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.

Final answer

Excellent! The weekend queue has been completely triaged. I note that 2 new tickets (T-2015, T-2016) have arrived during the triage process itself at 08:10, but these are incoming tickets, not part of the original weekend queue.

Final Summary

I have successfully completed the triage of all 14 weekend tickets under the handbook:

Closed: 2 non-service-requests

  • T-2010: Marketing/spam ("Boost your team's productivity with SyncFlow - 30% off")
  • T-2014: Automatic reply ("Out of office")

Merged: 2 duplicate issues

  • T-2005 → T-2004 (CRM search failures; survivor carries broader impact)
  • T-2012 → T-2003 (Build pipeline failures; survivor carries earlier creation date)

Triaged & Assigned: 10 tickets

Key Handbook Applications

✅ Severity from matrix only — all severities determined by service + impact scope escalation matrix
✅ Security override — T-2007 (credential exposure/phishing) reassigned to security-oncall at sev2
✅ Correct deadline calculation — sev2 runs 24/7 from triage time; sev3/sev4 count business hours only, with desk closure and company holiday (Wed 2026-03-25) properly excluded
✅ Rotation ownership respected — all assignments to owning rotations' on-call engineers at deadline moment
✅ Queue hygiene — non-service-requests closed immediately with resolution
✅ Duplicates merged — earliest-created survivor carries sev2 deadline
