A directory moved out of a watched tree kept its kernel watches, so later changes inside it were reported under the old path. Its watches and those of its subdirectories are now removed on `MOVED_FROM`. Watches the kernel reports as `IGNORED` are forgotten as well, so a reused descriptor number cannot map to a stale path.
