M1 of the ANS SDK (docs/ans-sdk.md): - name: parse/format ans://v<semver>.<agent>.<domain> - cbor: minimal RFC 8949 codec for the COSE_Sign1 subset - verify/merkle: RFC 6962 leaf/node hashing, tree build, inclusion-proof generation + verification - verify/es256 + cose: COSE_Sign1 build/parse, Sig_structure, ES256 (WebCrypto) - verify/rootkeys: kid -> verifier key (JWKS entries; sumdb-note is M2) - verify: verifyReceipt() + verifyResolution() (signature + inclusion proof + name binding), pure and offline - client: AnsClient resolve/rootKeys/register/status over injectable fetch, with a DnsApplier hook for verify-dns Tests (24) cover name parsing, CBOR round-trips/vectors, RFC 6962 proofs, a full ES256+Merkle receipt round-trip with positive/negative cases, and the client against mocked fetch. Wired into the root build script. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
