Checks 1–7

Handwritten digit recognition AI identifies, classifies, and interprets handwritten numbers (0-9) from images or inputs, commonly using Convolutional Neural Networks (CNN) for high accuracy, often over 97%. It frequently uses the MNIST dataset (60,000 training, 10,000 testing images) to train models, with applications in automated banking, check processing, and postal mail sorting

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.
