Not good, needs hardware!

This connection is not enough to hold 200 lb load. As a matter of fact it’s pretty bad.
It has hardware. The top image (which is not a great method but still better than Figure 2) has lags into joist end grain.
The bottom of the first image has posts through-bolted into the sides of joists, the strongest method.
The figure 2 drawing, showing posts bolted to the fascia, is dependent on the nails holding fascia to joists. Thermal and moisture cycling always loosens this connection and the guard becomes very weak in just a few years.
Which connection?
The bottom method shown IS figure 2. from the “Structure Magazine” article. By their testing the ". . . average failure load was only 47% of the test load requirement for a code conforming design." That is less than 100lbs.
The article clearly indicates the hardware needed to strengthen this connection (figure 3.)
The attachment illustrated by the OPS drawings is inadequate!
