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.

chore: translate all German text to English across code, docs, and CI
Unified the codebase language to English throughout. German text appeared in code comments, test file headers, CI step names, and several markdown documents. All natural-language text is now English; proper nouns (Institut für Mathematik, Technische Universität Berlin) are unchanged. Files changed: - .gitea/workflows/cpp-tests.yml — CI step names and job comments - code/include/mesh_utils.hpp — inline comment - code/tests/cgal/CMakeLists.txt — section comment block - code/tests/cgal/test_geometry_utils.cpp — full file header + all test comments - doc/math/references.md — geometry-central section - doc/math/validation.md — Section 9 (geometry-central cross-validation) - doc/roadmap/phases.md — Optional geometry-central track (GC-1/2/3) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |

docs: geometry-central Vergleich als optionalen Track einarbeiten
- phases.md: neue Sektion "Optional/Hypothetisch — geometry-central Cross-Comparison" mit GC-1 (Output-Vergleich, sofort möglich), GC-2 (Intrinsic Delaunay Pre-Conditioning, nach Phase 8) und GC-3 (Ptolemäischer Flip-Solver, hypothetisch Phase 10+) - validation.md: neuer Abschnitt 9 mit Vergleichstabelle, Normalisierungs- abgleich, Zeitplan und Springborn-2020-Einordnung - references.md: Gillespie–Springborn–Crane SIGGRAPH 2021 + Sharp 2019 als geometry-central-Referenzen eingetragen; Klarstellung zu Springborn 2020 - validation.md: Testzähler 170→173 / 11 skips→1 skip korrigiert Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |

docs: restructure documentation into focused files
README.md: reduced from 703 to ~75 lines — what/why, status, quick start, minimal usage example, navigation table to doc/ files. doc/architecture/overall_pipeline.md: trimmed — roadmap, extension points, declarative pipeline YAML, and references sections removed (each now has its own dedicated file). Replaced with a link table. New files: doc/getting-started.md — build modes, single-test invocation, CLI doc/api/pipeline.md — full pipeline API with code for all 3 geometries doc/api/extending.md — new functionals, geometry modes, Java porting guide doc/api/contracts.md — processing unit preconditions/provides table doc/api/cgal-package.md — Phase 8 CGAL package design + YAML pipeline (TODO) doc/math/geometry-modes.md — Euclidean/Spherical/HyperIdeal comparison doc/math/references.md — all papers by module doc/roadmap/phases.md — Phases 1–10 with porting/research boundary doc/roadmap/java-parity.md — Java vs C++ feature parity table doc/contributing.md — language policy, test standards, release flow Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |
