Read the proof. Catch the claim. Score the route.

What the Arena tests

DevodeRator rounds are built from finished public articles, books, and canon essays. The best answer is rarely a loose fact; it is the answer that follows the article's real argument. Look for the problem that made the work matter, the receipt or source trail that supports the claim, the limit that keeps the claim honest, and the next operator move the reader can take.

A clean run means you did more than skim. You caught where the system has proof, where private custody stays private, and where a public route points back into the larger 0S without pretending every workflow is automatic.
