Der stündliche Abruf der 502 Feeds dauerte 114 s, fast nur Parsen: viele Server ignorieren ETag/Last-Modified und schicken jedes Mal den ganzen Feed (Lage der Nation 8,4 MB = 5,9 s). ⟳ in der App lief damit in ihr 60-s-Zeitlimit und schlug fehl. - Fingerabdruck des Feed-Inhalts (ohne lastBuildDate/Kommentare, http_body_hash, Migration 0017): derselbe Inhalt zählt als unverändert und wird nicht geparst - _refresh_feeds: ein Pool für alle Feeds (16 parallel), jeder Feed wird geschrieben, sobald er da ist, optionales Zeitlimit - refresh-all wartet höchstens 40 s (done/left in der Antwort); der Browser-Host holt den Stand dann eine Minute später noch einmal, und alle 15 Minuten Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
