frame_geometry.py snapshots each SEND payload (deduped by content) and pulls
fixed-point screen coords. Honest outcome: only 11 sparse coords, all in the
object's x-range, no terrain -- the payloads store compiled edge/plane
coefficients, not extractable vertex lists, so "grep coords and plot" is a dead
end. A real from-scratch render needs the full plane-role assembly (slopes +
constants -> lines -> triangles -> array), which stays unsolved. Documented in
MICROCODE-DECODE-NOTES.md so the shortcut isn't retried.
