SameAutoStakeHotkeyAlreadySet
The object or state already exists; treat the goal as met or pick a different target
The coldkey tried to set its auto-stake destination on a subnet to the hotkey that is already configured. Read AutoStakeDestination for the coldkey and netuid before calling; only a different hotkey is accepted.
Declared by the SubtensorModule pallet; it classifies to the semantic code already_exists.
