Query: Two variations on the theme of Yang and Mills -- the SM and the FSM   The standard model (SM) is viewed as a variation on the Yang-Mills theory
with gauge symmetry $u(1) \times su(2) \times su(3)$, in which the flavour
symmetry is framed and to which 3 generations of quarks and leptons are
appended as inputs from experiment. The framed standard model (FSM) is then a
further variation on the SM in which the colour symmetry is also framed, where
the 3 generations now follow as consequences together with their characteristic
mass and mixing patterns. In addition, the FSM yields as a bonus a solution to
the strong CP problem leading to a unified treatment seemingly of all known CP
physics for both quarks and leptons. It predicts, however, also a "hidden"
sector populated by particles yet unknown, hence full both of promises (e.g.\
dark matter?) and of threats, which is just beginning to be explored (i) with a
modified Weinberg mixing and (ii) with the $g-2$ and some other anomalies.
