[engine-failure] PROJ-1034-llmxive-follow-up-extending-infinite-wor @ tasks: RuntimeError

Automated report (spec 023 / FR-016) — an unexpected engine failure occurred while processing **PROJ-1034-llmxive-follow-up-extending-infinite-wor** 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-1034-llmxive-follow-up-extending-infinite-wor/specs/001-llmxive-follow-up-extending-infinite-wor/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.

Start by tracing the LLMReviewer[ordering] handling for review frontmatter at the tasks stage, using spec 023 / FR-016 and the reported PROJ-1034 artifact path as entry points. Reproduce the RuntimeError and verify that a contentless or truncated review without verdict or concerns/action_items cannot count as acceptance while the project remains schedulable.
