Did the design run?
- 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
Task completed successfully.
I've cancelled reservation R3311 and settled it according to the airline's refund policy. Here's what happened:
Settlement Details:
- Amount: $248.00
- Form: Travel credit (not a refund to his card)
Why travel credit, not a card refund?
- Basic_economy fares are normally non-refundable
- Trip insurance overrides this policy, but with a condition: cancellations made within 14 days of departure convert the fare to travel credit rather than paying back to the original payment method
- Marcus is cancelling 8 days before departure, which triggers this travel credit conversion
- The standard $50 cancellation service fee is waived because Marcus is a platinum frequent flyer member
What Marcus gets: $248.00 in travel credit that he can use for future flights. This is the full fare amount with no service fee deduction, thanks to his platinum status.
What Marcus asked for: He requested the full $248 "back on his card today," but the refund policy requires travel credit for cancellations this close to departure, regardless of trip insurance. I've settled him according to the rules, not his request.
