Duplicate Event Processing

Consumer acknowledgements to the broker are failing intermittently, and unacknowledged messages are being redelivered. Order and payment processing must remain idempotent — an order or payment side effect applying more than once for the same underlying event is a critical integrity incident, not a cosmetic one, regardless of how healthy throughput and acknowledgement metrics otherwise look. Diagnose why redelivery is occurring and bring the system to a state that is genuinely safe to hand back, not merely fast.
