Structuring Detection Logic (CBN-003)

threshold = (isCash ? ₦5,000,000 : ₦10,000,000)
structuring_line = threshold × 0.80

Trigger A: single_amount ≥ structuring_line AND < threshold
    → "Just-below-threshold" pattern

Trigger B: count(24h_txns) ≥ 3 AND sum(24h_amounts) ≥ threshold
    → Cumulative structuring
