Far too weak passive?

No, you played this correctly.

I think this c/r is probably -EV, but somebody else should probably confirm that if true.

What are you afraid of on this river? Unless you have a read that CO is so passive he would never raise without the nuts there is a really good chance that you're ahead. Worse hands will still call or raise your 3-bet, so 3-bet it and hope to see it capped.
