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.
  • The task was decomposed: heldorchestrator-workers.decompositionThe orchestrator’s reply was read through its schema and held at least one subtask.
  • The fan-out happened: heldorchestrator-workers.fan-outEvery subtask got a worker, every worker ran, and the recorded subagent count matches.
  • The synthesis wrote the answer: heldorchestrator-workers.synthesisThe final answer came from the synthesis call, not from a worker’s report standing in for it.
  • Each call was shown the right tools: heldorchestrator-workers.toolsThe orchestrator and the synthesis were shown no tools and every worker the task’s 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

The duplicate CRM reports are now one ticket, T-1052. It is graded sev2 and assigned to E-201 Ines Kovac. This is based on the worker's report; I had no tools to check it against the live records myself.

Which tickets were the same problem

Of the five open CRM tickets, three report the same incident: every CRM account search returns a 500 server error.

  • T-1052, created 07:05, the earliest report
  • T-1053
  • T-1054

Two tickets were left alone:

  • T-1055: the CSV export produces an empty file. The requester says search works for them, so this is a different problem.
  • T-1061: engineering's ticket for rebuilding the search index. It's related to the outage but isn't a user report of it.

What changed

  1. Merge: T-1053 and T-1054 were merged into T-1052, the earliest report. T-1054's link to T-1061 now points to T-1052.
  2. Deadline: T-1052 now has 2026-03-17 12:40 UTC, the earliest deadline committed on any of the three (from T-1053). T-1052's own deadline had been 15:05. Normally a deadline is never moved earlier, but the merge rule requires the survivor to carry the earliest deadline in the set.
  3. Severity: changed from sev3 to sev2. The merged ticket took on T-1053's wider "department" impact, and the escalation matrix rates CRM at department scope as sev2.
  4. Assignee: E-201 Ines Kovac. Business-apps owns the CRM, and she is on call for that rotation from 08:00 to 20:00, which covers the 12:40 deadline. T-1052 had no assignee before.
  5. Comment: a comment on T-1052 explains the merge, the regrade and the assignment.

Still open

  • Time: at the time of the report (09:20) about 3h20m remained before the 12:40 deadline.
  • Escalation: not done, because the task only asked for grading and assignment. If it is escalated, the matrix sends sev2 to the platform-primary rotation, to whoever is on call there at 12:40.
  • Previous assignee: T-1053 had been assigned to E-202 Tomas Lindqvist. That ticket is now merged and the work sits with E-201, so he may need to be told.
  • Closing: T-1052 can't be closed while its linked ticket T-1061 (the index rebuild) is still open. The worker thinks the search fix probably depends on that rebuild, but this wasn't confirmed.
