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.

Phases

Decompose: 0.0s to 6.6s, finished, 0 tool calls, $0.022

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

T-1041 is triaged. It is now sev3, due 2026-03-17T17:20:00Z, and assigned to E-301 Yuki Sato. The worker checked the ticket after making the changes and confirmed all three.

  • Severity: sev3. The ticket is a VPN problem affecting a team: the Berlin sales floor, about nine people. The escalation matrix gives sev3 for that service and impact. The requester's seniority did not change the grade.
  • Deadline: 2026-03-17T17:20:00Z. The ticket had no deadline. It was triaged at 09:20:00Z that day, and the sev3 response target is 480 minutes, which gives 17:20.
  • Assignee: E-301 Yuki Sato. The network-primary rotation owns VPN. Yuki Sato is on call for it at the deadline, on a shift that runs 08:00–20:00Z.

The ticket's status also changed from new to open as part of triage. Nothing needed escalating, because the matrix names no escalation rotation for sev3. No other ticket was changed and no comment was added.

This is based on one worker's report. I had no tools to check it myself.

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.
