Proof of Process (PoP) CDDL Schema

This document provides the normative Concise Data Definition Language (CDDL) schema for the Proof of Process (PoP) protocol. The schema defines the CBOR-encoded wire format for PoP evidence packets, semantic editing event transcripts, time anchors, signed tool receipts, compact evidence references, and verifier-produced attestation results. The schema is published separately to enable independent tooling, validation, and schema versioning decoupled from narrative specification text.
