#autocomplete_collecting_event_object ⇒ Object

Matching by ENVO term alone can't distinguish two assertions with the same uri_label on different objects (see asserted_environment_tag), so also let the object's own label reach its AssertedEnvironments - one subquery per polymorphic type, each delegating to that object's own (already comprehensive) Autocomplete class rather than reimplementing a narrower match here.
