This commit closes the structural-tests work on PR #18. Every gate
in `run-all.sh --fast` now passes end-to-end on the canonical dev
machine.
New gates
─────────
1. shellcheck (scripts/quality/shellcheck.sh)
* Scans every `scripts/**/*.sh` at severity=warning+
* 16 scripts inspected; cleanup pass took the tree from 7 findings
(SC2164 + SC2034) to 0 findings.
2. cppcheck (scripts/quality/cppcheck.sh)
* Complementary static analyser to clang-tidy; different heuristics,
fewer false-positives on heavy CGAL/Eigen templates.
* Default severity warning+, --strict adds style, --all = everything.
* Suppresses 4 noise classes (missingIncludeSystem, etc.) explicitly.
3. .editorconfig
* Cross-IDE fallback for editors that don't honour clang-format.
* Covers Markdown (preserve trailing whitespace), Python, YAML,
JSON, shell, Makefile (tabs) — the file types clang-format
doesn't cover.
4. CONFORMALLAB_WARNINGS_AS_ERRORS CMake option
* Off by default → regular builds don't break on new GCC warnings.
* `-DCONFORMALLAB_WARNINGS_AS_ERRORS=ON` adds `-Werror`, intended for
CI promotion-track and sanitizer runs.
Dependency audit (doc/architecture/dependencies.md)
────────────────────────────────────────────────────
New single-source-of-truth document listing:
* what the library requires (Eigen + CGAL + Boost — all header-only)
* what tests require (auto-fetched GTest, no system install)
* what each quality tool is for, install command per OS, and
behaviour when missing (each gate exits 2 = SKIP, run-all
recognises this and continues)
* a verification recipe that strips PATH down and shows the
library still configures + builds + tests cleanly with zero
quality tools installed.
run-all.sh enhanced
───────────────────
* Recognises "tool not in PATH" → SKIP (not FAIL).
* Summary now reports `passed / skipped / failed` separately.
Bug fixes uncovered by the sweep
────────────────────────────────
* sanitizers.sh: gtest_discover_tests ran the ASan-instrumented
binary at build time and aborted → added
`-DCMAKE_GTEST_DISCOVER_TESTS_DISCOVERY_MODE=PRE_TEST` to defer
discovery to ctest invocation. Now 23/23 sanitizer-instrumented
tests pass.
* clang-tidy.sh on macOS: brew-installed clang-tidy couldn't find
Apple SDK system headers (<cmath>, <complex>, …) → added
`--extra-arg=-isysroot $(xcrun --show-sdk-path)` on Darwin.
* clang-tidy.sh: needed `-DWITH_CGAL_TESTS=ON` in compile_commands
generation so CGAL include paths are part of at least one
compile entry. Now resolves CGAL/Surface_mesh.h etc.
* clang-tidy.sh: viewer-only headers (`viewer_utils.h`, `mesh_utils.hpp`)
excluded — they need `WITH_VIEWER=ON` + system GLFW/libigl that the
lint build doesn't drag in.
* `.codespellrc`: extended ignore list (recognise, signalled, modelled,
travelled, …) for British-English consistency across own writing.
Final state — local quality block on this commit, this branch:
✅ License headers (66/66 carry MIT SPDX)
✅ CGAL conventions (0/6 violations on 6 CGAL headers)
✅ clang-format drift (0 drift)
✅ cmake-format/-lint (0 drift, 0 lint findings)
✅ codespell (0 typos in scope)
✅ shellcheck (0 findings across 16 .sh files)
✅ cppcheck (warning+ severity clean)
✅ Markdown links (122/122 resolve)
✅ Sanitizers (ASan+UBSan) (23/23 fast tests pass)
✅ clang-tidy (35 headers inspected, 0 findings)
Library standalone-ness verified:
env -i PATH=... cmake -S code -B /tmp/build-standalone
cmake --build /tmp/build-standalone --target conformallab_tests
ctest -E '^cgal\.' → all green

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

CGAL 6.x still unconditionally includes boost/config.hpp in its
config.h, so Boost headers are required even with CGAL_DISABLE_GMP/MPFR.
Use system Boost via find_package instead of the removed 211 MB tarball.
Tests-only mode remains completely dependency-free.
Install: brew install boost (macOS)
apt install libboost-dev (Debian/Ubuntu)

Restructures the CMake build into three clearly separated modes:
(default) tests only – Eigen + GTest, no heavy deps
-DWITH_VIEWER=ON builds viewer lib (libigl / GLFW / GLAD)
-DWITH_CGAL=ON builds conformallab_core CLI app;
implies WITH_VIEWER automatically
Changes:
- code/CMakeLists.txt: viewer and core targets are now guarded by
option() flags; GTest / tests target is always built
- code/deps/Cmakelists.txt: CGAL, libigl, glfw, glad are only
extracted when the corresponding mode is enabled; Eigen always
- Remove Boost (211 MB tarball, 0 usages in the codebase – CGAL 6.x
does not require Boost for Simple_cartesian / Surface_mesh / basic IO)
- Remove code/src/main.cpp (dead file, not referenced in CMake)
All 16 C++ tests pass in tests-only mode (verified locally).

- Add Google Test via CMake FetchContent (v1.14.0)
- Add clausen.hpp: Clausen integral, Lobachevsky function, Im(Li2)
- Add hyper_ideal_utility.hpp: generalized and ideal-vertex hyperbolic
tetrahedron volume formulas using Eigen for the 4x4 Gram determinant
- Port ClausenTest (5 tests) and HyperIdealUtilityTest (8 tests) from
Java/JUnit — all 13 pass with same tolerances as the Java originals
- Fix pre-existing VIEWER/viewer case mismatch in CMakeLists.txt
