# Task 1 Summary: Fix Rust model scan to top-level only

**Status:** ✅ Complete
**Files Modified:**
- `tauri-app/src-tauri/src/model_files.rs`

## Changes Made

### 1. Added `scan_model_dir_top_level` function (lines 46-71)
A new function that scans only the immediate children of a directory (depth=1), returning only `.gguf` files without recursing into subdirectories.

### 2. Updated `scan_model_dir` to use top-level scan (lines 31-44)
Changed from calling `scan_model_dir_recursive` to calling `scan_model_dir_top_level` as the default behavior.

### 3. Kept `scan_model_dir_recursive` for future use (lines 73-97)
The recursive function is preserved with `#[allow(dead_code)]` annotation for potential future use cases.

### 4. Updated tests
- Renamed `scan_model_dir_finds_gguf_in_subdirectories` to `scan_model_dir_returns_only_top_level_gguf`
- Updated assertion to expect only top-level models
- Added new test `scan_model_dir_recursive_finds_nested_gguf` to verify the recursive function still works

## Verification

```bash
cd tauri-app/src-tauri && cargo test scan_model
```

All 5 tests pass:
- `scan_model_dir_filters_and_sorts_gguf_files` ✅
- `scan_model_dir_ignores_directories_named_like_models` ✅
- `scan_model_dir_skips_hidden_directories` ✅
- `scan_model_dir_recursive_finds_nested_gguf` ✅
- `scan_model_dir_returns_only_top_level_gguf` ✅

## Success Criteria Met

- ✅ `scan_models` Tauri command returns only `.gguf` files in the immediate directory
- ✅ Nested models in subdirectories are excluded from default scan
- ✅ Recursive scan function remains available for future use
- ✅ All existing tests continue to pass
