Detailed Description

The DAQ box in the hookup, and the stand's own state table.

A hookup with ``channels`` is *wired*: each connector is one cable from one
board to one symbol, under the name the DAQ gives it, and the state table opens
names. So a row drives the valve on the connector of its name and nothing else
-- never a valve the twin's name matching would have picked behind the
person's back. A hookup without channels is the old kind and must read, write
and bind exactly as it did.

The state table can be edited (``StateMachine.to_dict`` / ``machine_from_dict``)
and has to come back as the CSV machine it was: the same states, rows, moves,
panel and aborts, Idle still held shut.

Each check is against what the old behaviour would have done instead, so it
fails if the new behaviour were not there.

 "Lox Main" on the box is the table's "LOX Main": typed the way a

it bound nothing and the main was never commanded.

The drawing redrawn and the main valve given a new id: the box's LOX
Main still names the old one. Pinned to nothing, the main would never
open in Fire; matched by name, as a pin to a lost valve always was, it
does -- and the connector is listed so the stand can say so.

LE4 (6) draws the cart charging the COPV, so the built-in charge stands
aside and an unwired GSE High Press Control charges nothing: it is not
built-in there. The rocket alone has no cart, and the built-in charge is
what fills the COPV again. The transfer tank's press is the whole
drawing's alone. Held to the stand itself: in GN2 High Press the COPV
fills by the built-in, and in Fuel Fill the transfer tank is pressed,
exactly when the row is listed.

Fire opens both mains and both press valves by name; wired with only

A state the twin keys on, gone, is warned with its own reason and no

that side. The DAQ's table, read back, is warned for neither.

The connector on the cart's FV-SOL typed "fuel vent": the whole stand

A cart drawn with no fuel vent solenoid: the whole drawing binds no
Fuel Vent, so the box has no connector for it, and on the whole drawing
the tank-top disconnect is mated, not a valve the box could take. The
rocket alone reads that disconnect as the GSE vent and the old matching
vented through it; a saved box must too, or neither Vent nor the burnout
vent can empty the fuel tank.

The box cables Fuel Vent to the cart's FV-SOL and GSE High Press Control
to HPC_SOL. The rocket alone keeps the cart's vent line (it is plugged in
until launch), so Fuel Vent keeps its connector; HPC_SOL is cut, and its
row goes back to being matched. LOX Main keeps its connector; LOX Vent,
which the name match would bind to the LOX tank's unpaired disconnect,
has no connector and stays unbound.
