Diff is fine; it's stuck because no check has reported on the current head

The change itself is a clean one-line SHA-pinned digest bump and it merges into current main without conflict:

$ git merge-tree --write-tree main pr1101   # no conflict

-        uses: Homebrew/actions/setup-homebrew@c722b5d961eb7f3ebec81ec2e5584faf7c3cff5d # main
+        uses: Homebrew/actions/setup-homebrew@3b81d438eda92ee13b5849940d993be027717ecf # main

Still SHA-pinned with the # main comment intact, so the supply-chain posture is unchanged. Only .github/workflows/validate-brewfiles.yaml is touched — nothing under system_files/, so no image blast radius.

Why it isn't merging: mergeable_state is blocked and there are zero reported checks on head 905cd33:

$ pull_request_read get_status 1101
{"state":"pending","sha":"905cd33...","total_count":0,"statuses":[]}
$ pull_request_read get_check_runs 1101
{"total_count":0,"check_runs":[]}

The automerge label can't fire while required checks are pending-and-absent, so this will sit indefinitely without a nudge.

Two contributing details worth a maintainer's eye:

1. There is a second, non-Renovate commit on this branch. 905cd33 ci: retry transient failing checks sits on top of caeb02c chore(deps): update homebrew/actions digest to 3b81d43. Renovate treats a branch with commits it didn't author as modified and generally stops rebasing it, which means this PR will also not self-update as main moves (its base is dff365d; main is now 56d81ef). If that commit was only meant to re-trigger CI, the cleaner path is ticking the rebase checkbox in the PR body and letting Renovate recreate the branch.
2. The workflow this edits is path-filtered, so pushing an unrelated empty-ish commit is not a reliable way to re-trigger it. A workflow_dispatch / re-run from the Actions tab is more likely to produce the missing check.

Nothing here needs changing in the diff — it just needs a check to actually run.
