Module: Insika::Evals::PersonaLoader

Defined in:
lib/insika/evals/persona.rb

Overview

Loads + validates a persona mapping (the persona: key of a golden, or the --persona file of the simulate CLI). Fails LOUD on a malformed persona — a silently relaxed max_turns or a missing knows would produce a simulation that tests nothing.

Defined Under Namespace

Classes: InvalidPersona
