quality: 4 more gates + dependency audit; full --fast sweep 10/10 green
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 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

quality: add code-style + CGAL-convention checkers (local-only)
Closes the gap "no code-quality / convention gate" from the structural
review. Three new artefacts, all local-only (CI promotion deferred
until the existing tree is 100 % clean under each):
1. .clang-format — project's existing style mechanically captured
(4-space indent, opening brace on new line for class/struct/function,
left-aligned pointer/reference modifiers, aligned `using = ...` blocks,
100-col loose limit, no include re-ordering — matches code/include/
today).
2. scripts/quality/clang-format.sh — drift detector. Dry-run mode by
default (always exits 0); --strict to fail on drift; --fix to apply
suggested changes in place. Skips code/deps/ and macOS-duplicate
files.
3. scripts/quality/cgal-conventions.py — checker for the CGAL idioms
that clang-format/clang-tidy cannot express:
CGAL-1 include-guard format `CGAL_<DIRS>_<FILE>_H`
CGAL-2 every public header has a `\\file` Doxygen brief
CGAL-3 no nested namespaces beyond the allowed set
(CGAL::parameters, CGAL::Conformal_map, internal_np, IO)
CGAL-4 named-parameter tag types end in `_t`; value object does not
CGAL-5 no `using namespace ...` at file scope (header leakage)
CGAL-6 no #define beyond CGAL_* / include-guard
Result on the current tree: 6 CGAL public headers, 0 violations.
The checker therefore doubles as documentation of the conventions
we already follow.
Both are wired into scripts/quality/run-all.sh's fast subset (~5 s
combined wall time). README.md updated to split the gates into a
"style/convention" group (cheap, run-on-every-commit material) and a
"correctness/quality" group (slow, run-before-tag material).
The reviewer-facing locked-vs-flexible.md gains another "✅ Closed"
row documenting both gates and the 0-violation baseline.

ci+quality: structural gates (CI: 3 new; local: 7 new + .clang-tidy)
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.

docs: auto-generate doc/api/headers.md from Doxygen XML
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.

docs(doxygen): fix critical extraction bug; baseline 24% → 42% on public API
ROOT CAUSE FIX
The Doxyfile EXCLUDE_PATTERNS line contained `*/* 2.hpp` (note the
space — a stray glob from macOS-style "foo 2.hpp" duplicate files).
That pattern was silently matching ALL .hpp / .h files, so Doxygen was
indexing nothing under code/include/. The pre-existing 556 KB of HTML
output was effectively documenting only README.md, CLAUDE.md and a
small stub for std:: — not the C++ API at all.
After fixing the pattern (and properly escaping the space-prefixed
"foo 2.hpp / foo 2.h" macOS-dup patterns), Doxygen now extracts 141
compounds and emits 248 HTML pages from the public headers.
WHAT THIS PR ADDS
1. Doxyfile fix: correct EXCLUDE_PATTERNS; add GENERATE_XML for the
coverage measurement script; add MathJax for `$$...$$` math in
markdown; add the missing CGAL `\cgalParamNBegin/End/Description/
Default/...` aliases so CGAL-style param blocks render correctly.
2. New headers:
- code/include/CGAL/Conformal_map/doxygen_groups.h
defines `PkgConformalMap{,Ref,Concepts,NamedParameters}`,
resolving 17 prior "non-existing group" warnings.
- code/include/CGAL/Conformal_map/doxygen_namespaces.h
gives every namespace under `CGAL::` and `conformallab::` a
brief description.
3. New tool: scripts/doxygen-coverage.sh
Parses the XML output and reports % of public symbols (excluding
the `detail::` implementation namespaces by default) that have a
non-empty brief/detailed description. Supports `--list-undoc`
and `--threshold N` for CI integration.
4. Substantial docstring additions to the public CGAL headers:
`Conformal_map_traits.h`, `Discrete_circle_packing.h`,
`Discrete_inversive_distance.h`, `conformal_mesh.hpp`,
`Discrete_conformal_map.h` (Hyper_ideal_map_result fields).
5. Markdown housekeeping that the strict-warning Doxygen run surfaced:
tests.md (escape literal `#` in table cell),
locked-vs-flexible.md (broken section anchor),
overall_pipeline.md (replace `$$LaTeX$$` with inline-unicode math).
CURRENT NUMBERS
before: ~24% documented (public API; the prior "87%" claim was
based on the broken extraction)
after: 42% documented (165 of 396 public symbols)
warnings: 0 (was 27 spurious + a flood of bogus undocumented
warnings hidden by the buggy EXCLUDE pattern)
NEXT (in a follow-up commit on this branch)
The remaining 231 public symbols (mostly in `layout.hpp`,
`hyper_ideal_functional.hpp`, `spherical_functional.hpp`, the per-mode
functional/Hessian files) can be brought to ~100% with another pass of
short `///` brief descriptions. The coverage script is the gate; CI
can begin enforcing `--threshold 95` once the next pass lands.

ci: auto-publish Doxygen HTML to Codeberg Pages on main
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.

