Numbered errata against published normative documents, per the governance policy (published in governance.md; authoritative source in the standards track charter § Governance). An erratum may clarify prose, correct non-normative text, or add conformance cases. No erratum may change a verdict of an existing certified corpus: any change that would alter such an accept/reject outcome is a contract-major change and follows the evolution contract, never this registry. The one exception is a soundness repair (governance § Soundness repairs, ADR 0040): it changes verdicts only from accept to reject on producer-impossible inputs, adds its cases in a new additive corpus, and leaves every existing corpus verdict unchanged.

Each entry records: number, date, affected document and versions, the correction, and its conformance-corpus impact (which must be additive or none).

12026-08-24docs/protocol-v1.md and the standalone/embedded selector schemas as published in package versions 0.1.0–0.1.2An all selector is valid on exactly the three recognized selector member sets; path and value/values are inert when present. No other member set is accepted. See ADR 0021.None: corpus bytes, 283 verdicts, and the certified index SHA are unchanged.
E-2026-09-17-12026-09-17README.md (published Hex 0.4.1)The 0.4.1 package's README records checksum 8544a9ff…358a9 (the pre-publish mix hex.build inner-tar checksum) where the registry checksum belongs. The 0.4.1 registry checksum is 4648f545f681d540c965d460411133cf6188066439dbc37fc869288f9fcad1cf (read back from the Hex release API); README on main is corrected. Consumers verify package identity against the registry, not the shipped README string.none
22026-10-12spec/bap-v1.md, spec/bap-v2.md, and the local-loopback, role-attestation, and content-assertion profile specifications, as published through package version 0.7.0Soundness repair (ADR 0040): Ed25519 verification is strict. Point encodings must be canonical, small-order keys and R values are rejected, S must be below the group order, and the cofactorless equation is mandatory; public keys must pass key acceptance; hosts must check torsion-freedom at enrollment, trust install, and deny-list comparison. See the security advisory.Additive: the new bap-strict-ed25519/1 corpus (2,410 cases; index SHA-256 732117dfe1881b553998126a9524a95bfb1171257e388d5430a0a099f2287cb9). Every existing corpus index, its cases, and its verdicts are unchanged.
