Supported targets

migrate and readiness take a target as a compact spec — a distribution name followed by a major version, with no separator.

Vrtmv expands the spec to the distribution and version the Translation Index uses. rocky9 is the default target for both migrate and readiness.

The set of source→target pairs that carry vetted translations is defined by the Translation Index; a pair with no coverage yields untranslated canonicals rather than guesses. Migrations to Red Hat Enterprise Linux are treated as free targets for billing.
