Aha.
After researching more into
.caltrash, I now realize that the reason I had such a huge one is because I was doing a manual data migration recently due to bad beta OS bugs and couldn't do a proper Calibre export/import. Trying to simply "Add from folders and subfolders" from my (manually backed-up) 2,900 book Calibre Library folder into a fresh library resulted in Calibre creating duplicates for each format I had on disk, even with clicking "Yes" on "Assume all e-book files in a single folder are multiple formats of the same book?" prompt. I didn't realize that Calibre holds onto deleted books when I took several attempts at this and was bulk deleting bad imports in between!
(Note: I've only seen Calibre duplicate my books when trying to run this operation on my entire old Calibre Library folder. When I finally decided to do it in a series of smaller chunks, no issues with duplication.)
