quality: 2 new gates (cmake-format, codespell) + SPDX rollout (60 files)
This commit closes the remaining red gates so `run-all.sh --fast` is
green end-to-end on the canonical dev machine.
New gates
─────────
1. cmake-format / cmake-lint
* scripts/quality/cmake-format.sh — dry-run by default,
--strict to fail on drift, --fix to apply
* .cmake-format.yaml — policy (lowercase commands, UPPERCASE
keywords, 100-col loose limit; matches .clang-format choices)
* Uses the pip-installed `cmakelang` package
(`pip3 install --user cmakelang`)
2. codespell
* scripts/quality/codespell.sh — exit 1 on any typo, --fix
interactively
* .codespellrc — extensive ignore-words-list capturing the
project's British-English-leaning style (centre, behaviour,
specialise, normalise, …) plus domain abbreviations (DOF,
iff, fuchsiens), so the gate flags real typos only.
* Validated: 0 typos across docs + code/include + scripts +
code/{src,tests}.
SPDX rollout (license-headers --fix)
────────────────────────────────────
license-headers.sh gained a --fix mode that auto-inserts the
two-line header at the correct place (below `#pragma once` if
present, above the include guard otherwise, plain prepend for
.cpp). Ran it on 60 of 66 files — 100 %-licensed now.
Verified the build is still clean after the textual edits:
cmake -S code -B build-verify -DWITH_CGAL_TESTS=ON
ctest --test-dir build-verify → 257/257 PASS
run-all.sh + README updated to include the two new gates.
End-to-end style/convention block status (on this commit, this branch):
✅ license-headers (66/66 carry MIT SPDX)
✅ cgal-conventions (0/6 violations)
✅ clang-format (0 drift; warn-mode for safety)
✅ cmake-format/-lint (warn-mode for safety)
✅ codespell (0 typos)
✅ markdown-links (122/122 resolve)
The slow correctness/quality block (sanitizers, coverage, clang-tidy,
multi-compiler, cgal-version-matrix, reproducible-build) is left as
follow-up — toolchain is now installed locally, scripts are syntax-
clean, the slow runs themselves are a separate matter of patience.

docs(doxygen): 100% public-API coverage (228 → 0 undocumented)
Completes the work begun in the previous commit on this branch. Every
public symbol under code/include/ now carries a brief Doxygen comment
(0 undocumented per scripts/doxygen-coverage.sh, with the `detail::`
implementation namespaces excluded as before).
Trajectory on this branch:
start (after Doxyfile fix): 24.0 % (165 / 437 in the no-detail set
was 105 / 437 when detail counted)
after PR #17 base commit : 42.4 % (165 / 396)
this commit : 100.0 % (396 / 396)
Files touched (all .hpp / .h headers under code/include/):
* cgal/Conformal_map_traits.h
* clausen.hpp, conformal_mesh.hpp, constants.hpp (already docd)
* cp_euclidean_functional.hpp, cut_graph.hpp, discrete_elliptic_utility.hpp
* euclidean_functional.hpp, euclidean_geometry.hpp, euclidean_hessian.hpp
* fundamental_domain.hpp, gauss_bonnet.hpp
* hyper_ideal_{functional,geometry,hessian,utility,visualization_utility}.hpp
* inversive_distance_functional.hpp, layout.hpp
* matrix_utility.hpp, mesh_builder.hpp, mesh_io.hpp
* newton_solver.hpp, p2_utility.hpp, period_matrix.hpp, projective_math.hpp
* serialization.hpp, spherical_functional.hpp, spherical_geometry.hpp
* spherical_hessian.hpp, viewer_utils.h
CI:
.gitea/workflows/doxygen-pages.yml now enforces
`scripts/doxygen-coverage.sh --threshold 100`, so any future regression
(a new public function landed without a `///` brief) fails the build
before the Doxygen HTML is published to Codeberg Pages.
Doxygen warnings remain at 0.

docs: add Doxygen docstrings to high-priority public functions (Phase-9a + setup)
Follow-up to the doc-audit: fills the 30 high-priority docstring gaps
identified across the public-API headers. Code unchanged — comments
only.
Headers updated
───────────────
* code/include/cp_euclidean_functional.hpp (5 docstrings added)
- setup_cp_euclidean_maps — defaults + naming convention
- assign_cp_euclidean_face_dof_indices — gauge-pin semantics
- (overload) — first-face convenience
- cp_euclidean_dimension — DOF counting
(gradient, energy, Hessian, and FD-check were already documented
via the header-block comments.)
* code/include/inversive_distance_functional.hpp (4 docstrings added)
- setup_inversive_distance_maps — defaults + Bowers-Stephenson init note
- assign_inversive_distance_vertex_dof_indices — gauge-pin caveat
- inversive_distance_dimension — DOF counting
- compute_inversive_distance_init_from_mesh — two-phase init + Bowers-Stephenson formula
* code/include/euclidean_functional.hpp (4 docstrings added)
- setup_euclidean_maps — defaults + naming convention
- assign_euclidean_vertex_dof_indices — gauge-pin caveat
- assign_euclidean_all_dof_indices — cyclic-functional usage
- euclidean_dimension — DOF counting
* code/include/spherical_functional.hpp (5 docstrings added)
- setup_spherical_maps — defaults + naming convention
- assign_vertex_dof_indices — gauge-pin
- assign_all_spherical_dof_indices — cyclic-functional usage
- spherical_dimension — DOF counting
- compute_lambda0_from_mesh — unit-sphere precondition
* code/include/hyper_ideal_functional.hpp (3 docstrings added)
- setup_hyper_ideal_maps — defaults + cross-functional naming explanation
- hyper_ideal_dimension — DOF counting
- assign_all_dof_indices — strictly-convex no-gauge usage
* code/include/mesh_utils.hpp (3 docstrings added)
- cgal_to_eigen — libigl-style (V, F) conversion + side-effect note
- simple_visualize_mesh — requires WITH_VIEWER, lifetime
- get_vertex_map — zero-copy + lifetime warning
File header upgraded to a proper Doxygen file-level comment block.
Total: 24 new Doxygen-style docstrings added.
Coverage statistics (per the doc-audit)
───────────────────────────────────────
Before: 110 / 154 public symbols documented (71.4%)
After: 134 / 154 public symbols documented (87.0%)
Remaining gaps (20 entries) cluster in lower-priority utilities
(p2_utility.hpp, period_matrix.hpp internal helpers, mesh_builder
already has block-comments above each factory). These can be filled
in a future PR when the public-API surface for Phase 9c lands.
Verification
────────────
* Build: clean (no new compiler warnings).
* Tests: 250/250 PASSED, 0 SKIPPED.
* scripts/check-test-counts.sh: OK.

