An object without backups.cozystack.io/endpoint stopped counting as
stale as soon as one forced render had been requested, whether or not
that render succeeded. A failed upgrade left the objects unannotated
and the gate silent until the controller restarted, which also hid the
climbing force counter meant to report exactly that failure. Such an
object now stays stale until a render stamps it; MinForceInterval
already bounds the cost.
