"The only ones that matter are soil-borne ones with durable spores".
If they are soil borne then they are not likely to wind borne.

Usually.

If the leaves have spores on them then they would stay dormant till
spring/ summer.

Only if they are durable - not all are.

I have seen nothing to say where the spores enter the plant through the
root, or what.

I have. The evidence is that it is the leaves. However, it is not
yet fully understood.
