e.Mix OrcaTI Sysbrasil Tecnologia Vero Internet Zadara SNAP (Simple Native Archive Protocol) defines a minimal, self- describing backup object encoded as a single JSON document, modeled in YANG [RFC7950] and encoded per [RFC7951]. A SNAP object contains a manifest of files with per-file cryptographic hashes, integrity- verified metadata, and a compressed binary payload -- all within one atomic, transport-agnostic JSON document. Any agent capable of parsing JSON and applying standard decompression can produce or restore a SNAP backup without proprietary tooling, side-channel metadata, or multi-phase handshakes. This document defines the YANG module "snap", its JSON encoding, integrity verification procedure, bindings to common transports, and its role as the atomic transport substrate for the Multi-Vantage Path State (MVPS) family of Internet-Drafts. When a SNAP Object carries an MVPS Bundle [I-D.melegassi-ippm-mvps-bundle], the canonical-form determinism of SNAP (Theorem 1 of this document) composes with the MVPS Architecture axioms A1..A5 [I-D.melegassi-iab-mvps-architecture] to inherit the full coherence algebra of [MVPS-v4] (Theorems 1, 2, 3, 3', 4, 5, 9 and Stein's Lemma [Stein52] [CoverThomas2006]) without alteration.
