Module judge 

LLM-as-judge — the shared async evaluation primitive behind the LLM-backed G:: guards and E:: criteria.

Mirrors ADK Python’s final_response_match_v2 / safety-evaluator approach: a judge model is prompted to render a structured verdict, and the verdict label is parsed back out of the model’s reply (robust to surrounding prose).

Structs

LlmJudge

A configured LLM-as-judge. Cheap to clone (Arc inside).

Verdict

The judge’s verdict.

Functions

parse_verdict

Parse a verdict from the judge model’s reply. Tolerant of extra prose around the JSON: it scans for the violation field’s boolean and the reason string, falling back to common labels (invalid, unsafe).

render_contents

Render conversation history into a plain-text block for a judge prompt, keeping role labels so the judge can reason about grounding.
