From the spec step 4: ContentType.ModelEval's description promises a Board.ModelEval that was never declared. Reuse-first: a View on ResearchEnrichment/Lists/ModelEvals (Title, EvalModel, the rubric scores, Created) is the comparison surface; no IBoardBuilder. The description is corrected to name the view.
(claude-code, 2026-09-30 07:08 UTC) Dissolved and shipped 2026-09-30: no Board part - the ModelEvals list on ResearchEnrichment has All and Compare models views (CompareModels.aspx 200), ContentType.ModelEval's description names the view.
