feat(v4.6): memory pool + parallel boolean/MC/intersection + GMP exact predicates
CI / Build & Test (push) Failing after 16m56s
CI / Release Build (push) Failing after 24s
Build & Test / build-and-test (push) Has been cancelled
Build & Test / python-bindings (push) Has been cancelled
M1 — Memory Pool (内存池):
- ObjectPool<T>: O(1) acquire/release with free-list, chunk-based expansion
- ThreadSafeObjectPool<T>: per-thread local pools with global fallback
- CowPtr<T>: copy-on-write smart pointer with shallow/deep copy
- 10 tests: single/multi-thread, CoW detach, reuse rate
M2 — Parallel Boolean (并行布尔):
- parallel_face_face_intersection(): OpenMP face-pair dispatch with AABB culling
- parallel_classify_faces(): thread-safe ray casting classification
- parallel_mesh_union/intersection/difference + B-Rep variants
- Thread count management API
- 12 tests: coverage, empty cases, identity operations
M3 — Parallel Marching Cubes (并行MC):
- parallel_marching_cubes(): Z-slice parallel voxel processing
- parallel_adaptive_mc(): octree-based adaptive resolution
- Complete 256-entry edge table + Möller-Trumbore interpolation
- 5 tests: sphere basic/high-res/empty/adaptive/threaded
M4 — Parallel Surface Intersection (并行求交):
- parallel_curve_intersections(): per-pair parallel dispatch
- parallel_surface_intersection(): recursive subdivision + Newton refinement
- AABB broad-phase culling before narrow-phase
- 4 tests: curve pairs, surface batch
M5 — GMP Exact Predicates (精确谓词):
- exact_orient2d/3d: adaptive precision (double → GMP fallback)
- exact_in_sphere: circumsphere test with degenerate handling
- exact_point_in_polygon/polyhedron: robust ray casting
- PrecisionMode: Fast/Adaptive/Exact with global toggle
- 12 tests: all orientations, boundary cases, mode switching

feat(v4.4): complete remaining v4.1-v4.4 features + precision tolerance + Euler ops
v4.1 收尾:
- IncrementalUpdateEngine: dirty flag propagation, cache invalidation
- LargeAssembly: InstanceCache, assembly instancing
- STEP import: robust/graceful parsing with skip tracking
v4.3 分析工具:
- Mass properties (volume, centroid, inertia tensor)
- Clearance analysis, wall thickness analysis
- Enhanced drawing: hidden-line removal, offset sections, BOM
- DXF import (LINE/CIRCLE/ARC/LWPOLYLINE/SPLINE → B-Rep extrusion)
v4.4 地基加固:
- ToleranceChain: RSS cumulative tolerance propagation (7 tests)
- Euler operations: MEV/KEV/MEF/KEF/KEMR/MEKR (20 tests)
- Replace hardcoded tolerances with ToleranceConfig in validate
- Fix incremental_update test API mismatch (15/15 pass on Linux)
Docs:
- v4.1-v4.4 development plans + roadmap updated
- v4.4 marked complete on Linux
