Our proof seems to have escaped the attention of Hilbert (and all subsequent workers) [but alas turned out to contain a severe gap, cf. Introduction for more!]. It uses a bit Poincar\\'e's index formula (1881/85). The method applies as well to prohibit Rohn's scheme 10/1, and therefore all obstructions of Hilbert's 16th in degree $m=6$ can be explained via the method of total reality.
