MemoryTier

Letta-style memory tier. Alias for MemoryType; the same four variants describe both “what kind of memory is this” (Episodic/Semantic) and “how should the engine treat it” (Working TTL, Procedural importance floor, Episodic per-session logging). Kept as a single type to avoid carrying two semantically-redundant fields on every record.
