Methodology: values are the official per-$25 redemption values from Treasury's savings bond value file for the current redemption month, multiplied by face ÷ $25 (exact). The build verifies row counts, series coverage, value ranges, I-bond monotonicity, and the EE 20-year doubling guarantee before publishing; it refuses to deploy if any check fails.
