+# Changes Summary - Data Comparison Logic Fix
+
+## Issues Fixed
+
+### 1. Removed All-Sheet Functionality
+- **Problem**: The tool was processing all sheets together, causing cross-sheet duplicate detection
+- **Solution**: Completely removed all-sheet functionality, now only processes one sheet at a time
+- **Changes**: 
+  - Replaced `extract_kst_coordi_items()` with `extract_kst_coordi_items_for_sheet(sheet_name)`
+  - Updated all comparison methods to work sheet-specifically
+
+### 2. Fixed Duplicate Detection Logic
+- **Problem**: Items appearing once on each side were incorrectly marked as duplicates
+- **Solution**: Fixed `_find_duplicates_in_list()` to only return items that actually appear multiple times
+- **Changes**: Used `Counter` to count occurrences and only return items with count > 1
+
+### 3. Implemented Mixed Duplicate Priority
+- **Problem**: Items showing as both pure duplicates and mixed duplicates
+- **Solution**: Mixed duplicates (items in both datasets with duplicates on one side) now take priority
+- **Changes**: Generate mixed duplicates first, then exclude those keys from pure duplicate lists
+
+### 4. Sheet-Specific Analysis Only
+- **Problem**: Cross-sheet contamination in duplicate detection
+- **Solution**: All analysis now happens within a single sheet context
+- **Changes**: 
+  - `get_comparison_summary()` now requires sheet filter and defaults to first sheet
+  - Removed old filtering methods, replaced with sheet-specific extraction
+
+## BA Confirmed Cases - All Working ✅
+
+### US URGENT Sheet
+- ✅ `금수의 영역 - Episode 17` → Coordi duplicate
+- ✅ `신결 - Episode 23` → Coordi duplicate  
+- ✅ `트윈 가이드 - Episode 31` → Mixed duplicate (exists in both, duplicates in Coordi)
+- ✅ No longer shows `트윈 가이드 - Episode 31` as pure Coordi duplicate
+
+### TH URGENT Sheet
+- ✅ `백라이트 - Episode 53-1x(휴재)` → KST duplicate (doesn't appear in Coordi)
+
+## Code Changes Made
+
+### data_comparator.py
+1. **New Methods**:
+   - `extract_kst_coordi_items_for_sheet(sheet_name)` - Sheet-specific extraction
+   - `categorize_mismatches_for_sheet(sheet_data)` - Sheet-specific categorization
+   - `generate_mismatch_details_for_sheet()` - Sheet-specific mismatch details with priority logic
+   - `group_by_title_for_sheet()` - Sheet-specific grouping
+
+2. **Updated Methods**:
+   - `_find_duplicates_in_list()` - Fixed to only return actual duplicates
+   - `get_comparison_summary()` - Now sheet-specific only
+   - `print_comparison_summary()` - Added sheet name to output
+
+3. **Removed Methods**:
+   - `extract_kst_coordi_items()` - Replaced with sheet-specific version
+   - `categorize_mismatches()` - Replaced with sheet-specific version
+   - `generate_mismatch_details()` - Replaced with sheet-specific version
+   - `group_by_title()` - Replaced with sheet-specific version
+   - `filter_by_sheet()` - No longer needed
+   - `filter_grouped_data_by_sheet()` - No longer needed
+   - `calculate_filtered_counts()` - No longer needed
+
+### web_gui.py
+- Updated matched items extraction to use new grouped data structure
+- Removed dependency on old `categorize_mismatches()` method
+
+### Test Files
+- `test_ba_confirmed_cases.py` - New test to verify BA confirmed expectations
+- `test_sheet_filtering.py` - Updated to work with new sheet-specific logic
+
+## Performance Improvements
+- Faster analysis since no cross-sheet processing
+- More accurate duplicate detection
+- Cleaner separation of concerns between sheets
+
+## Verification
+All tests pass:
+- ✅ Sheet filtering works correctly
+- ✅ Duplicate detection is accurate
+- ✅ BA confirmed cases match expectations
+- ✅ Web interface works properly
+- ✅ Mixed duplicates take priority over pure duplicates

 ## Comparison Logic
 
 The tool compares Excel data by:
-1. Finding columns by header names (not positions)
-2. Extracting title+episode combinations from both datasets
-3. Categorizing mismatches and calculating reconciliation
-4. Displaying results with reasons for each discrepancy
+1. **Sheet-specific analysis only** - No more "All Sheets" functionality, each sheet is analyzed independently
+2. Finding columns by header names (not positions)
+3. Extracting title+episode combinations from both datasets within the selected sheet
+4. **Fixed duplicate detection** - Only items that appear multiple times within the same dataset are marked as duplicates
+5. **Mixed duplicate priority** - Items that exist in both datasets but have duplicates on one side are prioritized over pure duplicates
+6. Categorizing mismatches and calculating reconciliation
+7. Displaying results with reasons for each discrepancy
+
+### BA Confirmed Cases
+- **US URGENT**: `금수의 영역 - Episode 17`, `신결 - Episode 23` (Coordi duplicates), `트윈 가이드 - Episode 31` (mixed duplicate)
+- **TH URGENT**: `백라이트 - Episode 53-1x(휴재)` (KST duplicate, doesn't appear in Coordi)
