No SSA-authored code, configuration, workflow, hostname, or secret exists anywhere in it. Of the eight branches, `patch-1` is SSA\u0027s contribution branch (YAML edits only) and the other six non-default branches are upstream feature branches inherited at fork time, authored 2015\u20132018 from non-SSA addresses.\n\nBecause the repository is a 2018 snapshot of a third-party (GitHub Inc.) codebase whose only surviving SSA-authored content is one YAML list line (`_data/governments.yml:701`, confirmed by blame), static-analysis, dependency, and secret-scan results it produces are upstream-attributable \u2014 see *Not filed* for the full disposition of all 33 scanner results. None represents an SSA vulnerability. The repository also is not deployed: `CNAME` names `government.github.com`, a GitHub-owned domain already bound to the upstream repository\u0027s own Pages deployment, and GitHub Pages will not bind the same custom domain to a second repository.\n\nFiled as Informational because dormant contribution forks under an agency GitHub organization create recurring false-positive load on organization-wide security scanning and expose the agency to supply-chain-alert fatigue for code it neither wrote nor operates.\n\nAdditional affected files (entire file): N/A \u2014 Informational",