docs: clean Doxygen warning log (0 warnings) + flag honest gaps to reviewer
Doxygen now builds with **0 warnings** (was 27). Root cause: `[label](doc/api/tests.md)`-style relative markdown links in README.md and CLAUDE.md were being interpreted by Doxygen as \ref commands and failed to resolve (Doxygen indexes .md files by basename, not by repo-relative path). Fix: add a per-file `FILTER_PATTERNS` to Doxyfile that rewrites `[label](path/to/file.md)` into `<a href="path/to/file.md">label</a>` just for Doxygen. HTML anchors bypass \ref resolution entirely; the generated Doxygen HTML still hyperlinks correctly. The on-disk markdown is untouched, so GitHub rendering is unaffected. New file: scripts/doxygen-md-filter.sh (24 lines, documented). Also: append a "Known limitations (state at the time of the reviewer meeting)" table to doc/architecture/locked-vs-flexible.md so the external reviewer sees the 7 deliberate gaps (output_uv_map covers 3 of 5 entries; pipe-only chaining; Phase 9b-analytic derived but not implemented; Doxygen WARN_IF_UNDOCUMENTED policy; CI test-count gate; research-track utilities) with effort estimates next to each.

Phase 8b-Lite: pipe-operator chaining for named parameters
Some checks failed
C++ Tests / test-fast (push) Successful in 1m58s
C++ Tests / test-fast (pull_request) Successful in 2m33s
API Docs / doc-build (pull_request) Successful in 51s
C++ Tests / test-cgal (push) Has been skipped
C++ Tests / test-cgal (pull_request) Failing after 10m32s
Adds `operator|` in `namespace CGAL` so package-local named parameters
can be combined left-to-right without modifying CGAL upstream:
auto p = CGAL::parameters::gradient_tolerance(1e-12)
| CGAL::parameters::max_iterations(500)
| CGAL::parameters::output_uv_map(uv);
CGAL::discrete_conformal_map_euclidean(mesh, p);
Why not the canonical `.a().b().c()` syntax
───────────────────────────────────────────
CGAL's standard chaining mechanism requires registering each named
parameter as a member function on `Named_function_parameters` via the
`CGAL_add_named_parameter` macro in
`CGAL/STL_Extension/internal/parameters_interface.h` — a vendored
upstream file that conformallab++ deliberately treats as read-only.
Adding member-function chainers for our package-local tags would
require either forking CGAL or modifying the vendored copy. Neither
is acceptable for a library that wants to remain portable across
future CGAL releases.
The pipe-operator achieves the same compositional semantics via a
free function in `namespace CGAL` (so ADL finds it for
`Named_function_parameters` operands). Implementation: rebuild the
right-hand-side `Named_function_parameters` with the left-hand-side
as its `Base`, producing an indistinguishable chain that every entry
function accepts unchanged.
Implementation: `code/include/CGAL/Conformal_map/internal/parameters.h`
lines 158-187. The operator is constrained to right-hand-sides with
`No_property` base (i.e. fresh single-parameter packs from the helper
functions), so it never collides with any future CGAL operator on the
same type.
Tests (2 new, total Phase-8b-Lite suite 15 → 17)
────────────────────────────────────────────────
* CGALPhase8bLite.NamedParamPipe_MultipleParamsTakeEffect
Chain three parameters; verify all three take effect (tight
tolerance respected + UV pmap populated + iteration cap honoured).
* CGALPhase8bLite.NamedParamPipe_TwoParams
Chain two parameters; verify max_iterations(0) blocks the loop
even when combined with another param.
Full CGAL suite: 234/234 PASSED, 0 SKIPPED (was 232).
Total: 257/257 PASSED, 0 SKIPPED (was 255).
scripts/check-test-counts.sh: OK.
Documentation updates
─────────────────────
* doc/tutorials/add-output-uv-map.md §3.4: "Current limitation: no
chaining" → "Chaining: use the pipe operator `|`". Explains why
CGAL's `.member()` syntax isn't available and shows the `|`
workaround with a working code example.
* doc/architecture/locked-vs-flexible.md §8: chaining now flagged as
shipped via pipe; recommended posture says `.member()` chaining
only if a user pushes for the CGAL-canonical syntax.
* doc/roadmap/porting-status.md §5: API limitations table updated.
* doc/api/tests.md: CGALPhase8bLite row 15 → 17, total 232 → 234.

