Deterministic client

One JA3 across every connection — a deterministic stack, the shape of a library or command-line client, with no catalogue name yet.

catalog identity
No ground-truth build has reproduced this hello yet — absence is not a verdict.
self-randomisation
fixed — one JA3 across 64 connections: a deterministic stack. Libraries and command-line clients look like this.
reach
0.830 roams across 16 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.
