Core idea
The atlas was judged through three paths: structural validation, blind direction pairs, and pixel-level continuity. Each catches a different class of error.
Think of it this way: It is like checking a car: paperwork, a road test, and a mechanical inspection do not replace one another.
8 columns × 11 rows · last two rows = 16 look directions
How to read it
Structure confirms format, grid, and transparency.
Blind pairs test readability without revealing labels.
Continuity measures jumps between neighboring angles.
Technical layer
Continuity passed with two local outliers for review and no alpha holes. Blind validation passed cardinals and logged intermediate-diagonal warnings; independent visual QA closed as pass.
