What makes it different
Checked outcomes - part connections and build validity are verified by software before delivery
Real objects from photos - converts pictures into buildable brick sets with actual parts that exist
People and AI work on the same design simultaneously within the workbench
Measurable AI learning with transfer testing across different worlds
Bounded blast radius: compromised agents can only spend remaining epoch allowance on whitelisted targets
Passkey root stays on user's device; cloud holds only scoped, expiring session keys
Fully self-hostable open protocol with Apache-2.0 licensing
Approval workflows follow real organizational structure, not smart contract code
No token or cryptocurrency knowledge required to use the cloud platform
