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 moved all nine customers to the flights they asked for and resolved each request with a note stating what they were charged and why. Q-306, the Boston cancellation, is not a flight change, so I left it for the team that owns it.

I used the queue's date of 2026-07-28 to decide which bulletins were in effect. The system prompt said 2026-10-06, which conflicts with it.

RequestPassengerNew flightCharged
Q-301Ines DuarteDL542, 6 Aug$0. The Chicago waiver (PB-2026-14) covers her.
Q-302Jonah PikeAA664, 7 Aug$110: $75 change fee + $35 fare difference. The waiver he saw covers Chicago, not his Boston flight.
Q-303Kim SeoAA664, 7 Aug$175: $150 basic economy change fee + $25 fare difference. The Boston hurricane waiver (PB-2026-09) had expired and only covered July travel. The $150 fee comes from PB-2026-16, which overrides the $125 in the fare rules.
Q-304Lena OrtizUA90, 9 Aug$35 fare difference. The change fee is waived, but the Chicago waiver still collects fare differences on basic economy.
Q-305Max WeberAA216, 8 Aug$85: $75 change fee + $10 fare difference. His ticket was issued 26 Jul, after the 24 Jul cutoff for the Chicago waiver.
Q-307Oscar LundAA218, 8 Aug$0. As a platinum member his waiver window runs through 5 Aug (PB-2026-14A), so his 5 Aug flight is covered.
Q-308Petra NovakAA662, 5 Aug$75. This is the flat same-day fee (PB-2026-12), with no fare difference.
Q-309Quinn AdlerChicago–Boston leg moved to AA1406, 3 Aug$0. Both the Chicago waiver and the same-day bulletin apply, and PB-2026-17 says to use whichever costs the customer least.
Q-310Ravi ShahAA216, 8 Aug$105: $75 change fee + $30 fare difference. His reservation had already used its one free waiver move on 26 Jul.

Ravi's request asked for the waiver, so I told him in the resolution note why he was charged. The action reviewer initially blocked a free move for him and I rebooked it at the normal rates.

Each fee is its own ledger entry (L1–L10). Every change kept the cabin the customer booked.
