The rollup finishes in two seconds on the shared host, and its "in progress" and "ok" check-ins reached Sentry in either order; when "ok" landed first, the late start was never closed and the monitor reported a timeout ten minutes later. One check-in at the end cannot race, and a run that hangs still shows: nothing arrives and the night is marked missed.
