Audit found that 2 of the 4 Java-port candidates from the conformal-
mapping discussion were missing from the documentation:
* StereographicUnwrapper (266 Java LoC) — projects spherical layout
S² → ℂ via stereographic projection + Möbius centring. Closes the
visualisation gap from discrete_conformal_map_spherical() which
currently returns Point_3 on S²; downstream uses typically want a
2-D atlas. Suggested phase: 10b' (alternative methods, parallel
to Hyperbolic / Quasi-isothermic). Effort: small (~3 days).
* CircleDomainUnwrapper (570 Java LoC) — conformal map of a
multiply-connected planar region onto a disk-with-holes (Koebe's
general uniformization theorem 1909). A use-case class
conformallab++ does not currently cover (annulus, slit torus,
fluid flow around obstacles, electrostatics with multiple
conductors). Suggested phase: 11c. Effort: large (~2 weeks).
Added to all three roadmap documents:
* doc/roadmap/java-parity.md — worth-porting table extended
* doc/roadmap/research-track.md — Java-backlog summary extended
* doc/roadmap/phases.md — Phase 10b' bullet + new
Phase 11c block with full math
context (Koebe 1909 reference,
classical complex-analysis use cases).
