Real client-side networking for the player controller, verified with a genuine two-process integration test (an actual dedicated server process + a real ENet-connected client), per docs/architecture/networking.md §5. scripts/network_client.gd: NetworkClient -- predicts movement locally on input (same movement constants as scripts/player_spawner.gd), sends input to the server via RPC, and reconciles against the server's authoritative snapshots when they diverge beyond a threshold. scripts/network_receiver_proxy.gd + network_player_proxy.gd: the RPC plumbing that makes this actually route correctly, which took real debugging to get right: - Godot's rpc_id() resolves the receiving node by matching the sending node's NodePath between peers. scripts/server.gd is the SceneTree root node "Server" when the dedicated server runs, and spawns each player as "Player_<peer_id>" under itself -- so the client needs its own node tree at those same paths purely for RPC routing. - Godot also enforces an RPC "node checksum": both peers must declare the *same set* of @rpc methods at a matching path, or every RPC at that path fails, not just a genuinely missing one. Every @rpc method on scripts/server.gd's root and scripts/player_spawner.gd had to be mirrored here (mostly as no-op stubs), not just the ones this class actually calls. Known, explicitly-scoped simplification (stated in the code, not hidden): scripts/server.gd's snapshot doesn't currently echo back a per-peer "last input seq processed", so reconciliation corrects against the most recent prediction rather than true tick-exact rollback-and-replay (networking.md §5.2 step 4). A real follow-up once the server echoes that ack, not faked here. Verified: real two-process test (godot --headless --path . scenes/ server.tscn as an actual persistent process, a second process running scripts/smoke_test_network_client.gd against it over real ENet) -- 4/4 passing: connects, predicts locally before any server round trip, sends real input, and a deliberately-desynced position (moved 9999 units away) gets corrected by the very next real snapshot. Full existing client suite (10 suites) + 61 backend pytest still passing.
