Conversation
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 workflow-only change with no application or release logic edits; behavior should match the previously referenced tag versions.
Overview
Replaces mutable
uses:refs (tags like@v4) with full commit SHAs across the main CI/release workflows, keeping the original version in a# vXcomment for readability.Affected workflows:
build-lint,create-release-pr,main,publish-gh-pages, andpublish-release. Third-party and MetaMask actions touched includeactions/checkout,actions/setup-node,action-create-release-pr,action-is-release,action-publish-gh-pages,action-publish-release, andaction-npm-publish. Step inputs, job graphs, and shell commands are unchanged—only how actions are resolved at runtime.This aligns the repo with org supply-chain hardening (immutable action content instead of retargetable tags).