docs: 5-document meeting prep — tutorials + research note + status + architecture
External-reviewer-visit prep package (Springborn-Bobenko PhD alumnus,
2026-05-26). All five documents target the same audience: a
mathematician who wants to evaluate, extend, or contribute to
conformallab++. Goal: make the project maximally hackable BEFORE the
meeting. Code unchanged in this commit — pure documentation.
Files added
───────────
1. **doc/tutorials/block-fd-hessian.md** (460 lines)
Step-by-step tutorial on the per-face block-FD Hessian pattern
shipped in Phase 9b (96× speed-up). Matches the style of
add-inversive-distance.md. Covers:
* The per-face locality lemma (mathematical justification).
* Cost analysis (full-FD vs block-FD vs analytic).
* Implementation walkthrough through face_angles_from_local_dofs +
hyper_ideal_hessian_block_fd.
* Porting checklist for applying the same pattern to a new
functional.
* The four cross-validation criteria.
* When NOT to use block-FD + upgrade path to Phase 9b-analytic.
2. **doc/tutorials/add-output-uv-map.md** (477 lines)
Tutorial for the `output_uv_map` named-parameter pattern shipped in
PR #14. Covers:
* The UX problem (two-step pipeline → one-call wrapper).
* The CGAL named-parameter mechanism + how the entry functions
wire it (get_parameter + constexpr if).
* Step-by-step recipe for adding a new named parameter (worked
example: hypothetical `output_holonomy_map`).
* The five test patterns for verification.
* Why CP-Euclidean (face-DOF) and Inversive-Distance (Luo-edge-length)
do not yet support output_uv_map — what is needed to add them.
3. **doc/math/hyperideal-hessian-derivation.md** (805 lines)
Research-quality LaTeX-formatted derivation of the analytic
HyperIdeal Hessian via the Schläfli identity (Phase 9b-analytic
preparation). Covers:
* Schläfli identity (1858/60) — gradient and second-order form.
* Derivatives of ζ, ζ₁₃, ζ₁₄, ζ₁₅ (all hyper-ideal-to-fully-ideal cases).
* Chain rule for ∂β_i/∂(b,a) and ∂α_ij/∂(b,a) — case-split on the
four α_ij branches.
* Per-face 6×6 block formulas.
* Acceptance criteria for the future implementation.
* Implementation outline (Conformal_map header sketch).
* Appendix A: sign / argument-order pitfalls reading the code.
* References: Schläfli 1858, Milnor 1982, Vinberg 1993, Cho-Kim 1999,
Rivin, Glickenstein 2011, Springborn 2020, BPS 2015.
4. **doc/roadmap/porting-status.md** (~250 lines)
Operational snapshot of "where is each piece of Java math today"
at v0.9.0. Sections:
* 25 000 lines of Java in one table (ported / worth porting /
intentionally skipped breakdown).
* Five DCE models — full status matrix with Java port status,
Hessian type, Newton support, CGAL entry, UV-output capability.
* Topology + solver infrastructure status.
* CGAL public API map + known limitations (no chaining, Surface_mesh
only, submission-readiness gaps).
* Reverse cross-reference: Java class → C++ port location (or
"skipped: replaced by …" / "in roadmap: phase X").
* Things in C++ that the Java original does NOT have (research
extensions track).
* "How to use the library today" quickstart.
5. **doc/architecture/locked-vs-flexible.md** (~270 lines)
12-item architecture-decision review with tier classification
(🔴 load-bearing / 🟡 semi-fixed / 🟢 opportunistic). Each item
includes: locked-since date, cost to change, when to revisit,
recommended posture for new contributors. Key insight stated up
front: "the load-bearing decisions are all good in 2026". Closes
with five open questions for the external reviewer — items where
a second opinion would genuinely help (Phase 9c algorithm choice,
Phase 10a priorities, analytic-Hessian payoff justification,
CGAL upstream vs independent distribution, geometry-central
cross-validation).
Total: ~2 250 lines across five new docs.

docs: add StereographicUnwrapper + CircleDomainUnwrapper to roadmap
Audit found that 2 of the 4 Java-port candidates from the conformal-
mapping discussion were missing from the documentation:
* StereographicUnwrapper (266 Java LoC) — projects spherical layout
S² → ℂ via stereographic projection + Möbius centring. Closes the
visualisation gap from discrete_conformal_map_spherical() which
currently returns Point_3 on S²; downstream uses typically want a
2-D atlas. Suggested phase: 10b' (alternative methods, parallel
to Hyperbolic / Quasi-isothermic). Effort: small (~3 days).
* CircleDomainUnwrapper (570 Java LoC) — conformal map of a
multiply-connected planar region onto a disk-with-holes (Koebe's
general uniformization theorem 1909). A use-case class
conformallab++ does not currently cover (annulus, slit torus,
fluid flow around obstacles, electrostatics with multiple
conductors). Suggested phase: 11c. Effort: large (~2 weeks).
Added to all three roadmap documents:
* doc/roadmap/java-parity.md — worth-porting table extended
* doc/roadmap/research-track.md — Java-backlog summary extended
* doc/roadmap/phases.md — Phase 10b' bullet + new
Phase 11c block with full math
context (Koebe 1909 reference,
classical complex-analysis use cases).

