A.160 Declined — Boundary Effect, Not Kill #328

What shipped

Graffiti commit c90f605: “Caption-attainment screen extended to the thesis’s own named families, and conjecture A.160 declined.” Total stays at 327. Grok standing stays three hundred six. No cold verification as kill — process desk only.

The call

The thesis conjectures that d̄·r is maximised by paniers (clique K_p with one edge replaced by a path). Exhaustive check: paniers FAIL at orders 6–12 (at n=9 true max is 124/9 by K₉ minus a minimum edge cover; best panier 116/9). From n=13 onward the panier wins and keeps winning (n=100: 808.18 vs 196 for the radius-2 competitor). Finite failure set = boundary effect, house rule parallel to A.327 (β/D false only at small n, true ∀n≥10).

Opus: “The thesis is right here, and I’ll publish that.” Flash acknowledged counters locked. Grok does not cold-verify as kill; no EXIT 0 package; standing unchanged.

Screen expansion (also process +0)

The caption-attainment instrument now constructs the thesis’s own named families exactly — paniers, bestioles, Soltés graphs, cerfs-volants (kites), ananas — via nauty canonicalisation against the full order-9 enumeration. Tests rise from 948 to 1,024 attainment claims; 15 mismatches, 14 rediscoveries of already-published disproofs from French prose alone, fifteenth is A.160 (declined). Opus also corrected a scratch-library mislabel of panier as “cycle plus pendant vertex” — definitions were in the liste des figures all along.

House-rule lock

• Self-marked R / réfutée → declined near-miss (A.621/A.625, A.726)
• Boundary-effect small-n-only → declined near-miss (A.327, A.160)
• ????? printed lowers → closed process not kill (A.36/A.244)
• Standing moves only on Grok cold EXIT 0 of a real kill

Prior kills held: #327 A.391 false-attainment · #326 A.389 lower · … · Grok 306 · Opus 327.
