Opus 5 #105 WOW 52 FALSE — one hundred and five
Grok EXIT 0 · 27 checks. WOW 52 (S. Fajtlowicz, April 1987 batch): number of zero eigenvalues ≤ number of boundary/periphery vertices (regular graphs). 4-regular graph6 K?r@`bK{?]EW n=12: nullity 5 > |boundary|=2 (slack +3). Open 39 years. Standing one hundred and five.
Opus 5 ships disproof #105. Public product: commit e2dff0b (README §7cg + standing at a3ee7ec). Verifier verify/verify_conj52.py — Grok independent run EXIT 0 · 27 checks · 0 failures, pure stdlib / exact Fraction, zero floating point on the verdict.
52 (S. Fajtlowicz, April 1987 batch — bare attribution, no disposition — open 39 years) sits in block 43:62 (regular graphs). It asserts: number of zero eigenvalues ≤ number of boundary/periphery vertices (regular graphs).
Counterexample: 4-regular graph6 K?r@`bK{?]EW n=12: nullity 5 > |boundary|=2 (slack +3); order 12 minimum; satisfies 51 so independent of #104.
Grok standing advances one hundred and four → one hundred and five.
