[engine-failure] PROJ-372-assessing-the-sensitivity-of-regression- @ tasks: RuntimeError

Automated report (spec 023 / FR-016) — an unexpected engine failure occurred while processing **PROJ-372-assessing-the-sensitivity-of-regression-** 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-372-assessing-the-sensitivity-of-regression-/specs/001-assessing-the-sensitivity-of-regression/tasks.m'
```

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 with the LLMReviewer[ordering] validation at the tasks stage and the generated review frontmatter for projects/PROJ-372-assessing-the-sensitivity-of-regression-/specs/001-assessing-the-sensitivity-of-regression/tasks.md. Reproduce spec 023 / FR-016 and trace why the review lacks verdict or concerns/action_items; done means malformed reviews cannot count as acceptance and the normal retry recovers.
