//! Policy types for tool sandboxing.
//!
//! `PolicyToolSetProvider` and `SandboxMode` live in
//! [`crate::tool_set_provider`]. L1 policy types (`FsPolicy`,
//! `ShellPolicy`, `PolicyConfig`) live in [`super::policy_sandbox`].
//!
//! This module is a documentation anchor so the tool-module split
//! is complete.
