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 worked the nine flight-change requests: Q-301 to Q-305 and Q-307 to Q-310. Each customer is rebooked in their own cabin, every fee is its own ledger entry, and each request is resolved with a note saying what they were charged and why.
I left Q-306 (R5206, a cancellation) for the cancellations team. I didn't touch any other booking.
The plan assumed today is 2026-07-28. That's the date the bulletin tool reports and it fits "requests from yesterday". My environment header said 2026-10-06, which would have made every bulletin expired. I went with the tool's date.
Before acting I re-checked the bulletins, fare rules, tiers, reservation histories, ledgers, flight status and seats. All of it matched the plan.
| Request | Reservation | New flight | Charged |
|---|---|---|---|
| Q-301 Ines | R5201 | AA210 → DL542 (Aug 6) | $0, covered by PB-14 |
| Q-302 Jonah | R5202 | AA660 → AA664 (Aug 7) | $110: $75 change fee + $35 fare difference |
| Q-303 Kim | R5203 | AA662 → AA664 (Aug 7) | $175: $150 change fee (PB-16) + $25 fare difference |
| Q-304 Lena | R5204 | UA88 → UA90 (Aug 9) | $35 fare difference; change fee waived |
| Q-305 Max | R5205 | AA214 → AA216 (Aug 8) | $85: $75 change fee + $10 fare difference |
| Q-307 Oscar | R5207 | AA212 → AA218 (Aug 8) | $0, covered by PB-14A (he had offered to pay) |
| Q-308 Petra | R5208 | AA660 → AA662 (Aug 5) | $75 flat same-day fee (PB-12) |
| Q-309 Quinn | R5209 | AA1402 → AA1406 (ORD–BOS leg only; UA88 kept) | $0, covered by PB-14 |
| Q-310 Ravi | R5210 | AA210 → AA216 (Aug 8) | $105: $75 change fee + $30 fare difference |
Charged despite expecting a waiver: Jonah's, Kim's, Max's and Ravi's notes say plainly why no waiver applied.
- Jonah: the Boston waiver expired Jul 15, and the Chicago waiver only covers ORD travel.
- Kim: PB-09 expired.
- Max: he booked Jul 26, after the Jul 24 cutoff.
- Ravi: his one free move was already used on Jul 26.
- Quinn's $0 is a judgment call. It relies on PB-14 covering a single segment of a connecting trip. If that reading is rejected, the fallback is PB-12's $75 change fee.
- Notifications: I sent no separate emails or texts. The customers will see only the resolution notes.
