Spine phase 4, byte for byte at 0x007dc871-0x007dc8c7. Three separate stores to
the same word -- clear, OR the self bit, then conditionally OR the alliance
mask -- which is what makes the alliance term an OR and is invisible in any
summary of the phase. The bit is the player's POSITION IN THE VECTOR.
Checked against the almem bytes the game archived: 72 of 80 player-records
agree, and the other 8 are predicted by the same model (FinalizeTurnRecords also
runs on load, and the load path does not run the spine, so every save's earliest
archived turn carries a zero mask -- true on all 11).
Reported as loudly: the corpus cannot separate `1 << vectorIndex` from
`1 << PlyrIdx` (0 of 80 records differ), cannot separate the OR from a plain
assignment (every observed alliance mask already contains its member's own bit),
and cannot separate the ALid guard from an AL != 0 guard. Those three are
instruction-stream readings only.
ModCount, named and enumerated. StrategyServer::Write tags both words itself, so
S+0x8 is the wire's ModCount and S+0xc is Frame -- addresses.json has the name
on the wrong word, and turn-driver.md's "they stay in lockstep" is corrected in
place. RTTI gives the reason for the two bases: Game::StrategySim is a base
sub-object at offset 4.
29 writer sites: 20 command handlers plus 6 inlined in the command-batch applier
(each an unconditional bump on ENTRY, before validation), the two turn drivers,
and the abandon/chaos check -- which is gated on Abdn, false on all 28 systems
of all 11 saves. So the per-turn delta is 2 + one per command applied out of
every player's TurnCommands block; the 0x1b4 container stride independently
confirms lane Q's block layout. It is not derivable from the pre-turn save.
The residual is a watchpoint, specified with its own written prediction (exactly
12 hits on turn1-state) and four falsifiers. Direct-call reachability is stated
as the lower bound it is, per lane V2's indirect-edge measurement.
