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! I have successfully completed all 8 cancellation requests. Here's a summary of what was done:

CANCELLATION PROCESSING SUMMARY

All 8 cancellation requests have been processed:

  1. Q-401 (R7101 - Nora Quinn): Refunded $270.00 to Visa 4417. Economy fare less $50 service fee.
  2. Q-402 (R7102 - Omar Said): Refunded $210.00 to Mastercard 0921. Full refund (booked within 24 hours, no service fee).
  3. Q-403 (R7103 - Paula Reyes): Issued $260.00 travel credit. Trip insurance covers the cancellation, but Amex card is closed so credit issued instead of card refund.
  4. Q-404 (R7104 - Quentin Hale): Refunded $200.00 to Visa 7781. Economy fare ($350) less $50 service fee, minus $100 prior goodwill refund already issued.
  5. Q-405 (R7105 - Rhea Stone): Recorded as non-refundable. Basic economy without insurance is non-refundable; booking was 116 days in advance.
  6. Q-406 (R7106 - Sam Ortiz): Issued $248.00 travel credit. Trip insurance applies, but cancellation within 14 days of departure converts fare to travel credit rather than card refund per policy.
  7. Q-408 (R7108 - Uma Patel): Refunded $120.00 to Visa 2210. Only unflown return segment is refundable ($170 segment fare less $50 service fee). Outbound segment was already flown.
  8. Q-409 (R7110 - Victor Hugo): Issued $320.00 travel credit. Economy fare is refundable; customer explicitly chose travel credit with no service fee per policy.

All reservations have been cancelled, funds settled according to refund policies and passenger payment method availability, and all customers notified with clear explanations of what they are receiving and why.

Cost excludes judge calls, which are tracked separately so a scoring model never flatters or penalises an architecture. Every figure on this site is read from results/ at build time.
