Pin every `uses:` ref in .github/workflows and composite actions to a
full 40-character commit SHA, with the original tag preserved as a
comment, e.g.
uses: actions/checkout@11bd719 # v4
Tags and branches are mutable; commit SHAs are not. Pinning to a SHA
closes a supply-chain vector where a compromised action could replace
what runs in CI without changing the tag we reference.
Generated mechanically with `pinact run`
(https://github.com/suzuki-shunsuke/pinact). No version bumps were
applied (strict pin).

Summary
Pin every
uses:ref in.github/workflows/(and any composite actionfiles) to a full 40-character commit SHA, with the original tag
preserved as a
# vXcomment.Why
Tags and branches are mutable, so a compromised action can replace what
runs in our pipelines without changing the tag we reference. Pinning to
a SHA closes that supply-chain vector. See GitHub's hardening guide:
https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions.
Deadline
TechOps is enforcing SHA-pinned GitHub Actions across the org.
Merging this PR brings the repo into compliance; workflows that still
reference mutable tags or branches may be blocked from running.
How
Generated mechanically with
pinact run.No version bumps were applied (strict pin); follow-up upgrades can come
from Renovate or a separate
pinact run -uPR.Test plan
Note
Low Risk
Mechanical CI hardening with no application or runtime behavior changes; pins lock existing action versions rather than bumping them.
Overview
Pins every third-party and MetaMask
uses:reference under.github/workflows/to a full commit SHA, with the prior tag noted in a# vXcomment. No action version upgrades—same releases as before, just immutable refs.Coverage spans build/lint/test, main (actionlint, release detection), create-release-pr, publish-release (artifacts + npm publish), publish-preview (
actions/checkout, checkout-and-setup v2), and security-code-scanner.Reviewed by Cursor Bugbot for commit 2e6f50d. Bugbot is set up for automated code reviews on this repo. Configure here.
