wallet – What is the version of the magic key for BIP49

I implements the BIP49 compatible key derivation for bitcoin-s, but I have trouble finding the magic version bytes to use for extended keys.

I have consulted BIP49, but I do not find anything there.

In addition, are there several schemas to derive P2WPKH-nested-in-P2SH? I've looked at BitcoinJ's Samourai fork, Trezor implementation and test vectors in BIP49, and I'm having trouble passing vectors using the Trezor / Samourai magic version bytes.

Perhaps I am confused as to the Samurai magic bytes that correspond to mainnet / testnet P2WPKH-nested-in-P2SH, so any clarification is appreciated here. From my understanding, the version bytes of the main network are 0x049D7CB2 (pub) and 0x049D7878 (priv) and testnet are 0x044a5262 (pub) and 0x044a4e28 (Priv).

Finally, any indicator for testing the BIP49 and BIP84 vectors is appreciated. Currently, I came across the BIP themselves, as well as on SLIP132.
