  • 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.

  • 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.

Final answer

The wireless mouse has been cancelled from order O-2003 and refunded to Marcus Ade's card. The rest of the order is still set to ship as planned. This comes from one worker's report; I couldn't check the system myself.

What was done:

  1. Cancelled line L1 (wireless mouse, P-MOU, quantity 2). It hadn't shipped, so this was a cancellation, not a return.
  2. Refunded 7,350 cents (£73.50) to his card (refund RF-1). That's what Marcus actually paid for the mice. The list price was 9,800 cents (2 × 4,900), but discount code MOUSE25 took 25% off. The refund can't be more than he paid, so 7,350 is correct. The numbers add up: 7,350 + 6,900 (hub) + 5,700 (cables) = 19,950, the order total he paid.
  3. Put both mice back into stock. The line had stock set aside and wasn't backordered, so P-MOU went from 30 to 32.

Current state of O-2003: status is still pending. Lines L2 (hub) and L3 (cables ×3) weren't touched and will ship as planned. The shipping address is unchanged. Nothing else was cancelled, refunded or restocked.

Minor note: The worker found two different "today" dates: 2026-10-05 from the system and 2026-07-25 on the order record. This didn't affect anything, because cancelling an unshipped line doesn't depend on the return window.

You may want to tell Marcus the refund is £73.50 rather than £98.00 and explain that it reflects his discount.

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.
