      Add fetchWithReceipt and a persistible purchase context so buyers retain a facilitator receipt beside the original HTTP response and reuse the same authorization after restart or transport loss. Cover Arc exact USDC/EURC and native Hedera USDC; a confirmed payment can coexist with merchant HTTP 500. Expose receipt types, Ed25519 verification, private lookup and Express/Hono propagation.
