Changelog #

0.3.0-alpha.1 2026-08-28 #

Adds STAR-lite v1: support for permissioned space repo archives.

Existing v0 archives parse as before, and kind-C archives (public repos) are still written as v0 by default.

star-lite #

Added #

• STAR-lite v1 format support.
• New header module: Version (V0/V1), Kind (Commit = C, LtHash = L), and Commitment (Cid or LtHash([u8; 32])).
• Kind-L archives for permissioned space repos
• verify_commit_archive and verify_space_archive return the concrete VerifiedCommit / VerifiedSpace for a known kind; verify_archive handles either and returns a Verified enum.
• encode_space_archive, space_commitment, and SpaceArchiveBuilder for writing kind L archives.
• Writer::write_space_header, write_header_canonical (v0 for kind-C, v1 for kind-L), and write_header_versioned.
• Reader::version, kind, commitment, meta, header_lthash, parse_commit, and parse_space_meta.
• space_archive example.
• Fuzzing!

Changed #

• Breaking: verify_archive returns a Verified enum instead of raw kind-C (Cid, Option<CommitInfo>).
• Breaking: Reader::header_cid() and friends are now fallible
• Breaking: Cid is now CidGeneric<32>, re-exported from star-repo.
• Breaking: reader::MAGIC is replaced by header::MAGIC_V0 and header::MAGIC_V1.
• star_lite_to_car rejects kind-L input with FormatError::KindMismatch.

Fixed #

• Reader's error paths did not mark the reader finished, so iterating with for entry in reader could yield the same error indefinitely.

Removed #

• Direct ipld-core dependency.

star-repo #

Added #

• lthash module: the LtHash homomorphic set hash, slightly specialized for atproto spaces.
• space module: SpaceMeta { rev, repo, space } with strict parsing.
• SpaceMetaError.
• Cid type alias and CID_DIGEST_SIZE.

Changed #

• Breaking: Cid is CidGeneric<32> rather than the 64-byte default.
• Updated sha2 from 0.10 to 0.11 (go fasterrrrr).
• Added a blake3 dependency, for LtHash element expansion.
