CI failure: Homebrew/actions/setup-homebrew@master no longer resolves in smoke.yml

[claude]

Summary

The Smoke Test CI workflow (.github/workflows/smoke.yml) fails at the Set up job step of the Linters (and Build) jobs:

##[error]Unable to resolve action `homebrew/actions@master`, unable to find version `master`

• Run ID: 34881594062
• Branch: fix/just-plugin-audit-exit-message
• Commit: 54e0e33
• PR: fix(just): stop plugin audit/prune findings reading as recipe crashes #419

Root cause

Homebrew removed the master branch alias from the Homebrew/actions repository; the default branch is now main. Every Homebrew/actions/setup-homebrew@master reference therefore fails to resolve before any job step runs. benchmarks.yml already uses @main, so this reference was simply left stale.

Fix

Pin the action to @main in smoke.yml (two occurrences, lines 31 and 57):

-        uses: Homebrew/actions/setup-homebrew@master
+        uses: Homebrew/actions/setup-homebrew@main

The same stale @master reference also exists in sbom.yml, coverage.yml, and claude.yml and will break those workflows identically — worth updating in the same change.

Why this could not be auto-fixed

I prepared and committed the fix locally, but pushing it was rejected:

! [remote rejected] ... (refusing to allow a GitHub App to create or update workflow `.github/workflows/smoke.yml` without `workflows` permission)

The CI auto-fix bot's token lacks the workflows permission required to modify files under .github/workflows/. A maintainer (or a token with workflows scope) needs to apply and push the one-line change.

Suggested labels

bug, ci-failure

Duplicate of #414. Fixed by #430 (43fd03d), which changes all five Homebrew/actions/setup-homebrew@master references to @main (smoke.yml Linters and Build jobs, coverage.yml, sbom.yml, claude.yml). Setup Homebrew passes on main at be2fd3b: https://github.com/laurigates/dotfiles/actions/runs/35738657555. Pinning the ref to a release SHA is tracked in #416.
