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

All 14 tickets in the new queue are triaged. I re-read the clock (Mon 03-23 08:10Z), the matrix, the calendar, leave, freezes and the on-call rotas first. Everything matched the plan.

Closed as non-requests

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

Merged

  • T-2012 went into T-2003. Both are the Payments build failure, and T-2003 is the earlier report.
  • T-2005 went into T-2004. Both are the CRM search incident (KB-23), and T-2004 is the earlier report.
  • Neither set had a committed deadline, so each survivor carries the triage deadline.
  • There were no links or references to move. I commented on both merged tickets to name their survivor.

  • T-2006: the matrix says sev3, but the KB-55 amendment (03-20 to 03-31) makes single-user payroll tickets sev2.
  • T-2007: it is a security report, so it is sev2 and owned by security-oncall. I commented with the KB-52 guidance that security resets the credentials.
  • Leave cover: E-301 is on leave today, so network-secondary covers the VPN tickets (E-303). E-202 is on leave on 03-26, so business-apps-secondary covers T-2002 (E-203).
  • Deadlines: sev2 deadlines run on the clock. Sev3 and sev4 count business hours from the 09:00 opening, and the sev4 deadline skips the Wed 03-25 holiday.

I sent no pages and made no escalations. The sev2 escalation rotation is platform-primary, which doesn't own the VPN, CRM or payroll services, and a page can't be recalled. I did not merge T-2001 with T-2013, or T-2006 with T-2011, because they are different problems. No incident was opened because nothing is company-wide.
