# Implementer — POS-PAYMENT-OVERPAY-FIX

## Changes
- Frontend (terminal page): clamp `amountCents` to `Math.min(remainingCents, totals.total)` to avoid 1-cent overpayment
- Backend (create-pos-sale): allow 1-cent tolerance in payment overpayment validation to absorb rounding diffs between frontend cached prices and backend canonical total

## Validation
- `cd project && npm run build` ✅
- `cd project/apps/pos && npm run build` ✅
