Respectfully, I am not clear on what you want to achieve. Raised beds require a lot of work and resources, and full shade severely limits what can be grown. Can you tell us your goal? That would really be helpful.
It's mostly been a curiosity of mine. While I have full shade growing areas, my health situation means I probably won't act on any benefit. This knowledge might help others decide if they want raised beds in full shade, or avoid that extra work in those areas.
