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

The wireless mouse on order O-2003 is cancelled, Marcus has been refunded $73.50 to his card, and the rest of his order is still due to ship as planned.

  • What was cancelled: line L1, the 2 wireless mice, and nothing else. The line hadn't shipped, so this is a cancellation rather than a return.
  • Refund: $73.50 went back to his card (refund RF-1). That's what he actually paid for the mice after his MOUSE25 discount, not the $98.00 list price.
  • Stock: the mice weren't backordered, so both units had been set aside for him. They've been put back in stock, taking wireless mouse stock from 30 to 32.
  • Rest of the order: the hub (L2) and the 3 cables (L3) haven't been touched. They're still pending, going to the same shipping address. The order now shows $73.50 refunded out of $199.50 paid.

Two things to be aware of:

  1. Discount code: MOUSE25 looks like it was tied to the mouse. The refund system counted the discount against the mouse line only, and the hub and cable prices didn't change. So nothing else on the order needed adjusting.
  2. Date mismatch: the order record gives today's date as 2026-07-25, but the actual date is 2026-10-06. This didn't affect the cancellation because the items hadn't shipped, but the system clock may be worth checking.
