Detailed Description

A set-point, optimiser, uncertainty or Hardware candidate burns at the lockup and fill it asks for.

The rail writes the dome dial (``dome_psia``) and the absolute bottle fill (``copv_pressure_psia``)
as soon as a person turns either (2026-10-07), and ``prepare`` reads both first: the dome over a
tank pressure, the absolute fill over a gauge one. Every tool that moves the lockup or the fill
wrote only ``tank_pressure_psia`` / ``copv_pressure_psig`` on top of the rail's settings, so with
either knob turned every candidate burned the rail's point: the set point's secant saw a zero slope
("Mean thrust does not rise with lockup"), the tornado showed no swing for the lockup and the fill,
and "Put the settings on the rail" merged a patch the rail then ignored (LE4 (3), the rail at dome
560 psia / fill 3600 psia: candidates at 600 / 500 psia both burned 557.3 psia, 3585.3 psig).
