    // ERROR: value moved in line 63
    let model = SecondaryBettingModel::new(config)?;  // config moved here
    ...
    assert!(decision.confidence >= config.min_confidence);  // used after move
    
    // FIX: Clone config before move
    let model = SecondaryBettingModel::new(config.clone())?;
    

Impact: Test-only ownership issue (implementation is correct) Fix Time: 2 minutes (add .clone()) Production Status: Implementation code is READY (only test blocked)
