# Active Context

## Current Task
- Fixed model integration issues
- Updated code to match model categories
- Simplified classification system

## Recent Changes
1. SquareClassification.swift:
   - Exact category mapping:
     ```swift
     white_pawn, white_knight, white_bishop, white_rook, white_queen, white_king,
     black_pawn, black_knight, black_bishop, black_rook, black_queen, black_king
     ```
   - Default to empty square for unrecognized labels
   - Removed background variations from labels

2. PieceRecognizer.swift:
   - Using VNCoreMLModel consistently
   - Simplified error handling
   - Removed unnecessary piece counting
   - Using Vision framework for classification

## Next Steps
1. Test model integration:
   - Verify model loads correctly
   - Check classification accuracy
   - Monitor confidence levels

## Current Issues
Fixed:
- Model pipeline error
- Category mismatches
- Classification handling
