Service, not source identity
GitHub can host the repository and coordinate review. Git remains the version-control system; the service is one possible collaboration environment. Node identities must not depend on GitHub URLs.
Useful leverage
Pull requests can gather human review and automated checks for generated changes. Actions can validate the graph and build the site before deployment. Prefer least-privilege permissions and review workflow changes as executable code. Do not expose repository secrets to untrusted contributions or AI context.
No GitHub repository, remote, or workflow is automatically provisioned by this site. Choosing the service and publishing source are separate decisions.
