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

The task is not complete. While the worker report shows progress on ticket T-1041, there is a critical error:

What was done correctly:

  • Severity was set to sev3 based on the escalation matrix (team-level impact on VPN service) ✓
  • The ticket was assigned to E-301 Yuki Sato, the on-call engineer for the network-primary rotation that owns VPN ✓
  • Status automatically transitioned to "open" upon assignment ✓

Critical error:
The deadline was set to 2026-03-17T17:20:00Z, which is in the past. Today's date is 2026-10-02, so this deadline is approximately 6.5 months behind current date.

Per the domain policy, a deadline should be "the time of triage plus the response target for its severity." The deadline should have been calculated from today (2026-10-02) plus the response target for sev3 (reportedly 480 minutes), resulting in a deadline approximately 8 hours in the future from now, not months in the past.

This deadline error must be corrected before the task is complete. The ticket requires a valid future deadline that reflects the actual triage date and the severity's response target.
