• calibratedParsingScore (type: float(), default: nil) - A parsing score that is independently calibrated by each parser/IG.
• intentNameAuisScoreExp (type: float(), default: nil) - Assistant User Interaction Score which is aggregated using intent name from exp laelaps.
• inQueryMaxEffectiveArgSpanLength (type: number(), default: nil) - This is a cross-intent feature which is calculated by iterating all intent candidates. This feature should be populated in post-IG stage (before GB).

• isPodcastGenericIntent (type: boolean(), default: nil) - Used for PFR manual rule to prefer high confidence podcast intent (e.g. topical, genre) over generic podcast intents.
