1//! Context-preparation vocabulary shared between the runtime and the
2//! plugin host. The concrete strategy (rolling history, overflow
3//! recovery, `/compact`) lives in
4//! [`crate::plugin_builtin::rolling_history`] and is dispatched through
5//! the [`TurnContextTransform`](crate::plugin::TurnContextTransform) and
6//! [`HistoryRewriter`](crate::plugin::HistoryRewriter) plugin capability
7//! surfaces.
