Conversation
Part of the CODE RED drill: limit what an attacker with GitHub write access, or a compromised third-party action, can do through CI. - Pin every third-party action to a full commit SHA (tag kept as a comment). - Dependabot: cover GitHub Actions and wait 14 days before proposing a new release (cooldown), per the supply-chain policy. - test-cloud-compilation: push the synced cloud-compilation branch as flink-sql-runner/pr-<number> instead of the PR's head ref, which a fork author controls (it could be main or develop).

What does this change?
CODE RED drill: shrink what an attacker with GitHub write access, or a compromised third-party action, can do through CI.
cooldown). This matches the CODE RED rule of not adopting releases under two weeks old.test-cloud-compilationpushed the synced branch into cloud-compilation (usingBOT_PAT) under the PR's own head ref, which a fork author chooses and which could bemainordevelop. It now always usesflink-sql-runner/pr-<number>. PRs that were synced before this change keep their old cloud-compilation branch, which is not cleaned up automatically.Area
How did you test it?
Only workflow, action and Dependabot config changed. Every file was parsed as YAML, and every pinned SHA was resolved from the tag with
git ls-remoteon 2026-11-03. CI on this PR exercises the pinned actions.Checklist
