Coverage & Divergence Map
Patterns × surfaces, computed from anatomy-level sightings. Each cell is a segmented ring — one segment per anatomy part, filled when that part is evidenced on that surface (hover any cell for part names and the last-evidence date; blank means no documented sighting yet). Anthropic surfaces are the seed corpus; OpenAI is the standing counterpart; other vendors join through the scout pipeline. Every cell traces to sources on the pattern page.

⬤ ring = one pattern's anatomy · 1 segment = 1 anatomy part · filled segment = part evidenced for that surface · hover a cell for its parts and last evidence · blank = no sighting yet
