feat(iid): add canonical IID parsing and derivation (P02) - #22
Merged
Conversation
- Port the reference implementation from the private source (0xIntuition/intuition-v2 @ 8b9e9aa11): all 26 scheme canonicalizers, NORM-1, gen1 preimage/hash, geohash, UUIDv5/podcast-guid, keccak16. - Fix the parser value character class to the spec grammar (%x21-7E): space and non-ASCII values now reject as malformed, matching the normative parse vectors (recorded in iid-spec implementation-notes). - Redesign the identity-ladder contract around the public declarative source/recipe types (field, same-as, url-origin, geohash, podcast-guid, and the frozen named derivations) and implement the pure declarative derivation engine that interprets them; ladders are serializable data, never callbacks. - Add the typed inspection API (inspectIntuitionId) distinguishing malformed / unknown-scheme / noncanonical, with canonical repair for read paths, plus anchor-eligibility reasons (class-c vs polymorphic). - Execute the full 145-vector conformance corpus from @0xintuition/iid-spec in the test suite (212 tests) alongside ported and new engine tests. - Register iid second in the central package registry. Identity impact: none — no existing golden bytes change; all spec-stated golden values (ISBN upconversion, gen1 movie r4) reproduce exactly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
