| 1 | """Add composite (repo_id, name) index on musehub_branches. |
| 2 | |
| 3 | get_branch_head_commit_id() does a point lookup WHERE repo_id = ? AND name = ? |
| 4 | on every push and fetch. Without a composite index this scans all branches for |
| 5 | the repo. list_branches_with_detail() also benefits: the composite index covers |
| 6 | both the WHERE clause and the ORDER BY name, eliminating an in-memory sort. |
