Is there a theorem saying that if the metric starts out with a
negative signature on a spacelike surface (one or three eigenvalues
negative) that the field equations will preserve this negative
signature for all future and past?

No. The Spacetime equation is a short cut to write down all the
equations of the Lorentz transform into one single equation. It was a
lazy-man's way of doing so, but over the years, it became a Gospel
treasured by the SR and the GR worshippers.

That's right, when I suggested General
Covariance enables a signature choice,
to unchain the brains, I got yelled at.
It's a psychosis, some people want to
remain chained up and imprisoned so I
figure to allow that, it's a choice.
Most people are more comfortable being
being tied up, and that's good, keeps
the poop off the sidewalks.
