Built from Lichess cloud evaluations + local harvests. Each row is a position with an 8-wide soft move distribution (soft_indices / soft_probs) plus hard best move.

Fields

• board_array (64): piece encoding
• turn, castling, ep_square
• move_idx, cp, mate
• soft_indices[8], soft_probs[8]
• label_depth, phase, source, cache_name
