Did the design run?

every check held
  • 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.
  • The task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer

Order O-3001 is refunded in full (68,600 cents), but two warehouse points are still open. I could not confirm the L3 restock, and the L1 and L2 restocks wait on the warehouse.

Money

  • L3 (2 × P-HUB USB-C Hub): This line had not shipped, so it was cancelled, not returned. 13,800 cents (2 × 6,900) went back to the original card as refund RF-3.

  • L1 (P-DOC Laptop Dock) and L2 (P-MON 27-inch Monitor): Both shipped on 2026-05-04 and are past the 30-day return window. Policy therefore pays them out as store credit, not card.

    • RF-1 is L1 for 21,900 cents and RF-2 is L2 for 32,900 cents. Each is the full amount paid.
    • The same 54,800 cents was added to C-300's store credit balance, taking it from 500 to 55,300.
  • No double refund: The three refunds total 68,600 cents, which matches the order total and the "refunded 68,600 of 68,600" the order showed. The unshipped-lines worker couldn't see where the 54,800 came from, but it is the shipped-lines worker's RF-1 and RF-2.

Order record

  • L1, L2 and L3 are all closed out, and the order status is "returned".
  • Shipping address untouched.
  • No other order, customer or product was touched.

Warehouse

  • L3 restock (unverified): 2 units of P-HUB went back into stock, taking it from 8 to 10, and the movement is recorded against O-3001. The line showed plain "pending" with no backorder marker, so the worker treated its stock as set aside. The inventory log has no reservation entry for this order, so that is unconfirmed. If L3 was actually backordered, the 2 units should not have been added and P-HUB should be corrected to 8. Someone should check this.
  • L1 and L2 not restocked: Returned goods go back on the shelf only when the warehouse receives them, and neither inventory record shows a receipt. Once the warehouse confirms receipt, restock 1 unit of P-DOC and 1 unit of P-MON.

Date discrepancy: The system clock read 2026-07-25 while the task date is 2026-10-06. Both are well past 30 days after 2026-05-04, so the store-credit outcome is the same either way.

Cost excludes judge calls, which are tracked separately so a scoring model never flatters or penalises an architecture. Every figure on this site is read from results/ at build time.
