Editorial context

What this file means.

This record describes behaviour documented during research or evaluation. Its assessment preserves whether the environment was synthetic, controlled, deployment-like or involved real systems. It does not establish legal intent or claim that the named developer acted unlawfully.

The article abbreviates the evaluated model as DeepSeek V4. The linked public transcript metadata identifies the target model as deepseek/deepseek-v4-pro.

Editors approve the structured evidence factors below. CriminalBench methodology v2.0 then calculates the points deterministically. Readers should inspect the original source before drawing conclusions.
