C[Black plays a standard Joseki, but this gives White the required connection to the K-edge. 

We later discussed whether i8 or perhaps h8 could have foiled this.

Indeed, there is no template for White; for example, Black j4 could have prevented g6 from connecting. But it could not have simultaneously prevented h9 from connecting and running toward the A-edge.]
