-- The allocator learns the server's client-facing endpoint from the provider
-- allocation response, but nothing persisted it. Publishing the assignment
-- roster needs that endpoint, and a worker that crashed between allocating and
-- publishing had no way to recover it -- FindProviderAllocation would report
-- the allocation as already recorded while the endpoint was gone, leaving the
-- match permanently unable to reach ASSIGNMENT_READY.
