## Executive Summary
Speculative decoding (SD) speeds up large language model (LLM) serving, but its gain depends on the workload's \emph{shape}, such as batch size and context.

## Why It Matters (Strategic Analysis)
Static speculative decoding yields inconsistent latency gains because draft token acceptance rates degrade under fluctuating batch sizes and sequence lengths. Content-adaptive drafter routing optimizes token acceptance directly at the serving layer, significantly increasing compute efficiency for heterogeneous production workloads.
