Cascading Hallucination in Agentic RAG: The CHARM Framework for Detection and Mitigation

In three linesCHARM detects and mitigates cascading hallucinations in multi-step RAG pipelines, where early errors propagate and amplify across reasoning stages. Four-component framework: stage-level fact verification, cross-stage consistency tracking, confidence propagation monitoring, cascade resolution. 89.4% detection rate on HotpotQA/MuSiQue/2WikiMultiHopQA, 82.1% error propagation reduction.
