catalog identity
Matches Android — Firebase / Play (Conscrypt) in the ground-truth catalogue.
self-randomisation
fixed — one JA3 across 46 connections: a deterministic stack. Libraries and command-line clients look like this.
reach
0.763 roams across 4 domains — spread is how evenly, not how many.

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.
