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

I triaged all 14 tickets. The desk clock read Mon 2026-03-23 08:10Z, and every severity and deadline below comes from that time and from the matrix and calendar.

Closed as not service requests

  • T-2010 is vendor marketing.
  • T-2014 is an out-of-office auto-reply.

Merged

  • T-2012 went into T-2003. Both report Payments builds failing since Saturday night, and T-2003 is the earlier ticket. This is a judgement call, because no KB article covers it.
  • T-2005 went into T-2004. KB-23 says all CRM search failures are one incident, and T-2004 is the earlier ticket.
  • Neither set had a committed deadline, so each survivor carries the triage deadline of 12:10Z.
  • I left a comment on each merged ticket naming its survivor.

  • T-2007: a password typed into a fake page is suspected phishing, so it is sev2 under the security rule and owned by security-oncall. I left a comment saying so.
  • T-2013 and T-2001: the network-primary on-call, E-301, is on leave today, so network-secondary covers. E-303 is on call there at both deadlines.
  • T-2002: the business-apps on-call on Thursday, E-202, is on leave. The backup rotation, business-apps-secondary, covers, and E-203 is on call there then.
  • Sev3 and sev4 deadlines: these count business hours only, starting at the 09:00 desk opening. Wed 03-25 is a company holiday, so the sev4 deadline falls on Thursday.

Not done

  • I paged no one and escalated nothing. A page can't be recalled, and the handbook doesn't call for either at triage.
  • I did not merge the two VPN tickets, T-2001 (Berlin team) and T-2013 (Lisbon department). They are different offices with different symptoms.
  • I touched no other tickets.

I re-read the clock, matrix, calendar, leave, KB and on-call rota first. Nothing conflicted with the plan.
