After a restart the window started empty, so authors who had not sealed a
block since had no leaderboard row source, no author label series and no
timing caps until they authored again; on the dashboard that showed as
blank author cells for the smaller miners. The first poll now fills the
window (3600 blocks, 15 s against bob) from chain history, window only:
the authored counter is untouched so increase() sees no phantom burst, and
no tip timing is observed for blocks not watched arriving. Capped at 180 s
of wall clock.
The leaderboard's top-20 also drops rows with zero blocks in the range;
they were stale series with nothing to show.
