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.planThe planner’s reply was read through its schema and held at least one step.
  • Each call was shown the right tools: heldplan-execute.toolsThe planner was shown no tools and the executor the task’s full toolset.

Final answer

Perfect! I have completed all 8 open cancellation requests in the service queue. Here's a summary of what was processed:

Summary of Completed Cancellations

  1. Q-401 (R7101) - Nora Quinn: Cancelled. $270.00 refunded to Visa ending 4417 (economy fare minus $50 service fee).
  2. Q-402 (R7102) - Omar Said: Cancelled. $210.00 full refund to Mastercard ending 0921 (booked within 24 hours, no service fee).
  3. Q-403 (R7103) - Paula Reyes: Cancelled. $260.00 issued as travel credit (trip insurance covered, but payment method Amex 3005 was closed).
  4. Q-404 (R7104) - Quentin Hale: Cancelled. $200.00 refund issued plus prior $100.00 goodwill refund = $300.00 total (economy fare with service fee).
  5. Q-405 (R7105) - Rhea Stone: Cancelled. Closed out as non-refundable (basic economy with no trip insurance).
  6. Q-406 (R7106) - Sam Ortiz: Cancelled. $248.00 issued as travel credit (trip insurance applies, but less than 14 days before departure converts to credit rather than card refund).
  7. Q-408 (R7108) - Uma Patel: Cancelled. $120.00 refund to Visa ending 2210 (only unflown return segment refundable after outbound flight had flown).
  8. Q-409 (R7110) - Victor Hugo: Cancelled. $320.00 issued as travel credit (customer's explicit choice, so no service fee deducted).

All cancellations have been recorded in the ledger, reservations cancelled, and customer requests resolved 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.