Phase 8b-Lite extension: output_uv_map named parameter for integrated layout
Closes the UX gap identified in the Phase-8b-Lite design discussion:
the four classical-DCE CGAL entries now optionally run their `*_layout()`
step internally if the caller supplies `CGAL::parameters::output_uv_map(pmap)`.
Before this PR, the workflow was:
auto res = CGAL::discrete_conformal_map_euclidean(mesh);
// ... user has to re-set up maps, re-pin vertex, then ...
auto layout = euclidean_layout(mesh, res.x, maps);
// ... and copy coordinates into a property map manually.
After this PR:
auto uv = mesh.add_property_map<Vertex_index, K::Point_2>("uv", ...).first;
CGAL::discrete_conformal_map_euclidean(
mesh, CGAL::parameters::output_uv_map(uv));
// ... uv now populated for every vertex.
Coverage
────────
* `discrete_conformal_map_euclidean` — `Point_2` per vertex.
* `discrete_conformal_map_spherical` — `Point_3` per vertex (on S²).
* `discrete_conformal_map_hyper_ideal` — `Point_2` per vertex (Poincaré disk).
CP-Euclidean and Inversive-Distance entries do not yet support
`output_uv_map` — face-based packing has no per-vertex UV concept, and
inversive-distance needs a dedicated layout routine that uses Luo's
edge-length formula (planned follow-up).
New named parameters (`code/include/CGAL/Conformal_map/internal/parameters.h`)
─────────────────────────────────────────────────────────────────────────────
* `output_uv_map(pmap)` — write coordinates into pmap after layout.
* `normalise_layout(bool)` — apply post-layout canonical normalisation
(PCA centroid for Euclidean, north-pole alignment for Spherical,
Möbius centring for Hyper-ideal).
Both follow the existing Phase-8a-MVP named-parameter convention.
Chained syntax (`.output_uv_map(...).normalise_layout(true)`) is not
yet supported — pass them one at a time.
Tests (5 new in test_cgal_phase8b_lite.cpp)
───────────────────────────────────────────
* `OutputUvMap_Euclidean_PopulatesPmap` — UVs are finite + non-trivial.
* `OutputUvMap_Spherical_PopulatesXyz` — every output on unit S².
* `OutputUvMap_HyperIdeal_PointsInPoincareDisk` — |p|² ≤ 1 if converged.
* `OutputUvMap_Absent_DoesNotRunLayout` — no parameter ⇒ no layout.
* `OutputUvMap_NormaliseLayout_TakesEffect` — both raw + norm calls
return finite UVs (named-parameter chaining limitation documented).
All five pass. Full CGAL suite: 232/232, 0 skipped (was 227).
doc/api/tests.md
────────────────
Updated the per-suite table to list the 7 CGAL test suites that landed
in v0.9.0 (8a MVP + 9a + 9b + 8b-Lite) but had not yet been added to the
canonical table. Total: 227 → 232. This brings the doc back in sync
with `ctest` output and unblocks future `scripts/check-test-counts.sh`
runs.

docs: audit-driven fixes — stale claims, missing v0.9.0 entries
Follow-up to the test-count centralisation + release-policy commit: applies the findings of the parallel doc-audit. Stale claims fixed ────────────────── * CLAUDE.md line 14-17 (phase block summary): expanded from "Phase 1-7 done, 8-9 planned, 10+ research" to reflect that Phase 8a MVP + 8b-Lite + 9a + 9b are now done (v0.9.0), with Phase 9b-analytic + 9c as the next planned milestones. * CLAUDE.md line 251-252 (release state): "v0.7.0 ... Phase 7 next" → "v0.9.0 ... Phase 9c + 9b-analytic next". * CLAUDE.md "Three geometry modes" → "Five DCE models" table. Adds CP-Euclidean and Inversive-Distance rows with their CGAL public entries. DOF-assignment pattern subsection rewritten to cover vertex-only / vertex+edge / face-based assignments. * CLAUDE.md "Newton solver" section: gradient sign and Hessian convention for all five solvers (was: three). Replaces the "Hessian is FD" claim for HyperIdeal with the block-FD note (Phase 9b shipped). * CLAUDE.md "Known quirks": stale GTEST_SKIP entry removed (v0.9.0 cleaned up the HDS-port stubs). * README.md line 86: "all 24 headers with descriptions" → "all public headers with descriptions" (was undercounting). Missing entries added — `doc/api/headers.md` ───────────────────────────────────────────── * New section **"Circle-packing functionals (Phase 9a)"** with `cp_euclidean_functional.hpp` and `inversive_distance_functional.hpp`. * New section **"Math utilities"** documenting four previously- undocumented public helpers: `matrix_utility.hpp`, `projective_math.hpp`, `p2_utility.hpp`, `discrete_elliptic_utility.hpp`. * New section **"CGAL public API (Phase 8b-Lite)"** documenting all six new public headers under `include/CGAL/`. * `newton_solver.hpp` row expanded to list all five Newton functions. Header count summary (before vs after): * Before: 24 headers in 8 sections (missing 6 of the 30 actually present). * After: 30 headers in 11 sections (complete coverage).

