Pica names every watcher. Mystery hosts stay mysteries.
01
Named, not numbered
Every tracker gets a name and a one-line confession of what it does.
02
Strangers listed
Hosts nobody recognizes get their own list, not a shrug.
03
Tarsier passes
Our own tracker shows up as functional. No cookies, nothing to hide.
