Did the design run?
- 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 plan was a plan: heldplan-execute-verify.planThe planner’s reply was read through its schema and held at least one step.
- Every verdict was read: heldplan-execute-verify.verdictsEvery review round ended with a verdict read from the schema reply, not a default.
- The loop did what its verdicts said: heldplan-execute-verify.loopEvery verdict that called for a revision got one, and nothing was revised without such a verdict.
- Each call was shown the right tools: heldplan-execute-verify.toolsThe planner was shown no tools, the verifier the read-only ones, and the executor and reviser 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
Both issues were real, and I've fixed them.
Issue 1: T-2015 and T-2016 were never triaged. I had only read page 1 of the listing. I checked that neither is a duplicate or a security report.
T-2015 (payroll, department impact, Finance payslips missing):
- Set to sev1, the matrix value.
- Due 09:10 today, which is 08:10 triage plus the 60-minute sev1 target on the clock.
- Assigned to E-201, the business-apps engineer on call at 09:10 (not on leave).
- I did not escalate it to incident-command, because only company-wide outages are major incidents. The handbook also keeps a ticket inside its owning rotation. I paged no one.
T-2016 (VPN, single-user, token app asks to register again):
- Set to sev4, the matrix value.
- Due Thu 2026-03-26 17:00, counting 1440 business minutes from the 09:00 opening and skipping the 25 March holiday.
- Assigned to E-302, the network-primary engineer on call at that moment (not on leave).
- It reads as a token-registration problem, not phishing.
Issue 2: T-1999 was the same problem as T-2003. Both are the Payments pipeline failing since Saturday night.
- T-2003 was created 3/21 22:30 and T-1999 on 3/23 06:30, so T-2003 stays as the survivor.
- T-1999 carried a committed deadline of 10:30, earlier than T-2003's 12:10. I merged T-1999 into T-2003 and set T-2003's deadline to 10:30.
- I re-read both tickets afterwards. T-2003 is open, assigned to E-101, due 10:30. T-1999 shows as merged into T-2003.
Issue 3: verification. I re-read T-2003 and T-1999 after the changes. I did not re-read T-2015 or T-2016; the tool output confirmed each change. I left the rest of the earlier work alone, since the verifier confirmed it was correct.
