Automated report (spec 023 / FR-016) — an unexpected engine failure occurred while processing **PROJ-059-automated-detection-of-algorithmic-bias-** at stage `plan`.

RuntimeError: LLMReviewer[methodology]: review frontmatter has neither `verdict:` nor `concerns:`/`action_items:` — a contentless/truncated review MUST NOT count as acceptance (false-convergence guard).

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[methodology] failure during the `plan` stage and inspect the review frontmatter for the planned artifact under `projects/PROJ-059-automated-detection-of-algorithmic-bias-/specs/001-automated-detection-of-algorithmic-bias/`. Reproduce the contentless or truncated review and verify that the normal retry recovers without treating it as acceptance.
