Defined in:

Overview

NullEvidenceSource is the default evidence source — purely classifier-driven, no corpus signal. The Normalizer's mechanical behavior is what this produces. Implements the same render_query interface that Corpus implements for the corpus-informed path.

#render_param(name, value, classifier) ⇒ Object

One param's mechanical rendering. Corpus#render_query delegates here for params it lacks evidence on, so the two paths can't drift.
