Unlike a typical elevated deck, that overhang does not look susceptible to sideways shifting so bracing is not likely needed for that purpose.
It’s wrong. No cantilever, undersized post, improper footing. Defer to an SE.
Hope this helps;
How did you determine it is not cantilevered?
You did. See post # 6. “Porch nailed to ledger”. That, in itself, is bad enough as you have to bolt to ledgers. And if there is a ledger, it can’t be cantilevered.
