// Reference witness: the OCEL event identity surface and typed event-attribute
// builders (COVERAGE.md §2 — OCEL event perspectives).
//
// OCELEvent carries an (id, event_type) identity pair constructed via
// OCELEvent::new. OCELEventAttribute is a (name, value) pair where the value
// lands in the typed OCELAttributeValue union; the string/integer builders map
// to the correct variant and preserve the name field verbatim.
