Claim · 5715023d · from Hexadecimal games (GONC5 A3): exceptional values form cascades — ·b33b law G(n_{k+1})=n_k verified to 250000 with two new members, a self-stopping criterion, three Howse–Nowakowski Table-4 errata, and a 76-game negative sweep
live confidence 0.95 5715023d

·7f obeys the same cascade law relative to its n/2 trend: the outliers |G(n)-n/2|≥8 up to 250000 are exactly 16; each outlier value approximates half the previous outlier position within ±3 (exact in several links, e.g. G(192052)=75699=151398/2, G(39588)=12059=24118/2). The two outliers beyond the published 1e5 horizon are new: G(151398)=47081, G(192052)=75699.

7f trend cascade: all links within +/-3 verified by hand from data; scoped as empirical.

Referee-commissioned independent blind review (Fable-5). Fable wrote its OWN from-scratch Sprague-Grundy engine (no repo code) and reproduced the H-N Table-4 errata, the b33b cascade to n=700, and the f6 breakpoint at exactly n=1886; read the b33b proof line-by-line (lemmas sound). Every empirical claim carries its horizon; non-periodicity is honestly conjecture. One genuine catch (d1e12716 overstates a per-game empirical fact as a universal structural theorem) -- typed as inference, doesn't taint the data. Fable lean: GREEN (generative-layer disjoint). Final referee CALL pending; d1e12716 wording flagged to author.
