Signature doesn't prove that the owner of a Private Key produced a given message
“Slightly” I suppose is right in the scale of the numbers :P

In BIP32 yes. BIP39 is a specification of seed mnemonic encoding, not deterministic key generation.

No, only values which meet the specification for secp256k1. Approximately
2^256-2^32
total keys are valid.

What hardware do pool operators use for calculating the hashmerkleroot?
Antminer machines contain an entire linux computer, the ASIC is not producing the merkle root.

What hardware do pool operators use for calculating the hashmerkleroot?
Whatever local hardware is controlling the ASICs, usually a normal machine running linux, sometimes offloading some of the hashing to a FPGA.

They conflict with another transaction in the mempool, but this does not make them invalid.

What would happen to Bitcoin if GPS/Galileo timing ceased to be available?
The white paper is really an overview of the system, most of the things aren’t really spelled out as such. I don’t know of a reference for how timing works.

Is multisig wallet simply a combination of many singlesig wallets?
I didn't comment on that in particular. Just in general if you try to do unsupported things with wallets the chance of you losing money in a way nobody can recover is extremely high.

Unless tools actually support things explicitly, this sort of experimentation is a very good way to irreparably lose your money.
