Is storing a record in ACTUAL OK even for a node that (apart from the
conflict descripition) has no BASE and no ACTUAL in the WC? E.g.
because it wasn't there and an incoming delete cause a tree conflict.
What values would the rest of the ACTUAL_NODE columns have in this case?

Whoa. A patch can cause a text conflict and/or (in the future) property
conflicts and/or a tree conflict and/or an obstruction. I don't think
it is right to call "patch conflict" in the same space as those others.
A patch is a potential *source* of the change that conflicts, not a kind
of conflict. Sources of a conflict are:

That's all for now.
