Convex model symplectic contact frame independent

The normalized convex model symplectic contact frame is linearly independent at every sphere point.
All displayed regularity, tangency, normalization and supplied-data hypotheses of the exact formal statement are retained. This is a conditional result for the defined convex regularization model, not a global-section or index-existence theorem.
