Entropy Modes

Deterministic Mode

• Manual dice sequence input
• No hidden runtime randomness
• Best for recovery and audit workflows

Hybrid Mode

• Combines dice entropy and system RNG.
• Good for creating new wallets with defense in depth.
• Not intended for exact deterministic replay.

dice_entropy = SHA256(dice_sequence_bytes)

deterministic: entropy_final = truncate_bits(dice_entropy, mnemonic_bits)
hybrid:        entropy_final = truncate_bits(SHA256(dice_entropy || system_entropy_32B), mnemonic_bits)
