doc/concepts/declarative-pipeline.md — vollständige Design-Spezifikation:
1. Kernidee: Processing Units mit expliziten require/provide-Contracts
2. Token-Vokabular: 30 Tokens in 7 Kategorien
input, setup, Gauss-Bonnet, solver, topology, layout, period/domain/output
3. YAML-Schema: Vollständige Syntax inkl. Parameterdefaults aller Units
4. Validierungsalgorithmus: monoton wachsendes provided-Set, Pre-Execution-Check
5. 5 vollständige Beispiele:
A — Euklidische Uniformisierung Torus (τ-Ausgabe)
B — Sphärische Uniformisierung (cathead.obj)
C — Hyperbolische Uniformisierung Torus (Poincaré-Disk)
D — Volle Pipeline mit Periodenmatrix + 5×5-Kachelung
E — Absichtlich fehlerhaftes Beispiel mit Validator-Fehlermeldungen
6. C++-Mapping: alle YAML-Unit-Namen → C++-Funktionen + Header
7. Implementierungsplan (Phase 8e): pipeline.hpp + CLI-App + YAML-Abhängigkeit
8. Design-Entscheidungen: YAML vs. JSON/TOML, explizit vs. auto-inference,
linear vs. DAG, eine Geometrie pro Datei
doc/api/cgal-package.md: Link zum Konzeptdokument ergänzt.
README.md: Link in Dokumentationstabelle ergänzt.

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

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

Root cause: -DWITH_CGAL=ON implied -DWITH_VIEWER=ON, which pulled in
GLFW, which requires wayland-scanner — not present in the headless CI
container (ubuntu:22.04 ARM64).
Fix: new CMake option -DWITH_CGAL_TESTS=ON builds conformallab_cgal_tests
without touching the viewer, GLFW, libigl, or any display dependency.
Only Boost headers are required (already in the Docker image).
Changes
───────
code/CMakeLists.txt
- Add WITH_CGAL_TESTS option (OFF by default)
- find_package(Boost REQUIRED) now shared between WITH_CGAL and WITH_CGAL_TESTS
- WITH_CGAL still implies WITH_VIEWER (for local full builds)
- Remove duplicate find_package(Boost) inside the WITH_CGAL block
code/tests/CMakeLists.txt
- cgal/ subdirectory added for WITH_CGAL OR WITH_CGAL_TESTS
.gitea/workflows/cpp-tests.yml
- test-cgal job: -DWITH_CGAL=ON → -DWITH_CGAL_TESTS=ON
README.md
- Build modes table: three rows (default / CGAL_TESTS / CGAL full)
- Quick-start: separate headless and full-local sections
- Prerequisite table updated

Structured the development roadmap into four blocks with an explicit
boundary marker separating direct Java ports (Phase 1–7) from
infrastructure (Phase 8), remaining porting (Phase 9), and new
research territory (Phase 10+).

Mark all Phase 3 sub-phases (3a–3g) as done in the roadmap.
Add euclidean_hessian and spherical_hessian to the feature table.
Update status banner: 62 tests, Phase 4 is next.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Six concrete next steps toward Phase 3 completion and Phase 4 (solver):
3d EuclideanCyclicFunctional — most critical missing functional
3e Spherical gauge-fix (1D Brent along additive u constant)
3f Analytic Hessian via CGAL::Weights::cotangent_weight()
3g Consolidate duplicate PI constant
4a Minimal Newton solver with Eigen SimplicialLDLT
4b CGAL::IO read/write OBJ for mesh round-trip testing
