NRHow to read this registry. Status is what happened the last time that listing was called, and “Last observed” is the date of that call — the sweep is rolling, so those dates differ between rows. “Never probed” means no liveness observation has ever been recorded for the listing. NR means the evidence floor has not been met; it is not a low grade. Payment flow is observed inbound USDC within a disclosed Base block range, not revenue or proof of ownership.
