ci: disable rebase-stack workflow in favor of gh native stack#443
Merged
Conversation
## Summary ### Why? We are moving stacked-PR management to GitHub's native stacked PR support. The custom `rebase-stack` workflow (which auto-rebases and retargets child PRs when a stacked PR merges) is no longer the intended mechanism, so it should stop running. ### What? Gates the `rebase-stack` job with `if: false` rather than deleting the workflow, so it never runs on PR merge while the file — including its full design docs and security setup — is preserved. Re-enabling is a one-line revert: restore the condition to `github.event.pull_request.merged == true`. The workflow is not a required check, and the only other references are documentation/allowlist entries in `.github/zizmor.yml` that remain valid since the file stays in place. Note: this workflow is the sole owner of merged-head-branch deletion and requires the repo setting "Automatically delete head branches" to be OFF. With it disabled, re-enable that repo setting to restore branch cleanup.
