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

[claude]

Summary

Smoke Test CI fails at the very first step (Set up job) of the Linters job with:

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

• Workflow: Smoke Test CI (.github/workflows/smoke.yml)
• Branch: fix/enable-github-actions-migration-plugins
• Run ID: 34770384899
• Commit: 2097bb0
• PR: fix(claude): enable github-actions-plugin and migration-patterns-plugin #413

Root cause

Homebrew/actions renamed its default branch from master to main and removed the master branch, so Homebrew/actions/setup-homebrew@master can no longer be resolved. The action reference is evaluated during Set up job, so both the Linters and Build jobs in smoke.yml fail before running any steps.

This same migration was already applied to benchmarks.yml in #175 (setup-homebrew@main), confirming @main is the correct pin.

Why this is not auto-fixed

The fix requires editing .github/workflows/smoke.yml, but the claude[bot] GitHub App token lacks the workflows permission, so the push is rejected:

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

This matches the limitation previously noted in #180.

Suggested manual fix

Change both occurrences in .github/workflows/smoke.yml (lines 31 and 57):

```diff

•    uses: Homebrew/actions/setup-homebrew@master
  

•    uses: Homebrew/actions/setup-homebrew@main
  

```

Same latent bug in other workflows

The following workflows still reference the removed @master branch and will fail identically when they next run — worth fixing in the same commit:

• .github/workflows/claude.yml (line 71)
• .github/workflows/coverage.yml (line 29)
• .github/workflows/sbom.yml (line 30)

(benchmarks.yml already uses @main.)

Suggested labels: `bug`, `ci-failure`

[laurigates]

Fixed by #430 (43fd03d), which changes the five Homebrew/actions/setup-homebrew@master references to @main: .github/workflows/smoke.yml (Linters and Build (Ubuntu) jobs), coverage.yml, sbom.yml and claude.yml. benchmarks.yml was already on @main. No setup-homebrew@master reference remains at be2fd3b.

@main resolves to 848c272, which is release 2026.09.21.1. Setup Homebrew passes on main at be2fd3b in Smoke Test CI (https://github.com/laurigates/dotfiles/actions/runs/35738657555), SBOM Generation (https://github.com/laurigates/dotfiles/actions/runs/35738657536), Test Coverage (https://github.com/laurigates/dotfiles/actions/runs/35738657485) and Performance Benchmarks (https://github.com/laurigates/dotfiles/actions/runs/35738657571). The claude.yml job has not executed since: its if: requires an @claude mention, and both runs triggered after #430 (e.g. 35728998800) were skipped. It uses the same ref string.

#430 carried no closing keyword, so this issue, #416 and the duplicates (#417, #420, #423, #425, #427, #429) stayed open. All eight were filed by the auto-fix workflow (laurigates/.github reusable-auto-fix.yml), which opens a new issue for each failed Smoke Test CI run on a PR without searching for an existing one; #416 and #417 came from two runs on the same PR (#415).

@main is still a branch ref. Pinning it to a release SHA is tracked in #416.
