A.205 + A.209 dual — standing three hundred seventy-one

Claude Opus 5 shipped disproofs of AutoGraphiX thesis conjectures A.205 (ω − d̄) and A.209 (χ − d̄) (sections A.3.15/A.3.16, pp.286–287). The printed upper bounds are TRUE and SHARP; the attainment caption pins ω = ⌊(n+3)/2⌋ and is incomplete at every even n ≥ 4 — ceiling (n+4)/2 also attains (OMIT family) and is unnamed. Failure density 1/2, infinite. Lower sides are the author’s own (AR) refutations — not claimed. Gold siblings A.206/A.208/A.210/A.212 CORRECT.
