authweave-http-signatures

Payment HTTP Message Signatures profile (authweave-payment-http-sig-v1) for AuthWeave. Verifies RFC 9530 Content-Digest and RFC 9421 signatures after machine authentication (mTLS or DPoP), then binds keyid to the authenticated principal and consumes a signature nonce.

This package does not authenticate callers and does not implement business idempotency. Structured Fields parsing uses the maintained http-message-signatures library (RFC 8941 / RFC 9421).

PaymentHttpSignatureVerifier(..., observer=...) emits logical integrity and nonce-replay observations through the neutral authweave-core observer seam. verify(..., links=(TraceCorrelation(...),)) supports async/retry causality; linked trace context never participates in authentication or key binding.

Frozen/custom verifier clocks are request-local; the package does not mutate the process-global clock of the Structured Fields/signature implementation.

sign_payment_message is a local reference/test helper and accepts an in-process Ed25519PrivateKey. Production producers keep non-exportable keys in their own KMS/HSM signer and emit the same documented RFC 9421 profile outside this verifier package.
