60 s labelled a slow-but-clean large rebuild degraded. The deadline moves to a
shared Commons DeployTimings constant that ConfigPublishCoordinator reads, and
the node's timeout is deadline - 15 s margin, so the held ack still lands in
time. A timed-out ack's reason now says the outcome was not reported in time,
distinct from a real sink failure.
