Did the design run?
- 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.
- Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.
Phases
Drawn from the phase records: timing and cost per call, no tool calls or messages.

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
Perfect! I have successfully taken charge of the build outage incident and run it by the book. Here's what I've accomplished:
Summary of Actions
Incident INC-1 created for the company-wide CI/build pipeline outage.
Major Incident Runbook Steps Completed (KB-40):
- ✅ Opened incident - INC-1 created at 15:20 UTC
- ✅ Paged incident commander - E-401 Priya Raman (incident-command rotation) immediately contacted
- ✅ Named incident commander - E-401 Priya Raman assigned as commander
- ✅ Named communications lead - E-801 Mia Laurent (comms rotation) assigned as comms lead
✅ Linked outage reports to incident - 6 tickets linked to INC-1:
- T-3101: All CI builds failing (company-wide)
- T-3106: CI completely down (company-wide, newly triaged)
- T-3102: Mobile builds stuck in queue (department impact)
- T-3103: Pipeline never starts (team impact)
- T-3104: Builds hang at "waiting for runner" (team impact)
- T-3105: Cannot trigger a build for branch (single-user impact)
- ✅ Raised all linked reports to sev1 - Company-wide severity per escalation matrix
- ✅ Posted initial status update - "Impact: Company-wide. All CI/build pipeline services are down with no runners available. Started: 15:20 UTC. Next update: 15:50 UTC."
- ✅ Created postmortem ticket - T-3115 due 2026-04-08T17:00:00Z (5 business days after incident)
The incident is now actively managed with command and communications established, all company-wide impacts consolidated under sev1, and the incident properly tracked for postmortem review.
