Query: Fermions in worldline holography   We analyse the worldline holographic framework for fermions. Worldline
holography is based on the observation that in the worldline approach to
quantum field theory, sources of a quantum field theory over Mink$_4$ naturally
form a field theory over AdS$_5$ to all orders in the elementary fields and in
the sources. Schwinger's proper time of the worldline formalism automatically
appears with the physical four spacetime dimensions in an AdS$_5$ geometry. The
worldline holographic effective action in general and the proper-time profiles
of the sources in particular solve a renormalisation group equation. By taking
into account sources up to spin one, we reconstruct seminal holographic models.
Considering spin two confirms AdS$_5$ as consistent background.
