#120314, #120377, #120444 and #120450 are on main: their PROBES entries,
every expect_gap naming them and the gap_open(120444) audit branch go, so
those cells are plain tests again (two of those probes read source text,
which the suite must not do). Cell 5's README row no longer claims a
strict xfail.
The two static strict xfails with no probe and no fix PR
(STREAM_ACK_LOST_GAP, STREAM_CRASH_AFTER_ACCEPT_GAP) become run-time
xfails via _pending_fixes.known_failure: only the final assertions run
under it, after every wait (restart, catch-up, settle) has succeeded,
and only an AssertionError matching the gap's own signature XFAILs; any
other failure stays red and a fixed tree simply passes. The whole-run
audit now skips only tokens whose cell actually XFAILed this run.
