Wider than the steady-state window because a deployment gap is exactly the case the rescue exists
for: nothing was running, so nothing swept, and the graphs stranded by whatever took the process
down are older than a day by the time it returns. Runs once at Start(), so the cost of the wider
scan is paid once per process, not once per poll.
How far back the ONE startup sweep looks.
