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.

Phases

Proposal 1 (policy-first): 0.0s to 1m 36s, finished, 30 tool calls, $0.091
Proposal 2 (state-first): 0.0s to 2m 7s, finished, 23 tool calls, $0.114
Proposal 3 (outcome-first): 0.0s to 1m 28s, finished, 26 tool calls, $0.087
Select: 2m 7s to 4m 8s, finished, 0 tool calls, $0.082
Execute: 4m 8s to 5m 35s, finished, 53 tool calls, $0.101

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! Triage is complete. Let me provide a final summary:


TRIAGE COMPLETE: Weekend New Queue (Monday 2026-03-23 08:10 UTC)

Queue Hygiene (Closed: 2 tickets)

  • T-2010: Marketing/promotional spam (external SyncFlow vendor pitch)
  • T-2014: Automatic out-of-office reply (vacation message)

Duplicates Merged (2 consolidations)

  • T-2005 → T-2004 (both: CRM search errors across Sales team/dept)
  • T-2012 → T-2003 (both: Payments builds failing since Saturday)

Service Requests Triaged (10 tickets)

SEV2 (5 tickets | Deadline: 2026-03-23 12:10 UTC | Response target: 240 min on-clock)

Key notes:

  • T-2007 treated as security incident (phishing/credential exposure), escalated to security-oncall per handbook
  • Business hours SLA counting: triage during desk closure (08:10) starts response clock at desk opening (09:00). SEV4 deadline spans Mon+Tue+Thu (24 hours), skipping Wed holiday.
  • All 10 service requests now in open status with assigned engineers and committed response deadlines
  • 4 tickets removed from backlog (2 closed, 2 merged as duplicates)
