dejadb-core

Core .mg format, canonical serialization, content addressing, and grain types for DejaDB.

dejadb-core is the foundation of the DejaDB workspace. It defines the OMS grain types (Fact, Event, Observation, and the rest), the .mg binary format, and the canonical serialization used to compute each grain's SHA-256 content address. Canonical serialization is frozen — NFC normalized, sorted compact keys, defaults omitted — so an identical grain always hashes to the same address, which is what makes memories immutable and content-addressed. Every crate above it in the stack (store, CAL, context) builds on these types.
