docs: note high-precision requirement for Phase 9c/10 uniformization
Some checks failed

The Java uniformization classes (FundamentalPolygonUtility, CanonicalFormUtility) rely on the *Big arbitrary-precision geometry (MathContext(50)) because products of hyperbolic isometry generators grow exponentially and double fails to verify the group relation ∏gᵢ = Id. Record this planning-relevant prerequisite and resolve the contradiction in java-parity.md, which previously listed *Big as permanently out of scope. - CLAUDE.md: † note on the Phase-9 not-yet-ported table - java-parity.md: *Big exception (localized high-precision substrate for 9c/10) - phases.md: precision prerequisite as 9c sub-task + effort estimate - design-decisions.md: new "Scalar type: double, with one localized exception" Core flattening (Newton/energy/Eigen solver) stays double; the substrate (cpp_dec_float_50 / mpreal) is localized to the uniformization module only.

Cross-referenced all 232 Java classes against the roadmap. New plan entries for genuinely-useful, previously-unplanned items: - 9g.1 conformal quality measures (Isothermicity, ConformalEquivalence, FlippedTriangles, LengthCrossRatio + ConvergenceUtility metrics) - 9g.2 optional period-matrix convergence experiment (method only; Java harness depends on Mathematica/JLink + jReality, not ported) - DEC operator layer (heds/dec/) noted as a 10a prerequisite - HomotopyUtility -> 10a (explicit generator cycles; not covered by cut_graph.hpp, which yields only the 2g cut edges) - SurfaceCurveUtility -> 9c; MercatorTextureProjection -> 9d.3 companion Documented as deliberately out-of-scope: SpanningTreeUtility (subsumed by cut_graph.hpp), convergence/* harness, datasource/* (jReality viewer decoration), *Big arbitrary-precision geometry, jReality GUI, and the MTJ/Tao/PETSc solver bindings.

docs: fix cherry-pick duplicate 9d/9e sections — merge into unified structure
Auto-merge from cherry-pick concatenated both branch versions of Phase 9d
and 9e. This commit resolves the duplication:
- 9d now has 4 sub-items (9d.1–9d.4) combining both branches:
9d.1 ConesUtility (detailed: BFS, auto-placement, quantization)
+ Troyanov/Springborn refs (from literature analysis)
9d.2 Non-Euclidean cone extensions (RESEARCH)
+ Bobenko-Lutz 2025 + Crane 2018 (from literature analysis)
9d.3 StereographicUnwrapper + SphereUtility
9d.4 MobiusCenteringFunctional
- 9e keeps the detailed reviewer/meeting-prep version
+ adds mathematical references (Bobenko-Hoffmann-Springborn 2006)
- 9f (Polygon Laplacian, Alexa 2011/2020) retained as standalone section

docs: add StereographicUnwrapper + CircleDomainUnwrapper to roadmap
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).

