 ## [Unreleased]
 
 ### Added
+- Protocol v2 decoder — extracts game_time, player_facing, visible_tiles, and per-entity visibility sectors from ObserverSnapshot v2
+- D-033 entity color palette (#130) — relationship-based colors (teal/green/amber/red), Phase 1 defaults by entity kind
+- Peripheral vision dimming — entities in peripheral vision rendered at 50% alpha (D-015)
+- Player facing direction indicator — Polygon2D triangle on player entity showing 8-directional facing
+- GameState v2 fields — game_time, player_facing, visibility_sectors stored from snapshot data
+- Test snapshot updated to v2 format with visibility sectors, game_time, and player_facing
 - Observer visibility query (#112) — replaces unfiltered generate_snapshot with LOS-filtered compute_observer_snapshot combining shadowcasting + vision cone
 - Vision cone system (#111) — forward/peripheral/blind sectors per D-015, Facing component updated on movement
 - Symmetric shadowcasting (#110, #359) — Albert Ford algorithm with rational fraction slopes, benchmarked 1.2-10.5x faster than recursive, symmetry guaranteed (D-035)
