As far as I understand the question it seems to me that the answer
is "intensional recursion theory". My own approach to epistemology
has been based on it, especially through the work of John Case.
Fortunately or unfortunately, the modal logics of self-reference (G, G*)
can be used as a sort of shortcut so that I am no more relying
directly on the, although very beautiful, work by John Case.
A good starting point is
Note that it is not really "first person perspective of a mirror", at least
as I define "first person" because "my" first person is just invisible
for all third persons and so cannot be seen in a mirror.
First persons share this property with vampires!

One day I will put my paper "amoeba, planaria,
and dreaming machine" on my web page, because it shows the relationship
between Case's use of the mirror in abstract biology and the loebian machine

Hoping that helps.
