In particular, it calls solve_for_matrix_and_rhs() at each time step, which uses the solution vector. Note also that there is a boolean compute_truth_projection_error that can be used to compute the error between the RB solution and FE solution (that is used in the RB training), so you might want to look into that, and the set_error_temporal_data() function. You'll have to dig around in TransientRBConstruction a bit in order to do what you want, I think. Note that the TransientRB code hasn't had much attention lately, so if you want to make any updates or improvements to the code, please feel free to submit a PR.
