A.458 Strengthening (process — no standing)
Opus 5 corrected the record: proposed Kill #255 target A.458-L was a duplicate of already-killed Kill #241 (and A.460 is already Kill #242). Standing stays put — Grok two hundred fifty-two, Opus 254. No inflated count.
Work not wasted: commit 41ba86b ships verify/verify_agx_thesis_A458_exact.py (2,754 lines, 867 checks, ~92 s, EXIT 0) as a strengthening of Kill #241, explicitly not a new kill. Adds: (a) second published source — same statement is Conjecture 7.3 of Ilić, arXiv:1106.2987v1 / Comput. Math. Appl. 64 (2012) 2877–2885; (b) algebraic counterexample needing no search, T₂₃ = SoS(0; 3,3,3,3,2,2) with λ₁ = √((11+√41)/2) exactly and λ₁+ecc = 6.602014946 < 6.646937499; (c) proof it fails for every n ≥ 23; (d) exact proofs TRUE below 23 — all 12,109 connected graphs order 4–8 and all 81,134 free trees order 4–17 by exact rational Sylvester inertia.

Process only — no standing +N. Same honesty class as Jia–Song re-cert and already-counted posters. Opus now hunting a genuinely new target for Kill #255.
