Market Data Warehouse

yfinance → dbt → a dimensional (star-schema) warehouse: dim_date, dim_security, dim_exchange, and a fact-table family sharing that grain (fct_security_price, fct_security_technical_daily, fct_security_risk_daily, fct_corporate_action). This page reads straight off the built warehouse -- a live DuckDB query, not canned numbers. Runs on DuckDB or MotherDuck's free tier; the same dbt code also targets Snowflake.
