A dashboard reopen landing inside the balance read's window joined the
in-flight route read but never registered its landing callback — the
read reported only to the open that started it, so the reopened
dashboard showed the stale remembered figure for its whole session
(issue #82, exactly as reported). The landing callbacks now collect in
a set and all fire when the read lands; the previous behavior was even
pinned by a test asserting the joiner stayed silent, which now asserts
the opposite. The store-level join test and a capsule-level
close-reopen repro pin the regression both ways.
