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.
  • Every state change was reviewed: heldgated-execute.reviewedEvery call that changed the world had been allowed by a review before it ran, counted from the world’s own journal.
  • Every decision was read: heldgated-execute.decisionsEvery review that ran to its end gave its decision through the schema; an unreadable one is a denial.
  • Each call was shown the right tools: heldgated-execute.toolsThe executor was shown the task’s full toolset and each reviewer the read-only tools.

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've put Dana Whitfield's new address on the order that hasn't shipped. The order already in transit is unchanged.

  • O-1001 (not shipped yet): The address changed from "12 Alder Lane, Bristol BS1 4TR, UK" to "7 Quarry Rise, Sheffield S11 8XZ, UK". The order is still pending, with nothing else changed.
  • O-1002 (in transit): It shipped on 2026-07-07, and I didn't edit it because store rules never allow changing the address on a shipped order. I checked it again afterwards: the address is still "88 Old Mill Road, Bristol BS3 2QQ, UK", it's still marked shipped and there are no refunds.

Two things to be aware of:

  • Different old addresses: Her two orders had different old addresses. O-1002 is going to 88 Old Mill Road, which isn't the Bristol address that was on O-1001. If she no longer lives at either one, she may need to arrange with the courier to pick up or redirect that parcel. We can't change it from here.
  • Date mismatch: The store system gives today's date as 2026-07-25, but my environment says 2026-10-06. This didn't affect the address change, but the system clock may be worth checking.

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.
