Component 5 (access and affordability) is not computed: no store geography or income data are joined. Comparable index: chained Jevons over matched groups (A+B), base 13 Aug = 100, bootstrap band over groups; Dispersion: median within-group max$-$min log gap; Basket: Model E (B = 5). Composites are illustrative only and reported in the replication package.