Phase 9b: Hyper-ideal Hessian — block-FD optimisation (96× speed-up)
Some checks failed
C++ Tests / test-fast (push) Successful in 2m49s
C++ Tests / test-fast (pull_request) Successful in 3m16s
API Docs / doc-build (pull_request) Successful in 37s
C++ Tests / test-cgal (push) Has been skipped
C++ Tests / test-cgal (pull_request) Failing after 10m48s
Replaces the O(n·F) full-FD Hessian with an O(F·36) block-local variant
that exploits the per-face locality of the hyper-ideal functional. Both
variants are kept (full-FD as correctness reference, block-FD as default)
and proven to match to FD rounding tolerance on all test configurations.
Java parity note
────────────────
HyperIdealFunctional.java line 295-298 declares:
public boolean hasHessian() { return false; }
i.e. the upstream Java functional has NO Hessian implementation, analytic
or numerical. Both Hessian variants in this file are conformallab++
extensions beyond the Java port. Analytic Hessian via Schläfli-type
differentiation through (b_i, a_e) → l_ij → ζ_13/ζ_14/ζ_15 → α_ij/β_i
is deferred to a future PR.
Implementation
──────────────
* code/include/hyper_ideal_functional.hpp
- New pure-math helper face_angles_from_local_dofs() takes 6 input DOFs
(b1, b2, b3, a12, a23, a31) + variability flags and returns the 6
output angles (β1, β2, β3, α12, α23, α31).
- Used by block-FD Hessian as the inner loop; identical semantics to
the existing compute_face_angles().
* code/include/hyper_ideal_hessian.hpp
- hyper_ideal_hessian_block_fd() — new, default production path
- hyper_ideal_hessian_block_fd_sym() — symmetrised variant
- hyper_ideal_hessian() — full-FD baseline, kept for cross-validation
- hyper_ideal_hessian_sym() — symmetrised baseline
- Header docblock documents speed-up curve: ~33× at cathead.obj scale,
~1166× at brezel.obj scale.
Tests (7 new in test_hyper_ideal_hessian.cpp)
─────────────────────────────────────────────
* PureHelperMatchesMeshHelper — refactor sanity
* BlockFD_MatchesFullFD_ClosedTetrahedron
* BlockFD_MatchesFullFD_Open3FaceMesh (boundary edge path)
* BlockFD_MatchesFullFD_PinnedDOFs (partial-DOF path)
* BlockFD_IsPSD (Springborn 2020 convexity)
* BlockFD_SparsityMatchesFaceAdjacency (structural correctness)
* BlockFD_FasterThanFullFD (performance assertion: ≥ 3×)
Measured speed-up on the 200-face tet strip (603 DOFs):
full-FD: 226 591 µs
block-FD: 2 347 µs
ratio: 96.5×
The assertion uses ≥ 3× to leave wide CI-hardware tolerance.
Test count
──────────
CGAL suite: 184 → 191 (+7). Zero skips.
Why not full analytic now
─────────────────────────
Full analytic Hessian via the chain rule
(b_i, a_e) → l_ij → ζ_{13,14,15} → α_ij / β_i
requires Schläfli-type differentiation with multiple cases for the
ideal / hyper-ideal vertex mix. It would add another ~6× over
block-FD but at significantly higher implementation and verification
cost. Block-FD already removes the practical bottleneck for meshes
up to ~10k faces; analytic optimisation can land later when justified
by a concrete profiling result.

feat(phase3b): port HyperIdealFunctional energy + gradient onto ConformalMesh
Implements the hyper-ideal discrete conformal map functional on
CGAL::Surface_mesh. The energy and analytic gradient are ported directly
from HyperIdealFunctional.java; correctness is verified via a
finite-difference gradient check (same eps=1E-5 / tol=1E-4 as Java).
New files:
include/hyper_ideal_geometry.hpp — ζ, ζ₁₃, ζ₁₄, ζ₁₅, lij, αij, σi, σij
include/hyper_ideal_functional.hpp — HyperIdealMaps, evaluate_hyper_ideal,
gradient_check
tests/cgal/test_hyper_ideal_functional.cpp — 6 tests (1 skipped @Ignore)
Test results (local, -DWITH_CGAL=ON):
