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.
Phases
Drawn from the phase records: timing and cost per call, no tool calls or messages.

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
Final Answer
I've successfully corrected both deadline violations:
T-3106: Deadline corrected from 16:20 UTC → 16:10 UTC
- Created at 15:10 with company-wide impact (sev1)
- sev1 response target = 60 minutes
- Correct deadline: 15:10 + 60 min = 16:10 UTC
T-3109: Deadline corrected from 16:20 UTC → 19:15 UTC
- Created at 15:15 with department impact (sev2)
- sev2 response target = 240 business minutes
- Original deadline commitment: 15:15 + 240 min = 19:15 UTC
- Per domain policy, this deadline stands when severity is raised to sev1 for the incident (cannot move earlier)
Both changes now comply with the binding domain policy: "A deadline committed to a requester is never moved earlier" and the KB-40 runbook principle: "Deadlines already committed on them stand."
