## Key Findings

### ✅ What's Working Correctly

1. **Calculation Logic**: All financial calculations (interest, fees, outstanding amounts) are accurate
2. **Repayment Scheduler Integration**: The system correctly uses `RepaymentScheduler` for:
   - Determining next payment due dates
   - Calculating expected payment amounts
   - Identifying loans in arrears
   - Categorizing by repayment method (daily/weekly/monthly)

3. **Delinquency Thresholds**: Smart thresholds based on repayment method:
   - Daily loans: Mild (≤3 days), Moderate (≤7 days), Severe (>7 days)
   - Weekly loans: Mild (≤14 days), Moderate (≤21 days), Severe (>21 days)
   - Monthly loans: Mild (≤30 days), Moderate (≤60 days), Severe (>60 days)

4. **Branch Filtering**: All reports respect branch filtering when `branch_id` is provided
5. **Portfolio Filtering**: Reports support portfolio manager filtering
6. **Soft Delete**: Correctly excludes soft-deleted loans (`is_deleted=False`)
