First, don't panic. Harris and her staff, and Democrats around the country, they have planned for many shady actions on Trump's part. Details are scarce because they don't want Trump staff to have a heads up.
And then everything depends on the details.
But remember, anything that looks like a coup d'etat could easily get the military or spy agencies involved. And if they move, it doesn't matter what SCOTUS says. As a result, it's very hard to predict what would happen in various extra dramatic situations. There is no precedent; precedent wouldn't mean anything anyway.
