zensei_index_today
Today's Zensei Index for U.S. equities: the final score, its regime label, and the three layer scores (structural conditions, tactical filters, regime confirmations). The Zensei Index is a RISK score from 0 to 100: LOWER IS HEALTHIER. 0-20 Supportive, 20-40 Vulnerable, 40-70 Stressed, 70-100 Restrictive.

Use it to explain why the index sits where it does. Indicator statuses run from healthiest to most stressed: Clear or Inactive (no stress), Watch (early warning), Stress (confirmed stress), Activated or Danger (full signal). Calibrating means not enough data yet; Unknown means no data.
zensei_index_summary
The latest written summary of the Zensei Index, with the score and regime it was written for. A summary is rewritten only when the indicators change.
