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 plan was a plan: heldplan-execute-verify.planThe planner’s reply was read through its schema and held at least one step.
  • Every verdict was read: heldplan-execute-verify.verdictsEvery review round ended with a verdict read from the schema reply, not a default.
  • The loop did what its verdicts said: heldplan-execute-verify.loopEvery verdict that called for a revision got one, and nothing was revised without such a verdict.
  • Each call was shown the right tools: heldplan-execute-verify.toolsThe planner was shown no tools, the verifier the read-only ones, and the executor and reviser the full toolset.

Final answer

The issue was valid. The vouchers had never been issued, and they are now. I left the re-protection bookings alone.

Before issuing, I checked each amount against the original AA918 arrival (13:40), the new itineraries, the fares paid, and the bulletin list, which was empty.

Passenger (reservation)Vouchers issuedWhy
Ben Okafor (R6102)V11: 15000 compensationArrives 5 hours late.
Dev Mehta (R6104)V12: 30000 compensation; V13: 18000 hotelReaches Boston the next day, about 17.5 hours later than scheduled.
Mo Farah (R6113)V14: 30000 compensation; V15: 18000 hotelSame itinerary as Dev. I did not check Mo's original connection separately, but his booking history shows no changes since booking.
Hugo Brandt (R6108)V16: 30000 compensationArrives about 10 hours late, but on the same date, so no hotel voucher.
Grace Liu (R6107)V17: 24000 compensation; V18: 18000 hotelArrives the next day. Compensation is capped at her 24000 fare.
Ana Ruiz (R6101)V19: 30000 compensation; V20: 18000 hotelArrives the next day, more than 6 hours late.

Each of these six passengers has been told by message what voucher they received and why. Their itineraries did not change.
