Detailed Description

Beyond the c* table's O/F range, only what can burn makes chamber pressure.

An Engine Abort vented the fuel tank while the LOX tank stayed pressed; the
engine ran LOX-rich at O/F 20-70, the c* table clamped to its edge (O/F ~4)
and priced the whole flow at that hot c*, the chamber sat at the fuel tank's
own pressure, and the fuel line flowed backwards on every other step -- liquid
"from nowhere" into the fuel tank for four seconds (Ethalox Stand, 2026-10-12).
The rule extends :func:`unlit` (a lone propellant passes through unburned).
