// The share a device's agent is granted is decided in internkim and reaches

// once on each side of a boundary neither can import across. config/
// runtime.example.json is the committed shape a device is deployed with, and
// internkim's renderer is held to the same file, so a field renamed on either
// side stops matching here and in internkim's conformance test rather than on a
// box.
