train corrhist toward the draw score on an upcoming repetition

corrhist material damp, branch default

reduce less where deep searches overturn shallow verdicts

depth-instability relief, threshold 256 (rarer)

cycle draw-score recording at detection + in QS

corrhist material damp, moderate

corrhist material damp, aggressive

inverse: reduce MORE where depth demonstrably does not matter

depth-instability relief, threshold 64 (fires more)

qsearch-confirm deep RFP cuts (depth>=10)

depth-instability gate on NMP instead of LMR

qsearch-confirm RFP from depth 6 (larger population)

learn singular-extension outcomes, skip known-negative shapes

NMP root-depth relief, LTC non-regression

TM subtree ramp, LTC leg

vol gate + NMP from shallower depth (6.2 -> 5.2)

CONTROL: shallower NMP depth WITHOUT the volatility gate

root-depth relief on the NMP depth gate, STC

vol gate + NMP from 4.2 (curve point beyond 5.2)

coarse material-class correction source (6th)

single load for shared cont gravity; T=1 bit-identical

king-bucket-pair correction source (coarse, architecture-keyed)

vol gate + deeper NMP reduction (R 5.0 -> 5.6)
