- Use Prisma $transaction with Serializable isolation level - Insert idempotency record FIRST, then execute business logic - Unique constraint violation (P2002) indicates duplicate event - All operations atomic - either fully commit or fully rollback - Modified all handlers to accept transaction client parameter - Removed old non-atomic isEventProcessed/recordProcessedEvent methods This ensures 100% data consistency for CDC synchronization, which is critical for financial data where any error is catastrophic.
