// 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 the build modules share is the Go build module's own package
// (mesh-catalog modules/mesh-build-go/buildstep), which imports this one.
