fix(ai): subject 里塞了行数,每轮询一次就新建一个任务
生产上 trends 队列里积了 36 个任务,subject 是 2026-09-01:1033、:1039、 :1044……一路涨。这台账号当时正在补历史,get_summary 的行数每隔几分钟就变, 而我把 len(rows) 写进了 subject——subject 同时是缓存键和任务队列的键,一变 就是一条全新的任务,轮询几次就刷出十几条。 subject 该回答的是「这条解读是关于什么的」,不是「当时有多少行数据」。 数据变化本来就由 fingerprint 负责。 - trends 的 subject 改成快照日期;sleep 用配置的窗口常量而不是实际夜数 (缺一晚也不该换键);challenges 用固定键 - 加了不变量测试:补一天历史数据后 subject 不许变;任何 subject 段都不许 长得像行数 顺带加一层兜底 jobs.supersede():单实例 scope 只该有一个在跑的 subject, 队列里同 kind 的其它 pending 任务是关于已经不存在的快照的,跑完也没人看。 per_item 的 daily / activity 不受影响——它们本来就一天一条、一次运动一条。 兜底不是机制,机制是 subject 稳定;它存在只是因为这次 subject 不稳定,而 36 条任务堆在那里之前没人发现。 顺带按要求把 AiPanel 改成默认精简:只显示标题、来源和一句话结论,点「展开 详细」才出要点/建议/依据,可再收起——和今日晨报卡片一致。这些面板压在本来 就很密的图表页上面,全部默认展开会把真正的数据一次性挤到屏幕外。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
