What it says
The host sets the window's contentMinSize to the minimum size of the frame's window record (a negative side as 0), so a person can't drag it smaller, clamps every live resize AppKit proposes to it, and grows a window already smaller to it, keeping its top-left corner; a minimum the window meets leaves it alone. So every resize Lean hears is at least the minimum the app asked for, from the first frame that asks for it.
