home

The person's home folder, /zero/home/<username>: their own files, carried from world to world in the editor and stored in the account's home world.

local folder, why = home.folder()
if folder then
	vfs.write(folder .. "/notes.md", "carried into every world I open")
end
print(home.status().state)

local guid = home.get()          -- the account's home world, or nil when it has none
local ensured = home.ensure()    -- the same world, created the first time it is needed

guides { path: "core/home" } covers what the folder is for and the rule that keeps world content from depending on it.
