renovate-changeset.yml

name: Renovate Changeset

# Hosted Renovate (Mend) disables postUpgradeTasks and ignores
# allowedPostUpgradeCommands in repo config, so the runtime-dependency patch
# changeset can't be generated inside Renovate itself. We generate it here
# instead: Renovate labels `dependencies` bumps `runtime-deps` (see
# renovate.json), and this workflow commits `.changeset/renovate-dependencies.md`
# back to the PR branch so the bump flows through changesets into a real
# @datum-cloud/datum-ui release. devDependency-only PRs are never labelled and
# so intentionally get no changeset. (STRUCT-075 / CR-006)
