1Places, Never People
Only places are measured. There is no score for a person, and no leaderboard of people, anywhere in the system.
2A Privacy Floor of Five
A figure drawn from fewer than five people is withheld, and so are any figures that would let someone work it out by subtraction. A withheld night shows as a gap, never as a zero.
3Snapshots, Never Live Counts
The Atlas reads a nightly summary. A live count would let an observer watch individuals arrive one at a time.
4On the Map Only by Choice
The map is designed to plot a person only if they opt in, and then only as one nameless point snapped to a coarse grid. The default is off, and the opt-in control is not yet wired in the demo.
