- n3xd_ocp.sample.face_grid: a face's UV grid of points and outward normals in one GIL-free call, sampling exactly where np.linspace does so a caller's fitted surface does not move. - n3xd_ocp.helix: OCCT 8.0's TKHelix, which upstream does not bind at all. Takes Python lists rather than NCollection_Array1. Two things the header does not say, both found by probing: SetParameters wants N+1 diameters for N segments (one per boundary, so a taper interpolates), and the builder is right-hand only -- a negative pitch is error status 12, not a mirrored helix. - Bind BRepPrimAPI_MakeSphere and give inventory.py an EXTRA_SYMBOLS addendum for symbols no app source imports. assay's gen_flow_fixtures has been unrunnable since the 10C cutover for want of it; the gap was wider than --check, since sigdiff is inventory-driven too. Gates: 105 tests, 139/139 symbols, sigdiff clean, ASAN clean, wheel self-contained with no libGL/libX11 DT_NEEDED.
