Hope these pics help and hope the consensus is I worry too much. Again, this is a 7-1/2"x7-1/2" post that is about 16' high supporting part of a balcony and also supporting roof plate that includes top ends of two valley beams. Red oak radio frequency vacuum kiln dried. House standing < 6 months.

This long check goes to the heart on mortise side. Top check to the tenon is opening up in last few days about an inch to right of the long check. Pic shows 2x4 collar to support temp 2x4 railing. These are full res images so they're big files.
