`reset()` and `step()` use the same lock to prevent concurrent access +2. **Memory Cleanup**: Old battles are cleaned up every 10 episodes +3. **Battle Cancellation**: Previous battle tasks are cancelled on reset +4. **Event Loop Bridge**: Proper async synchronization between FastAPI and poke-env loops +5. **State Validation**: Checks if battle is finished before allowing step() + +##