docs: centralise test counts + add release-policy + remove stale stub references
Two complementary improvements aimed at reducing recurring maintenance
overhead:
1. **Test-count centralisation** — `doc/api/tests.md` is now the
single source of truth for the test counts. All other docs
(README, CLAUDE.md, doc/contributing.md, doc/getting-started.md,
doc/math/validation.md, doc/math/validation-protocol.md,
scripts/try_it.sh) use qualitative phrasing + a link instead of
hardcoded numbers. The previous regime had eight places with
"227 CGAL tests, 23 non-CGAL tests" that drifted apart across
releases (the v0.9.0 release-prep needed to touch nine files).
2. **Versioning policy** — `doc/release-policy.md` (new, ~250 lines)
formalises:
* SemVer rules for the pre-1.0 and post-1.0 phases.
* Phase-milestone → MINOR-bump mapping (v0.10.0 → Phase 9c, …).
* Single-source-of-truth table for moving numbers (test counts,
version, date).
* Step-by-step release process (the recipe that worked for v0.9.0
after the false-start with PR #11/#12).
* Hotfix policy + post-1.0 deprecation policy.
* Known failure modes and how to recover from them.
Plus a small CI gate:
3. **scripts/check-test-counts.sh** — verifies the totals in
doc/api/tests.md match `ctest` output. Re-uses existing build-cgal/
if present. Exit 0 on match, 1 on divergence with recovery hints.
Cheap enough (~30 s) to run on every PR.
Other cleanups
──────────────
* code/tests/cgal/CMakeLists.txt — stale "Test 7 (genus-2 homology)
as GTEST_SKIP stub until Phase 8" comment removed; that test landed
as HomologyGenerators.Genus2_FourCutEdges in Phase 7.
* CLAUDE.md — "test-fast also runs stubs" Known Quirks entry updated
to reflect the v0.9.0 stub cleanup (no GTEST_SKIPs remain).
* CLAUDE.md doc map — new entry for doc/release-policy.md.
Stubs audit
───────────
Zero GTEST_SKIP() calls remain in the codebase as of this commit.
The only references to stubs are in historical documentation
(CHANGELOG.md v0.7.0 entry, doc/roadmap/* "deferred to research-track"
notes) — those are intended.

release: v0.9.0 — finalise PR #11 with CHANGELOG, version bump, stub cleanup
Closes the v0.9.0 release loop on top of Phase 9a-Newton + Phase 8b-Lite: * CHANGELOG.md (NEW) — Keep-A-Changelog format, with v0.9.0 entry detailing all Phase 9a / 9b / 8b-Lite contents and the doc-audit corrections that landed via PR #10. * CITATION.cff — version 0.7.0 → 0.9.0, date 2026-05-18 → 2026-05-22. * Stale HDS-port stubs removed (13 GTEST_SKIPs total): - code/tests/test_spherical_functional.cpp - code/tests/test_hyper_ideal_functional.cpp - code/tests/test_hyper_ideal_hyperelliptic_utility.cpp These referenced a "HDS port (Phase 4)" that never happened — CoHDS was intentionally replaced by CGAL::Surface_mesh, and the functional tests live in code/tests/cgal/test_*_functional.cpp. * Test-count updates everywhere: - Non-CGAL 36 → 23 (drop = 13 deleted stubs) - CGAL 176 → 227 - Total 212 → 250 (+38 net, 0 skipped) Files: README.md, CLAUDE.md, CHANGELOG.md, scripts/try_it.sh, doc/api/tests.md, doc/contributing.md, doc/getting-started.md, doc/math/validation.md.

Phase 9a-Newton: newton_cp_euclidean + newton_inversive_distance
Some checks failed
C++ Tests / test-fast (push) Has been cancelled
C++ Tests / test-cgal (push) Has been cancelled
C++ Tests / test-fast (pull_request) Successful in 2m28s
API Docs / doc-build (pull_request) Successful in 52s
C++ Tests / test-cgal (pull_request) Failing after 11m29s
Wires the two Phase-9a functionals into the Newton-solver layer so
they are operational end-to-end. CGAL test count: 212 → 219 (+7).
Solvers
───────
* newton_cp_euclidean(mesh, x0, m, tol, max_iter)
- Uses cp_euclidean_hessian — analytic 2×2-per-edge BPS-2010
formula h_jk = sin θ / (cosh Δρ − cos θ).
- SparseQR fallback handles the gauge-singular case when no face
is pinned (caller error, but we recover gracefully).
- Strictly-convex energy ⇒ quadratic convergence near optimum.
* newton_inversive_distance(mesh, x0, m, tol, max_iter, hess_eps)
- Uses an inline FD Hessian (n × gradient evaluations per step) —
mirrors the Phase 4a HyperIdeal solver in spirit.
- Analytic alternative via Glickenstein 2011 eq. (4.6) is tracked
in doc/roadmap/research-track.md as Phase 9a.2-analytic.
- Sensitive to initial point; the test suite always starts from
a natural-theta setup (u = 0 is the equilibrium when
compute_inversive_distance_init_from_mesh was called).
Tests (test_newton_phase9a.cpp, 7 cases)
────────────────────────────────────────
* CPEuclidean_NaturalPhi_ClosedTetrahedron_ConvergesInZeroIterations
* CPEuclidean_PerturbedStart_ConvergesBackToEquilibrium
* CPEuclidean_OpenTetrahedron_NaturalPhi_Converges
* InversiveDistance_NaturalTheta_Triangle_ConvergesInZero
* InversiveDistance_PerturbedQuadStrip_Converges
* InversiveDistance_PerturbedTetrahedron_Converges
* CPEuclidean_UsesAnalyticHessian
Regression guard: 3-DOF problem converges in ≤ 10 iterations even
with strong perturbation, confirming the analytic Hessian path is
actually used.
All seven tests pass. Full CGAL suite: 219/219 PASSED, 0 SKIPPED.
Roadmap additions (`doc/roadmap/phases.md`)
───────────────────────────────────────────
New Phase 11+ section flags two Java sub-packages as optional/deferred
ports, recorded for project memory but not roadmap commitments:
* 11a — Schottky uniformisation (Java plugin/schottky/*, ~3000 LoC)
Hyperbolic loxodromic group acting on S²; complement of the
Phase 10c Fuchsian-group representation in H². Requires
Phase 10b period matrix + Möbius-group machinery from Phase 7.
Effort: very large (4-6 weeks).
* 11b — Riemann maps (Java plugin/riemannmap/*, ~1500 LoC)
Discrete Riemann mapping theorem; texture mapping of bounded
planar regions, classical conformal mapping for engineering.
Requires Phase 10b' quasi-isothermic or Phase 9a.1 CP-Euclidean.
Effort: large (3-4 weeks).
Both are explicitly NOT roadmap commitments — they live in the doc so
they aren't re-discovered.

