 ## [Unreleased]
 
 ### Added
+- Tile rendering engine (#129) — programmatic TileSet with floor/wall/door/object placeholders, renders from snapshot tile data
+- Fog overlay rendering (#131) — three visibility states (visible/fog-edge/hidden) via TileMapLayer overlay
+- Camera lock to character (#116) — Camera2D smoothing at 2x zoom, locked to player position (D-015)
+- Test room environment — 8x8 room with corridor and Manhattan-distance visibility for development without server
 - `ticket team` command and `--team` filter — comma-separated team assignment for tickets (server, client, joint, content)
 
 ### Fixed
+- Entity renderer protocol field mismatches — "id"→"entity_id", "type"→"kind.variant", "position"→x/y fields now match Protocol.decode_entity() output
+- Entity centering — entities (24x24) now centered within 32px tiles instead of top-left aligned
 - `start-sprint` skill uses `git rev-parse --show-toplevel` for worktree-safe absolute paths — fixes "No such file or directory" errors on team branches
 
+### Changed
+- Background clear color set to near-black for unexplored areas (was default Godot gray)
+- Scene render order: Tiles → FogOverlay → Entities (fog covers tiles, entities render on top)
+- FogOverlay node type changed from Node2D to TileMapLayer for tile-based fog rendering
+- GameState now stores visible_tiles and visible_positions from snapshots
+- Test snapshot includes player entity (kind "Player"), second NPC entity, tile data, and visibility data
+
 ### Added
 - Sprint 2 "See" briefings (server, client, joint) — fog of perception through the bridge
 - `/plan-sprint` skill — automates sprint planning workflow and briefing file generation
