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.
  • All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
  • The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
  • Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

Phases

Proposal 1 (policy-first): 0.0s to 20.3s, finished, 4 tool calls, $0.024
Proposal 2 (state-first): 0.0s to 16.5s, finished, 4 tool calls, $0.018
Proposal 3 (outcome-first): 0.0s to 16.6s, finished, 4 tool calls, $0.018
Select: 20.3s to 50.4s, finished, 0 tool calls, $0.020
Execute: 50.4s to 1m 6s, finished, 5 tool calls, $0.025

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.

Summary

✅ Task completed successfully

What I did:

  1. Updated order O-1001 (pending/not shipped): Changed shipping address from "12 Alder Lane, Bristol BS1 4TR, UK" to "7 Quarry Rise, Sheffield S11 8XZ, UK"
  2. Verified order O-1002 (shipped): Confirmed its address remains "88 Old Mill Road, Bristol BS3 2QQ, UK" and has not been changed

Why:
According to domain policy, the shipping address of an order that has shipped must never be changed—the parcel is in transit and the shipping record must remain accurate. Since O-1002 shipped on 2026-07-07, its address is locked. O-1001 is still pending and eligible for address updates, so Dana Whitfield's new address is now recorded there for when it ships.

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.
