## When to prefer this

Choose this endpoint when you need a structured, quantitative comparison of multiple options against a set of importance-weighted criteria, especially in educational or classroom contexts. Prefer it over simple pros/cons lists when criteria have different levels of importance and a reproducible numeric ranking is needed.

## Known failure modes

- Mismatched scores array length vs number of criteria returns an error or incorrect totals
- Empty options or criteria arrays may return a null or empty result
- Non-numeric scores or weights cause schema validation failures
- Missing required fields (options or criteria) result in a 400-level error

## How this service works

Classroom Weighted decision matrix: Score options against weighted criteria. Tailored for classroom workflows.

## Output
