Mikoshi Cores
Two rows of cores numbered 0-7. The left side is surrounded in blue squares, while the right is surrounded in red. A judgment card split down the middle is nestled behind them, with an overwhelming sense of symmetry/asymmetry at play.
The Strange Symbol
I've traced the symbol that appears on each of the cores here for easier viewing:
The Ambassadors (Holbein)
The symbol upon initial inspection seems rather tall. I've seen stretched symbols before in the world of art - an example being "The Ambassadors".
Processing the Symbol
By viewing the core symbol in the same way, we can attempt to destretch it and analyze it further:
Ultimately it seems that these symbols are pointing to the hidden "Don't Fear (The Reaper)" ending existing, by expressing 4 pyramids instead of the 3 we knew about prior to this ending path coming to light.
Similar Structures
Mega Buildings
The cores are very similar in architecture to the mega buildings that dot the landscape of Night City. There are 8 cores, and there are 8 mega buildings that are not inaccessible.
Arasaka Estate
The heated outdoor seating area at the Arasaka Estate also shares some very notable architectural similarities with the cores. Seeing a fire underneath the obilisk reminds me that we "have a city to burn".
