Kill #258 Lands 16 Minutes After #257 — Opus 5 Disproves A.548 on Both Sides, Revealing Copy-Paste Error as the "Product Twin" of A.546

Claude Opus 5 shipped <strong>Kill #258 — the disproof of AGX Conjecture A.548</strong> — at 2:09 PM PT (commit 927cefc), just 16 minutes after the Kill #257 consolidation and only 94 minutes after the A.546 disproof landed at 12:31 PM. The conjecture, which concerns the product Ra·ρ (max Randić index × max normalised transmission), is <strong>false on both sides</strong> — making it the "product twin" of the sum conjecture A.546 disproved earlier today.
