//! The process-wide [`AiService`] handed to every consumer of [`AppContext`].
//!
//! One service per process: its audit tasks are never closed, they drain with
//! the runtime. A catalog without a usable default provider (a bridge-only
//! deployment, say) yields `None` after a single warning, so boot never
//! depends on inference being configured.
//!
//! [`AppContext`]: crate::context::AppContext
