BIP86 singlesig taproot is currently guarded on the Liquid app: SIGN_PSBT rejects any taproot input outright (if (IS_LIQUID) SEND_SW(dc, SW_NOT_SUPPORTED) in src/handler/sign_psbt.c), even though GET_WALLET_ADDRESS already accepts tr(@0/**).
This issue tracks lifting that guard and implementing key-path taproot signing support for Liquid..
