ob_bitflag.py is the follow-on the word-level refutation named: for every 4-byte
offset in the window and every one of its 32 bits, count how many entities have
it set, keep the pairs whose count is exactly the counter, and require them to
match again after a transition. Both polarities, since an objective could be
marked by a bit that is CLEAR on it.
Three runs, no verification, and the reasons are recorded: run 1 gave 187 + 33
candidates at counter 4 and then reported "the counter never moved" for 700 s -
about a mission that had ENDED in GAME OVER partway through; run 2 hit the same
dead mission; run 3 had the counter at a different address (the guard refused,
correctly) and then froze after one filter.
The hole is closed. frozen() asks whether the guest is ANIMATING, and the GAME
OVER screen animates happily - mean colour (114,22,63) - so every liveness check
passed while the mission was over. frozen.in_flight() classifies the screen with
screen_id, and ob_hunt/ob_flag/ob_bitflag now abort with NO LONGER IN FLIGHT.
That is the second confident negative in this investigation that was really about
a dead world, so the rule is written down: before believing "X never happened",
show that the thing that would produce X was still running.

Three things from one Stage 02 run.
The address recurs a third time: HUD=4 RAM=4 at 0xbdb59668, so 3 of the 5 runs
measured put the counter exactly there.
The counter is NOT a live class head-count. With the counter at 4 the typed
entity list was 8 attackers, 7 friendly Delta Sabers, 7 turrets and the player -
no class has 4 members and no pair of them sums to 4. That sharpens the corpus's
existing "012 against 118 live ADAN" note from "not the hostile count" to "not
the count of any class this enumeration can see".
The flag experiment itself proves nothing, and why is the useful part. It found
20 offsets where exactly 4 of 23 entities agree, then reported "the counter never
moved" for 600 s. The guest had stopped advancing ten seconds into flight:
pilot.py logged 724 s of identical speed/yaw/pitch, and two screenshots six
seconds apart were byte-identical, max delta 0 over 863325 pixels - while
screen_id said "flight", the emulator burned 212% CPU and every liveness check
passed. So that was a fact about a dead world. Withdrawn along with it: the claim
in ob_session.sh that the counter climbs on its own in the first minutes, which
one advancing run supports and this one cannot.
frozen.py makes it a single call, checked in both directions (0 on the frozen
pair, 254 on two frames of a live run), and ob_hunt/ob_flag now say GUEST FROZEN
rather than waiting out their timeouts.
