WalkthroughThe two contribution guides now state commit-signing requirements for commits reaching the default branch. They describe signing methods for people, interactive agents, apps, bots and workflows, and specify how unsigned commits and merge strategies affect pull requests. ChangesCommit-signing policy
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~5 minutes Change: Other Merge Risk: 🔵 Low · up to This documentation-only change describes signed-commit rules that the live ruleset enforces on the default branch. The statement that rebase-merge is disabled conflicts with the checked-in repository settings, and the repair guidance is unnecessarily heavy. Contributors may be confused, but nothing breaks. Fix the settings or wording before or soon after merge. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The change adds signing guidance without changing enforcement or granting new privileges. However, it claims rebase merging is disabled while the repository configuration enables it. This introduces an inaccurate security-policy expectation, not a demonstrated signature bypass.

GitHub rulesets require signed commits repair unsigned commits existing pull request branch force push
💡 Result:
Yes. GitHub checks **every commit introduced by the branch update**, so unsigned commits on an existing pull-request branch can block merging—even if the eventual squash commit would be signed. GitHub’s documented fix is to rewrite and sign those commits, then force-push the rewritten branch. ([docs.github.com](https://docs.github.com/en/enterprise-cloud%40latest/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets?utm_source=openai))
Typical workflow:
```bash
git fetch origin
git switch <pr-branch>
git config commit.gpgsign true # after configuring a signing key
git rebase -i --exec 'git commit --amend --no-edit -S' origin/<base-branch>
git push --force-with-lease
```
The rebase rewrites commit hashes; `--force-with-lease` updates the PR branch while helping avoid overwriting someone else’s newer push. **The force-push must be permitted** by the applicable rules: GitHub rulesets block force pushes by default unless configured otherwise or bypassed. ([docs.github.com](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets?utm_source=openai))
If the push is rejected, check which rulesets target the PR branch and whether force pushes are blocked. The exact applicable rules depend on your repository’s configuration.

site:docs.github.com/en/enterprise-cloud@latest/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets signed commits rewrite force push pull request
💡 Result:
GitHub’s **Require signed commits** ruleset blocks unsigned commits. To fix an unsigned commit, rebase to rewrite and sign the commit, then force-push the rewritten history. Pull requests can also be blocked if their head branch contains unsigned commits—even for a squash merge. ([docs.github.com](https://docs.github.com/en/enterprise-cloud%40latest/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets?utm_source=openai))
The page establishes that force-pushing is one way to publish the rewritten commits; it does **not** say that the ruleset itself requires or enables force pushes. The cited page is GitHub Enterprise Cloud’s `@latest` documentation, as returned by search.

Repair the existing pull request branch.
If a pull request branch contains unsigned commits, rewrite and sign those commits, then force-push the rewritten branch. The ruleset checks commits on the pull request branch, including squash-merge workflows. Opening a new pull request is not required.

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
