Remarks

The claim is filtered to the types the asking process has a handler for, which is what makes a rolling deployment safe: a job whose type an older replica does not know is left where it is for a newer one to take, because the absence of a handler is a fact about the deployment and not about the work.

The lease duration is the caller's because the bound belongs with the timeout the work runs under, and the two are ordered against each other — an attempt is cancelled before its lease can expire underneath it. Nothing here enforces that ordering; it is enforced where both values are configured.
