The CGAL test build is too heavy for the eulernest runner — most recent
runs OOM during CGAL+Eigen template expansion at -j1/1600 MB rather than
exposing real regressions. Gate the job off with `if: false` and a
DISABLED-2026-05-26 comment block, matching the pattern already used for
doxygen-pages.yml and perf-compile-time.yml. test-fast and quality-gates
keep running on every push/PR; workflow_dispatch reruns of test-cgal
still work from the Gitea UI.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Both workflows used `push: branches: [main]` and have been firing on
every merge to main since v0.10.0 landed. Recent runs failed:
* `doxygen-pages.yml` runs #492/#493/#494 — failed (pages branch
went into an inconsistent state during the cleanup sequence;
the workflow's HTTPS push couldn't recover, even though manual
SSH push from a developer machine could).
* `perf-compile-time.yml` never ran a clean baseline because the
same upstream CI-container issue blocks it.
While we work through the root cause, both workflows are restricted
to `workflow_dispatch` (manual only). Effect:
* pages-branch stays at its last known-good content; merges to
main no longer trigger a (currently-failing) republish attempt
* no false-red CI badges on PRs / commits
* either workflow can still be fired manually via the Gitea
Actions UI when needed
Re-enable trick: each file has its old `push:` block commented out;
uncomment when the underlying CI push issue is fixed.
`doc-build.yaml` (Doxygen warning-stats, `continue-on-error: true`)
is unaffected — it does not push anywhere and is intentionally
informational.

Two additions that close out the reviewer-prep work cleanly:
1. doc/reviewer/hub.html + publish-workflow integration
──────────────────────────────────────────────────────
Move the hand-curated reviewer hub from the codeberg `pages`
branch (where it lived as an opaque snapshot) into the repo as
`doc/reviewer/hub.html`. `.gitea/workflows/doxygen-pages.yml`
gains a conditional `if [ -f doc/reviewer/hub.html ]; then …`
step that installs it as the publish `index.html` and demotes
the auto-generated Doxygen index to `/doxygen.html`.
Effect: merging any of the open PRs into main will trigger the
workflow, which republishes BOTH the Doxygen + the reviewer hub
together. The reviewer URL stays live across merges with zero
manual intervention.
Source-controlled benefits:
* hub edits go through normal PRs, not orphan-branch
force-pushes
* old hub versions live in git history
* the in-repo links now target `branch/main/…` instead of the
transient `preview/reviewer-snapshot-vN/…` paths
2. .gitea/workflows/perf-compile-time.yml — Linux CI bench
────────────────────────────────────────────────────────
New workflow runs on every push to main that touches the build
system or public headers. Five-step matrix measures and reports:
Run 1 cold baseline (no PCH, no Unity, no ccache)
Run 2 + PCH only
Run 3 + PCH + Unity (current default)
Run 4 + FAST_TEST_BUILD=ON (-O0 -g — Linux's expected ~40 % win)
Run 5 + ccache warm rerun (expected ≥ 90 % cache hit)
Validates the Apple-M1 predictions in doc/architecture/compile-time.md
against the Linux + g++ runner where Backend dominates more and
the Apple-clang+PCH friction that defeats ccache locally does not
apply. Job is data-collection only; never blocks a merge.
doc updates:
* doc/architecture/compile-time.md — new "Cross-platform perf bench"
section linking to the workflow + the table of macOS-vs-Linux
expected deltas.
* doc/reviewer/README.md — new "Hub-Page durability" subsection
explaining how the hub survives merges.

Two reviewer-facing additions consolidated into one commit:
(1) New `quality-gates` job in .gitea/workflows/cpp-tests.yml
──────────────────────────────────────────────────────────
Runs in parallel with test-cgal after test-fast. Installs
`codespell` + `shellcheck` (apt) into the existing ci-cpp container,
then executes four scripts strictly (exit 1 on any finding):
* license-headers.sh — 66/66 files carry SPDX MIT
* cgal-conventions.py — 0 violations across 6 CGAL public headers
* codespell.sh — 0 typos across docs + source + scripts
* shellcheck.sh — 0 findings across 16 shell scripts
Each ran at 0 findings locally before promotion. Total wall-time
on the eulernest runner: ~30 s.
(2) New code/deps/THIRD-PARTY-LICENSES.md
──────────────────────────────────────
Enumerates every vendored dep under code/deps/, plus auto-fetched
GoogleTest, plus system-required Boost, with:
* upstream project + version + SPDX identifier
* compatibility note for MIT distribution
* downstream-packager license matrix (header-only consumer vs
CLI binary) clarifying the LGPL §3 vs §4 distinction
Required for any future Linux-distribution packaging and for the
CGAL submission's compliance check.
Also fixes a `code/.gitignore` gap: the `deps/*` wildcard was
catching the new file; added `!deps/THIRD-PARTY-LICENSES.md` to
the exclusion list so it's actually tracked.

