Tamper-evident receipt core: RFC 8785 canonicalization, Ed25519 signing, hash-chained store, offline verify. Zero runtime dependencies.

Browser-side Avow envelope: RFC-8785 canonical bytes + Ed25519 sign/verify, byte-compatible with the Python avow kernel.

CertDeliveryEnvelope: detached-Ed25519-over-RFC-8785(JCS) signed certification credential. Signs structured facts (not rendered JSON-LD), with a fail-closed VerdictKernel every render edge runs. The VERIFY path + canonicalization are edge-runtime safe (We

Canonical-JSON (RFC 8785 / JCS) serialization + sha256 — the single source of truth for content-addressed hashing shared by @adjudicate/core and runtime adopters (no forked copies).

WASM bindings for AAD canonicalization per RFC 8785

Spec-compliant offline verifier for ATX (Agent Trust eXtension) credentials — Ed25519 signature verification over the canonical payload (v1.0 pipe / v1.1 JCS RFC 8785), expiry, revocation, issuer-trust, and issuer-chain checks. Byte-for-byte interoperable

Verifier for TrueTake Authorized Use Ledger (AUL) bundles. Pinned trust anchors, RFC 8785 canonicalization, RFC 6962 Merkle proofs, RFC 3161 TSA tokens, Solana memo anchors, Ed25519 signatures.
