+# Godot Networking — Quick Reference
+
+Last verified: 2026-02-12 | Engine: Godot 4.6
+
+## What Changed Since ~4.3 (LLM Cutoff)
+
+### 4.6 Changes
+- **Networking section in breaking changes**: See the official migration guide for
+  specifics at the 4.5→4.6 level
+
+### 4.5 Changes
+- **No major networking API breaks** — core multiplayer API remains stable
+
+## Current API Patterns
+
+### High-Level Multiplayer
+```gdscript
+# Server
+func host_game(port: int = 9999) -> void:
+    var peer := ENetMultiplayerPeer.new()
+    peer.create_server(port)
+    multiplayer.multiplayer_peer = peer
+    multiplayer.peer_connected.connect(_on_peer_connected)
+    multiplayer.peer_disconnected.connect(_on_peer_disconnected)
+
+# Client
+func join_game(address: String, port: int = 9999) -> void:
+    var peer := ENetMultiplayerPeer.new()
+    peer.create_client(address, port)
+    multiplayer.multiplayer_peer = peer
+```
+
+### RPCs
+```gdscript
+# Server-authoritative pattern
+@rpc("any_peer", "call_local", "reliable")
+func request_action(action_data: Dictionary) -> void:
+    if not multiplayer.is_server():
+        return
+    # Validate on server, then broadcast
+    _execute_action.rpc(action_data)
+
+@rpc("authority", "call_local", "reliable")
+func _execute_action(action_data: Dictionary) -> void:
+    # All peers execute the validated action
+    pass
+```
+
+### MultiplayerSpawner and MultiplayerSynchronizer
+```gdscript
+# Use MultiplayerSpawner for automatic node replication
+# Use MultiplayerSynchronizer for property synchronization
+
+# MultiplayerSynchronizer setup:
+# 1. Add as child of the node to sync
+# 2. Configure replication properties in editor
+# 3. Set visibility filters for relevancy
+```
+
+### SceneMultiplayer Configuration
+```gdscript
+func _ready() -> void:
+    var scene_mp := multiplayer as SceneMultiplayer
+    scene_mp.auth_callback = _authenticate_peer
+    scene_mp.server_relay = false  # Direct peer connections
+
+func _authenticate_peer(id: int, data: PackedByteArray) -> void:
+    # Custom authentication logic
+    pass
+```
+
+## Common Mistakes
+- Not using `"any_peer"` for client-to-server RPCs (defaults to authority only)
+- Trusting client data without server-side validation
+- Using `"unreliable"` for game state changes (use for position updates only)
+- Not setting multiplayer authority (`set_multiplayer_authority()`) on spawned nodes
