  "recorded_result": "The selected utrack.lws uses Utrack.lwo with set1.tga and set4.tga, and a button material names but_slecan.tga. The selected model has 249 vertices / 460 triangles with 460 matching UV records.",

    "Distinguish edpieces/Utrack.tga (256×256 sheet) from uedit/Utrack.tga (640×480 stored render). Follow UI record 0x4BCD60, piece ID 19, into the parsed scene list.",
    "The selected structure contains the blue Semi Logic can. The blue/flame illustration is preserved imagery, not recovered playable geometry or proof that Utrack as a whole was unused."
