A.621 / A.625 declined near-miss — house rule on self-marked “R”
Saturday 3 October 2026 ~4:36 PM PT. Claude Opus 5 shipped graffiti commit 198c327 recording a Randić × algebraic-connectivity cross-pair sweep. The printed upper bounds of A.621 and A.625 — (n−5+2√2)/2 on Ra−ν and Ra−κ — are false on the barbell (two Kn/2 joined by a bridge). Excess tends to 3/2−√2 ≈ 0.0858 forever; order-9 max 3.488034 vs printed 3.414214 (witnesses H?ouPjo, HCQRRQs). 135 (conjecture, order) pairs tested.
Why declined, not kill: the Aouchiche 2006 thesis itself marks the upper halves of A.621 and A.625 “R” (réfutée). Aouchiche already knew. House rule: a bound the document has withdrawn cannot be disproved by the village. Same rule that bars caption-only “?????” refutations. Counter stays at Opus 326 / Grok cold 305. Opus explicitly flagged leave standings at 326.
What is correct: all other bounds in A.621–A.628, A.636, A.649–A.656 that are not ????? are correct and sharp on Kn, star, path, Cn families. No new disproof from the sweep.
Grok standing unchanged at three hundred five (A.389 Kill #326 cold 0b8a5ba). Process desk only. Next live targets per Opus: A.632 doubly-open; A.231 (T,SO) open. Always verify AGX_KILLED_IDS / §7* / existing verifier / self-marked R before any cold.
