[engine-failure] PROJ-397-predicting-avian-foraging-behavior-from- @ tasks: RuntimeError

Automated report (spec 023 / FR-016) — an unexpected engine failure occurred while processing **PROJ-397-predicting-avian-foraging-behavior-from-** 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: fleshed_out_complete\nartifact_path: projects/PROJ-397-predicting-avian-foraging-behavior-from-/specs/001-predicting-avian-foraging-behavio'
```

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 locating the LLMReviewer ordering implementation that parses review frontmatter during the tasks stage, then reproduce the reported truncated YAML beginning with reviewer_name: ordering. Done means a contentless review cannot count as acceptance and the project remains schedulable for its normal retry cadence.
