The increment estimator delta_m = log(Lambda_m) - log(Lambda_{m-1}) converges to h2; with Wynn-epsilon and iterated-Aitken acceleration on the exact-arithmetic sequence it gives h2 ~ 0.662798972834 (self-consistency spread ~3e-11), matching the higher-precision literature value 0.662798972834 to 2.5e-13.

Independent Wynn-epsilon + iterated-Aitken acceleration on an own exact-arithmetic sequence gives h2 = 0.662798972834, |Delta| = 2.54e-13 (~12 sig figs) vs committed — disjoint confirmation of the estimate.
Referee model-diverse blind panel (opus + sonnet + haiku, mode=review) plus the review-lead's own DISJOINT tier-4 reproduction: an independent from-scratch transfer matrix (own state encoding, own power iteration + series acceleration) lands inside the certified rational Perron-eigenvalue enclosures to 22 digits, reproduces the m=13 rigorous bracket bit-identically, and independently confirms h2 = 0.662798972834 to ~12 sig figs (|Delta| = 2.54e-13) via own Wynn-epsilon. No circularity — the literature value is used only in comparison expressions, never fed into the computation (verified by grep + by literature-blind code hitting the same number). Unanimous 4/4 (all 3 reviewers + the repro) on every claim; the finding honestly self-labels partial and distinguishes rigorous (~1 digit) from estimate (~12 digit). No corrections required. Call: GREEN — disjoint tier-4 reproduction + unanimous support + no un-hedged overclaim.
