[engine-failure] PROJ-369-evaluating-the-robustness-of-statistical @ tasks: RuntimeError

Automated report (spec 023 / FR-016) — an unexpected engine failure occurred while processing **PROJ-369-evaluating-the-robustness-of-statistical** at stage `tasks`.

```
RuntimeError: LLMReviewer[ordering]: review frontmatter has neither `verdict:` nor `concerns:`/`action_items:` — a contentless/truncated review MUST NOT count as acceptance (false-convergence guard). First 200 chars: '```yaml\n---\nreviewer_name: ordering\nreviewer_kind: llm\nstage: tasked\nartifact_path: projects/PROJ-369-evaluating-the-robustness-of-statistical/specs/001-evaluating-the-robustness-of-statistical/tasks.'
```

The project remains schedulable; it will retry on its normal cadence and recover once the underlying defect is fixed. Closing this issue does not require any project-state change.

Trace the LLMReviewer[ordering] handling for the PROJ-369 tasks artifact and inspect how its review frontmatter is parsed. Reproduce the RuntimeError with the shown truncated review, then verify that a review lacking verdict, concerns, or action_items cannot count as acceptance while the project remains schedulable.
