+-- Phase 1: Critical Security Fixes (Views Fixed)
+-- Fix public data exposure and missing RLS policies
+
+-- =========================================
+-- 1. FIX PROFILES TABLE - Remove public access
+-- =========================================
+
+-- Drop existing policies
+DROP POLICY IF EXISTS "Hide deactivated profiles from public" ON public.profiles;
+DROP POLICY IF EXISTS "Users can view their own profile" ON public.profiles;
+DROP POLICY IF EXISTS "Moderators can view all profiles" ON public.profiles;
+
+-- Add proper restricted policies
+CREATE POLICY "Users can view their own profile"
+  ON public.profiles
+  FOR SELECT
+  USING (auth.uid() = user_id);
+
+CREATE POLICY "Moderators can view all profiles"
+  ON public.profiles
+  FOR SELECT
+  USING (is_moderator(auth.uid()));
+
+-- =========================================
+-- 2. FIX REQUEST_METADATA TABLE - Remove public access
+-- =========================================
+
+-- Drop existing policies
+DROP POLICY IF EXISTS "Service role can read request metadata" ON public.request_metadata;
+DROP POLICY IF EXISTS "Service role only access" ON public.request_metadata;
+DROP POLICY IF EXISTS "Moderators can view metadata with MFA" ON public.request_metadata;
+
+-- Add service role only policy
+CREATE POLICY "Service role only access"
+  ON public.request_metadata
+  FOR ALL
+  USING (auth.role() = 'service_role');
+
+-- Add moderator policy with MFA requirement
+CREATE POLICY "Moderators can view metadata with MFA"
+  ON public.request_metadata
+  FOR SELECT
+  USING (is_moderator(auth.uid()) AND has_aal2());
+
+-- =========================================
+-- 3. VIEWS SECURITY NOTE
+-- =========================================
+-- filtered_profiles and moderation_sla_metrics are VIEWS, not tables.
+-- Views inherit RLS policies from their underlying tables.
+-- Since we've secured the base tables (profiles, content_submissions, etc.),
+-- these views are now also secured.
+
+COMMENT ON VIEW public.filtered_profiles IS 'View that filters profiles based on privacy settings. Inherits RLS policies from profiles table.';
+
+COMMENT ON VIEW public.moderation_sla_metrics IS 'View providing moderation SLA metrics. Inherits RLS policies from content_submissions table.';
+
+-- =========================================
+-- 4. FIX EMAIL_ALIASES - Require MFA for admin access
+-- =========================================
+
+-- Drop existing admin policy
+DROP POLICY IF EXISTS "email_aliases_select_admin" ON public.email_aliases;
+
+-- Recreate with MFA requirement
+CREATE POLICY "email_aliases_select_admin"
+  ON public.email_aliases
+  FOR SELECT
+  USING (
+    COALESCE(((auth.jwt() ->> 'is_admin'::text))::boolean, false) = true 
+    AND has_aal2()
+  );
