Option 1: Run injection incident reconstruction without defining transaction boundaries, r

Run injection incident reconstruction without defining transaction boundaries, retry behavior, or production validation.

Additional Explanation

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