    "title": "A container receipt does not prove receipt of every inner specimen",
    "context": "A fictional core-support handoff uses cardboard boxes and paper labels. Abstract interval marks do not correspond to boreholes or subsurface locations.",

      [
        "MC1",

    "question": "Which BOX-R specimen has a confirmed receipt, and does the second R2 label close the custody gap for interval 2–3?",
    "answer": "MC1 and MC2 support a confirmed receipt of R1 from BOX-R for interval 1–2. They establish that R2 was listed in BOX-R, but not that the receiver confirmed it. MC3's R2 belongs to BOX-S and interval 8–9. The repeated inner label alone cannot establish receipt of BOX-R's interval 2–3 specimen. That custody link remains unresolved.",
