bherbruck ab35fbb7bc v1.0.1 pin: second round of gate fixes 
- E3: in-place surface extension state on error (srf_adv extend_by_dist_in_place,
  extend_side), matching upstream's in-place surQ; finding + UB-107 addendum.
- S2b seam-path sites read lazy analytic domains through the made NURB
  (vertexuse compute_uv_point, face p1/p3, query face p3, curve_class p4,
  brep p1).
- query.face_p4 props import carries 1.0.1's raw seam touch lists and
  bad-crossed-seam flag; face_p4 runner handle answers as_loop/as_vertex;
  brep_p5 runner fmt; corpus child keeps stderr for failed files.
- api_queries runner hands face_entity snapshots to CurveOnClassify.
- WR-470 opt-in (precise_properties_body_length_scale) for SolidCraft
  3303 x3 / 451 join and the pole-sphere checks; default-path pin test.

// difftest shim for unit `query.face_p4`: SmFace::ClassifyLoops (source/SMLib/src/SmFace.cpp)
// on real SmBrep objects.
//
// One entry point, sc_query_face_p4_eval(op, path, in, n_in, out, cap, out_len). Layouts
// are documented in crates/solidcore-ffi/src/units/query_face_p4.rs, which validates every
// input. Every op starts with a B-rep block, then a case block `face props_mode loops_mode`:
// `0 rebuild validate_only init_gaps` SmBrep::ReadFromFile(path) (ASCII .smb)
// `2 surface u0 v0 u1 v1 validate_only init_gaps` CreateFaceFromSurface(surface, dom)
// `4 copies surf n_loops cnt* n_curves curve* n_pts pt* validate_only init_gaps`
// SmBrep::MakeFaceWithCurves over a real SmCylinder / SmSphere / SmTorus / SmCone or a
// B-spline / SmPlane, with 2D line and circle UV trim curves and single vertex loops,
// `copies` times into one B-rep (the faces of prog_test my_test_tsurf_cyl_creation_fast
// and of missing-seam faces: circles of a cylinder without seam edge, sphere caps and
// bands, torus bands)
// `5 surf validate_only init_gaps` CreateFaceInRegionFromSurface over the
// surface's natural domain (prog_test my_test_closed_sphere_properties)
// The B-rep traversal and export (Rd .. export_graph) are copies of the harness code of
// harness/cpp/shim/topology_face_p2.cpp (via query_face_p2.cpp), so the export has that
// unit's layout and traversal order (the Rust side imports it with that unit's importer),
// except that a face's analytic surface (sc_analytic_export.h) and an edge's ellipse or
// circle (sc_exact_curve_export.h) are preceded by their exact database record, which the
// importer rebuilds instead of the B-spline part when the record is lossless.
//
// The face props ClassifyLoops reads are built here as upstream's only caller,
// SmFaceProps::SetProps_Stage3, builds them before its call (props_mode 1): SetProps_Stage2,
// ReSet(SM_PROPSTAGE_3), then SmLoopProps::SetProps for every face loop, collecting the
// closed loops (a verbatim copy of SmFaceProps.cpp lines 1300-1341 without the debug
// blocks). props_mode 0 passes fresh props (ClassifyLoops runs SetProps_Stage2 itself).
// Op 0 exports the graph, the props (their values ClassifyLoops reads) and the target loops;
// op 1 runs ClassifyLoops and exports its results.
