Did the design run?
- Run completed: heldharness.run-completedThe environment was built, the architecture returned and grading finished, none of them throwing.
- No API failures: heldharness.apiNo model call failed at the API.
- Every call ended: heldharness.calls-endedEvery call ended with a result, or was stopped by the run's own limits.
- No harness tool denied: heldharness.harness-toolsThe sandbox guard never denied a harness tool, nor a tool the session itself offered.
- Tool servers connected: heldharness.mcp-connectedEvery tool server the harness gave a call was connected when the session started.
- No foreign tool servers: heldharness.mcp-hermeticNo call loaded a tool server the harness did not give it.
- Builtin tools: heldharness.builtin-toolsA check recorded with the run.
- Structured replies arrived: heldharness.structured-outputEvery call that asked for structured output and ran to the end got it.
- No silent fallbacks: heldharness.not-degradedNo phase fell back on a default (an empty plan, a default winner) instead of its output.
- Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.

Final answer
Order O-3001 is fully refunded: 54,800 cents as store credit and 13,800 cents back to the card.
- L3 (2 × USB-C Hub, never shipped): I cancelled it and refunded the 13,800 cents to the original card. I put the 2 units back into stock (P-HUB went from 8 to 10). The line showed as pending, not backordered, so I treated the stock as set aside for it. If it was actually backordered, that restock should be reversed.
- L1 (P-DOC) and L2 (P-MON), both shipped 2026-05-04: The return window is 30 days from the ship date, and it closed long ago. Policy says these must be paid as store credit, not to the card. I recorded the refund against the order (RF-1, 54,800 cents) and added the same amount to Priya's balance. Her balance went from 500 to 55,300 cents.
- Warehouse: I did not restock P-DOC or P-MON. Returned goods only go back on the shelf once the warehouse receives them, so that restock is still to do when they arrive.
The order now shows as returned, with 68,600 of 68,600 cents refunded.
Priya asked for her money back, and the shipped items can't go back to her card under the policy. She should be told that part comes as store credit.
