A 14-slide technical review of a silent data incident
A technical Working Deck for a silent freshness failure. It follows false success telemetry through backfill, reconciliation and the controls that make “job completed” mean “customer data is correct.”

What to notice
- The review starts with the false success signal rather than the retry code.
- It gives backfill its own validation and rollback path.
- The corrective work is expressed as customer-visible freshness and acknowledgement contracts.
What it does not do
- The data volume, timing and customer impact are illustrative.
- It does not inspect a real queue, warehouse or orchestration system.
- A production replay still requires environment-specific safeguards.
