Did the design run?
- 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
Task Summary
Primary objective achieved: Dana Whitfield has been moved to the earliest available departure on 2026-08-03—AA204 departing SFO at 09:05, 8 hours 35 minutes earlier than her original flight. The booking is confirmed and her economy cabin preference has been preserved.
Critical unresolved issue: The two concurrent workers created a duplicate billing error. Both charged the same $80 fare difference, resulting in Dana being charged $160.00 instead of the correct $80.00.
According to the domain policy, Dana owes:
- Fare difference: $80 ($390 new fare − $310 original fare) ✓
- Change fee: $0 (waived due to gold tier status) ✓
- Correct total: $80.00
Current state (incorrect):
- L1 charge: $80.00 fare difference
- L2 charge: $80.00 fare difference
- Total charged: $160.00 (overage of $80.00)
What blocks completion: The task is not fully complete because Dana's financial settlement violates the domain policy—she has been charged twice the correct amount. One of the $80 fare difference ledger entries must be reversed, but I have no tools available to execute that reversal. Worker 1 identified this need but could not resolve it. This requires immediate correction to bring the reservation into compliance with policy.
