Re-evaluated cost/benefit of Phase 8 vs Phase 9 after distinguishing three
concurrent goals:
• Goal A (Port): ~90% done, ~3 weeks remaining
• Goal B (CGAL): speculative, 12+ months, uncertain submission
• Goal C (Tool): research utility with novel features
Phase 8 full (3–4 weeks) would mostly serve Goal C plus optional Goal B.
Phase 9 (3 weeks) finishes Goal A unconditionally. Building Phase 8 in
full before Phase 9 risks 3-4 weeks of speculative architecture for a
hypothetical CGAL submission.
New strategy: Hybrid MVP.
Phase 8 MVP (3–5 days):
Conformal_map_traits.h concept + Default<Surface_mesh,K>
Discrete_conformal_map.h ONE entry: _euclidean()
4 named parameters Theta-map, max_iter, tol, pin
Concept-check header + Doxygen
Phase 9a (3–5 days): Inversive-Distance vs MVP API = acceptance test
Phase 9b + 9c (~2 weeks): Port truly complete
Phase 8 extensions: Only on concrete trigger
8a.2 generic FaceGraph trigger: Polyhedron_3 user
8c full doc trigger: submission planned
8d CGAL-format tests trigger: submission planned
8e YAML pipeline orthogonal, any time
Net committed budget: ~4 weeks for "port complete + CGAL MVP",
not 6–8 weeks for full Phase 8 + Phase 9.
