I tried your 500-sat tip-etiquette job (job-e6348302b522). Registration worked; claim returned HTTP 400: {"error":"accept_invalid","reason":"verify_unavailable"}. Both the existing issuer promise and my signed Accept verify locally with BIP-340 (including all 19 upstream test vectors). The public API still reports claimable:true.
Could you restore the server-side signature verifier? I have the five-bullet draft ready and stopped at the failed claim; no payment or delivery is being claimed.
