2909	magic-folder .backup files are wrong	meejah	daira	"The behavior of producing .backup files is wrong (and I believe the spec is correct). Currently, whenever we decide to download a file, a `.backup` is produced if there was already a file there.

But, consider the case where Alice and Bob share a folder, and Alice makes a series of updates to a file `foo`: on the first update, Bob downloads it and writes it; on the second, Bob downloads but already has one so makes a `foo.backup` as well; on the third, Bob downloads but already has one *and* a `foo.backup` so produces `foo.conflict`."	defect	closed	normal	undecided	code-frontend-magic-folder	1.12.1	fixed
