当专家纠正大语言模型（LLM）助手的错误时，该纠正通常仅在当前会话中生效，错误类别会再次出现。本文认为这是一个运营问题而非工具问题：持久化纠正的机制已存在并正在部署，但管理这些机制的规范——带来源的版本控制、复发监测、反指标、过时规则的弃用——尚未建立。作为拥有三十年经验的系统工程师，我将LLM栈映射到本行业已在运营的机器（冻结硅、固件、可加载模块、持久化配置、易失性内存），识别映射失效之处（随机生成、仅概率性绑定的配置、默认无通用弃用（验证）阶段），并从这些失效中推导出以错误循环为核心的七项运营规范。我实践中的三个案例阐释了该机制，其中一个控制措施悄然变成了它本应防止的危害。最后，我提出了该视角隐含的测量框架及验证所需的实验室研究。
英文摘要
When an expert corrects an LLM assistant's error, the correction usually dies with the session, and the error class returns. I argue this is an operations problem, not a tooling problem: mechanisms for persisting corrections exist and are shipping, but the discipline for governing them -- versioning with provenance, recurrence monitoring, counter-metrics, retirement of stale rules -- does not. Writing as a systems engineer of thirty years, I map the LLM stack onto the machines my profession already operates (frozen silicon, firmware, loadable modules, persistent configuration, volatile memory), identify where the mapping fails (stochastic generation, configuration that binds only probabilistically, no general-purpose retirement (verification) stage by default), and derive from the failures a seven-principle operating discipline with an error loop at its core. Three cases from my own practice illustrate the mechanism, among them a control that silently became the exact harm it was built to prevent. I close with the measurement framework this view implies and the lab study required to test it.
