RFP-02: Critical UV First-Passage Skeleton, Shell Carrier/Bypass Dichotomy, and Nonlinear Source Debt

Critical UV First-Passage Skeleton, Shell Carrier/Bypass Dichotomy, and Nonlinear Source Debt

RFP-01 rewrites the singularity problem as State+Edge+Guard+Escape+Closure, posing the two ultimate obligations Chain Necessity and Finite Obstruction. This round attacks Chain Necessity's first bridge: proves critical UV escape produces a regular nearby-scale first-passage skeleton, and produces equation-level nonlinear source debt on every non-synchronous edge.
