Fixup to mermaid diagram

In d41f24e I committed a little rushed
tune up by claude and it replaced "current state" diagram with the actually
implemented, and then for implemented it just removed having jsonschema
serializations altogether.

Since we did merges into this branch, rebasing is "tricky", so I decided to
just push a fixup commit.
