Transparence & contrôle public
Even though there is a main navigation item called “Transparence & sources”, this page under Gouvernance FRUPwould explain the governance principle. The other section would host the documents themselves.
Possible subtitle:
Rendre compte publiquement de la mission, des finances et de l’état du site.
It could explain that the Foundation would publish:
annual activity report;
financial report;
environmental report;
heritage report;
infrastructure condition report;
stakeholder consultation summaries;
conflict-of-interest register;
major contracts or summaries of major contracts.
Then link to Transparence & sources for the actual documents.
