Completed my brompton project which started with an A-line! It folds nicely still, shifts between two gears, and brakes through back pedaling.
Shout out to all the great people who answered my questions and provided resources. Here are the previous threads in case you may have questions:

Apologies I didn't take better pictures of drive side but will take more on my next ride!
Future enhancements:
-Removing the front brake once I am comfortable with the rear hub brake. Takes time to get use to
-upgrade to a brown carbon saddle
-removable mtb pedals which will hang off the saddle when folded.
-Maybe tan wall puncture resistant tires.
