UnverifiedRouting without an escalation path is not routing but downgrading; each tier needs explicit failure conditions (such as schema validation failure, low confidence, refusal, timeout) to promote requests to a higher tier.67% similarUnverifiedCommon gateway strategies during upstream degradation include fast failure, silent retries to a higher-priced tier, and returning a model that was not requested.65% similarUnverifiedThe critic node in LangGraph can send the route back for a retry, relaxing constraints if the target length cannot be reached.61% similarUnverified路由层不压缩的工程依据是：路由错误会在整个前向传播中级联放大且无法后续纠正，而路由层参数量占比极低61% similarUnverified单体路径的优势是迭代速度快、目标统一，风险是失控与不透明61% similar
