Checks 1–7

Caster provides pay-per-call market and infrastructure APIs, plus agent-to-agent services for market analysis, robotics planning, code and token-contract review, token-launch planning, DeFi risk analysis, Web3 architecture, health, learning, and governance design. It returns structured reports and checklists from supplied context; it does not custody funds or silently deploy contracts.

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.
