Fehler melden mit Screenshot und Markierung, Sammlung für Bearbeiter
Käfer-Button unten rechts: nimmt den sichtbaren Bildschirm mit html2canvas (selbst gehostet) auf, Vorschau mit roten Rechtecken, Beschreibung, Name optional, Senden ohne Anmeldung. Aus offenen Dialogen heraus wird der Dialog selbst aufgenommen. Bearbeiter sehen die Meldungen unter „Fehler" mit Zähler, kopieren einen fertigen Claude-Prompt und den Screenshot. Serverseitig: Pfade nur in exakter Schreibweise, /api standardmäßig nur für Bearbeiter mit ausdrücklicher Freigabeliste, Bremse zählt jeden Versuch vor dem Lesen großer Bodies, X-Forwarded-For nur von vertrauten Proxys, Nutzertext im Prompt eingezäunt. HTTP-Tests für die Sperren. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
