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.
  • Every state change was reviewed: heldgated-execute.reviewedEvery call that changed the world had been allowed by a review before it ran, counted from the world’s own journal.
  • Every decision was read: heldgated-execute.decisionsEvery review that ran to its end gave its decision through the schema; an unreadable one is a denial.
  • Each call was shown the right tools: heldgated-execute.toolsThe executor was shown the task’s full toolset and each reviewer the read-only tools.

Final answer

I've rebooked all 13 reservations from cancelled AA918 under the irregular-operations rules. Nobody paid a change fee or fare difference, and nobody was moved to a lower cabin. I issued the compensation and hotel vouchers owed and messaged each passenger once with their new itinerary.

There were no bulletins in effect and nothing on the ledger beforehand. No one's tier had changed, so I used current tiers.

Something to check: today's system date is 2026-10-06, two months after the 2026-08-03 flight date. I did what the task asked, but the new itineraries and vouchers are for dates that have already passed. Operations may want to confirm the records are meant to be backdated like this.

The table is in priority order: platinum, then gold, silver and no tier, earliest booking first within each tier. AA918 was due into Chicago O'Hare (ORD) at 13:40.

  • Upgrades: Iris and Lea were the only ones moved up, one cabin each. Both are platinum or gold and travelling alone. Their own cabin was full on a flight that gets in sooner than anything still open in that cabin.
  • No upgrade for Ben: there was no seat one cabin up on any earlier flight, so he went to the first open economy seat on DL512.
  • Jun and Kofi: they kept their own cabin and the gold priority of the higher-tier member. They were not split or upgraded.
  • Boston connections: Dev's and Mo's original 15:30 flight to Boston can't be reached anymore. Every economy seat into Chicago before AA210 was taken, and there are no later flights to Boston that evening, so the overnight connection is the soonest arrival.
  • Next-day passengers: Grace and Ana are on 08-04 because every economy seat on 08-03 was gone by the time their turn came.
