Has the Sentencing Commission overstepped its congressional authority granted it under 28 U.S.C. § 994 when, with no specific congressional directive given, the Commission expanded the definition of 'minor', already codified under 18 U.S.C. § 2256(1), to include undercover law enforcement officers posing as a person under the age of 18 years?

Can the Sentencing Commission use its own amendment process to change unambiguous definitions Congress has already codified instead of seeking and being granted a specific congressional directive to do so?

Can U.S.S.G. § 2G2.2(c)(1) be applied based on the Sentencing Commission's definition of 'minor' when only an undercover law enforcement officer posing as a person who has not attained the age of 18 years is involved?
