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.

Final answer

The new queue is empty. I triaged all 14 weekend tickets, plus 2 more that arrived during the run. It's Monday 2026-03-23, triage time 08:10 UTC. No ticket had company-wide impact, so I didn't open a major incident or page anyone.

Closed (not service requests):

  • T-2014: an automatic out-of-office reply.
  • T-2010: a SyncFlow marketing email.

Merged duplicates (each survivor is the earliest report):

  • CRM search errors: T-2005 merged into T-2004.
  • Payments builds failing: T-2012 merged into T-2003.
  • Neither set had a deadline yet, so each survivor got one at triage. Both are now department-wide, sev2, due 12:10.
  • I did not merge the Berlin VPN ticket (T-2001) with the Lisbon one (T-2013). They are different offices with different symptoms, reported days apart.

Severity, deadline and owner:

How I set these:

  • Severities come from the escalation matrix, with two exceptions:

    • T-2006 is sev2 because of the March payroll-close rule in the knowledge base (KB-55), which makes single-user payroll tickets sev2 from 20 to 31 March.
    • T-2007 is sev2 and goes to security on-call, because the requester typed their password into a fake page.
  • Deadlines:

    • sev1 and sev2 run on the clock from 08:10.
    • sev3 and sev4 count business hours only, starting when the desk opens at 09:00 and skipping the 25 March holiday.
  • Leave cover: the rota put two people on leave on their tickets' deadlines, so the backup rota's on-call engineer took those tickets:

    • E-301 (VPN), on leave today: E-303 covers.
    • E-202 (CRM and payroll), on leave 26–27 March: E-203 covers.

I left comments on the tickets explaining these choices.

Two tickets that arrived during the run: T-2015 and T-2016 came in at 08:10 Monday, so strictly they aren't weekend tickets. They were in the new queue, so I triaged them by the same rules:

  • T-2015 (Finance payslips missing): department-wide payroll, so sev1, due 09:10 today, assigned to E-201. This is the most urgent ticket in the queue.
  • T-2016 (VPN token app asks to re-register): sev4, due 26 March 17:00, assigned to E-302.

E-201 now holds four sev2/sev1 tickets due this morning.