Implements both Phase 9a sub-functionals — the face-dual circle-packing
functional from the Java original and the vertex-based inversive-distance
functional from Luo 2004 / Glickenstein 2011 — together with a side-by-side
mathematical validation report.
CGAL test count: 194 → 205 (+11 from 9a.2, +10 from 9a.1, was already
+1 from 9a.1's setup defaults regression).

docs: full audit — fix 4 wrong port/research labels + consolidated research-track
Some checks failed
C++ Tests / test-fast (push) Successful in 2m50s
C++ Tests / test-fast (pull_request) Successful in 2m36s
API Docs / doc-build (pull_request) Successful in 1m10s
C++ Tests / test-cgal (push) Has been skipped
C++ Tests / test-cgal (pull_request) Failing after 10m25s
A full audit of `doc/` plus root-level markdown files (27 files) against
the actual ground truth in the C++ code and the local Java repository at
`/Users/tarikmoussa/Desktop/conformallab/` revealed four pre-existing
mis-labels and a stale test count. All are corrected here.
Audit findings — corrected
─────────────────────────
1. **`InversiveDistanceFunctional` mis-labelled as Java port** (4 doc sites)
Empirical verification:
find /Users/tarikmoussa/Desktop/conformallab -iname "*nversive*"
(zero matches)
The class does NOT exist in `de.varylab.discreteconformal`. The C++
implementation is built from Luo 2004 + Glickenstein 2011 + Bowers-
Stephenson 2004 — new research, not a port.
Fixed in: java-parity.md, references.md, add-inversive-distance.md.
2. **HyperIdeal Hessian mis-labelled as "Java has analytic Hessian"**
Empirical verification: `HyperIdealFunctional.java:295-298`:
public boolean hasHessian() { return false; }
Java has NO Hessian at all. Both the FD (Phase 4a) and the block-FD
(Phase 9b) Hessians in C++ are research beyond the Java port. The
chain rule (b,a) → ℓ → ζ → α/β is the *mathematical formulation*
from Springborn 2020, not something Java implements.
Fixed in: java-parity.md.
3. **Stale test count** README:87 said "28 suites, 170 tests" — current
actual is 35 suites, 176 CGAL + 36 non-CGAL. Fixed.
4. **Tutorial framing** — `add-inversive-distance.md` was framed as
"porting an InversiveDistanceFunctional.java" that does not exist.
Rewritten as "Implementing the Inversive-Distance functional from
Luo 2004" with prominent verification block at top.
New document: `doc/roadmap/research-track.md`
─────────────────────────────────────────────
Consolidates everything in conformallab++ that goes beyond a Java port:
* Items already on `main`: HyperIdeal FD Hessian, period matrix τ
partial-research components, Möbius holonomy storage.
* Items on open PRs: CP-Euclidean (PR #8, port), Inversive-Distance
(PR #8, research), block-FD Hessian (PR #9, research).
* Planned research with full citations:
- **Phase 9b-analytic** — full analytic HyperIdeal Hessian via
Schläfli identity (Schläfli 1858/60) and chain rule through
ζ₁₃/ζ₁₄/ζ₁₅, citing Springborn 2020 §4, Cho-Kim 1999,
Glickenstein 2011 §4. Includes acceptance-criteria checklist
(per-case derivative cross-checks, gauge null space, PSD,
measured ≥ 3× speed-up, LaTeX correctness note).
- **Phase 9a.2-analytic** — analytic inversive-distance Hessian
via Glickenstein 2011 eq. (4.6).
- **Phase 10c** — full uniformization for genus g ≥ 2 (Fuchsian
group representation) — fully new research, no Java reference.
- **geometry-central** GC-1/2/3 exploratory track.
* Java backlog summary: 11 worth-porting Java classes identified by
the parallel survey (FundamentalPolygonUtility, DiscreteHarmonicForm-
Utility, DiscreteHolomorphicFormUtility, CanonicalBasisUtility,
HyperbolicCyclicFunctional, QuasiisothermicUtility, KoebePolyhedron, …).
~6 500 Java lines, ~5 months of porting work, organised by phase.
Updated documents
─────────────────
* CLAUDE.md
- New "Port-vs-research maintenance rule" with empirical verification
command and the four corrected mis-labels.
- Doc map: 23 → 24 documents (research-track.md added).
* README.md
- Test count corrected (170 → 176+36).
* doc/math/references.md

