Engineering Demos 

Workload isolation: John showed the Firecracker execution artifact lifecycle, walking through three areas: how software is compiled, how artifacts are stored in the artifact registry, and consumption of artifacts. 

UI Improvements: Theo demoed a number of improvements, including using icons to navigate to the correct tab in attributes panel, reflecting selected components in the URL, using middle-click to drag the canvas, pinch-to-zoom, showing a loading screen instead of flashing on empty state, and aesthetic tweaks to the interface. 

Reactivity in secret management and better socket connections: Victor showed work to ensure the proper re-execution of qualifications after a credential is changed. Then, he introduced 'connection annotations' in sockets, allowing more safety and correctness in socket connections.

More UI improvements: Wendy showed improvements including a new confirmation modal for deletion in change sets, support for multiple code items in the code panel for components, and adjustments in scroll speed to account for when a user is zoomed out. 

Engine layer swap: Nick demoed a diagram of the hypergraph underpinning their System Initiative, focusing on component and attribute values. He explained how their new engine simplifies data representation and management, improving the system's efficiency.
