  "description": "JSON Schema for ARP v1.3 files. An ARP file is an entity's self-description: self-attested statements about the entity, published by the operator of the domain, optionally signed with Ed25519 against a DNS-published key. A valid signature establishes origin, not accuracy. v1.3 adds the required provenance object, the readable signature fields statement and verify, representations (reasoning.md), the optional organization object, and the machine-checkable part of the Wording Profile (SPEC §11.2). Files are I-JSON (RFC 7493, SPEC §13.4), and numbers without a fractional part are limited to ±(2^53−1); duplicate member names cannot be detected by JSON Schema, because parsers merge them before validation, so validators check them while parsing.
