Option 1: Use a parameterized, transaction-aware MySQL 8 implementation for generated-data

Use a parameterized, transaction-aware MySQL 8 implementation for generated-data incident, validate the invariant, and explicitly test concurrency, retries and recovery.

Additional Explanation

Correctness depends on explicit invariants, safe SQL, transaction/concurrency handling and verification.
