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

I updated the order that hadn't shipped (O-1001) to Dana's new address. Her order in transit (O-1002) was not changed.

O-1001: address updated

  • Status: pending. Neither line has shipped (1 × P-KEY, 2 × P-CAB).
  • Previous address: 12 Alder Lane, Bristol BS1 4TR, UK
  • New address: 7 Quarry Rise, Sheffield S11 8XZ, UK
  • The order was read again after the change. The new address is saved, the status is still pending and the lines are the same.

O-1002: in transit, not changed

  • Status: shipped. Its one line (1 × P-MON) went out on 2026-07-07.
  • Address on file: 88 Old Mill Road, Bristol BS3 2QQ, UK, which is not the new address.
  • Two separate checks confirmed this, including one made after O-1001 was updated. The order has no refunds or other changes.

Nothing else was changed. Nothing was cancelled, refunded, dispatched or restocked, and her customer profile was not edited.

A note on the two reports: the read-only check found O-1001 still showing the old address. That check most likely ran before the update was saved. The worker that made the change read O-1001 again afterwards and confirmed the new address, so I don't treat this as a real conflict.

Worth telling Dana: her two orders had different addresses. The parcel in transit (O-1002) is going to 88 Old Mill Road, Bristol, not 12 Alder Lane. Because it has shipped, its address cannot be changed, so it will go to Old Mill Road. If that isn't where she lives now, she may need to arrange to collect it there.

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.
