Three things, all from parsing ptbtn0Nf.rat as a build.
1. THE RING SPINS. Its two keyframes differ in exactly one field: rotation_deg
ramps 0 -> 360 with position, scale, alpha and tint all constant. A spin in
place, the same shape as the GP_BUNK example already recorded.
2. THE ORACLE CONFIRMS THE GAME RENDERS IT. In the OPTIONS-focused capture the
ring's bright head sits in a completely different angular position from the
sprite's own -- caught mid-spin. This is a SECOND independent confirmation that
rotation_deg is drawn, now on a different screen and a different element from the
ptloop sweeps, and it raises rotation's priority: it is not a title-only concern
that sits off-screen at rest, it is the main menu's focus marker.
NO ANGLE IS QUOTED. A brightest-region centroid says ~250 deg, but the control
refuses that precision -- rotating the sprite by a known 30/90/180/270 and
re-measuring gives errors up to 19.8 deg. What survives the error bar is that a
<=20 deg error cannot manufacture a ~250 deg displacement.
3. WHICH PLACEMENT WINS -- correcting this page's own earlier caveat, which said
to use the leaf only for elements the parent does not declare. Right for a BASE
record, wrong for an f record: the parent declares NO element for ptbtn0Nf.rat at
all (zero of build 5's 16), so the f record's placement comes from its leaf for
BOTH elements, label included. The label's (-7,-7) is load-bearing -- the f
sprite is 13px larger per axis and -7 keeps them concentric (535+96/2 = 583 vs
542+83/2 = 583.5). Corroborated against the oracle: the focused-minus-unfocused
region is x 505..703, and the leaf predicts a right edge near 707 where the
parent reading predicts 714.
Also exposes UiBuild::records (name -> (offset, size) of a nested .rat leaf).
Nested records were parsed into a PRIVATE map, so a consumer holding a UiBuild
could not locate a leaf's bytes at all -- which is exactly what blocked the port
from reaching the ring.
