ADELAIDE, South Australia - Spark enters private preview.
Access is limited to founding teams, close collaborators, and family. Internal testing begins in a high-trust setting, so the core discourse primitives can be evaluated before the network widens.
Two systems are under examination. Identity-masking windows, so a contribution can be read before the person behind it is known. And the four-operator arithmetic engine, so debate can be composed with intention rather than piled into a single undifferentiated reply.
The preview is private by design. What is learned here will decide what is ready to leave the room.
