Default Simplified Twin Paradox Resolution.

do you not see that the angular momentum
of atoms, has to be condsidered if a prefered direction
is taken?

taht is to say, lightwaves do not have a velocity,
only a speed.

Situation IS asymmetrical if we tag a frame that undergoes actual
acceleration. But this is against the basic principles of SR which
deals with uniform relative motion and nothing else.

my main concern, for using diadians (or tau) is that
the simplicity of (viz) radar distances is obscured;
also, how to avoid confusion with radians (or "pi+pi"),
since pi is generally considered to be a dimensionless constant,
by some argument or other.

--yay; a new proof of Fermat's 'little' theorm!
