+# Model Coverage
+
+This page is generated by comparing git-tracked model modules under `visdet/models/` against the upstream reference snapshot in `archive/mmdet/models/`.
+
+It is intended as a quick overview of what we have ported vs what remains from upstream.
+
+## Summary
+
+- The lists below are based on module filenames (not config availability).
+- `archive/mmdet/` is treated as read-only upstream reference.
