Ziel: einem interessierten Mathematiker ermöglichen, die bisherige Arbeit
unabhängig zu validieren und eigene Forschung beizutragen.
Neu:
doc/math/discrete-conformal-theory.md
Kompakte mathematische Einführung (DCE, Variationsprinzip, drei
Geometriemodi, Holonomie, Periodenmatrix) für Riemann-Flächen-Kenner.
doc/math/validation.md
Analytisch bekannte Sollwerte + wie man sie mit dem Code prüft:
Gauss–Bonnet (χ), τ ∈ Fundamentaldomäne (3 Invarianten), Symmetrie-
Argumente für τ=i (4-fach) und τ=e^{iπ/3} (6-fach), Newton-Konvergenz,
Gradienten-Check (FD), Holonomie-Kommutator. Reviewer-Checkliste.
CONTRIBUTING.md (Root)
Gitea/GitHub-Standard: CONTRIBUTING.md im Root-Verzeichnis als
Kurzreferenz mit Links zu doc/contributing.md und den Math-Docs.
code/data/off/torus_4x4.off — 16 Vertices, 32 Flächen, Genus 1
code/data/off/torus_8x8.off — 64 Vertices, 128 Flächen, Genus 1
code/data/off/torus_hex_6x6.off — 36 Vertices, 72 Flächen, 6-fach Sym.
Aktualisiert:
README.md — 158 → 170 Tests, zwei neue Math-Links in Tabelle
doc/api/tests.md — 28 Suiten, 170 Tests, 1 Skip (korrigiert)
doc/contributing.md — Testzähler 158+2 → 170+1

## Language
|
|
|
|
**All code, comments, documentation, commit messages, and test descriptions must be in English.**
|
|
|
|
The project targets CGAL submission and international collaboration. When editing
|
|
files that still contain German-language comments or documentation, replace them
|
|
with English.
|
|
|
|

|
|
|
|
## Git workflow
|
|
|
|
- `main` is protected on `origin` (Gitea). Push to `dev`, then open a pull request.
|
|
- `codeberg/main` can be pushed to directly (public mirror, no CI).
|
|
- Both remotes must stay in sync after every significant change:
|
|
```bash
|
|
git push origin HEAD:dev # triggers CI
|
|
git push codeberg main # updates public mirror
|
|
```
|
|
- Branch naming: `feature/<topic>`, `fix/<topic>`, `phase<N>-<topic>`
|
|
|

|
|
|
|
## CI
|
|
|
|
Two jobs run on push to `dev`/`main` or on pull requests:
|
|
|
|
| Job | What it tests | Trigger |
|
|
|---|---|---|
|
|
| `test-fast` | 36 non-CGAL tests, no Boost | all branches |
|
|
| `test-cgal` | 170 CGAL tests + 1 skip | `main`, `dev`, PRs only |
|
|
|
|
A PR is ready to merge when both jobs pass.
|
|
|
|
The runner is a self-hosted Raspberry Pi (ARM64). See `.gitea/workflows/cpp-tests.yml`
|
|
and `.gitea/docker/Dockerfile.ci-cpp`.
|
|

## Test standards
|
|
|
|
Every new algorithm needs:
|
|
|
|
1. **Gradient check** — finite-difference verification of `G(x) = ∂E/∂x`.
|
|
Copy any `GradientCheck_*` test suite from `tests/cgal/test_*_functional.cpp`.
|
|
|
|
2. **Convergence test** — Newton converges on a small mesh using the "natural theta"
|
|
trick (see [CLAUDE.md](../CLAUDE.md) and [api/extending.md](api/extending.md)).
|
|
|
|
3. **Registration** — add the `.cpp` file to `code/tests/cgal/CMakeLists.txt`.
|
|
|
|
Expected CI result: **36 + 170 tests pass, exactly 1 skipped**.
|
|
The skip is an intentional `GTEST_SKIP()` stub for the genus-2 homology test
|
|
(`cgal.HomologyGenerators.Genus2_FourGeneratorPaths_BLOCKED`) — blocked until a
|
|
genus-2 mesh is available in Phase 9c. Do not remove it.
|
|
|

|
|
|
|
## Code style
|
|
|
|
- C++17. Header-only (`code/include/*.hpp`). No compiled library.
|
|
- `#pragma once` at the top of every header.
|
|
- Everything in the `conformallab` namespace, internal helpers in `conformallab::detail`.
|
|
- Property map names follow the prefix convention: `"v:"` (vertex), `"e:"` (edge), `"f:"` (face).
|
|
- DOF index `-1` always means "pinned/fixed".
|

## Releases
|
|
|
|
Release tags follow `vMAJOR.MINOR.PATCH`:
|
|
|
|
```bash
|
|
# Merge dev → main, then tag
|
|
git checkout main && git merge --no-ff dev
|
|
git tag -a vX.Y.Z -m "vX.Y.Z — <one-line summary>"
|
|
git push origin main && git push origin vX.Y.Z
|
|
git push codeberg main && git push codeberg vX.Y.Z
|
|
```
