TL;DR · WeSearch summary

The FRA Challenge 75746d-2025 involved two reports from Claude and Codex attempting to solve the same problem. While Claude focused on analyzing the footer image without recovering the flag, Codex successfully extracted the flag by enhancing low-contrast pixels in the image. Both reports adhered to the rule of not searching for external solutions and only worked with the provided assets.

Key facts

▪The challenge required solving only the first step and stopping afterward.
▪Claude did not recover the flag but identified the footer image as a potential artifact.
▪Codex successfully recovered the flag by enhancing the footer image, revealing flagga{alpha_mail}.
