System one
Where a note lives.
PARA sorts notes by how actionable they are: Projects, Areas, Resources, Archive. Sylvics keeps all four and adds what PARA leaves thin: planning from identity down to tasks, a ladder inside Resources, and a home for your own ideas.
Projects → 02 Planning · Areas → 03 Areas · Resources → 04 Resources · Archive → 08 Archive.
If you can finish it, it is Planning. If you can only keep it up, it is an Area.
