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

Task Completion Summary

Status: ✓ Complete

The worker successfully completed the task in full accordance with the requirements:

  1. Wireless Mouse Cancelled: Line L1 (P-MOU, 2 units) was cancelled with status "cancelled"
  2. Refund Issued: RF-1 refund of 7,350 cents issued to Marcus Ade's original payment method (card) for exactly what he paid for the wireless mice
  3. Inventory Restored: 2 units of wireless mouse returned to stock (30 → 32 units)

  4. Order Integrity Maintained: Order O-2003 remains in "pending" status with the other two lines still active:

    • Line L2 (Hub - P-HUB): 1 unit, pending → will ship
    • Line L3 (Cable - P-CAB): 3 units, pending → will ship

The action was properly scoped to only the wireless mouse item. The refund method matched the original payment method (card), the refund amount matched what was actually paid, inventory was correctly restocked from cancelled stock, and the remaining order lines remain unaffected and scheduled to ship as planned.

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.
