+-- Ensure ak_users has a primary key and chat tables reference it consistently
+-- This script can be executed on Supabase/PostgreSQL to harden chat user relations
+--
+-- Steps:
+-- 1. Add a primary key on public.ak_users(id) if it is missing.
+-- 2. Backfill missing ak_users rows from auth.users so foreign keys can validate.
+-- 3. Recreate chat_* foreign keys that point to ak_users.
