/**
 * `llm` protocol (optional, behind `evidence.judge.allowLlm`, default off): an
 * OpenAI-compatible chat-completions endpoint asked to grade (need, block) pairs
 * with the same `score.support` rubric as `systemone`, answering strict JSON:
 *
 *   {"grades": {"q0": 2, "q1": 0, ...}}
 *
 * Temperature 0; the answer is validated (JSON object, every grade an integer
 * level of the rubric) and anything else is treated as no answer, so a chatty or
 * malformed reply degrades to the rule grades instead of corrupting the pack.
 * Token usage comes from the response. Meant for reference and experiments: a
 * general model is slower and dearer per pair than a decision model.
 * @module web-search-pro/pipeline/judges/protocols/llm