CI gates (active on every PR via .gitea/workflows/)
───────────────────────────────────────────────────
1. test-count consistency
cpp-tests.yml gains a step after test-cgal that runs
`scripts/check-test-counts.sh` against the just-built ./build dir
(reuse via new BUILD_DIR env var, ~5 s overhead). Drift between
`doc/api/tests.md` and ctest reality now fails the PR.
2. End-to-end smoke
`scripts/try_it.sh` (the documented user quick-start) is now part of
the CGAL job, so README quick-start regressions fail the PR rather
than silently breaking when users land.
3. Internal markdown link checker
New `.gitea/workflows/markdown-links.yml` + `scripts/check-markdown
-links.py`. PRs that touch any *.md file run the check; main pushes
trigger it too; a weekly cron catches external link rot. Pure
Python, no third-party action. Validated against the current tree:
122 internal links across 37 *.md files, 0 broken.
Local quality scripts (`scripts/quality/`, not in CI)
─────────────────────────────────────────────────────
* `license-headers.sh` — `SPDX-License-Identifier: MIT` audit over
code/{include,src,tests}/. Currently
reports 60/66 files missing it — that's
a follow-up; the script captures the
structural gap.
* `sanitizers.sh` — ASan + UBSan over the fast test suite.
* `coverage.sh` — gcov/lcov line + branch coverage of
code/include/, HTML report under
build-coverage/lcov-html/.
* `clang-tidy.sh` — runs the curated `.clang-tidy` policy over
every public header.
* `multi-compiler.sh` — sequential build + test against every
detected g++/clang++ (auto-discovery or
explicit list).
* `cgal-version-matrix.sh`— sequential build + CGAL test suite against
every CGAL tree under `~/cgal/<ver>/` (or
via `CGAL_ROOTS=...` env var).
* `reproducible-build.sh`— two `Release -j1` builds, fail if any test
executable byte-differs.
* `run-all.sh` — driver: `--fast` for the ~5-min subset,
no arg for the ~25–40 min full sweep;
captures per-gate logs to
build-quality-logs/.
+ `.clang-tidy` — curated, deliberately-small policy (only
checks that fire on OUR code, never on
transitive CGAL/Eigen/Boost headers).
+ `scripts/quality/README.md` — explains the structure, lists each
gate's wall-time + prereqs, and codifies
the promotion path: a gate moves into CI
only when it's green on the dev machine
AND has a recovery-instructions paragraph
in `doc/release-policy.md`.
Doc updates
───────────
`doc/architecture/locked-vs-flexible.md` (reviewer-facing) gains 4
"closed" rows in the limitations table — the 3 CI gates above and the
local quality-script suite.

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.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Replaces the hand-maintained `doc/api/headers.md` with a generated one
sourced from each header's `\file` brief and the public symbols
extracted by Doxygen into XML. The CI workflow regenerates it on every
push to main that touches the public headers.
New files
─────────
* scripts/gen-headers-md.py — parses doc/doxygen/xml/*.xml, groups
headers by directory (CGAL public / CGAL internals / Core), and
writes a markdown table with header path, first-sentence brief, and
the public symbols declared at file scope. Skips `detail::`
namespaces and template-specialisation duplicates.
* scripts/regen-docs.sh — convenience wrapper:
doxygen → gen-headers-md.py → coverage report.
Workflow changes
────────────────
.gitea/workflows/doxygen-pages.yml now:
1. Runs `bash scripts/doxygen-coverage.sh` as an informational step
(no fail threshold yet — the script supports `--threshold N` for
when we're ready).
2. Re-runs `python3 scripts/gen-headers-md.py` and warns if the
file drifted from what's in main (operator should run
`regen-docs.sh` locally before pushing).
Doxyfile hygiene
────────────────
`HTML_TIMESTAMP` was removed in Doxygen 1.10 → replaced with the new
`TIMESTAMP = NO` to silence the obsolete-tag warning.
Effect on the reviewer-facing landing pages
───────────────────────────────────────────
Every improvement to a `\file` brief at the top of a public header now
flows automatically into both:
* the Doxygen HTML at https://tmoussa.codeberg.page/ConformalLabpp/
* the markdown landing at doc/api/headers.md (rendered by Codeberg
in the repo view)
…so writers have a single source of truth (the C++ source) and
readers see the same words in both surfaces.

