Measured, and partial. The roster is production’s (60 breaks, 9 hubs) and every number is one the project measured — the roster and the 33-year ocean statistics read from Supabase on 5 Nov 2026, the scores read from production’s ranked score view on 5 Nov 2026 (plus 2 breaks production has not scored, computed here from the same archive by its method). What is not held is shown as an absence, never a guess. Photos are of the real places, each credited; places near the breaks are from OpenStreetMap.
