 Wouldn't it be great if the text that said "12 repairs attempted, 11
 successful, 1 failed" had hyperlinks to web pages that listed all of the
 repair attempts, where you could see which file was not healthy, which
 servers the repair job attempted to use to repair the file, and what
 happened with each server that led to success or failure?

 Providing such a web page would mostly just be a matter of "web
 programming" -- generating HTML that shows the contents of the Python
 objects in memory which contain that data.

 Here's the data stored in Python objects in memory:
