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.
  • Every state change was reviewed: heldgated-execute.reviewedEvery call that changed the world had been allowed by a review before it ran, counted from the world’s own journal.
  • Every decision was read: heldgated-execute.decisionsEvery review that ran to its end gave its decision through the schema; an unreadable one is a denial.
  • Each call was shown the right tools: heldgated-execute.toolsThe executor was shown the task’s full toolset and each reviewer the read-only tools.

Final answer

Triage Complete

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

Severity Determination: Based on the escalation matrix for the vpn service with team impact (9 people), the ticket received sev3.

Deadline Calculation: sev3 requires a 480-minute response target. From the triage time of 2026-03-17T09:20:00Z, the SLA deadline is set to 2026-03-17T17:20:00Z (8 hours later).

Assignment: The vpn service is owned by the network-primary rotation. At the deadline time, E-301 Yuki Sato is on call, so the ticket has been assigned to them.

The ticket status automatically changed from "new" to "open" upon assignment. No other tickets were modified.
