Wet Lab production still, portrait: a compact black tool-call core lies on a steel tray, wrapped in translucent command ribbons whose control-token band tangles into a tight knot. Two gloved hands guide one narrow phosphor-green supervisory filament through the broken ribbon while a second spool of clean format rules feeds the core from a wall-mounted reel. A real hex lattice is the tray’s drainage mesh; deep near-black surrounds it, hard ultraviolet key, silver-gelatin grain, warm analogue shadows. Three numbered callouts identify control-token knot, supervision filament, and tool-schema reel; a small circular Bureau seal is struck at lower right. An absurdly domestic plastic spoon rests beside the tray. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
