The fee lives in the mint
The 3% is not a contract rule layered on top; it is a transfer-fee extension baked into the mint when it was created. Move the token anywhere, by any route, and the mint itself keeps 3% back. Nobody holds a key that edits that number, because the mint has no owner to hold one.
