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

Summary

I have completed the work that could be done under the domain policy constraints:

✅ RMA-809: SETTLED (2 of 3 units)

  • Refunded: 3,230 cents via card to customer C-809 for 2 units received

    • Per unit: 1,900 cents paid - 285 cents (15% restocking fee for changed_mind) = 1,615 cents
    • Calculation: 2 units × 1,615 = 3,230 cents
  • Restocked:

    • 1 P-CAB unit as sellable (received 2026-07-22, grade resellable)
    • 1 P-CAB unit as damaged (received 2026-07-25, grade damaged)
  • Status: Kept OPEN as required, pending receipt of the 3rd unit still in transit

❌ RMA-805, RMA-812, RMA-813: CANNOT BE FIXED

The issues correctly identify that these RMAs were refunded via the wrong method:

  • RMA-805: Requested 2026-06-25 (15 days after 2026-06-10 ship date) — within 30-day window, should be card
  • RMA-812: Requested 2026-07-08 (28 days after 2026-06-10 ship date) — within 30-day window, should be card
  • RMA-813: Requested 2026-07-24 (30 days after 2026-06-24 ship date) — within 30 days (not "more than 30"), should be card

However, these RMAs are already CLOSED and the customers have already received their refunds as store credit. Per domain policy: "Money already refunded on an order is never refunded again." There are no tools available to reverse completed refunds, remove store credit, or reopen closed RMAs. These represent prior operational errors that cannot be corrected with the available tools and policy constraints.
