ctrlz is a production-reliability platform for AI agents that brings state rollback, causal lineage tracing, and dynamic guardrail evolution to persistent memory stores.   
Preventative write-filters cannot catch 100% of memory poisoning attacks. When an attack slips through and triggers harmful downstream side-effects, ctrlz traces the causal dependency tree back to the origin write in MongoDB Atlas. It selectively rolls back tainted actions—like refunding an unauthorized transaction via Stripe—while preserving parallel valid state, such as an active hotel reservation. 
 Once an incident is resolved, ctrlz automatically evaluates guardrail policy variants, tests them against benchmark suites like MPBench (achieving a 1.47% false positive rate across 6,238 test cases), and deploys updated rules to prevent future exploits. ctrlz transforms fragile agent demos into resilient, production-ready systems.
