Notes

PARTIAL: difftest 8854 cases (8238 fixture: 4712 review adversarial (fixtures/topology.loopuse/review_adversarial.json: every op on loop indices 0..23 of each B-rep, a deterministic subset of a 78120-case sweep that passed once), 1984 tolerance-limit IsClosed3d cases (every edge tolerance 0, 1e-15, -1e-12 or 1e-9, so gaps exceed XSectTol3d: the over-tolerance branch runs 176 times, 88 with bCheckAllGaps FALSE), 1110 on the 15 upstream .smb B-reps read by SmBrep::ReadFromFile, with and without RebuildUVTrimCurves, plus 432 on the prog_test my_test_topology wire network, wire edges and the plane / B-spline faces of topology.edgeuse_p2 incl. tiny, huge, pinched and sub-domain ones; 16 generated + 600 generated in code; 4000 more checked once), 7950 pass bit-identical, 0 failed, 904 deferred (topology.face_p3 366: SmFace::Notify around FlipLoopOrientation of every loop on a face; topology.edgeuse_p3 348: GetOrCreateUVTrimCurve in GetUVCornerBoundaries / the sector computations of IsMissingSeamAtVertices; inexact .smb geometry 190: topology.brep_p7 87, surface.sphere 45, surface.surf_of_extrusion_p2 33, surface.cone_p1 25), max_rel_err 0; --perturb SENSITIVE. Loopuse gains orientation (m_eOrientation); the shared B-rep export (sc_edgeuse_graph.h and the topology.vertexuse / topology.face_p2 / query.edge shim copies) and their importers carry it; the loopuse shim adds each face m_pFU (FaceFu op). Upstream bug WR-93: IsClosed3d never reports a loop open (ported as is). Wired: SmVertex::IsConnectedTo / SmEdge::IsConnectedTo -> topology::vertex / topology::edge is_connected_to (merge of main; the 99 vertex/edge-target cases now run on both sides); topology.edgeuse_p1 co-ports loopuse_edgeuses / loopuse_shell, topology.face_p2 loopuse_vertexuses, query.loop calc_quad_num and topology.vertexuse SmLoopuse::GetOrientation now call topology::loopuse (their difftests unchanged); UNPORTED(topology.loopuse) in intersect::point_class and surface::trim_srf_cache not wired (opaque handles without a Brep; plan/findings.md). Plan notes: 48 fns; largest: SmLoopuse::IsClosed3d, SmLoop::GetUVCornerBoundaries, SmLoop::FlipLoopOrientation, SmLoopuse::IsMissingSeamAtVertices; cycle back-edges (call into later units; stub or co-port): topology.edge(6), topology.edgeuse_p3(1), topology.face_p3(1); unit-SCC #22 (220 units); 319 upstream test entry points reach this unit; CO-PORTED in topology.edgeuse_p1 (PR #55): SmLoopuse members (owner face use, m_pL, m_pLUMate, m_tLoopuseType/m_pEUorVU) -> topology::{Loopuse, LoopuseStart}, SmLoop::m_pLU -> topology::Loop::loopuse; SmLoopuse::GetEdgeuses (no filters), GetShell -> topology::edgeuse::p1::{loopuse_edgeuses, loopuse_shell}; CO-PORTED in query.loop (PR #63): SmLoop::GetUVCornerBoundaries, sm_CalcQuadNum -> query::r#loop::uv_corner_boundaries, query::r#loop::calc_quad_num (private); they read the borrowed FaceLoop view of query::r#loop until the topology binds geometry.; CO-PORTED in topology.face_p2 (PR #91): SmLoopuse::GetVertexuses without filter -> private topology::face::p2::loopuse_vertexuses; CO-PORTED in topology.vertex (PR #96): SmLoopuse::GetVertices(SmTArray&) (no attribute filter), SmLoop::GetVertices -> topology::vertex::{loopuse_vertices, loop_vertices}; CO-PORTED in topology.edge (PR #103): SmLoopuse::GetEdges(SmTArray&) without attribute filter -> private topology::edge::loopuse_edges
