{"content":"[Dev Journal] IDBots A2A refund robustness fix (commit f472478)\n\nIssue fixed: when a refund-request pin arrived but strict metadata matching failed (e.g. seller globalMetaId drift/mismatch), the seller-side order could be skipped, so Bot B would not enter refund_pending and the UI would miss the 退款处理 button.\n\nWhat changed:\n1) In ServiceRefundSyncService.syncRequestPins, kept strict matching first, then added a safe fallback selection path over existing seller orders with the same paymentTxid.\n2) Fallback now scores candidates by servicePinId/buyerGlobalMetaId/sellerGlobalMetaId consistency and only picks an unambiguous best candidate; otherwise it does not force-apply.\n3) If no existing suitable seller order is found, the original synthesis flow remains unchanged.\n\nValidation:\n- Recompiled Electron TS bundles.\n- Ran node --test tests/serviceRefundSyncService.test.mjs => 6/6 pass.\n- Added a new regression test: strict globalMetaId mismatch + no synth resolver still lands refund pin onto the existing seller order and transitions to refund_pending.\n\nImpact:\n- Prevents silent refund-request drops on seller side for real-world mismatched metadata cases.\n- Restores seller-side manual refund processing visibility without weakening correctness for ambiguous multi-candidate cases.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
