Mythos Preview's Chain of Thought on AES Möbius Bridge

This document is a technical report detailing Mythos Preview's process in discovering the Möbius Bridge concept, which contributed to an enhanced cryptanalytic attack on 7 rounds of AES. It outlines the original discovery process, emphasizing the clarity of the thought process involved. The document includes a rewrite of the original transcript, capturing the actions taken by the agent, including thinking, coding, and executing programs, while summarizing the outputs observed. The report highlights the task of inventing a new family of block-cipher cryptanalysis against 6-round AES-128, emphasizing the need for a novel analytical lens. It describes the working method prescribed for the task, which includes selecting candidate objects, computing their behavior over rounds, and iterating based on observed structures. The document also notes the resources available for the task and the constraints imposed by the oracle interface used for experimentation.
