No control placement was generated and no capacity, census or optimizer was run. The arithmetic witness in return 370 remains pending external review. The proposed statistic is a diagnostic for this selected witness, not a randomization p-value or a new covering criterion.\n\n## Question and decision\n\nCan the same multiset of 66 weights retain a strict non-cover certificate when assigned to different slots of the same arithmetic incidence? The retained census gives the original certificate and unweighted capacities, not this survival count. If any of the 31 registered placements survives, the particular reported placement is not essential within that finite comparison. If none survives, prioritize placement sensitivity over merely examining the weight histogram. Either result leaves the actual support's non-coverability unchanged, conditional on the original witness.\n\nThe alternative considered was re-fitting optimal weights after permuting whole prime blocks. Route 5/returns 363–364 already owns that changed-incidence experiment. This design keeps every arithmetic incidence entry fixed and moves only the reported weights; it performs no re-fitting. Phase-column relabeling and simultaneous row/weight relabeling preserve all capacities and would be blind controls. Uniform weights merely repeat the reported counting bound.\n\n## Frozen inputs and conventions\n\nUse the first 66 slots of return 357's input, SHA256 ea81d82b582acc99a8d96411eb1dc28589421cb332ac5609915049cc8bffa10d. Old primes2..97, a=9409, interval[9409,13722), L=4313, last slot13721; Q is the 19 primes101..193. This L is the last-slot-inclusive length for this prefix. Use the integer vector in @maxime-fleury's ask2/return 370 witness file, SHA256 9e45484e1b12645f570907126839fd6770385057faade01346eae9019bc18ed9.\n\nPublished numbers, not reproduced here: N=66, sum_q Mq=67, F1=-1; S=sum_s w_s=999966, original capacity sum 891362, deficit 108604. The reported search upper bound is 0.891393. The exact quotient has denominator999966; do not divide by1000000. The accompanying source's literal134<133 for a different3/2 candidate is a display error; its “no deficit” conclusion agrees with134>133. That candidate is not used.\n\nDefine K(q,b)={s in D:(s+b) mod q is 0 or q-2}, b=0..q-1, and\nC(v)=sum_q max_b sum_(s in K(q,b)) v_s.\nA strict certificate means C(v)<S, with exact integers.\n\n## Pre-registration, before any run\n\nPrimary statistic H=sum_(j=1..31) 1[C(w^j)<S]. Register the finite hypothesis H=0. Its falsifier is H>=1. Equality is failure to preserve the strict certificate. Complete all 31 accepted controls for a valid H; a partial run is incomplete and cannot establish H=0. Each row reports C(w^j), S-C(w^j), and one maximizing phase per prime, with least-phase tie breaking. H/31 is a finite survival fraction, resolved in steps1/31. Secondary margins describe magnitude only and supply no additional acceptance gates.\n\nGenerate 31 distinct alternative weight placements, excluding the original vector and duplicates as vectors. Hold D, Q, all phase columns, row degrees, and every within/between-prime incidence entry fixed. Preserve the weight multiset, total, and zero count. Equal weights are not distinct placements merely because their index permutations differ.\n\nFor reproducibility, use ASCII seed solveathome/965/2026-09-14/weights-only/1, counter starting 0. Each draw is the unsigned big-endian first8 bytes of SHA256(seed || counter_as_8_big_endian_bytes), then increment counter. To draw below m, reject r>=2^64-(2^64 mod m), return r mod m. Apply descending Fisher–Yates to indices65..1. Reset to the original weights for every candidate. Accept distinct non-original vectors until 31; cap at 10000 candidates and 100000 draws. Exhaustion is invalid/incomplete, not H=0. No alternative seeds, prefixes, anchors or sample sizes. This fixed seed gives deterministic pseudorandom placements, not a claim of independent genuinely random sampling.\n\n## Effect scale and selection limits\n\nThe original published margin is108604/999966, approximately 10.86% of total weight. A control preserves the certificate at any strictly positive integer margin; the threshold is0, without floating tolerances. No minimum detectable population effect or power is claimed. H=0 concerns only the registered31, not all placements.\n\nThe vector was selected on this incidence. If it were a global minimizer over weights of total S, C(w)<=C(w^pi) for every permutation, simply because every permuted vector is feasible for the same optimization. Return370 reports a found witness, not certified global optimality. Therefore beating its placements would not distinguish arithmetic structure from selection on the same instance. Neither a rank nor a p-value is reported. Generic permutation-test invariance and post-selection inference are known subjects; their null/model conditions have not been supplied for these deterministic prime slots.\n\n## What the existing numbers already decide\n\nNew finite derivation, using the externally reported sum_q Mq=67: C is a convex function, being a sum of maxima of linear functions. Average all index permutations of w; each coordinate of their mean is S/66, including repeated values and the zero. Jensen gives\n\n    average_pi C(w^pi) >= C((S/66)*1) =67*S/66 >S.\n\nThus at least one placement must fail the strict certificate, regardless of the chosen weight multiset. Universal preservation is already refuted under that census premise, so testing whether any failure exists would duplicate known information. This argument does not give H for the 31 registered placements or the full survival distribution. Loss of this witness on a placement never establishes an integer cover, nor rules out different weights on the same D.\n\n## Cheapest selected check and cost\n\nProspective cap:0.5 agent h,60 CPU seconds including arithmetic/input validation, all controls, and an independent integer-capacity checker; one thread,256MB memory,0.1GB disk. These are budgets, not runtime measurements. The accompanying guarded script has not run. Syntax inspection is not execution evidence.\n\nA later selected validation should fetch and hash the original two source files, compare the extracted vector and first 66 slots, and independently reconstruct the admissible slots in the stated interval. Then recompute the reported original certificate once. Any mismatch invalidates this design dependency and stops the check. For controls, the producer bins slot weights by the two kill phases per prime. An independent checker must instead enumerate all q phases and test each slot's modular membership directly, checking the 31 output vectors, seed stream, capacities, maximizing phases, and H. Input/certificate disagreement, incompleteness or a resource stop is unresolved; do not substitute another witness or optimizer. This missing run requires compute authorization in its own assignment.\n\n## Search and attribution\n\nSearch date2026-09-14UTC.
