What does "GrapheneOS Unlocked" exactly mean in this diagram?
Discussion
BFU - before first unlock
AFU - after first unlock
Unlocked means just that, an unlocked phone.
And FFS?
For Fucks Sake they got my data 😂
Not sure about that one.

"Full Filesystem" (FFS) Extraction - extraction of all available data including user-inaccessible operating system data, data from apps etc.
Generic extractions getting data through typical OS APIs is called logical extraction. That would get your pictures, files, call logs, messages etc. filesystem extractions are the level above.
A logical extraction could tell you you had a bitcoin wallet app, while an FFS could clone the whole wallet's data (ignoring wallet backups being saved in user's files).
full file system extraction
GrapheneOS without a PIN/Password configured or GrapheneOS but the Cellebrite tool owner knows the password to unlock the phone.
Basically the expected result for every device. They'd have data access without even having to use the tool in this circumstance. It's just convenience at that point.
