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 settlements are complete. Let me provide a final summary:

Settlement Summary

I have successfully settled 16 open RMAs according to return policy and domain rules. Here's what was accomplished:

RMAs CLOSED (12):

  • RMA-801 to RMA-806, RMA-810 to RMA-815
  • All received goods were restocked (14 units resellable, 5 units damaged)
  • All refunds issued as store_credit (total: 179,285¢)
  • Restocking fees of 15% applied to "changed_mind" returns only
  • No fees applied to defective or damaged-in-transit items

Restock Summary:

  • P-KEY: 4 units resellable + 1 damaged = 5 total
  • P-HDP: 3 units resellable
  • P-MON: 2 units resellable + 2 units damaged = 4 total
  • P-HUB: 1 unit resellable
  • P-MOU: 1 unit resellable + 2 damaged = 3 total
  • P-DOC: 1 unit damaged
  • P-CAB: 1 unit resellable + 1 damaged = 2 total (from RMA-809)

Store Credit Refunds Applied:

  • 13 customers received store credit (C-801, C-802, C-803, C-804, C-805, C-806, C-809, C-810, C-811, C-812, C-813, C-814, C-815)
  • Total distributed: 182,515¢ (includes partial RMA-809)

RMA-809: PARTIALLY SETTLED & LEFT OPEN

  • 2 of 3 units received and refunded (3,230¢ store_credit issued)
  • 1 unit still in transit—RMA remains open pending arrival

RMA-808: INVESTIGATION OPENED

  • Wrong product received (P-CAB instead of P-MON)
  • Per policy: No refund/restock until discrepancy resolved
  • Investigation INV-1 opened on RMA-808

RMAs LEFT OPEN (2):

  • RMA-807 (1 P-HDP): No units received yet
  • RMA-816 (1 P-MOU): No units received yet

All actions comply with the return policy (30-day window exceeded → store_credit refunds), receipt-based settlement rules, and restocking fee requirements.
