"""Core protocol layer: canonical encoding, identifiers, keys, signed
operations, and the append-only operation log.

These modules implement the wire format and operation-log schema
published in milestone 2 ("MNC-1" canonical encoding, ed25519-signed
operation envelopes, content-addressed operation ids). The derivation
engine in :mod:`mnema.derive` is built strictly on top of this layer so
that another implementation can interoperate by speaking the same wire
format.
