The beginning of the type in which the field is contained, which I think
means, in your parlance:

the "direct context".

In other words, if C has a field of type B at offset 32, and B has an
field "f" with offset 16, then the offset of B::f relative to C is 48.
(That's the only thing that makes any sense; otherwise, we'd have to
make a copy of B every time it appeared as field in some other type.)
