Roadmap

v5.0 -- Performance & Scale

Scalability improvements for 5K+ memories.

• sqlite-vec ANN vector indexing
• FTS5 keyword search
• remember_batch() for bulk inserts
• Category as real column with composite covering index and CHECK constraints
• Persist decay to DB, separate last_accessed_at from updated_at
• backup()/restore() API
• StoreProtocol abstract interface
• NumPy-accelerated cosine similarity

v5.x -- Adaptive Memory

Spaced-repetition learning, automatic memory consolidation, cross-session linking, multi-device sync.
