Nitpick: detail messages should end with a period per the error message style
guide [0].

-    archiving will proceed only when it returns <literal>true</literal>.

I think this paragraph needs to be updated to include how the returned
logdetail is emitted, since it currently shows the WARNING without mentioning
the added detail in case returned.  It would also be good to mention that it
should be an allocated string which the caller can free.
