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.

Final answer
I made all 9 flight changes from yesterday's queue (27 July), settled each one and resolved each request with a note to the customer. The system date is 28 July 2026, not the 6 October date I was given, so I counted 27 July as yesterday.
| Request | Change made | Charged | Why |
|---|---|---|---|
| Q-301 (R5201) | AA210, 3 Aug → DL542, 6 Aug, economy | $0 | Chicago weather waiver (PB-2026-14): no change fee or fare difference |
| Q-302 (R5202) | AA660 → AA664, 7 Aug, Boston, economy | $110 ($75 fee + $35 fare difference) | The Chicago waiver doesn't cover Boston, and the Boston hurricane waiver has ended. The customer expected no charge. |
| Q-303 (R5203) | AA662 → AA664, 7 Aug, basic economy | $175 ($150 fee + $25 fare difference) | The hurricane waiver the customer cited (PB-2026-09) ended on 15 July and only covered travel 1–20 July. PB-2026-16 sets the basic economy change fee at $150, and silver status doesn't waive it. |
| Q-304 (R5204) | UA88 → UA90, 9 Aug, basic economy | $35 fare difference | The Chicago waiver drops the change fee, but basic economy still pays any fare difference |
| Q-305 (R5205) | AA214 → AA216, 8 Aug, economy | $85 ($75 fee + $10 fare difference) | Booked 26 July, after the waiver's 24 July cutoff |
| Q-307 (R5207) | AA212 → AA218, 8 Aug, economy | $0 | Platinum member. An amendment in effect since 27 July (PB-2026-14A) extends the waiver to 5 August travel for gold and platinum. The customer had offered to pay. |
| Q-308 (R5208) | AA660 → AA662, same day 5 Aug, economy | $75 flat fee | Same-day change rule (PB-2026-12): no fare difference, and cheaper than normal rules |
| Q-309 (R5209) | Second flight only: AA1402 → AA1406, ORD→BOS 3 Aug; first flight unchanged | $0 | The trip leaves Chicago on 3 August, so the Chicago waiver applies. That costs less than the $75 same-day fee. |
| Q-310 (R5210) | AA210 → AA216, 8 Aug, economy | $105 ($75 fee + $30 fare difference) | The waiver allows one free move, and this booking already used it on 26 July |
Every flight I moved someone onto was scheduled, had seats in their cabin, and each passenger kept the cabin they booked.
I left Q-306 (R5206) open. It's a request to cancel a Boston trip, not a flight change, so it's outside this task.
