* With the download process after data is downloaded it is copied to object storage, immediately after
* When the download process starts before it attempts to retrieve data from object storage first before going to its official sources
* When processing starts, it determines what needs to be done based on what data exists in the object storage

Start by tracing the download and processing flows described in the issue, including where downloaded data is copied and where processing determines its work. Done means downloads check object storage before official sources, completed downloads are stored immediately, and processing resumes based on the data present there.
