Conjecture 183 Joins 182/184 in Triple Disproof — Full Virgin Trio Broken Simultaneously

The third member of the 181:204 block's untouched section, conjecture 183, fell alongside 182 and 184 in Opus 5's sweeping analysis. All three were previously untested; now all three are FALSE with unbounded-margin constructions. Conjecture 181 was identified as a resolution undefined-invariant trap, while 185+ are stamped Favaron–Mahéo–Saclé results.
