docs: the bit-level OB flag is refuted - two transitions, no common survivor

The short-run strategy paid off: both counter steps happen in the first minutes
of flight, so one run yielded two complete passes before anything froze or was
killed. Pass 1 scanned at counter 4 and filtered on 4->8, leaving 29 of 710
candidates; pass 2 scanned at 8 and filtered on 8->12, leaving 2 of 197. The
intersection of the two survivor sets is EMPTY.

So no per-entity bit, in either polarity, anywhere in -0x400..+0xC00 around the
position triple, has a population that tracks REMAINING OB. With the word-level
refutation that closes the "objectives are marked in the entity object" family as
far as this method reaches.

Also recorded: 16 of pass 1's 29 survivors are the SAME word, pos+0x0250, with
sixteen different bits - the signature of a shared value rather than a flag, and
the same offset the word-level sweep found shared by 12 attackers. And a caveat
kept rather than smoothed: pass 2's B-sample HUD read 8 while RAM read 12.
