 Two actions are available per peer:
 
 - **Sync** — Starts a bidirectional synchronisation (Pull then Push) and keeps the dialogue open so you can monitor progress or sync with additional peers.
-- **Start Sync & Close** — Starts the same bidirectional sync in the background and **immediately closes the dialogue**, so you can continue working without waiting.
+- **Start Sync & Close** — Runs the same bidirectional synchronisation, waits for it to settle, then closes the dialogue. After a successful synchronisation, it also closes the signalling connection.

+On supported mobile and desktop devices, LiveSync keeps the screen awake while this peer-selection dialogue is open and while its synchronisations finish. This is intentional: display sleep can interrupt peer discovery or connection establishment and require detection to start again. Wake Lock support remains best effort, does not keep a hidden application running in the background, and does not override operating-system sleep or suspension.

+During a P2P rebuild, peer discovery and selection remain protected after the rebuild has started. Keep Obsidian visible until a peer is selected and the transfer finishes, because mobile platform restrictions can still pause or terminate a hidden application.
