name: Link check
# Gate every PR (and pushes to main) on the `lychee` Markdown link checker so
# broken internal anchors/relative paths and dead external URLs in README.md,
# Architecture.md, CONTRIBUTING.md, CHANGELOG.md, TODO.md, etc. don't rot
# undetected (moadim-io/daemon#431). Scope is limited to `**/*.md` — this is a
# docs gate, not a general crawler.
#
# Known-flaky/placeholder hosts (localhost, example.com) and transient
# failures (rate limits, timeouts) are handled by lychee.toml so the gate is
# signal, not noise; see that file for the documented ignore mechanism.
#
# The action is pinned to a full commit SHA (not a tag or `@v2`), consistent
# with spellcheck.yml's pinning of crate-ci/typos, so a new lychee release
# can't turn a green PR red without a visible SHA bump here.
#
# The weekly scheduled run exercises the gate against `main` on its own
# cadence, so external-link rot (a URL going dead months after the PR that
# added it) surfaces even without a docs-touching PR — mirroring
# spellcheck.yml's Monday cron.
