//! Integration tests for folder `default_permissioned_as` rules.
//!
//! These tests exhaustively verify the feature across every surface where a
//! `permissioned_as` / `on_behalf_of_email` default is applied at create-time:
//!
//! - folder CRUD (persistence, validation)
//! - audit log emission
//! - schedules, flows, scripts, apps — all entry points
//! - admin / wm_deployers / regular-user behavior
//! - create-only semantics (updates never rewrite)
//! - explicit preserve beats folder default
//! - first-match-wins ordering for overlapping rules
//! - stale rule rejection
//! - paths outside folders are untouched
//!
//! The tests share one workspace and one folder because ApiServer::start has
//! significant setup cost; keeping everything in one test minimizes total run
//! time while still exercising every branch.
