your company's "install scheduled" sub-stage, and any matching checklist steps are ticked off.
Only available while the job is in schedule.

The token's role must be allowed to work production, and unless it can act on every record, the
token's user must be the job's production manager. If the action isn't available, the response is
422 with success: false and an error message; if the role isn't allowed, it is 403.
