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.
- Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.
Phases
Drawn from the phase records: timing and cost per call, no tool calls or messages.

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 address on O-1001, the order that hasn't shipped. O-1002, the one in transit, is unchanged.
- O-1001 (pending): the shipping address changed from 12 Alder Lane, Bristol BS1 4TR, UK to 7 Quarry Rise, Sheffield S11 8XZ, UK.
- O-1002 (shipped 2026-07-07): I left it alone, as the handbook says an address on a shipped order is never changed. I read it again after the update. It still shows 88 Old Mill Road, Bristol BS3 2QQ, UK, with the same status and no refunds.
The parcel for O-1002 is going to the old Bristol address. If Dana wants it redirected, she'd have to arrange that with the carrier.
