+// rebuilt byte-for-byte the same URL, and were served the stored error within a

+//
+// The recommendation tracker id is part of that cache key, while Fever's own
+// server ignores it - page 2 comes back the same with a made-up id, or one
+// that isn't a UUID at all. So each retry asks with a fresh id, which misses
+// the stored error and reaches the origin. The first attempt keeps the id the
+// listing page gave, which is what Fever's own page sends.
