Held-out screen, 512 never-read paired public-development games (0xa52f2580+), four arms on identical seeds, no training. The frozen tables (SHA-256 0ade9d4e4080ebdd52a1474b1a13410dc8dfb77f5eba24b078aa7703c92ace0b) as the leaf of the depth-4 seven-stratum fair search averaged 516,155 points and 148.75 moves against 465,675 points and 134.82 moves for the same tables as the depth-3 leaf: paired +50,479 points (bootstrap 95% lower bound +14,707, Student-t lower bound +14,086, upper bound +86,224, detection floor 36,331), W-T-L 284-0-228, halves +67,335 / +33,623, lower quartile 233,182 vs 212,969, moves +13.93. The preregistered gate PASSES. The fair leaf's own fourth ply on these seeds: fair-d4s7 382,567 against fair-d3s7 332,968, fair-d4s7 minus fair-d3s7: paired +49,599 (bootstrap 95% lower bound +25,751, Student-t lower bound +25,578, upper bound +73,244, detection floor 23,979), W-T-L 289-0-223, halves +45,189 / +54,009. Depth-step interaction, per game (tables d4 minus tables d3) minus (fair d4 minus fair d3): +881 (bootstrap LB -40,932, t LB -41,742, UB +42,867, floor 42,550, W-T-L 250-0-262): the preregistered verdict is 'inconclusive'. Persistence: prior-d4s7 minus fair-d4s7: paired +133,588 (bootstrap 95% lower bound +102,051, Student-t lower bound +101,161, upper bound +165,801, detection floor 32,371), W-T-L 314-0-198, halves +137,477 / +129,699. The persistence criteria PASS. The tables' depth-3 margin on these seeds: prior-d3s7 minus fair-d3s7: paired +132,707 (bootstrap 95% lower bound +102,193, Student-t lower bound +101,741, upper bound +163,903, detection floor 30,913), W-T-L 309-0-203, halves +115,331 / +150,084. prior-d4s7 minus fair-d3s7: +183,187 (LB +150,976). Logical work per game: prior-d4s7 795,922,316, prior-d3s7 22,193,672, fair-d4s7 558,924,581, fair-d3s7 15,568,331; mean wall seconds per game on the shared 32-thread workstation: 152.3, 4.1, 175.7, 4.5. Theory falsifiers: primary upper bound below zero False; second leg upper bound below zero False; persistence lower bound at or below zero False.

What it had to pass
  • All CHECK gates passed on the frozen tables before the leased seed was read (including leaf-in-d4-search-determinism) — observed: 19 gate lines
  • screen artifact: illegalDecisions 0 and incompleteDecisions 0 in every arm — observed: null
  • bootstrap 95% lower bound of prior-d4s7 minus prior-d3s7 > 0 — observed: 14706.909765625

  • prior-d4s7 Q25 >= prior-d3s7 Q25 — observed: [233181.75, 212968.75]
  • Every table arm is the exact frozen best-weights.bin of RUN-20260905T193006Z-4fbeb4e5 (SHA-256 verified before the screen lease opened) — observed: 0ade9d4e4080ebdd52a1474b1a13410dc8dfb77f5eba24b078aa7703c92ace0b
  • Persistence (beside the gate): bootstrap 95% lower bound of prior-d4s7 minus fair-d4s7 > 0 — observed: 102050.977734375

Limitations
  • Public-development SCREEN tier, 512 paired games opened once; nothing here is a qualification claim, and protected and final cohorts stay sealed.
  • No table was trained or changed: both table arms are the first experiment's frozen candidate, selected there at the best of twenty training-role validation points; this screen inherits that selection but adds none of its own.
  • The depth-4 search is the standing reference configuration (1M-entry table, seven strata, terminal utility -1,000,000); a different terminal utility, table size or stratum count is a different configuration and is not tested here.
  • The fair-d3s7 and fair-d4s7 arms are context for the interaction reading; the preregistered comparator is the identical tables at depth 3.
  • Wall times were measured on a shared workstation with all four arms run in sequence at 32 threads; logical work and the ratios between arms on the same seeds are the trustworthy cost quantities.
  • The per-game artifact is cited by its public archive reference (data.drop7.dev, immutable run-scoped key, digest in the fragment); a byte-identical copy remains under runs/RUN-20260906T081306Z-e62d9837/ntuple-scale/screen/heldout.json on the workstation and a promoted copy under artifacts/results/.

Recorded against The frozen n-tuple tables as the leaf of the depth-4 fair search: a two-by-two leaf-by-depth screen on a fresh block.
