INE 2024 tally sheet, type 2 scanner Ciudad De Mexico certified by comparison sample: capture differs from certified

Measured on AMD: Gemma-4-31B-IT, 124.7 s, $0.000126stored read

Rows sum to 496, TOTAL says 430: this field goes to a person, with its photo

Gemma's read breaks one of the paper's own checks, so the gate does not accept it.

Straightened by its corner marks; the right-hand column (officials' names and signatures) is blacked out before the page is stored or sent to the model.

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.

Receipts

Every disputed field of the sample audit of 300 sheets gets a Merkle receipt: its record, the SHA-256 of its crop, and a proof path to one published root. This sheet is not in that sample; see a receipt verified on sheet 122655C0100.

Separately: the official capture was wrong here

The official typed record (PREP), not Gemma's read

Option 01: the official capture keyed 64; the paper says 69 (certified count 69).

This compares the official typed record with the paper, not Gemma's read.

Options 01–15 are the form's vote rows in printed order, shown without party names. Digits and words are the model's two independent readings. Official capture: the double-keyed official capture of this image (PREP). Certified: the certified district count (Cómputos), which has no section 2-5 or 7 values. Amber: the capture differs from the model. † eye-checked: the capture mis-keyed the field. Against the official capture this read differs on 3 of 22 fields; after eye-checking, 2.
