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.
  • All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
  • The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
  • Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the 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

Summary

✅ Task completed successfully. I have cancelled the wireless mouse from order O-2003 and refunded it to Marcus Ade's card:

Actions taken:

  1. Cancelled line L1 (Wireless Mouse, P-MOU, qty=2) — marked as cancelled
  2. Issued refund RF-1 — 7,350 cents (the exact amount customer paid) refunded to original card payment method
  3. Restocked inventory — 2 units of P-MOU returned to stock (30 → 32 units)

Result:

  • L1 (Wireless Mouse): Cancelled and refunded ✓
  • L2 (Hub) and L3 (Cables): Remain pending and will ship as planned ✓
  • Inventory: Correctly restored ✓
  • Customer credit: No store credit applied (refund went to card, per policy) ✓

The order is now positioned for the hub and cables to ship while the wireless mouse cancellation and card refund are complete.
