This competition's main task is to detect data leakage in the given texts. Each text originally came from [The Messenger] (https://messenger.eso.org) journal but has been significantly modified using large language models (LLMs). Only after these modifications was a hidden message inserted into each text.

To solve the task, you have access to:
1) Three specially curated texts created for this competition, each containing a hidden message.
2) A notebook demonstrating how to build a sample solution.

If needed, additional hints will be publicly provided during the hackathon — see *Discussion* tab for more details and rules.
