cached ever, yes.
cached now, no.
If you want a comprehensive list of all things cached now use the cache
manager "objects" and "vm_objects" reports.

Your first statement answers your second question. "which have been
stored on disk"

No store.log is a log for maintenance debugging of problems in the
storage cache. Not a long term record.

No. It is possible to achieve using a custom access.log though. Add the
header "Cache-Control: only-if-cached" to your agents requests, and do
not log requests made by that agent to the log being used by it.
Oh, and why do you need to do this in the first place? it will cut your
network performance in half.
