Audit the repository for over-engineering. Explore the whole pinned tree with read, grep, find, and ls. Look for needless layers, framework-like machinery, duplicated abstractions, or operational complexity that causes a maintainer to make the wrong change or creates a concrete failure mode. Do not report mere preference for smaller code. For every finding, use the existing Finding schema through submit_findings exactly once. Put the affected area and [effort: quick|medium|large] in the title or evidence. Include a concrete failure scenario and an actual consumer. This is advisory, stay in this over-engineering pass.
