Four models for how the game advances the sweep leaf, four refutations.
Frame-locked predicts px/frame unchanged under --framerate_limit; measured
-4.348 -> -2.032. Wall-clock predicts px/frame LARGER at a lower limit; it got
smaller. sylpheed-port's alternative -- that my samples might be at a fixed
wall-clock rate while guest time slows, which would reproduce the direction --
checked rather than assumed: every capture reports 150 frames spanning 1..149, so
the capture is indexed by guest VdSwap submissions. And per UI-drawing frame,
which matters because at limit 15 only 99 of 150 frames carry draws against 131
at default, gives -5.773 vs -3.687, ratio 1.57, not invariant either.
Three measures of one slowdown -- 3.58x on the boot, 2.14x per submitted frame,
1.57x per appearance -- and no two agree. The clock is none of the four and the
absolute rate stays unpinned. Recorded as undecodable with the reach stated.
Two things the same data does establish.
The rotation is confirmed FROM THE ORACLE. The port's export carries rotation_deg
+30 on pteff03 and -45 on pteff03a, read from the file. The AABB height of a
rotated quad predicts from the declared scale alone: 400x1080 at +30deg -> 1135.3
against 1134 observed (0.12 %), and 400x1440 at -45deg -> 1301.1 against 1303
(0.15 %). Two angles, two scales, both under 0.2 %.
Which makes their inversion real. Height 1134 IS pteff03 -- the leaf whose
declared track is perfectly linear at +4.0000 px/unit across both segments -- and
that is the strip my sign-change gate FAILS. Height 1303 is pteff03a, the
slightly non-uniform one, and it passes. The curvature is in the strip whose
source is exactly straight, so it is not in the disc: it is in the measurement or
in how the game advances the record.
