Results (200 images, 10 classes): Hotspot bundle 768D: 43.5% (4.3× random) Compressed 17D: 29.5% (2.9× random) All approaches at 768D: Grid lines: 29.8% (diffuse full-width scan) Hotspot: 43.5% (local attention) ← 46% better than grid Centroid focus: 50.5% (single best sweet spot, 432D) At 34 bytes: Grid→17D: 14.2% Hotspot→17D: 29.5% ← 2× grid compression quality Focus→17D: 28.5% The hotspot bundling captures LOCAL composition (what's AROUND each 1/3 intersection) vs grid lines which capture GLOBAL composition (what's ALONG each 1/3 line). Local attention wins by 46%. Next: chain with NARS predicate deduction. The visual detector finds S (bird at NW) and O (fence at SE). DeepNSM's distance matrix finds the nearest linking verb → P (perch).
