Round 1 completed with the Glossary updated. Next I will go through the JSG to ensure we are in sync with this final naming decision and adjust were needed or unclear.

To clarify, we decided that there are only 4 types of nodes above and a Junction is either just a Junction or possibly a Junction Point, but it is not a Junction Node.

I will be going through the Wiki pages to update these references as required.

First, no need to say what geometry nodes used to look like. The reader gets no benefit.

I would say that an end node is special. When it is unattached and unterminated it acts like a geometry node. A dead end node is not a junction. So I would have three separate definitions for geometry node, end node and dead end node, and have "node" - > all three. That makes everything else you said easy.

"By this it appears how necessary it is for any man that aspires
to true knowledge, to examine the definitions of former authors;
and either to correct them, where they are negligently set down,
or to make them himself. For the errors of definitions multiply
themselves according as the reckoning proceeds, and lead men into
absurdities, which at least they see, but cannot avoid, without
reckoning anew from the beginning."

A road is a series of connected (or concatenated) segments that have the same essential attributes.

(The essential attributes that are the same are defined elsewhere.)
