From e7aef60e53f8989c38feb4350273718b2d89eca5 Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" Date: Thu, 15 Oct 2026 15:38:10 +0100 Subject: [PATCH] feat(canonical): JCS (RFC 8785) canonical JSON, verified against the estate's ijson-jcs crate; the KYAML ratchet src/canonical.jl adds MetaManifold.Canonical -- jcs_bytes(x) and jcs_sha256(x) -- the deterministic byte form of a JSON-shaped value for hashing, signing and content-addressing: object keys sorted by UTF-16 code unit (so an astral-plane key sorts before a high-BMP key, the trap naive code-point ordering misses), Float64 values serialized per ECMAScript's Number::toString (shortest round-trip digits, positional between 1e-6 and 1e21, a signed exponent outside it, -0.0 collapsed to 0), integers outside I-JSON's exact range and NaN/Inf refused as no consumer reads them back as the same value. The oracle is the estate's ijson-jcs crate (Rust, RFC 7493 + RFC 8785): the eleven cases in test/fixtures/jcs_oracle.jsonl were PRODUCED by that crate, and test_canonical.jl asserts this implementation reproduces every one byte-for-byte -- key sorting including the astral case, the ES number table (4.50, 2.4499999999999998e16, 1e30, 1e-6, 1e-7, 1e21, 1e20, subnormals, -0.0), string escaping, nesting, literals -- plus hand-written testsets for key-order irrelevance, the refusals, and the content-address property (a chart spec built in any key order hashes identically). Verified 22/22. KYAML (YAML-POLICY Y-3): the standards repo's kyaml-format.sh is adopted verbatim, and a ratchet testset runs it --check over every tracked *.kyaml. Tool-named files keep their extensions per D307, and the shared config defaults convert as an upstream unit rather than unilaterally -- this repo's YAML is upstream-shared or tool-named, and the policy's own sequencing calls unconverted files backlog, not violations. New estate-owned YAML config is written as .kyaml from now on, and this gate holds it to form. Stacked on #157 (the root-completions PR); rebase onto main once that lands. Generated by Mistral Vibe.
