Module code 

One-time code policy, generation, normalization, and validation (RFC-003).

The four representations of a code are kept distinct (RFC-003 §11.2): generated plaintext and user input are crate::secret::PlainCode / normalized String (secret, never persisted); the persisted value is a crate::hashing::LookupKey derived in the crate::hashing module.