- New entries for Bowers-Stephenson 2004, Glickenstein 2011,
Bobenko-Pinkall-Springborn 2010, Schläfli 1858/60.
* doc/roadmap/phases.md
- Phase 9 reorganised: 9a split into 9a.1 (port) / 9a.2 (research),
9b clarified as research (Java has no Hessian), 9c expanded with
Java line counts and effort estimates.
- Phase 10 reorganised: 10a/10b/10c with their Java prerequisites
explicitly listed; 10c flagged as "fully new research".
- Phase 10b' added: parallel research track (hyperbolic functional,
quasi-isothermic, Möbius centering).
- Phase 10c' added: optional Java-port additions (Koebe, circle
patterns, electrostatic sphere).
* doc/roadmap/java-parity.md
- Inversive-distance row: ❌ Java, ❌ C++ (Phase 9a.2) — new research.
- CP-Euclidean row added: ✅ Java, ❌ C++ (Phase 9a.1) — port.
- HyperIdeal Hessian row: ❌ Java, ⚠️ FD + block-FD in C++.
- Worth-porting table replaced with the survey results (12 classes,
Java line counts, suggested phases).
- "HyperIdeal Hessian: FD vs analytic" section rewritten with the
correction notice.
* doc/tutorials/add-inversive-distance.md
- Rewritten end-to-end with prominent verification block at top.
- Now correctly framed as "Implementing the Inversive-Distance
functional from Luo 2004" — research, not port.
- Includes the four required cross-validations:
limit cases, Bowers-Stephenson round-trip, FD-vs-analytic,
cross-validation against euclidean_functional at u=0.
- New "How to know if it's a port or research" closing section
with the empirical verification command.

docs: refine Phase 8 strategy to Hybrid MVP — MVP first, port second
Re-evaluated cost/benefit of Phase 8 vs Phase 9 after distinguishing three
concurrent goals:
• Goal A (Port): ~90% done, ~3 weeks remaining
• Goal B (CGAL): speculative, 12+ months, uncertain submission
• Goal C (Tool): research utility with novel features
Phase 8 full (3–4 weeks) would mostly serve Goal C plus optional Goal B.
Phase 9 (3 weeks) finishes Goal A unconditionally. Building Phase 8 in
full before Phase 9 risks 3-4 weeks of speculative architecture for a
hypothetical CGAL submission.
New strategy: Hybrid MVP.
Phase 8 MVP (3–5 days):
Conformal_map_traits.h concept + Default<Surface_mesh,K>
Discrete_conformal_map.h ONE entry: _euclidean()
4 named parameters Theta-map, max_iter, tol, pin
Concept-check header + Doxygen
Phase 9a (3–5 days): Inversive-Distance vs MVP API = acceptance test
Phase 9b + 9c (~2 weeks): Port truly complete
Phase 8 extensions: Only on concrete trigger
8a.2 generic FaceGraph trigger: Polyhedron_3 user
8c full doc trigger: submission planned
8d CGAL-format tests trigger: submission planned
8e YAML pipeline orthogonal, any time
Net committed budget: ~4 weeks for "port complete + CGAL MVP",
not 6–8 weeks for full Phase 8 + Phase 9.

Phase 7.5: Doxygen infrastructure + Phase 8 design freeze
Adds the Doxygen documentation pipeline as the bridge from Phase 7
(porting complete) to Phase 8 (CGAL package). Also captures the
strategic Phase 8 decisions taken on 2026-05-19.
Infrastructure
──────────────
* Doxyfile — CGAL-style minimal configuration, HTML-only,
INPUT=code/include + doc/, excludes deps/ and
macOS Finder duplicates
* code/CMakeLists — `doc` target via find_package(Doxygen QUIET);
silently disabled if Doxygen is not installed
* README — `cmake --build build --target doc` instructions
* .gitignore — exclude doc/doxygen/ output
Phase 8 strategic decisions (recorded in doc/api/cgal-package.md)
────────────────────────────────────────────────────────────────
* Submission to CGAL: pre-submission-ready, 12+ months horizon, MIT preserved
* Mesh-type flexibility: generic FaceGraph + HalfedgeGraph
* Parameter style: CGAL Named Parameters
* Default kernel: Simple_cartesian<double> (status quo)
* Architecture: 3-layer wrapper, no algorithm duplication
* Acceptance test: Phase 9a (Inversive-Distance) as first new client
CLAUDE.md updated with a compact Phase 8 decision table.

