Editorial archive with migration mapper

A demo built for a specific brief. Not client work: the material shown is sample data, so what is on display is the mechanism.

I built an editorial archive with a migration mapper attached: article template, filterable index and reading time, plus a mapper that takes an export and reports what would break on import before anything is moved - on the placeholder export, 7 legacy rows produce 4 blocking problems and 1 warning, including a slug collision, a missing author, an ambiguous date format and an unmapped content kind.
