Gemma-4-31B-IT reads the masked page on AMD; the gate checks each field as the answer arrives.

About a minute. One live read runs at a time for the whole site; yours waits in a short queue and shows its place.

Gate: Routed: 7 row labels not where expected; rows sum to TOTAL (345 vs 348); section 5 = section 7 (370 vs 345); section 7 = TOTAL (345 vs 348)

Amber: the capture differs from the model. † eye-checked: the capture mis-keyed the field.
