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

Dana's unshipped order O-1001 now has her new address. Her in-transit order O-1002 was not changed.

O-1001 (not shipped, address updated)

  • Placed 2026-07-20, status pending. Neither line has shipped: 1 × P-KEY and 2 × P-CAB.
  • Before: 12 Alder Lane, Bristol BS1 4TR, UK
  • After: 7 Quarry Rise, Sheffield S11 8XZ, UK
  • A read-back after the change showed the new address. The status, lines, payments and refunds were the same as before.

O-1002 (in transit, not affected)

  • Placed 2026-07-05, status shipped. Its one line, 1 × P-MON, shipped on 2026-07-07.
  • Its address is still 88 Old Mill Road, Bristol BS3 2QQ, UK. Store policy says a shipped order's address can't be changed.
  • Both workers checked this. The read-only check may have run while the update was happening. The worker that made the update re-read O-1002 afterwards and found the address, status, shipping date and money figures the same as before.

Nothing else was touched: no other orders, lines, products, or her customer profile.

For you to follow up on

  • O-1002 is going to her old Bristol address. We can't redirect it from here. If she can't collect it there, she'll need to contact the carrier or arrange a return once it arrives.
  • Her customer profile was not updated, because that wasn't part of this request. Future orders may still default to the Bristol address unless the profile is changed separately.
  • Both workers saw a date mismatch: the store system says 2026-07-25, but their environment says 2026-10-06. It didn't affect this change.
