Separated Witness – What private keys are used for Taproot transactions?

The transaction has only one input and the scriptPubKey is –> Op_1 Q. Where Q is the adjusted public key.

p = private key, P = public key, q = p + adjusted, Q = adjusted public key

To create a transaction, you need to fill in the watch fields.

1. Spend key path: Do you use q (the adjusted private key) to sign the transaction?

   that, s = k + H(R, Q, txdata)q and The symbol is (R,s). where K Nonce is

2. Spend script path: Do you use p (unreconciled internal private key) to sign the transaction?

   that, s = q + h(Q,P, txdata)p and The symbol is (Q,s). where cue Now it’s a nonce

Finding an answer to this was difficult for me because I’m not a coder and I think I need coding to understand how the mechanism works.
