| 5 | - test_forks_page_returns_200 — page renders without auth |
| 6 | - test_forks_page_no_auth_required — no JWT needed for HTML shell |
| 7 | - test_forks_page_has_svg_dag_markup — SVG DAG scaffold present in HTML |
| 8 | - test_forks_page_has_legend — divergence colour legend present |
| 9 | - test_forks_page_has_compare_button_js"Compare" action JS present |
| 10 | - test_forks_page_has_contribute_upstream_js"Contribute upstream" action JS present |
| 11 | - test_forks_page_json_response — ?format=json returns ForkNetworkResponse |
| 12 | - test_forks_page_json_has_root_and_total — JSON contains root and totalForks fields |
| 13 | - test_forks_page_json_children_present — fork children appear in JSON root.children |
| 14 | - test_forks_page_json_divergence_computed — divergence_commits field is non-negative int |
| 15 | - test_forks_page_unknown_repo_404 — unknown owner/slug → 404 |
| 16 | - test_forks_page_base_url_in_html — HTML uses owner/slug base URL pattern |
| 17 | - test_forks_page_json_empty_repo — repo with no forks returns total_forks=0 |
