Engineering Demos 

- Multiplayer: Paul demoed a collaboration workflow, whereby users can alert other people working in the same workspace that they are about to apply the modeled changes to real resources in the cloud, with a light-touch approval process for users to indicate a thumbs up / thumbs down before changes are applied. .

- Engine layer swap: Nick showed improvements in schema variant creation using the new hypergraph underpinning System Initiative, emphasizing ease of use, performance enhancements, and the integration of new functionalities like default prototype creation and efficient prop management.

- Workspace isolation: Scott and John demoed the Firecracker execution environment, focusing on the implementation of external and internal networking routes, user code execution through a virtual socket (VSOC), and the system's robustness against malicious code. 

- User Interface: Theo presented an updated user interface for the Attributes Panel, where users configure on the canvas. The new panel has a more streamlined and user-friendly design with nested values, sticky headers, and collapsible sections for better information management.
