Summary
- Retuned futility pruning by increasing the base margin when the best move is known and scaling depth differently, allowing earlier cutoffs in quiet positions
- Updated the engine identity to “Revolution-dev v.2.20 090925 avx” across the codebase so GUIs and the UCI handshake display the new version string
Testing
- make build
- bash tests/perft.sh ./src/revolution_090925_v2.20_avx
