"""
Stub for Automated Evaluation Pipeline.

In a full FAANG-level production setup, this script would run in your CI/CD pipeline
using a framework like RAGAS or TruLens to evaluate the agent responses against a
golden dataset of queries.

To implement:
1. Define a golden dataset of prompts and expected contexts/answers.
2. Run the graph locally.
3. Score responses on metrics: Context Precision, Faithfulness, Answer Relevance.
4. Assert scores > threshold (e.g., 0.85) to pass the build.
