Question: is there any way for the 'examining' code, possibly running on a

In general, no.
The architecture only guarantees storage consistency if the data is in
the same double word, aligned on a double word boundary, in the general
case (such as using LM or STM) or the same quad word, aligned on a quad
word boundary, for a defined set of instructions (such as CDSG).
