How about using a DAC driven from a uC, or even some clever bit of
hardware?

A uP with an ADC could measure the sine amplitude and an MDAC could
tweak loop gain. But you may as well just synthesize the sine wave
with a 20-bit DAC.

If you could somehow measure sub-PPM distortion, tweak that down in
the DAC data.
