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

I triaged T-1041 and didn't touch any other ticket.

  • Severity: I set it to sev3. The matrix gives VPN with team-wide impact as sev3, and the ticket says about nine people on the Berlin sales team are affected.
  • Deadline: I set it to 2026-03-17T17:20:00Z. That is the triage time (09:20Z) plus the 480-minute response target for sev3. The ticket had no deadline before.
  • Assignee: I assigned it to E-301 Yuki Sato, and the ticket is now open. VPN belongs to the network-primary rotation, and Yuki is the engineer on call for that rotation at 17:20Z, when the deadline falls. Her shift runs 08:00Z to 20:00Z.

I didn't escalate it, because sev3 has no escalation rotation in the matrix.

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.
