This looks to be what happened. When I had downloaded the file it was currently the "latest" version. I've since gunzipped it, so I don't have the original md5sum, but the timestamp on the file I have is before the Phabricator issue was opened so there's a good chance this is one of the "bad" dumps.

Thanks much for your help!

I checked my local copy of enwiki-20160407-pages-articles.xml.bz2 and
all those articles are present. For reference, my copy was downloaded
on 4-27, has a size of 12,878,552,649 and an md5 of

found the page:

Did you download your dump earlier last month? There was a known bad
version that was truncated by about 2 GB (somewhere around 10.8 GB).
It was missing most of the pages in the Module namespace, and may have
been missing these as well. See:
https://lists.wikimedia.org/pipermail/xmldatadumps-l/2016-April/001301.html

If yours is 10.8 GB, then you should redownload the latest version.
The modified time haven't changed, but it has been updated. See:

Hope this helps.
