i have confirmed that this bug occurs as follows.
archiving commands append to a buffer for the archive. they do not
save, revert, or kill that buffer. my shell workaround, to allow
archiving given completely unusably slow archiving, moved the archive
files [so that they would not be slow].
therefore there were no archives on disk. but a full buffer.
therefore, archiving appended to existing buffers that did not match
what was on disk. then saved. ergo duplicates.
suggested fix: kill the archive buffer before appending to it, if it
is marked as unmodified.
if it is not marked as unmodified, maybe it is ok to append? idk.
