with apologies to those who aren't interested ;-)
For a plucked instrument the finger on the node is removed from the string just
after the pluck. (otherwise the sound is damped)
Indeed, having sharp harmonics is a property of all strings outside the physics
lesson, as any piano tuner knows.
Also, if you use an oscilloscope to view the waveform, and hit the harmonic
partially so that some of the fundamental also sounds, you can see the waveform
of the harmonic moving against that of the fundamental.
For a bowed instrument, I suspect the harmonics are in tune as long as the bow
is driving the string.

That may be true, but a more obvious cause would be that the total
length of vibrating string is reduced by the width of the area of
contact of the finger.

They would be for a perfectly thin flexible string - but string stiffness
sharpens the higher harmonics.

Harmonics on a plucked string are a little bit sharp,
Isn't it the case that harmonics are pure by definition?
