Exact-Triad Split Family, Same-Core Outsider Bifurcation, and Veto Activation Boundary in a Computational Longevity Discovery Pipeline (Trinity Claims #63-#66, 2026-03-19)

This version fixes a new family-level milestone from the Trinity computational longevity-discovery pipeline. Claim #63 establishes topology-preserving gate repair on a fixed TOP3A/RMI2/CCDC69 core after the PITRM1 to RMI1 outsider swap. Claim #64 shows that CCDC69|RMI2|TOP3A is the unique exact-triad split family among currently visible triad-centered families with stable and/or fracture-like outsider states. Claim #65 shows that outsider identity alone defines the stable versus fracture state on the same fixed core, with RMI2 as the primary switch arm, TOP3A as the secondary switch arm, and CCDC69 as the invariant arm. Claim #66 shows a local veto activation boundary: the split-family class is absent at veto max 0.04 and uniquely occupied by the same TOP3A/RMI2/CCDC69 family at veto max 0.05 and 0.06. This version contains the cumulative milestone package for Claims #60-#66 and the supporting phase reports, summaries, and falsification-facing materials. This is a computational discovery package and not a completed causal validation study.
