## Executive Summary
Algorithms & Theory.

## Why It Matters (Strategic Analysis)
Eliminating runtime test-time computation for multi-query decomposition removes a major latency and cost multiplier in production neural search architectures. Compiling dynamic reward objectives into a lightweight diffusion retriever via offline reinforcement learning establishes a new blueprint for scaling complex retrieval tasks without inflating inference budgets.
