The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experimental results on DetectRL-X reveal the strengths and limitations of current state-of-the-art detectors when applied to diverse linguistic resources.

C2weakest assumption

The chosen 8 languages, 6 domains, 4 commercial LLMs, and specific paraphrasing/perturbation attacks sufficiently represent authentic multilingual real-world LLM usage patterns and modifications.

C3one line summary

DetectRL-X is a multilingual benchmark for LLM-generated text detection that covers 8 languages, 6 misuse-prone domains, 4 commercial LLMs, and human-like editing operations plus attack strategies.
