-- ============================================================
-- Migration 056: Definitive RLS fix
--
-- Root cause: (select auth.uid()) inside a policy that queries
-- org_members triggers PostgreSQL 42P17 infinite recursion,
-- because org_members' own SELECT policy also queries org_members.
--
-- Fix (per Supabase docs tip #4 & #5):
--   1. Create SECURITY DEFINER helper functions that bypass RLS
--   2. Use those in all policies — no self-referencing, no recursion
--   3. Wrap function calls in (select ...) for InitPlan caching
-- ============================================================

-- ============================================================
-- STEP 1: Create helper functions (SECURITY DEFINER = bypass RLS)
-- ============================================================

-- Returns all org_ids the current user belongs to
CREATE OR REPLACE FUNCTION public.get_user_org_ids()
RETURNS SETOF uuid
LANGUAGE sql
STABLE
SECURITY DEFINER
SET search_path = ''
AS $$
  SELECT org_members.org_id FROM public.org_members WHERE user_id = auth.uid();
$$;

-- Returns the user's role in a specific org (or NULL if not a member)
CREATE OR REPLACE FUNCTION public.get_user_org_role(org_id uuid)
RETURNS text
LANGUAGE sql
STABLE
SECURITY DEFINER
SET search_path = ''
AS $$
  SELECT role FROM public.org_members
  WHERE org_members.org_id = get_user_org_role.org_id AND user_id = auth.uid()
  LIMIT 1;
$$;

-- is_org_member already exists from migration 039, just ensure it's correct
CREATE OR REPLACE FUNCTION public.is_org_member(org_id uuid)
RETURNS boolean
LANGUAGE sql
STABLE
SECURITY DEFINER
SET search_path = ''
AS $$
  SELECT EXISTS (
    SELECT 1 FROM public.org_members
    WHERE org_members.org_id = is_org_member.org_id
      AND user_id = auth.uid()
  );
$$;

-- Returns true if user has editor+ role in the given org
CREATE OR REPLACE FUNCTION public.is_org_editor(org_id uuid)
RETURNS boolean
LANGUAGE sql
STABLE
SECURITY DEFINER
SET search_path = ''
AS $$
  SELECT EXISTS (
    SELECT 1 FROM public.org_members
    WHERE org_members.org_id = is_org_editor.org_id
      AND user_id = auth.uid()
      AND role IN ('owner', 'admin', 'editor')
  );
$$;

-- Returns true if user has admin+ role in the given org
CREATE OR REPLACE FUNCTION public.is_org_admin(org_id uuid)
RETURNS boolean
LANGUAGE sql
STABLE
SECURITY DEFINER
SET search_path = ''
AS $$
  SELECT EXISTS (
    SELECT 1 FROM public.org_members
    WHERE org_members.org_id = is_org_admin.org_id
      AND user_id = auth.uid()
      AND role IN ('owner', 'admin')
  );
$$;

-- ============================================================
-- STEP 2: Drop ALL existing policies on all public tables
-- ============================================================
DO $$
DECLARE
  r record;
BEGIN
  FOR r IN
    SELECT schemaname, tablename, policyname
    FROM pg_policies
    WHERE schemaname = 'public'
  LOOP
    EXECUTE format('DROP POLICY IF EXISTS %I ON %I.%I',
      r.policyname, r.schemaname, r.tablename);
  END LOOP;
END;
$$;

-- ============================================================
-- STEP 3: Recreate ALL policies using helper functions
