Radar Perene / free
Today's reading
A public JSON endpoint. Brazil's regime reading today — Risk-BR score (0–100), categorical bucket, cross-engine divergence signals, declared freshness. Refreshes on its own. No signup, no API key, no per-user rate limits.
Why it is free
Methodological transparency is part of the thesis, not a favor. The reader who checks the reading every day before paying is the reader who understands — and who becomes a founder afterwards.

What is not here
Today's reading is today's state. It is not the historical series, not lens-level forecasting, not the manipulable quantile cone, not Lente Vértice. The daily editorial follow-up comes with Perene Semanal, temporarily paused.
