US Sahm-rule labor-recession signals

Monthly US Sahm-rule recession signals from the BLS unemployment rate (FRED UNRATE, 1948 ->): the 3-month average unemployment rate minus its 12-month low (pp), with the 0.50pp recession trigger flag, a 0.30pp warning flag, a fast-rise flag, 3-month momentum, 30-month change volatility, 3-sigma anomaly flags, drift forecasts, a 5-year z-score, and the 12-month unemployment-rate change. The rule-based, transparent companion to us-recession-probability-signals (model probability) and the deterioration lens on us-labor-market-signals (raw levels). All rows normalized to country_code USA. Raw series: U.S. Bureau of Labor Statistics via FRED.
