Detailed Description

The supply-pressure effect, measured from zero inlet.

``outlet = dome + bias - S x inlet``, the inlet in gauge: a 1092-50 loaded to
500 psi with 4,500 psi behind it at 17 psi per 1000 holds 473.5 psi, and comes
up as the bottle falls (the team, 2026-10-07). It used to be measured from a
datum -- a drawn ``inlet_reference``, or the COPV charge -- which zeroed it at a
full bottle; the study drawings declare one, 4,500 psi, and it is no longer
read.
