Rueckmeldung nach Vertrauensstufe: drei Wege nach oben (#715)
- IAgentTool.ReadsForeignContent: Werkzeuge mit Aussenkontakt erklaeren sich selbst (WebFetch, WebMonitor, DirectAPI, Mail, RocketChat, Telegram, TelegramClient, SocialMediaManager, FTP, Database); AgentConfig.TreatAsForeignReader kann nur verschaerfen - ReportingLine: Stufe aus den Werkzeugen, "wer steht darueber", Pruefung des Wegs nach oben (nie Aenderungen an Aufgaben darueber, nur eine Ebene hoch, Fremdinhalt-Stufe gar kein Freitext) und Rahmung als untrusted_content - Engine: Nachricht und Spawn nach oben geprueft, Text der Fremdinhalt-Stufe kommt gerahmt an - Taskboard: task_create/update/comment, reopen und die Dubletten-Notiz folgen dem Berichtsweg - Dispatcher: Aufgaben von Agenten der Fremdinhalt-Stufe gehen gerahmt in den Lauf - TaskReports: Erledigt-Signal und Systemmeldung (in Pruefung, blockiert, abgebrochen) an den Auftraggeber, je Zustand einmal, gesammelt in einer offenen Aufgabe je Empfaenger - OrgBriefing nennt den Berichtsweg; WebUI zeigt Stufe und Schalter am Agenten Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
