WebSub feed link debug tool

Three RSS 2.0 feeds, identical except for how they declare, name, and place the WebSub discovery links. /feed-classic.xml is the control — conventional markup, so a reader that misses it is telling you about the reader, not the format. Hub: https://rpc.rsscloud.io/websub

Feeds

Each feed has its own hostname that advertises it and nothing else. Point a reader at the hostname to test that variant — this apex page lists all three, and a reader that takes the first rel="alternate" would only ever see the control.
