Tereno Contract Guard

Is this Base contract safe to interact with? Detect whether an address has no code, is an upgradeable proxy, or is currently paused, and get a bounded allow, review or block trust verdict with evidence and block freshness before you call it. Positive-sum by design: $0.03 when nobody has checked this contract yet, $0.02 on a shared bytecode fingerprint, $0.01 once another agent has computed the full answer — and the wallet that computed it first earns a share of every reuse.
