Project: Answer Quality Scorer

Build a scorer that grades generated answers before release. This becomes the answer-evaluation brain for prompt, model, retriever, and corpus changes.

Production roadmap

Product Standard

This project is intentionally not a toy "score equals three booleans" script. It models the first version of an evaluator a production team could extend with LLM-as-judge, human review, and observability.

Rubric

Explain every score

Each answer returns passed checks, failed checks, severity, and the first action.

Risk

Gate by severity

High-risk unsupported or missed-refusal failures block release.

Trace

Debug releases

Output includes versions so teams know what changed.
