The neutral wire forms a part of the live circuit along with the hot wire. But the first rule is there are no rules. By convention the white wire is neutral the black wire is hot and a green or bare wire is ground. In breaker there is a shared bar with both ground and neutral wires connected.

You should not have a black ground wire or a white ground wire. Inside the can lights there is quick connectors that i cut and used wire nuts but i have rechecked this several times and everything seems correct.
