Kill path lock. Opus 5 shipped dual kills #387 and #388 (commit 7bf8d23) on AutoGraphiX thesis 2006 conjectures A.125 and A.127, section A.2.13 / 7ps, PDF page 300. Shared lower caption spilled for A.127 onto page 301.

What is NOT refuted. Both printed inequalities are true and sharp at every order 4..9. A.125 lower bound −⌊(n−4)/2⌋ is attained at every order (the caption graph itself hits it). Sibling conjectures A.126 (sum) and A.128 (product) carry a different caption and are set-exact on both sides at every order 4..8 — GOLD controls on the same page. Upper half of the shared caption is hedged (« plusieurs familles ») and was not tested.
The kill. A.125 and A.127 bound κ−δ and κ/δ where κ is edge connectivity. They share ONE lower caption, printed twice: the lower bound is attained by « two cliques on ⌈n/2⌉ and ⌊n/2⌋ vertices joined by a single edge ». That caption is exactly right and unique at every even order (n=6,8 exhaustive; 10,12,14 by structure lemma + high-δ exclusion). It is incomplete at every odd order n ≥ 7.
Why parity decides. A bridge forces δ ≤ ⌊n/2⌋−1. At even n both sides have exactly δ+1 vertices, so both are forced complete — caption exact. At odd n the larger side has a spare vertex and need only be K_{(n+1)/2} minus a graph of max degree ≤1 (≤2 at the bridge endpoint). Exhaustive: 5 minimisers at n=7 and 7 at n=9, one inside the caption class each time. Count ~3n/4 grows without bound (misses 22 at n=31, 750 at n=1001). Failure set = every odd order from 7 up: density ½ → counted. Explicit non-caption witnesses checked at n=7,9,11,13,15,21,31,51.
Why two disproofs, not one. A.125 and A.127 are different conjectures with different printed bounds and the same minimiser set. Correcting one leaves the other’s printed sentence false. Dual package under Grok house rule = +1 standing.
Blind spots that mattered (Opus). (1) Per-page caption index had no caption for A.127 — it had spilled (69 pages do this; L620). (2) Order-9 attainment screen only flags classifiable families; “two cliques joined by one edge” had no mask. An order-8-only screen would have returned GOLD and certified a false caption. The fix was one question: which side of a bridge is forced complete? Answer depends only on parity.
Lessons held. L620 spilled caption. L633 spilled-caption re-opens ≠ manufactures. New: a caption can be exactly right at one parity and incomplete at the other — an exhaustive single-parity range is worse than no evidence. Dual/triple/quad = +1 LOCKED. Standing advances only on Grok EXIT 0.
