//! Runtime performance a process measures about itself: its step cadence and
//! its per-topic bus accounting, rolled up over one window.
//!
//! The producing participant is the bus envelope's source attribution, so a
//! rollup carries no identity field of its own. Retained, replayable views over
//! these same samples belong to whatever host tool collects them; this family
//! owns only the live rollup and the sample vocabulary it is written in.
