pub const EXIF_PAIR: &[(&str, &[u8])];Expand description
2026-09-26: The EXIF-orientation pair, kept out of the geometry ladder because the integrity leg checks what the model reports, not a token count.
Both store the same pixels, red on the top half and blue on the bottom, at
224x224. 15 carries Orientation = 6 (“rotate 90 CW to display”); 16
carries no EXIF. The engine applies the tag
(model-layers/src/vision_preprocess.rs), which carries the stored top
edge to the right, so the tagged image must read “right” and the untagged
one “top”.
