TIPS (Treasury Inflation-Protected Securities) yields by tenor

Real yields for TIPS securities. The live membership (FRED release 72) is resolved server-side and filtered by tenor (maturity 5/10/20/30 years); pass a maturity to keep the request small. Each security's observations are fetched with bounded concurrency and melted into a long series (date, symbol, due, name, value). Value is a decimal fraction (2.5% -> 0.025).
