open-source memory infrastructure for AI agents. Production AI agents are amnesiac by default: no persistent memory across sessions, no governance layer, no recovery after failure, no audit trail. Metronix solves this at the infrastructure level: persistent memory stores, structured state and event history, recovery checkpoints, RBAC permission boundaries on memory reads/writes/handoffs, agent-to-agent context sharing with provenance, and immutable audit trails. Open source (Apache 2.0), self-hosted, MCP-compatible. Benchmark: 89.7% Recall@10 on LoCoMo vs 16.3% for the nearest commercial alternative — a 5.5x retrieval advantage**. 1–3 active pilots. Raising seed.
