It injects production-style API failures into data-writing agents, then checks the exact resulting records rather than asking a model to judge the run.

- Worth noticing
- The page cites a run with four duplicate writes among 146 movements; its grader also rejects invented balancing entries that pass a totals check.
Field notes
The described test setup uses private scenario seeds and a controlled API that injects faults on a fixed, reproducible schedule. Its grader checks every record against a recomputed end state, including whether writes were duplicated or invented. The page says teams can test mocks of their own tools without granting production access or sharing data.
