As we're implementing this on the cli side, it's helpful to have a
clear consensus on what the workflow should be.

Currently we're thinking each update to a doc (e.g. using `rad edit`)
would be pushed to a seed (as an incomplete state), next person would
pull that doc and sign it (or discard it) until the quorum is reached,
in which case everyone would pull the final version.

Any comments on this?
