The application layer is what people use. Wemazu deploys from Git, Rozuro does the books, Sumezi sends the newsletters. All three are live.
Under that sit Modular and Soriku. Modular handles content, permissions and routing. Soriku handles AI. Under Soriku comes Akyru, our own model. Under everything sits Simezu for accounts, sessions and payments.
Each product still ships on its own cycle. What they do not get is a private copy of the hard parts. That is the point of the ecosystem map on this site: show the dependencies instead of hiding them in a slide deck.
Outside that map sit MydayPrice, Simuze and the Kimezu whitelabel. Different rules, on purpose.
