No eligible device or session won't start?

+-- Did you call Wearables.initialize(context)? -> Must happen before SDK usage
|
+-- Did registration complete? -> Observe Wearables.registrationState
|
+-- Is Developer Mode enabled? -> Enable it in the Meta AI app for dev builds
|
+-- Does Wearables.devices contain a linked device? -> Check Bluetooth and range
|
+-- Did createSession() or addStream() return a DatResult failure? -> Surface the typed error
Developer Mode must be enabled for local development builds that use APPLICATION_ID = 0.

Prefer logging typed DatResult failures and observed state transitions over generic exceptions.
