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
I added two checked bags to Rosa Mendel's reservation R1042 (SFO→SEA) and charged her $45.00 for them.
- Bags: She had 1 bag and now has 3. That is the most a reservation can hold, so both requested bags fit.
- Free allowance: Economy includes 1 free bag, and her Silver status adds 1 more. That makes 2 free bags, so the first 2 bags cost nothing.
- Fee: Only the 3rd bag is chargeable. The published price for the first chargeable bag is $45.00, and I charged that as one baggage_fee entry (L1).
- Check: I re-read the reservation and ledger. R1042 shows 3 bags and exactly one fee entry of $45.00.
Date issue: The reservation lists the flight AS420 on 2026-08-11, which is before today's date of 2026-10-04. The system still shows the flight as "scheduled" and the reservation as confirmed. I went ahead because the task and the policy didn't block it, but someone should confirm the travel date is correct.
