ci.yml

# Version PRs from `changesets/action` use head branch `changeset-release/<base>` (e.g. `changeset-release/main`;
# see changesets/action `run.ts`: `versionBranch = \`changeset-release/${branch}\``).
#
# GitHub docs: required status checks may be successful, skipped, or neutral — skipped often still allows merge
# (see https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches#require-status-checks-before-merging ).
# This workflow still gates on `changeset-release/*` and finishes with one **`CI complete`** job so there is a
# single unambiguous pass/fail (branch protection also warns that duplicate job *names* across workflows can block merges).
