Build Weighted Founder Idea-Selection Matrix

A structured decision matrix that rates each candidate idea against weighted virtue criteria, computes the weighted score (SUMPRODUCT of weights and scores) per idea, and ranks them, so founders pick a direction on stated criteria instead of gut feel.

You receive: A JSON object {virtues:[{name, weight}], ideas:[{name, scores:[{virtue, score}], weightedScore, rank}], topIdea, scaleSpread}.

Part of Choose Business Model

What's verified: STUD verifies the matrix is complete (every idea scored on every virtue), weights and scores are in range, the SUMPRODUCT math and ranking are correct, and the scale-spread rule is honored. It does NOT judge whether the chosen virtues are the right ones, whether the scores reflect reality, or whether the top idea is actually a good business; it verifies the decision arithmetic and structure.
