 ## [Unreleased]
 
 ### Added
+- End-to-end connection test (#81) — GDScript test spawning Rust server, connecting via LocalBridge, sending MoveNorth input, verifying player movement in snapshot response (D-030 Layer 3)
+- Batch input encoding (Vec\<PlayerInput\> wire format) — Protocol.encode_player_inputs() batches all inputs per tick into one framed message matching server expectations
+- EntityKind::Player fixture — snapshot_player.msgpack for cross-language testing, multi-entity fixture updated to include all 4 entity kinds
+- 7 new tests (4 batch encoding, 1 framed batch roundtrip, 1 Player fixture decode, 1 E2E connection), 43 total client tests passing
 - LocalBridge GDScript TCP transport (#79) — 4-byte big-endian length-prefix framing matching Rust server, StreamPeerTCP wrapper with partial read handling
 - ServerProcess subprocess manager — spawns/stops Rust server via OS.create_process(), auto-cleanup on destruction
 - SimBridge live transport integration — _process() polling loop for TCP receive/send, connection state machine (DISCONNECTED → CONNECTING → CONNECTED → ERROR)

 - Rejected alternatives R-004 through R-010 documented (pure Bevy, pure Godot, GDExtension, C++ GDExtension, Fyrox, custom framework, protobuf)
 
 ### Fixed
+- SimBridge wire format: inputs now batch-encoded as Vec\<PlayerInput\> array per server protocol (was sending individual inputs per frame)
+- SimBridge server args: positional address format ("127.0.0.1:9876") matching server CLI, port default corrected to 9876
 - Wire format mismatch: LocalBridge now uses rmp_serde::to_vec_named() (named maps) matching client Protocol.gd expectations
 - EOF on bridge read now returns BridgeError::Transport for disconnect detection instead of empty Vec
 - WalkabilityMap rewritten from flat Vec to chunk-based HashMap per D-012 architecture (Tyre review)
