这是一份内部工作手册的对外版（2026-08-28，v2）。它把前两篇——为什么这样设计、怎么运转——放回整个工作流的全貌里：底座、投放线、数据线、方法、待办。中文。The public version of an internal working manual (v2, 2026-08-28). It places the two earlier notes — why it's built this way and how the loop runs — back into the full picture: foundations, the paid-media line, the data line, method, open items. Chinese only.
