+-- Initial setup migration for LivingDexTracker
+-- This sets up any additional schema needed
+
+-- Note: RLS is already enabled on auth.users by default in Supabase
+-- and proper policies are already in place
+
+-- Create a profiles table if we need additional user data
+-- This is optional for the current setup since we only use Supabase for auth
+-- and store everything else in MongoDB
+
+-- CREATE TABLE profiles (
+--   id UUID PRIMARY KEY REFERENCES auth.users(id) ON DELETE CASCADE,
+--   username TEXT,
+--   avatar_url TEXT,
+--   created_at TIMESTAMPTZ DEFAULT NOW(),
+--   updated_at TIMESTAMPTZ DEFAULT NOW()
+-- );
+
+-- Enable RLS on profiles table
+-- ALTER TABLE profiles ENABLE ROW LEVEL SECURITY;
+
+-- Create RLS policies for profiles
+-- CREATE POLICY "Users can view own profile" 
+-- ON profiles 
+-- FOR SELECT 
+-- USING (auth.uid() = id);
+
+-- CREATE POLICY "Users can update own profile" 
+-- ON profiles 
+-- FOR UPDATE 
+-- USING (auth.uid() = id);
+
+-- Note: MongoDB collections (pokedexentries, catchrecords) are handled by the app
+-- Supabase is only used for authentication in this hybrid setup
