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

Read
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.
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.
