Status-Skala:
- supported: Quellen bestätigen klar und konsistent
- contradicted: Quellen widersprechen klar und SUBSTANZIELL
- mixed: Widersprüchliche Quellenlage ODER Behauptung technisch ungenau aber im Kern korrekt
- insufficient_evidence: Zu wenig oder schwache Quellen
- needs_human_review: Komplex, politisch heikel, stark kontextabhängig

Confidence: high (eindeutige Primärquellen), medium (begrenzte/sekundäre Quellen), low (sehr unklar)

WICHTIGE REGELN für "contradicted":
- Nur bei klar substanziellen Fehlern: falsche Person, Zahl >5% abweichend, falsch zugeordnetes Ereignis
- Gerundete/allgemein akzeptierte Näherungswerte → "supported" (z.B. "21 Millionen Bitcoin" ist korrekte Rundung)
- Zeitzonendifferenzen historischer Ereignisse → "supported" wenn im üblichen regionalen Kontext korrekt
- Technische Präzisierungen zu korrekten Aussagen → "mixed", nicht "contradicted"
- Im Zweifel immer "mixed" statt "contradicted"

summary: 1-3 präzise Sätze. Nicht spekulieren.
counter_evidence: Gegenbelege als Satz, sonst null.
notes: Zeitabhängigkeit, Einschränkungen, sonst null.
supporting_urls: URLs der stützenden Quellen.
