A drawing made in pid-designer the way a person makes one. pid-designer's lines have no direction: "walking any line in either direction. What 'upstream' means on a drawing with no arrows" (its `checks.ts`). Which end is a line's ``source`` is only the end the mouse started at. The shipped stand drawings were authored in flow order, so reading ``source -> target`` as upstream to downstream happened to work on them; a drawing made freely broke on it. Run a press line *from* the tank *to* its solenoid and both of the solenoid's lines arrived at its inlet, its outlet hung open, and the press valve was read as a vent from the regulator to atmosphere. These pin the rule that replaced it -- the port a line was drawn on decides the side, but only where the old reading left a side with nothing on it -- and the two messages a user importing their own drawing actually needs.

LE4's COPV gives no volume. It was given a 44 L K-bottle, so a burn took 250 psi out of a bottle that really loses thousands: 45 scf of air at 4500 psi is a 4.64 L cylinder (4.6871 L with its fittings), the one the stand and the Study run.

No vent valve on the drawing: the pad's Ox Fill boiled TK-3 up to the 717 psig critical pin and the sequence never left it. The disconnect is where the cart's vent couples, so the table's LOX Vent opens it.

LE4's regulator dome line: a solenoid, then a quick-disconnect left open to nothing. With the solenoid shut that run is an island cut off from every fixed pressure. Peeled from both ends, the stubs met in the middle and left one node with no equation and no live end -- "the Jacobian could not be factorised" on every solve with the solenoid shut, which in a DAQ sequence that never commands it is every solve.

Nitrogen stated at 293 K is above its 126 K critical point: it can only be gas, so the TANK is the pressurant bottle. LE4 drew its COPV this way, and read as a propellant tank it could not even open (a propellant tank starts from a saturated liquid that does not exist there).

LE4's regulator is dome-loaded, with its dome filled through a QD rather
than by a drawn control regulator. Nothing exposed the dome, so the
cockpit's dome knob did not reach it and Layer X could not solve the dome
for a lockup ("Could not solve the dome setting"). It is a signal now --
and the press valves are still found through the regulator.

A QD with no coefficient is a fitting, priced as a bend. Capped, it is a stub, and the solver back-fills a stub at exactly zero flow -- where the bend correlation (Rennels, via fluids) refuses a Reynolds number of zero. The ValueError escaped a solve asked not to raise, on every solve of any drawing with a fill QD on it.
