    I'm not exactly sure what "per the logic of the design" is supposed to
    mean, and I suspect that someone reading through the git logs would be
    just as lost. As far as I'm aware, any patch to OVS should be "per the
    logic of the design", right?

In general, a change can be consistent with an 
existing design or a change to the existing design itself. 
However, “per the logic of the design” can be assumed by default
and hence is usually considered superfluous, which I think is what you
want to convey – sure.

I’ll include the text I used on the related thread, as I agree, the
motivation is not necessarily obvious, just by linking ct_orig_tuple to
ct_state, as I did in this commit message.
    
    Do you mean "The ct_orig_tuple fields are designed to be read only if
    the ct_state is valid, so do not populate that field if the packet has
    not gone through the connection tracker"?

    I think that this kind of
    description would provide at least a little extra context to help
    understand the motivation behind the change.
