## Signed commits

Every commit that reaches the default branch must be signed; a ruleset refuses
unsigned pushes. Estate policy:
[SIGNING-POLICY](https://github.com/hyperpolymath/standards/blob/main/docs/SIGNING-POLICY.adoc).

- **People and interactive agents** sign with an SSH key registered on GitHub
as a *signing* key (`gpg.format=ssh`, `user.signingkey=<key>.pub`,
`commit.gpgsign=true`). The committer email must be verified on that account.
- **Apps, bots and workflows** never `git push` local commits. They write
through the API (`createCommitOnBranch` or the estate `signed-push` action)
so that GitHub signs each commit.
- Merge PRs with **squash**. The ruleset checks every commit on the PR branch,
not just the result, so one unsigned commit blocks the merge. Re-create such a
branch with signed commits (`git cherry-pick -S`) and open a new PR.

🌐 Web query:

site:github.com/hyperpolymath/standards "force push" OR "force-push" signed commits

💡 Result:

I couldn’t find a matching `hyperpolymath/standards` result for **“force push” / “force-push”** alongside **signed commits**. The search results surfaced GitHub’s general documentation instead, which says that a branch can require signed commits and separately allow or block force pushes; allowing force pushes doesn’t override other branch rules. ([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))

That doesn’t establish whether the repository itself contains a relevant policy or discussion—the search may not index all of its files or issues.

Keep the existing PR when replacing unsigned commits.

Opening a new PR is not always required. When force-pushes to the source branch are permitted, rewrite and sign the commits, then force-push the branch to the existing PR. Otherwise, open a new PR.

Suggested wording 
- branch with signed commits (`git cherry-pick -S`) and open a new PR.

Review comment at @.github/CONTRIBUTING.md at line 137:
Update the unsigned-commit guidance around `git cherry-pick -S`: when
force-pushes to the source branch are permitted, instruct contributors to push
the rewritten signed commits to the existing PR; otherwise, instruct them to
open a new PR.
