Unverified离线RL的核心难题是如何避免对数据集未覆盖的状态-动作对产生过于乐观的价值估计（分布外外推问题）75% similarUnverifiedClaude Code discovered deep-level resource leak risks such as ClassLoader isolation potentially preventing GC and unbounded growth of index metric data with no automatic cleanup.62% similarUnverifiedRow-Level Security (RLS) pushes permission checks down to the database layer, so that even if there are vulnerabilities in the application layer code, the database layer will not return unauthorized data.61% similarUnverified作者建议在lx中避免使用推理/思维链模型（如QwQ、DeepSeek-R1），因其思维链会消耗大量token预算导致结果被截断60% similarUnverified在高并发下，底层大模型推理服务（如vLLM、TGI、Ollama）可能因GPU显存不足或请求队列溢出而截断响应或拒绝请求59% similar