New .gitea/workflows/doxygen-pages.yml runs on every push to main that
touches the public headers, Doxyfile, the markdown-link filter, any
doc/**/*.md, README.md, or the workflow itself. It reuses the existing
ci-cpp container image and the existing CODEBERG_TOKEN secret already
used by mirror-to-codeberg.yml — no new secret setup needed.
The job force-pushes an orphan commit to the `pages` branch on
codeberg.org/TMoussa/ConformalLabpp, which Codeberg Pages serves from
https://tmoussa.codeberg.page/ConformalLabpp/ (verified live).
README.md gains a Doxygen badge and a Documentation table row pointing
at the Pages URL. locked-vs-flexible.md (the reviewer-facing doc) is
updated to mention the Pages URL next to the Doxygen-coverage gap.

Gitea Actions on GHES does not support actions/upload-artifact@v4 — the
v4 release switched to GitHub-only APIs (artifact backend rewritten).
The doc-build job was failing with "artifact@v4+ are not currently
supported on GHES."
Changes
───────
* Removed the artifact-upload step entirely. Rationale: the warning
summary in the job log is the primary reviewer signal for the
documentation health check. Reviewers who want to inspect the HTML
locally can rebuild it with `cmake --build build --target doc`.
* Removed the apt-get install step. Doxygen is now pre-installed in
the ci-cpp container (Dockerfile change earlier in this PR).
* Added an explanatory comment so the missing artifact step is not
re-introduced unknowingly.
* Added a "Report HTML output" step that prints file count + total size
for visibility (a no-op if the HTML directory is absent).
When/if a real artifact host appears (Gitea Pages, S3, GitHub mirror
release), this job can be extended to publish the HTML there. For now,
the in-log warning summary is sufficient.

Two CI improvements:
1. **test-cgal OOM fix**
* memory limit 1400m → 1600m (cc1plus needs ~700 MB for CGAL + Eigen)
* memory-swap 1400m → 1600m (was less than memory, Docker rejected
the config; now disables swap entirely
so OOM fails fast)
* build parallelism -j2 → -j1 (single worker leaves headroom)
These three changes together address the test-cgal failures observed
since the test_scalability_smoke.cpp was added. Locally the full
suite (183 tests including the brezel.obj genus-2 mesh) runs in
~1 s with peak ~700 MB; the ARM64 CI runner now has the same
headroom.
2. **API-docs job (new, soft-fail)**
* .gitea/workflows/doc-build.yaml — separate workflow, distinct name
"API Docs"
* Runs only on pull requests; `continue-on-error: true` ensures
warnings never block the merge
* Installs doxygen, runs `doxygen Doxyfile`, uploads the generated
HTML as a 14-day artifact for reviewer inspection
* Dockerfile.ci-cpp also pre-installs doxygen so future iterations
can drop the in-job install step
When Doxygen coverage matures (Phase 8c — User_manual.md), this job
can be promoted to a hard requirement and the HTML deployed to
Pages.

Unified the codebase language to English throughout. German text appeared
in code comments, test file headers, CI step names, and several markdown
documents. All natural-language text is now English; proper nouns
(Institut für Mathematik, Technische Universität Berlin) are unchanged.
Files changed:
- .gitea/workflows/cpp-tests.yml — CI step names and job comments
- code/include/mesh_utils.hpp — inline comment
- code/tests/cgal/CMakeLists.txt — section comment block
- code/tests/cgal/test_geometry_utils.cpp — full file header + all test comments
- doc/math/references.md — geometry-central section
- doc/math/validation.md — Section 9 (geometry-central cross-validation)
- doc/roadmap/phases.md — Optional geometry-central track (GC-1/2/3)

Reduces Pi load: test-cgal now triggers only when a PR is opened/updated,

-j$(nproc) during CGAL+Eigen template compilation consumed ~1.5-2 GB
peak RAM on the Raspberry Pi CI runner, starving the Gitea web server.
Changes:
- CGAL build: -j$(nproc) → -j2 (halves peak memory, ~700 MB per process)
- Both builds: nice -n 19 (lowest CPU priority, web server keeps preemption)
- test-cgal container: hard memory cap --memory=1400m --memory-swap=1400m
so the container is OOM-killed rather than taking down the whole system

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

The ci-cpp image was likely built for linux/amd64; the eulernest runner
is linux/arm64 (Raspberry Pi), so the container exited immediately
without running any steps (task 102 log: 10 lines, no step output).
Fix: run directly on the host runner and install cmake/g++ via apt-get
(same approach as the previously working workflow).
Also pin --platform=linux/arm64 in Dockerfile.ci-cpp so the next
image build produces the correct architecture. Once the image is pushed,
re-add the container: block to the workflow.
