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
CI-only pinning with no application or secret-handling logic changes; main risk is a mis-pinned SHA breaking a workflow run, not product behavior.
Overview
Replaces mutable version tags on third-party and MetaMask
uses:references with full commit SHAs, keeping the original tag in a# vXcomment for readability. Updates span build/test, release PR creation, docs publishing, and npm release workflows (actions/checkout,setup-node,cache, and MetaMask publish/release actions).This is a supply-chain hardening change only: workflow logic, secrets, and job graphs are unchanged; each step should run the same action code as before, just pinned immutably for org compliance.
