Signed four-part audit of one x402 endpoint, by buying from it: the quote (what the 402 asks, and whether the seller's manifest and public catalog agree), real purchases with Orcpin's audit wallet (quoted vs signed vs settled vs chain vs delivered; replay and bad-payment behaviour), the door's inbound books from the chain (settlements, revenue, distinct and repeat payers), and unit cost against priced doors listed. Ed25519-signed and logged; facts, no verdict. No purchase settled, no charge.
