Deterministic consolidation, a typed graph in SQLite, and an honest look at what agent-memory benchmarks can and can't measure. You're building an agent. It answers questions across many sessions, and by session three it has forgotten what it learned in session one. The reflex is to put a vector database in front of it - and now it remembers a blurry average of everything, ranked by cosine distance, contradicting itself and unable to tell a three-week-old preference from a stale throwaway.
