...With an oscillator built from inverting logic gates, you need two
gates so
there is no overall phase inversion through the gates.

There are two types of oscillators with gates. Series and parallel.
The former requires no inversion the latter does.

If you are using XOR
gates, I would recommend tying one of the input lines on each gate high

He said he was.

I think the biggest issue here is thr Schmidt input. It can't be
biased
*in the active region*.
