- Introduce BankAccount-focused concurrency tests based on Transaction → Processor → Account flow - Add stress tests for high-contention deposits, withdrawals, and bidirectional transfers - Validate atomicity and consistency across multi-threaded execution scenarios - Include deadlock detection tests under heavy transfer contention - Align all test cases with updated module structure and BankAccount concurrency contract
