Feature

A Feature is a group of Scenarios about the same consistency unit. Picking one consistency unit per Feature is the structural rule that keeps Scenarios focused: when you find yourself wanting to mix Scenarios about an Aggregate and a Process Manager, you have two Features, not one.

A Feature has four variants, one per kind of consistency unit it can target: Aggregate, Dynamic Consistency Boundary, Process Manager, or Read Model. The variant determines the shape of every Scenario inside the Feature.

Why Events Are Referenced Differently per Variant

Aggregate Features identify Events by bare name because the Feature already fixes the producing Aggregate. Dynamic Consistency Boundary, Process Manager, and Read Model Features carry full Event references because their preceding Events may originate in other Bounded Contexts.

A Feature is therefore not just a grouping mechanism – it is a frame that determines what kind of facts the Scenarios inside it can talk about, and how.
