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 steps completed successfully. Here's the final summary:

Order O-3001 Return - Complete Processing for Priya Raman (C-300)

What was done:

  1. ✅ Cancelled L3 (P-HUB, 2 units) - Refunded 13,800¢ to card (original payment method) because this line never shipped. This is a cancellation, not a return.
  2. ✅ Refunded L1 & L2 to store credit - Both shipped on 2026-05-04, now 82+ days in the past (well outside the 30-day return window). Per policy, returns outside the window must be paid as store credit, not to card. Total: 54,800¢.
  3. ✅ Restocked inventory - 2 units of P-HUB returned to warehouse stock (cancelled goods re-enter immediately). Stock: 8 → 10 units.
  4. ✅ Applied store credit - Added 54,800¢ to Priya's account. Her balance: 500¢ → 55,300¢.

Final State:

  • Order O-3001: Status returned, 100% refunded (68,600¢)

    • L3: Cancelled, refunded 13,800¢ to card
    • L1 & L2: Returned, refunded 54,800¢ as store credit
  • Customer C-300: Tier platinum, store credit 55,300¢
  • Warehouse: P-HUB stock restored to 10 units

All actions follow the domain policy: L1 & L2 respect the 30-day window boundary; L3 follows cancellation rules; refunds match what was paid; store credit refund is complete (both order record and customer balance updated).
