Not cancellable


`type`	`https://docs.frem.sh/reference/api/errors/not-cancellable`
HTTP status	`409` Conflict

What it means

The resource has moved past the point where it can be withdrawn: it was approved, is running, or has finished. Nothing was changed.

Example detail messages returned with this error:

This run is executing and can no longer be cancelled. Cancelling is possible only before approval.

Re-read the resource’s current state. A run that is already approved has to finish (or be handled by an operator); it cannot be withdrawn.

All fremforge API errors are RFC 9457 problem+json:

{
  "type": "https://docs.frem.sh/reference/api/errors/not-cancellable",
  "title": "Conflict",
  "status": 409,
  "detail": "..."
}

Branch on type, not on title or detail - those are human-readable and may be reworded.
