MA-RAG + Evidence-Discussion Routing (EDR): Code, Results, and Reasoning Traces

This repository provides the code, experimental results, and reasoning traces for Evidence-Discussion Routing (EDR), an inference-time routing method for collaborative medical question answering. Integrated with MA-RAG, EDR uses option-probability signals to adaptively allocate agents between evidence-based independent reasoning and history-conditioned discussion, preserving independent judgments during collaboration.
The package includes evaluations on MedXpertQA and MedBullets, Qwen and Gemma model results, a gated fixed-allocation ablation, and additional seeded Gemma runs. Released artifacts include question-level predictions, complete generated answers for each retained reasoning round, routing probabilities and branch allocations, retrieval queries and document metadata, model configurations, integration instructions, and analysis scripts.
