TASK DESCRIPTION
  Some records appear to be missing from the dumps - is it possible the dumps 
are incomplete, or am I doing something wrong? I'm new, so my apologies if I'm 
doing something obviously wrong!
  
  **Steps to replicate the issue** (include links if applicable):
  
  1. Download the latest bz2 dump from 
https://dumps.wikimedia.org/wikidatawiki/entities/latest-all.json.bz2. At the 
time of this writing, that was the file produced on 25-Oct-2023 19:30, 
85,161,509,921 bytes in size.
  2. Search it for Q5085764: `lbzcat latest-all.json.bz2 | grep Q5085764`
  
  **What happens?**:
  
  There are no records found.
  
  **What should have happened instead?**:
  
  A record corresponding to https://www.wikidata.org/wiki/Q5085764 should have 
been emitted.
  
  **Software version** (skip for WMF-hosted wikis like Wikipedia):
  
  I'm using lbzip2 on Ubuntu 22.04. I also tried stock bzip2.
  
  (Aside: https://www.wikidata.org/wiki/Wikidata:Database_download says: "Note 
that the files are using parallel compression, which means that some 
decompressors cannot reliably unpack the files." It was not clear to me what 
this meant -- that some decompressors will decompress it correctly, but 
serially; or that some will corrupt the output. In any event, lbzip2 was one of 
the blessed packages for Unix, I think.)
  
  Thanks for any pointers you can offer!
