Matching primary charge explains 99.2% of the NDCG@10 gap between BM25 and best systems on LeCaRDv2 because benchmark relevance is defined by charge-encoding elements.

An LLM agent self-evolves a set of query-rewriting rules that raise BM25 performance on the LeCaRD-v2 legal retrieval benchmark above human-designed and greedy baselines.
The paper identifies three pathologies of probabilistic RAG in legal retrieval (mereological blindness, diachronic blindness, causal opacity) and derives four deterministic architectural commitments to address the hierarchical, temporal, and institutional structure of legal knowledge.
