If the sine frequency is f and the sample rate is sr:
Let C = cos(2*pi*f/sr)
For each sample compute:
y(t) = x(t) - 2*C*x(t-1) + x(t-2)
y(t) should be 0 for every t... if not it indicates a discontinuity. This
is just an FIR filter with a zero at the given frequency.

With any phase discontinuity, a spectral discontinuity is delivered for free.
So, the notch filter will have an output, a PPL would need to re-sync, etc.

Maybe try locking a PLL to the sinewave to get the expected frequency
and phase, then look for differences between them?

A notch filter would
A notch filter would serve you well, if the sine wave doesn’t change its
frequency.
