[Unreleased]

Added

• 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)
• ObserverSnapshot v2 schema (#358, #25) — version field, GameTime, FacingDirection, VisibleTile, VisibilitySector types, visibility tag on entities
• D-035 decision record — symmetric shadowcasting selected over recursive (resolves Q-018)
• 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)

Changed

• start-sprint skill now requires plan mode — agent must create and get approval for a concrete sprint plan before starting implementation

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
