Confirmed correct level IDs (Streets=29, Egyptian=32, not the finding's
original level_20 guess). Source review clears both the unscaled-far-clip
and LOD-distance-multiplier hypotheses (bgfog.c/video.c both already scale
consistently). Narrowed to bg.c's portal/room-visibility BFS as the one
remaining suspect -- could be a real bug or just N64 behavior newly visible
on PC's sharp display; needs a live screenshot + location before touching
this decomp-verbatim system, not more static tracing.
Headless GE_PCDUMP long-sightline attempts on Streets/Statue/Egyptian did
not transfer from the D245 technique -- none of them have a scriptable path
to an open sightline without real level navigation.
