So a ‘mutable property’ would be one that is unset by default?

My understanding is that immutable properties store default values--such as a procedure to be applied when calculating Stem.thickness or whatever, and immutable properties store the results of calculations for a particular instance of a grob--for example, the value obtained by applying the default procedure to a certain Stem.

These terms are defined here (a bit cryptically I think):
Cryptically indeed :-)

  You'll note that each of the other properties you offset has a default value in scm/define-grobs.scm
As a side note: I find it confusing that these are not to be found in the IR.

But they are--for example, is built from the entry in scm/define-grobs.scm.
Where do I have my mind? …

Good night,
