Real clients now authenticate every local publish against a static mock
OIDC issuer, and each type checks unauthenticated publishes are refused
while anonymous reads keep working.
npm clients need one registry for internal and public packages, but npm virtuals have no merger, so a local npm repo and npmjs cannot be served together.
- merge packuments across members: union versions (member order wins), first-defined dist-tags minus ones naming missing versions
- serve full and abbreviated (`install-v1`) packuments, scoped names included, via the shared virtual merge cache
- point tarballs at `<virtual>/<member>/<path>` and 302 them to the owning member
- reject an invalid Host with 400; serve virtual and local packuments `no-store` with `Vary: Host, X-Forwarded-Proto, Accept`
- return 502 when a member errors; skip members without the package
- add `docs/npm/virtual.md` and a stock `node:22` e2e-docker case
