  3. Partial: Has some implementation but missing key features

  4. Examples: get_pool_stats(), _calculate_piece_priority(), create_index_entry()

  5. Simplified: Works but uses simplified logic instead of full implementation

  7. Stub: Testing-only implementations

  8. Examples: _send_extended_handshake(), _fetch_metadata_from_peer()

Priority Areas for Implementation

  1. High Priority:
  2. Connection attempt tracking for metrics
  3. File verification implementation
  4. ML model integration for peer selection

  5. DHT network querying for address discovery

  6. Medium Priority:

  7. Piece availability tracking for prioritization
  8. Dynamic worker pool adjustment
  9. Time-based rate tracking

  10. Protocol compliance checking

  11. Low Priority:

  12. Testing stubs (if not needed for production)

  14. IPFS block extraction

Notes

  • Many "would" comments indicate future enhancements rather than critical missing functionality
  • Some methods work with simplified implementations but could be enhanced
  • Testing stubs are intentionally minimal and may not need full implementation
  • Some features may be implemented in related modules (e.g., DHT indexing in dht.py)
