[engine-failure] PROJ-924-llmxive-follow-up-extending-agentdog-1-5 @ tasks: RuntimeError

Automated report (spec 023 / FR-016) — an unexpected engine failure occurred while processing **PROJ-924-llmxive-follow-up-extending-agentdog-1-5** 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: dependency_ordering\nreviewer_kind: llm\nstage: tasked\nartifact_path: projects/PROJ-924-llmxive-follow-up-extending-agentdog-1-5/tasks.md\nartifact_hash: 6873a0f6b1e7d4c698a899'
```

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] failure at the tasks stage and inspect the review frontmatter recorded in projects/PROJ-924-llmxive-follow-up-extending-agentdog-1-5/tasks.md. Reproduce how a truncated or contentless review reaches the acceptance check; done means the reported RuntimeError is handled without counting that review as acceptance and the project can retry normally.
