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 plan was a plan: heldplan-execute.planThe planner’s reply was read through its schema and held at least one step.
  • Each call was shown the right tools: heldplan-execute.toolsThe planner was shown no tools and the executor 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

Perfect! The task has been completed successfully. Here's what I did:

Summary

Order O-2003 for Marcus Ade (C-200):

  1. ✅ Identified the wireless mouse line: Line L1 (product P-MOU, qty 2) charged at 7350 cents
  2. ✅ Verified shipment status: Line was in "pending" status (not shipped), so cancellation was allowed
  3. ✅ Cancelled the wireless mouse only: Line L1 cancelled while lines L2 (hub) and L3 (cables) remain active and pending
  4. ✅ Processed refund to card: Refund of 7350 cents recorded to the original payment method (card) via refund RF-1
  5. ✅ Restored inventory: 2 units of wireless mouse (P-MOU) returned to stock (stock increased from 30 to 32 units)

Final Order State:

  • L1 (Wireless Mouse): Cancelled - Refunded 7350 cents to card ✓
  • L2 (Hub): Pending - Will ship as planned
  • L3 (Cables): Pending - Will ship as planned
  • Order status: Pending (ready to ship the remaining items)

The rest of the order remains unchanged and will ship according to the original plan.

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.
