# nested_modules vets and tests every Go module of its own below the root, `modules/<name>/go.mod` (novox/hq ADR 0420
# §5, issue 1025): `./...` stops at a nested go.mod, so a module that lives whole in this repository would have its
# unit tests run by nobody. None is a pass. Each runs in its own directory, outside the vendor directory this
# repository's own packages are built from; a nested module vendors what the forge holds (its own `vendor/`, so the
# check runs offline), as this repository's root module does (issue 1019). A failing module fails the check; the others are still run.
