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
Final Answer
I've corrected the settlement for reservation R3311. The issue has been fixed:
What Marcus Bell now receives: $248.00 travel credit (the full amount he paid)
Why the correction: Marcus Bell is a Platinum tier frequent flyer. The refund policy explicitly waives the $50 cancellation service fee for Platinum members. The previous attempt incorrectly charged this fee, reducing his travel credit to $198.00.
Action taken: I issued an additional $50.00 travel credit to bring the total settlement to the correct amount of $248.00.
The ledger now correctly reflects:
- Initial travel credit: $198.00
- Additional travel credit (correction): $50.00
- Total travel credit: $248.00
Marcus can use this full $248.00 credit toward any future flight with the airline.
