接口兼容不等于迁移成本为零。A compatible interface does not mean a zero-cost migration.
换模型只是把配置里的名字改一下。Switching models is just changing a name in the config.
配置可能只改一行，但提示、工具参数、输出解析、质量、成本与数据条款都可能受影响。先用代表性输入比较并保留回滚方式，再决定是否完成迁移。Configuration may change by one line while prompts, tools, parsers, quality, cost and data terms change materially. Compare representative inputs and retain rollback before declaring migration complete.

即使只改了配置中的 model 字段，也要检查旧提示词、输出解析、工具参数与错误处理。保留一个会失败的样本，确认新模型不会绕过接收端校验。Even when only the model field changes, check prompts, output parsers, tool arguments and errors. Keep a failing example to ensure the new model cannot bypass receiving-end validation.
