Summary
Pin all third-party GitHub Actions to full-length commit SHAs to prevent supply chain attacks.
Addresses findings from the
third-party-action-not-pinned-to-commit-shaSemgrep rule.Test plan
Note
Low Risk
Low risk: workflow-only changes that pin action references; main risk is CI/release breakage if a pinned SHA is incorrect or later removed upstream.
Overview
Pins previously tag-based third-party GitHub Actions in
manual-publish.ymlandrelease-please.ymlto specific commit SHAs (notablyrelease-please-actionandgh-action-pypi-publish) to reduce GitHub Actions supply-chain risk.Adds inline version comments for the pinned actions; no functional build/release logic changes beyond the pinned references.
