The dev branch has been removed (trunk-based workflow: push to main, use
short-lived feature branches + PRs for risky/reviewable changes). These three
workflows still listed 'dev' as a push trigger — a dead reference now that the
branch is gone. Removed so the CI config matches reality.

Every container now has an explicit --memory limit so the OOM killer
has clean boundaries to work with instead of letting any single job
consume all available RAM:
test-fast: 800m (build Eigen+GTest, run 26 tests)
test-cgal: 2000m (LOW_MEMORY_BUILD, was already set)
quality-gates: 600m (apt install + 4 script checks)
doc-build: 800m (Doxygen HTML generation)
markdown-links: 400m (pure Python, very lightweight)
memory-swap = 1.5× memory in each case (150% total) so the OOM
killer fires cleanly without exhausting the SD card.
⚠ This is workflow-side protection only. The runner-side fix
(capacity: 1 in act-runner config) prevents parallel containers
entirely and is the more reliable protection — see CLAUDE.md.

The Pi runner (3-4 GB RAM, swap heavily loaded) OOMs when /ci-all
triggers test-cgal + quality-gates + doc-build + links simultaneously:
four Docker containers start at once after test-fast completes, each
consuming 150-400 MB, exhausting available RAM.
Fix: /ci-all removed from all three workflow files. Each keyword
now triggers exactly one job — no parallel container competition.
Safe workflow: one keyword per commit.
Typical sequence:
git commit -m 'fix: ... /test-cgal' → CGAL tests (~5 min)
git commit -m 'chore: /quality-gates' → style checks (~30 s)

issue_comment triggers had two problems: Gitea did not reliably fire
them, and the refs/pull/N/head checkout was fragile. Commit-message
keywords are simpler and guaranteed to work on any push event.
Trigger keywords (add anywhere in the commit message):
/test-cgal → CGAL test suite (277 tests, LOW_MEMORY_BUILD)
/quality-gates → license/codespell/shellcheck/cgal-conventions
/docs → Doxygen build + warning summary
/links → Markdown internal link check
test-fast still runs on every push (no keyword needed).
All `issue_comment` event handlers and `refs/pull/N/head` checkouts
removed from all three workflow files. review/** added to push branch
filters so this PR branch triggers normally.
CLAUDE.md CI table updated.
/test-cgal /quality-gates
Every CI job except test-fast and mirror-to-codeberg now runs only
when explicitly requested via a PR comment, instead of on every push
or PR sync. This keeps the Pi runner idle during WIP commits and lets
the author decide when to pay each job's cost.
Trigger commands:
/test-cgal → CGAL test suite (277 tests, ~5 min build + 31 s run)
/quality-gates → license/codespell/shellcheck/cgal-conventions (~30 s)
/docs → Doxygen build + warning summary (~2 min)
/links → Markdown internal link check (~10 s)
All comment-triggered jobs check:
event is issue_comment
AND comment is on a PR (issue.pull_request != null)
AND comment body contains the trigger word
AND checkout uses refs/pull/N/head (not the default branch)
Jobs that stay automatic:
test-fast — runs on every push (26 pure-math tests, < 5 s)
mirror-to-codeberg — unchanged
Jobs that keep additional triggers:
markdown-links — weekly cron (Mon 05:00 UTC) + workflow_dispatch
doc-build — workflow_dispatch (for manual runs outside a PR)
quality-gates drops `needs: test-fast` — it now runs independently
when comment-triggered (caller decides whether test-fast passed first).
CLAUDE.md CI pipeline table updated with all five jobs and their new
trigger descriptions.

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.
