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.
- Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.
Phases
Drawn from the phase records: timing and cost per call, no tool calls or messages.

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer
I added two checked bags to R1042, which now holds 3, and charged Rosa Mendel $45.00 for them.
- Free allowance: Rosa flies economy, which includes 1 free bag. Her silver frequent-flyer tier adds 1 more, so she gets 2 free bags.
- Fee: With 3 bags, only 1 is over the allowance. That bag is the first chargeable one, at $45.00. I recorded it as a single baggage_fee entry (L1), so she wasn't charged $90 for both new bags.
- Cap: 3 bags is the most a reservation can hold, so she can't add any more.
- Date discrepancy: Today is 2026-10-04, but the reservation shows flight AS420 on 2026-08-11 as "scheduled". I went ahead because the system lists the flight and reservation as active, but the date may be worth checking.
