feat(v1.0.1): P2 improvements — TolerantEdge + .vde format + boolean fallback
Build & Test / build-and-test (push) Waiting to run
Build & Test / python-bindings (push) Blocked by required conditions
CI / Build & Test (push) Failing after 24s
CI / Release Build (push) Failing after 31s
P2 — TolerantEdge (ACIS):
- TolerantEdge: tube_radius, path_tolerance, is_within_tube, intersects
- detect_tolerance_conflicts: VertexInSphere/EdgeInTube/FaceGap
- resolve_tolerance_conflicts: auto merge vertices/edges/gaps
P2 — .vde Native Format (ACIS):
- Binary format: VdeHeader(32B), 6 SerializationSections
- save_vde/load_vde: full B-Rep topology + geometry + tolerance + attributes
- save_vde_json: debuggable JSON export
P2 — Boolean Fallback Ladder (Parasolid):
- 4-level cascade: SSI → tolerant → mesh → SDF
- Level 4 never fails (SDF + MC mathematical guarantee)
- BooleanFallbackResult with per-level diagnostics

feat(v5-M4): industrial formats + GPU acceleration + Python bindings
CI / Build & Test (push) Failing after 35s
CI / Release Build (push) Failing after 41s
Build & Test / build-and-test (push) Has been cancelled
Build & Test / python-bindings (push) Has been cancelled
M4.1 — 工业格式 (Agent #0):
- JT parser: ISO 14306 Segment→Part→Mesh/LOD, XT B-Rep decode
- Parasolid XT: text/binary parser, Body→BrepModel mapping
- ACIS SAT: text format parser with version handling
- IFC: SPF parser, IfcWall/Slab/Beam/Column entities
- STEP AP242: PMI annotation + tolerance export
- 47 tests covering all formats + edge cases
M4.2 — GPU 加速 (Agent #1):
- CUDA kernels: mc_kernel, qem_cost_kernel, tri_intersect_kernel
- __constant__ memory for edge tables, atomic triangle collection
- CPU fallback when CUDA unavailable (seamless degradation)
- VDE_USE_CUDA CMake option, .cu compilation support
- 9 tests with CPU path validation
M4.3 — Python 绑定 (Agent #2):
- vde_brep: BrepModel, make_*, boolean, STEP/IGES, heal, validate
- vde_sdf: primitives, operations, to_mesh, gradient descent
- vde_cam: roughing/finishing/drilling, Tool, ToolLibrary
- vde_assembly: Assembly, AssemblyNode, interference, explode
- Version: 3.3.0 synced across pyproject/setup/__init__
