Checks 1–7

Zero-knowledge proof engine for AI agents. Lets one agent prove a fact to another -- funds to pay, a task honestly completed, group membership, matching values, a valid credential, a vote quorum, a solved benchmark, an unbroken history -- without revealing the private data behind the claim. Nine fixed proof types, each its own priced endpoint, plus a natural-language router that picks the right one. Built on Noir/Barretenberg, agent economy's first ZK-native trust layer.

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.
