The work is part of the product.
4789 publishes the maps behind the interface: what the person does, how the system responds, where the code lives, and how compatible services connect.
Workflows
Switch between the user journey and system flow, then open each path from discovery through playback.
3D architectureCodebase atlas
Explore subsystems, dependencies, failure modes, and the code gravity of the iOS implementation.
Engineering viewBlueprint
Read the technical composition without the marketing layer: products, services, contracts, and runtime boundaries.
Open JSON APIAdd-on protocol
Build a compatible catalog, metadata, stream, or subtitle service with a manifest and predictable endpoints.
Trust needs more than a polished hero.
The public product story stays simple. The implementation stays inspectable. Both are necessary for a system that connects private libraries, local devices, and third-party services.
Follow one evening through the whole stack.
Start with the workflow map, then descend into the atlas only when you want the code behind each transition.
