- GDPC1 replaces A191RL1Q225SBEA: compute annualized QoQ growth from
GDP level ((val/prev)^4 - 1)*100 → displays proper ~2-3% not 31 819
- CPIAUCSL/CPILFESL/PCEPILFE: yoy_pct transform (val/val_12m_ago-1)*100
→ displays 3.x% YoY inflation, not raw index level 334
- ICSA: div1000 transform → displays 226 K claims, not 226 000 K
- delta_absolute flag: pp change for rate/% series, % change for levels
- SurprisePct component: shows 'pp' suffix for %, '%' for K/levels
- Column header renamed from 'Δ%' to 'Δ vs préc.' with tooltip
- Deprecated A191RL1Q225SBEA rows cleaned from DB on next bootstrap
- Warm-up periods: 2yr for yoy_pct, 3yr for qoq_annualized, 1yr others

- backend/services/fred_bootstrap.py: fetch 11 FRED series (PAYEMS, UNRATE, CPI, PCE, FEDFUNDS, ICSA, GDP, HY spread, T10Y2Y, T10Y3M) from public CSV endpoint — no API key needed; computes rolling z-scores and upserts into economic_events table
- backend/routers/eco.py: new /api/eco router with bootstrap (POST + status GET), events list with full filtering (date range, category, series, min z-score, direction, sort/pagination), series catalog, and db status endpoints
- backend/main.py: register eco router
- frontend/src/pages/CalendarPage.tsx: complete rewrite — real data table from /api/eco/events, Bootstrap FRED button with live polling, filter bar (date range, category, series chips, |z| threshold, direction), sort by date/z-score/series, pagination, z-score badges with color coding, sidebar with series inventory + geo alerts + z-score guide
