Not exactly (depending on what you mean by "perform"). Tracing can be
used to determine whether OPES is still in the loop. The trace does
not tell you whether bypass was considered but no non-OPES version of
the content was available (and so you should stop trying) or whether
bypass instruction was ignored (and so you might be lucky if you try
again, perhaps using a different path through OPES).
This is an important distinction to document. I do not know whether
it is important enough for us to require that the trace includes
"I tried but could not bypass" info.
