Measure realistic bounded and live stream publication

Parent

A small repeatable baseline identifies notification, retention, and publication cost for realistic streams.

Compare bounded/unbounded accumulated data, live values, and relevant structural-sharing choices using fixed numeric/object workloads.
Record cache notifications, retained-data/allocation evidence, and focused existing-example rendering observations where useful.
Explain history versus transport buffering versus publication rate, and document bounded/live choices for long-running workloads.
Record toolchain/fixture context and avoid universal wall-clock thresholds or changing defaults to win the measurement.
