Assim eu diria em PT-Br. Não sei se faz sentido em PT-Pt. Minha tradução deriva de um exemplo encontrado (v. abaixo) e na seguinte explicação relacionada à dramaturgia:

"Front stage:
Within society we are expected to present ourselves in a certain way, however, when a person goes against the norm society tends to notice. Therefore, we are expected to put on a costume and act different when in front of the audience. Goffman noticed this habit of society and developed the idea of front stage. In his book The Presentation of Self in Everyday Life, Goffman defines front as "that part of the individual's performance which regularly functions in a general and fixed fashion we define the situation for those who observe the performance. Front, then, is the expressive equipment of a standard kind intentionally or unwittingly employed by the individual during his performance" (486).[10] During the front stage, the actor formally performs and adheres to conventions that have meaning to the audience.[9] It is a part of the dramaturgical performance that is consistent and contains generalized ways to explain the situation or role the actor is playing to the audience that observes it. The actor knows he or she is being watched and acts accordingly.[9] This is a fixed presentation. This concept can be seen in the 2005 film Waiting. The servers have to act much more proper and presentable in the dining room than they do in the kitchen. Goffman says that the front stage involves a differentiation between setting and personal front. These two concepts are necessary for the actor to have a successful performance. Setting is the scene that must be present in order for the actor to perform; if it is gone, the actor cannot perform." - https://en.wikipedia.org/wiki/Dramaturgy_(sociology)#Front_s...

O Priberam registra / regista o verbete "performático" como sinônimo de performativo:
https://dicionario.priberam.org/performático

No Brasil, a expressão “de fachada” é uma maneira coloquial para dizer que algo que é tornado público (um projeto, uma política) sem que todos os elementos estejam revelados.

"Atividade política pública e manobras/atividades de bastidores"

Diria assim, dada a definição de "frontstage politics" e "backstage politics".

Política mais exposta, cujas práticas são mais perceptíveis ao público.

"... research which distinguishes between spaces of ‘frontstage’ and ‘backstage’ politics and the interactions between the two. (...) Rendering these micro-processes of politics more visible...".