Phase 9a-Newton: newton_cp_euclidean + newton_inversive_distance
Some checks failed
C++ Tests / test-fast (push) Has been cancelled
C++ Tests / test-cgal (push) Has been cancelled
C++ Tests / test-fast (pull_request) Successful in 2m28s
API Docs / doc-build (pull_request) Successful in 52s
C++ Tests / test-cgal (pull_request) Failing after 11m29s
Wires the two Phase-9a functionals into the Newton-solver layer so
they are operational end-to-end. CGAL test count: 212 → 219 (+7).
Solvers
───────
* newton_cp_euclidean(mesh, x0, m, tol, max_iter)
- Uses cp_euclidean_hessian — analytic 2×2-per-edge BPS-2010
formula h_jk = sin θ / (cosh Δρ − cos θ).
- SparseQR fallback handles the gauge-singular case when no face
is pinned (caller error, but we recover gracefully).
- Strictly-convex energy ⇒ quadratic convergence near optimum.
* newton_inversive_distance(mesh, x0, m, tol, max_iter, hess_eps)
- Uses an inline FD Hessian (n × gradient evaluations per step) —
mirrors the Phase 4a HyperIdeal solver in spirit.
- Analytic alternative via Glickenstein 2011 eq. (4.6) is tracked
in doc/roadmap/research-track.md as Phase 9a.2-analytic.
- Sensitive to initial point; the test suite always starts from
a natural-theta setup (u = 0 is the equilibrium when
compute_inversive_distance_init_from_mesh was called).
Tests (test_newton_phase9a.cpp, 7 cases)
────────────────────────────────────────
* CPEuclidean_NaturalPhi_ClosedTetrahedron_ConvergesInZeroIterations
* CPEuclidean_PerturbedStart_ConvergesBackToEquilibrium
* CPEuclidean_OpenTetrahedron_NaturalPhi_Converges
* InversiveDistance_NaturalTheta_Triangle_ConvergesInZero
* InversiveDistance_PerturbedQuadStrip_Converges
* InversiveDistance_PerturbedTetrahedron_Converges
* CPEuclidean_UsesAnalyticHessian
Regression guard: 3-DOF problem converges in ≤ 10 iterations even
with strong perturbation, confirming the analytic Hessian path is
actually used.
All seven tests pass. Full CGAL suite: 219/219 PASSED, 0 SKIPPED.
Roadmap additions (`doc/roadmap/phases.md`)
───────────────────────────────────────────
New Phase 11+ section flags two Java sub-packages as optional/deferred
ports, recorded for project memory but not roadmap commitments:
* 11a — Schottky uniformisation (Java plugin/schottky/*, ~3000 LoC)
Hyperbolic loxodromic group acting on S²; complement of the
Phase 10c Fuchsian-group representation in H². Requires
Phase 10b period matrix + Möbius-group machinery from Phase 7.
Effort: very large (4-6 weeks).
* 11b — Riemann maps (Java plugin/riemannmap/*, ~1500 LoC)
Discrete Riemann mapping theorem; texture mapping of bounded
planar regions, classical conformal mapping for engineering.
Requires Phase 10b' quasi-isothermic or Phase 9a.1 CP-Euclidean.
Effort: large (3-4 weeks).
Both are explicitly NOT roadmap commitments — they live in the doc so
they aren't re-discovered.

