Target Reference Server

0CompactMem Overview

This server stores durable agent memories in a shared SQLite database and retrieves relevant entries with BM25 and FTS5. It manages memory capacity through importance scoring, demand paging, and kswapd-style eviction, while pinning protects selected memories from reclaim. Use it when multiple agents need persistent context across sessions and compactions.
