Explorer — §4 of the spec
Five reasoning operators on the cube.
MH-36, 264,583 H3-r9 clusters across 36 districts. Find twins runs the exact GUM-confidence-weighted standardised-Euclidean twin index (v2) over the 45-dim morphology vector; inspect reads the full evidence record, while compare + score + explain run on the 7 numeric columns + 12-bucket LULC one-hot cells-vector. Every response carries the cube fingerprint.
Showcase: 180 curated anchors. The cube has 264,583 clusters total — call /api/v1/cells/{admin:cluster} directly to inspect any cluster outside the showcase set.
Any cluster anchor in the 264,583-row MH-36 cube is queryable, not just showcase entries.
Cube. MH-36 (Maharashtra; 36 districts; 264,583 H3-r11 cluster anchors from sprint-7 mh36-unified-v1.7). Twin similarity is a GUM-confidence-weighted, magnitude-aware standardised-Euclidean distance over the 45-dim morphology vector v2 (33 numeric features incl. temporal + IMD-125yr climate-dynamics + NOAA-GSOD temperature + NRSC/GHSL built-up morphology-trajectory axes, with per-cell GUM trend uncertainty + 12-bucket LULC), mapped to a half-Gaussian kernel — the exact all-pairs index that fixed the v1 cosine degeneracy. The website surfaces a 180-anchor showcase subset; the full parquet lives in S3.
