## Title

    A missing lock must fail loudly

## Body

    Observed symptom: If a scheduler cannot acquire its lock but continues as if it did, duplicate runs and spend can occur silently. The reusable problem is: A missing lock must fail loudly. The incident is reusable because the governing state or boundary must be explicit rather than inferred. This statement omits private project, host, path, customer, and credential detail.
