GitHub Docs update existing pull request by pushing commits to its head branch force push rewritten commits
💡 Result:
Yes. An open pull request tracks its **head branch**, so pushing new commits to that branch updates the PR. If you rewrote commits already pushed, GitHub’s docs say to force-push the rewritten history; for safety, use `--force-with-lease`:
```bash
git push --force-with-lease origin YOUR-BRANCH
```
This assumes `origin` is the remote containing the PR’s head branch. The push may be blocked if branch protection disallows force pushes. ([docs.github.com](https://docs.github.com/en/pull-requests/how-tos/commit-changes/changing-a-commit-message?utm_source=openai))

🌐 Web query:
https://github.com/hyperpolymath/standards/blob/main/docs/SIGNING-POLICY.adoc
💡 Result:
This document sets a policy that **every commit reaching a default branch must be signed**. It prescribes GitHub’s web-flow GPG signing for apps, bots, and workflows that write through GitHub’s API; humans and interactive agents use a registered SSH signing key. It also says rebase merges, certain contents-API commits, and workflow `git push` commits can be unsigned, and recommends squash merges or the estate’s `signed-push` action instead. ([github.com](https://github.com/hyperpolymath/standards/blob/main/docs/SIGNING-POLICY.adoc))
The page says the policy was set by owner rulings **D215–D218 on September 30, 2026**, and supersedes the sequencing in D90. It also provides setup commands for registering an SSH signing key and configuring Git. ([github.com](https://github.com/hyperpolymath/standards/blob/main/docs/SIGNING-POLICY.adoc))

Update the existing pull request after rewriting commits.
Re-create the branch with signed commits, then force-push it to the existing pull request's head branch. GitHub updates the pull request and its checks. Open a new pull request only if branch policy prevents the force-push.

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