chore: translate all German text to English across code, docs, and CI
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) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |

Math / code: - layout.hpp: add explanatory comment for Möbius deck transformation (from_three with z1=w1, z2=w2 encodes T fixing cut-edge endpoints) - layout.hpp: document spherical holonomy limitation — Vector2d stores only (x,y) of 3-D position diff; full SO(3) representation deferred Gradient sign convention (CLAUDE.md was wrong): - Euclidean and Spherical both use G_v = Θ_v − actual (target minus actual) - HyperIdeal uses G_v = actual − Θ_v - Hessian sign differs: Euclidean PSD, Spherical NSD → −H, HyperIdeal PSD Test counts (were inconsistent across all files): - Actual: 176 CGAL tests, 2 GTEST_SKIP (not 173/170/174, not 1 skip) - The 2 skips are EuclideanFunctional + SphericalFunctional Hessian gradient checks (Java @Ignore ports) — not HyperIdeal Hessian as previously stated - doc/api/tests.md: add missing SmokeEuclidean suite (3 tests), EuclideanLayout (2), SphericalLayout (1), fix GaussBonnet 8→12, MeshIO 9→6, Layout 8→6, EuclideanFunctional 11→12, HomologyGenerators no longer a GTEST_SKIP stub (live test on brezel2.obj) - doc/roadmap/phases.md: Phase 7 cumulative 158→176 tests - doc/roadmap/phases.md: Phase 3 clarified — HyperIdeal Hessian is FD - CLAUDE.md: suite count 28→34, test ref 173+36→174+36 - scripts/try_it.sh: expected output 173/1 skipped → 174/2 skipped CI table (CLAUDE.md): - test-cgal now triggers on pull requests only (not main/dev pushes) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> |

test/docs: Scalability Smoke Tests + Komplexitätsdokumentation
test_scalability_smoke.cpp (3 neue Tests → 176 CGAL-Tests gesamt):
SmokeEuclidean.CatHead_SmallOpen — V=131, Newton 3 iter, <1ms
SmokeEuclidean.Brezel_LargeGenus2 — V=6910, Newton 3 iter, 69ms (Apple M)
SmokeEuclidean.Brezel2_Genus2_CutGraph — V=2622, Cut Graph 10ms, 4 Nähte
- Korrektheit-Assertions (iter<30, ||G||<1e-8), kein Timing-Assert (CI-stabil)
- Informative Ausgabe: iter, Residuum, Laufzeit als stdout-Print
- Korrektur: brezel.obj ist Genus-2 (χ=−2), nicht Genus-1 (Namensgebung
aus Java-Original übernommen, nicht topologisch)
- Perturbation x0=−0.05 damit Newton tatsächlich iteriert
doc/math/complexity.md (neu):
- O()-Analyse aller Pipeline-Schritte tabellarisch
- Gemessene Timings auf echten Meshes (Apple M, Release, Single-Thread)
- HyperIdeal-FD-Hessian als bekannter Bottleneck dokumentiert
- Skalierungsprojektion bis V=100K
- Speicherverbrauch-Tabelle
- Reproduzierbare Messanleitung
README.md + CLAUDE.md: Testzähler 173→176, complexity.md verlinkt

docs: Konzeptdokument Declarative YAML Pipeline (Phase 8e)
doc/concepts/declarative-pipeline.md — vollständige Design-Spezifikation:
1. Kernidee: Processing Units mit expliziten require/provide-Contracts
2. Token-Vokabular: 30 Tokens in 7 Kategorien
input, setup, Gauss-Bonnet, solver, topology, layout, period/domain/output
3. YAML-Schema: Vollständige Syntax inkl. Parameterdefaults aller Units
4. Validierungsalgorithmus: monoton wachsendes provided-Set, Pre-Execution-Check
5. 5 vollständige Beispiele:
A — Euklidische Uniformisierung Torus (τ-Ausgabe)
B — Sphärische Uniformisierung (cathead.obj)
C — Hyperbolische Uniformisierung Torus (Poincaré-Disk)
D — Volle Pipeline mit Periodenmatrix + 5×5-Kachelung
E — Absichtlich fehlerhaftes Beispiel mit Validator-Fehlermeldungen
6. C++-Mapping: alle YAML-Unit-Namen → C++-Funktionen + Header
7. Implementierungsplan (Phase 8e): pipeline.hpp + CLI-App + YAML-Abhängigkeit
8. Design-Entscheidungen: YAML vs. JSON/TOML, explizit vs. auto-inference,
linear vs. DAG, eine Geometrie pro Datei
