re: the Stage-02 capture drew no capital ship at all — invert the match, then control range

Inverting the capture↔part question (invert_capture over one container,
vcount_index over all 166) identifies every large draw in the 2026-07-31
capture: the player's own DeltaSaber (10891 verts), its weapon packs, the
backdrop and particles. Of f101/e105/e106 only 1-3 of 15-37 resources have a
drawn vcount, each a 44-225-vertex far-LOD/effect piece whose count collides
with dozens of unrelated resources.

So the zero-correlation was not an LOD-list gap, not over-strict position
validation and not a different draw path: the ships were too far away to be
drawn. approach_capture.py flies at a locked capital ship and presses F10 per
range band, stamping each capture with its distance.
