🌐 Web query:
site:docs.github.com commit signature verification SSH signing key verified email gpg.format user.signingkey
💡 Result:
GitHub’s docs confirm:
- For **SSH commit signing**, configure Git with:
```sh
git config --global gpg.format ssh
git config --global user.signingkey /PATH/TO/KEY.PUB
```
SSH signature verification requires Git 2.34 or later. ([docs.github.com](https://docs.github.com/en/authentication/managing-commit-signature-verification/telling-git-about-your-signing-key?platform=mac&s=09&utm_source=openai))
- GitHub marks a commit **Verified** when its GPG, SSH, or S/MIME signature can be cryptographically verified. ([docs.github.com](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification?utm_source=openai))
- The **verified-email matching requirement** in the docs applies to GPG keys: GitHub checks that the committer or tagger email matches an identity on the GPG key and is verified on the account. ([docs.github.com](https://docs.github.com/en/authentication/troubleshooting-commit-signature-verification/using-a-verified-email-address-in-your-gpg-key?ref=andrew-matveychuk&utm_source=openai))
So, `gpg.format` and `user.signingkey` are relevant to selecting an SSH signing key, while the cited verified-email rule is specifically about GPG.

Document the minimum Git version for SSH signing.
GitHub requires Git 2.34 or later for SSH commit signing. The guide does not state this requirement. A contributor using an older Git version can follow the listed settings but fail to create an SSH-signed commit. The ruleset can then reject the push as unsigned.
Suggested fix
- `<tool` `2>` v\`\<version\>\` — `<install` `instruction>`.

Adds a Signed commits section to this repo's CONTRIBUTING, per owner ruling D218. The estate policy is
docs/SIGNING-POLICY.adocin hyperpolymath/standards.This repo's default branch is covered by the zero-bypass
Require-Signed-Commitsruleset, and rebase-merge is off. The section tells contributors what that requires: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.🤖 Generated with Claude Code
