// Package buildstep is the contract of a build step every delivery part reads (novox/hq ADR 0593 §1): a step's id, the
// fetch request, a step a previous process left running and its end, a failure's words, a module tree's shape, the
// capacity setting and the launchers' names. The runner only the build modules run is this SDK's package steprun
// (design 47 G §464), which imports this one.
