Your triple combination index summarizes,
Mosiah 2:36–37 as follows “man who transgresses against his knowledge comes out in open rebellion against God,”. I will grant that the verses themselves go into more explicit detail, and may sound like they describe some major apostasy, but the Institute manual does not interpret it that way:
Mosiah 2:34–41. Willfully Rebelling against God
• When a person knows what is right and does not do
it, he or she not only violates the actual law, but puts
himself or herself in a state of opposition to God—a
serious offense in and of itself. President Gordon B.
Hinckley (1910–2008) shared the following simple
illustration of such rebellion: “I recall a bishop’s telling
me of a woman who came to get a recommend. When
asked if she observed the Word of Wisdom, she said that
she occasionally drank a cup of coffee. She said, ‘Now,
bishop, you’re not going to let that keep me from going
to the temple, are you?’ To which he replied, ‘Sister,
surely
*you *will not let a cup of coffee stand between
you and the house of the Lord’” (in Conference Report,
Apr. 1990, 67; or
Ensign,
May 1990, 51).

Sin is breaking a commandment, or going contrary to the [w]ill of God, when one knows better. Rebellion against God, according to this, is going contrary to the will of God when one knows better. Sin=rebellion against God.
