Who are you / the mirror turned around
What we see of you
Every non-human request here is measured and published. So here, turned around, is what we have already observed about you — nothing collected specially, just what the census logged. A User-Agent is a claim; a JA4 fingerprint is a property of your TLS stack.

Costume check
Your JA4 TLS fingerprint is shared with the other, differently-named identities listed above. At the TLS layer you are indistinguishable from them -- a User-Agent is a claim; a JA4 is a property.
Also worn by: ClaudeBot, Deno, GPTBot, OAI-SearchBot
A User-Agent is a claim; a JA4 is a property of your TLS stack. Everything here is only what we already observed of you, and it is public (CC0). Agents can get this in one call: GET /api/whoami or the fomite_whoami MCP tool.
