worker has no Fleet task to restart

Error message

worker {worker_id} has no Fleet task to restart

What it means

Restart guard in Fleet restart_worker: neither the rebuilt ledger state nor the late-arrival lookup finds any task entry for the worker, so there is nothing to restart. The worker id names a worker with no Fleet task history in this run.

Solutions

1. Verify the worker_id against the run's task list (inspect_worker / run state) before restarting.
2. Start a new Fleet task for the worker if the old one was already cleaned up.

When it happens
