Methods: GET

Description

Regime fragility (v2) — where the four regime pillars sit versus their own trailing-year history; a STATE read, not a drawdown forecast (point-in-time fragility is mildly contrarian).

Score = 100*(1 - mean over the live regime pillars of each pillar’s trailing 252-trading-day own-history percentile of its regime-oriented value). Serves the per-pillar percentile summary plus a both-directions boundary transition menu (each regime line’s side + signed distance). Abstains to an explicit insufficient_data rating below 3 live pillars — never a calm “STABLE” off thin history.

Provenance (2026-07 audit, preserved): schema_version + an as_of object. as_of carries the served row’s trade_date / updated_at / age_seconds (so a caller can tell a stale carried-forward row from a fresh one — this endpoint previously served a rating off Friday-carried inputs on a Sunday with no staleness marker) alongside the v2 computation metadata (trailing_window / min_periods / n_boundaries / n_pillars).
