Record what shipped, and what is still only believed

STATUS was written before the deploy and still asked for a VACUUM that has
since been run. Replaces that with what was actually verified against the
running service, and with the two things a next session would otherwise have
to rediscover.

The post-vacuum sizes were never measured, so the projection stays a
projection; the query to settle it is in the file. And the scroll gap is
promoted from a footnote to the one real open item, because re-reading that
path after shipping found a bug in it -- which is the argument that reading it
again is not the fix.
