dev.bastienrobert.memory.record

A single durable memory belonging to the user. Deliberately one generic type: specialising into fact/preference/project/event types is premature until real requirements demand it. Retrieval-specific state (BM25 scores, vector ids, index cursors, caches) MUST NOT be stored here — it is derived data owned by whichever memory engine indexes this record. Consumers MUST preserve properties they do not recognise: an implementation that rewrites a record after dropping unknown fields destroys data written by a newer one.
