Field notes
The interface supports both backward-looking comparisons and forward projections, with a draggable growth assumption rather than a single fixed forecast. Its default 3.2% rate is attributed to the CPI-U 1913–2026 average, while the inflation example uses annual-average U.S. city CPI-U. Market comparisons can include reinvested dividends, and results can be packaged as either a “Ledger receipt” or “Parking sign” card for sharing.
