ResultFresh-block replication of the row-and-column n-tuple leaf at larger scale: wider tables trained until the validation margins plateau, screened beside the first candidate

Held-out screen, 512 never-read paired public-development games (0xa52f2380+): the frozen n-tuple tables as the leaf of the depth-3 seven-stratum fair search averaged 481,869 points and 139.39 moves against 326,717 points and 95.87 moves for the identical search with the frozen fair leaf: paired +155,153 points (bootstrap 95% lower bound +126,819, Student-t lower bound +126,919, upper bound +183,307, detection floor 28,185), W-T-L 333-0-179, halves +159,105 / +151,201, lower quartile 241,610 vs 192,040, moves +43.52. The preregistered gate PASSES. Replication: the first experiment's frozen tables (SHA-256 0ade9d4e4080ebdd52a1474b1a13410dc8dfb77f5eba24b078aa7703c92ace0b) as the same leaf on these fresh seeds averaged 487,066 points and 140.83 moves; prior-d3s7 minus fair-d3s7: paired +160,349 (bootstrap 95% lower bound +129,753, Student-t lower bound +129,626, upper bound +191,264, detection floor 30,670), W-T-L 330-0-182, halves +133,349 / +187,349. The replication criteria PASS. Scale: the wider, longer-trained candidate against the first candidate on the same seeds is -5,196 paired (bootstrap LB -40,535, t LB -40,060, UB +29,158, floor 34,803, W-T-L 267-1-244): the preregistered scale verdict is inconclusive. Against the program's standing reference, the fair leaf at depth 4 on the same seeds (397,154 points), the candidate is +84,716 paired (bootstrap LB +54,794, UB +114,355, W-T-L 298-0-214); diagnostic only. The first candidate against fair-d4s7 on these seeds: +89,912 (LB +58,243); diagnostic. The same tables played directly one ply averaged 328,039 points, +1,323 paired against fair-d3s7 (LB -17,545); diagnostic. Fair-d4s7 minus fair-d3s7 on these seeds: +70,437 (LB +46,917). Candidate: the tables of the main run's validation point at 2,000,153,332 training moves (layout rows,cols,win23,win32,win24,win42,phase=all, alpha 1, 5,800,000,000 entries), whose paired margin on the 256-game training-role validation block was +187,500; SHA-256 824b0a39a90d8a5aae63438c1538d4c5022f0e0f09c75fb7e2d758a1d6c6fb8a. Main run: 4,500,370,590 training moves, 47,477,538 games, 9 validation points, mean 1,184,973 moves per second, stopped by the plateau rule (last 4 validation points mean +165,666, the 4 before them +173,783). Training-signal check: at least one validation point of the main run had a positive paired margin.
