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-verify.planThe planner’s reply was read through its schema and held at least one step.
  • Every verdict was read: heldplan-execute-verify.verdictsEvery review round ended with a verdict read from the schema reply, not a default.
  • The loop did what its verdicts said: heldplan-execute-verify.loopEvery verdict that called for a revision got one, and nothing was revised without such a verdict.
  • Each call was shown the right tools: heldplan-execute-verify.toolsThe planner was shown no tools, the verifier the read-only ones, and the executor and reviser 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

Perfect! I have successfully processed Priya Raman's full return end-to-end. Here's what was completed:

Summary of Actions

Order O-3001 - Full Return Processed

Refunds Issued:

  1. L3 (P-HUB × 2) - Refund RF-1: 13,800 cents → Card (unshipped cancellation)
  2. L1 (P-DOC) & L2 (P-MON) - Refund RF-2: 54,800 cents → Store Credit (shipped 82 days ago, outside 30-day return window per policy)

Total Refunded: 68,600 cents (100% of order)

Inventory Restoration:

  • Restocked 2 units of P-HUB (from cancelled line L3) — inventory moved from 8 → 10 units

Customer Account:

  • Applied 54,800 cents store credit to customer C-300 (Priya Raman)
  • Store credit balance: 500 → 55,300 cents

Order Record:

  • L1 & L2: Status changed to "returned" (policy: outside return window, store credit)
  • L3: Status changed to "cancelled" (policy: unshipped, card refund)
  • Order O-3001: Status now "returned" — fully refunded

Policy Compliance: The refund methods followed the return policy exactly — unshipped items get refunded to the original card payment method, while shipped items outside the 30-day window are refunded as store credit per policy.
