-- Migration 000044 down: drop audit_logs table.
--
-- DANGER: This drops the audit_logs table. All durable RBAC and
--         resource-action history is lost UNRECOVERABLY. Only intended
--         for development rollbacks, never for production.
--
-- Operators who really need to run this in a non-dev environment must
-- set the session-level GUC `weknora.allow_destructive_migration` to
-- 'true' first. Otherwise the migration aborts before touching any data.
