 # IMPORTANT: This should be run on a NEW/EMPTY Supabase project
+#
+# KNOWN LIMITATIONS:
+# - auth.users data cannot be restored (Supabase managed schema)
+# - Tables with FK to auth.users may have partial data restoration
+# - Users will need to re-register or be imported via Supabase Admin API
+# - Some permission errors are expected and filtered out
+#
+# WHAT GETS RESTORED:
+# ✅ Complete database schema (all tables, indexes, constraints)
+# ✅ All RLS policies
+# ✅ All custom functions and triggers
+# ✅ Data in tables without auth.users dependencies
+# ⚠️  Partial data in user-dependent tables
+#
+# For more information, see backup_with_auth_export.sh
