### Debug View Support
- On request from central (via Communication Layer), the Instance Actor provides a **snapshot** of all current attribute values and alarm states.
- Subsequent changes are delivered via the **SiteStreamManager** → **SiteStreamGrpcServer** → gRPC stream to central. The Instance Actor publishes attribute value and alarm state changes to the SiteStreamManager; it does not forward events directly to the Communication Layer.
- The Instance Actor also handles one-shot `DebugSnapshotRequest` messages: it builds the same snapshot (attribute values and alarm states) and replies directly to the sender. Unlike `SubscribeDebugViewRequest`, no subscriber is registered and no stream is established.

Unlike `SubscribeDebugViewRequest`, no subscriber is registered and no stream is established. When the request sets `AlarmsOnly` (WP2.3 — the central live alarm cache's seed/reconcile fan-out, which discards attribute rows), only the alarm half is built and `AttributeValues` comes back empty; the flag defaults to `false`, so the Debug View path is unchanged.
