Agent identity, as an open registry.

Aria — the agent registry for identity and authorization — is an open standard on the W3C track, stewarded by the Trust Layer Foundation. Its whole operation is built on xyzDB — registering agents and tracking their activity — designed to scale to billions of records. Gravity groups it by organization, each tenant in its own block, so reading one org's activity grows in data but not in cost per query. None of it is vectors: it's the same co-location, at scale.
