The complete Mac body consumes a tagged object unit, follows its existing object payload and compares a record byte to1, then normalizes the full EAX result to0/1. Its sole native caller passes a target unit from the dynamic path's typed target field and tests the full result. Recover only D2UnitStrc* input and four-byte BOOL, retaining the current FUN name, chosen pUnit, one Stack4 slot and cdecl. The record-byte semantic label is disputed and remains held; no door name, field meaning, layout, table type or Windows pairing is proposed.
