RFP-03: Dual-Witness Parent Ledger, Exact Triadic Provenance, and Carrier-Depth Escape

Dual-Witness Parent Ledger, Exact Triadic Provenance, and Carrier-Depth Escape

RFP-02 has already upgraded Blowup(T*)⟹critical UV escape into Blowup(T*)⟹regular nearby-scale first-passage skeleton. This round uses dual normalized witnesses to construct, for every source-paying first-passage edge, an exact signed dyadic parent-output ledger; proves parent-cancellation and multiplicity debt, Fourier-support ancestry guards, and a classification of subsequence parent-gap/carrier-depth concentration escape.
