Agent Memory Infrastructure: Byzantine-Resilient Institutional Memory for Multi-Agent Systems

LLM-based agent systems have made significant progress on persistent memory, yet critical gaps remain in governed multi-agent knowledge accumulation, verifiable provenance, distributed governance, and Byzantine-resilient validation of learned knowledge. We present (S)AGE (Sovereign Agent Governed Experience), a governed, verifiable, experience-weighted institutional memory layer for multi-agent systems. (S)AGE extends existing agent memory architectures with consensus-validated knowledge management backed by a novel Proof of Experience (PoE) reputation-weighted validation protocol, cryptographic audit trails, and hierarchical governance including cross-organization federation. We describe a full production…
