A trap pit 1.05 m deep and 2.3 m across, revetted with fourteen pine posts, with thirteen sharpened stakes leaning in the bottom and a cover of eleven sticks on two ledges under a mat of brush that lifts on the -Z lip. The origin is the pit floor, not the rim: sink the model until the spoil lip is level with the terrain. Dimensions 3.10 × 1.34 × 3.10 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Damp conifer forest realism: wet concrete and corroded corrugated steel, weathered pine, dark bark and soil, deep needle green, olive canvas, gunmetal and machined steel, with five emissive colours (amber fire, white floodlight, green status, blue screen, red warning) that also form the loot rarity ladder. Rigid node-transform clips open, close turn named nodes on their own pivots. No skinning, no skeleton, no skin weighting, no collision or navigation data.
