## Metrics Summary
- **nSLOC:** $NSLOC
- **Complexity Score:** $COMPLEX

## Audit Duration
The estimated duration of the audit is approximately **$AUDIT_DURATION days**.

## Audit Cost
The estimated cost of the audit is **\$${AUDIT_COST} USD**.

## Payment Schedule
Payments for this audit are structured as follows:
- **Upfront Payment (25%):** \$${UPFRONT_PAYMENT} USD
- **Initial Report Payment (50%):** \$${INITIAL_REPORT_PAYMENT} USD
- **Final Report Payment (25%):** \$${FINAL_REPORT_PAYMENT} USD

### Notes:
- The duration and cost are calculated based on the size and complexity of the codebase.
- If additional constraints or requirements exist, adjustments may be necessary.
