- Umfassende Analyse der aktuellen Implementierung durchgeführt - Identifiziert: Zwei getrennte User-Systeme (users vs gateway_users) - Problem: API verwendet falsche Tabelle (users statt gateway_users) - Lösung: Kompletter Implementierungsplan für korrekte Architektur - Dokument: ARCHITEKTUR.md mit 6-Tage-Umsetzungsplan erstellt - Enthält: Custom API-Key Guard, Gateway-User-Credentials, Budget-System - Swagger/Scramble Paket hinzugefügt (für spätere API-Dokumentation) Status: Bereit für Implementierung (Start: Tag 1 - Datenbank & Models)
