When a match lives in another folder than the master (e.g. Game Rips/ vs
Video Games/), linking creates the new link at the master's path and then
removes the original. That removal re-checked the original's modification
time, which FUSE filesystems such as Unraid's /mnt/user can report
inconsistently; the check then failed after the link was already made,
leaving both files and a failed operation whose quarantine copy was hidden.
- Once the original is quarantined, verify it by identity (same inode as
the quarantine copy) instead of by timestamp. Identical files without a
quarantine copy keep the strict check, now with a detailed error.
- If the original still cannot be removed, roll back: remove the new link
and the unneeded quarantine copy so nothing changes. If the original was
swapped for another file mid-way, its quarantine copy is kept.
- Linking again when the master's path already holds a hardlink of the
master only retires the leftover original, which cleans up files left
by the old behaviour; undo then keeps that pre-existing link
(migration 5 records this).
- Promote gets the same identity check and rollback.
