Every TypeScript module of a fetch gets the registry's latest SDK (ADR 0573 §2,
A-284), so the harness's machine named the real registry and 11 tests (9 unit,
11 integration runs) reached the network; with the resolver down they failed.
The harness now serves a registry of the test's own holding one SDK release,
and the userconfig test reads its address from it.
Builds: design 47 G A-284, A-285
