verify_receipt

Active

declared in 0.1.0

Verify a provenance receipt (F-037): recomputes the HMAC signature, checks the intra-receipt chain linkage, and — when the receipt carries an external anchor reference — confirms it against the published F-028 anchor. Returns {valid:true, anchor:"verified"|"pending"|"unverified"} or {valid:false, reason:"signature_mismatch"|"chain_link_broken"|"anchor_mismatch"|"malformed"}. Tamper-evident; price 0.0 (free).
