"Baggage Clearance regulations::
Baggage is cleared at the first airport of arrival in Ireland (Rep.).
Exempt: baggage of passengers with an onward connection to Cork (ORK), Dublin (DUB), or Shannon (SHN); baggage of passengers who embarked in another EU Member State , baggage of transit passengers with a destination outside of Ireland (Rep.)."
It doesn't appear you meet the exemption as your destination is CFN.
IATA is the publisher of the TIM (Travel Information Manual) which is the bible for airline staff world wide. I would trust it.
