Month-over-month and region-versus-region movement is withheld until the corpus has six or more complete months: with a shorter series, a change in a category median is dominated by a change in what was in the basket, and by flat-rate disposal lots whose price is an administrative convention. Each category's `modePrice`/`modeShare` shows how much of that contamination it carries.",
