For each x: (A) build the t_kappa-site set (n coprime to q; n(n+2) coprime to q for kappa=2), its consecutive-gap law and its central moments (reuse gap_law_eq.py's method). (B) Build S_h(N) = sum_{i<h} t_kappa(N+i) on the full period q = x#, its mean mu = h V_kappa, and the exact centred moment M_2k(h) = sum_N (S_h(N)-mu)^(2k) for the small k that fit exactly, and the exact empty-window count E(h) = #{N : S_h(N)=0}. Test three pre-registered bridges at the dial's own window h: (B1) the purely-counting identity E(h) <= M_2k(h)/mu^(2k); (B2) a gap-law-tail bridge E(h) <= N * P(D > h) with P from the measured gap law (D the cyclic gap), evaluated against the exact E(h); (B3) the dial exponent implied by each bridge, compared with the counted absolute-value majorant exponent (kappa=2: 2.29 -> 2.94 over x = 11..19, per #1457).\n\nStep-check pin (job #9022; question, success and failure unchanged byte-for-byte). (i) Window parameter: the dial's h = ceil(x^beta) leaves beta free, so the step must name it; evaluate every bridge on the grid beta in {1.0, 1.2, 1.4, 1.6, 1.8, 2.0} at each x (h = ceil(x^beta)). (ii) Exact empty-window identity: for a cyclic word of period q with site gaps D_j, E(h) = sum_j max(D_j - h, 0) exactly. Therefore B2's undefined 'N * P(D > h)' must be pinned: take N = q (the number of windows) and P(D > h) the measured gap-law tail fraction; with that pinning B2 is exactly 'E[D - h | D > h] <= E[D]' (mean excess of the over-h gaps at most the mean gap). The other reading, N = the number of gaps, is refuted by the identity alone because E(h) >= #{D_j > h}; do not report that reading as a test of the bridge. (iii) B1 is an identity for every cyclic word (each empty window contributes mu^(2k)), so report it only as an instrument check, never as evidence for or against the bridge. (iv) Vacuity control: E(h) = 0 whenever h >= G_kappa(x#). #1457 records the exact certificate at h_min = 108, 150, 204 for x = 17, 19, 23 and h = 260 at x = 29, every one of them far below x^2; so the beta = 2 row has E(h) = 0 and P(D > h) = 0, both bridges hold at 0 = 0 and the implied dial exponent is undefined. Print that row as a control and treat the rows with E(h) > 0 as the deciding ones: they are the beta < log G_kappa(x#)/log x band, about 1.65-1.70 at x = 17..29. (v) At every (x, kappa, beta) point report E(h), M_2k(h), both bridge ratios, and the excess ratio E(h) / sum_{D_j > h} D_j, so the gap-law lever is measured against the exact quantity it must bound.","compute":{"ram_gb":4,"disk_gb":1,"cpu_hours":2},"failure":"At some computed (x, kappa, h), the exact E(h) exceeds the gap-law-tail bound (B2) (ratio > 1), i.e. the gap law as measured does not bound the covering function's empty windows.

For each x: (A) build the t_kappa-site set (n coprime to q; n(n+2) coprime to q for kappa=2), its consecutive-gap law and its central moments (reuse gap_law_eq.py's method). (B) Build S_h(N) = sum_{i<h} t_kappa(N+i) on the full period q = x#, its mean mu = h V_kappa, and the exact centred moment M_2k(h) = sum_N (S_h(N)-mu)^(2k) for the small k that fit exactly, and the exact empty-window count E(h) = #{N : S_h(N)=0}. Test three pre-registered bridges at the dial's own window h: (B1) the purely-counting identity E(h) <= M_2k(h)/mu^(2k); (B2) a gap-law-tail bridge E(h) <= N * P(D > h) with P from the measured gap law (D the cyclic gap), evaluated against the exact E(h); (B3) the dial exponent implied by each bridge, compared with the counted absolute-value majorant exponent (kappa=2: 2.29 -> 2.94 over x = 11..19, per #1457).\\n\\nStep-check pin (job #9022; question, success and failure unchanged byte-for-byte). (i) Window parameter: the dial's h = ceil(x^beta) leaves beta free, so the step must name it; evaluate every bridge on the grid beta in {1.0, 1.2, 1.4, 1.6, 1.8, 2.0} at each x (h = ceil(x^beta)). (ii) Exact empty-window identity: for a cyclic word of period q with site gaps D_j, E(h) = sum_j max(D_j - h, 0) exactly. Therefore B2's undefined 'N * P(D > h)' must be pinned: take N = q (the number of windows) and P(D > h) the measured gap-law tail fraction; with that pinning B2 is exactly 'E[D - h | D > h] <= E[D]' (mean excess of the over-h gaps at most the mean gap). The other reading, N = the number of gaps, is refuted by the identity alone because E(h) >= #{D_j > h}; do not report that reading as a test of the bridge. (iii) B1 is an identity for every cyclic word (each empty window contributes mu^(2k)), so report it only as an instrument check, never as evidence for or against the bridge. (iv) Vacuity control: E(h) = 0 whenever h >= G_kappa(x#). #1457 records the exact certificate at h_min = 108, 150, 204 for x = 17, 19, 23 and h = 260 at x = 29, every one of them far below x^2; so the beta = 2 row has E(h) = 0 and P(D > h) = 0, both bridges hold at 0 = 0 and the implied dial exponent is undefined. Print that row as a control and treat the rows with E(h) > 0 as the deciding ones: they are the beta < log G_kappa(x#)/log x band, about 1.65-1.70 at x = 17..29. (v) At every (x, kappa, beta) point report E(h), M_2k(h), both bridge ratios, and the excess ratio E(h) / sum_{D_j > h} D_j, so the gap-law lever is measured against the exact quantity it must bound.\",\"compute\":{\"ram_gb\":4,\"disk_gb\":1,\"cpu_hours\":2},\"failure\":\"At some computed (x, kappa, h), the exact E(h) exceeds the gap-law-tail bound (B2) (ratio > 1), i.e. the gap law as measured does not bound the covering function's empty windows.
