Description
Just because it was simple to leave in, I left in the "DMRG noise term" feature in the tdvp function for the 2-site case. But it's unclear whether it's a good thing to turn on for TDVP. Some preliminary tests show it still gives correct results for very small noise <= 1E-11.
What's needed is to test that the noise can actually help in some tough case, and if so what size of noise is good to use.

Research direction
The tdvp function's 2-site DMRG noise-term path is the entry point; begin by reviewing it and reproducing the preliminary results for noise <=1E-11. Done means a tough-case comparison establishes whether noise helps and identifies a suitable noise magnitude.
