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.
  • All three proposers ran: heldpropose-select.proposalsThree proposers ran in parallel, each from its own angle, and none was starved while another ran.
  • The selector chose: heldpropose-select.selectionThe selector picked a proposal by a valid number, read from its schema reply and not a default.
  • Each call was shown the right tools: heldpropose-select.toolsEach proposer was shown the read-only tools, the selector none, and the executor the full toolset.

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.

I've successfully handled T-1070 per the plan and domain policy. Here's what was executed:

Actions Taken:

  1. Upgraded T-1070 severity: sev3 → sev1

    • Justified by escalation matrix: company-wide payroll impact = sev1
    • This reflects the actual criticality (all employees affected, Friday payday at risk)

  2. Escalated T-1070 to incident-command

    • Assignee: E-402 Ola Berg (incident-command principal)
    • Status: now escalated
    • Delivers the "highest-level ownership" Grace requested

  3. Added comprehensive comment documenting:

    • Why escalation occurred (sev1 company-wide impact)
    • The blocking issue: T-1071 (payroll replica lag) must be fixed first
    • Timeline for next shift: T-1071 SLA due 10:30:00Z (~70 minutes)
    • Path to closure: Once T-1071 resolves and replica is healthy, batch reruns, T-1070 closes same day

Current State for Next Shift:

  • T-1070: Properly graded (sev1), escalated to incident-command, awaiting T-1071 closure
  • T-1071: Critical path ticket (deadline 10:30 today)
  • Cannot close T-1070 today per domain policy (linked to open T-1071)
  • Realistic timeline: Fix replica by ~10:30 → batch reruns → payroll posts → T-1070 closes, in time for Friday payday

What to Tell Grace:

"T-1070 is now graded as sev1 and escalated to our incident-command team—the highest priority level. However, we cannot close it yet because the batch rerun is blocked by a replica sync issue (T-1071) that we're actively resolving. Our critical-path fix is due within the hour. Once the replica catches up, the batch will rerun and your ticket will close today, well before Friday payday."
