Did the design run?

every check held
  • 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 task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

Final answer

All 9 flight-change requests from 27 July were worked and resolved. Each customer is on the flight they asked for, in the cabin they booked, and seat availability was checked before each booking. One related request was left open on purpose (Q-306), and there is a date discrepancy you should check, covered below.

RequestBookingChangeChargedBasis
Q-301R5201AA210 3 Aug → DL542 6 Aug, Chicago, economy$0The Chicago weather waiver (PB-2026-14) covers the change fee and the $50 fare difference.
Q-302R5202AA660 5 Aug → AA664 7 Aug, Boston, economy$110 ($75 change fee + $35 fare difference)The customer expected a waiver, but the current one covers only Chicago. The Boston waiver ended 15 July.
Q-303R5203AA662 5 Aug → AA664 7 Aug, Boston, basic economy$175 ($150 change fee + $25 fare difference)The cited Boston waiver (PB-2026-09) expired 15 July and covered only 1–20 July travel. The basic economy fee is $150 under PB-2026-16. Silver members are not exempt.
Q-304R5204UA88 3 Aug → UA90 9 Aug, Chicago, basic economy, gold member$35 fare differenceThe Chicago waiver removes the change fee, but it still collects fare differences on basic economy.
Q-305R5205AA214 4 Aug → AA216 8 Aug, Chicago, economy$85 ($75 change fee + $10 fare difference)Ticketed 26 July, after the waiver's 24 July cutoff.
Q-307R5207AA212 5 Aug → AA218 8 Aug, Chicago, economy, platinum member$0The customer offered to pay, but the 27 July amendment (PB-2026-14A) extends the waiver to 5 Aug for gold and platinum members. The fee and the $65 fare difference are waived.
Q-308R5208AA660 → AA662, same day 5 Aug, Boston, economy$75 change feeThe same-day change rule (PB-2026-12) charges a flat fee with no fare difference. That is cheaper than the standard $88, and PB-2026-17 says the cheaper rule applies.
Q-309R5209Second leg only: AA1402 → AA1406, Chicago–Boston, 3 Aug$0The Chicago waiver is cheaper than the $75 same-day fee. The first leg is unchanged, and the new leg leaves 7.5 hours after it lands, so the connection is valid.
Q-310R5210AA210 3 Aug → AA216 8 Aug, Chicago, economy$105 ($75 change fee + $30 fare difference)The waiver allows one free change, and this booking already used it on 26 July.

Not done:

  • Q-306 (R5206) is still open. It is a cancellation, not a flight change, so it is outside this task and was left for the team that handles cancellations.

Needs your attention: the date.

  • This session gives today as 6 October 2026, but the airline system reported 28 July 2026 when the work was done.
  • The worker used the system date. That matches "yesterday" being 27 July, when the requests arrived. It also fits that the new flights (3–9 August) could still be booked with open seats.
  • If 6 October is the real operating date, the result changes. Every bulletin applied except PB-2026-12 (same-day changes) and PB-2026-16 (basic economy fee) would have expired. The waived and reduced charges for Q-301, Q-304, Q-307, Q-308 and Q-309 would then be wrong.
  • Please confirm which date is correct. All changes and charges above are already in place.

Not reported: The report doesn't say whether each change fee and fare difference was recorded as a separate ledger entry, as the handbook requires. Spot-checking the ledger would confirm it.
