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-verify.planThe planner’s reply was read through its schema and held at least one step.
- Every verdict was read: heldplan-execute-verify.verdictsEvery review round ended with a verdict read from the schema reply, not a default.
- The loop did what its verdicts said: heldplan-execute-verify.loopEvery verdict that called for a revision got one, and nothing was revised without such a verdict.
- Each call was shown the right tools: heldplan-execute-verify.toolsThe planner was shown no tools, the verifier the read-only ones, and the executor and reviser the full toolset.

Final answer
Marcus, I've cancelled R3311 (AA660, SFO→Boston, 2026-08-05). You're getting the full $248.00 back as travel credit, not on your card.
- Why credit and not card: Your fare is Basic Economy, which isn't refundable on its own. Your trip insurance does override that, but only if you cancel at least 14 days before departure. The refund policy shows today as 2026-07-28, which is 8 days before the flight. Inside that window, the insurance turns the fare into travel credit and no money goes back to your card.
- Fee: The $50 cancellation service fee is waived because you're a Platinum member. The credit is the full $248.00.
- Ledger: There is one entry, L1, for $248.00 as travel credit. I checked the ledger after settling and there are no other entries.
The policy tool's date (2026-07-28) differs from the date in my task context (2026-10-05). I followed the policy tool's date, and the flight still showed as scheduled. I did not touch any other bookings.
