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

All 13 passengers on AA918 are rebooked on flights that are still operating, and each has been notified once. No change fees or fare differences were charged. There were no bulletins in effect and no queued requests, so nothing was overridden and no request needed resolving.

Priority order was platinum, then gold, silver, none, with earlier booking date breaking ties. The Takeda/Mensah group (G-7) was handled as one unit at gold priority.

  • Upgrades: Iris (platinum) and Lea (gold) each travel alone on a single flight. Their own cabin was full on a flight that gets them to Chicago sooner than any open seat in their cabin, so each moved up one cabin. Nobody else was upgraded.
  • Dev and Mo: Neither could make their Boston connection, because no economy seat reached Chicago before the 15:30 departure. Their onward leg was moved to AA1410 on 4 Aug. They land in Boston 17h30m later than scheduled and on a later date, so they get the full compensation plus a hotel voucher.
  • Grace's voucher: Her compensation was capped at the $240 fare she paid, instead of the standard 30000.
  • Not re-protected: Nobody was left without a seat.
