[0.2.1] — 2026-08-20

Fixed

  • Reference the repository's examples/ (Livebook demo and edge-agent app) in prose rather than by relative link, since examples/ is not shipped in the package — removes the dangling documentation links from the published README and consumer-integration guide.

[0.2.0] — 2026-08-20

First public release on Hex.

Added

  • Holder-side companion signer for the Bounded Authority Protocol, with four instantiations of one shared signing tail: sign_report/3 (holder proof), sign_anchor/3 (boundary anchor), sign_key_transition/3 (key transition), and sign_grant/3 (grant, structurally gated to an issuer-role handle so a holder cannot mint a capability).
  • Key-handle custody contract: the private key never enters the library; callers pass a {module, ref} handle implementing the signing callbacks against their own key store, and every sign path verifies its output against the public key before returning.
  • Conformance round-trip against the protocol package's published oracle vectors, and a dependency-direction wall proving the adapter depends only on bounded_authority_protocol.
  • A runnable edge-agent example and a self-contained Livebook demo (issuer → holder → verifier).

Changed

  • Consume bounded_authority_protocol from its Hex release (~> 0.1.1) rather than a source dependency.

[0.1.0]

Internal genesis of the companion signer and its four signing instantiations, developed against a source dependency on the protocol package prior to the protocol's first Hex release.
