AnyStat

A Stat over an unspecified Result type. The star-projected base shared by every concrete accumulator in this package, useful when handling a heterogeneous bag of stats whose result types differ; a registry, a fan-out over a mixed schema, or generic plumbing that only calls read / merge / reset.

For a stat with a known result type, refer to Stat (or a modality subtype such as com.eignex.kumulant.core.SeriesStat) with its concrete R.
