How it fits
A device is one place where interaction happens. The design aims to preserve the relationship with Sven as that surface changes, instead of making each interface a new identity owner.
Phaneum
Phaneum names a human-facing continuity role in the documented Sven architecture. It concerns how someone encounters and works with the continuing system through changing devices and interfaces.
Responsibility
An interface presents a permitted view of system state. It does not become the owner of identity, meaning or authority simply because a person interacts through it.
Information in
Appropriate user context and permitted views of the system’s work.
Information out
Interaction surfaces that express the relevant continuity and state.
This is a documented architectural role. It does not establish a public cross-device application or supported operating-system release.
