Yes the first.

I was looking through English Historic Carpentry, Cecil Hewett, and found a few examples more looking like the second posting. Knowing the walls are concrete and the box outs, as well, helps the issue.

On page 219, fig 199 of said book, is an example I like. The arched braces are thicker and full pieces running from below the plate to the tie, really beefy. Kind of half crucks.
