      "question": "What is the optimization goal?",

      "question": "How does it relate to packingsolver?",
      "answer": "The converter and format map produce packingsolver-style box input files, following the upstream parser expectation for bins, items, rotation flags, and parameters fields."

    {
      "question": "What makes the scenarios realistic?",
      "answer": "Dimensions and carton candidates are derived from public Packrift product records, while scenario families mimic ecommerce fulfillment review situations such as apparel returns, subscription bundles, warehouse restock, and marketplace replacement."

    {
      "question": "What should not be inferred?",
      "answer": "The fixture is not a live order log, price list, freight quote, inventory promise, maintainer acceptance statement, third-party endorsement, or solver benchmark result."
