🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not require signed commits on the PR branch for squash merges.
GitHub creates a new squash commit on the protected default branch. The branch commits are not themselves the commits that reach the default branch. Therefore, the statement that one unsigned branch commit blocks a squash merge is incorrect for this repository's squash workflow and can make contributors recreate branches unnecessarily.
Change only the affected sentence:
Suggested fix
- 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.
+ GitHub signs the squash commit that reaches the default branch, so commits on the PR branch do not need individual signatures for a squash merge.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

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
