Investigation

Diagnosis supported

Supported under the tested sandbox assumptions: The agent derives the refund amount from the request incorrectly, and the defect depends on the size of the amount: above some magnitude the amount it sends to the payments provider differs from the amount requested. Observed mapping in the sandbox: 2000 → 2000, 6000 → 6000, 8000 → 8000, 9000 → 9000, 9500 → 9500, 10000 → 1000 (requested → issued, minor units). In every failing run the issued amount was 10% of the requested amount. Requests of 9500 pass and requests of 10000 fail, so the defect switches on between them. In 2 of 2 failing agent run(s), its completion message disagreed with the observed outcome. Historical attribution remains unverified.
