FactDb implements the Event Clock concept - capturing organizational reasoning through temporal facts with validity periods (valid_at/invalid_at), entity resolution, and audit trails back to source content. Built on PostgreSQL with pgvector support for semantic search.

HTM (Hierarchical Temporal Memory) provides intelligent memory/context management for LLM-based applications. It implements a two-tier memory system with durable long-term storage (PostgreSQL) and token-limited working memory, enabling applications to recall context from past conversations using RAG (Retrieval-Augmented Generation) techniques.
