/operations.md`.

```bash
mix continuum.audit --repo MyApp.Repo
mix continuum.audit --repo MyApp.Repo --format json
mix continuum.audit --repo MyApp.Repo --strict
```

The task reports loaded workflow versions, durable workflow-registration health,
their `Continuum.patched?/1` call sites, and whether each patch is still needed
by non-terminal runs. Registration health includes the supervised registrar's
state and any loaded hashes missing from `continuum_workflow_versions`. It also
counts `expired_leased_activity_tasks` — tasks still `leased` past their lease
expiry. A persistently non-zero count means workers are dying between claim and
completion faster than the steady-state sweep rescues them.

Patch verdicts:

* `still-in-use` means at least one non-terminal run of that workflow version has
  not journaled the patch decision yet.
* `safe-to-remove` means no non-terminal run is still before that patch site.

`--strict` exits non-zero when a patch is safe to remove, a loaded workflow hash
is not durably registered, or any run is stuck with
`state = 'stuck_unknown_version'`, making the task suitable for CI hygiene.
