UnverifiedAfter locating the erroneous step, StepBack resamples only that step and its subsequent suffix rather than generating the entire trajectory from scratch, thereby preserving the correct reasoning in the prefix.70% similarUnverifiedThe core challenge in fallback chain design is determining which errors warrant triggering a fallback and which errors should be surfaced directly as exceptions.61% similarUnverifiedPartially recoverable errors (such as a tool call failure where an alternative exists) should trigger a fallback path.61% similarUnverifiedThe decision layer backend adopts a Bayesian Beta posterior, updating based on historical results in memory, and confidence moves as evidence accumulates.60% similarUnverifiedIf the man-in-the-middle routing layer does not strictly validate responses, it may also be subject to injected malicious content (such as returned code snippets with backdoors).60% similar
