Last 7 days (19 observations)

Distinct clients per day (last 30 days, peak 11/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.

Decomposed attributes

Groups in wire order	`0a0a (GREASE), 11ec (X25519MLKEM768), 001d (x25519), 0017 (secp256r1), 0018 (secp384r1), 0019 (secp521r1)`
Group count	`6`

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.

Cross-transport links

TLS ClientHello fingerprints observed from the same client via the beacon's correlation id on the other transport (e.g. this stack over TCP ↔ that stack over QUIC).
