    "answer": "RS1 and RS2 trace DEMO-S1 through chain C and receipt L1 to result R1. RS3's DEMO-52 conflicts with the dispatched DEMO-S2 identity and lacks an approved correction, so R2 cannot be confidently attached to S2. Neither chain supplies a clearance decision. Report custody association, abstract result lineage and missing professional decision separately instead of treating a received result as approval of a real site.",
