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 requiring signed commits to reach the default branch, including signing options for contributors and automated workflows.
    • Explained how to recreate a pull request branch containing unsigned commits and noted that squash merging is required.

Walkthrough

Both contribution guides add signed-commit requirements, instructions for people and automated committers, and guidance on merging pull requests with unsigned commits.

Changes

Signed commit guidance

Layer / File(s) Summary
Signing and merge guidance
CONTRIBUTING.adoc, .github/CONTRIBUTING.md
Both guides explain signing requirements and methods for people, interactive agents, apps, bots and workflows. They describe squash-merging pull requests, replacing branches with unsigned commits, and the disabled rebase-merge option.

Priority: ⬇️ Low

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

Change: Other

Merge Risk: 🔵 Low · up to 5cd7b

The signing instructions may fail for contributors whose private key is not available to Git, and the rebase-merge guidance conflicts with the checked-in setting. These are localized issues; align the guidance and configuration before relying on the policy.

Architecture Summary

Architecture risk: 🔵 Low · up to 5cd7b

The change affects 1 system.

Changed systems: CONTRIBUTING.adoc

No architecture-level concerns identified.

Review details

Systems and components

  • observed — CONTRIBUTING.adoc (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in CONTRIBUTING.adoc: Adds signed-commit requirements and instructions: people and interactive agents use a GitHub-registered SSH signing key and verified committer email; apps, bots and workflows create commits through the API rather than pushing local commits. Pull requests must be squash-merged because the ruleset checks every branch commit; unsigned commits block merging, and rebase-merge is disabled.
  • observed — Modified behavior in .github/CONTRIBUTING.md: Adds signing requirements and instructions for people, interactive agents, apps, bots and workflows, plus squash-merge guidance for PRs with unsigned commits and a statement that rebase-merge is disabled.

Review comments at @.github/CONTRIBUTING.md:
- Line 132: Update the SSH signing-key guidance in both contributor guides to
state that using a public-key path for user.signingkey requires the matching
private key to be available through ssh-agent, and that user.signingkey can
instead point to the matching private-key path.
- Line 140: Set the repository’s allow_rebase_merge setting to false so
rebase-merge is disabled, matching the contribution guides.

Review comments at @CONTRIBUTING.adoc:
- Line 77: Change the “Signed commits” heading to level 2 so it remains nested
under “Contributing to systemet” and matches the document’s existing section
hierarchy.

official Git documentation gpg.format ssh user.signingkey public key ssh-agent private key path

💡 Result:

The official Git documentation says that with `gpg.format=ssh`, `user.signingKey` can be the **path to a private SSH key**, or a **public key** when the private key is available through `ssh-agent`. You can also set it directly to a public key prefixed with `key::`. ([git-scm.com](https://git-scm.com/docs/git-config?utm_source=openai))

```ini
[gpg]
    format = ssh
[user]
    signingKey = ~/.ssh/id_ed25519.pub
```

If `user.signingKey` is unset, Git can run `gpg.ssh.defaultKeyCommand` to find a key; the docs give `ssh-add -L` as an example. ([git-scm.com](https://git-scm.com/docs/git-config?utm_source=openai))

Document the SSH signing-key prerequisite.

Both guides use a public key path for user.signingkey, but Git requires the matching private key to be available through ssh-agent. A contributor without that access can fail to create signed commits. Git also supports setting user.signingkey to the private-key path.

Add this prerequisite and alternative to both guides:

Suggested documentation update
 -  as a *signing* key (`gpg.format=ssh`, `user.signingkey=<key>.pub`,
    `commit.gpgsign=true`). The committer email must be verified on that account.
+  When `user.signingkey` points to a public key, the matching private key must
+  be available through `ssh-agent`. Alternatively, set `user.signingkey` to the
+  matching private-key path.

Update the SSH signing-key guidance in both contributor guides to state that
using a public-key path for user.signingkey requires the matching private key to
be available through ssh-agent, and that user.signingkey can instead point to
the matching private-key path.

Comment thread .github/CONTRIBUTING.md
- 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.
Rebase-merge replays commits unsigned and is disabled.

GitHub rulesets require signed commits pull request every commit source branch semantics official documentation

💡 Result:

**Yes—when the rules target the PR’s base branch.** GitHub’s signed-commits rule checks the commits introduced by the pull request, including commits on its head/source branch. An unsigned source-branch commit can therefore block merging—even for a squash merge, though GitHub signs the resulting squash commit. The commits need valid, verified signatures. ([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))

The two rules do different things:

- **Require signed commits:** requires qualifying commits to be signed and verified.
- **Require a pull request:** requires commits to be made on a non-target branch and submitted through a pull request before merging. It does **not**, by itself, mean every source-branch commit must be signed. ([docs.github.com](https://docs.github.com/en/rest/orgs/rules?utm_source=openai))

**Scope nuance:** for rulesets, when a branch is *created*, GitHub checks only commits not accessible from other branches; when a branch is *updated*, it checks all commits in the update range—even if reachable elsewhere.

🌐 Web query:

site:docs.github.com ruleset required signed commits pull request commits protected branch

💡 Result:

GitHub’s rule is **Require signed commits** (available in both branch protection and rulesets). It requires commits being added to the protected branch to have verified signatures—including commits introduced through a pull request. ([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))

A key wrinkle: GitHub checks the commits introduced by the pull request, so **unsigned commits on the PR branch can block merging—even for a squash merge, where GitHub would sign the resulting commit**. The usual fix is to rewrite and sign the unsigned commits, or have an authorized person bypass the rule. ([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))

Disable rebase-merge in the repository settings.

.github/settings.yml requests rebase-merge, while both contribution guides state that it is disabled. An active Require-Signed-Commits ruleset can reject unsigned commits introduced by a pull request, but that does not disable the rebase-merge method. Set the option to false.
