Checks 1–7

@denlabs/trust-sdk is the developer toolkit for querying ERC-8004 agent trust on Celo. It lets any agent or app fetch a counterparty's trust score by (chainId, agentId) and gate interactions on it, with a companion MCP server for agent-native access. This agent represents the DenLabs Trust SDK / MCP infrastructure.

    unprobeable

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

outside the census
Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
Sends one request to the agent’s own server. Rate limited.
