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 guidance on commit-signing requirements, approved signing methods, and merge practices.
    • Documented how to recreate a branch with signed commits when needed.

Walkthrough

CONTRIBUTING.adoc adds a “Signed commits” section. It describes signing requirements, signing methods, and merge guidance.

Changes

Contribution guidance

Layer / File(s) Summary
Signed commit requirements
CONTRIBUTING.adoc
Adds guidance on signed commits, signing methods for different contributor types, unsigned-commit merge blocks, squash merges, and signed cherry-picks.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Suggested reviewers: metadatastician

Merge Risk: 🟡 Moderate · up to af7c8

Contributors may receive conflicting signing instructions or create commits that do not follow the SSH guidance, and may open an unnecessary PR. Align the signing guidance and recovery steps before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to af7c8

This change documents signing and merge requirements without changing their enforcement. Another contributor guide still specifies GPG signing rather than SSH signing, and the externally managed admission controls were not independently verified. No introduced security bypass was established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The directly affected audience is repository contributors and automation following this guide. The inspected change does not grant new repository privileges or alter application, tenant, credential, or data-store access.

Trust Boundaries and Controls

  • observed — The guide distinguishes contributor-held SSH signing identity from GitHub-generated signatures for automated API commits. It attributes default-branch admission to an external ruleset; the inspected source does not establish the effective permissions, identity checks, or bypass configuration of that enforcement boundary.

* **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.

Align the contributor guides on commit signing.

CONTRIBUTING.adoc:58-62 directs people and interactive agents to use GitHub-registered SSH signing keys. However, docs/contributing.adoc:17-19 still tells contributors to configure a GPG signing key, and docs/contributing.adoc:52-53 requires GPG-signed commits. These current instructions give contributors different signing policies. Update the GPG references to match the SSH policy.

Suggested fix
-GPG signing key configured
+SSH signing key configured on GitHub

-All commits must be GPG-signed (CI enforces)
+All commits must be signed according to the SSH signing policy

not just the result, so one unsigned commit blocks the merge. Re-create such a

🌐 Web query:

site:docs.github.com update existing pull request branch force push rewritten commits signed commits required signatures

💡 Result:

If you mean **rewriting commits on an existing PR’s head branch**, GitHub’s docs say required-signature rules accept only commits that are signed and verified; if rewritten commits are unsigned, sign them and force-push the rewritten 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))

Whether the force-push itself is allowed is a separate rule: protected branches block force-pushes by default unless permitted, and allowing them doesn’t override other protections. ([docs.github.com](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches?ref=the-mergify-blog&utm_source=openai))

So: **sign the rewritten commits, then force-push only if the PR branch’s rules allow it.** The docs establish these requirements, but don’t give one universal command for updating every existing PR branch.

Update the existing PR when force-pushes are allowed.

The repository does not require a new PR after recreating signed commits. GitHub can update the existing PR when its branch permits force-pushes. Keep a new PR as the fallback when force-pushes are blocked.

Suggested wording
-  branch with signed commits (`git cherry-pick -S`) and open a new PR.
+  branch with signed commits (`git cherry-pick -S`) and force-push it to update
+  the existing PR when the branch permits force-pushes; otherwise open a new PR.

official Git documentation git-config gpg.format default openpgp git cherry-pick -S

💡 Result:

Yes. Git’s official docs state that `gpg.format` defaults to `openpgp`, and `git cherry-pick -S` (`--gpg-sign`) signs the resulting commit. ([git-scm.com](https://git-scm.com/docs/git-config?utm_source=openai))

So, unless configured otherwise, `git cherry-pick -S <commit>` uses OpenPGP signing. The `-S` is for signing; `-s` is a separate option that adds a `Signed-off-by` trailer. ([git-scm.com](https://git-scm.com/docs/git-cherry-pick?c=15OneBitJRx&utm_source=openai))

Configure SSH signing before the recovery step.

git cherry-pick -S requests a signature but does not select SSH signing. Git defaults to OpenPGP unless gpg.format=ssh is configured. The guidance lists the required settings but does not tell contributors to apply them. Without that setup, the command may create an OpenPGP-signed commit or fail when GPG is unavailable.

Add explicit setup commands before recommending the recovery command:

Suggested fix
 * **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.
+  Set these values before using `git cherry-pick -S`:
++
+[source,bash]
+----
+git config --local gpg.format ssh
+git config --local user.signingkey <key>.pub
+git config --local commit.gpgsign true
+----
 * **Apps, bots and workflows** never `git push` local commits. They write

Review comment at @CONTRIBUTING.adoc at line 68:
Update the SSH signing guidance near the recovery instruction to provide
explicit Git configuration commands for gpg.format, user.signingkey, and
commit.gpgsign before recommending git cherry-pick -S. Keep the existing
signing-key and verified-email requirements intact.
