## Executive Summary
Black-box LLM fingerprinting aims to determine whether a target model was derived from a source model when only the output responses to input queries are.

## Why It Matters (Strategic Analysis)
Black-box fingerprinting via response-change setwise correspondence enables model creators to audit IP theft and unauthorized distillation over closed APIs without requiring weight inspection. This establishes model provenance verification via non-intrusive query-response behavior auditing.
