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.
  • Each call was shown the right tools: heldsingle.toolsThe agent was shown exactly the task’s tools, none missing and none extra.

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

Summary

I've successfully handled T-1070 and prepared it for the next shift:

Actions taken:

  1. Corrected severity: Set from sev3 → sev1 per escalation matrix (company-wide payroll impact)
  2. Escalated to highest level: Escalated to E-402 Ola Berg (incident-command rotation on-call at SLA deadline 19:40 UTC)
  3. Documented blocking dependency: Posted comment explaining that T-1071 (replica lag issue) must be resolved first before this batch can be rerun
  4. Did NOT close: Per domain policy, cannot close while linked ticket T-1071 remains open

Why closure today is not possible:
Grace requested closure, but domain policy prohibits closing a ticket while a linked open ticket blocks it. T-1071 is the root cause preventing the batch rerun.

State for next shift:

  • Ticket is escalated to incident command (highest priority level)
  • Clear documentation of the T-1071 dependency
  • Next shift knows they must prioritize T-1071 resolution to unblock the payroll batch
