 Detection keeps moving, so a stealth engine is only as good as its last rebase. Fortress tracks the latest Chromium monthly, re-runs the full gauntlet, and ships a patch whenever a detector finds a new tell, so what you run keeps matching what a real Chrome install looks like. [Watch the releases](https://github.com/tiliondev/fortress/releases) to follow the `v2` MaskConfig work, or [star the repo](https://github.com/tiliondev/fortress/stargazers) if it's useful to you.
