no oily residue to be found either on the back wall or evident in the drain pan itself

a leak could be anywhere in the system

Evaporator, Condenser, or the lines in-between (in the walls...)

a slow leak might not leak the oil....

I see your raise and I will   raise it to............................Going on the picture and knowing that the fresh food side is an off cycle defrost,  I would venture that the cold control is running too long.................... The frost keeps building up and not melting  off during the off cycle   ( when the cold control is satisfied )......... The fan cannot move air across the coils to cool the interior..............   The refrigerant could be low  but we will fix  the main problem first.....................Keep us posted...............

The cold control is a problem, but judging by the bottom rows having no frost, you are more than likely at the beginning stages of a leak, more than likely in one of the u-shape caps on the left side of the evap. Many times there is no oil residue when I detect a leak there.

so the majority feels that there is a slight leak in the sealed system. how long will it probably take before i see the end results of this leak? weeks, months?

fwiw, it is still doing fine as of right now, temp setting on 5, cooling to 34 give or take.

I could take a year or more, depending on the size (and location) of leak.

The Compressor  may start running continuously .. $$
