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 task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s full toolset.

The call-by-call replay is not published for this run. Traces are large, so the repository keeps 9 of this run set’s 900 and leaves the rest out; the score, phases and final answer on this page come from the committed run record.

Final answer

Two checked bags have been added to Rosa Mendel's reservation R1042, bringing her to 3 bags, and she has been charged $45.00. However, her flight date may already be in the past, and that needs to be checked before this is treated as final.

How the charge was worked out

  • Her free allowance is 2 bags: 1 included with Economy and 1 more from her silver frequent-flyer status.
  • She already had 1 bag. Adding 2 brings her to 3, which is 1 bag over the allowance.
  • The published fee for the first bag over the allowance is $45.00. It was recorded as a single baggage fee entry (L1), the only ledger entry on the reservation.
  • 3 bags is the most a reservation can hold, so she can't add any more.

Open issue: the flight date
Her flight, AS420 from SFO to SEA, is dated 2026-08-11, which is almost two months before today (2026-10-04). The system still shows the flight as "scheduled" and her booking as confirmed, so the worker went ahead. That combination doesn't add up: either the date on record is wrong or the status is stale.

If she has already flown, she was charged $45.00 for bags on a trip that's over. Someone should confirm her travel date with her before treating this as settled. If the flight has already happened, the bag change and the $45.00 charge would need to be reversed, and that has not been done.

Cost excludes judge calls, which are tracked separately so a scoring model never flatters or penalises an architecture. Every figure on this site is read from results/ at build time.
