Operational Auditability in Physics II: Fluctuation Theorems as Conditional Holding-Equalities (Jarzynski, Crooks)

This record contains the preprint “Operational Auditability in Physics II: Fluctuation Theorems as Conditional Holding-Equalities (Jarzynski, Crooks)” (Version 1.0). The paper reframes the Jarzynski equality and the Crooks fluctuation theorem as conditional holding-equalities under an explicit operational audit contour. The approach emphasizes clarity of assumptions, operational definitions, and trace-chain integrity (data provenance and transformation steps) required for independent verification. The manuscript provides a derivation roadmap and a reproducible two-channel validation protocol based on independent simulation and independent data-reduction, intended to support audit-friendly verification across heterogeneous implementations.
