🎯 Intelligent Detection

DupeItemFixer does not simply detect large item quantities.

It analyzes:

• Transaction history
• Item source
• Item destination
• Inventory state
• Container state
• Item quantity changes
• Transaction timing
• Repeated patterns
• Legitimate item-generation sources

Detection pipeline:

EVENT ↓ TRANSACTION ANALYSIS ↓ ITEM FINGERPRINT ↓ SOURCE VALIDATION ↓ STATE COMPARISON ↓ PATTERN DETECTION ↓ CONFIDENCE SCORE ↓ CASE ↓ OPTIONAL MITIGATION
