Three fixes, all of them found by pointing the thing at celestrak.org and
looking at what came back.
**The catalogue was 100% Starlink.** The supplemental feed is 10,766
objects against a 6,000-object ceiling, so a first-wins merge spent the
whole budget on it and served a sky with no ISS, no GPS, no weather
satellites — every other group fetched, parsed, and thrown away. `merge`
now reserves the ceiling for the small groups and lets the fill group
take the remainder: 1,044 of everything else and 4,956 Starlinks. The
truncation warning is what caught it, which is the argument for the
no-silent-caps rule; it now reports the split rather than only the fact
that a cap was hit.
**You could get outside the sky.** The dome sat at 1.2 board spans and
the camera orbits to 1.5, so pulling all the way back put the viewer
outside it looking in, with half the constellation behind the camera.
2.0 is inside the far plane at 3.0 and outside the orbit.
**Size attenuation was wrong in principle.** A satellite does not get
bigger because you zoomed the map in. Fixed pixel size, at roughly what a
naked-eye Starlink actually looks like — the attenuated version shrank to
sub-pixel specks at the far end of the zoom and read as noise.
Measured over San Francisco at 21:19 local: 324 above the horizon, 267
fully lit, 96 at local midnight. The terminator does what it should.
