The time between the first Calment death and Calment becoming notable is long enough - over 50 years - that it's plausible that people who were in on the scam/aware of the assumption of the mother's identity had already died. Especially since ww2 happened in the interim
Raffray is the biggest sticking point in this fwiw - he had time and incentive to debunk Calment's age, and had some preexisting relationship with her before they entered their contract.
