These are notes related to one specific project and are so stored in a single folder specific to that project. They don’t need to follow a single format like evergreens. In a way, they are like fleeting notes, only that they are kept in a specific folder in the context of a goal (connect a project with a goal).
After the project ends, these notes can either be deleted or processed into more useful permanent notes that can be used for future projects.
