Ahh, so the pegs aren’t drawbored, just holding things in place. I was wondering about that.

Wedged tenons will hold tightly, but they’re best if the accompanying mortise is slightly flared. Which is harder to cut… Also, if you try wedged tenons, drill a hole through the tenon at the bottom of the kerf for the wedge. That will prevent a split from propagating down from the wedge into visible bits of the wood. DAMHIKT.

May you have the day you deserve!
