memory-substrate

Memory substrate and agent runtime for AI systems that have to be trusted — grounded facts and simulated hypotheses never mix, and every retrieval call reports index drift instead of hiding it.

The primitive layer of LLM-native knowledge systems — a memory substrate where documents are the smallest unit of intelligence infrastructure.

Evidence-Bound Retrieval (EBR) — accretive memory for AI agents. Amendment records, structural precedence, BM25. A substrate for CoALA's episodic memory layer.

Memory as advisory for LLM agents — forgets noise, keeps what matters. Lazy exponential decay, four-op API, OpenUSD cold tier. Python ≥3.11. Patent-pending.
