C2: Fix coverage.sh — remove || true from lcov capture/extract steps so real
lcov failures are visible; empty coverage.info now exits with code 3.
C3: Add coverage gate to quality-gates CI job (SKIP_COVERAGE_GATE=1 ramp-up
mode until I5 is resolved — fast suite covers ~9.6% not 80%). Thresholds:
80% line / 70% branch / 90% function (agreed 2026-05-31).
V1: Wrap JSON parse + field extraction in try/catch — nlohmann parse_error and
type_error now surface as std::runtime_error with the file path.
V2: Wrap stoi/stod in XML Solver parser — missing/non-numeric attributes throw
std::runtime_error instead of leaking std::invalid_argument.
V4: Validate required JSON keys (dof_vector, solver, solver.*) before access —
missing field produces a clear named-field error message.
I2: 6 serialization negative tests (missing file, malformed JSON, missing
dof_vector, missing solver block, missing XML file, non-numeric XML attr).
I3: load_mesh throws on non-triangulated (quad) mesh — covers the
is_triangle_mesh guard that was previously untested.
I4: spherical_hessian throws on edge DOFs — covers the logic_error guard.
290/290 tests pass (+8 new).

B1 (api-performance): wire hyper_ideal_hessian_block_fd_sym into newton_hyper_ideal
instead of the full-FD path — 33×/1166× faster on cathead/brezel, also fixes the
FD-step vs Newton-tol accuracy floor (N1 cross-fix).
V3 (input-validation): add isfinite check on all vertex coordinates in load_mesh;
NaN/Inf now throws runtime_error at the I/O boundary before poisoning the solver.
C1 (test-coverage): expose the internal ok flag via an optional bool* parameter
on solve_linear_system so double-solver failure is no longer invisible to callers.
+5 new tests (LoadMeshThrowsOnNaN/Inf, OkFlag_True*, OkFlag_NullPointerIsSafe).
282/282 tests pass.

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.
