How are these values obtained or updatable based on what in the future?

I.e, are these values always the same for any pre-image proposing authorising a runtime upgrade? Or do we need to keep changing them? If so, what's the best way to do that? I am 90% we don't, but just want to double check.

I will definitely improve the name to something like AUTHORIZE_UPGRADE_PREIMAGE_LENGTH_BOUND. Regarding the value itself: The WASM code of authorize_upgrade(code) is hashed with H256 which encoded to 32 bytes. I remember to have tried with 32 as bound as well and failed, so I suppose the other two are some wrapper bytes.

Hope 71da5cd brings sufficient clarity

I guess the "2 extra" bytes is the first for the pallet index and the second for the extrinsic index?

Leaving this one here and I feel this is really something missing in the polkadot dev ecosystem: https://ruudvanasseldonk.com/2022/03/20/please-put-units-in-names
