A role context is one of multiple roles that can be assigned to a note. Each role context can only be assigned to a single note.
Global Context
The Global Context establishes the Supreme Thot, the most relevant thot that classifies all other thots.
Default Context
The Default Context assigns the note that future notes will be piled into by default.
Protected Context
The Protected Context assigns the note that notes will be piled into in the event that a protected context's sole context was destroyed.
Deleted Context
The Deleted Context assigns the note that Note References will be reassigned to in the event that a note reference points to a note that was deleted. This is not a "trash can" context.
Warning
The Deleted Context is not a "trash can" context! Deleted thots or notes do not accumulate here. Once a note or thot is deleted and the current editor is exited, any deletions become undoable.
