Ziel

Verifizierte Collection erhält reproduzierbare Punkte mit Breakdown; FraudScore + Trust sichtbar; Storno funktioniert.

Items (Backlog P4-01 … P4-07)

  • P4-01 Score-Policy-Modell (versioniert, Default v1 Seed)
  • P4-02 Score-Engine (deterministisch, Faktor-Breakdown, Obergrenze)
  • P4-03 Point-Transaktionen (Append-Only Ledger, Storno = Gegenbuchung, Idempotenz)
  • P4-04 Scoring-Pipeline (Worker: analysis.completed → points.awarded)
  • P4-05 Anti-Fraud Schicht 1 (Photo: pHash-Duplikat, EXIF-Zeit, Qualität)
  • P4-06 Anti-Fraud Schicht 2 (Heuristik: Geschwindigkeit, Mengen, Standort)
  • P4-07 Verification & Trust Score (EMA, Verifizierungsfaktor in Score v1)

Abhängigkeiten

← P1-02, P3-02/03, P2-04

Acceptance

Reproduzierbarer Score mit auditierbarem Breakdown; FraudAssessment + TrustScore pro Collection; Storno lässt Saldo korrekt.
