Three captures, aligned by the sweep's position rather than by frame number. The plate's alpha goes 23,46,69,92,115,139 over ~11 frames with no input, and 255 in a single frame when A is pressed: zero intermediate values against eleven. A cuts, it does not accelerate -- the human's prior holds. The control is what makes it readable. Four elements ramp out right around the press and I could have reported that as the effect; at sweep x=-1.42 all three runs agree quad for quad, so those exits are the ordinary build-in. Refutes clock:"shared" on F4's own discriminator: the artwork keeps animating across the press, frame for frame identical to the control. Reach stated -- that half rests on a 5-frame window, since everything else on screen is already at 255 and cannot discriminate. Also records the first attempt's miss: blind wall-clock timing put the press after the settle, where A is accepted instead. The probe now gates on the sweep appearing, which is the parent's declared t=70..100 gate.

# Discriminator: pteff03's LEAF declares alpha 255 from its own t=0, while its
|
|
# PARENT ramps 0->255 across t=70..100. So in the drawn vertex colour:
|
|
# flat 255 throughout => the parent is NOT multiplied in
|
|
# a ramp 0->255 => it IS
|
|
# That also settles the port's own flagged ambiguity, whose stated separating
|
|
# interval (t=100..238) is the same one F6 is about.
|
|
#
|
|
# Simpler than the menu probe on purpose: ONE A press to skip the attract video,
|
|
# then no further input, so the title builds in undisturbed and stays.

# --- F5: a SECOND A during the title build-in ---------------------------

# wait for the sweep's texture page to appear (that IS title t=70..100, the

# parent's declared gate opening), then let a fixed number of frames pass.
