"Cumulative" is the running sum of the weekly-active counts above —
the only honest number the receiver can produce. Salts rotate weekly by design
so hashes from week N cannot be matched to week N+1; a true
"unique installs ever" figure is therefore not computable from
this data. An install that opts in and pings every week for a year contributes
52 to this number.
