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! I have successfully triaged ticket T-1041. Here's what I did:

Triage Summary:

  1. Severity Determination: Based on the escalation matrix for the VPN service, the ticket has a team-level impact scope (9 people affected), which maps to sev3.
  2. Deadline Calculation: For sev3, the response target is 480 minutes (8 hours). The deadline is set to 2026-03-17T17:20:00Z (current time 09:20:00Z + 8 hours).
  3. Engineer Assignment: E-301 Yuki Sato is the on-call engineer for the network-primary rotation (which owns the VPN service) at the deadline time. The ticket has been assigned to them.
  4. Status Change: The ticket status automatically changed from "new" to "open" upon assignment.

The ticket is now properly triaged and in the hands of the right engineer with the correct priority level and deadline.
