1//! [`StatisticsPort`] — operational counter surface.
2//!
3//! Every [`DeliberateUseCase`](super) invocation that completes
4//! records its duration and specialty through this port; every
5//! [`OrchestrateUseCase`](super) invocation records the orchestration
6//! duration. Adapters decide where the numbers live — in-memory for
7//! a single replica, external store for multi-replica setups — and
8//! whatever Prometheus / gRPC exposer the composition root wires
9//! reads [`Statistics`] through `snapshot`.
