The shared, version-pinned canonicalization library consumed identically by signer and verifier. Any divergence here breaks every signature, so this package is tested hardest. - body.ts: canonical body (§5) — UTF-8 validation, CRLF/CR→LF, per-line trailing whitespace strip, exactly one trailing LF; content_hash. - frontmatter.ts: byte-boundary split at the closing `---` (§5 step 1) and YAML→JSON-data-model parse (core schema keeps timestamps as RFC 3339 strings; Date defensively coerced). - jcs.ts: RFC 8785 canonicalization (via `canonicalize`, re-typed). - payload.ts: signing payload = JCS(frontmatter*) || 0x0A || canonical body, removing only provenance.signature.value. - index.ts: canonicalizeConcept() convenience + re-exports. Tests (28): RFC 8785 key-order/number/escape vectors; §5 body cases; invalid-UTF-8 rejection; CRLF/trailing-ws hash-identical; key-reorder → identical JCS & signing payload; signature.value does not affect payload. build + test green.
