Detailed Description

The impinging closure never touches Cd, whatever solver.closure.Cd_reduction_factor says.

configs/default.yaml (the template every new session loads) and 13 other configs still carry
Cd_reduction_factor 0.95. With the spray constraints violated -- the 6500N's x* is 54 mm against
its 50 mm limit -- the closure multiplied Cd by 0.95 up to six times: Cd_O 0.80 -> 0.62, F -12 %,
and x* got WORSE (lower Cd, slower jets, bigger drops). Cd is orifice geometry and Reynolds
number (Lichtarowicz 1965; SP-8089); an x* or We violation is reported, not "fixed".

The expected Cd is the published sharp-inlet short-tube fit at the hole's L/d, less the Re term.

The authoritative Python path; engine/accel mirrors it and test_numba_ab_parity holds the
two together.
