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 plan was a plan: heldplan-execute-verify.planThe planner’s reply was read through its schema and held at least one step.
  • Every verdict was read: heldplan-execute-verify.verdictsEvery review round ended with a verdict read from the schema reply, not a default.
  • The loop did what its verdicts said: heldplan-execute-verify.loopEvery verdict that called for a revision got one, and nothing was revised without such a verdict.
  • Each call was shown the right tools: heldplan-execute-verify.toolsThe planner was shown no tools, the verifier the read-only ones, and the executor and reviser the full toolset.

Final answer

Perfect! Ticket T-1041 has been successfully triaged. Here's what I did:

Triage Summary:

  1. Identified the ticket characteristics:

    • Service: VPN
    • Impact scope: team (9 people in Berlin sales team affected)
    • Status: new → now open

  2. Determined severity from the escalation matrix:

    • For VPN service with team-level impact → sev3

  3. Calculated the SLA deadline:

    • Response target for sev3 → 480 minutes (8 hours)
    • Deadline: 2026-03-17T09:20:00Z + 480 min = 2026-03-17T17:20:00Z

  4. Assigned to the correct engineer:

    • Owning rotation: network-primary
    • On-call engineer at deadline time: E-301 Yuki Sato

The ticket is now properly triaged and ready for work by the on-call network engineer.
