I’m still working my way through this update ( BTW it’s looking very good ), but an initial comment on the API.

The access modes of MemorySegment are a nice addition, but while reading the API alone, I find myself wondering what access modes are held by segments returned by the static factories. Most hold all access modes but not all, e.g. read-only byte buffer. AND a mapped segment with mapping mode READ_ONLY ?

Maybe it is worth specifying this? E.g something like:
