| 7 | |
| 8 | - test_repo_home_renders_file_tree_server_side |
| 9 | Seed a file tree entry via a commit object, assert filename in HTML. |
| 10 | |
| 11 | - test_repo_home_branch_picker_has_hx_get |
| 12 | Branch select form carries ``hx-get`` attribute pointing to repo base URL. |
| 13 | |
| 14 | - test_repo_home_htmx_fragment_on_branch_switch |
| 15 | GET with ``HX-Request: true`` → file tree fragment (no <html> wrapper). |

| 17 | - test_repo_home_shows_tempo_bpm |
| 18 | Repo with tempo_bpm set → BPM value appears in sidebar HTML. |
