+# Redeploy after the remote bundle directory is deleted out-of-band (e.g. a user
+# deletes it in the workspace UI).
+#
+# After such a deletion the next "bundle deploy" does not re-upload the bundle files:
+# the local sync snapshot still records them as present remotely, and the remote
+# deployment state that would otherwise reset the snapshot was deleted too, so the
+# file sync computes an empty diff and uploads nothing.

+# This test pins down the current behaviour: hello_world.py is missing from the

+# sync is changed to re-upload in this case, the final get-status will succeed and
