Problem

Workflows reference third-party actions by mutable tags (actions/checkout@v6), so a moved or compromised tag changes what runs in CI and release jobs, including jobs with secrets and publish credentials. A few refs were already pinned, with only a major version in the comment.

Change

Every external uses: in .github/ now points at the full commit SHA of the latest release within its current major, with the full version as a trailing comment:

-uses: actions/checkout@v6
+uses: actions/checkout@d23441a48e516b6c34aea4fa41551a30e30af803 # v6.1.0

• Already-pinned refs were moved to the latest in-major release and their comments expanded to vX.Y.Z.
• expo/expo-github-action@v8 is pinned to 8.2.1. continuous-deploy-fingerprint@main only exists in 9.x, so it is pinned to 9.0.2, the same commit main points at today.
• dtolnay/rust-toolchain has no version tags, so both uses share one SHA with # stable.
• No major version bumps, no workflow logic changes.

Scope and approval

Small, mechanical CI hardening with no behavior change. Happy to open an issue or discussion first if preferred.

Verification

• Every external uses: matches @<40-hex> # vX.Y.Z (or # stable); checked with grep.
• Every SHA was resolved from the upstream repo's tag via the GitHub API.
• All workflow and action YAML files parse.
• Not run: CI itself, vp run check:changed (dependencies were not installed in this checkout).

Walkthrough

This change updates GitHub Actions references across shared CI setup and workflows. Many floating tags or branch references become commit-SHA pins. Some existing pins receive more specific release-version comments. The described workflow settings and logic remain unchanged.

The described step settings remain unchanged.
Mobile workflow action references .github/workflows/mobile-*.yml	Mobile build, preview, production, fingerprint, and screenshot workflows update action references. The described job configuration remains unchanged.
Release and publishing action references .github/workflows/release*.yml, .github/workflows/publish-aur.yml	Release and publishing workflows update action pins for checkout, artifacts, caches, toolchains, and publishing steps. Existing inputs and conditions described in the summaries remain unchanged.
Repository automation action references .github/workflows/issue-labels.yml, .github/workflows/pr-*.yml, .github/workflows/stale-needs-more-info.yml, .github/workflows/thread-transfer-report.yml	Issue and pull request automation workflows update action references.

Merge Risk: Minimal · up to 52053

This change pins GitHub Actions to commit SHAs without altering workflow logic. No concrete merge-blocking risk was found. CI was reportedly not run, which is normal residual uncertainty.

Full details: Title check

Explanation

The title "ci: pin GitHub Actions to full commit SHAs" matches the main change. The changeset replaces mutable tags such as @v6 with full commit SHAs across the .github/ workflows and action files, and the PR objectives describe the same change. It uses a conventional commit prefix and is concise.

Full details: Description check

Explanation

The description covers the problem, the change, scope, and verification. It explains why mutable tags are a risk and shows the before/after format. It also lists the special cases (expo-github-action, continuous-deploy-fingerprint, dtolnay/rust-toolchain) and the checks run and not run. It differs from the template in two ways. The Scope section does not link an issue, and it asks for an issue or discussion first, which the template does not require for a bug fix. The Verification section does not state an agent model, which the template asks for when an agent was used. These gaps are minor and do not change the assessment.

Dismissing prior approval to re-evaluate 5205325

[juliusmarminge]

The automated pipeline stopped on this pull request and will not merge it:

in the real app the problem is still there, and the rework changed nothing:

No change needed. The report says the problem still happens, but its own steps show the fix working: 141 mutable action references on base and zero on head out of 180 external uses, with checkout@v6 and both expo fingerprint@main references now 40-character SHAs. It ran no app or workflow and names no failing check or remaining mutable reference, so there is nothing to change. I re-checked against the latest origin/main: main has not changed .github since the branch's earlier merge, the branch merges cleanly (git merge-tree, no conflicts), and the merged tree has 0 mutable and 180 pinned external uses: references. The head stays at 5205325. AI-assisted; verified with the tests and tools listed above.

It stays open for a person to finish or close.

Thanks for this. Main already has the change, as of 05eff7f.

This change is already on main in 05eff7f, including the action pins, version comments, and explicit stable Rust toolchain input.

Your full change landed, so no replacement pull request or follow-up is needed for this scope.

Closing as superseded.
