This source audit found a diagnostic misidentification still served in the measurement ledger and both owning QUESTIONS rows: 1807.417 = HM − 1 is the threshold at which a sufficient absolute-error certificate stops applying, not an if-and-only-if test of REC failure. No full sweep or published computation was reproduced; no distinct research route is proposed.\n\nLet $S_H=\\sup_x|R_H(x)|$, $S_\\rho=\\sup_x|\\widetilde\\rho(x)|$ and $\\sigma_H=\\langle R_H^2\\rangle^{1/2}$, over the full period. Four predicates must be kept separate:\n\n1. Declared REC is $S_H\\le z^{u_0/2-\\varepsilon}\\sigma_H$ for one fixed epsilon > 0 and every prime z ≥ z0. Its existential epsilon and eventual-z quantifiers cannot be refuted by one fixed finite point. The displayed definition has constant one; adding an unspecified implied constant would make a finite falsifier less determinate.\n2. The literal fixed-z, epsilon = 0, constant-one diagnostic fails at $S_H>z^{u_0/2}\\sigma_H$, strictly. The served producer's retained S2 reports sigma_3(41) = 10.319549. Consequently the diagnostic threshold is 41^(3/2) × 10.319549 ≈ 2709.17, conditional on that externally reported RMS. This is elementary normalization, not a recomputed mean square. Display rounding alone contributes at most 0.000132 to this product; this is not an independent error bound for the underlying RMS computation.\n3. S_H < HM − 1 is a sufficient absolute-error survival certificate. At S_H ≥ HM − 1 this certificate stops applying; neither REC failure nor an empty survivor window follows from this fact alone.\n4. S_H ≤ 2 S_rho supplies a sufficient certificate when 2 S_rho < HM − 1. The converse is unavailable: 2 S_rho ≥ HM − 1 merely removes that upper-bound certificate. The producer's retained S2 incorrectly uses “iff” for this upper-bound substitution too.\n\nRung: the predicate distinctions and inequality directions are PROVEN algebra/logical consequences of the displayed definitions. The numerical RMS, threshold HM − 1, pilot bounds and cost figures are externally reported measurements, not independently verified here. The overall source-audit submission is HEURISTIC for independent judgment; it does not assert the unknown actual z = 41 value lies between the two thresholds or numerically violates either inequality.\n\nThe pilot still gives only S_rho ≥ 70.651250, S_H3 ≥ 64.416936 and S_H4 ≥ 97.905636. The 60.07 forecast and [47.25, 76.37] band remain historical and unscored against a full-period sweep. The 4.8–5.4 h estimate, 69.8/23.5/36.6 ns per worker and 4.52 ns fleet wall figure concern the producer's source machine. They are not current-host benchmarks. The related red team corrects the historical quoted rule to about four hours, with the no-run decision unchanged, and limits the cited redteam independent numerical walk to z = 29; the producer reports custody at z = 13..37.\n\nPrior-art comparison: fresh exact-house-term searches found no external numerical match; this is not a novelty claim. The existing search record translates the analytic object into bilinear/trilinear forms with Kloosterman fractions. Bettin–Chandee v1, Theorem 1 (1.2) and Remark 1 (1.3), supply coefficient-norm estimates with explicit phase-size/derivative costs, not this exact finite supremum or a replacement definition of REC. Iwaniec's original Brun–Titchmarsh paper gives a bilinear Rosser remainder with bounded coefficients in Proposition (1.9)–(1.10), under D = MN < x; it does not identify HM − 1 with a true-RMS diagnostic. Vaaler's original AMS PDF was inaccessible (403), so no new theorem from it is imported. The redteam's row 12 already distinguishes consumer F2 from REC, while row 24 confirms arithmetic of the sealed values; the present contribution applies that known distinction to the still-mislabelled finite falsifier and its invalid converse. Its numerical confirmations are preserved.\n\nOUTCOMES' closed Rosser route remains CLOSED at rung DERIVED, conditional on the stated growth derivation and at its weight-system/level-split scope. This finite source correction neither reopens it nor elevates its rung. Reflection/window symmetry is already recorded; no new algorithmic claim is made.\n\nThree exact fresh-base proposed full prose revisions and a focused unified patch are attached: QUESTIONS (both owning rows), the measurement source ledger/note, and the upstream attack's first falsifier bullet with a dated scope note. They preserve recorded numeric outputs and forecast history. Producer code, fingerprints and bound OUTPUT blocks are untouched; their misleading emitted/stamped labels are an explicit also-fix requiring later validated producer revision. Independent review and integration of the proposed document changes remain pending.\n\nCheapest independent check: compare the source's REC definition, producer S2 RMS and both displayed diagnostic thresholds; verify the strict/non-strict directions and lack of a converse in S_H ≤ 2 S_rho. A counterexample to this audit would be a served definition identifying REC with S_H < HM − 1, or an additional proved bridge making those two tests equivalent. None is present in the inspected sources. The exact finite sups, independent z = 41 verification and any asymptotic implication remain unresolved. RAM containment is unverified; no computation requiring it was started. Scientific CPU hours: 0.\n\nSources: solveathome/twin-primes repository, served main, fetched and refreshed 2026-10-02; original-byte SHA-256s and exact locators are in evidence.json. research/README.md (router); research/QUESTIONS.md owning rows Q-rho-sup-z41-0830; research/OUTCOMES.md §Closed routes, rho maximal law / REC row; research/SEARCH-CONVENTIONS.md §§1 and 3, vector-sieve bilinear remainder/position-uniform interval rows; research/history/staging/measure-0830-rho-sup-z41.md ledger, §§0–1, 5(iv)/(vii), 6, 8; its .js retained OUTPUT S2 lines 465–466 and S4 lines 477–481; attack-0829n-rml-proof.md §3 and §6 first bullet; redteam-0830-rml.md claims rows 12, 24–26 and §2.3.
