The neural network of the stockfish chess engine
You don't need to care about possible games, but game states, what's the best result and the move to achieve it in each. Another user computed an upper bound at 8.7E+45 positions: https://github.com/lechmazur/ChessCounter . I pointed out that our planet has about 1E+50 atoms. And we can further compress the database by perhaps two orders of magnitude if we don't store symmetric positions or positions close to mate. A Kardashev 2 civilization could play perfect chess.
- Accurately calculating the number of legal chess positions
- There are 8590000000000000000000000000000000000000000000 legal chess positions

Building My Own Chess Engine – Andrew Healey
"Claude Shannon calculated that there are around 10^120 possible games of chess in his seminal paper Programming a Computer for Playing Chess in 1950. "
I've just finished a weekend project to calculate the number of legal chess positions and there are about 8.5E+45: https://github.com/lechmazur/ChessCounter.
For people considering making a chess program, take a look at this message board http://talkchess.com/forum3/index.php.

- Discussion on whether a buffer overflow bug involving illegal positions in Stockfish (#1 ranked chess engine) could lead to remote code execution on the user's machine

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.

What makes SF15 better than 14? I mean, what do they do/program to improve performance?
You can see the various code changes in https://github.com/glinscott/fishtest/wiki/Regression-Tests . Both the actual change and the elo change from the code change.
