pub fn signed_volume_against(solid: &BrepSolid, bar: f64) -> Result<f64, String>Expand description
solid_signed_volume_for_sign for a caller that compares the result with
bar and nothing else (the boolean assembly’s closed tail, the shell’s
orientation, the direct edit’s inversion check — 2026-10-17): the memoised
sign reading, whose verdict against the bar is the exact integral’s.
BREP_SIGN_READERS_EXACT=1 restores the exact read at those call sites,
for an on/off census. Read once.
