This week in AI - 1 story

This week, we're looking at one of the quieter dangers lurking inside agentic AI systems: not the hallucination you catch at the end, but the ones that slip through early and quietly corrupt everything that follows. CHARM offers a formal way to think about this "cascading hallucination" problem in multi-step RAG pipelines - and more importantly, a practical architecture for stopping errors before they snowball. By the end, you'll have a clearer mental model of why chaining retrieval and reasoning steps together creates compounding risk, and what it actually takes to build a system that can catch itself going wrong.
