GitHub Docs required signed commits squash merge unsigned commits pull request branch protection
💡 Result:
GitHub’s docs confirm that **requiring signed commits can block a squash merge even when GitHub would sign the final squash commit**. GitHub checks the commits introduced by the pull request, including commits on its head branch; any unsigned commit can prevent the merge. ([docs.github.com](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches?ref=jessehouwing.net&utm_source=openai))
To unblock it, **rewrite and sign the unsigned commits on the PR branch**, then force-push the rewritten branch. Alternatively, someone with permission to bypass the protection can merge it. ([docs.github.com](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches?ref=jessehouwing.net&utm_source=openai))
That’s distinct from pushing directly to the protected branch: required signing also means commits pushed there must be signed and verified. ([docs.github.com](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets?ref=jscarle.dev&utm_source=openai))

Do not require a new pull request after signing the branch.
Required signed commits can block squash merging when the pull request contains unsigned commits. Contributors can rewrite and sign the existing pull-request branch, then force-push it. A new pull request is not required.
Suggested fix
- Re-create such a branch with signed commits (`git cherry-pick -S`) and open a new PR.
+ Rewrite the existing PR branch with signed commits, then force-push it.
+ Opening a new PR is not required.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Adds a Signed commits section to this repo's CONTRIBUTING, per owner ruling D218. The estate policy is
docs/SIGNING-POLICY.adocin hyperpolymath/standards.This repo's default branch is covered by the zero-bypass
Require-Signed-Commitsruleset, and rebase-merge is off. The section tells contributors what that requires:If the file already had its own signing section, that section is replaced in place instead of adding a second one. Lines elsewhere that told people to sign with GPG are changed to match the policy (SSH for people).
This is a docs-only change. The commit was created through
createCommitOnBranch, so GitHub signs it.🤖 Generated with Claude Code
