    "title": "An assay amendment changes only the entry it names",
    "context": "This fictional certificate pack contains gold and silver fields, a valid one-entry amendment and an unconfirmed message. Values are arbitrary and must not be used for valuation.",

      [
        "PA1",
        "Certificate C-20",

    "answer": "PA2 changes A7's gold entry to 2.4 units and explicitly leaves the other C-20 fields unchanged. A7 silver therefore remains 8 units under PA1, and A8 gold remains 3 units. PA3 has an unverified alias, a different unit and no authorized supersession link. It cannot replace A7 silver or any A8 entry.",
