catalog identity
No ground-truth build has reproduced this hello yet — absence is not a verdict.
self-randomisation
randomising · 128+ JA3 — 100% of connections presented a JA3 never seen before for this client — it reshuffles its own ClientHello. Chrome has permuted extension order since version 110.
real-browser tell
Advertises X25519MLKEM768 (0x11ec), a post-quantum key share only current real browsers send.
reach
0.000effectively one destination.

Spread measures reach, not intent: it can’t tell one scraper visiting 500 domains from 500 people visiting one each. Stability is a claim about software — whether the stack is deterministic — nothing about who runs it.

Post-quantum key share
present (X25519MLKEM768)

The post-quantum key share is a structural fact about the hello, not a verdict — GREASE values are flagged the same neutral way.

JA3 hashes preserve wire order, so a permuting client mints a new one per connection; JA4 sorts the same set, which is why they share one JA4. Every hash here belongs to this fingerprint — there is no per-JA3 page. Showing the busiest 20.
