A file only browsed in Local was counted as already in the library and
silently dropped; it is now new, and synchronizing brings it into the
library, as an import does.
A photo whose file was renamed or moved within the folder showed as
missing while its file counted as a skipped duplicate, so "Remove
missing" sent the photo and its edits to Recently Deleted and imported
nothing. The scan now matches a missing photo's content hash among the
folder's files and lists it as moved; synchronizing relinks it (on by
default, "Relink photos whose file was renamed or moved"), in the same
undo step.
