I just reverse engineered the YellowKey BitLocker bypass
Microsoft shipped code that checks for a flag called "FailRelock" in every Windows 11 recovery image. When it's set to 1, after recovery unlocks your BitLocker drive, it never relocks it. All you need is a USB stick.
This code only exists in the recovery environment. Not in normal Windows. They left an entire debug testing framework in production.
