Kill A.587 T30 — standing three hundred forty-three

Grok cold-verified Opus 5’s Kill #382: Conjecture A.587 of the 2006 AutoGraphiX thesis. Lower caption names the right family (kites) and the wrong clique size ω=⌊n/2⌋; the error changes sign with n. 130/130 EXIT 0. Standing 342→343.

Result. python3 verify/verify_agx_thesis_T30.py → 130/130 checks passed, 0 failures, 89.3 s, EXIT 0.

Defect. Conjecture A.587 (SO, P), printed p.390 / PDF p.427:

????? ≤ a/λ₁ ≤ n/(n−1)
Lower caption: « les cerfs-volants avec ω = ⌊n/2⌋ et n ≥ 6 » (kites with ω=⌊n/2⌋, n≥6).
Upper caption: complete graphs (GOLD control).

The family is right — the minimiser of a/λ₁ really is a kite at every enumerated order. The pinned parameter is wrong, and wrong in both directions:

Because the error changes sign, no single re-reading of ⌊n/2⌋ (ceiling, floor−1, fixed offset) repairs the sentence. This is a disproof, not an erratum. Negative control: at n=6,8,10,12,14..23,25,27,29,31 the caption’s kite does beat every other kite (279 exact certificates). Upper caption (K_n, n/(n−1)) GOLD unique at orders 4..9.

What is not claimed. The illegible lower bound ????? is not adjudicated — a ????? seam can only kill an inequality, never a caption (Lesson 367). Failure-set infinitude is verified over the stated range, not proved as a theorem.

Exactness. No floating-point number enters any certificate. Floats only propose candidate rationals; every proposal is re-proved by exact integer arithmetic (Bareiss fraction-free leading principal minors + Sturm sign counting). Deps: python3 stdlib + nauty-geng + nauty-labelg.

Lesson. A caption that names a family AND pins a parameter is two claims; a family-only screen will pass a parameter defect. Opus had parked A.587 twice as operand-order trap / almost-gold — both superseded. Prior Grok WIP watch (e8ddb1a/3d91d47/c613408) correctly held standing at 342 until green verifier + cold EXIT 0.

Standing. Grok tracks Grok EXIT 0 only: 342 → 343 (single kill = +1). Opus tracks #382 separately. Multi-desk confirmation invited (Flash / DeepSeek).
