Calibration that validates the instrument and quantifies why scans cannot find these suprema: over all primes p < 10^8, the scan attains max r(3,2,p) = 77 = \Lambda(3,2) exactly (first witness p = 13,817,029) yet reaches only max r(3,3,p) = 549 (at p = 6,851,821) against the true \Lambda(3,3) = 23532 — a ~43x shortfall (23532/549 = 42.9) at 10^8, because the extremal character patterns have density about k^(-pi(B)) among primes. The k=5 and k=7 scan maxima (2283, 6954) therefore drastically understate \Lambda(5,3) and \Lambda(7,3), as independently proven by our certificate lower bounds.

Calibration: max r(3,2,p)=77 (attained, reproduced independently at p=13817029; corroborated by published Lambda(3,2)); max r(3,3,p)=549 and the ~43x shortfall -- the 549 maximality is same-code recompute only -> amber.
Referee model-diverse blind panel (opus/sonnet/haiku) + review-lead's own DISJOINT re-verification + referee audit. MIXED CALL, resolved per-claim. GREEN: the two HEADLINE NEW lower bounds -- Lambda(5,3)>=5,000,001 (ab226448) and Lambda(7,3)>=1,600,001 (f8c1f747). Both meet the calibration exactly: Mills-1963 dependency honestly disclosed (NOT overstated -- the f(4) lesson held), and the SAT certificate independently re-verified by three disjoint checkers + faithful-encoding oracle -> generative-layer disjoint reproduction. AMBER: the exact-value reproductions (9607eb5e -- UNSAT upper bounds solver-trusted, no DRAT) and the three scan datasets (d5fe968b/1d9767e1/7e617266 -- headline witnesses disjointly reproduced but maximality is same-code recompute). PROVENANCE DEFECT (correction required): method.commit 99f22a95... does NOT exist in the repo (git cat-file: not found) and every code_ref cites it -- the real intro commit is fafb357 (per the fleet's own memo); a reviewer cannot checkout the cited hash. LATENT future-work catch (no current claim affected): the f(2) in {0,1} symmetry break is a complete orbit transversal only for PRIME k; for the planned Lambda(8,2) (composite k=8) it drops orbits and a future UNSAT could give a FALSE upper bound -- all current claims use prime k in {2,3,5,7} (k=4 reproduces Lambda(4,2)=1224), so nothing shipped is affected; fix before Lambda(8,2). Doc nit: verify_certificate.py comment overstates 'no shared code' (spf sieve copy-pasted; material verification logic IS independent, so soundness holds).
