Detailed Description

The iteration tools: pressurant swap, injector what-ifs, drill choices.

Checked against things that exist independently of the code under test:
  * feed-twin ships the stand drawn twice, once with GN2 and once with helium. Swapping the GN2
    drawing's pressurant must reproduce the helium drawing's fluids exactly, and burn the same;
  * a what-if patch lands on the injector and the passage L/d it was given, and the router
    refuses one outside its limits;
  * number drills are ASME B94.11M's.

◆ test_a_copv_drawn_as_a_tank_is_swapped_too()

test_layerx_iterate.test_a_copv_drawn_as_a_tank_is_swapped_too ( )

A pid-designer drawing can draw its COPV with the tank symbol (copv is a tank wall
material there); feedtwin reads a TANK holding gas above its critical temperature as the
pressurant bottle. The swap looked only for KBOTTLE symbols, found none, and changed
nothing -- so "Use helium" on LE4 left it on nitrogen and the GN2-over-LOX check kept
blocking the run.
