docs: learn from Parasolid — actionable boolean robustness improvements
CI / Build & Test (push) Failing after 1m31s
CI / Release Build (push) Failing after 31s
Build & Test / build-and-test (push) Has been cancelled
Build & Test / python-bindings (push) Has been cancelled
7-class degenerate taxonomy, multi-point sampling, tolerance ladder,
strategy fallback cascade. All immediately implementable.
Today: multi-point voting (~200 lines), PerFace tolerance (~100)
This week: 7 detection functions (~500), 3-level fallback (~500)

docs: global boolean algorithm survey — 5 categories, 9 improvements
CI / Build & Test (push) Failing after 29s
CI / Release Build (push) Failing after 33s
Build & Test / build-and-test (push) Has been cancelled
Build & Test / python-bindings (push) Has been cancelled
Covers: SSI (Parasolid), Classification (ACIS), Exact (CGAL/Cork),
BSP (Carve), Ray-cast (Manifold), SDF (OpenVDB), Octree
Key borrowings:
1. Parasolid 7-class degenerate taxonomy
2. ACIS multi-point voting
3. Manifold 2-manifold guarantee + sweep-line coplanar
4. OpenVDB adaptive voxel SDF preview
Immediate: integrate exact_predicates, multi-point voting
