Hive Zk Attestation

Lets autonomous agents emit zero-knowledge proofs of their internal state without revealing it. Built for the MCP surface, targeting Aleo snarkVM with Varuna over BLS12-377 as the primary verifier. Exposes five tools: attest agent state by hashing it with a DID, anchor the commitment to Base L2, and verify against public zkSNARK infrastructure. This is RFC-stage plumbing, not production rails. The backend returns 503 until the Hive /v1/zk endpoints publish, and you'll need a separate BLS12-377 keypair for Aleo verification. Reach for this when two agents need to negotiate or audit without leaking inventory, model weights, or counterparty positions. No bridging, no custody, no wrapped assets.
