a2eee9c279 ci+quality: structural gates (CI: 3 new; local: 7 new + .clang-tidy)
Some checks failed
C++ Tests / test-fast (pull_request) Successful in 1m56s
API Docs / doc-build (pull_request) Successful in 58s
Markdown link check / check (pull_request) Successful in 45s
C++ Tests / test-cgal (pull_request) Failing after 13m14s
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.

0f78d181e1 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.
