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

Perfect! All refunds are complete. Let me verify the final state:

Summary of Actions Completed:

✅ L3 (P-HUB, Pending — Cancellation)

  • Cancelled line
  • Refunded $138.00 to original payment method (card)
  • Restocked 2 units of P-HUB immediately (goods never left warehouse)

✅ L1 & L2 (Shipped — Out-of-Window Returns)

  • L1 (P-DOC): $219.00 refunded to store credit
  • L2 (P-MON): $329.00 refunded to store credit
  • Combined refund of $548.00 applied to customer's store credit account
  • Not restocked (goods awaiting physical return to warehouse per policy)

✅ Order O-3001 Status

  • Total paid: $686.00 → Total refunded: $686.00 (100% complete)
  • Order status: changed to "returned"

✅ Customer C-300 (Priya Raman)

  • Store credit updated: $5.00 → $553.00
  • Received full refund value: $138.00 (card) + $548.00 (store credit)

Why this satisfies policy:

  • Pending items (L3) treated as cancellations, refunded to card regardless of order age
  • Shipped items >30 days old (L1, L2) refunded to store credit only (per return policy)
  • Cancelled inventory restocked immediately; returned inventory held for warehouse receipt
  • Full order value ($686) refunded as requested

The task is complete and fully policy-compliant.
