📝 WalkthroughWalkthroughA new GitHub Actions workflow is added to automatically push the main branch to the AUR (Arch User Repository) master branch. The workflow sets up SSH authentication, configures Git, and implements a push strategy with fallback retry logic using force-with-lease if the initial push fails. Changes

Pull request overview
This PR introduces automation for publishing the Aeth shell project to the Arch User Repository (AUR) via a GitHub Actions workflow. The workflow automatically pushes changes from the main branch to the AUR repository's master branch whenever code is merged to main.

The workflow triggers on every push to main, which means it will attempt to push to AUR even if the push doesn't contain changes to AUR-related files (PKGBUILD, .SRCINFO, etc.). Consider adding a path filter to only trigger when AUR-related files are modified, or adding a condition to check if relevant files have changed before pushing. This would avoid unnecessary AUR updates and potential confusion.

The git fetch aur master || true on line 40 silences fetch errors, but the subsequent --force-with-lease push on line 41 relies on having up-to-date remote refs. If the fetch fails, the force-with-lease push may not behave as intended (it could fail or force-push when it shouldn't). Consider removing the || true from the fetch command and handling the fetch failure explicitly, or adding a check to verify the fetch succeeded before attempting the force-with-lease push.

Using ssh-keyscan without verifying the fingerprint could expose the workflow to man-in-the-middle attacks. While this is common practice in CI/CD, consider hardcoding the known AUR host key fingerprint instead of dynamically scanning. You can obtain the official fingerprint from AUR documentation and add it directly to known_hosts for better security assurance.

In @.github/workflows/push-to-aur.yml:
- Around line 39-41: The fallback push currently does a `git fetch aur master`
followed immediately by `git push aur main:master --force-with-lease`, which
nullifies the lease protection; either make the intent explicit by changing the
push to an unconditional force (`git push aur main:master --force`) so the
fallback truly force-pushes, or preserve `--force-with-lease` safety by removing
the `git fetch aur master` step so the lease comparison uses the existing local
tracking ref (and handle the case where the runner has no tracking ref). Update
the commands accordingly around the `git fetch aur master` and `git push aur
main:master --force-with-lease` lines to reflect the chosen behavior.

7-10: Add apermissionsblock to follow the principle of least privilege.This workflow only needs to read repository contents. Without an explicit
permissionsblock, theGITHUB_TOKENreceives the repository's default permissions, which are often broader than necessary. Restricting permissions limits blast radius if the workflow or a dependency is compromised.🛡️ Suggested fix

11-17: Pin actions to commit SHAs instead of mutable version tags, and update webfactory/ssh-agent to latest.Both
actions/checkout@v4andwebfactory/ssh-agent@v0.8.1use mutable tags, which introduces supply-chain risk if a tag is compromised or force-pushed. GitHub's official security hardening guidance recommends pinning to full commit SHAs (e.g.,actions/checkout@692973e3d937129bcbf40652eb9f2f61becf3332 # v4.1.7).Additionally,
webfactory/ssh-agent@v0.8.1is outdated; the latest version isv0.9.1(released Mar 2025). Given GitHub's deprecation of Node 20 (effective Mar 4, 2026), upgrading to the latest release ensures compatibility with current and future runner defaults.

--force-with-lease immediately after git fetch offers no protection — it behaves like --force.
--force-with-lease guards against overwriting unknown remote changes by comparing the remote ref to the locally cached tracking ref. After git fetch aur master on Line 40, the local aur/master is updated to the current remote state, so the lease check always passes — making this equivalent to --force.
If the intent is a genuine force-push fallback, be explicit:
Suggested fix
echo "Regular push failed, fetching remote and attempting force-with-lease push"
- git fetch aur master || true
- git push aur main:master --force-with-lease
+ # Force push as fallback — regular push failed (e.g. history diverged).
+ # This is intentional for AUR sync where main is the source of truth.
+ git push aur main:master --forceIf you actually want the safety of --force-with-lease, do not fetch before the push so the lease comparison uses a stale (or absent) local ref. But note that on a fresh GitHub-hosted runner the tracking ref won't exist at all, so --force-with-lease without a prior fetch would also fail for a different reason.
