Tags: icml2026-repro paper-HDoWJi2jlj

This logbook audits the five anchored claims for arXiv version 2507.17026v2. The evidence is independently authored. Claims 1-3 are answered by independent derivation plus executed sweeps on the paper's own toy construction; claims 4 and 5 are answered by a from-scratch reimplementation of the paper's NPE validation benchmark with all five competing methods (C2ST, Conformal Uniform(1/10/50), Conformal Multiple, SBC(200), TARP(200)) at the Table 1 budgets, 200 trials per cell. The result is VVVVV.

The referee-facing material is in pages/**/*.md. The source and authorship records are included separately so the claim pages remain focused on the mathematical and evidentiary record.
