OL-1953 — Supervisor refused a command
OL-1953 · ERR_SUPERVISION_CONTROL_FAILED
What happened
A start / stop / restart handed to the OS supervisor failed — the unit is registered but systemctl / launchctl / schtasks refused the control verb. Callers fall back to acting on the process directly, which is the pre-supervision behaviour, so this is a degraded path and not a hard failure.
What to do
Run openlatch system supervision status to check the supervisor.
