Last 7 days (658 observations)

Distinct clients per day (last 30 days, peak 109/day)

Distinct clients are counted by IP-hash per complete UTC day — unlike observation counts this is insensitive to one chatty client, but NAT merges clients and address rotation splits them.

Browser / client	`Safari 13.0.3`

Note	`inferred from the self-declared string — a claim, not a measurement; compare with the wire fingerprints above`

Co-observed signals

Signals from other families seen in the same observation. A fingerprint spread thinly across many lower-layer signatures is a classic inconsistency signal.
