Public Interface

Method	Signature	Description
WhereIf<TSource>	static IQueryable<TSource> WhereIf<TSource>(this IQueryable<TSource> query, bool? condition, Expression<Func<TSource, bool>> truePredicate, Expression<Func<TSource, bool>>? falsePredicate = null)	Applies truePredicate when condition is true, optional falsePredicate when false, no-op when null

Internal Logic

If condition is null, returns the query unmodified. If true, applies truePredicate. If false and falsePredicate is provided, applies it; otherwise returns unmodified query.
