A throwaway consumer outside the repository declares every member as a file:
dependency, installs, and runs the installed executable with plain Node,
asserting the version it reports. That is the check a workspace link or a stale
lib/ in the checkout cannot pass for: it reads only what files selected.
The family declares its executable, so the vendored family — libraries a
consumer imports, with no executable — states that it has none instead of
carrying a probe that would prove nothing.
Both pack workflows run it after packing, still without credentials.
Each sequence gets its own workflow so the two version models never meet in one
file. Pack runs without credentials on every pull request and master push, so a
pull request proves the whole publish set still packs; publication is a manual
dispatch guarded by the npm-publish environment, runs only from that family's
tag, and never builds - it uploads the bytes pack produced.
