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
Perfect! I've completed the full return processing for Priya Raman's order O-3001. Here's what was done:
Summary of Actions:
Order Processing:
- Cancelled L3 (P-HUB, qty 2, pending line) as a cancellation
- Refunded L3 to original card: 13,800 cents (line never shipped)
- Refunded L1 & L2 as store credit: 54,800 cents (return window closed—shipped 2026-05-04, requested 2026-07-25 = 82 days, exceeds 30-day window)
Warehouse:
- Restocked 2 units of P-HUB to inventory (cancelled line goods never left warehouse)
Customer Account:
- Added 54,800 cents store credit to Priya's balance (500 → 55,300 cents)
Total Refunded: 68,600 cents (full order amount)
- Card: 13,800 cents
- Store credit: 54,800 cents
Order Status: Now marked as "returned" with all lines fully refunded.
The entire order has been processed end-to-end per policy: the shipped items (L1, L2) were refunded via store credit due to the closed return window, the unshipped item (L3) was cancelled and refunded to card, and inventory was restored to the warehouse.
