Add bit-for-bit (1e-12) golden-value oracle tests pinning the C++ pure-math
and functional cores against the compiled upstream Java library (openjdk 17):
- HyperIdealGoldenJava: Clausen/Л/ImLi2, ζ13/14/15/ζ, both tetrahedron-volume
formulas (real de.varylab…Clausen / HyperIdealUtility).
- EuclideanGoldenJava / SphericalGoldenJava: angle formulas + β relations + Л
energy terms, plus FULL-MESH oracles driving the real EuclideanCyclicFunctional
/ SphericalFunctional on a shared tetrahedron — per-vertex gradient (Θ−Σα) and
ΔE = E(x)−E(0) (C++ Gauss-Legendre path integral vs Java closed form).
- SphericalGoldenJava.FullMeshEdgeDofGradient: edge-DOF gradient (vertex + edge
components, α_opp⁺+α_opp⁻−θ_e) vs raw conformalEnergyAndGradient — locks
Finding 3 at the solution level (audit items 4 & 5).
- PeriodMatrix.NormalizeModulus_GoldenJava: τ-reduction fold convention vs the
real DiscreteEllipticUtility.normalizeModulus (audit items 7 & 8).
Subtlety documented: the spherical oracles call Java's raw
conformalEnergyAndGradient, not evaluate() (which pre-runs a Brent gauge
maximization that C++ factors into the Newton solver's spherical_gauge_shift).
Also:
- P1-2 (layout.hpp): Euclidean holonomy now uses a per-cut-edge rigid-motion fit
g(z)=a·z+b, exposing residual_rotation = |arg(a)| as a diagnostic; non-
regressive (flat case a=1 reduces to the old midpoint formula).
- P1-3 (period_matrix.hpp): is_in_fundamental_domain fixed to the correct
half-open SL(2,ℤ) domain (−½ ≤ Re < ½). Updated the now-exposed
ComputePeriodMatrix_ReducedTau_InFD to assert the normalizeModulus domain
(closed +½ edge) instead.
Test counts (single source of truth = doc/api/tests.md): 272/272 pass, 0
skipped (26 non-CGAL + 246 CGAL).

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.

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.
