Summary

Pin every uses: ref in .github/workflows/ (and any composite action
files) to a full 40-character commit SHA, with the original tag
preserved as a # vX comment.

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 -u PR.

Test plan

  • CI green on this branch

Note

Low Risk
CI-only pinning with no application or SIP validation logic changes; behavior should match the previously referenced v1 line.

Overview
Pins the Validate SIPs workflow’s MetaMask/action-checkout-and-setup step from the mutable @v1 tag to commit 392abd40aa6a0600a3c0ef4af75851662587e6ec, with # v1.4.0 kept in the comment so the intended release is still obvious.

This is a supply-chain hardening change only: checkout inputs (is-high-risk-environment: true) and the rest of the job are unchanged.

Reviewed by Cursor Bugbot for commit 241a04e. Bugbot is set up for automated code reviews on this repo. Configure here.

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).
