- Line 117: Update the SSH signing guidance near `user.signingkey` to state that
the matching private key must be available through `ssh-agent` when the
public-key path is configured, and mention using the private-key path as an
alternative. Preserve the existing signing configuration and verified-email
guidance.

Git documentation gpg.format ssh user.signingKey public key file ssh-agent private key signing commits
💡 Result:
For SSH-signed commits, Git’s documentation says:
- Set `gpg.format` to `ssh`.
- `user.signingKey` can be the **path to a private SSH key**, or a **public key** when the matching private key is available through `ssh-agent`. You can also set it directly as `key::ssh-ed25519 ...`. ([git-scm.com](https://git-scm.com/docs/git-config?utm_source=openai))
Example using a public-key file and agent:
```sh
git config --global gpg.format ssh
git config --global user.signingKey ~/.ssh/id_ed25519.pub
git config --global commit.gpgSign true
```
The private key must be loaded in `ssh-agent`. If `user.signingKey` is unset, Git can try `gpg.ssh.defaultKeyCommand` (for example, `ssh-add -L`) to find a key. ([git-scm.com](https://git-scm.com/docs/git-config?utm_source=openai))

State the SSH private-key requirement.
With user.signingkey=<key>.pub, Git requires the matching private key to be available through ssh-agent. Add this requirement, or configure user.signingkey with the private-key path.
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.
+ `commit.gpgsign=true`). The matching private key must be loaded in
+ `ssh-agent`. Alternatively, set `user.signingkey` to the private-key path.🤖 Prompt for AI Agents

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
