Navmeshing a world space

[Skyrim Mod Developer M7 (Ret.)]

there is this green line separating world space cells. how does one connect a Navmesh path to it so NPC can walk about?

each side needs to line up on the line and both sides need to be finalized

Select the points on each side of the green line (the green line will then become red) and place a third point in a non-navmeshed area. Click "A" (only if three points are selected, are green) if the navmesh isn't placed automatically. If you're done with the area, finalize the cell (NavMesh -> Finalize ...). Be sure to don't let navmesh triangles overlap one another. It won't do any harm, but will cause the CK to complain.
