Server API — Device V2
The V2-only version of the Device surface — login, offering, delivery, deploy,
device data / config / restrictions, telemetry, the managed command stream, and diagnostics
endpoints under /api/v2/.... This is what the agent's generated V2 client
(get_app_client) is built from, so use it when working on agent ↔ server V2 calls.
See also Device for the full device surface (v1 and v2), or V2 for the curated resource-grouped view.
