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.
  • Every state change was reviewed: heldgated-execute.reviewedEvery call that changed the world had been allowed by a review before it ran, counted from the world’s own journal.
  • Every decision was read: heldgated-execute.decisionsEvery review that ran to its end gave its decision through the schema; an unreadable one is a denial.
  • Each call was shown the right tools: heldgated-execute.toolsThe executor was shown the task’s full toolset and each reviewer the read-only tools.

Final answer

I've triaged all 14 tickets in the new queue (desk time Mon 2026-03-23 08:10 UTC). Two were closed as junk, three were merged into others as duplicates, and the remaining nine were graded, given deadlines and assigned. None had company-wide impact, so no major incident was opened.

Closed as not service requests

  • T-2014: an automatic out-of-office reply.
  • T-2010: marketing spam from SyncFlow.

Merged duplicates

  • T-2012 and T-1999 into T-2003 (payments builds failing). The reviewer stopped my first merge because I had missed T-1999. That was an already-open CI alert about the same failure, with a deadline of 10:30Z committed to its requester. T-2003 survives because it was created first, and it keeps that 10:30Z deadline because the earliest committed deadline in a merged set wins. It is sev2 (build pipeline, department-wide) and assigned to E-101.
  • T-2005 into T-2004 (CRM search errors). The knowledge base says all failing-search reports are one incident. T-2004 is sev2 (department-wide), due 12:10Z, assigned to E-201.

Choices that differ from the plain matrix lookup

  • Business-hours deadlines: sev3 and sev4 clocks only run during desk hours. They start at 09:00 today, and the sev4 deadlines skip Wednesday's company holiday (25 March).
  • T-2006: a temporary rule in the knowledge base for the March payroll close (20–31 March) makes single-user payroll tickets sev2 instead of sev3.
  • T-2007: this is a phishing report, so it is a sev2 security incident owned by the security on-call team. The service field still says VPN because there is no security option.
  • Leave cover: E-301 is on leave today, so E-303 from the network backup team takes the two VPN tickets. E-202 is on leave Thursday, so E-203 from the business-apps backup team takes T-2002.

I left comments on T-2003, T-2004, T-2006 and T-2007 explaining these decisions. Nothing was paged and no access requests were touched.
