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! I've successfully processed Priya Raman's full order return. Here's what was completed:

Summary of Actions

Order O-3001 - Full Return Processed

  1. L3 (P-HUB x2, pending/unshipped) - Cancellation

    • Cancelled the line
    • Refunded 13,800¢ to original payment method (card)
    • Restocked 2 units of P-HUB immediately (8 → 10 units)

  2. L1 & L2 (P-DOC + P-MON, shipped 82 days ago) - Return Outside Window

    • Both lines marked as returned (refund RF-2)
    • Refunded 54,800¢ (21,900¢ + 32,900¢) as store credit (per policy: >30 days post-shipment)
    • No restock issued yet (goods haven't been received back at warehouse)

  3. Customer Account Updated

    • Store credit balance increased from 500¢ to 55,300¢ (added 54,800¢)

Final Order Status: Returned | Total refunded: 68,600¢ (100% of order)

The process followed the domain policy precisely: unshipped items refunded to card with immediate restocking, shipped items outside the return window refunded as store credit with deferred restocking pending warehouse receipt.

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.
