Maybe a silly question, does the parking brake activate both shoes on each wheel or only the rear shoe?

I believe both.

deleted because foama below is right, the parking brake actuator braces off the auto-adjuster

The question is not silly at all.
Correct, the cable is attached to only one shoe, as with most other cars, but correct is also, both shoes are operational with a pulled handbrake.
How is that? The hinged lever attached to the cable presses the forward facing shoe onto the the drum. Initially this is also the case when the brake lever is is only pulled very lightly. When the forward-facing lining presses onto the drum, the brake-selfadjuster comes in. It is attached to the lever on the forward-facing side, and the other shoe on the other. With the pulled hand brake lever, it effectively distributes the force between both shoes, and both press on the drum.
With regular braking, the lever on the forward facing lining is not pulled by the brake cable. It rests on the shoe, between the shoe and the self-adjuster. The secondary cylinder pushes both shoes onto the drum when applying the foot brake. The self-adjuster limits the amount of retreat of the shoes after braking has stopped.
What foama said...

I never realized the self-adjuster is designed to take the force of stopping the car. does this mean that the failure of the self-adjuster will prevent the e-brake from working as it appears the e-brake lever pivots against the self adjuster? https://mirageforum.com/forum/attach...4&d=1518623817

Only during braking via the handbrake lever does the self-adjuster have any real force applied.
Otherwise, the self-adjuster is what the shoes rest on when there is no braking happening at the moment. The shoes "retreat" from the drum after braking and rest on the self-adjuster. The purpose of the self-adjuster is to take up too much slack , so the shoes don't have to move exessively for braking.
The best thing for understanding is to take a drum off and look for yourself.
