Detailed Description

The chug margin over a burn uses the closure's own injector drops and SMDs.

The time-varying solve (and the runner's array path) passed the stability analysis only the flows
and tank pressures, so it fell back to placeholder drops (0.30*Pc injector, 0.10*Pc feed) and
SMDs (80/60 um): GM 1.290 against forward mode's 1.479 at the same point on the 6.8 kN engine.
Checked against forward mode, which passes the closure's diagnostics: at the same tank pressures
and t = 0 (no erosion yet) the two must agree.
