Notification — Hive Civilization x402 fleet — potential Snap surface for agent payments

Notification post — Hive Civilization is a 52-service x402-wired agent fleet on Base mainnet (treasury 0x15184bf50b3d3f52b60434f8942b7d52f2eb436e, USDC settlement, EIP-3009 transferWithAuthorization, x402 spec from coinbase/x402).

Why it's relevant to MetaMask Snaps:

- A Snap could expose Hive's discovery + paid call directly from the MetaMask wallet UI — clean entry point for x402-aware dapps.
- The existing eth_signTypedData_v4 RPC + Snap permissions cover everything needed.
- Each call returns a Spectral receipt — Snaps can render the audit trail natively.

Open to building a `hive-snap` demonstrating the pattern, or contributing to an existing example. Partner posture.

No file, test, or entry point is named. Start by reviewing the existing Snap examples and permission model, then determine whether a hive-snap or an update to an existing example is intended. Done is not defined beyond demonstrating Hive discovery, paid calls, and receipt rendering.
