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 methods, and merge restrictions.

Walkthrough

The contribution guide now states the commit-signing requirements, signing methods for people and automation, and the merge requirements for pull requests.

Changes

Signed commit guidance

Layer / File(s) Summary
Signing and merge instructions
.github/CONTRIBUTING.md
Adds instructions for signing commits with a registered SSH signing key and verified committer email. It directs apps, bots and workflows to use the API or signed-push action. It also states that contributors must squash-merge, unsigned pull-request commits block merging, and rebase-merge is disabled.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Change: Other

Merge Risk: 🔵 Low · up to c5d79

The new instructions conflict with the existing mirror workflow, though they do not break it at runtime. Clarify their scope before merging to avoid confusion when maintaining that workflow.

Architecture Summary

Architecture risk: 🔵 Low · up to c5d79

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.

- Around line 132-138: Update the “Apps, bots and workflows” guidance so its
prohibition on pushing local commits applies to the GitHub default branch, not
mirror pushes. Keep the existing API and signed-push guidance focused on commits
intended for that branch.
