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

I cancelled R3311 and closed it out financially with $248.00 of travel credit, not the refund to Marcus's card that he asked for. This rests on a single worker report, and one date discrepancy in it is unresolved.

What was done (per the worker report)

  • R3311 (AA660, 2026-08-05 to Boston) was cancelled and the seat released.
  • A single ledger entry (L1) issued $248.00 as travel credit.
  • The $50 cancellation fee was waived because Marcus is a platinum member, so the credit is the full $248.00.

Why credit and not a card refund

  • The fare is basic economy, which is non-refundable on its own.
  • His trip insurance returns money to the card only if the cancellation is made at least 14 days before departure.
  • The refund policy for R3311 reported today's date as 2026-07-28, which is 8 days before departure. That is inside the 14-day window, so the insurance converts the fare to travel credit.
  • The 24-hour full-refund rule doesn't apply, because the booking was made on 2026-04-11.

Unresolved discrepancy

  • The environment's date is 2026-10-06, but the refund policy tool reported 2026-07-28.
  • The worker used the policy tool's date and said the outcome is the same on either date. I can't confirm that. If today really is 2026-10-06, the 2026-08-05 departure is already in the past.
  • The worker said AA660 still showed as scheduled with no flown segments, which fits the policy date better. No worker resolved the conflict.
  • Someone should check the date and the reservation's status.

What to tell Marcus
He is getting $248.00 in travel credit, not money back on his card. His fare is non-refundable, and his insurance pays to the card only when the cancellation is at least 14 days before departure. His trip was inside that window.
