    "answer": "CPR2 confirms O1's return to depot D and explicitly links L1 and L2 as successive labels on one object. CPR3's redelivery is only a proposal, with no later dispatch or receipt for O1; the O2 near-match cannot advance its history. Report D as the last confirmed custody point and preserve the unsuccessful attempt separately. Two labels do not imply two parcels or completed redelivery.",
