Phase 4 complete — 87 CGAL tests pass, 2 skipped. Newton solver (phase4a): - hyper_ideal_hessian.hpp: symmetric FD Hessian (O(ε²), PSD by convexity) - newton_hyper_ideal(): Newton + backtracking for the HyperIdeal functional - detail::solve_with_fallback(): optional bool* fallback_used parameter - solve_linear_system(): public API exposing LDLT→SparseQR fallback SparseQR fallback tests (SparseQRFallback.*): - FullRankSystem_CorrectSolution: LDLT path, fallback_used=false - SingularMatrix_FallbackActivated: zero-pivot → QR activated, fallback_used=true - Euclidean_ClosedMeshNoPinConverges: gauge-mode null space handled via QR HyperIdeal Newton tests (NewtonSolver.HyperIdeal_*): - ConvergesTriangleAllVariable, ResultFieldsConsistent, ConvergesTetrahedron, SparseQRFallbackNoCrash - Natural-target base point (b=1.0, a=0.5) — x=0 is degenerate in log-space Pipeline tests (test_pipeline.cpp): - End-to-end: all three geometries, mesh I/O round-trip, solve+export Example programs (code/examples/): - example_euclidean.cpp: headless Euclidean pipeline - example_hyper_ideal.cpp: headless HyperIdeal pipeline - example_viewer.cpp: interactive libigl viewer with jet colour map README: - Mathematical scope table: C++ vs Java original (18 rows) - "For mathematicians" section: mental model, step-by-step new-functional guide, half-edge traversal snippets, recommended reading Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
