You have had to go out of your way this past year to not be familiar with the state amendment process.
States will send delegates with commissions. Commissions set out in precise terms what the delegate may propose and accede to. Delegates are the equivalent of agents with power of attorney to carry out certain duties and no more. The commissions of Indiana and IIRC, Florida include the caveat that if a delegate oversteps his bounds, the state declares his action null and void. In addition, these trusted men or women will face felony charges should they attempt such shenanigans.
Who gets to decide on the Delegates? Who is in the pool of delegates?
I am familiar with the process, I am just not naive. I have been inside to many organizations, to many caucuses, to many committees not to know that such things are easily hijacked, and hard to restore.
