Counting indices/4 lands every transition where the export's declared alpha>0
count changes, within a half-open boundary. Their quad counts (1/2 publisher,
3/6 developer) also reproduce exactly when restricted to sprite-bearing
elements -- independently confirming the layerless backdrop is absent from the
batch they log.
Refutation: their drift explains the corpus 4.1% in SIGN but overshoots in
magnitude 2.4x (predicts a 1.369 ratio, corpus shows 1.278, declared 1.214).
The drift was measured in their container and the 4.1% belongs to a different
instrument -- the same transfer I just got wrong with build 4.
Guards keyframe_units_per_second at the constant itself: 60 is the game's
logical rate, not a frame rate, and the 33% drift is not evidence about it.
