For frontier models, checkpoint leakage could lead to the model being copied or misused, while tampering could contaminate subsequent training.

在搜索与训练耦合的循环中,仅保存最新权重无法完整恢复实验状态,因为模型检查点与搜索档案共同描述同一个演化中的实验,恢复时必须成对还原。

原帖作者提出一个恢复检查思路:在一次运行中于某个 step 边界处中断;检查恢复时究竟是哪个档案与哪个模型版本一起被加载;如果出现错配,恢复流程应当暴露出来,而不是静默继续。

原帖认为有意思的基础设施贡献是让 checkpoint 与 archive 的配对显式化(making the pair explicit),把绑定关系写进提交逻辑并在不匹配时 fail closed。
