1//! Per-provider AI policy and per-model descriptors.
2//!
3//! [`AiProviderConfig`] is the deployment policy layered on a registry provider
4//! (enable flag, default-model overrides, resilience). [`ModelDefinition`] and
5//! its [`ModelCapabilities`], [`ModelLimits`], and [`ModelPricing`] are the
6//! per-model descriptors shared with the services provider registry.
7//! Connectivity itself is never modelled here — it lives in the provider
8//! registry.
