RegistryDriver's constructor took a Baseline and stored it as a public
field it never read, and registry.spec.ts looped the whole suite over
BASELINES to pass it in — so eleven tests ran twice, identically. Every
supported line shares one documented registry contract, which is what the
driver already mirrors; the driver now takes no baseline and the suite runs
once. The per-tag complement, the ACTUAL dsh registry sources, still runs
in the compat project.
