## Executive Summary
StateBench: Testing how language models track state changes over long documents.

## Why It Matters (Strategic Analysis)
Transformer architectures face inherent theoretical limits when processing long dependency chains for complex state updates, making fine-grained benchmarks like StateBench necessary to differentiate the capacity of recurrent and hybrid memory systems. Evaluating models across distinct algebraic primitives provides architectural clarity beyond simple needle-in-a-haystack retrieval metrics.
