Adds a Signed commits section to this repo's CONTRIBUTING, per owner ruling D218. The estate policy is docs/SIGNING-POLICY.adoc in hyperpolymath/standards.

This repo's default branch is covered by the zero-bypass Require-Signed-Commits ruleset, and rebase-merge is off. The section tells contributors what that requires:

  • People and interactive agents sign with an SSH signing key.
  • Apps, bots and workflows write through the API, so GitHub signs their commits.
  • PRs are merged with squash.

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.

📝 Summary

Summary by CodeRabbit

  • Documentation
    • Added contribution guidance explaining commit-signing requirements, supported signing settings, and how to handle unsigned pull request branches.
    • Clarified that automated commits should use the approved API or estate action, and that pull requests must be squash-merged.

Walkthrough

The contribution guide now documents signed-commit requirements, signing configuration, commit creation methods, and merge instructions.

Changes

Commit signing guidance

Layer / File(s) Summary
Signing and merge instructions
.github/CONTRIBUTING.md
Adds signing instructions for people, interactive agents, apps, bots, and workflows. It specifies SSH settings, a verified committer email, API or estate-action commit creation, branch replacement for unsigned commits, and squash merging. It also states that rebase-merge is disabled.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Other

Merge Risk: 🔵 Low · up to f15ca

The signing wording could confuse contributors, and the recovery instructions require unnecessary review churn. Both are narrow documentation corrections; the change is otherwise mergeable.

Architecture Summary

Architecture risk: 🔵 Low · up to f15ca

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.

Architecture concerns
No architecture-level concerns identified.

🌐 Web query:

GitHub rulesets required signatures unsigned commits pushed require signed commits documentation distinguish signed pushes

💡 Result:

GitHub’s **“Require signed commits”** ruleset rule checks the **commits**, not whether the Git push itself is signed. Commits being added to the protected branch must have valid, verified signatures; unsigned commits can make the update or pull request merge fail. ([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))

So “unsigned commits pushed” is a useful shorthand, but the rule is not a signed-push requirement: authenticating a push to GitHub does not sign its commits. GitHub’s documentation describes commit-signature verification and does not establish a separate signed-push rule here. ([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))

site:github.com/hyperpolymath/standards SIGNING-POLICY.adoc required signatures signed commits unsigned pushes

💡 Result:

I couldn’t find `SIGNING-POLICY.adoc` in `hyperpolymath/standards` in the search results, so I can’t confirm what that file says about required signatures or unsigned pushes.

For comparison, GitHub’s documentation says that when a branch requires signed commits, pushes containing commits that aren’t signed and verified are rejected. ([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))

Refer to unsigned commits, not unsigned pushes.

“Signed push” can mean a signature on the push transaction. The ruleset checks commit signatures. Although the following bullet clarifies this, replace “unsigned pushes” with “pushes containing unsigned or unverified commits” to avoid ambiguity.

Suggested wording
-unsigned pushes. Estate policy:

- 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:

GitHub docs replace unsigned commits in pull request force push same branch required signatures

💡 Result:

Yes. GitHub’s docs say that if an unsigned commit blocks a pull request under required-signature rules, you should **rewrite and sign the unsigned commit(s) on the pull request’s head branch, then force-push the rewritten history to that branch**. ([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))

So the force-push goes to the **same branch the pull request uses**—not the protected base branch. The rewritten commits must have verified signatures. ([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))

Update the existing PR branch after signing its commits.

GitHub allows contributors to rewrite and force-push signed commits to the PR head branch. A new PR is not required. The documented squash-merge setting does not change this.

Suggested fix
-  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.

Update the signed-commit guidance in the contributing instructions to say
contributors can rewrite the PR branch with signed commits and force-push the
rewritten history to update the existing PR; remove the instruction to open a
new PR.
