activityName
Analysed element's display name (e.g. example_activity) — the label of the diagram's outermost box. Wired from the module / DSL. Blank/unset ⇒ no element wrapper (matrix tests, ad-hoc runs). Together with elementAsil / elementType this builds a concrete Element passed to Enrichment.enrich(analyzedElement = …); linking to the real compiled Element instance is a follow-up.
