The spine's fourth phase, read byte-for-byte and implemented:
almem[i] = (1 << i) | (ALid != -1 ? AL : 0)
with i the player's POSITION IN THE PLAYER VECTOR, not its index field. Both
inputs are on the wire and so is the output, through the turn-record archive,
so the phase is checkable against bytes the original wrote:
app_turn_record: 11 saves, 80 player-records, 560 fields, 0 mismatches
(was 480 fields over six fields; almem is the seventh)
The eight zero masks of the corpus's earliest archived turn are PREDICTED, not
excluded: the archiving phase also runs on load, and the load path does not run
the spine. BuildTurnRecord takes spineRan and models it, so all 80 records are
compared.
Three parts of the rule the corpus cannot separate -- the bit index, the OR,
and the ALid guard -- are pinned in app_alliance with the separating inputs no
save provides, and app_turn_record prints that it could not separate them.
Divergence, closed and regressed reported separately:
turn1->turn2 default 209 -> 204 closed 5, regressed 0
turn1->turn2 --commit-blocked 209 -> 189 closed 29, regressed 9 (was 17)
turn2->turn3 default 108 -> 103 closed 5, regressed 0
turn2->turn3 --commit-blocked 108 -> 106 closed 13, regressed 11 (was 19)
T36 stays blocked: nine leaves would still be wrong (inc x3, sav x3 behind the
budget; three census leaves behind the design catalogue). It now closes all 24
turnstats leaves on the reference pair, so it becomes a clean +24 once those
two land.
Prediction and falsification committed first in 49ae628.
Gates run separately: clean-room OK; host ctest 43/43. No src/shim touched.
