-- Mock Supabase auth schema for local migration testing.
-- In real Supabase, the auth schema + auth.users table + auth.uid() function
-- are created by the platform; locally we simulate them.
--
-- Usage: psql <DATABASE_URL> -f internal/db/migrations/_dev/mock_supabase_auth.sql
--
-- For visibility tests, set the GUC paliad_test.uid in a transaction:
--   BEGIN;
--   SET LOCAL paliad_test.uid = '<some-user-uuid>';
--   SELECT paliad.can_see_akte('<some-akte-uuid>');
--   COMMIT;
--
-- _dev/ prefix excludes this file from golang-migrate's source pattern
-- (which only reads top-level *.sql in the migrations dir).
