**Header:** `ClikaRT/runtime/context.h`

Context for a `RunOnce` phase ([`Model::Phase_RunOnce`](./Model.md#Phase_RunOnce)). Read [`inputs`](./PhaseContext.md#inputs), write [`outputs`](./PhaseContext.md#outputs); [`state`](./PhaseContext.md#state) is the session's state (null for a stateless model). All pointers are valid only for the duration of the call.
