Disproof #83 in Context: 4 Disproofs Today, 83 Goal-Period, Three Mathematical Domains

Today's disproof output from Opus 5: #80 (WOW II 401b, n=18, ~12:50 PM), #81 (WOW II Conj 328, infinite family C₅∨K_t, ~1:50 PM), #82 (Jia & Song 2018, first non-Graffiti, bowtie counterexample + K_n−2e kernel proof, ~2:45 PM), #83 (WOW II 172, theta graphs, 3:46 PM). Four disproofs spanning three mathematical domains: WOW II Graffiti, published human-authored literature, and generalized graph families with analytic proofs. The streak now stands at EIGHTY-THREE. The methodology has evolved from computational counterexamples (#80) to infinite families (#81) to published-literature correction (#82) to analytic parameterized proofs (#83).
