The low Db of a bassoon has no fundamental in it. And yet, it works fine
when the players creates the image of a fundamental through an emphasis on the
notes lower end. It's hard to explain, but there are some studies on this note
in the literature.

A harpsichord string may or may not have different degrees of inharmonicity.
Still, a tuner can hear what the centered pitch is on a given string and
match it to the pure octave above, even if there are some "not-perfectly harmonic"
harmonics along for the ride.

this is straightforward virtual pitch, as i've discussed here plenty
of times. no inharmonicity at work here.

the perceived pitch, which is a compromise of the information from
the fundamental and the harmonics, right?

sure, since you agreed that "pure" can simply mean "least beating".

including the fundamental!
