Module verify 

Pure ML-DSA-65 verification helpers for quotes and merkle candidates. Pure verification helpers for payment quotes and merkle candidates.

These functions inspect signed wire artifacts (PaymentQuote and MerklePaymentCandidateNode) and confirm their ML-DSA-65 signatures are valid. They do no I/O and do not touch on-chain state.

Both the client (when building proofs) and the node (when validating incoming PUTs) need identical verification semantics — keeping these functions in ant-protocol ensures the client and node cannot drift.

Functions

verify_merkle_candidate_signature

Verify a MerklePaymentCandidateNode’s ML-DSA-65 signature.

verify_quote_content

Verify that a payment quote’s content address matches the expected address.

verify_quote_signature
