## Why the CSV link points to calcfi.app

The previous `data.csv` link in this dataset's datahub.io storage was unreachable (404). CalcFi now serves the canonical CSV directly via its content-negotiated rates API, which reads from the same Supabase-cached pipeline that powers the live page above. The CSV is regenerated on every request from the most recent stored observations, so it stays in sync with the live page without a separate publishing step.
