When a document is saved multiple times quickly, each save registers its ImgDat UUID in a ConcurrentHashMap. The async reconversion task checks this at 6 checkpoints (before start, after download, after PDF conversion, after PDF upload, before thumbnails, after thumbnail generation). If a newer save has replaced the expected ImgDat, the task exits immediately without writing stale results or orphaned records.
