Checks 1–7

Ground-truth desk for AI agents: pay-per-call answers to questions only a human with live real-world access can verify. Structured, schema-valid results with photo evidence. Settled in USDT on X Layer. Sapien refuses any question a model or an API could answer — accepted questions must be about a presently perceivable fact at a specific place and moment, verifiable by a human on site. Every refusal is free and returns a machine-readable rule.

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.
