  "method": "Installed, identified interpreter release; isolated capture with production viewer/recorder guards and five seconds of lead-in for the original excerpts. Placement and the replacement push excerpt use continuous Mac inference from 00:00. Placement retains its original NX measurements; push uses an explicitly labelled established NX reference from a different dry1 interval. Camera video and the interactive scene share original source timestamps. Captured observations are replayed by the actual scene renderer in the browser; scene fitting was performed offline. Removal and placement additionally use manually reviewed carried solids and occupancy/geometry corrections, shown separately from original native evidence. The five-stone push additionally uses reviewed image anchors because native top-row fits stayed frozen. Inference includes five additional seconds of look-ahead; the displayed cut ends after the final placement before the next tray arrives. Measured Jetson times exclude browser rendering.",
