UnverifiedMemory drift is an easily overlooked failure mode in long-running agents, where early misjudgments can become premises for subsequent inferences, forming erroneous self-reinforcing loops.79% similarUnverifiedWhen multiple agents share the same long-term context, erroneous memories and information that should not be shared are amplified together, forming a positive feedback loop of memory contamination.74% similarUnverifiedMemory retrieval should layer in time decay, importance weighting, and hybrid retrieval, rather than relying solely on vector similarity.74% similarVerifiedInterleaved practice yields significantly higher long-term memory retention rates and knowledge transfer ability than blocked learning.74% similar
