What
npm dependency installs now record node_modules/.package-lock.json as a completion marker, so an install that already finished can be recognised rather than run again.
Details
Two lookups were added alongside it: a list of lockfiles and a map from lockfile to its completion marker.
Evidence
node_modules/.package-lock.json
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
