Unclassified

Too few observations to classify this stack — a handful of connections can't tell a permuting client from coincidence.

catalog identity
No ground-truth build has reproduced this hello yet — absence is not a verdict.
self-randomisation
unclassified — only 1 observation(s) — too few to tell a permuting client from a coincidence.
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.

ClientHello anatomy

The underscore groups of JA4_r are the raw cipher suites · extensions · signature algorithms behind the hash.

Post-quantum key share
absent

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

Stored sorted — under one JA4 the wire order varies by construction, so no single order is “the” order.
