# arete-hash
Authoritative typed artifact identities and canonical hashing for Arete.
The crate implements the versioned `arete:h1` protocol, including strict hash
identifier parsing, JCS canonicalization, framed tuples, artifact trees, IDL
projections, and program release projections.
The address-free `arete.decoder-fixtures/v2` projection hashes as
`decoder-fixture-set`. Cases are validated and sorted by stable ID before JCS
hashing; exact account bytes and optional private diagnostics participate in
identity. The kind is marked `internal-only` and is not a public artifact
identity. Error expectations use the stable public account decode categories;
private diagnostics contain only trailing-byte and candidate counts.
Hosted managed `arete.program-release/v2` identities bind a strict legacy or
upgradeable Solana executable identity while retaining the existing
`program-release` kind and `h1` hash domain. OSS-generated release V1 identities
remain byte-compatible.
The shared conformance vectors live in `../test-vectors/hash-v1.json` and are
also consumed by `@usearete/hash`.
