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 task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

Final answer

Final Answer

Reservation R3311 for Marcus Bell has been successfully cancelled. However, the settlement follows the airline's refund policy, not his request.

Settlement Details:

  • Original booking cost: $248.00
  • What Marcus receives: $198.00 travel credit (not a refund to his card)
  • Deduction: $50.00 cancellation service fee

Why this outcome: Although Marcus purchased trip insurance, the airline's refund policy requires cancellations to be made at least 14 days before departure to receive a refund to the original payment method. His cancellation occurs only 8 days before the August 5, 2026 flight, making it ineligible for a card refund. Under the policy, the trip insurance converts the fare to travel credit rather than a refund, and the $50 cancellation service fee is applied per fare rules.

Status: The reservation is closed out, and $198.00 in travel credit has been recorded on Marcus Bell's account per the domain policy requirements for financial settlement of cancelled bookings.
