GASLIT
Belief-layer security system that intercepts memory poisoning attacks against AI agents using four coordinated agents, HMAC verification, and adaptive retrieval contracts.

Challenge
Memory poisoning attacks bypass traditional kernel sandboxes and LLM guardrails because individual queries appear benign — the malicious pattern only emerges across an agent's long-term memory.
Approach
Built a belief-layer interceptor sitting between MongoDB and the LLM context, with four specialized agents coordinating through change streams to detect injection attempts via cohort statistical analysis, HMAC verification, and adaptive retrieval contracts.
