IV.R411 — IV.OP3 Status: SOLVED (τ-effective) after Sprint 7A
IV.OP3 (three-generation structure) SOLVED at τ-effective scope. Three independent topological proofs yield |gen|=3: homological rank, primitive winding census, lemniscate regions. LEP N_ν=2.984±0.008 consistent at 1.95σ. Unblocks: Sprint 7B (ν NNLO), 7C (PMNS), 7D (baryogenesis).
