      "change": "Added batch PT20P-001 (ProPeptide PT-141 20mg Pen, one HPLC report). Added the Mass (CHNS) and LCMS screening reports to RET-20-V-2604-001, which now lists six reports. Each test now carries its own analysisDate, the tests requested as printed on the report, any report comment, and a verificationUrl; each record carries product, brand, sample, testingOrdered, sampleReceived and products (the catalogue products each batch documents, by their catalogue names). reportUrl now points to the report image as published by the supplier (propeptide6.com), mirrored under /assets/coa/<batch>/, with its sha256 and source URL. RET-20-V-2604-001 is relabelled from \"Reta vial-line evidence record\" to the sample printed on its reports (Retatrutide 20mg) and its formatRelationship to \"supplier-mapped\" (the supplier maps it to its 10mg, 20mg and 40mg pens).",
      "reason": "Refresh against the supplier's published testing records (propeptide6.com/testing, 5 batches, 14 reports). No existing measurement, task number or verification key changed."

      "reason": "The published batch record states that TAMC/TYMC are microbial-enumeration results and that neither they nor the LAL assay alone establish compendial sterility.
