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 · 6 JA3 — only 6 observation(s) — too few to tell a permuting client from a coincidence.
reach
0.650 roams across 2 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

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.

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.
