POSSIBLE BUG TYPES (choose exactly one):
- CALC_ERROR: Mathematical calculation is incorrect
- NEGATIVE_BAL: Account balance becomes negative
- LOST_UPDATE: Concurrent update causes lost transaction
- DUPLICATE_TXN: Same transaction processed multiple times
- MONEY_LEAK: Total money in system changes
- NONE: No bugs found - all transactions are correct
