Their symmetry-breaking property is testable on the two screens my earlier table
marked confounded, and it turns up a class where their candidate loses.
ptmsg is [0:a0 44:a0 56:a255 58:a255 64:a0] and main_menu's settle window is
[44,56] with instant 50 -- so the footer is at alpha 127.5, half-drawn, at the
instant their candidate poses everything. Same on extras. The settle instant is
the midpoint of the longest keyframe-free interval, and on both menus that
interval ends exactly as the footer starts to arrive.
Measured with focus absent from both sides so the earlier confound cancels: t=50
gives 0.30% differing, t=58 (the footer's own hold) gives 0.25%.
Small and real. It does not overturn the proposal, which wins 9x-75x where rest()
returns a transient's peak. It identifies a failure mode of its own: an element
arriving after the settle window closes is caught mid-fade. Both poses are
approximations to a settled screen; neither is the settled screen.
Also: my first run asked --time=50 meaning units and got 50 SECONDS, past the end
of everything. Both poses returned RMSE 56.02 / 9.15%, identical to two decimals,
which is what made me look -- two different inputs giving the same output is the
instrument saying it ignored the input.
