Bins were cut on this corpus at 240×135@16 (CLEAR_PX 25, motion floor 19 px). Margin bins: a near-edge band [1, 1.25) above the gate boundary, then corpus quantiles; salience bins: a visibility floor, then quantiles.

Axis 1 — margin (the gate quantity as a clearance ratio; ≥ 1 passes)

cover_max / 0.15; 'neither': rect_gap / 0.5 · measurable on 110 questions

margin binnumeric range
near-edge [1,1.25)[−∞, 1.25)
bin0[1.25, 3.057)
bin1[3.057, ∞)

Ask: is this the same quantity the gate certifies on for this type? Are the states (e.g. 'same', 'gone') the right one-bin exceptions? Are the edges where a change in difficulty actually happens?

Axis 2 — salience (how visible / how large the motion is)

bin0[0.0007716, 0.009444)
bin1[0.009444, 0.01586)
bin2[0.01586, ∞)

Ask: does this axis capture what makes a question of this type perceptually hard, independently of the answer? Is the floor the right anti-gaming boundary?

Axis 3 — context

property of the correct answer (branch 2): occluder's role ('neither' when none) · labels: mover, neither, static
