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.
