UPIP: Universal Process Integrity Protocol — A Self-Validating Specification

We present UPIP (Universal Process Integrity Protocol), a five-layer protocol for capturing, bundling, and verifying the complete integrity of computational processes across machines. Unlike traditional reproducibility approaches that describe a method and hope the reader can follow it, this paper validates itself: it is generated by a deterministic script exported as a UPIP bundle. Reproducing the bundle regenerates this paper, proving the protocol works.
