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.
  • Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.

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 the open cancellation requests. Here's a summary of what was processed:

Summary of Cancellation Processing

8 cancellation requests resolved:

  1. Q-401 (R7101 - Nora Quinn): Chicago trip cancelled. $270 refunded to Visa card (economy fare minus $50 service fee).
  2. Q-402 (R7102 - Omar Said): Seattle trip cancelled. $210 full refund to Mastercard (booked within 24 hours, no fees apply).
  3. Q-403 (R7103 - Paula Reyes): LA trip cancelled. $260 travel credit issued (trip insurance covers; payment card is closed so credit issued instead).
  4. Q-404 (R7104 - Quentin Hale): New York trip cancelled. $200 refunded to Visa card (economy fare minus service fee; $100 goodwill refund already issued).
  5. Q-405 (R7105 - Rhea Stone): Denver trip cancelled. No refund (basic economy is non-refundable; no insurance; not within 24-hour booking window).
  6. Q-406 (R7106 - Sam Ortiz): Boston trip cancelled. $248 travel credit issued (trip insurance doesn't cover; cancellation is within 14 days of departure).
  7. Q-408 (R7108 - Uma Patel): Return flight cancelled. $120 refunded to Visa card (outbound already flown; only unflown segment is refundable at segment fare minus service fee).
  8. Q-409 (R7110 - Victor Hugo): Seattle trip cancelled. $320 travel credit issued (customer's choice; no service fee applies).

All cancellations were processed according to the refund policy rules, payment instruments were verified, and customers were notified with clear explanations of what they're 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.
