Engineering Demos 

- File injection: Scott demoed the ability to configure binaries such as SDF and Pinga from the command line with additional arguments allowing us to pass previously static things like certificates or credentials. This importantly includes the ability to have a secure certificate chain to Postgres/RDS.

- SI in Production on SI: John showed the first version of a working production stack, with four services - Web, SDF, Pinga and Council - all running in ECS, and Veritech executing functions on metal nodes. The setup also involves a CloudFront distribution, a load balancer, and managed NATS for messaging.

- Engine layer: Nick demoed connections between components in the new engine, including attribute values. He explained the shift from the concept of edges and connections to a simpler system where component connections create an attribute prototype argument.
