What is the roll mode on the FMA before takeoff if LNAV is not armed on the ground?

Roll mode indicates which lateral command is guiding the aircraft. If LNAV isn’t armed on the ground, there’s no active lateral guidance, so the FMA roll mode is blank. This means the system isn’t providing a roll command yet, and nothing will appear until a lateral mode (like LNAV or HDG) is armed. TOGA or CLB are thrust or pitch-related modes and wouldn’t show up as a roll command in this scenario.
