Interested in creating, playing and testing your own chess engine?
you can have a look at openbench maybe, https://github.com/AndyGrant/OpenBench . It is currently a testing framework for chess engines (only invited ones) or fishtest. https://tests.stockfishchess.org/tests Stockfish testing framework. Both of these test if change A beats the master version using statistics. Both look at the git repository and download it and create/compile the engine, that might be another solution for you.

~20TBs on Striped Hard Drives / RAID0: What kind of hardware to support this setup?
FishTest has thousands of computers running 24/7 https://tests.stockfishchess.org/tests. Nerds at gcp,aws,universities burn thousands of GPU hours on lc0-client just to watch their GPUs warm up. They aren't just attaching 20tb of endgames to an old macbook.

Does (human + computer) combo beat computer?
if removing any rng from stockfish would gain elo it would be merged. If you think it gains elo feel free to submit a test to https://tests.stockfishchess.org/tests , but it doesn't so what your saying makes no sense.

What are some chess960 positions that are winning for white
Where did you get these numbers from? https://github.com/glinscott/fishtest/wiki/Regression-Tests shows an elo difference of 351.3 elo points. This is further exaggerated by the fact that sf9 lacks nnue and is particularly weak at the starting position and consequently 960 starting positions.
