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 worked all nine open flight-change requests. Each change is booked, its fees are charged, and the request is resolved with a note to the customer. I left Q-306 (R5206, a cancellation) alone because it isn't a flight change.

One thing conflicts: the system date is 2026-10-05, but the bulletins say today is 2026-07-28. I used 2026-07-28, which matches the requests being "from yesterday".

RequestChangeChargedWhy
Q-301 InesDL542, 6 Aug$0Chicago waiver PB-2026-14: fee and fare difference waived
Q-302 JonahAA664, 7 Aug$75 fee + $35 fare differenceBoston trip, so the Chicago waiver doesn't apply
Q-303 KimAA664, 7 Aug$150 fee + $25 fare differenceHurricane waiver PB-2026-09 expired 15 Jul; basic economy fee is $150 under PB-2026-16
Q-304 LenaUA90, 9 Aug$35 fare differenceFee waived (waiver, and gold). Waiver doesn't cover basic economy fare differences
Q-305 MaxAA216, 8 Aug$75 fee + $10 fare differenceBooked 26 Jul, after the 24 Jul waiver cutoff
Q-307 OscarAA218, 8 Aug$0Platinum window extends to 5 Aug (PB-2026-14A)
Q-308 PetraAA662, 5 Aug$75Same-day flat fee (PB-2026-12), no fare difference
Q-309 QuinnAA1406, 3 Aug (Chicago–Boston leg only)$0The Chicago waiver costs less than the same-day fee, so PB-2026-17 applies it. The connection still works.
Q-310 RaviAA216, 8 Aug$75 fee + $30 fare differenceHis one free waiver move was already used on 26 Jul

All changes kept the cabin each customer booked.

I did not send separate emails. The explanation is in each request's resolution note.
