**TLDR:** Building production-grade LLM evaluation framework: test set design (sampling strategy, edge cases, adversarial), automated eval pipeline (pytest-like setup), LLM-as-a-judge strategies (GPT-4o vs Claude vs ensemble, bias detection), error analysis (clustering, root cause), A/B testing protocols (statistical significance, sample size). Objective comparison of 7 production artifacts from Modules 15-20. Clean evaluation code with Python + Pydantic.