docs: full audit — fix 4 wrong port/research labels + consolidated research-track
Some checks failed
C++ Tests / test-fast (push) Successful in 2m50s
C++ Tests / test-fast (pull_request) Successful in 2m36s
API Docs / doc-build (pull_request) Successful in 1m10s
C++ Tests / test-cgal (push) Has been skipped
C++ Tests / test-cgal (pull_request) Failing after 10m25s
A full audit of `doc/` plus root-level markdown files (27 files) against
the actual ground truth in the C++ code and the local Java repository at
`/Users/tarikmoussa/Desktop/conformallab/` revealed four pre-existing
mis-labels and a stale test count. All are corrected here.
Audit findings — corrected
─────────────────────────
1. **`InversiveDistanceFunctional` mis-labelled as Java port** (4 doc sites)
Empirical verification:
find /Users/tarikmoussa/Desktop/conformallab -iname "*nversive*"
(zero matches)
The class does NOT exist in `de.varylab.discreteconformal`. The C++
implementation is built from Luo 2004 + Glickenstein 2011 + Bowers-
Stephenson 2004 — new research, not a port.
Fixed in: java-parity.md, references.md, add-inversive-distance.md.
2. **HyperIdeal Hessian mis-labelled as "Java has analytic Hessian"**
Empirical verification: `HyperIdealFunctional.java:295-298`:
public boolean hasHessian() { return false; }
Java has NO Hessian at all. Both the FD (Phase 4a) and the block-FD
(Phase 9b) Hessians in C++ are research beyond the Java port. The
chain rule (b,a) → ℓ → ζ → α/β is the *mathematical formulation*
from Springborn 2020, not something Java implements.
Fixed in: java-parity.md.
3. **Stale test count** README:87 said "28 suites, 170 tests" — current
actual is 35 suites, 176 CGAL + 36 non-CGAL. Fixed.
4. **Tutorial framing** — `add-inversive-distance.md` was framed as
"porting an InversiveDistanceFunctional.java" that does not exist.
Rewritten as "Implementing the Inversive-Distance functional from
Luo 2004" with prominent verification block at top.
New document: `doc/roadmap/research-track.md`
─────────────────────────────────────────────
Consolidates everything in conformallab++ that goes beyond a Java port:
* Items already on `main`: HyperIdeal FD Hessian, period matrix τ
partial-research components, Möbius holonomy storage.
* Items on open PRs: CP-Euclidean (PR #8, port), Inversive-Distance
(PR #8, research), block-FD Hessian (PR #9, research).
* Planned research with full citations:
- **Phase 9b-analytic** — full analytic HyperIdeal Hessian via
Schläfli identity (Schläfli 1858/60) and chain rule through
ζ₁₃/ζ₁₄/ζ₁₅, citing Springborn 2020 §4, Cho-Kim 1999,
Glickenstein 2011 §4. Includes acceptance-criteria checklist
(per-case derivative cross-checks, gauge null space, PSD,
measured ≥ 3× speed-up, LaTeX correctness note).
- **Phase 9a.2-analytic** — analytic inversive-distance Hessian
via Glickenstein 2011 eq. (4.6).
- **Phase 10c** — full uniformization for genus g ≥ 2 (Fuchsian
group representation) — fully new research, no Java reference.
- **geometry-central** GC-1/2/3 exploratory track.
* Java backlog summary: 11 worth-porting Java classes identified by
the parallel survey (FundamentalPolygonUtility, DiscreteHarmonicForm-
Utility, DiscreteHolomorphicFormUtility, CanonicalBasisUtility,
HyperbolicCyclicFunctional, QuasiisothermicUtility, KoebePolyhedron, …).
~6 500 Java lines, ~5 months of porting work, organised by phase.
Updated documents
─────────────────
* CLAUDE.md
- New "Port-vs-research maintenance rule" with empirical verification
command and the four corrected mis-labels.
- Doc map: 23 → 24 documents (research-track.md added).
* README.md
- Test count corrected (170 → 176+36).
* doc/math/references.md
- Luo 2004 entry corrected ("new research" instead of "not yet ported").
- New entries for Bowers-Stephenson 2004, Glickenstein 2011,
Bobenko-Pinkall-Springborn 2010, Schläfli 1858/60.
* doc/roadmap/phases.md
- Phase 9 reorganised: 9a split into 9a.1 (port) / 9a.2 (research),
9b clarified as research (Java has no Hessian), 9c expanded with
Java line counts and effort estimates.
- Phase 10 reorganised: 10a/10b/10c with their Java prerequisites
explicitly listed; 10c flagged as "fully new research".
- Phase 10b' added: parallel research track (hyperbolic functional,
quasi-isothermic, Möbius centering).
- Phase 10c' added: optional Java-port additions (Koebe, circle
patterns, electrostatic sphere).
* doc/roadmap/java-parity.md
- Inversive-distance row: ❌ Java, ❌ C++ (Phase 9a.2) — new research.
- CP-Euclidean row added: ✅ Java, ❌ C++ (Phase 9a.1) — port.
- HyperIdeal Hessian row: ❌ Java, ⚠️ FD + block-FD in C++.
- Worth-porting table replaced with the survey results (12 classes,
Java line counts, suggested phases).
- "HyperIdeal Hessian: FD vs analytic" section rewritten with the
correction notice.
* doc/tutorials/add-inversive-distance.md
- Rewritten end-to-end with prominent verification block at top.
- Now correctly framed as "Implementing the Inversive-Distance
functional from Luo 2004" — research, not port.
- Includes the four required cross-validations:
limit cases, Bowers-Stephenson round-trip, FD-vs-analytic,
cross-validation against euclidean_functional at u=0.
- New "How to know if it's a port or research" closing section
with the empirical verification command.
