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.
- All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
- The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
- Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

Final answer
I've worked all nine flight-change requests from 27 July (Q-301 to Q-305 and Q-307 to Q-310) and resolved each one with a note to the customer. Before each change I re-checked the reservation, its change history, the passenger's tier and the new flight. Every new flight is scheduled with seats in the customer's own cabin, and no booking changed cabin.
| Req | Change | Charged | Why |
|---|---|---|---|
| Q-301 R5201 | AA210 3 Aug → DL542 6 Aug | nothing | The Chicago weather waiver (PB-2026-14) covers it, so there's no change fee or fare difference |
| Q-302 R5202 | AA660 5 Aug → AA664 7 Aug | 7500 change fee + 3500 fare difference | It's a Boston trip, so the Chicago waiver doesn't apply and normal economy rules do |
| Q-303 R5203 | AA662 5 Aug → AA664 7 Aug (basic economy) | 15000 change fee + 2500 fare difference | The hurricane waiver he cited (PB-2026-09) ended on 15 July. The basic economy change fee is now 15000 (PB-2026-16), and silver members aren't exempt |
| Q-304 R5204 | UA88 3 Aug → UA90 9 Aug (basic economy) | 3500 fare difference | The waiver drops the change fee, but basic economy still pays the fare difference |
| Q-305 R5205 | AA214 4 Aug → AA216 8 Aug | 7500 change fee + 1000 fare difference | Booked on 26 July, after the waiver's 24 July cutoff |
| Q-307 R5207 | AA212 5 Aug → AA218 8 Aug | nothing | The amendment (PB-2026-14A) extends the waiver to 5 August for platinum members, so he pays nothing even though he offered to |
| Q-308 R5208 | AA660 → AA662, same day 5 Aug | 7500 change fee | The flat same-day fee (PB-2026-12) is cheaper than normal rules, which would add a 1300 fare difference |
| Q-309 R5209 | Only the Chicago–Boston flight moved: AA1402 → AA1406 (dep 19:55); UA88 kept | nothing | The waiver covers it. The connection is valid: UA88 lands at 12:25 |
| Q-310 R5210 | AA210 3 Aug → AA216 8 Aug | 7500 change fee + 3000 fare difference | He already used his one waiver move on 26 July (AA214 → AA210) |
Each charge is its own ledger entry (L1 to L10). No money went back to anyone, so the state of the payment cards didn't matter.
What I didn't touch:
- Q-306 (R5206): this is a cancellation, not a flight change, so I left it for the team that owns it.
- Q-311 and Q-312: two new change requests arrived today (28 July). They aren't from yesterday, so I left them open and didn't touch their bookings.
