-    Heuristic:
-    - For directories: use ctime (most accurate for torrent folder creation)
-    - For files: use atime unless it's too close to current time (suggesting
-      the filesystem updates atime on reads), otherwise use max(mtime, ctime)
+        Best-effort rule:
+        - On Windows: use ctime (creation-time semantics)
+        - On other OSes: use mtime (ctime is metadata-change time on Unix)
