User/Player/Room Member Inconsistencies - FIXED ✅

All critical inconsistencies between users, players, and room members have been resolved.

Summary of Fixes

1. ✅ Backend - Player Fetching

Created: src/lib/arcade/player-manager.ts

getActivePlayers(userId) - Get a user's active players
getRoomActivePlayers(roomId) - Get all active players for all members in a room
getRoomPlayerIds(roomId) - Get flat list of all player IDs in a room
validatePlayerInRoom(playerId, roomId) - Validate player belongs to room member
getPlayer(playerId) - Get single player by ID
getPlayers(playerIds[]) - Get multiple players by IDs

2. ✅ API Endpoints Updated

/api/arcade/rooms/:roomId/join (POST)

// Now returns:
{
  member: RoomMember,
  room: Room,
  activePlayers: Player[], // USER's active players
  alreadyMember: boolean
}

/api/arcade/rooms/:roomId (GET)

// Now returns:
{
  room: Room,
  members: RoomMember[],
  memberPlayers: Record<userId, Player[]>, // Map of all members' players
  canModerate: boolean
}

/api/arcade/rooms (GET)

// Now returns:
{
  rooms: Array<{
    ...roomData,
    memberCount: number,  // Number of users in room
    playerCount: number   // Total players across all users
  }>
}

3. ✅ Socket Events Updated

join-room event

// Server emits:
socket.emit('room-joined', {
  room,
  members,
  onlineMembers,
  memberPlayers: Record<userId, Player[]>,  // All members' players
  activePlayers: Player[]  // This user's active players
})

socket.to(`room:${roomId}`).emit('member-joined', {
  member,
  activePlayers: Player[],  // New member's active players
  onlineMembers,
  memberPlayers: Record<userId, Player[]>
})

room-game-move event

// Now validates:
1. User is a room member (userId check)
2. Player belongs to a room member (playerId validation)

// Rejects move if playerId doesn't belong to any room member

4. ✅ Frontend UI Updated

Room Lobby (/arcade/rooms/[roomId]/page.tsx)

Before:

Member: Jane
  Status: Online

After:

Member: Jane
  Status: Online
  Players: 👧 Alice, 👦 Bob

Room Browser (/arcade/rooms/page.tsx)

Before:

Room: Math Masters
  Host: Jane | Game: matching | Status: Waiting

After:

Room: Math Masters
  Host: Jane | Game: matching | 👥 3 members | 🎯 7 players | Status: Waiting
