## Identity

Record key: agentarena.lol/mcp (the normalised endpoint observed)
Registry names (not anchored: no inclusion proof reaches this field): lol.agentarena/arena (what the registry said when we swept it, as observed by us, not evidence that the registry was correct, that the name belongs to whoever registered it, or that it still resolves)
Name reported by the server: agent-arena (self-reported, unverified, never used as identity)

Each observation carries a merkle leaf in the snapshot it belongs to. The chain
establishes that a root existed by a given time; it does not establish that any
measurement is true.
