@mikem I'm not sure about ASSIGNED case - it seems to me that it also shouldn't log an error?

elif state == koji.TASK_STATES['OPEN'] and otherhost is None:
    log_error(f"Error: task {task_id} is opened but not locked by any host")
    return False

This probably needs to open with simply elif state == koji.TASK_STATES['OPEN']: and cover some different sanity rules for open tasks.

if the open task has no host, then that is an error that needs logging
if the open task has a different host, then that is a normal, non-error case (another host won the race) and we can simply return False.
if the open task has the same host, then that is probably worth logging. It either means there was a double open, or an admin trying to assign a task to a host that already has it.

I'm not sure about ASSIGNED case

It depends on the particulars. I think the case where the state is assigned but there is no host_id is unexpected and worth an error message.

For assigned in particular, the sanity checks might need to depend on newstate as well. I.e. it might be worth noting a double assign (same host id, state=newstate=assigned), but perfectly normal and expected for that host to open the assigned task.
